+Description: Device DAX is the device-centric analogue of Filesystem
+ DAX (CONFIG_FS_DAX). It allows memory ranges to be
+ allocated and mapped without need of an intervening file
+ system. Device DAX is strict, precise and predictable.
+ Specifically this interface:
+
+ 1/ Guarantees fault granularity with respect to a given
+ page size (pte, pmd, or pud) set at configuration time.
+
+ 2/ Enforces deterministic behavior by being strict about
+ what fault scenarios are supported.
+
+ The /sys/class/dax/ interface enumerates all the
+ device-dax instances in the system. The ABI is
+ deprecated and will be removed after 2020. It is
+ replaced with the DAX bus interface /sys/bus/dax/ where
+ device-dax instances can be found under
+ /sys/bus/dax/devices/

+<h3><a name="Forward Progress">Forward Progress</a></h3>
+
+<p>
+In theory, delaying grace-period completion and callback invocation
+is harmless.
+In practice, not only are memory sizes finite but also callbacks sometimes
+do wakeups, and sufficiently deferred wakeups can be difficult
+to distinguish from system hangs.
+Therefore, RCU must provide a number of mechanisms to promote forward
+progress.
+
+<p>
+These mechanisms are not foolproof, nor can they be.
+For one simple example, an infinite loop in an RCU read-side critical
+section must by definition prevent later grace periods from ever completing.
+For a more involved example, consider a 64-CPU system built with
+<tt>CONFIG_RCU_NOCB_CPU=y</tt> and booted with <tt>rcu_nocbs=1-63</tt>,
+where CPUs&nbsp;1 through&nbsp;63 spin in tight loops that invoke
+<tt>call_rcu()</tt>.
+Even if these tight loops also contain calls to <tt>cond_resched()</tt>
+(thus allowing grace periods to complete), CPU&nbsp;0 simply will
+not be able to invoke callbacks as fast as the other 63 CPUs can
+register them, at least not until the system runs out of memory.
+In both of these examples, the Spiderman principle applies: With great
+power comes great responsibility.
+However, short of this level of abuse, RCU is required to
+ensure timely completion of grace periods and timely invocation of
+callbacks.
+
+<p>
+RCU takes the following steps to encourage timely completion of
+grace periods:
+
+<ol>
+<li> If a grace period fails to complete within 100&nbsp;milliseconds,
+ RCU causes future invocations of <tt>cond_resched()</tt> on
+ the holdout CPUs to provide an RCU quiescent state.
+ RCU also causes those CPUs' <tt>need_resched()</tt> invocations
+ to return <tt>true</tt>, but only after the corresponding CPU's
+ next scheduling-clock.
+<li> CPUs mentioned in the <tt>nohz_full</tt> kernel boot parameter
+ can run indefinitely in the kernel without scheduling-clock
+ interrupts, which defeats the above <tt>need_resched()</tt>
+ strategem.
+ RCU will therefore invoke <tt>resched_cpu()</tt> on any
+ <tt>nohz_full</tt> CPUs still holding out after
+ 109&nbsp;milliseconds.
+<li> In kernels built with <tt>CONFIG_RCU_BOOST=y</tt>, if a given
+ task that has been preempted within an RCU read-side critical
+ section is holding out for more than 500&nbsp;milliseconds,
+ RCU will resort to priority boosting.
+<li> If a CPU is still holding out 10&nbsp;seconds into the grace
+ period, RCU will invoke <tt>resched_cpu()</tt> on it regardless
+ of its <tt>nohz_full</tt> state.
+</ol>
+
+<p>
+The above values are defaults for systems running with <tt>HZ=1000</tt>.
+They will vary as the value of <tt>HZ</tt> varies, and can also be
+changed using the relevant Kconfig options and kernel boot parameters.
+RCU currently does not do much sanity checking of these
+parameters, so please use caution when changing them.
+Note that these forward-progress measures are provided only for RCU,
+not for
+<a href="#Sleepable RCU">SRCU</a> or

+
+<p>
+RCU takes the following steps in <tt>call_rcu()</tt> to encourage timely
+invocation of callbacks when any given non-<tt>rcu_nocbs</tt> CPU has
+10,000 callbacks, or has 10,000 more callbacks than it had the last time
+encouragement was provided:
+
+<ol>
+<li> Starts a grace period, if one is not already in progress.
+<li> Forces immediate checking for quiescent states, rather than
+ waiting for three milliseconds to have elapsed since the
+ beginning of the grace period.
+<li> Immediately tags the CPU's callbacks with their grace period
+ completion numbers, rather than waiting for the <tt>RCU_SOFTIRQ</tt>
+ handler to get around to it.
+<li> Lifts callback-execution batch limits, which speeds up callback
+ invocation at the expense of degrading realtime response.

-MODULE PARAMETERS
-
-This module has the following parameters:
-
-fqs_duration Duration (in microseconds) of artificially induced bursts
- of force_quiescent_state() invocations. In RCU
- implementations having force_quiescent_state(), these
- bursts help force races between forcing a given grace
- period and that grace period ending on its own.
-
-fqs_holdoff Holdoff time (in microseconds) between consecutive calls
- to force_quiescent_state() within a burst.
-
-fqs_stutter Wait time (in seconds) between consecutive bursts
- of calls to force_quiescent_state().
-
-gp_normal Make the fake writers use normal synchronous grace-period
- primitives.
-
-gp_exp Make the fake writers use expedited synchronous grace-period
- primitives. If both gp_normal and gp_exp are set, or
- if neither gp_normal nor gp_exp are set, then randomly
- choose the primitive so that about 50% are normal and
- 50% expedited. By default, neither are set, which
- gives best overall test coverage.
-
-irqreader Says to invoke RCU readers from irq level. This is currently
- done via timers. Defaults to "1" for variants of RCU that
- permit this. (Or, more accurately, variants of RCU that do
- -not- permit this know to ignore this variable.)
-
-n_barrier_cbs If this is nonzero, RCU barrier testing will be conducted,
- in which case n_barrier_cbs specifies the number of
- RCU callbacks (and corresponding kthreads) to use for
- this testing. The value cannot be negative. If you
- specify this to be non-zero when torture_type indicates a
- synchronous RCU implementation (one for which a member of
- the synchronize_rcu() rather than the call_rcu() family is
- used -- see the documentation for torture_type below), an
- error will be reported and no testing will be carried out.
-
-nfakewriters This is the number of RCU fake writer threads to run. Fake
- writer threads repeatedly use the synchronous "wait for
- current readers" function of the interface selected by
- torture_type, with a delay between calls to allow for various
- different numbers of writers running in parallel.
- nfakewriters defaults to 4, which provides enough parallelism
- to trigger special cases caused by multiple writers, such as
- the synchronize_srcu() early return optimization.
-
-nreaders This is the number of RCU reading threads supported.
- The default is twice the number of CPUs. Why twice?
- To properly exercise RCU implementations with preemptible
- read-side critical sections.
-
-onoff_interval
- The number of seconds between each attempt to execute a
- randomly selected CPU-hotplug operation. Defaults to
- zero, which disables CPU hotplugging. In HOTPLUG_CPU=n
- kernels, rcutorture will silently refuse to do any
- CPU-hotplug operations regardless of what value is
- specified for onoff_interval.
-
-onoff_holdoff The number of seconds to wait until starting CPU-hotplug
- operations. This would normally only be used when
- rcutorture was built into the kernel and started
- automatically at boot time, in which case it is useful
- in order to avoid confusing boot-time code with CPUs
- coming and going.
-
-shuffle_interval
- The number of seconds to keep the test threads affinitied
- to a particular subset of the CPUs, defaults to 3 seconds.
- Used in conjunction with test_no_idle_hz.
-
-shutdown_secs The number of seconds to run the test before terminating
- the test and powering off the system. The default is
- zero, which disables test termination and system shutdown.
- This capability is useful for automated testing.
-
-stall_cpu The number of seconds that a CPU should be stalled while
- within both an rcu_read_lock() and a preempt_disable().
- This stall happens only once per rcutorture run.
- If you need multiple stalls, use modprobe and rmmod to
- repeatedly run rcutorture. The default for stall_cpu
- is zero, which prevents rcutorture from stalling a CPU.
-
- Note that attempts to rmmod rcutorture while the stall
- is ongoing will hang, so be careful what value you
- choose for this module parameter! In addition, too-large
- values for stall_cpu might well induce failures and
- warnings in other parts of the kernel. You have been
- warned!
-
-stall_cpu_holdoff
- The number of seconds to wait after rcutorture starts
- before stalling a CPU. Defaults to 10 seconds.
-
-stat_interval The number of seconds between output of torture
- statistics (via printk()). Regardless of the interval,
- statistics are printed when the module is unloaded.
- Setting the interval to zero causes the statistics to
- be printed -only- when the module is unloaded, and this
- is the default.
-
-stutter The length of time to run the test before pausing for this
- same period of time. Defaults to "stutter=5", so as
- to run and pause for (roughly) five-second intervals.
- Specifying "stutter=0" causes the test to run continuously
- without pausing, which is the old default behavior.
-
-test_boost Whether or not to test the ability of RCU to do priority
- boosting. Defaults to "test_boost=1", which performs
- RCU priority-inversion testing only if the selected
- RCU implementation supports priority boosting. Specifying
- "test_boost=0" never performs RCU priority-inversion
- testing. Specifying "test_boost=2" performs RCU
- priority-inversion testing even if the selected RCU
- implementation does not support RCU priority boosting,
- which can be used to test rcutorture's ability to
- carry out RCU priority-inversion testing.
-
-test_boost_interval
- The number of seconds in an RCU priority-inversion test
- cycle. Defaults to "test_boost_interval=7". It is
- usually wise for this value to be relatively prime to
- the value selected for "stutter".
-
-test_boost_duration
- The number of seconds to do RCU priority-inversion testing
- within any given "test_boost_interval". Defaults to
- "test_boost_duration=4".
-
-test_no_idle_hz Whether or not to test the ability of RCU to operate in
- a kernel that disables the scheduling-clock interrupt to
- idle CPUs. Boolean parameter, "1" to test, "0" otherwise.
- Defaults to omitting this test.
-
-torture_type The type of RCU to test, with string values as follows:
-
- "rcu": rcu_read_lock(), rcu_read_unlock() and call_rcu(),
- along with expedited, synchronous, and polling
- variants.
-
- "rcu_bh": rcu_read_lock_bh(), rcu_read_unlock_bh(), and

- "rcu_busted": This tests an intentionally incorrect version
- of RCU in order to help test rcutorture itself.

+=========
+SafeSetID
+=========
+SafeSetID is an LSM module that gates the setid family of syscalls to restrict
+UID/GID transitions from a given UID/GID to only those approved by a
+system-wide whitelist. These restrictions also prohibit the given UIDs/GIDs
+from obtaining auxiliary privileges associated with CAP_SET{U/G}ID, such as
+allowing a user to set up user namespace UID mappings.
+
+
+Background
+==========
+In absence of file capabilities, processes spawned on a Linux system that need
+to switch to a different user must be spawned with CAP_SETUID privileges.
+CAP_SETUID is granted to programs running as root or those running as a non-root
+user that have been explicitly given the CAP_SETUID runtime capability. It is
+often preferable to use Linux runtime capabilities rather than file
+capabilities, since using file capabilities to run a program with elevated
+privileges opens up possible security holes since any user with access to the
+file can exec() that program to gain the elevated privileges.
+
+While it is possible to implement a tree of processes by giving full
+CAP_SET{U/G}ID capabilities, this is often at odds with the goals of running a
+tree of processes under non-root user(s) in the first place. Specifically,
+since CAP_SETUID allows changing to any user on the system, including the root
+user, it is an overpowered capability for what is needed in this scenario,
+especially since programs often only call setuid() to drop privileges to a
+lesser-privileged user -- not elevate privileges. Unfortunately, there is no
+generally feasible way in Linux to restrict the potential UIDs that a user can
+switch to through setuid() beyond allowing a switch to any user on the system.
+This SafeSetID LSM seeks to provide a solution for restricting setid
+capabilities in such a way.
+
+The main use case for this LSM is to allow a non-root program to transition to
+other untrusted uids without full blown CAP_SETUID capabilities. The non-root
+program would still need CAP_SETUID to do any kind of transition, but the
+additional restrictions imposed by this LSM would mean it is a "safer" version
+of CAP_SETUID since the non-root program cannot take advantage of CAP_SETUID to
+do any unapproved actions (e.g. setuid to uid 0 or create/enter new user
+namespace). The higher level goal is to allow for uid-based sandboxing of system
+services without having to give out CAP_SETUID all over the place just so that
+non-root programs can drop to even-lesser-privileged uids. This is especially
+relevant when one non-root daemon on the system should be allowed to spawn other
+processes as different uids, but its undesirable to give the daemon a
+basically-root-equivalent CAP_SETUID.
+
+
+Other Approaches Considered
+===========================
+
+Solve this problem in userspace
+-------------------------------
+For candidate applications that would like to have restricted setid capabilities
+as implemented in this LSM, an alternative option would be to simply take away
+setid capabilities from the application completely and refactor the process
+spawning semantics in the application (e.g. by using a privileged helper program
+to do process spawning and UID/GID transitions). Unfortunately, there are a
+number of semantics around process spawning that would be affected by this, such
+as fork() calls where the program doesn???t immediately call exec() after the
+fork(), parent processes specifying custom environment variables or command line
+args for spawned child processes, or inheritance of file handles across a
+fork()/exec(). Because of this, as solution that uses a privileged helper in
+userspace would likely be less appealing to incorporate into existing projects
+that rely on certain process-spawning semantics in Linux.
+
+Use user namespaces
+-------------------
+Another possible approach would be to run a given process tree in its own user
+namespace and give programs in the tree setid capabilities. In this way,
+programs in the tree could change to any desired UID/GID in the context of their
+own user namespace, and only approved UIDs/GIDs could be mapped back to the
+initial system user namespace, affectively preventing privilege escalation.
+Unfortunately, it is not generally feasible to use user namespaces in isolation,
+without pairing them with other namespace types, which is not always an option.
+Linux checks for capabilities based off of the user namespace that ???owns??? some
+entity. For example, Linux has the notion that network namespaces are owned by
+the user namespace in which they were created. A consequence of this is that
+capability checks for access to a given network namespace are done by checking
+whether a task has the given capability in the context of the user namespace
+that owns the network namespace -- not necessarily the user namespace under
+which the given task runs. Therefore spawning a process in a new user namespace
+effectively prevents it from accessing the network namespace owned by the
+initial namespace. This is a deal-breaker for any application that expects to
+retain the CAP_NET_ADMIN capability for the purpose of adjusting network
+configurations. Using user namespaces in isolation causes problems regarding
+other system interactions, including use of pid namespaces and device creation.
+
+Use an existing LSM
+-------------------
+None of the other in-tree LSMs have the capability to gate setid transitions, or
+even employ the security_task_fix_setuid hook at all. SELinux says of that hook:
+"Since setuid only affects the current process, and since the SELinux controls
+are not based on the Linux identity attributes, SELinux does not need to control
+this operation."
+
+
+Directions for use
+==================
+This LSM hooks the setid syscalls to make sure transitions are allowed if an
+applicable restriction policy is in place. Policies are configured through
+securityfs by writing to the safesetid/add_whitelist_policy and
+safesetid/flush_whitelist_policies files at the location where securityfs is
+mounted. The format for adding a policy is '<UID>:<UID>', using literal
+numbers, such as '123:456'. To flush the policies, any write to the file is
+sufficient. Again, configuring a policy for a UID will prevent that UID from
+obtaining auxiliary setid privileges, such as allowing a user to set up user
+namespace UID mappings.

+Cpuset
+------
+
+The "cpuset" controller provides a mechanism for constraining
+the CPU and memory node placement of tasks to only the resources
+specified in the cpuset interface files in a task's current cgroup.
+This is especially valuable on large NUMA systems where placing jobs
+on properly sized subsets of the systems with careful processor and
+memory placement to reduce cross-node memory access and contention
+can improve overall system performance.
+
+The "cpuset" controller is hierarchical. That means the controller
+cannot use CPUs or memory nodes not allowed in its parent.
+
+
+Cpuset Interface Files
+~~~~~~~~~~~~~~~~~~~~~~
+
+ cpuset.cpus
+ A read-write multiple values file which exists on non-root
+ cpuset-enabled cgroups.
+
+ It lists the requested CPUs to be used by tasks within this
+ cgroup. The actual list of CPUs to be granted, however, is
+ subjected to constraints imposed by its parent and can differ
+ from the requested CPUs.
+
+ The CPU numbers are comma-separated numbers or ranges.
+ For example:
+
+ # cat cpuset.cpus
+ 0-4,6,8-10
+
+ An empty value indicates that the cgroup is using the same
+ setting as the nearest cgroup ancestor with a non-empty
+ "cpuset.cpus" or all the available CPUs if none is found.
+
+ The value of "cpuset.cpus" stays constant until the next update
+ and won't be affected by any CPU hotplug events.
+
+ cpuset.cpus.effective
+ A read-only multiple values file which exists on all
+ cpuset-enabled cgroups.
+
+ It lists the onlined CPUs that are actually granted to this
+ cgroup by its parent. These CPUs are allowed to be used by
+ tasks within the current cgroup.
+
+ If "cpuset.cpus" is empty, the "cpuset.cpus.effective" file shows
+ all the CPUs from the parent cgroup that can be available to
+ be used by this cgroup. Otherwise, it should be a subset of
+ "cpuset.cpus" unless none of the CPUs listed in "cpuset.cpus"
+ can be granted. In this case, it will be treated just like an
+ empty "cpuset.cpus".
+
+ Its value will be affected by CPU hotplug events.
+
+ cpuset.mems
+ A read-write multiple values file which exists on non-root
+ cpuset-enabled cgroups.
+
+ It lists the requested memory nodes to be used by tasks within
+ this cgroup. The actual list of memory nodes granted, however,
+ is subjected to constraints imposed by its parent and can differ
+ from the requested memory nodes.
+
+ The memory node numbers are comma-separated numbers or ranges.
+ For example:
+
+ # cat cpuset.mems
+ 0-1,3
+
+ An empty value indicates that the cgroup is using the same
+ setting as the nearest cgroup ancestor with a non-empty
+ "cpuset.mems" or all the available memory nodes if none
+ is found.
+
+ The value of "cpuset.mems" stays constant until the next update
+ and won't be affected by any memory nodes hotplug events.
+
+ cpuset.mems.effective
+ A read-only multiple values file which exists on all
+ cpuset-enabled cgroups.
+
+ It lists the onlined memory nodes that are actually granted to
+ this cgroup by its parent. These memory nodes are allowed to
+ be used by tasks within the current cgroup.
+
+ If "cpuset.mems" is empty, it shows all the memory nodes from the
+ parent cgroup that will be available to be used by this cgroup.
+ Otherwise, it should be a subset of "cpuset.mems" unless none of
+ the memory nodes listed in "cpuset.mems" can be granted. In this
+ case, it will be treated just like an empty "cpuset.mems".
+
+ Its value will be affected by memory nodes hotplug events.
+
+ cpuset.cpus.partition
+ A read-write single value file which exists on non-root
+ cpuset-enabled cgroups. This flag is owned by the parent cgroup
+ and is not delegatable.
+
+ It accepts only the following input values when written to.
+
+ "root" - a paritition root
+ "member" - a non-root member of a partition
+
+ When set to be a partition root, the current cgroup is the
+ root of a new partition or scheduling domain that comprises
+ itself and all its descendants except those that are separate
+ partition roots themselves and their descendants. The root
+ cgroup is always a partition root.
+
+ There are constraints on where a partition root can be set.
+ It can only be set in a cgroup if all the following conditions
+ are true.
+
+ 1) The "cpuset.cpus" is not empty and the list of CPUs are
+ exclusive, i.e. they are not shared by any of its siblings.
+ 2) The parent cgroup is a partition root.
+ 3) The "cpuset.cpus" is also a proper subset of the parent's
+ "cpuset.cpus.effective".
+ 4) There is no child cgroups with cpuset enabled. This is for
+ eliminating corner cases that have to be handled if such a
+ condition is allowed.
+
+ Setting it to partition root will take the CPUs away from the
+ effective CPUs of the parent cgroup. Once it is set, this
+ file cannot be reverted back to "member" if there are any child
+ cgroups with cpuset enabled.
+
+ A parent partition cannot distribute all its CPUs to its
+ child partitions. There must be at least one cpu left in the
+ parent partition.
+
+ Once becoming a partition root, changes to "cpuset.cpus" is
+ generally allowed as long as the first condition above is true,
+ the change will not take away all the CPUs from the parent
+ partition and the new "cpuset.cpus" value is a superset of its
+ children's "cpuset.cpus" values.
+
+ Sometimes, external factors like changes to ancestors'
+ "cpuset.cpus" or cpu hotplug can cause the state of the partition
+ root to change. On read, the "cpuset.sched.partition" file
+ can show the following values.
+
+ "member" Non-root member of a partition
+ "root" Partition root
+ "root invalid" Invalid partition root
+
+ It is a partition root if the first 2 partition root conditions
+ above are true and at least one CPU from "cpuset.cpus" is
+ granted by the parent cgroup.
+
+ A partition root can become invalid if none of CPUs requested
+ in "cpuset.cpus" can be granted by the parent cgroup or the
+ parent cgroup is no longer a partition root itself. In this
+ case, it is not a real partition even though the restriction
+ of the first partition root condition above will still apply.
+ The cpu affinity of all the tasks in the cgroup will then be
+ associated with CPUs in the nearest ancestor partition.
+
+ An invalid partition root can be transitioned back to a
+ real partition root if at least one of the requested CPUs
+ can now be granted by its parent. In this case, the cpu
+ affinity of all the tasks in the formerly invalid partition
+ will be associated to the CPUs of the newly formed partition.
+ Changing the partition state of an invalid partition root to
+ "member" is always allowed even if child cpusets are present.

+Perf Events and tool security
+=============================
+
+Overview
+--------
+
+Usage of Performance Counters for Linux (perf_events) [1]_ , [2]_ , [3]_
+can impose a considerable risk of leaking sensitive data accessed by
+monitored processes. The data leakage is possible both in scenarios of
+direct usage of perf_events system call API [2]_ and over data files
+generated by Perf tool user mode utility (Perf) [3]_ , [4]_ . The risk
+depends on the nature of data that perf_events performance monitoring
+units (PMU) [2]_ and Perf collect and expose for performance analysis.
+Collected system and performance data may be split into several
+categories:
+
+1. System hardware and software configuration data, for example: a CPU
+ model and its cache configuration, an amount of available memory and
+ its topology, used kernel and Perf versions, performance monitoring
+ setup including experiment time, events configuration, Perf command
+ line parameters, etc.
+
+2. User and kernel module paths and their load addresses with sizes,
+ process and thread names with their PIDs and TIDs, timestamps for
+ captured hardware and software events.
+
+3. Content of kernel software counters (e.g., for context switches, page
+ faults, CPU migrations), architectural hardware performance counters
+ (PMC) [8]_ and machine specific registers (MSR) [9]_ that provide
+ execution metrics for various monitored parts of the system (e.g.,
+ memory controller (IMC), interconnect (QPI/UPI) or peripheral (PCIe)
+ uncore counters) without direct attribution to any execution context
+ state.
+
+4. Content of architectural execution context registers (e.g., RIP, RSP,
+ RBP on x86_64), process user and kernel space memory addresses and
+ data, content of various architectural MSRs that capture data from
+ this category.
+
+Data that belong to the fourth category can potentially contain
+sensitive process data. If PMUs in some monitoring modes capture values
+of execution context registers or data from process memory then access
+to such monitoring capabilities requires to be ordered and secured
+properly. So, perf_events/Perf performance monitoring is the subject for
+security access control management [5]_ .
+
+perf_events/Perf access control
+-------------------------------
+
+To perform security checks, the Linux implementation splits processes
+into two categories [6]_ : a) privileged processes (whose effective user
+ID is 0, referred to as superuser or root), and b) unprivileged
+processes (whose effective UID is nonzero). Privileged processes bypass
+all kernel security permission checks so perf_events performance
+monitoring is fully available to privileged processes without access,
+scope and resource restrictions.
+
+Unprivileged processes are subject to a full security permission check
+based on the process's credentials [5]_ (usually: effective UID,
+effective GID, and supplementary group list).
+
+Linux divides the privileges traditionally associated with superuser
+into distinct units, known as capabilities [6]_ , which can be
+independently enabled and disabled on per-thread basis for processes and
+files of unprivileged users.
+
+Unprivileged processes with enabled CAP_SYS_ADMIN capability are treated
+as privileged processes with respect to perf_events performance
+monitoring and bypass *scope* permissions checks in the kernel.
+
+Unprivileged processes using perf_events system call API is also subject
+for PTRACE_MODE_READ_REALCREDS ptrace access mode check [7]_ , whose
+outcome determines whether monitoring is permitted. So unprivileged
+processes provided with CAP_SYS_PTRACE capability are effectively
+permitted to pass the check.
+
+Other capabilities being granted to unprivileged processes can
+effectively enable capturing of additional data required for later
+performance analysis of monitored processes or a system. For example,
+CAP_SYSLOG capability permits reading kernel space memory addresses from
+/proc/kallsyms file.
+
+perf_events/Perf privileged users
+---------------------------------
+
+Mechanisms of capabilities, privileged capability-dumb files [6]_ and
+file system ACLs [10]_ can be used to create a dedicated group of
+perf_events/Perf privileged users who are permitted to execute
+performance monitoring without scope limits. The following steps can be
+taken to create such a group of privileged Perf users.
+
+1. Create perf_users group of privileged Perf users, assign perf_users
+ group to Perf tool executable and limit access to the executable for
+ other users in the system who are not in the perf_users group:
+
+::
+
+ # groupadd perf_users
+ # ls -alhF
+ -rwxr-xr-x 2 root root 11M Oct 19 15:12 perf
+ # chgrp perf_users perf
+ # ls -alhF
+ -rwxr-xr-x 2 root perf_users 11M Oct 19 15:12 perf
+ # chmod o-rwx perf
+ # ls -alhF
+ -rwxr-x--- 2 root perf_users 11M Oct 19 15:12 perf
+
+2. Assign the required capabilities to the Perf tool executable file and
+ enable members of perf_users group with performance monitoring
+ privileges [6]_ :
+
+::
+
+ # setcap "cap_sys_admin,cap_sys_ptrace,cap_syslog=ep" perf
+ # setcap -v "cap_sys_admin,cap_sys_ptrace,cap_syslog=ep" perf
+ perf: OK
+ # getcap perf
+ perf = cap_sys_ptrace,cap_sys_admin,cap_syslog+ep
+
+As a result, members of perf_users group are capable of conducting
+performance monitoring by using functionality of the configured Perf
+tool executable that, when executes, passes perf_events subsystem scope
+checks.
+
+This specific access control management is only available to superuser
+or root running processes with CAP_SETPCAP, CAP_SETFCAP [6]_
+capabilities.
+
+perf_events/Perf unprivileged users
+-----------------------------------
+
+perf_events/Perf *scope* and *access* control for unprivileged processes
+is governed by perf_event_paranoid [2]_ setting:
+
+-1:
+ Impose no *scope* and *access* restrictions on using perf_events
+ performance monitoring. Per-user per-cpu perf_event_mlock_kb [2]_
+ locking limit is ignored when allocating memory buffers for storing
+ performance data. This is the least secure mode since allowed
+ monitored *scope* is maximized and no perf_events specific limits
+ are imposed on *resources* allocated for performance monitoring.
+
+>=0:
+ *scope* includes per-process and system wide performance monitoring
+ but excludes raw tracepoints and ftrace function tracepoints
+ monitoring. CPU and system events happened when executing either in
+ user or in kernel space can be monitored and captured for later
+ analysis. Per-user per-cpu perf_event_mlock_kb locking limit is
+ imposed but ignored for unprivileged processes with CAP_IPC_LOCK
+ [6]_ capability.
+
+>=1:
+ *scope* includes per-process performance monitoring only and
+ excludes system wide performance monitoring. CPU and system events
+ happened when executing either in user or in kernel space can be
+ monitored and captured for later analysis. Per-user per-cpu
+ perf_event_mlock_kb locking limit is imposed but ignored for
+ unprivileged processes with CAP_IPC_LOCK capability.
+
+>=2:
+ *scope* includes per-process performance monitoring only. CPU and
+ system events happened when executing in user space only can be
+ monitored and captured for later analysis. Per-user per-cpu
+ perf_event_mlock_kb locking limit is imposed but ignored for
+ unprivileged processes with CAP_IPC_LOCK capability.
+
+perf_events/Perf resource control
+---------------------------------
+
+Open file descriptors
++++++++++++++++++++++
+
+The perf_events system call API [2]_ allocates file descriptors for
+every configured PMU event. Open file descriptors are a per-process
+accountable resource governed by the RLIMIT_NOFILE [11]_ limit
+(ulimit -n), which is usually derived from the login shell process. When
+configuring Perf collection for a long list of events on a large server
+system, this limit can be easily hit preventing required monitoring
+configuration. RLIMIT_NOFILE limit can be increased on per-user basis
+modifying content of the limits.conf file [12]_ . Ordinarily, a Perf
+sampling session (perf record) requires an amount of open perf_event
+file descriptors that is not less than the number of monitored events
+multiplied by the number of monitored CPUs.
+
+Memory allocation
++++++++++++++++++
+
+The amount of memory available to user processes for capturing
+performance monitoring data is governed by the perf_event_mlock_kb [2]_
+setting. This perf_event specific resource setting defines overall
+per-cpu limits of memory allowed for mapping by the user processes to
+execute performance monitoring. The setting essentially extends the
+RLIMIT_MEMLOCK [11]_ limit, but only for memory regions mapped
+specifically for capturing monitored performance events and related data.
+
+For example, if a machine has eight cores and perf_event_mlock_kb limit
+is set to 516 KiB, then a user process is provided with 516 KiB * 8 =
+4128 KiB of memory above the RLIMIT_MEMLOCK limit (ulimit -l) for
+perf_event mmap buffers. In particular, this means that, if the user
+wants to start two or more performance monitoring processes, the user is
+required to manually distribute the available 4128 KiB between the
+monitoring processes, for example, using the --mmap-pages Perf record
+mode option. Otherwise, the first started performance monitoring process
+allocates all available 4128 KiB and the other processes will fail to
+proceed due to the lack of memory.
+
+RLIMIT_MEMLOCK and perf_event_mlock_kb resource constraints are ignored
+for processes with the CAP_IPC_LOCK capability. Thus, perf_events/Perf
+privileged users can be provided with memory above the constraints for
+perf_events/Perf performance monitoring purpose by providing the Perf
+executable with CAP_IPC_LOCK capability.

+CPU Idle Time Management
+========================

+
+Concepts
+========
+
+Modern processors are generally able to enter states in which the execution of
+a program is suspended and instructions belonging to it are not fetched from
+memory or executed. Those states are the *idle* states of the processor.
+
+Since part of the processor hardware is not used in idle states, entering them
+generally allows power drawn by the processor to be reduced and, in consequence,
+it is an opportunity to save energy.
+
+CPU idle time management is an energy-efficiency feature concerned about using
+the idle states of processors for this purpose.
+
+Logical CPUs
+------------
+
+CPU idle time management operates on CPUs as seen by the *CPU scheduler* (that
+is the part of the kernel responsible for the distribution of computational
+work in the system). In its view, CPUs are *logical* units. That is, they need
+not be separate physical entities and may just be interfaces appearing to
+software as individual single-core processors. In other words, a CPU is an
+entity which appears to be fetching instructions that belong to one sequence
+(program) from memory and executing them, but it need not work this way
+physically. Generally, three different cases can be consider here.
+
+First, if the whole processor can only follow one sequence of instructions (one
+program) at a time, it is a CPU. In that case, if the hardware is asked to
+enter an idle state, that applies to the processor as a whole.
+
+Second, if the processor is multi-core, each core in it is able to follow at
+least one program at a time. The cores need not be entirely independent of each
+other (for example, they may share caches), but still most of the time they
+work physically in parallel with each other, so if each of them executes only
+one program, those programs run mostly independently of each other at the same
+time. The entire cores are CPUs in that case and if the hardware is asked to
+enter an idle state, that applies to the core that asked for it in the first
+place, but it also may apply to a larger unit (say a "package" or a "cluster")
+that the core belongs to (in fact, it may apply to an entire hierarchy of larger
+units containing the core). Namely, if all of the cores in the larger unit
+except for one have been put into idle states at the "core level" and the
+remaining core asks the processor to enter an idle state, that may trigger it
+to put the whole larger unit into an idle state which also will affect the
+other cores in that unit.
+
+Finally, each core in a multi-core processor may be able to follow more than one
+program in the same time frame (that is, each core may be able to fetch
+instructions from multiple locations in memory and execute them in the same time
+frame, but not necessarily entirely in parallel with each other). In that case
+the cores present themselves to software as "bundles" each consisting of
+multiple individual single-core "processors", referred to as *hardware threads*
+(or hyper-threads specifically on Intel hardware), that each can follow one
+sequence of instructions. Then, the hardware threads are CPUs from the CPU idle
+time management perspective and if the processor is asked to enter an idle state
+by one of them, the hardware thread (or CPU) that asked for it is stopped, but
+nothing more happens, unless all of the other hardware threads within the same
+core also have asked the processor to enter an idle state. In that situation,
+the core may be put into an idle state individually or a larger unit containing
+it may be put into an idle state as a whole (if the other cores within the
+larger unit are in idle states already).
+
+Idle CPUs
+---------
+
+Logical CPUs, simply referred to as "CPUs" in what follows, are regarded as
+*idle* by the Linux kernel when there are no tasks to run on them except for the
+special "idle" task.
+
+Tasks are the CPU scheduler's representation of work. Each task consists of a
+sequence of instructions to execute, or code, data to be manipulated while
+running that code, and some context information that needs to be loaded into the
+processor every time the task's code is run by a CPU. The CPU scheduler
+distributes work by assigning tasks to run to the CPUs present in the system.
+
+Tasks can be in various states. In particular, they are *runnable* if there are
+no specific conditions preventing their code from being run by a CPU as long as
+there is a CPU available for that (for example, they are not waiting for any
+events to occur or similar). When a task becomes runnable, the CPU scheduler
+assigns it to one of the available CPUs to run and if there are no more runnable
+tasks assigned to it, the CPU will load the given task's context and run its
+code (from the instruction following the last one executed so far, possibly by
+another CPU). [If there are multiple runnable tasks assigned to one CPU
+simultaneously, they will be subject to prioritization and time sharing in order
+to allow them to make some progress over time.]
+
+The special "idle" task becomes runnable if there are no other runnable tasks
+assigned to the given CPU and the CPU is then regarded as idle. In other words,
+in Linux idle CPUs run the code of the "idle" task called *the idle loop*. That
+code may cause the processor to be put into one of its idle states, if they are
+supported, in order to save energy, but if the processor does not support any
+idle states, or there is not enough time to spend in an idle state before the
+next wakeup event, or there are strict latency constraints preventing any of the
+available idle states from being used, the CPU will simply execute more or less
+useless instructions in a loop until it is assigned a new task to run.
+
+
+.. _idle-loop:
+
+The Idle Loop
+=============
+
+The idle loop code takes two major steps in every iteration of it. First, it
+calls into a code module referred to as the *governor* that belongs to the CPU
+idle time management subsystem called ``CPUIdle`` to select an idle state for
+the CPU to ask the hardware to enter. Second, it invokes another code module
+from the ``CPUIdle`` subsystem, called the *driver*, to actually ask the
+processor hardware to enter the idle state selected by the governor.
+
+The role of the governor is to find an idle state most suitable for the
+conditions at hand. For this purpose, idle states that the hardware can be
+asked to enter by logical CPUs are represented in an abstract way independent of
+the platform or the processor architecture and organized in a one-dimensional
+(linear) array. That array has to be prepared and supplied by the ``CPUIdle``
+driver matching the platform the kernel is running on at the initialization
+time. This allows ``CPUIdle`` governors to be independent of the underlying
+hardware and to work with any platforms that the Linux kernel can run on.
+
+Each idle state present in that array is characterized by two parameters to be
+taken into account by the governor, the *target residency* and the (worst-case)
+*exit latency*. The target residency is the minimum time the hardware must
+spend in the given state, including the time needed to enter it (which may be
+substantial), in order to save more energy than it would save by entering one of
+the shallower idle states instead. [The "depth" of an idle state roughly
+corresponds to the power drawn by the processor in that state.] The exit
+latency, in turn, is the maximum time it will take a CPU asking the processor
+hardware to enter an idle state to start executing the first instruction after a
+wakeup from that state. Note that in general the exit latency also must cover
+the time needed to enter the given state in case the wakeup occurs when the
+hardware is entering it and it must be entered completely to be exited in an
+ordered manner.
+
+There are two types of information that can influence the governor's decisions.
+First of all, the governor knows the time until the closest timer event. That
+time is known exactly, because the kernel programs timers and it knows exactly
+when they will trigger, and it is the maximum time the hardware that the given
+CPU depends on can spend in an idle state, including the time necessary to enter
+and exit it. However, the CPU may be woken up by a non-timer event at any time
+(in particular, before the closest timer triggers) and it generally is not known
+when that may happen. The governor can only see how much time the CPU actually
+was idle after it has been woken up (that time will be referred to as the *idle
+duration* from now on) and it can use that information somehow along with the
+time until the closest timer to estimate the idle duration in future. How the
+governor uses that information depends on what algorithm is implemented by it
+and that is the primary reason for having more than one governor in the
+``CPUIdle`` subsystem.
+
+There are three ``CPUIdle`` governors available, ``menu``, `TEO <teo-gov_>`_
+and ``ladder``. Which of them is used by default depends on the configuration
+of the kernel and in particular on whether or not the scheduler tick can be
+`stopped by the idle loop <idle-cpus-and-tick_>`_. It is possible to change the
+governor at run time if the ``cpuidle_sysfs_switch`` command line parameter has
+been passed to the kernel, but that is not safe in general, so it should not be
+done on production systems (that may change in the future, though). The name of
+the ``CPUIdle`` governor currently used by the kernel can be read from the
+:file:`current_governor_ro` (or :file:`current_governor` if
+``cpuidle_sysfs_switch`` is present in the kernel command line) file under
+:file:`/sys/devices/system/cpu/cpuidle/` in ``sysfs``.
+
+Which ``CPUIdle`` driver is used, on the other hand, usually depends on the
+platform the kernel is running on, but there are platforms with more than one
+matching driver. For example, there are two drivers that can work with the
+majority of Intel platforms, ``intel_idle`` and ``acpi_idle``, one with
+hardcoded idle states information and the other able to read that information
+from the system's ACPI tables, respectively. Still, even in those cases, the
+driver chosen at the system initialization time cannot be replaced later, so the
+decision on which one of them to use has to be made early (on Intel platforms
+the ``acpi_idle`` driver will be used if ``intel_idle`` is disabled for some
+reason or if it does not recognize the processor). The name of the ``CPUIdle``
+driver currently used by the kernel can be read from the :file:`current_driver`
+file under :file:`/sys/devices/system/cpu/cpuidle/` in ``sysfs``.
+
+
+.. _idle-cpus-and-tick:
+
+Idle CPUs and The Scheduler Tick
+================================
+
+The scheduler tick is a timer that triggers periodically in order to implement
+the time sharing strategy of the CPU scheduler. Of course, if there are
+multiple runnable tasks assigned to one CPU at the same time, the only way to
+allow them to make reasonable progress in a given time frame is to make them
+share the available CPU time. Namely, in rough approximation, each task is
+given a slice of the CPU time to run its code, subject to the scheduling class,
+prioritization and so on and when that time slice is used up, the CPU should be
+switched over to running (the code of) another task. The currently running task
+may not want to give the CPU away voluntarily, however, and the scheduler tick
+is there to make the switch happen regardless. That is not the only role of the
+tick, but it is the primary reason for using it.
+
+The scheduler tick is problematic from the CPU idle time management perspective,
+because it triggers periodically and relatively often (depending on the kernel
+configuration, the length of the tick period is between 1 ms and 10 ms).
+Thus, if the tick is allowed to trigger on idle CPUs, it will not make sense
+for them to ask the hardware to enter idle states with target residencies above
+the tick period length. Moreover, in that case the idle duration of any CPU
+will never exceed the tick period length and the energy used for entering and
+exiting idle states due to the tick wakeups on idle CPUs will be wasted.
+
+Fortunately, it is not really necessary to allow the tick to trigger on idle
+CPUs, because (by definition) they have no tasks to run except for the special
+"idle" one. In other words, from the CPU scheduler perspective, the only user
+of the CPU time on them is the idle loop. Since the time of an idle CPU need
+not be shared between multiple runnable tasks, the primary reason for using the
+tick goes away if the given CPU is idle. Consequently, it is possible to stop
+the scheduler tick entirely on idle CPUs in principle, even though that may not
+always be worth the effort.
+
+Whether or not it makes sense to stop the scheduler tick in the idle loop
+depends on what is expected by the governor. First, if there is another
+(non-tick) timer due to trigger within the tick range, stopping the tick clearly
+would be a waste of time, even though the timer hardware may not need to be
+reprogrammed in that case. Second, if the governor is expecting a non-timer
+wakeup within the tick range, stopping the tick is not necessary and it may even
+be harmful. Namely, in that case the governor will select an idle state with
+the target residency within the time until the expected wakeup, so that state is
+going to be relatively shallow. The governor really cannot select a deep idle
+state then, as that would contradict its own expectation of a wakeup in short
+order. Now, if the wakeup really occurs shortly, stopping the tick would be a
+waste of time and in this case the timer hardware would need to be reprogrammed,
+which is expensive. On the other hand, if the tick is stopped and the wakeup
+does not occur any time soon, the hardware may spend indefinite amount of time
+in the shallow idle state selected by the governor, which will be a waste of
+energy. Hence, if the governor is expecting a wakeup of any kind within the
+tick range, it is better to allow the tick trigger. Otherwise, however, the
+governor will select a relatively deep idle state, so the tick should be stopped
+so that it does not wake up the CPU too early.
+
+In any case, the governor knows what it is expecting and the decision on whether
+or not to stop the scheduler tick belongs to it. Still, if the tick has been
+stopped already (in one of the previous iterations of the loop), it is better
+to leave it as is and the governor needs to take that into account.
+
+The kernel can be configured to disable stopping the scheduler tick in the idle
+loop altogether. That can be done through the build-time configuration of it
+(by unsetting the ``CONFIG_NO_HZ_IDLE`` configuration option) or by passing
+``nohz=off`` to it in the command line. In both cases, as the stopping of the
+scheduler tick is disabled, the governor's decisions regarding it are simply
+ignored by the idle loop code and the tick is never stopped.
+
+The systems that run kernels configured to allow the scheduler tick to be
+stopped on idle CPUs are referred to as *tickless* systems and they are
+generally regarded as more energy-efficient than the systems running kernels in
+which the tick cannot be stopped. If the given system is tickless, it will use
+the ``menu`` governor by default and if it is not tickless, the default
+``CPUIdle`` governor on it will be ``ladder``.
+
+
+.. _menu-gov:
+
+The ``menu`` Governor
+=====================
+
+The ``menu`` governor is the default ``CPUIdle`` governor for tickless systems.
+It is quite complex, but the basic principle of its design is straightforward.
+Namely, when invoked to select an idle state for a CPU (i.e. an idle state that
+the CPU will ask the processor hardware to enter), it attempts to predict the
+idle duration and uses the predicted value for idle state selection.
+
+It first obtains the time until the closest timer event with the assumption
+that the scheduler tick will be stopped. That time, referred to as the *sleep
+length* in what follows, is the upper bound on the time before the next CPU
+wakeup. It is used to determine the sleep length range, which in turn is needed
+to get the sleep length correction factor.
+
+The ``menu`` governor maintains two arrays of sleep length correction factors.
+One of them is used when tasks previously running on the given CPU are waiting
+for some I/O operations to complete and the other one is used when that is not
+the case. Each array contains several correction factor values that correspond
+to different sleep length ranges organized so that each range represented in the
+array is approximately 10 times wider than the previous one.
+
+The correction factor for the given sleep length range (determined before
+selecting the idle state for the CPU) is updated after the CPU has been woken
+up and the closer the sleep length is to the observed idle duration, the closer
+to 1 the correction factor becomes (it must fall between 0 and 1 inclusive).
+The sleep length is multiplied by the correction factor for the range that it
+falls into to obtain the first approximation of the predicted idle duration.
+
+Next, the governor uses a simple pattern recognition algorithm to refine its
+idle duration prediction. Namely, it saves the last 8 observed idle duration
+values and, when predicting the idle duration next time, it computes the average
+and variance of them. If the variance is small (smaller than 400 square
+milliseconds) or it is small relative to the average (the average is greater
+that 6 times the standard deviation), the average is regarded as the "typical
+interval" value. Otherwise, the longest of the saved observed idle duration
+values is discarded and the computation is repeated for the remaining ones.
+Again, if the variance of them is small (in the above sense), the average is
+taken as the "typical interval" value and so on, until either the "typical
+interval" is determined or too many data points are disregarded, in which case
+the "typical interval" is assumed to equal "infinity" (the maximum unsigned
+integer value). The "typical interval" computed this way is compared with the
+sleep length multiplied by the correction factor and the minimum of the two is
+taken as the predicted idle duration.
+
+Then, the governor computes an extra latency limit to help "interactive"
+workloads. It uses the observation that if the exit latency of the selected
+idle state is comparable with the predicted idle duration, the total time spent
+in that state probably will be very short and the amount of energy to save by
+entering it will be relatively small, so likely it is better to avoid the
+overhead related to entering that state and exiting it. Thus selecting a
+shallower state is likely to be a better option then. The first approximation
+of the extra latency limit is the predicted idle duration itself which
+additionally is divided by a value depending on the number of tasks that
+previously ran on the given CPU and now they are waiting for I/O operations to
+complete. The result of that division is compared with the latency limit coming
+from the power management quality of service, or `PM QoS <cpu-pm-qos_>`_,
+framework and the minimum of the two is taken as the limit for the idle states'
+exit latency.
+
+Now, the governor is ready to walk the list of idle states and choose one of
+them. For this purpose, it compares the target residency of each state with
+the predicted idle duration and the exit latency of it with the computed latency
+limit. It selects the state with the target residency closest to the predicted
+idle duration, but still below it, and exit latency that does not exceed the
+limit.
+
+In the final step the governor may still need to refine the idle state selection
+if it has not decided to `stop the scheduler tick <idle-cpus-and-tick_>`_. That
+happens if the idle duration predicted by it is less than the tick period and
+the tick has not been stopped already (in a previous iteration of the idle
+loop). Then, the sleep length used in the previous computations may not reflect
+the real time until the closest timer event and if it really is greater than
+that time, the governor may need to select a shallower state with a suitable
+target residency.
+
+
+.. _teo-gov:
+
+The Timer Events Oriented (TEO) Governor
+========================================
+
+The timer events oriented (TEO) governor is an alternative ``CPUIdle`` governor
+for tickless systems. It follows the same basic strategy as the ``menu`` `one
+<menu-gov_>`_: it always tries to find the deepest idle state suitable for the
+given conditions. However, it applies a different approach to that problem.
+
+First, it does not use sleep length correction factors, but instead it attempts
+to correlate the observed idle duration values with the available idle states
+and use that information to pick up the idle state that is most likely to
+"match" the upcoming CPU idle interval. Second, it does not take the tasks
+that were running on the given CPU in the past and are waiting on some I/O
+operations to complete now at all (there is no guarantee that they will run on
+the same CPU when they become runnable again) and the pattern detection code in
+it avoids taking timer wakeups into account. It also only uses idle duration
+values less than the current time till the closest timer (with the scheduler
+tick excluded) for that purpose.
+
+Like in the ``menu`` governor `case <menu-gov_>`_, the first step is to obtain
+the *sleep length*, which is the time until the closest timer event with the
+assumption that the scheduler tick will be stopped (that also is the upper bound
+on the time until the next CPU wakeup). That value is then used to preselect an
+idle state on the basis of three metrics maintained for each idle state provided
+by the ``CPUIdle`` driver: ``hits``, ``misses`` and ``early_hits``.
+
+The ``hits`` and ``misses`` metrics measure the likelihood that a given idle
+state will "match" the observed (post-wakeup) idle duration if it "matches" the
+sleep length. They both are subject to decay (after a CPU wakeup) every time
+the target residency of the idle state corresponding to them is less than or
+equal to the sleep length and the target residency of the next idle state is
+greater than the sleep length (that is, when the idle state corresponding to
+them "matches" the sleep length). The ``hits`` metric is increased if the
+former condition is satisfied and the target residency of the given idle state
+is less than or equal to the observed idle duration and the target residency of
+the next idle state is greater than the observed idle duration at the same time
+(that is, it is increased when the given idle state "matches" both the sleep
+length and the observed idle duration). In turn, the ``misses`` metric is
+increased when the given idle state "matches" the sleep length only and the
+observed idle duration is too short for its target residency.
+
+The ``early_hits`` metric measures the likelihood that a given idle state will
+"match" the observed (post-wakeup) idle duration if it does not "match" the
+sleep length. It is subject to decay on every CPU wakeup and it is increased
+when the idle state corresponding to it "matches" the observed (post-wakeup)
+idle duration and the target residency of the next idle state is less than or
+equal to the sleep length (i.e. the idle state "matching" the sleep length is
+deeper than the given one).
+
+The governor walks the list of idle states provided by the ``CPUIdle`` driver
+and finds the last (deepest) one with the target residency less than or equal
+to the sleep length. Then, the ``hits`` and ``misses`` metrics of that idle
+state are compared with each other and it is preselected if the ``hits`` one is
+greater (which means that that idle state is likely to "match" the observed idle
+duration after CPU wakeup). If the ``misses`` one is greater, the governor
+preselects the shallower idle state with the maximum ``early_hits`` metric
+(or if there are multiple shallower idle states with equal ``early_hits``
+metric which also is the maximum, the shallowest of them will be preselected).
+[If there is a wakeup latency constraint coming from the `PM QoS framework
+<cpu-pm-qos_>`_ which is hit before reaching the deepest idle state with the
+target residency within the sleep length, the deepest idle state with the exit
+latency within the constraint is preselected without consulting the ``hits``,
+``misses`` and ``early_hits`` metrics.]
+
+Next, the governor takes several idle duration values observed most recently
+into consideration and if at least a half of them are greater than or equal to
+the target residency of the preselected idle state, that idle state becomes the
+final candidate to ask for. Otherwise, the average of the most recent idle
+duration values below the target residency of the preselected idle state is
+computed and the governor walks the idle states shallower than the preselected
+one and finds the deepest of them with the target residency within that average.
+That idle state is then taken as the final candidate to ask for.
+
+Still, at this point the governor may need to refine the idle state selection if
+it has not decided to `stop the scheduler tick <idle-cpus-and-tick_>`_. That
+generally happens if the target residency of the idle state selected so far is
+less than the tick period and the tick has not been stopped already (in a
+previous iteration of the idle loop). Then, like in the ``menu`` governor
+`case <menu-gov_>`_, the sleep length used in the previous computations may not
+reflect the real time until the closest timer event and if it really is greater
+than that time, a shallower state with a suitable target residency may need to
+be selected.
+
+
+.. _idle-states-representation:
+
+Representation of Idle States
+=============================
+
+For the CPU idle time management purposes all of the physical idle states
+supported by the processor have to be represented as a one-dimensional array of
+|struct cpuidle_state| objects each allowing an individual (logical) CPU to ask
+the processor hardware to enter an idle state of certain properties. If there
+is a hierarchy of units in the processor, one |struct cpuidle_state| object can
+cover a combination of idle states supported by the units at different levels of
+the hierarchy. In that case, the `target residency and exit latency parameters
+of it <idle-loop_>`_, must reflect the properties of the idle state at the
+deepest level (i.e. the idle state of the unit containing all of the other
+units).
+
+For example, take a processor with two cores in a larger unit referred to as
+a "module" and suppose that asking the hardware to enter a specific idle state
+(say "X") at the "core" level by one core will trigger the module to try to
+enter a specific idle state of its own (say "MX") if the other core is in idle
+state "X" already. In other words, asking for idle state "X" at the "core"
+level gives the hardware a license to go as deep as to idle state "MX" at the
+"module" level, but there is no guarantee that this is going to happen (the core
+asking for idle state "X" may just end up in that state by itself instead).
+Then, the target residency of the |struct cpuidle_state| object representing
+idle state "X" must reflect the minimum time to spend in idle state "MX" of
+the module (including the time needed to enter it), because that is the minimum
+time the CPU needs to be idle to save any energy in case the hardware enters
+that state. Analogously, the exit latency parameter of that object must cover
+the exit time of idle state "MX" of the module (and usually its entry time too),
+because that is the maximum delay between a wakeup signal and the time the CPU
+will start to execute the first new instruction (assuming that both cores in the
+module will always be ready to execute instructions as soon as the module
+becomes operational as a whole).
+
+There are processors without direct coordination between different levels of the
+hierarchy of units inside them, however. In those cases asking for an idle
+state at the "core" level does not automatically affect the "module" level, for
+example, in any way and the ``CPUIdle`` driver is responsible for the entire
+handling of the hierarchy. Then, the definition of the idle state objects is
+entirely up to the driver, but still the physical properties of the idle state
+that the processor hardware finally goes into must always follow the parameters
+used by the governor for idle state selection (for instance, the actual exit
+latency of that idle state must not exceed the exit latency parameter of the
+idle state object selected by the governor).
+
+In addition to the target residency and exit latency idle state parameters
+discussed above, the objects representing idle states each contain a few other
+parameters describing the idle state and a pointer to the function to run in
+order to ask the hardware to enter that state. Also, for each
+|struct cpuidle_state| object, there is a corresponding
+:c:type:`struct cpuidle_state_usage <cpuidle_state_usage>` one containing usage
+statistics of the given idle state. That information is exposed by the kernel
+via ``sysfs``.
+
+For each CPU in the system, there is a :file:`/sys/devices/system/cpu<N>/cpuidle/`
+directory in ``sysfs``, where the number ``<N>`` is assigned to the given
+CPU at the initialization time. That directory contains a set of subdirectories
+called :file:`state0`, :file:`state1` and so on, up to the number of idle state
+objects defined for the given CPU minus one. Each of these directories
+corresponds to one idle state object and the larger the number in its name, the
+deeper the (effective) idle state represented by it. Each of them contains
+a number of files (attributes) representing the properties of the idle state
+object corresponding to it, as follows:
+
+``above``
+ Total number of times this idle state had been asked for, but the
+ observed idle duration was certainly too short to match its target
+ residency.
+
+``below``
+ Total number of times this idle state had been asked for, but cerainly
+ a deeper idle state would have been a better match for the observed idle
+ duration.
+
+``desc``
+ Description of the idle state.
+
+``disable``
+ Whether or not this idle state is disabled.
+
+``latency``
+ Exit latency of the idle state in microseconds.
+
+``name``
+ Name of the idle state.
+
+``power``
+ Power drawn by hardware in this idle state in milliwatts (if specified,
+ 0 otherwise).
+
+``residency``
+ Target residency of the idle state in microseconds.
+
+``time``
+ Total time spent in this idle state by the given CPU (as measured by the
+ kernel) in microseconds.
+
+``usage``
+ Total number of times the hardware has been asked by the given CPU to
+ enter this idle state.
+
+The :file:`desc` and :file:`name` files both contain strings. The difference
+between them is that the name is expected to be more concise, while the
+description may be longer and it may contain white space or special characters.
+The other files listed above contain integer numbers.
+
+The :file:`disable` attribute is the only writeable one. If it contains 1, the
+given idle state is disabled for this particular CPU, which means that the
+governor will never select it for this particular CPU and the ``CPUIdle``
+driver will never ask the hardware to enter it for that CPU as a result.
+However, disabling an idle state for one CPU does not prevent it from being
+asked for by the other CPUs, so it must be disabled for all of them in order to
+never be asked for by any of them. [Note that, due to the way the ``ladder``
+governor is implemented, disabling an idle state prevents that governor from
+selecting any idle states deeper than the disabled one too.]
+
+If the :file:`disable` attribute contains 0, the given idle state is enabled for
+this particular CPU, but it still may be disabled for some or all of the other
+CPUs in the system at the same time. Writing 1 to it causes the idle state to
+be disabled for this particular CPU and writing 0 to it allows the governor to
+take it into consideration for the given CPU and the driver to ask for it,
+unless that state was disabled globally in the driver (in which case it cannot
+be used at all).
+
+The :file:`power` attribute is not defined very well, especially for idle state
+objects representing combinations of idle states at different levels of the
+hierarchy of units in the processor, and it generally is hard to obtain idle
+state power numbers for complex hardware, so :file:`power` often contains 0 (not
+available) and if it contains a nonzero number, that number may not be very
+accurate and it should not be relied on for anything meaningful.
+
+The number in the :file:`time` file generally may be greater than the total time
+really spent by the given CPU in the given idle state, because it is measured by
+the kernel and it may not cover the cases in which the hardware refused to enter
+this idle state and entered a shallower one instead of it (or even it did not
+enter any idle state at all). The kernel can only measure the time span between
+asking the hardware to enter an idle state and the subsequent wakeup of the CPU
+and it cannot say what really happened in the meantime at the hardware level.
+Moreover, if the idle state object in question represents a combination of idle
+states at different levels of the hierarchy of units in the processor,
+the kernel can never say how deep the hardware went down the hierarchy in any
+particular case. For these reasons, the only reliable way to find out how
+much time has been spent by the hardware in different idle states supported by
+it is to use idle state residency counters in the hardware, if available.
+
+
+.. _cpu-pm-qos:
+
+Power Management Quality of Service for CPUs
+============================================
+
+The power management quality of service (PM QoS) framework in the Linux kernel
+allows kernel code and user space processes to set constraints on various
+energy-efficiency features of the kernel to prevent performance from dropping
+below a required level. The PM QoS constraints can be set globally, in
+predefined categories referred to as PM QoS classes, or against individual
+devices.
+
+CPU idle time management can be affected by PM QoS in two ways, through the
+global constraint in the ``PM_QOS_CPU_DMA_LATENCY`` class and through the
+resume latency constraints for individual CPUs. Kernel code (e.g. device
+drivers) can set both of them with the help of special internal interfaces
+provided by the PM QoS framework. User space can modify the former by opening
+the :file:`cpu_dma_latency` special device file under :file:`/dev/` and writing
+a binary value (interpreted as a signed 32-bit integer) to it. In turn, the
+resume latency constraint for a CPU can be modified by user space by writing a
+string (representing a signed 32-bit integer) to the
+:file:`power/pm_qos_resume_latency_us` file under
+:file:`/sys/devices/system/cpu/cpu<N>/` in ``sysfs``, where the CPU number
+``<N>`` is allocated at the system initialization time. Negative values
+will be rejected in both cases and, also in both cases, the written integer
+number will be interpreted as a requested PM QoS constraint in microseconds.
+
+The requested value is not automatically applied as a new constraint, however,
+as it may be less restrictive (greater in this particular case) than another
+constraint previously requested by someone else. For this reason, the PM QoS
+framework maintains a list of requests that have been made so far in each
+global class and for each device, aggregates them and applies the effective
+(minimum in this particular case) value as the new constraint.
+
+In fact, opening the :file:`cpu_dma_latency` special device file causes a new
+PM QoS request to be created and added to the priority list of requests in the
+``PM_QOS_CPU_DMA_LATENCY`` class and the file descriptor coming from the
+"open" operation represents that request. If that file descriptor is then
+used for writing, the number written to it will be associated with the PM QoS
+request represented by it as a new requested constraint value. Next, the
+priority list mechanism will be used to determine the new effective value of
+the entire list of requests and that effective value will be set as a new
+constraint. Thus setting a new requested constraint value will only change the
+real constraint if the effective "list" value is affected by it. In particular,
+for the ``PM_QOS_CPU_DMA_LATENCY`` class it only affects the real constraint if
+it is the minimum of the requested constraints in the list. The process holding
+a file descriptor obtained by opening the :file:`cpu_dma_latency` special device
+file controls the PM QoS request associated with that file descriptor, but it
+controls this particular PM QoS request only.
+
+Closing the :file:`cpu_dma_latency` special device file or, more precisely, the
+file descriptor obtained while opening it, causes the PM QoS request associated
+with that file descriptor to be removed from the ``PM_QOS_CPU_DMA_LATENCY``
+class priority list and destroyed. If that happens, the priority list mechanism
+will be used, again, to determine the new effective value for the whole list
+and that value will become the new real constraint.
+
+In turn, for each CPU there is only one resume latency PM QoS request
+associated with the :file:`power/pm_qos_resume_latency_us` file under
+:file:`/sys/devices/system/cpu/cpu<N>/` in ``sysfs`` and writing to it causes
+this single PM QoS request to be updated regardless of which user space
+process does that. In other words, this PM QoS request is shared by the entire
+user space, so access to the file associated with it needs to be arbitrated
+to avoid confusion. [Arguably, the only legitimate use of this mechanism in
+practice is to pin a process to the CPU in question and let it use the
+``sysfs`` interface to control the resume latency constraint for it.] It
+still only is a request, however. It is a member of a priority list used to
+determine the effective value to be set as the resume latency constraint for the
+CPU in question every time the list of requests is updated this way or another
+(there may be other requests coming from kernel code in that list).
+
+CPU idle time governors are expected to regard the minimum of the global
+effective ``PM_QOS_CPU_DMA_LATENCY`` class constraint and the effective
+resume latency constraint for the given CPU as the upper limit for the exit
+latency of the idle states they can select for that CPU. They should never
+select any idle states with exit latency beyond that limit.
+
+
+Idle States Control Via Kernel Command Line
+===========================================
+
+In addition to the ``sysfs`` interface allowing individual idle states to be
+`disabled for individual CPUs <idle-states-representation_>`_, there are kernel
+command line parameters affecting CPU idle time management.
+
+The ``cpuidle.off=1`` kernel command line option can be used to disable the
+CPU idle time management entirely. It does not prevent the idle loop from
+running on idle CPUs, but it prevents the CPU idle time governors and drivers
+from being invoked. If it is added to the kernel command line, the idle loop
+will ask the hardware to enter idle states on idle CPUs via the CPU architecture
+support code that is expected to provide a default mechanism for this purpose.
+That default mechanism usually is the least common denominator for all of the
+processors implementing the architecture (i.e. CPU instruction set) in question,
+however, so it is rather crude and not very energy-efficient. For this reason,
+it is not recommended for production use.
+
+The ``cpuidle.governor=`` kernel command line switch allows the ``CPUIdle``
+governor to use to be specified. It has to be appended with a string matching
+the name of an available governor (e.g. ``cpuidle.governor=menu``) and that
+governor will be used instead of the default one. It is possible to force
+the ``menu`` governor to be used on the systems that use the ``ladder`` governor
+by default this way, for example.
+
+The other kernel command line parameters controlling CPU idle time management
+described below are only relevant for the *x86* architecture and some of
+them affect Intel processors only.
+
+The *x86* architecture support code recognizes three kernel command line
+options related to CPU idle time management: ``idle=poll``, ``idle=halt``,
+and ``idle=nomwait``. The first two of them disable the ``acpi_idle`` and
+``intel_idle`` drivers altogether, which effectively causes the entire
+``CPUIdle`` subsystem to be disabled and makes the idle loop invoke the
+architecture support code to deal with idle CPUs. How it does that depends on
+which of the two parameters is added to the kernel command line. In the
+``idle=halt`` case, the architecture support code will use the ``HLT``
+instruction of the CPUs (which, as a rule, suspends the execution of the program
+and causes the hardware to attempt to enter the shallowest available idle state)
+for this purpose, and if ``idle=poll`` is used, idle CPUs will execute a
+more or less ``lightweight'' sequence of instructions in a tight loop. [Note
+that using ``idle=poll`` is somewhat drastic in many cases, as preventing idle
+CPUs from saving almost any energy at all may not be the only effect of it.
+For example, on Intel hardware it effectively prevents CPUs from using
+P-states (see |cpufreq|) that require any number of CPUs in a package to be
+idle, so it very well may hurt single-thread computations performance as well as
+energy-efficiency. Thus using it for performance reasons may not be a good idea
+at all.]
+
+The ``idle=nomwait`` option disables the ``intel_idle`` driver and causes
+``acpi_idle`` to be used (as long as all of the information needed by it is
+there in the system's ACPI tables), but it is not allowed to use the
+``MWAIT`` instruction of the CPUs to ask the hardware to enter idle states.
+
+In addition to the architecture-level kernel command line options affecting CPU
+idle time management, there are parameters affecting individual ``CPUIdle``
+drivers that can be passed to them via the kernel command line. Specifically,
+the ``intel_idle.max_cstate=<n>`` and ``processor.max_cstate=<n>`` parameters,
+where ``<n>`` is an idle state index also used in the name of the given
+state's directory in ``sysfs`` (see
+`Representation of Idle States <idle-states-representation_>`_), causes the
+``intel_idle`` and ``acpi_idle`` drivers, respectively, to discard all of the
+idle states deeper than idle state ``<n>``. In that case, they will never ask
+for any of those idle states or expose them to the governor. [The behavior of
+the two drivers is different for ``<n>`` equal to ``0``. Adding
+``intel_idle.max_cstate=0`` to the kernel command line disables the
+``intel_idle`` driver and allows ``acpi_idle`` to be used, whereas
+``processor.max_cstate=0`` is equivalent to ``processor.max_cstate=1``.
+Also, the ``acpi_idle`` driver is part of the ``processor`` kernel module that
+can be loaded separately and ``max_cstate=<n>`` can be passed to it as a module
+parameter when it is loaded.]

+The kernel will mark itself as 'tainted' when something occurs that might be
+relevant later when investigating problems. Don't worry too much about this,
+most of the time it's not a problem to run a tainted kernel; the information is
+mainly of interest once someone wants to investigate some problem, as its real
+cause might be the event that got the kernel tainted. That's why bug reports
+from tainted kernels will often be ignored by developers, hence try to reproduce
+problems with an untainted kernel.
+
+Note the kernel will remain tainted even after you undo what caused the taint
+(i.e. unload a proprietary kernel module), to indicate the kernel remains not
+trustworthy. That's also why the kernel will print the tainted state when it
+notices an internal problem (a 'kernel bug'), a recoverable error
+('kernel oops') or a non-recoverable error ('kernel panic') and writes debug
+information about this to the logs ``dmesg`` outputs. It's also possible to
+check the tainted state at runtime through a file in ``/proc/``.
+
+
+Tainted flag in bugs, oops or panics messages
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You find the tainted state near the top in a line starting with 'CPU:'; if or
+why the kernel was tainted is shown after the Process ID ('PID:') and a shortened
+name of the command ('Comm:') that triggered the event::
+
+ BUG: unable to handle kernel NULL pointer dereference at 0000000000000000
+ Oops: 0002 [#1] SMP PTI
+ CPU: 0 PID: 4424 Comm: insmod Tainted: P W O 4.20.0-0.rc6.fc30 #1
+ Hardware name: Red Hat KVM, BIOS 0.5.1 01/01/2011
+ RIP: 0010:my_oops_init+0x13/0x1000 [kpanic]
+ [...]
+
+You'll find a 'Not tainted: ' there if the kernel was not tainted at the
+time of the event; if it was, then it will print 'Tainted: ' and characters
+either letters or blanks. In above example it looks like this::
+
+ Tainted: P W O
+
+The meaning of those characters is explained in the table below. In tis case
+the kernel got tainted earlier because a proprietary Module (``P``) was loaded,
+a warning occurred (``W``), and an externally-built module was loaded (``O``).
+To decode other letters use the table below.
+
+
+Decoding tainted state at runtime
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+At runtime, you can query the tainted state by reading
+``cat /proc/sys/kernel/tainted``. If that returns ``0``, the kernel is not
+tainted; any other number indicates the reasons why it is. The easiest way to
+decode that number is the script ``tools/debugging/kernel-chktaint``, which your
+distribution might ship as part of a package called ``linux-tools`` or
+``kernel-tools``; if it doesn't you can download the script from
+`git.kernel.org <https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/plain/tools/debugging/kernel-chktaint>`_
+and execute it with ``sh kernel-chktaint``, which would print something like
+this on the machine that had the statements in the logs that were quoted earlier::
+
+ Kernel is Tainted for following reasons:
+ * Proprietary module was loaded (#0)
+ * Kernel issued warning (#9)
+ * Externally-built ('out-of-tree') module was loaded (#12)
+ See Documentation/admin-guide/tainted-kernels.rst in the the Linux kernel or
+ https://www.kernel.org/doc/html/latest/admin-guide/tainted-kernels.html for
+ a more details explanation of the various taint flags.
+ Raw taint value as int/string: 4609/'P W O '
+
+You can try to decode the number yourself. That's easy if there was only one
+reason that got your kernel tainted, as in this case you can find the number
+with the table below. If there were multiple reasons you need to decode the
+number, as it is a bitfield, where each bit indicates the absence or presence of
+a particular type of taint. It's best to leave that to the aforementioned
+script, but if you need something quick you can use this shell command to check
+which bits are set::
+
+ $ for i in $(seq 18); do echo $(($i-1)) $(($(cat /proc/sys/kernel/tainted)>>($i-1)&1));done

+Pointer authentication in AArch64 Linux
+=======================================
+
+Author: Mark Rutland <mark.rutland@arm.com>
+Date: 2017-07-19
+
+This document briefly describes the provision of pointer authentication
+functionality in AArch64 Linux.
+
+
+Architecture overview
+---------------------
+
+The ARMv8.3 Pointer Authentication extension adds primitives that can be
+used to mitigate certain classes of attack where an attacker can corrupt
+the contents of some memory (e.g. the stack).
+
+The extension uses a Pointer Authentication Code (PAC) to determine
+whether pointers have been modified unexpectedly. A PAC is derived from
+a pointer, another value (such as the stack pointer), and a secret key
+held in system registers.
+
+The extension adds instructions to insert a valid PAC into a pointer,
+and to verify/remove the PAC from a pointer. The PAC occupies a number
+of high-order bits of the pointer, which varies dependent on the
+configured virtual address size and whether pointer tagging is in use.
+
+A subset of these instructions have been allocated from the HINT
+encoding space. In the absence of the extension (or when disabled),
+these instructions behave as NOPs. Applications and libraries using
+these instructions operate correctly regardless of the presence of the
+extension.
+
+The extension provides five separate keys to generate PACs - two for
+instruction addresses (APIAKey, APIBKey), two for data addresses
+(APDAKey, APDBKey), and one for generic authentication (APGAKey).
+
+
+Basic support
+-------------
+
+When CONFIG_ARM64_PTR_AUTH is selected, and relevant HW support is
+present, the kernel will assign random key values to each process at
+exec*() time. The keys are shared by all threads within the process, and
+are preserved across fork().
+
+Presence of address authentication functionality is advertised via
+HWCAP_PACA, and generic authentication functionality via HWCAP_PACG.
+
+The number of bits that the PAC occupies in a pointer is 55 minus the
+virtual address size configured by the kernel. For example, with a
+virtual address size of 48, the PAC is 7 bits wide.
+
+Recent versions of GCC can compile code with APIAKey-based return
+address protection when passed the -msign-return-address option. This
+uses instructions in the HINT space (unless -march=armv8.3-a or higher
+is also passed), and such code can run on systems without the pointer
+authentication extension.
+
+In addition to exec(), keys can also be reinitialized to random values
+using the PR_PAC_RESET_KEYS prctl. A bitmask of PR_PAC_APIAKEY,
+PR_PAC_APIBKEY, PR_PAC_APDAKEY, PR_PAC_APDBKEY and PR_PAC_APGAKEY
+specifies which keys are to be reinitialized; specifying 0 means "all
+keys".
+
+
+Debugging
+---------
+
+When CONFIG_ARM64_PTR_AUTH is selected, and HW support for address
+authentication is present, the kernel will expose the position of TTBR0
+PAC bits in the NT_ARM_PAC_MASK regset (struct user_pac_mask), which
+userspace can acquire via PTRACE_GETREGSET.
+
+The regset is exposed only when HWCAP_PACA is set. Separate masks are
+exposed for data pointers and instruction pointers, as the set of PAC
+bits can vary between the two. Note that the masks apply to TTBR0
+addresses, and are not valid to apply to TTBR1 addresses (e.g. kernel
+pointers).
+
+Additionally, when CONFIG_CHECKPOINT_RESTORE is also set, the kernel
+will expose the NT_ARM_PACA_KEYS and NT_ARM_PACG_KEYS regsets (struct
+user_pac_address_keys and struct user_pac_generic_keys). These can be
+used to get and set the keys for a thread.
+
+
+Virtualization
+--------------
+
+Pointer authentication is not currently supported in KVM guests. KVM
+will mask the feature bits from ID_AA64ISAR1_EL1, and attempted use of
+the feature will result in an UNDEFINED exception being injected into
+the guest.

-3.2.5 Generic request command tagging
-
-3.2.5.1 Tag helpers
-
-Block now offers some simple generic functionality to help support command
-queueing (typically known as tagged command queueing), ie manage more than
-one outstanding command on a queue at any given time.
-
- blk_queue_init_tags(struct request_queue *q, int depth)
-
- Initialize internal command tagging structures for a maximum
- depth of 'depth'.
-
- blk_queue_free_tags((struct request_queue *q)
-
- Teardown tag info associated with the queue. This will be done
- automatically by block if blk_queue_cleanup() is called on a queue
- that is using tagging.
-
-The above are initialization and exit management, the main helpers during
-normal operations are:
-
- blk_queue_start_tag(struct request_queue *q, struct request *rq)
-
- Start tagged operation for this request. A free tag number between
- 0 and 'depth' is assigned to the request (rq->tag holds this number),
- and 'rq' is added to the internal tag management. If the maximum depth
- for this queue is already achieved (or if the tag wasn't started for
- some other reason), 1 is returned. Otherwise 0 is returned.
-
- blk_queue_end_tag(struct request_queue *q, struct request *rq)
-
- End tagged operation on this request. 'rq' is removed from the internal
- book keeping structures.
-
-To minimize struct request and queue overhead, the tag helpers utilize some
-of the same request members that are used for normal request queue management.
-This means that a request cannot both be an active tag and be on the queue
-list at the same time. blk_queue_start_tag() will remove the request, but
-the driver must remember to call blk_queue_end_tag() before signalling
-completion of the request to the block layer. This means ending tag
-operations before calling end_that_request_last()! For an example of a user
-of these helpers, see the IDE tagged command queueing support.
-
-3.2.5.2 Tag info
-
-Some block functions exist to query current tag status or to go from a
-tag number to the associated request. These are, in no particular order:
-
- blk_queue_tagged(q)
-
- Returns 1 if the queue 'q' is using tagging, 0 if not.
-
- blk_queue_tag_request(q, tag)
-
- Returns a pointer to the request associated with tag 'tag'.
-
- blk_queue_tag_depth(q)
-
- Return current queue depth.
-
- blk_queue_tag_queue(q)
-
- Returns 1 if the queue can accept a new queued command, 0 if we are
- at the maximum depth already.
-
- blk_queue_rq_tagged(rq)
-
- Returns 1 if the request 'rq' is tagged.
-
-3.2.5.2 Internal structure
-
-Internally, block manages tags in the blk_queue_tag structure:
-
- struct blk_queue_tag {
- struct request **tag_index; /* array or pointers to rq */
- unsigned long *tag_map; /* bitmap of free tags */
- struct list_head busy_list; /* fifo list of busy tags */
- int busy; /* queue depth */
- int max_depth; /* max queue depth */
- };
-
-Most of the above is simple and straight forward, however busy_list may need
-a bit of explaining. Normally we don't care too much about request ordering,
-but in the event of any barrier requests in the tag queue we need to ensure
-that requests are restarted in the order they were queue.

-CFQ (Complete Fairness Queueing)
-===============================
-
-The main aim of CFQ scheduler is to provide a fair allocation of the disk
-I/O bandwidth for all the processes which requests an I/O operation.
-
-CFQ maintains the per process queue for the processes which request I/O
-operation(synchronous requests). In case of asynchronous requests, all the
-requests from all the processes are batched together according to their
-process's I/O priority.
-
-CFQ ioscheduler tunables
-========================
-
-slice_idle
-----------
-This specifies how long CFQ should idle for next request on certain cfq queues
-(for sequential workloads) and service trees (for random workloads) before
-queue is expired and CFQ selects next queue to dispatch from.
-
-By default slice_idle is a non-zero value. That means by default we idle on
-queues/service trees. This can be very helpful on highly seeky media like
-single spindle SATA/SAS disks where we can cut down on overall number of
-seeks and see improved throughput.
-
-Setting slice_idle to 0 will remove all the idling on queues/service tree
-level and one should see an overall improved throughput on faster storage
-devices like multiple SATA/SAS disks in hardware RAID configuration. The down
-side is that isolation provided from WRITES also goes down and notion of
-IO priority becomes weaker.
-
-So depending on storage and workload, it might be useful to set slice_idle=0.
-In general I think for SATA/SAS disks and software RAID of SATA/SAS disks
-keeping slice_idle enabled should be useful. For any configurations where
-there are multiple spindles behind single LUN (Host based hardware RAID
-controller or for storage arrays), setting slice_idle=0 might end up in better
-throughput and acceptable latencies.
-
-back_seek_max
--------------
-This specifies, given in Kbytes, the maximum "distance" for backward seeking.
-The distance is the amount of space from the current head location to the
-sectors that are backward in terms of distance.
-
-This parameter allows the scheduler to anticipate requests in the "backward"
-direction and consider them as being the "next" if they are within this
-distance from the current head location.
-
-back_seek_penalty
------------------
-This parameter is used to compute the cost of backward seeking. If the
-backward distance of request is just 1/back_seek_penalty from a "front"
-request, then the seeking cost of two requests is considered equivalent.
-
-So scheduler will not bias toward one or the other request (otherwise scheduler
-will bias toward front request). Default value of back_seek_penalty is 2.
-
-fifo_expire_async
------------------
-This parameter is used to set the timeout of asynchronous requests. Default
-value of this is 248ms.
-
-fifo_expire_sync
-----------------
-This parameter is used to set the timeout of synchronous requests. Default
-value of this is 124ms. In case to favor synchronous requests over asynchronous
-one, this value should be decreased relative to fifo_expire_async.
-
-group_idle
------------
-This parameter forces idling at the CFQ group level instead of CFQ
-queue level. This was introduced after a bottleneck was observed
-in higher end storage due to idle on sequential queue and allow dispatch
-from a single queue. The idea with this parameter is that it can be run with
-slice_idle=0 and group_idle=8, so that idling does not happen on individual
-queues in the group but happens overall on the group and thus still keeps the
-IO controller working.
-Not idling on individual queues in the group will dispatch requests from
-multiple queues in the group at the same time and achieve higher throughput
-on higher end storage.
-
-Default value for this parameter is 8ms.
-
-low_latency
------------
-This parameter is used to enable/disable the low latency mode of the CFQ
-scheduler. If enabled, CFQ tries to recompute the slice time for each process
-based on the target_latency set for the system. This favors fairness over
-throughput. Disabling low latency (setting it to 0) ignores target latency,
-allowing each process in the system to get a full time slice.
-
-By default low latency mode is enabled.
-
-target_latency
---------------
-This parameter is used to calculate the time slice for a process if cfq's
-latency mode is enabled. It will ensure that sync requests have an estimated
-latency. But if sequential workload is higher(e.g. sequential read),
-then to meet the latency constraints, throughput may decrease because of less
-time for each process to issue I/O request before the cfq queue is switched.
-
-Though this can be overcome by disabling the latency_mode, it may increase
-the read latency for some applications. This parameter allows for changing
-target_latency through the sysfs interface which can provide the balanced
-throughput and read latency.
-
-Default value for target_latency is 300ms.
-
-slice_async
------------
-This parameter is same as of slice_sync but for asynchronous queue. The
-default value is 40ms.
-
-slice_async_rq
---------------
-This parameter is used to limit the dispatching of asynchronous request to
-device request queue in queue's slice time. The maximum number of request that
-are allowed to be dispatched also depends upon the io priority. Default value
-for this is 2.
-
-slice_sync
-----------
-When a queue is selected for execution, the queues IO requests are only
-executed for a certain amount of time(time_slice) before switching to another
-queue. This parameter is used to calculate the time slice of synchronous
-queue.
-
-time_slice is computed using the below equation:-
-time_slice = slice_sync + (slice_sync/5 * (4 - prio)). To increase the
-time_slice of synchronous queue, increase the value of slice_sync. Default
-value is 100ms.
-
-quantum
--------
-This specifies the number of request dispatched to the device queue. In a
-queue's time slice, a request will not be dispatched if the number of request
-in the device exceeds this parameter. This parameter is used for synchronous
-request.
-
-In case of storage with several disk, this setting can limit the parallel
-processing of request. Therefore, increasing the value can improve the
-performance although this can cause the latency of some I/O to increase due
-to more number of requests.
-
-CFQ Group scheduling
-====================
-
-CFQ supports blkio cgroup and has "blkio." prefixed files in each
-blkio cgroup directory. It is weight-based and there are four knobs
-for configuration - weight[_device] and leaf_weight[_device].
-Internal cgroup nodes (the ones with children) can also have tasks in
-them, so the former two configure how much proportion the cgroup as a
-whole is entitled to at its parent's level while the latter two
-configure how much proportion the tasks in the cgroup have compared to
-its direct children.
-
-Another way to think about it is assuming that each internal node has
-an implicit leaf child node which hosts all the tasks whose weight is
-configured by leaf_weight[_device]. Let's assume a blkio hierarchy
-composed of five cgroups - root, A, B, AA and AB - with the following
-weights where the names represent the hierarchy.
-
- weight leaf_weight
- root : 125 125
- A : 500 750
- B : 250 500
- AA : 500 500
- AB : 1000 500
-
-root never has a parent making its weight is meaningless. For backward
-compatibility, weight is always kept in sync with leaf_weight. B, AA
-and AB have no child and thus its tasks have no children cgroup to
-compete with. They always get 100% of what the cgroup won at the
-parent level. Considering only the weights which matter, the hierarchy
-looks like the following.
-
- root
- / | \
- A B leaf
- 500 250 125
- / | \
- AA AB leaf
- 500 1000 750
-
-If all cgroups have active IOs and competing with each other, disk
-time will be distributed like the following.
-
-Distribution below root. The total active weight at this level is
-A:500 + B:250 + C:125 = 875.
-
- root-leaf : 125 / 875 =~ 14%
- A : 500 / 875 =~ 57%
- B(-leaf) : 250 / 875 =~ 28%
-
-A has children and further distributes its 57% among the children and
-the implicit leaf node. The total active weight at this level is
-AA:500 + AB:1000 + A-leaf:750 = 2250.
-
- A-leaf : ( 750 / 2250) * A =~ 19%
- AA(-leaf) : ( 500 / 2250) * A =~ 12%
- AB(-leaf) : (1000 / 2250) * A =~ 25%
-
-CFQ IOPS Mode for group scheduling
-===================================
-Basic CFQ design is to provide priority based time slices. Higher priority
-process gets bigger time slice and lower priority process gets smaller time
-slice. Measuring time becomes harder if storage is fast and supports NCQ and
-it would be better to dispatch multiple requests from multiple cfq queues in
-request queue at a time. In such scenario, it is not possible to measure time
-consumed by single queue accurately.
-
-What is possible though is to measure number of requests dispatched from a
-single queue and also allow dispatch from multiple cfq queue at the same time.
-This effectively becomes the fairness in terms of IOPS (IO operations per
-second).
-
-If one sets slice_idle=0 and if storage supports NCQ, CFQ internally switches
-to IOPS mode and starts providing fairness in terms of number of requests
-dispatched. Note that this mode switching takes effect only for group
-scheduling. For non-cgroup users nothing should change.
-
-CFQ IO scheduler Idling Theory
-===============================
-Idling on a queue is primarily about waiting for the next request to come
-on same queue after completion of a request. In this process CFQ will not
-dispatch requests from other cfq queues even if requests are pending there.
-
-The rationale behind idling is that it can cut down on number of seeks
-on rotational media. For example, if a process is doing dependent
-sequential reads (next read will come on only after completion of previous
-one), then not dispatching request from other queue should help as we
-did not move the disk head and kept on dispatching sequential IO from
-one queue.
-
-CFQ has following service trees and various queues are put on these trees.
-
- sync-idle sync-noidle async
-
-All cfq queues doing synchronous sequential IO go on to sync-idle tree.
-On this tree we idle on each queue individually.
-
-All synchronous non-sequential queues go on sync-noidle tree. Also any
-synchronous write request which is not marked with REQ_IDLE goes on this
-service tree. On this tree we do not idle on individual queues instead idle
-on the whole group of queues or the tree. So if there are 4 queues waiting
-for IO to dispatch we will idle only once last queue has dispatched the IO
-and there is no more IO on this service tree.
-
-All async writes go on async service tree. There is no idling on async
-queues.
-
-CFQ has some optimizations for SSDs and if it detects a non-rotational
-media which can support higher queue depth (multiple requests at in
-flight at a time), then it cuts down on idling of individual queues and
-all the queues move to sync-noidle tree and only tree idle remains. This
-tree idling provides isolation with buffered write queues on async tree.
-
-FAQ
-===
-Q1. Why to idle at all on queues not marked with REQ_IDLE.
-
-A1. We only do tree idle (all queues on sync-noidle tree) on queues not marked
- with REQ_IDLE. This helps in providing isolation with all the sync-idle
- queues. Otherwise in presence of many sequential readers, other
- synchronous IO might not get fair share of disk.
-
- For example, if there are 10 sequential readers doing IO and they get
- 100ms each. If a !REQ_IDLE request comes in, it will be scheduled
- roughly after 1 second. If after completion of !REQ_IDLE request we
- do not idle, and after a couple of milli seconds a another !REQ_IDLE
- request comes in, again it will be scheduled after 1second. Repeat it
- and notice how a workload can lose its disk share and suffer due to
- multiple sequential readers.
-
- fsync can generate dependent IO where bunch of data is written in the
- context of fsync, and later some journaling data is written. Journaling
- data comes in only after fsync has finished its IO (atleast for ext4
- that seemed to be the case). Now if one decides not to idle on fsync
- thread due to !REQ_IDLE, then next journaling write will not get
- scheduled for another second. A process doing small fsync, will suffer
- badly in presence of multiple sequential readers.
-
- Hence doing tree idling on threads using !REQ_IDLE flag on requests
- provides isolation from multiple sequential readers and at the same
- time we do not idle on individual threads.
-
-Q2. When to specify REQ_IDLE
-A2. I would think whenever one is doing synchronous write and expecting
- more writes to be dispatched from same context soon, should be able
- to specify REQ_IDLE on writes and that probably should work well for
- most of the cases.

+=====================
+BPF Type Format (BTF)
+=====================
+
+1. Introduction
+***************
+
+BTF (BPF Type Format) is the metadata format which encodes the debug info
+related to BPF program/map. The name BTF was used initially to describe data
+types. The BTF was later extended to include function info for defined
+subroutines, and line info for source/line information.
+
+The debug info is used for map pretty print, function signature, etc. The
+function signature enables better bpf program/function kernel symbol. The line
+info helps generate source annotated translated byte code, jited code and
+verifier log.
+
+The BTF specification contains two parts,
+ * BTF kernel API
+ * BTF ELF file format
+
+The kernel API is the contract between user space and kernel. The kernel
+verifies the BTF info before using it. The ELF file format is a user space
+contract between ELF file and libbpf loader.
+
+The type and string sections are part of the BTF kernel API, describing the
+debug info (mostly types related) referenced by the bpf program. These two
+sections are discussed in details in :ref:`BTF_Type_String`.
+
+.. _BTF_Type_String:
+
+2. BTF Type and String Encoding
+*******************************
+
+The file ``include/uapi/linux/btf.h`` provides high-level definition of how
+types/strings are encoded.
+
+The beginning of data blob must be::
+
+ struct btf_header {
+ __u16 magic;
+ __u8 version;
+ __u8 flags;
+ __u32 hdr_len;
+
+ /* All offsets are in bytes relative to the end of this header */
+ __u32 type_off; /* offset of type section */
+ __u32 type_len; /* length of type section */
+ __u32 str_off; /* offset of string section */
+ __u32 str_len; /* length of string section */
+ };
+
+The magic is ``0xeB9F``, which has different encoding for big and little
+endian systems, and can be used to test whether BTF is generated for big- or
+little-endian target. The ``btf_header`` is designed to be extensible with
+``hdr_len`` equal to ``sizeof(struct btf_header)`` when a data blob is
+generated.
+
+2.1 String Encoding
+===================
+
+The first string in the string section must be a null string. The rest of
+string table is a concatenation of other null-terminated strings.
+
+2.2 Type Encoding
+=================
+
+The type id ``0`` is reserved for ``void`` type. The type section is parsed
+sequentially and type id is assigned to each recognized type starting from id
+``1``. Currently, the following types are supported::
+
+ #define BTF_KIND_INT 1 /* Integer */
+ #define BTF_KIND_PTR 2 /* Pointer */
+ #define BTF_KIND_ARRAY 3 /* Array */
+ #define BTF_KIND_STRUCT 4 /* Struct */
+ #define BTF_KIND_UNION 5 /* Union */
+ #define BTF_KIND_ENUM 6 /* Enumeration */
+ #define BTF_KIND_FWD 7 /* Forward */
+ #define BTF_KIND_TYPEDEF 8 /* Typedef */
+ #define BTF_KIND_VOLATILE 9 /* Volatile */
+ #define BTF_KIND_CONST 10 /* Const */
+ #define BTF_KIND_RESTRICT 11 /* Restrict */
+ #define BTF_KIND_FUNC 12 /* Function */
+ #define BTF_KIND_FUNC_PROTO 13 /* Function Proto */
+
+Note that the type section encodes debug info, not just pure types.
+``BTF_KIND_FUNC`` is not a type, and it represents a defined subprogram.
+
+Each type contains the following common data::
+
+ struct btf_type {
+ __u32 name_off;
+ /* "info" bits arrangement
+ * bits 0-15: vlen (e.g. # of struct's members)
+ * bits 16-23: unused
+ * bits 24-27: kind (e.g. int, ptr, array...etc)
+ * bits 28-30: unused
+ * bit 31: kind_flag, currently used by
+ * struct, union and fwd
+ */
+ __u32 info;
+ /* "size" is used by INT, ENUM, STRUCT and UNION.
+ * "size" tells the size of the type it is describing.
+ *
+ * "type" is used by PTR, TYPEDEF, VOLATILE, CONST, RESTRICT,
+ * FUNC and FUNC_PROTO.
+ * "type" is a type_id referring to another type.
+ */
+ union {
+ __u32 size;
+ __u32 type;
+ };
+ };
+
+For certain kinds, the common data are followed by kind-specific data. The
+``name_off`` in ``struct btf_type`` specifies the offset in the string table.
+The following sections detail encoding of each kind.
+
+2.2.1 BTF_KIND_INT
+~~~~~~~~~~~~~~~~~~
+
+``struct btf_type`` encoding requirement:
+ * ``name_off``: any valid offset
+ * ``info.kind_flag``: 0
+ * ``info.kind``: BTF_KIND_INT
+ * ``info.vlen``: 0
+ * ``size``: the size of the int type in bytes.
+
+``btf_type`` is followed by a ``u32`` with the following bits arrangement::
+
+ #define BTF_INT_ENCODING(VAL) (((VAL) & 0x0f000000) >> 24)
+ #define BTF_INT_OFFSET(VAL) (((VAL & 0x00ff0000)) >> 16)
+ #define BTF_INT_BITS(VAL) ((VAL) & 0x000000ff)
+
+The ``BTF_INT_ENCODING`` has the following attributes::
+
+ #define BTF_INT_SIGNED (1 << 0)
+ #define BTF_INT_CHAR (1 << 1)
+ #define BTF_INT_BOOL (1 << 2)
+
+The ``BTF_INT_ENCODING()`` provides extra information: signedness, char, or
+bool, for the int type. The char and bool encoding are mostly useful for
+pretty print. At most one encoding can be specified for the int type.
+
+The ``BTF_INT_BITS()`` specifies the number of actual bits held by this int
+type. For example, a 4-bit bitfield encodes ``BTF_INT_BITS()`` equals to 4.
+The ``btf_type.size * 8`` must be equal to or greater than ``BTF_INT_BITS()``
+for the type. The maximum value of ``BTF_INT_BITS()`` is 128.
+
+The ``BTF_INT_OFFSET()`` specifies the starting bit offset to calculate values
+for this int. For example, a bitfield struct member has:
+ * btf member bit offset 100 from the start of the structure,
+ * btf member pointing to an int type,
+ * the int type has ``BTF_INT_OFFSET() = 2`` and ``BTF_INT_BITS() = 4``
+
+Then in the struct memory layout, this member will occupy ``4`` bits starting
+from bits ``100 + 2 = 102``.
+
+Alternatively, the bitfield struct member can be the following to access the
+same bits as the above:
+ * btf member bit offset 102,
+ * btf member pointing to an int type,
+ * the int type has ``BTF_INT_OFFSET() = 0`` and ``BTF_INT_BITS() = 4``
+
+The original intention of ``BTF_INT_OFFSET()`` is to provide flexibility of
+bitfield encoding. Currently, both llvm and pahole generate
+``BTF_INT_OFFSET() = 0`` for all int types.
+
+2.2.2 BTF_KIND_PTR
+~~~~~~~~~~~~~~~~~~
+
+``struct btf_type`` encoding requirement:
+ * ``name_off``: 0
+ * ``info.kind_flag``: 0
+ * ``info.kind``: BTF_KIND_PTR
+ * ``info.vlen``: 0
+ * ``type``: the pointee type of the pointer
+
+No additional type data follow ``btf_type``.
+
+2.2.3 BTF_KIND_ARRAY
+~~~~~~~~~~~~~~~~~~~~
+
+``struct btf_type`` encoding requirement:
+ * ``name_off``: 0
+ * ``info.kind_flag``: 0
+ * ``info.kind``: BTF_KIND_ARRAY
+ * ``info.vlen``: 0
+ * ``size/type``: 0, not used
+
+``btf_type`` is followed by one ``struct btf_array``::
+
+ struct btf_array {
+ __u32 type;
+ __u32 index_type;
+ __u32 nelems;
+ };
+
+The ``struct btf_array`` encoding:
+ * ``type``: the element type
+ * ``index_type``: the index type
+ * ``nelems``: the number of elements for this array (``0`` is also allowed).
+
+The ``index_type`` can be any regular int type (``u8``, ``u16``, ``u32``,
+``u64``, ``unsigned __int128``). The original design of including
+``index_type`` follows DWARF, which has an ``index_type`` for its array type.
+Currently in BTF, beyond type verification, the ``index_type`` is not used.
+
+The ``struct btf_array`` allows chaining through element type to represent
+multidimensional arrays. For example, for ``int a[5][6]``, the following type
+information illustrates the chaining:
+
+ * [1]: int
+ * [2]: array, ``btf_array.type = [1]``, ``btf_array.nelems = 6``
+ * [3]: array, ``btf_array.type = [2]``, ``btf_array.nelems = 5``
+
+Currently, both pahole and llvm collapse multidimensional array into
+one-dimensional array, e.g., for ``a[5][6]``, the ``btf_array.nelems`` is
+equal to ``30``. This is because the original use case is map pretty print
+where the whole array is dumped out so one-dimensional array is enough. As
+more BTF usage is explored, pahole and llvm can be changed to generate proper
+chained representation for multidimensional arrays.
+
+2.2.4 BTF_KIND_STRUCT
+~~~~~~~~~~~~~~~~~~~~~
+2.2.5 BTF_KIND_UNION
+~~~~~~~~~~~~~~~~~~~~
+
+``struct btf_type`` encoding requirement:
+ * ``name_off``: 0 or offset to a valid C identifier
+ * ``info.kind_flag``: 0 or 1
+ * ``info.kind``: BTF_KIND_STRUCT or BTF_KIND_UNION
+ * ``info.vlen``: the number of struct/union members
+ * ``info.size``: the size of the struct/union in bytes
+
+``btf_type`` is followed by ``info.vlen`` number of ``struct btf_member``.::
+
+ struct btf_member {
+ __u32 name_off;
+ __u32 type;
+ __u32 offset;
+ };
+
+``struct btf_member`` encoding:
+ * ``name_off``: offset to a valid C identifier
+ * ``type``: the member type
+ * ``offset``: <see below>
+
+If the type info ``kind_flag`` is not set, the offset contains only bit offset
+of the member. Note that the base type of the bitfield can only be int or enum
+type. If the bitfield size is 32, the base type can be either int or enum
+type. If the bitfield size is not 32, the base type must be int, and int type
+``BTF_INT_BITS()`` encodes the bitfield size.
+
+If the ``kind_flag`` is set, the ``btf_member.offset`` contains both member
+bitfield size and bit offset. The bitfield size and bit offset are calculated
+as below.::
+
+ #define BTF_MEMBER_BITFIELD_SIZE(val) ((val) >> 24)
+ #define BTF_MEMBER_BIT_OFFSET(val) ((val) & 0xffffff)
+
+In this case, if the base type is an int type, it must be a regular int type:
+
+ * ``BTF_INT_OFFSET()`` must be 0.
+ * ``BTF_INT_BITS()`` must be equal to ``{1,2,4,8,16} * 8``.
+
+The following kernel patch introduced ``kind_flag`` and explained why both
+modes exist:
+
+ https://github.com/torvalds/linux/commit/9d5f9f701b1891466fb3dbb1806ad97716f95cc3#diff-fa650a64fdd3968396883d2fe8215ff3
+
+2.2.6 BTF_KIND_ENUM
+~~~~~~~~~~~~~~~~~~~
+
+``struct btf_type`` encoding requirement:
+ * ``name_off``: 0 or offset to a valid C identifier
+ * ``info.kind_flag``: 0
+ * ``info.kind``: BTF_KIND_ENUM
+ * ``info.vlen``: number of enum values
+ * ``size``: 4
+
+``btf_type`` is followed by ``info.vlen`` number of ``struct btf_enum``.::
+
+ struct btf_enum {
+ __u32 name_off;
+ __s32 val;
+ };
+
+The ``btf_enum`` encoding:

+
+No additional type data follow ``btf_type``.
+
+A BTF_KIND_FUNC defines not a type, but a subprogram (function) whose
+signature is defined by ``type``. The subprogram is thus an instance of that
+type. The BTF_KIND_FUNC may in turn be referenced by a func_info in the
+:ref:`BTF_Ext_Section` (ELF) or in the arguments to :ref:`BPF_Prog_Load`
+(ABI).
+

+ * ``info.kind``: BTF_KIND_FUNC_PROTO
+ * ``info.vlen``: # of parameters
+ * ``type``: the return type
+
+``btf_type`` is followed by ``info.vlen`` number of ``struct btf_param``.::
+
+ struct btf_param {
+ __u32 name_off;
+ __u32 type;
+ };
+
+If a BTF_KIND_FUNC_PROTO type is referred by a BTF_KIND_FUNC type, then
+``btf_param.name_off`` must point to a valid C identifier except for the
+possible last argument representing the variable argument. The btf_param.type
+refers to parameter type.
+
+If the function has variable arguments, the last parameter is encoded with
+``name_off = 0`` and ``type = 0``.
+
+3. BTF Kernel API
+*****************
+
+The following bpf syscall command involves BTF:
+ * BPF_BTF_LOAD: load a blob of BTF data into kernel
+ * BPF_MAP_CREATE: map creation with btf key and value type info.
+ * BPF_PROG_LOAD: prog load with btf function and line info.
+ * BPF_BTF_GET_FD_BY_ID: get a btf fd
+ * BPF_OBJ_GET_INFO_BY_FD: btf, func_info, line_info
+ and other btf related info are returned.
+
+The workflow typically looks like:
+::
+
+ Application:
+ BPF_BTF_LOAD
+ |
+ v
+ BPF_MAP_CREATE and BPF_PROG_LOAD
+ |
+ V
+ ......
+
+ Introspection tool:

+ BPF_{PROG,MAP}_GET_NEXT_ID (get prog/map id's)
+ |
+ V
+ BPF_{PROG,MAP}_GET_FD_BY_ID (get a prog/map fd)
+ |
+ V
+ BPF_OBJ_GET_INFO_BY_FD (get bpf_prog_info/bpf_map_info with btf_id)
+ | |
+ V |
+ BPF_BTF_GET_FD_BY_ID (get btf_fd) |
+ | |
+ V |
+ BPF_OBJ_GET_INFO_BY_FD (get btf) |
+ | |
+ V V
+ pretty print types, dump func signatures and line info, etc.
+
+
+3.1 BPF_BTF_LOAD
+================
+
+Load a blob of BTF data into kernel. A blob of data, described in
+:ref:`BTF_Type_String`, can be directly loaded into the kernel. A ``btf_fd``
+is returned to a userspace.
+
+3.2 BPF_MAP_CREATE
+==================
+
+A map can be created with ``btf_fd`` and specified key/value type id.::
+
+ __u32 btf_fd; /* fd pointing to a BTF type data */
+ __u32 btf_key_type_id; /* BTF type_id of the key */
+ __u32 btf_value_type_id; /* BTF type_id of the value */
+
+In libbpf, the map can be defined with extra annotation like below:
+::
+
+ struct bpf_map_def SEC("maps") btf_map = {
+ .type = BPF_MAP_TYPE_ARRAY,
+ .key_size = sizeof(int),
+ .value_size = sizeof(struct ipv_counts),
+ .max_entries = 4,
+ };
+ BPF_ANNOTATE_KV_PAIR(btf_map, int, struct ipv_counts);
+
+Here, the parameters for macro BPF_ANNOTATE_KV_PAIR are map name, key and
+value types for the map. During ELF parsing, libbpf is able to extract
+key/value type_id's and assign them to BPF_MAP_CREATE attributes
+automatically.
+
+.. _BPF_Prog_Load:
+
+3.3 BPF_PROG_LOAD
+=================
+
+During prog_load, func_info and line_info can be passed to kernel with proper
+values for the following attributes:
+::
+
+ __u32 insn_cnt;
+ __aligned_u64 insns;
+ ......
+ __u32 prog_btf_fd; /* fd pointing to BTF type data */
+ __u32 func_info_rec_size; /* userspace bpf_func_info size */
+ __aligned_u64 func_info; /* func info */
+ __u32 func_info_cnt; /* number of bpf_func_info records */
+ __u32 line_info_rec_size; /* userspace bpf_line_info size */
+ __aligned_u64 line_info; /* line info */
+ __u32 line_info_cnt; /* number of bpf_line_info records */
+
+The func_info and line_info are an array of below, respectively.::
+
+ struct bpf_func_info {
+ __u32 insn_off; /* [0, insn_cnt - 1] */
+ __u32 type_id; /* pointing to a BTF_KIND_FUNC type */
+ };
+ struct bpf_line_info {
+ __u32 insn_off; /* [0, insn_cnt - 1] */
+ __u32 file_name_off; /* offset to string table for the filename */
+ __u32 line_off; /* offset to string table for the source line */
+ __u32 line_col; /* line number and column number */
+ };
+
+func_info_rec_size is the size of each func_info record, and
+line_info_rec_size is the size of each line_info record. Passing the record
+size to kernel make it possible to extend the record itself in the future.
+
+Below are requirements for func_info:
+ * func_info[0].insn_off must be 0.
+ * the func_info insn_off is in strictly increasing order and matches
+ bpf func boundaries.
+
+Below are requirements for line_info:
+ * the first insn in each func must have a line_info record pointing to it.
+ * the line_info insn_off is in strictly increasing order.
+
+For line_info, the line number and column number are defined as below:
+::
+
+ #define BPF_LINE_INFO_LINE_NUM(line_col) ((line_col) >> 10)
+ #define BPF_LINE_INFO_LINE_COL(line_col) ((line_col) & 0x3ff)
+
+3.4 BPF_{PROG,MAP}_GET_NEXT_ID
+
+In kernel, every loaded program, map or btf has a unique id. The id won't
+change during the lifetime of a program, map, or btf.
+
+The bpf syscall command BPF_{PROG,MAP}_GET_NEXT_ID returns all id's, one for
+each command, to user space, for bpf program or maps, respectively, so an
+inspection tool can inspect all programs and maps.
+
+3.5 BPF_{PROG,MAP}_GET_FD_BY_ID
+
+An introspection tool cannot use id to get details about program or maps.
+A file descriptor needs to be obtained first for reference-counting purpose.
+
+3.6 BPF_OBJ_GET_INFO_BY_FD
+==========================
+
+Once a program/map fd is acquired, an introspection tool can get the detailed
+information from kernel about this fd, some of which are BTF-related. For
+example, ``bpf_map_info`` returns ``btf_id`` and key/value type ids.
+``bpf_prog_info`` returns ``btf_id``, func_info, and line info for translated
+bpf byte codes, and jited_line_info.
+
+3.7 BPF_BTF_GET_FD_BY_ID
+========================
+
+With ``btf_id`` obtained in ``bpf_map_info`` and ``bpf_prog_info``, bpf
+syscall command BPF_BTF_GET_FD_BY_ID can retrieve a btf fd. Then, with
+command BPF_OBJ_GET_INFO_BY_FD, the btf blob, originally loaded into the
+kernel with BPF_BTF_LOAD, can be retrieved.
+
+With the btf blob, ``bpf_map_info``, and ``bpf_prog_info``, an introspection
+tool has full btf knowledge and is able to pretty print map key/values, dump
+func signatures and line info, along with byte/jit codes.
+
+4. ELF File Format Interface
+****************************
+
+4.1 .BTF section
+================
+
+The .BTF section contains type and string data. The format of this section is
+same as the one describe in :ref:`BTF_Type_String`.
+
+.. _BTF_Ext_Section:
+
+4.2 .BTF.ext section
+====================
+
+The .BTF.ext section encodes func_info and line_info which needs loader
+manipulation before loading into the kernel.
+
+The specification for .BTF.ext section is defined at ``tools/lib/bpf/btf.h``
+and ``tools/lib/bpf/btf.c``.
+
+The current header of .BTF.ext section::
+
+ struct btf_ext_header {
+ __u16 magic;
+ __u8 version;
+ __u8 flags;
+ __u32 hdr_len;
+
+ /* All offsets are in bytes relative to the end of this header */
+ __u32 func_info_off;
+ __u32 func_info_len;
+ __u32 line_info_off;
+ __u32 line_info_len;
+ };
+
+It is very similar to .BTF section. Instead of type/string section, it
+contains func_info and line_info section. See :ref:`BPF_Prog_Load` for details
+about func_info and line_info record format.
+
+The func_info is organized as below.::
+
+ func_info_rec_size
+ btf_ext_info_sec for section #1 /* func_info for section #1 */
+ btf_ext_info_sec for section #2 /* func_info for section #2 */
+ ...
+
+``func_info_rec_size`` specifies the size of ``bpf_func_info`` structure when
+.BTF.ext is generated. ``btf_ext_info_sec``, defined below, is a collection of
+func_info for each specific ELF section.::
+
+ struct btf_ext_info_sec {
+ __u32 sec_name_off; /* offset to section name */
+ __u32 num_info;
+ /* Followed by num_info * record_size number of bytes */
+ __u8 data[0];
+ };
+
+Here, num_info must be greater than 0.
+
+The line_info is organized as below.::
+
+ line_info_rec_size
+ btf_ext_info_sec for section #1 /* line_info for section #1 */
+ btf_ext_info_sec for section #2 /* line_info for section #2 */
+ ...
+
+``line_info_rec_size`` specifies the size of ``bpf_line_info`` structure when
+.BTF.ext is generated.
+
+The interpretation of ``bpf_func_info->insn_off`` and
+``bpf_line_info->insn_off`` is different between kernel API and ELF API. For
+kernel API, the ``insn_off`` is the instruction offset in the unit of ``struct
+bpf_insn``. For ELF API, the ``insn_off`` is the byte offset from the
+beginning of section (``btf_ext_info_sec->sec_name_off``).
+
+5. Using BTF
+************
+
+5.1 bpftool map pretty print
+============================
+
+With BTF, the map key/value can be printed based on fields rather than simply
+raw bytes. This is especially valuable for large structure or if your data
+structure has bitfields. For example, for the following map,::
+
+ enum A { A1, A2, A3, A4, A5 };
+ typedef enum A ___A;
+ struct tmp_t {
+ char a1:4;
+ int a2:4;
+ int :4;
+ __u32 a3:4;
+ int b;
+ ___A b1:4;
+ enum A b2:4;
+ };
+ struct bpf_map_def SEC("maps") tmpmap = {
+ .type = BPF_MAP_TYPE_ARRAY,
+ .key_size = sizeof(__u32),
+ .value_size = sizeof(struct tmp_t),
+ .max_entries = 1,
+ };
+ BPF_ANNOTATE_KV_PAIR(tmpmap, int, struct tmp_t);
+
+bpftool is able to pretty print like below:
+::
+
+ [{
+ "key": 0,
+ "value": {
+ "a1": 0x2,
+ "a2": 0x4,
+ "a3": 0x6,
+ "b": 7,
+ "b1": 0x8,
+ "b2": 0xa
+ }
+ }
+ ]
+
+5.2 bpftool prog dump
+=====================
+
+The following is an example showing how func_info and line_info can help prog
+dump with better kernel symbol names, function prototypes and line
+information.::
+
+ $ bpftool prog dump jited pinned /sys/fs/bpf/test_btf_haskv
+ [...]
+ int test_long_fname_2(struct dummy_tracepoint_args * arg):
+ bpf_prog_44a040bf25481309_test_long_fname_2:
+ ; static int test_long_fname_2(struct dummy_tracepoint_args *arg)
+ 0: push %rbp
+ 1: mov %rsp,%rbp
+ 4: sub $0x30,%rsp
+ b: sub $0x28,%rbp
+ f: mov %rbx,0x0(%rbp)
+ 13: mov %r13,0x8(%rbp)
+ 17: mov %r14,0x10(%rbp)
+ 1b: mov %r15,0x18(%rbp)
+ 1f: xor %eax,%eax
+ 21: mov %rax,0x20(%rbp)
+ 25: xor %esi,%esi
+ ; int key = 0;
+ 27: mov %esi,-0x4(%rbp)
+ ; if (!arg->sock)
+ 2a: mov 0x8(%rdi),%rdi
+ ; if (!arg->sock)
+ 2e: cmp $0x0,%rdi
+ 32: je 0x0000000000000070
+ 34: mov %rbp,%rsi
+ ; counts = bpf_map_lookup_elem(&btf_map, &key);
+ [...]
+
+5.3 Verifier Log
+================
+
+The following is an example of how line_info can help debugging verification
+failure.::
+
+ /* The code at tools/testing/selftests/bpf/test_xdp_noinline.c
+ * is modified as below.
+ */
+ data = (void *)(long)xdp->data;
+ data_end = (void *)(long)xdp->data_end;
+ /*
+ if (data + 4 > data_end)
+ return XDP_DROP;
+ */
+ *(u32 *)data = dst->dst;
+
+ $ bpftool prog load ./test_xdp_noinline.o /sys/fs/bpf/test_xdp_noinline type xdp
+ ; data = (void *)(long)xdp->data;
+ 224: (79) r2 = *(u64 *)(r10 -112)
+ 225: (61) r2 = *(u32 *)(r2 +0)
+ ; *(u32 *)data = dst->dst;
+ 226: (63) *(u32 *)(r2 +0) = r1
+ invalid access to packet, off=0 size=4, R2(id=0,off=0,r=0)
+ R2 offset is outside of the packet
+
+6. BTF Generation
+*****************
+
+You need latest pahole
+
+ https://git.kernel.org/pub/scm/devel/pahole/pahole.git/
+
+or llvm (8.0 or later). The pahole acts as a dwarf2btf converter. It doesn't
+support .BTF.ext and btf BTF_KIND_FUNC type yet. For example,::
+
+ -bash-4.4$ cat t.c
+ struct t {
+ int a:2;
+ int b:3;
+ int c:2;
+ } g;
+ -bash-4.4$ gcc -c -O2 -g t.c
+ -bash-4.4$ pahole -JV t.o
+ File t.o:
+ [1] STRUCT t kind_flag=1 size=4 vlen=3
+ a type_id=2 bitfield_size=2 bits_offset=0
+ b type_id=2 bitfield_size=3 bits_offset=2
+ c type_id=2 bitfield_size=2 bits_offset=5
+ [2] INT int size=4 bit_offset=0 nr_bits=32 encoding=SIGNED
+
+The llvm is able to generate .BTF and .BTF.ext directly with -g for bpf target
+only. The assembly code (-S) is able to show the BTF encoding in assembly
+format.::
+
+ -bash-4.4$ cat t2.c
+ typedef int __int32;
+ struct t2 {
+ int a2;
+ int (*f2)(char q1, __int32 q2, ...);

-===================================
-Using flexible arrays in the kernel
-===================================
-
-Large contiguous memory allocations can be unreliable in the Linux kernel.
-Kernel programmers will sometimes respond to this problem by allocating
-pages with :c:func:`vmalloc()`. This solution not ideal, though. On 32-bit
-systems, memory from vmalloc() must be mapped into a relatively small address
-space; it's easy to run out. On SMP systems, the page table changes required
-by vmalloc() allocations can require expensive cross-processor interrupts on
-all CPUs. And, on all systems, use of space in the vmalloc() range increases
-pressure on the translation lookaside buffer (TLB), reducing the performance
-of the system.
-
-In many cases, the need for memory from vmalloc() can be eliminated by piecing
-together an array from smaller parts; the flexible array library exists to make
-this task easier.
-
-A flexible array holds an arbitrary (within limits) number of fixed-sized
-objects, accessed via an integer index. Sparse arrays are handled
-reasonably well. Only single-page allocations are made, so memory
-allocation failures should be relatively rare. The down sides are that the
-arrays cannot be indexed directly, individual object size cannot exceed the
-system page size, and putting data into a flexible array requires a copy
-operation. It's also worth noting that flexible arrays do no internal
-locking at all; if concurrent access to an array is possible, then the
-caller must arrange for appropriate mutual exclusion.
-
-The creation of a flexible array is done with :c:func:`flex_array_alloc()`::
-
- #include <linux/flex_array.h>
-
- struct flex_array *flex_array_alloc(int element_size,
- unsigned int total,
- gfp_t flags);
-
-The individual object size is provided by ``element_size``, while total is the
-maximum number of objects which can be stored in the array. The flags
-argument is passed directly to the internal memory allocation calls. With
-the current code, using flags to ask for high memory is likely to lead to
-notably unpleasant side effects.
-
-It is also possible to define flexible arrays at compile time with::
-
- DEFINE_FLEX_ARRAY(name, element_size, total);
-
-This macro will result in a definition of an array with the given name; the
-element size and total will be checked for validity at compile time.
-
-Storing data into a flexible array is accomplished with a call to
-:c:func:`flex_array_put()`::
-
- int flex_array_put(struct flex_array *array, unsigned int element_nr,
- void *src, gfp_t flags);
-
-This call will copy the data from src into the array, in the position
-indicated by ``element_nr`` (which must be less than the maximum specified when
-the array was created). If any memory allocations must be performed, flags
-will be used. The return value is zero on success, a negative error code
-otherwise.
-
-There might possibly be a need to store data into a flexible array while
-running in some sort of atomic context; in this situation, sleeping in the
-memory allocator would be a bad thing. That can be avoided by using
-``GFP_ATOMIC`` for the flags value, but, often, there is a better way. The
-trick is to ensure that any needed memory allocations are done before
-entering atomic context, using :c:func:`flex_array_prealloc()`::
-
- int flex_array_prealloc(struct flex_array *array, unsigned int start,
- unsigned int nr_elements, gfp_t flags);
-
-This function will ensure that memory for the elements indexed in the range
-defined by ``start`` and ``nr_elements`` has been allocated. Thereafter, a
-``flex_array_put()`` call on an element in that range is guaranteed not to
-block.
-
-Getting data back out of the array is done with :c:func:`flex_array_get()`::
-
- void *flex_array_get(struct flex_array *fa, unsigned int element_nr);
-
-The return value is a pointer to the data element, or NULL if that
-particular element has never been allocated.
-
-Note that it is possible to get back a valid pointer for an element which
-has never been stored in the array. Memory for array elements is allocated
-one page at a time; a single allocation could provide memory for several
-adjacent elements. Flexible array elements are normally initialized to the
-value ``FLEX_ARRAY_FREE`` (defined as 0x6c in <linux/poison.h>), so errors
-involving that number probably result from use of unstored array entries.
-Note that, if array elements are allocated with ``__GFP_ZERO``, they will be
-initialized to zero and this poisoning will not happen.
-
-Individual elements in the array can be cleared with
-:c:func:`flex_array_clear()`::
-
- int flex_array_clear(struct flex_array *array, unsigned int element_nr);
-
-This function will set the given element to ``FLEX_ARRAY_FREE`` and return
-zero. If storage for the indicated element is not allocated for the array,
-``flex_array_clear()`` will return ``-EINVAL`` instead. Note that clearing an
-element does not release the storage associated with it; to reduce the
-allocated size of an array, call :c:func:`flex_array_shrink()`::
-
- int flex_array_shrink(struct flex_array *array);
-
-The return value will be the number of pages of memory actually freed.
-This function works by scanning the array for pages containing nothing but
-``FLEX_ARRAY_FREE`` bytes, so (1) it can be expensive, and (2) it will not work
-if the array's pages are allocated with ``__GFP_ZERO``.
-
-It is possible to remove all elements of an array with a call to
-:c:func:`flex_array_free_parts()`::
-
- void flex_array_free_parts(struct flex_array *array);
-
-This call frees all elements, but leaves the array itself in place.
-Freeing the entire array is done with :c:func:`flex_array_free()`::
-
- void flex_array_free(struct flex_array *array);
-
-As of this writing, there are no users of flexible arrays in the mainline
-kernel. The functions described here are also not exported to modules;
-that will probably be fixed when somebody comes up with a need for it.

-General Information:
-
-Various CPUs today support multiple idle levels that are differentiated
-by varying exit latencies and power consumption during idle.
-cpuidle is a generic in-kernel infrastructure that separates
-idle policy (governor) from idle mechanism (driver) and provides a
-standardized infrastructure to support independent development of
-governors and drivers.
-
-cpuidle resides under drivers/cpuidle.
-
-Boot options:
-"cpuidle_sysfs_switch"
-enables current_governor interface in /sys/devices/system/cpu/cpuidle/,
-which can be used to switch governors at run time. This boot option
-is meant for developer testing only. In normal usage, kernel picks the
-best governor based on governor ratings.

Programming Interface
=====================

-(crypto_aead_giv\* and aead_givcrypt\* function calls in

-seqniv(rfc4106(gcm(aes))) implies that the kernel crypto API generates
-the IV. Different IV generators are available.

Overview

-KernelAddressSANitizer (KASAN) is a dynamic memory error detector. It provides
-a fast and comprehensive solution for finding use-after-free and out-of-bounds
-bugs.
+KernelAddressSANitizer (KASAN) is a dynamic memory error detector designed to
+find out-of-bound and use-after-free bugs. KASAN has two modes: generic KASAN
+(similar to userspace ASan) and software tag-based KASAN (similar to userspace
+HWASan).
-KASAN uses compile-time instrumentation for checking every memory access,
-therefore you will need a GCC version 4.9.2 or later. GCC 5.0 or later is
-required for detection of out-of-bounds accesses to stack or global variables.
+KASAN uses compile-time instrumentation to insert validity checks before every
+memory access, and therefore requires a compiler version that supports that.
-Currently KASAN is supported only for the x86_64 and arm64 architectures.
+Generic KASAN is supported in both GCC and Clang. With GCC it requires version
+4.9.2 or later for basic support and version 5.0 or later for detection of
+out-of-bounds accesses for stack and global variables and for inline
+instrumentation mode (see the Usage section). With Clang it requires version
+7.0.0 or later and it doesn't support detection of out-of-bounds accesses for
+global variables yet.
+
+Tag-based KASAN is only supported in Clang and requires version 7.0.0 or later.
+
+Currently generic KASAN is supported for the x86_64, arm64, xtensa and s390

This option significantly enlarges kernel but it gives x1.1-x2 performance
boost over outline instrumented kernel.

+Software tag-based KASAN
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+Tag-based KASAN uses the Top Byte Ignore (TBI) feature of modern arm64 CPUs to
+store a pointer tag in the top byte of kernel pointers. Like generic KASAN it
+uses shadow memory to store memory tags associated with each 16-byte memory
+cell (therefore it dedicates 1/16th of the kernel memory for shadow memory).
+
+On each memory allocation tag-based KASAN generates a random tag, tags the
+allocated memory with this tag, and embeds this tag into the returned pointer.
+Software tag-based KASAN uses compile-time instrumentation to insert checks
+before each memory access. These checks make sure that tag of the memory that
+is being accessed is equal to tag of the pointer that is used to access this
+memory. In case of a tag mismatch tag-based KASAN prints a bug report.
+
+Software tag-based KASAN also has two instrumentation modes (outline, that
+emits callbacks to check memory accesses; and inline, that performs the shadow
+memory checks inline). With outline instrumentation mode, a bug report is
+simply printed from the function that performs the access check. With inline
+instrumentation a brk instruction is emitted by the compiler, and a dedicated
+brk handler is used to print bug reports.
+
+A potential expansion of this mode is a hardware tag-based mode, which would
+use hardware memory tagging support instead of compiler instrumentation and
+manual shadow memory manipulation.

+Early creation of mapped devices
+====================================
+
+It is possible to configure a device-mapper device to act as the root device for
+your system in two ways.
+
+The first is to build an initial ramdisk which boots to a minimal userspace
+which configures the device, then pivot_root(8) in to it.
+
+The second is to create one or more device-mappers using the module parameter
+"dm-mod.create=" through the kernel boot command line argument.
+
+The format is specified as a string of data separated by commas and optionally
+semi-colons, where:
+ - a comma is used to separate fields like name, uuid, flags and table
+ (specifies one device)
+ - a semi-colon is used to separate devices.
+
+So the format will look like this:
+
+ dm-mod.create=<name>,<uuid>,<minor>,<flags>,<table>[,<table>+][;<name>,<uuid>,<minor>,<flags>,<table>[,<table>+]+]
+
+Where,
+ <name> ::= The device name.
+ <uuid> ::= xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx | ""
+ <minor> ::= The device minor number | ""
+ <flags> ::= "ro" | "rw"
+ <table> ::= <start_sector> <num_sectors> <target_type> <target_args>
+ <target_type> ::= "verity" | "linear" | ... (see list below)
+
+The dm line should be equivalent to the one used by the dmsetup tool with the
+--concise argument.
+
+Target types
+============
+
+Not all target types are available as there are serious risks in allowing
+activation of certain DM targets without first using userspace tools to check
+the validity of associated metadata.
+
+ "cache": constrained, userspace should verify cache device
+ "crypt": allowed
+ "delay": allowed
+ "era": constrained, userspace should verify metadata device
+ "flakey": constrained, meant for test
+ "linear": allowed
+ "log-writes": constrained, userspace should verify metadata device
+ "mirror": constrained, userspace should verify main/mirror device
+ "raid": constrained, userspace should verify metadata device
+ "snapshot": constrained, userspace should verify src/dst device
+ "snapshot-origin": allowed
+ "snapshot-merge": constrained, userspace should verify src/dst device
+ "striped": allowed
+ "switch": constrained, userspace should verify dev path
+ "thin": constrained, requires dm target message from userspace
+ "thin-pool": constrained, requires dm target message from userspace
+ "verity": allowed
+ "writecache": constrained, userspace should verify cache device
+ "zero": constrained, not meant for rootfs
+
+If the target is not listed above, it is constrained by default (not tested).
+
+Examples
+========
+An example of booting to a linear array made up of user-mode linux block
+devices:
+
+ dm-mod.create="lroot,,,rw, 0 4096 linear 98:16 0, 4096 4096 linear 98:32 0" root=/dev/dm-0
+
+This will boot to a rw dm-linear target of 8192 sectors split across two block
+devices identified by their major:minor numbers. After boot, udev will rename
+this target to /dev/mapper/lroot (depending on the rules). No uuid was assigned.
+
+An example of multiple device-mappers, with the dm-mod.create="..." contents is shown here
+split on multiple lines for readability:
+
+ vroot,,,ro,
+ 0 1740800 verity 254:0 254:0 1740800 sha1

-=================
-ARM CPUs bindings
-=================
-
-The device tree allows to describe the layout of CPUs in a system through
-the "cpus" node, which in turn contains a number of subnodes (ie "cpu")
-defining properties for every cpu.
-
-Bindings for CPU nodes follow the Devicetree Specification, available from:
-
-https://www.devicetree.org/specifications/
-
-with updates for 32-bit and 64-bit ARM systems provided in this document.
-
-================================
-Convention used in this document
-================================
-
-This document follows the conventions described in the Devicetree
-Specification, with the addition:
-
-- square brackets define bitfields, eg reg[7:0] value of the bitfield in
- the reg property contained in bits 7 down to 0
-
-=====================================
-cpus and cpu node bindings definition
-=====================================
-
-The ARM architecture, in accordance with the Devicetree Specification,
-requires the cpus and cpu nodes to be present and contain the properties
-described below.
-
-- cpus node
-
- Description: Container of cpu nodes
-
- The node name must be "cpus".
-
- A cpus node must define the following properties:
-
- - #address-cells
- Usage: required
- Value type: <u32>
-
- Definition depends on ARM architecture version and
- configuration:
-
- # On uniprocessor ARM architectures previous to v7
- value must be 1, to enable a simple enumeration
- scheme for processors that do not have a HW CPU
- identification register.
- # On 32-bit ARM 11 MPcore, ARM v7 or later systems
- value must be 1, that corresponds to CPUID/MPIDR
- registers sizes.
- # On ARM v8 64-bit systems value should be set to 2,
- that corresponds to the MPIDR_EL1 register size.
- If MPIDR_EL1[63:32] value is equal to 0 on all CPUs
- in the system, #address-cells can be set to 1, since
- MPIDR_EL1[63:32] bits are not used for CPUs
- identification.
- - #size-cells
- Usage: required
- Value type: <u32>
- Definition: must be set to 0

-
- All other bits in the reg cell must be set to 0.
-
- # On ARM v8 64-bit systems this property is required
- and matches the MPIDR_EL1 register affinity bits.
-
- * If cpus node's #address-cells property is set to 2
-
- The first reg cell bits [7:0] must be set to
- bits [39:32] of MPIDR_EL1.
-

-* ARM L2 Cache Controller
-
-ARM cores often have a separate L2C210/L2C220/L2C310 (also known as PL210/PL220/
-PL310 and variants) based level 2 cache controller. All these various implementations
-of the L2 cache controller have compatible programming models (Note 1).
-Some of the properties that are just prefixed "cache-*" are taken from section
-3.7.3 of the Devicetree Specification which can be found at:
-https://www.devicetree.org/specifications/
-
-The ARM L2 cache representation in the device tree should be done as follows:
-
-Required properties:
-
-- compatible : should be one of:
- "arm,pl310-cache"
- "arm,l220-cache"
- "arm,l210-cache"
- "bcm,bcm11351-a2-pl310-cache": DEPRECATED by "brcm,bcm11351-a2-pl310-cache"
- "brcm,bcm11351-a2-pl310-cache": For Broadcom bcm11351 chipset where an
- offset needs to be added to the address before passing down to the L2
- cache controller
- "marvell,aurora-system-cache": Marvell Controller designed to be
- compatible with the ARM one, with system cache mode (meaning
- maintenance operations on L1 are broadcasted to the L2 and L2
- performs the same operation).
- "marvell,aurora-outer-cache": Marvell Controller designed to be
- compatible with the ARM one with outer cache mode.
- "marvell,tauros3-cache": Marvell Tauros3 cache controller, compatible
- with arm,pl310-cache controller.
-- cache-unified : Specifies the cache is a unified cache.
-- cache-level : Should be set to 2 for a level 2 cache.
-- reg : Physical base address and size of cache controller's memory mapped
- registers.
-
-Optional properties:
-
-- arm,data-latency : Cycles of latency for Data RAM accesses. Specifies 3 cells of
- read, write and setup latencies. Minimum valid values are 1. Controllers
- without setup latency control should use a value of 0.
-- arm,tag-latency : Cycles of latency for Tag RAM accesses. Specifies 3 cells of
- read, write and setup latencies. Controllers without setup latency control
- should use 0. Controllers without separate read and write Tag RAM latency
- values should only use the first cell.
-- arm,dirty-latency : Cycles of latency for Dirty RAMs. This is a single cell.
-- arm,filter-ranges : <start length> Starting address and length of window to
- filter. Addresses in the filter window are directed to the M1 port. Other
- addresses will go to the M0 port.
-- arm,io-coherent : indicates that the system is operating in an hardware
- I/O coherent mode. Valid only when the arm,pl310-cache compatible
- string is used.
-- interrupts : 1 combined interrupt.
-- cache-size : specifies the size in bytes of the cache
-- cache-sets : specifies the number of associativity sets of the cache
-- cache-block-size : specifies the size in bytes of a cache block
-- cache-line-size : specifies the size in bytes of a line in the cache,
- if this is not specified, the line size is assumed to be equal to the
- cache block size
-- cache-id-part: cache id part number to be used if it is not present
- on hardware
-- wt-override: If present then L2 is forced to Write through mode
-- arm,double-linefill : Override double linefill enable setting. Enable if
- non-zero, disable if zero.
-- arm,double-linefill-incr : Override double linefill on INCR read. Enable
- if non-zero, disable if zero.
-- arm,double-linefill-wrap : Override double linefill on WRAP read. Enable
- if non-zero, disable if zero.
-- arm,prefetch-drop : Override prefetch drop enable setting. Enable if non-zero,
- disable if zero.
-- arm,prefetch-offset : Override prefetch offset value. Valid values are
- 0-7, 15, 23, and 31.
-- arm,shared-override : The default behavior of the L220 or PL310 cache
- controllers with respect to the shareable attribute is to transform "normal
- memory non-cacheable transactions" into "cacheable no allocate" (for reads)
- or "write through no write allocate" (for writes).
- On systems where this may cause DMA buffer corruption, this property must be
- specified to indicate that such transforms are precluded.
-- arm,parity-enable : enable parity checking on the L2 cache (L220 or PL310).
-- arm,parity-disable : disable parity checking on the L2 cache (L220 or PL310).
-- arm,outer-sync-disable : disable the outer sync operation on the L2 cache.
- Some core tiles, especially ARM PB11MPCore have a faulty L220 cache that
- will randomly hang unless outer sync operations are disabled.
-- prefetch-data : Data prefetch. Value: <0> (forcibly disable), <1>
- (forcibly enable), property absent (retain settings set by firmware)
-- prefetch-instr : Instruction prefetch. Value: <0> (forcibly disable),
- <1> (forcibly enable), property absent (retain settings set by
- firmware)
-- arm,dynamic-clock-gating : L2 dynamic clock gating. Value: <0> (forcibly
- disable), <1> (forcibly enable), property absent (OS specific behavior,
- preferably retain firmware settings)
-- arm,standby-mode: L2 standby mode enable. Value <0> (forcibly disable),
- <1> (forcibly enable), property absent (OS specific behavior,
- preferably retain firmware settings)
-- arm,early-bresp-disable : Disable the CA9 optimization Early BRESP (PL310)
-- arm,full-line-zero-disable : Disable the CA9 optimization Full line of zero
- write (PL310)
-
-Example:
-
-L2: cache-controller {
- compatible = "arm,pl310-cache";
- reg = <0xfff12000 0x1000>;
- arm,data-latency = <1 1 1>;
- arm,tag-latency = <2 2 2>;
- arm,filter-ranges = <0x80000000 0x8000000>;
- cache-unified;
- cache-level = <2>;
- interrupts = <45>;
-};
-
-Note 1: The description in this document doesn't apply to integrated L2
- cache controllers as found in e.g. Cortex-A15/A7/A57/A53. These

- in the kernel at all.

-* ARM Primecell Peripherals
-
-ARM, Ltd. Primecell peripherals have a standard id register that can be used to
-identify the peripheral type, vendor, and revision. This value can be used for
-driver matching.
-
-Required properties:
-
-- compatible : should be a specific name for the peripheral and
- "arm,primecell". The specific name will match the ARM
- engineering name for the logic block in the form: "arm,pl???"
-
-Optional properties:
-
-- arm,primecell-periphid : Value to override the h/w value with
-- clocks : From common clock binding. First clock is phandle to clock for apb
- pclk. Additional clocks are optional and specific to those peripherals.
-- clock-names : From common clock binding. Shall be "apb_pclk" for first clock.
-- dmas : From common DMA binding. If present, refers to one or more dma channels.
-- dma-names : From common DMA binding, needs to match the 'dmas' property.
- Devices with exactly one receive and transmit channel shall name
- these "rx" and "tx", respectively.
-- pinctrl-<n> : Pinctrl states as described in bindings/pinctrl/pinctrl-bindings.txt
-- pinctrl-names : Names corresponding to the numbered pinctrl states
-- interrupts : one or more interrupt specifiers
-- interrupt-names : names corresponding to the interrupts properties
-
-Example:
-
-serial@fff36000 {
- compatible = "arm,pl011", "arm,primecell";
- arm,primecell-periphid = <0x00341011>;
-
- clocks = <&pclk>;
- clock-names = "apb_pclk";
-
- dmas = <&dma-controller 4>, <&dma-controller 5>;
- dma-names = "rx", "tx";
-
- pinctrl-0 = <&uart0_default_mux>, <&uart0_default_mode>;
- pinctrl-1 = <&uart0_sleep_mode>;
- pinctrl-names = "default","sleep";
-
- interrupts = <0 11 0x4>;
-};

-QCOM device tree bindings
--------------------------
-
-Some qcom based bootloaders identify the dtb blob based on a set of
-device properties like SoC and platform and revisions of those components.
-To support this scheme, we encode this information into the board compatible
-string.
-
-Each board must specify a top-level board compatible string with the following
-format:
-
- compatible = "qcom,<SoC>[-<soc_version>][-<foundry_id>]-<board>[/<subtype>][-<board_version>]"
-
-The 'SoC' and 'board' elements are required. All other elements are optional.
-
-The 'SoC' element must be one of the following strings:
-
- apq8016
- apq8074
- apq8084
- apq8096
- msm8916
- msm8974
- msm8992
- msm8994
- msm8996
- mdm9615
- ipq8074
- sdm845
-
-The 'board' element must be one of the following strings:
-
- cdp
- liquid
- dragonboard
- mtp
- sbc
- hk01
-
-The 'soc_version' and 'board_version' elements take the form of v<Major>.<Minor>
-where the minor number may be omitted when it's zero, i.e. v1.0 is the same
-as v1. If all versions of the 'board_version' elements match, then a
-wildcard '*' should be used, e.g. 'v*'.
-
-The 'foundry_id' and 'subtype' elements are one or more digits from 0 to 9.
-
-Examples:
-
- "qcom,msm8916-v1-cdp-pm8916-v2.1"
-
-A CDP board with an msm8916 SoC, version 1 paired with a pm8916 PMIC of version
-2.1.
-
- "qcom,apq8074-v2.0-2-dragonboard/1-v0.1"
-
-A dragonboard board v0.1 of subtype 1 with an apq8074 SoC version 2, made in
-foundry 2.

+* Clock bindings for Freescale i.MX7ULP
+
+i.MX7ULP Clock functions are under joint control of the System
+Clock Generation (SCG) modules, Peripheral Clock Control (PCC)
+modules, and Core Mode Controller (CMC)1 blocks
+
+The clocking scheme provides clear separation between M4 domain
+and A7 domain. Except for a few clock sources shared between two
+domains, such as the System Oscillator clock, the Slow IRC (SIRC),
+and and the Fast IRC clock (FIRCLK), clock sources and clock
+management are separated and contained within each domain.
+
+M4 clock management consists of SCG0, PCC0, PCC1, and CMC0 modules.
+A7 clock management consists of SCG1, PCC2, PCC3, and CMC1 modules.
+
+Note: this binding doc is only for A7 clock domain.
+
+System Clock Generation (SCG) modules:
+---------------------------------------------------------------------
+The System Clock Generation (SCG) is responsible for clock generation
+and distribution across this device. Functions performed by the SCG
+include: clock reference selection, generation of clock used to derive
+processor, system, peripheral bus and external memory interface clocks,
+source selection for peripheral clocks and control of power saving
+clock gating mode.
+
+Required properties:
+
+- compatible: Should be "fsl,imx7ulp-scg1".
+- reg : Should contain registers location and length.
+- #clock-cells: Should be <1>.
+- clocks: Should contain the fixed input clocks.
+- clock-names: Should contain the following clock names:
+ "rosc", "sosc", "sirc", "firc", "upll", "mpll".
+
+Peripheral Clock Control (PCC) modules:
+---------------------------------------------------------------------
+The Peripheral Clock Control (PCC) is responsible for clock selection,
+optional division and clock gating mode for peripherals in their
+respected power domain
+
+Required properties:
+- compatible: Should be one of:
+ "fsl,imx7ulp-pcc2",
+ "fsl,imx7ulp-pcc3".
+- reg : Should contain registers location and length.
+- #clock-cells: Should be <1>.
+- clocks: Should contain the fixed input clocks.
+- clock-names: Should contain the following clock names:

+* NXP i.MX8QXP LPCG (Low-Power Clock Gating) Clock bindings
+
+The Low-Power Clock Gate (LPCG) modules contain a local programming
+model to control the clock gates for the peripherals. An LPCG module
+is used to locally gate the clocks for the associated peripheral.
+
+Note:
+This level of clock gating is provided after the clocks are generated
+by the SCU resources and clock controls. Thus even if the clock is
+enabled by these control bits, it might still not be running based
+on the base resource.

TPO TPG110 Panel
================
-This binding builds on the DPI bindings, adding a few properties
-as a superset of a DPI. See panel-dpi.txt for the required DPI
-bindings.
+This panel driver is a component that acts as an intermediary
+between an RGB output and a variety of panels. The panel
+driver is strapped up in electronics to the desired resolution
+and other properties, and has a control interface over 3WIRE
+SPI. By talking to the TPG110 over SPI, the strapped properties
+can be discovered and the hardware is therefore mostly
+self-describing.
+
+ +--------+
+SPI -> | TPO | -> physical display
+RGB -> | TPG110 |
+ +--------+
+
+If some electrical strap or alternate resolution is desired,
+this can be set up by taking software control of the display
+over the SPI interface. The interface can also adjust
+for properties of the display such as gamma correction and
+certain electrical driving levels.
+
+The TPG110 does not know the physical dimensions of the panel
+connected, so this needs to be specified in the device tree.
+
+It requires a GPIO line for control of its reset line.
+
+The serial protocol has line names that resemble I2C but the
+protocol is not I2C but 3WIRE SPI.
Required properties:
-- compatible : "tpo,tpg110"
+- compatible : one of:
+ "ste,nomadik-nhk15-display", "tpo,tpg110"
+ "tpo,tpg110"
- grestb-gpios : panel reset GPIO
-- scen-gpios : serial control enable GPIO
-- scl-gpios : serial control clock line GPIO
-- sda-gpios : serial control data line GPIO
+- width-mm : see display/panel/panel-common.txt
+- height-mm : see display/panel/panel-common.txt
+
+The device needs to be a child of an SPI bus, see
+spi/spi-bus.txt. The SPI child must set the following
+properties:
+- spi-3wire
+- spi-max-frequency = <3000000>;
+as these are characteristics of this device.
-Required nodes:
-- Video port for DPI input, see panel-dpi.txt
-- Panel timing for DPI setup, see panel-dpi.txt
+The device node can contain one 'port' child node with one child
+'endpoint' node, according to the bindings defined in
+media/video-interfaces.txt. This node should describe panel's video bus.

+Intel Service Layer Driver for Stratix10 SoC
+============================================
+Intel Stratix10 SoC is composed of a 64 bit quad-core ARM Cortex A53 hard
+processor system (HPS) and Secure Device Manager (SDM). When the FPGA is
+configured from HPS, there needs to be a way for HPS to notify SDM the
+location and size of the configuration data. Then SDM will get the
+configuration data from that location and perform the FPGA configuration.
+
+To meet the whole system security needs and support virtual machine requesting
+communication with SDM, only the secure world of software (EL3, Exception
+Layer 3) can interface with SDM. All software entities running on other
+exception layers must channel through the EL3 software whenever it needs
+service from SDM.
+
+Intel Stratix10 service layer driver, running at privileged exception level
+(EL1, Exception Layer 1), interfaces with the service providers and provides
+the services for FPGA configuration, QSPI, Crypto and warm reset. Service layer
+driver also manages secure monitor call (SMC) to communicate with secure monitor
+code running in EL3.
+
+Required properties:
+-------------------
+The svc node has the following mandatory properties, must be located under
+the firmware node.
+
+- compatible: "intel,stratix10-svc"
+- method: smc or hvc
+ smc - Secure Monitor Call
+ hvc - Hypervisor Call
+- memory-region:

+Generic device tree bindings for I3C busses
+===========================================
+
+This document describes generic bindings that should be used to describe I3C
+busses in a device tree.
+
+Required properties
+-------------------
+
+- #address-cells - should be <3>. Read more about addresses below.
+- #size-cells - should be <0>.
+- compatible - name of the I3C master controller driving the I3C bus
+
+For other required properties e.g. to describe register sets,
+clocks, etc. check the binding documentation of the specific driver.
+The node describing an I3C bus should be named i3c-master.
+
+Optional properties
+-------------------
+
+These properties may not be supported by all I3C master drivers. Each I3C
+master bindings should specify which of them are supported.
+
+- i3c-scl-hz: frequency of the SCL signal used for I3C transfers.
+ When undefined the core sets it to 12.5MHz.
+
+- i2c-scl-hz: frequency of the SCL signal used for I2C transfers.
+ When undefined, the core looks at LVR (Legacy Virtual Register)
+ values of I2C devices described in the device tree to determine
+ the maximum I2C frequency.
+
+I2C devices
+===========
+
+Each I2C device connected to the bus should be described in a subnode. All
+properties described in Documentation/devicetree/bindings/i2c/i2c.txt are
+valid here, but several new properties have been added.
+
+New constraint on existing properties:
+--------------------------------------
+- reg: contains 3 cells
+ + first cell : still encoding the I2C address
+
+ + second cell: shall be 0
+
+ + third cell: shall encode the I3C LVR (Legacy Virtual Register)
+ bit[31:8]: unused/ignored
+ bit[7:5]: I2C device index. Possible values
+ * 0: I2C device has a 50 ns spike filter
+ * 1: I2C device does not have a 50 ns spike filter but supports high
+ frequency on SCL
+ * 2: I2C device does not have a 50 ns spike filter and is not tolerant
+ to high frequencies
+ * 3-7: reserved
+
+ bit[4]: tell whether the device operates in FM (Fast Mode) or FM+ mode
+ * 0: FM+ mode
+ * 1: FM mode
+
+ bit[3:0]: device type
+ * 0-15: reserved
+
+The I2C node unit-address should always match the first cell of the reg
+property: <device-type>@<i2c-address>.
+
+I3C devices
+===========
+
+All I3C devices are supposed to support DAA (Dynamic Address Assignment), and
+are thus discoverable. So, by default, I3C devices do not have to be described
+in the device tree.
+This being said, one might want to attach extra resources to these devices,
+and those resources may have to be described in the device tree, which in turn
+means we have to describe I3C devices.
+
+Another use case for describing an I3C device in the device tree is when this
+I3C device has a static I2C address and we want to assign it a specific I3C
+dynamic address before the DAA takes place (so that other devices on the bus
+can't take this dynamic address).
+
+The I3C device should be names <device-type>@<static-i2c-address>,<i3c-pid>,
+where device-type is describing the type of device connected on the bus
+(gpio-controller, sensor, ...).
+
+Required properties
+-------------------
+- reg: contains 3 cells
+ + first cell : encodes the static I2C address. Should be 0 if the device does
+ not have one (0 is not a valid I2C address).
+
+ + second and third cells: should encode the ProvisionalID. The second cell
+ contains the manufacturer ID left-shifted by 1.
+ The third cell contains ORing of the part ID
+ left-shifted by 16, the instance ID left-shifted
+ by 12 and the extra information. This encoding is
+ following the PID definition provided by the I3C
+ specification.
+
+Optional properties
+-------------------
+- assigned-address: dynamic address to be assigned to this device. This
+ property is only valid if the I3C device has a static
+ address (first cell of the reg property != 0).
+
+
+Example:
+
+ i3c-master@d040000 {
+ compatible = "cdns,i3c-master";
+ clocks = <&coreclock>, <&i3csysclock>;
+ clock-names = "pclk", "sysclk";
+ interrupts = <3 0>;
+ reg = <0x0d040000 0x1000>;
+ #address-cells = <3>;
+ #size-cells = <0>;
+ i2c-scl-hz = <100000>;
+
+ /* I2C device. */
+ nunchuk: nunchuk@52 {
+ compatible = "nintendo,nunchuk";
+ reg = <0x52 0x0 0x10>;
+ };
+
+ /* I3C device with a static I2C address. */
+ thermal_sensor: sensor@68,39200144004 {
+ reg = <0x68 0x392 0x144004>;
+ assigned-address = <0xa>;
+ };
+
+ /*
+ * I3C device without a static I2C address but requiring
+ * resources described in the DT.
+ */
+ sensor@0,39200154004 {
+ reg = <0x0 0x392 0x154004>;
+ clocks = <&clock_provider 0>;

+Interconnect Provider Device Tree Bindings
+=========================================
+
+The purpose of this document is to define a common set of generic interconnect
+providers/consumers properties.
+
+
+= interconnect providers =
+
+The interconnect provider binding is intended to represent the interconnect
+controllers in the system. Each provider registers a set of interconnect
+nodes, which expose the interconnect related capabilities of the interconnect
+to consumer drivers. These capabilities can be throughput, latency, priority
+etc. The consumer drivers set constraints on interconnect path (or endpoints)
+depending on the use case. Interconnect providers can also be interconnect
+consumers, such as in the case where two network-on-chip fabrics interface
+directly.
+
+Required properties:
+- compatible : contains the interconnect provider compatible string
+- #interconnect-cells : number of cells in a interconnect specifier needed to
+ encode the interconnect node id
+
+Example:
+
+ snoc: interconnect@580000 {
+ compatible = "qcom,msm8916-snoc";
+ #interconnect-cells = <1>;
+ reg = <0x580000 0x14000>;
+ clock-names = "bus_clk", "bus_a_clk";
+ clocks = <&rpmcc RPM_SMD_SNOC_CLK>,
+ <&rpmcc RPM_SMD_SNOC_A_CLK>;
+ };
+
+
+= interconnect consumers =
+
+The interconnect consumers are device nodes which dynamically express their
+bandwidth requirements along interconnect paths they are connected to. There
+can be multiple interconnect providers on a SoC and the consumer may consume
+multiple paths from different providers depending on use case and the
+components it has to interact with.
+
+Required properties:
+interconnects : Pairs of phandles and interconnect provider specifier to denote
+ the edge source and destination ports of the interconnect path.
+
+Optional properties:
+interconnect-names : List of interconnect path name strings sorted in the same
+ order as the interconnects property. Consumers drivers will use
+ interconnect-names to match interconnect paths with interconnect
+ specifier pairs.
+
+Example:
+
+ sdhci@7864000 {
+ ...
+ interconnects = <&pnoc MASTER_SDCC_1 &bimc SLAVE_EBI_CH0>;
+ interconnect-names = "sdhc-mem";
+ };

-* ARM Generic Interrupt Controller, version 3
-
-AArch64 SMP cores are often associated with a GICv3, providing Private
-Peripheral Interrupts (PPI), Shared Peripheral Interrupts (SPI),
-Software Generated Interrupts (SGI), and Locality-specific Peripheral
-Interrupts (LPI).
-
-Main node required properties:
-
-- compatible : should at least contain "arm,gic-v3".
-- interrupt-controller : Identifies the node as an interrupt controller
-- #interrupt-cells : Specifies the number of cells needed to encode an
- interrupt source. Must be a single cell with a value of at least 3.
- If the system requires describing PPI affinity, then the value must
- be at least 4.
-
- The 1st cell is the interrupt type; 0 for SPI interrupts, 1 for PPI
- interrupts. Other values are reserved for future use.
-
- The 2nd cell contains the interrupt number for the interrupt type.
- SPI interrupts are in the range [0-987]. PPI interrupts are in the
- range [0-15].
-
- The 3rd cell is the flags, encoded as follows:
- bits[3:0] trigger type and level flags.
- 1 = edge triggered
- 4 = level triggered
-
- The 4th cell is a phandle to a node describing a set of CPUs this
- interrupt is affine to. The interrupt must be a PPI, and the node
- pointed must be a subnode of the "ppi-partitions" subnode. For
- interrupt types other than PPI or PPIs that are not partitionned,
- this cell must be zero. See the "ppi-partitions" node description
- below.
-
- Cells 5 and beyond are reserved for future use and must have a value
- of 0 if present.
-
-- reg : Specifies base physical address(s) and size of the GIC
- registers, in the following order:
- - GIC Distributor interface (GICD)
- - GIC Redistributors (GICR), one range per redistributor region
- - GIC CPU interface (GICC)
- - GIC Hypervisor interface (GICH)
- - GIC Virtual CPU interface (GICV)
-
- GICC, GICH and GICV are optional.
-
-- interrupts : Interrupt source of the VGIC maintenance interrupt.
-
-Optional
-
-- redistributor-stride : If using padding pages, specifies the stride
- of consecutive redistributors. Must be a multiple of 64kB.
-
-- #redistributor-regions: The number of independent contiguous regions
- occupied by the redistributors. Required if more than one such
- region is present.
-
-- msi-controller: Boolean property. Identifies the node as an MSI
- controller. Only present if the Message Based Interrupt
- functionnality is being exposed by the HW, and the mbi-ranges
- property present.
-
-- mbi-ranges: A list of pairs <intid span>, where "intid" is the first
- SPI of a range that can be used an MBI, and "span" the size of that
- range. Multiple ranges can be provided. Requires "msi-controller" to
- be set.
-
-- mbi-alias: Address property. Base address of an alias of the GICD
- region containing only the {SET,CLR}SPI registers to be used if
- isolation is required, and if supported by the HW.
-
-Sub-nodes:
-
-PPI affinity can be expressed as a single "ppi-partitions" node,
-containing a set of sub-nodes, each with the following property:
-- affinity: Should be a list of phandles to CPU nodes (as described in
-Documentation/devicetree/bindings/arm/cpus.txt).
-
-GICv3 has one or more Interrupt Translation Services (ITS) that are
-used to route Message Signalled Interrupts (MSI) to the CPUs.
-
-These nodes must have the following properties:
-- compatible : Should at least contain "arm,gic-v3-its".
-- msi-controller : Boolean property. Identifies the node as an MSI controller
-- #msi-cells: Must be <1>. The single msi-cell is the DeviceID of the device
- which will generate the MSI.
-- reg: Specifies the base physical address and size of the ITS
- registers.
-
-Optional:
-- socionext,synquacer-pre-its: (u32, u32) tuple describing the untranslated
- address and size of the pre-ITS window.
-
-The main GIC node must contain the appropriate #address-cells,
-#size-cells and ranges properties for the reg property of all ITS
-nodes.

- interrupts.
-
- The 2nd cell contains the interrupt number for the interrupt type.
- SPI interrupts are in the range [0-987]. PPI interrupts are in the
- range [0-15].
-
- The 3rd cell is the flags, encoded as follows:
- bits[3:0] trigger type and level flags.
- 1 = low-to-high edge triggered
- 2 = high-to-low edge triggered (invalid for SPIs)
- 4 = active high level-sensitive
- 8 = active low level-sensitive (invalid for SPIs).
- bits[15:8] PPI interrupt cpu mask. Each bit corresponds to each of
- the 8 possible cpus attached to the GIC. A bit set to '1' indicated
- the interrupt is wired to that CPU. Only valid for PPI interrupts.
- Also note that the configurability of PPI interrupts is IMPLEMENTATION
- DEFINED and as such not guaranteed to be present (most SoC available
- in 2014 seem to ignore the setting of this flag and use the hardware
- default value).
-
-- reg : Specifies base physical address(s) and size of the GIC registers. The
- first region is the GIC distributor register base and size. The 2nd region is
- the GIC cpu interface register base and size.
-
-Optional
-- interrupts : Interrupt source of the parent interrupt controller on
- secondary GICs, or VGIC maintenance interrupt on primary GIC (see
- below).
-
-- cpu-offset : per-cpu offset within the distributor and cpu interface
- regions, used when the GIC doesn't have banked registers. The offset is
- cpu-offset * cpu-nr.
-
-- clocks : List of phandle and clock-specific pairs, one for each entry
- in clock-names.
-- clock-names : List of names for the GIC clock input(s). Valid clock names
- depend on the GIC variant:
- "ic_clk" (for "arm,arm11mp-gic")
- "PERIPHCLKEN" (for "arm,cortex-a15-gic")
- "PERIPHCLK", "PERIPHCLKEN" (for "arm,cortex-a9-gic")
- "clk" (for "arm,gic-400" and "nvidia,tegra210")
- "gclk" (for "arm,pl390")
-
-- power-domains : A phandle and PM domain specifier as defined by bindings of
- the power controller specified by phandle, used when the GIC
- is part of a Power or Clock Domain.
-
-
-Example:
-
- intc: interrupt-controller@fff11000 {
- compatible = "arm,cortex-a9-gic";
- #interrupt-cells = <3>;
- #address-cells = <1>;
- interrupt-controller;
- reg = <0xfff11000 0x1000>,
- <0xfff10100 0x100>;
- };
-
-
-* GIC virtualization extensions (VGIC)
-
-For ARM cores that support the virtualization extensions, additional
-properties must be described (they only exist if the GIC is the
-primary interrupt controller).
-
-Required properties:
-
-- reg : Additional regions specifying the base physical address and
- size of the VGIC registers. The first additional region is the GIC
- virtual interface control register base and size. The 2nd additional
- region is the GIC virtual cpu interface register base and size.
-
-- interrupts : VGIC maintenance interrupt.
-
-Example:
-
- interrupt-controller@2c001000 {
- compatible = "arm,cortex-a15-gic";
- #interrupt-cells = <3>;
- interrupt-controller;
- reg = <0x2c001000 0x1000>,

- <0x2c004000 0x2000>,
- <0x2c006000 0x2000>;
- interrupts = <1 9 0xf04>;
- };
-
-
-* GICv2m extension for MSI/MSI-x support (Optional)
-
-Certain revisions of GIC-400 supports MSI/MSI-x via V2M register frame(s).
-This is enabled by specifying v2m sub-node(s).
-
-Required properties:
-
-- compatible : The value here should contain "arm,gic-v2m-frame".
-
-- msi-controller : Identifies the node as an MSI controller.
-
-- reg : GICv2m MSI interface register base and size
-
-Optional properties:
-
-- arm,msi-base-spi : When the MSI_TYPER register contains an incorrect
- value, this property should contain the SPI base of
- the MSI frame, overriding the HW value.
-
-- arm,msi-num-spis : When the MSI_TYPER register contains an incorrect
- value, this property should contain the number of
- SPIs assigned to the frame, overriding the HW value.
-
-Example:

+* Pattern format for LED pattern trigger
+
+The pattern is given by a series of tuples, of brightness and duration (ms).
+The LED is expected to traverse the series and each brightness value for the
+specified duration. Duration of 0 means brightness should immediately change to
+new value, and writing malformed pattern deactivates any active one.
+
+1. For gradual dimming, the dimming interval now is set as 50 milliseconds. So
+the tuple with duration less than dimming interval (50ms) is treated as a step
+change of brightness, i.e. the subsequent brightness will be applied without
+adding intervening dimming intervals.
+
+The gradual dimming format of the software pattern values should be:
+"brightness_1 duration_1 brightness_2 duration_2 brightness_3 duration_3 ...".
+For example (using sysfs interface):
+
+echo 0 1000 255 2000 > pattern
+
+It will make the LED go gradually from zero-intensity to max (255) intensity in
+1000 milliseconds, then back to zero intensity in 2000 milliseconds:
+
+LED brightness
+ ^
+255-| / \ / \ /
+ | / \ / \ /
+ | / \ / \ /
+ | / \ / \ /
+ 0-| / \/ \/
+ +---0----1----2----3----4----5----6------------> time (s)
+
+2. To make the LED go instantly from one brightness value to another, we should
+use zero-time lengths (the brightness must be same as the previous tuple's). So
+the format should be: "brightness_1 duration_1 brightness_1 0 brightness_2
+duration_2 brightness_2 0 ...".
+For example (using sysfs interface):
+
+echo 0 1000 0 0 255 2000 255 0 > pattern
+
+It will make the LED stay off for one second, then stay at max brightness for
+two seconds:

+RedBoot FLASH Image System (FIS) Partitions
+===========================================
+
+The FLASH Image System (FIS) directory is a flash description
+format closely associated with the RedBoot boot loader.
+
+It uses one single flash eraseblock in the flash to store an index of
+all images in the flash.
+
+This block size will vary depending on flash but is typically
+32 KB in size.
+
+Required properties:
+- compatible : (required) must be "redboot-fis"
+- fis-index-block : (required) a index to the eraseblock containing
+ the FIS directory on this device. On a flash memory with 32KB
+ eraseblocks, 0 means the first eraseblock at 0x00000000, 1 means the
+ second eraseblock at 0x00008000 and so on.

+ partitions {
+ compatible = "redboot-fis";
+ fis-index-block = <0>;

+* ENETC ethernet device tree bindings
+
+Depending on board design and ENETC port type (internal or

+below device tree bindings.
+
+Required properties:
+
+- reg : Specifies PCIe Device Number and Function
+ Number of the ENETC endpoint device, according
+ to parent node bindings.
+- compatible : Should be "fsl,enetc".
+
+1) The ENETC external port is connected to a MDIO configurable phy:
+
+In this case, the ENETC node should include a "mdio" sub-node
+that in turn should contain the "ethernet-phy" node describing the
+external phy. Below properties are required, their bindings
+already defined in ethernet.txt or phy.txt, under
+Documentation/devicetree/bindings/net/*.
+
+Required:
+
+- phy-handle : Phandle to a PHY on the MDIO bus.
+ Defined in ethernet.txt.
+
+- phy-connection-type : Defined in ethernet.txt.
+
+- mdio : "mdio" node, defined in mdio.txt.
+
+- ethernet-phy : "ethernet-phy" node, defined in phy.txt.
+
+Example:
+
+ ethernet@0,0 {
+ compatible = "fsl,enetc";
+ reg = <0x000000 0 0 0 0>;
+ phy-handle = <&sgmii_phy0>;

+ mdio {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ sgmii_phy0: ethernet-phy@2 {
+ reg = <0x2>;
+ };
+ };
+ };
+
+2) The ENETC port is an internal port or has a fixed-link external
+connection:
+
+In this case, the ENETC port node defines a fixed link connection,
+as specified by "fixed-link.txt", under
+Documentation/devicetree/bindings/net/*.
+
+Required:
+
+- fixed-link : "fixed-link" node, defined in "fixed-link.txt".
+
+Example:
+ ethernet@0,2 {

+CPSW Port's Interface Mode Selection PHY Tree Bindings
+-----------------------------------------------
+
+TI am335x/am437x/dra7(am5)/dm814x CPSW3G Ethernet Subsystem supports
+two 10/100/1000 Ethernet ports with selectable G/MII, RMII, and RGMII interfaces.
+The interface mode is selected by configuring the MII mode selection register(s)
+(GMII_SEL) in the System Control Module chapter (SCM). GMII_SEL register(s) and
+bit fields placement in SCM are different between SoCs while fields meaning
+is the same.

+Actions Semi S700 Pin Controller
+
+This binding describes the pin controller found in the S700 SoC.
+
+Required Properties:
+
+- compatible: Should be "actions,s700-pinctrl"
+- reg: Should contain the register base address and size of
+ the pin controller.
+- clocks: phandle of the clock feeding the pin controller
+- gpio-controller: Marks the device node as a GPIO controller.
+- gpio-ranges: Specifies the mapping between gpio controller and
+ pin-controller pins.
+- #gpio-cells: Should be two. The first cell is the gpio pin number
+ and the second cell is used for optional parameters.
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells: Specifies the number of cells needed to encode an
+ interrupt. Shall be set to 2. The first cell
+ defines the interrupt number, the second encodes
+ the trigger flags described in
+ bindings/interrupt-controller/interrupts.txt
+- interrupts: The interrupt outputs from the controller. There is one GPIO
+ interrupt per GPIO bank. The number of interrupts listed depends
+ on the number of GPIO banks on the SoC. The interrupts must be
+ ordered by bank, starting with bank 0.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+The pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+PIN CONFIGURATION NODES:
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+Pinmux functions are available only for the pin groups while pinconf
+parameters are available for both pin groups and individual pins.
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:

+Pin multiplexing and GPIO configuration is performed on a per-pin basis.
+Each port features up to 8 pins, each of them configurable for GPIO
+function (port mode) or in alternate function mode.
+Up to 8 different alternate function modes exist for each single pin.

+ - pinmux:
+ integer array representing pin number and pin multiplexing configuration.
+ When a pin has to be configured in alternate function mode, use this
+ property to identify the pin by its global index, and provide its
+ alternate function configuration number along with it.
+ When multiple pins are required to be configured as part of the same
+ alternate function they shall be specified as members of the same
+ argument list of a single "pinmux" property.
+ Helper macros to ease assembling the pin index from its position
+ (port where it sits on and pin number) and alternate function identifier
+ are provided by the pin controller header file at:
+ <dt-bindings/pinctrl/r7s9210-pinctrl.h>
+ Integers values in "pinmux" argument list are assembled as:
+ ((PORT * 8 + PIN) | MUX_FUNC << 16)
+
+ Example: Board specific pins configuration
+
+ &pinctrl {
+ /* Serial Console */
+ scif4_pins: serial4 {
+ pinmux = <RZA2_PINMUX(PORT9, 0, 4)>, /* TxD4 */

+Cirrus Logic Lochnagar Audio Development Board
+
+Lochnagar is an evaluation and development board for Cirrus Logic
+Smart CODEC and Amp devices. It allows the connection of most Cirrus
+Logic devices on mini-cards, as well as allowing connection of
+various application processor systems to provide a full evaluation
+platform. Audio system topology, clocking and power can all be
+controlled through the Lochnagar, allowing the device under test
+to be used in a variety of possible use cases.
+
+This binding document describes the binding for the regulator portion
+of the driver.
+
+Also see these documents for generic binding information:
+ [1] Regulator: ../regulator/regulator.txt

+ - compatible : One of the following strings:
+ "cirrus,lochnagar2-vddcore"
+ - SYSVDD-supply: Primary power supply for the Lochnagar.

+Regulator driver for MAX77650 PMIC from Maxim Integrated.
+
+This module is part of the MAX77650 MFD device. For more details
+see Documentation/devicetree/bindings/mfd/max77650.txt.
+
+The regulator controller is represented as a sub-node of the PMIC node
+on the device tree.
+
+The device has a single LDO regulator and a SIMO buck-boost regulator with
+three independent power rails.
+
+Required properties:
+--------------------
+- compatible: Must be "maxim,max77650-regulator"
+
+Each rail must be instantiated under the regulators subnode of the top PMIC
+node. Up to four regulators can be defined. For standard regulator properties
+refer to Documentation/devicetree/bindings/regulator/regulator.txt.
+
+Available regulator compatible strings are: "ldo", "sbb0", "sbb1", "sbb2".
+
+Example:
+--------
+
+ regulators {

+Generic device tree bindings for Real Time Clock devices
+========================================================
+
+This document describes generic bindings which can be used to describe Real Time
+Clock devices in a device tree.
+
+Required properties
+-------------------
+
+- compatible : name of RTC device following generic names recommended practice.
+
+For other required properties e.g. to describe register sets,
+clocks, etc. check the binding documentation of the specific driver.
+
+Optional properties
+-------------------
+
+- start-year : if provided, the default hardware range supported by the RTC is
+ shifted so the first usable year is the specified one.
+
+The following properties may not be supported by all drivers. However, if a
+driver wants to support one of the below features, it should adapt the bindings
+below.
+- trickle-resistor-ohms : Selected resistor for trickle charger. Should be given
+ if trickle charger should be enabled
+- trickle-diode-disable : Do not use internal trickle charger diode Should be
+ given if internal trickle charger diode should be
+ disabled
+- wakeup-source : Enables wake up of host system on alarm
+- quartz-load-femtofarads : The capacitive load of the quartz(x-tal),
+ expressed in femto Farad (fF).
+ The default value shall be listed (if optional),
+ and likewise all valid values.
+
+Trivial RTCs
+------------
+
+This is a list of trivial RTC devices that have simple device tree
+bindings, consisting only of a compatible field, an address and
+possibly an interrupt line.

- not present then the register offsets are not shifted.
-- reg-io-width : the size (in bytes) of the IO accesses that should be
- performed on the device. If this property is not present then single byte
- accesses are used.
-- dcd-override : Override the DCD modem status signal. This signal will always

-- always-on : a boolean property. If present, the timer is powered through an
- always-on power domain, therefore it never loses context.
-
-- fsl,erratum-a008585 : A boolean property. Indicates the presence of
- QorIQ erratum A-008585, which says that reading the counter is
- unreliable unless the same value is returned by back-to-back reads.
- This also affects writes to the tval register, due to the implicit

-
-- hisilicon,erratum-161010101 : A boolean property. Indicates the
- presence of Hisilicon erratum 161010101, which says that reading the
- counters is unreliable in some cases, and reads may return a value 32
- beyond the correct value. This also affects writes to the tval
- registers, due to the implicit counter read.
-
-** Optional properties:
-
-- arm,cpu-registers-not-fw-configured : Firmware does not initialize
- any of the generic timer CPU registers, which contain their

- systems which follow the ARMv7 architected reset values.
-
-- arm,no-tick-in-suspend : The main counter does not tick when the system is in
- low-power system suspend on some SoCs. This behavior does not match the
- Architecture Reference Manual's specification that the system counter "must

-
-Example:
-
- timer {

- <1 10 0xf08>;
- clock-frequency = <100000000>;

-
-** Memory mapped timer node properties:
-
-- compatible : Should at least contain "arm,armv7-timer-mem".
-
-- clock-frequency : The frequency of the main counter, in Hz. Should be present
- only when firmware has not configured the MMIO CNTFRQ registers.
-
-- reg : The control frame base address.
-
-Note that #address-cells, #size-cells, and ranges shall be present to ensure
-the CPU can address a frame's registers.
-
-A timer node has up to 8 frame sub-nodes, each with the following properties:
-
-- frame-number: 0 to 7.
-
-- interrupts : Interrupt list for physical and virtual timers in that order.
- The virtual timer interrupt is optional.
-
-- reg : The first and second view base addresses in that order. The second view
- base address is optional.
-
-- status : "disabled" indicates the frame is not available for use. Optional.

+# Writing DeviceTree Bindings in json-schema
+
+Devicetree bindings are written using json-schema vocabulary. Schema files are
+written in a JSON compatible subset of YAML. YAML is used instead of JSON as it
+considered more human readable and has some advantages such as allowing
+comments (Prefixed with '#').
+
+## Schema Contents
+
+Each schema doc is a structured json-schema which is defined by a set of
+top-level properties. Generally, there is one binding defined per file. The
+top-level json-schema properties used are:
+
+- __$id__ - A json-schema unique identifier string. The string must be a valid
+URI typically containing the binding's filename and path. For DT schema, it must
+begin with "http://devicetree.org/schemas/". The URL is used in constructing
+references to other files specified in schema "$ref" properties. A $ref values
+with a leading '/' will have the hostname prepended. A $ref value a relative
+path or filename only will be prepended with the hostname and path components
+of the current schema file's '$id' value. A URL is used even for local files,
+but there may not actually be files present at those locations.
+
+- __$schema__ - Indicates the meta-schema the schema file adheres to.
+
+- __title__ - A one line description on the contents of the binding schema.
+
+- __maintainers__ - A DT specific property. Contains a list of email address(es)
+for maintainers of this binding.
+
+- __description__ - Optional. A multi-line text block containing any detailed
+information about this binding. It should contain things such as what the block
+or device does, standards the device conforms to, and links to datasheets for
+more information.
+
+- __select__ - Optional. A json-schema used to match nodes for applying the
+schema. By default without 'select', nodes are matched against their possible
+compatible string values or node name. Most bindings should not need select.
+
+- __allOf__ - Optional. A list of other schemas to include. This is used to
+include other schemas the binding conforms to. This may be schemas for a
+particular class of devices such as I2C or SPI controllers.
+
+- __properties__ - A set of sub-schema defining all the DT properties for the
+binding. The exact schema syntax depends on whether properties are known,
+common properties (e.g. 'interrupts') or are binding/vendor specific properties.
+
+ A property can also define a child DT node with child properties defined
+under it.
+
+ For more details on properties sections, see 'Property Schema' section.
+
+- __patternProperties__ - Optional. Similar to 'properties', but names are regex.
+
+- __required__ - A list of DT properties from the 'properties' section that
+must always be present.
+
+- __examples__ - Optional. A list of one or more DTS hunks implementing the
+binding. Note: YAML doesn't allow leading tabs, so spaces must be used instead.
+
+Unless noted otherwise, all properties are required.
+
+## Property Schema
+
+The 'properties' section of the schema contains all the DT properties for a
+binding. Each property contains a set of constraints using json-schema
+vocabulary for that property. The properties schemas are what is used for
+validation of DT files.
+
+For common properties, only additional constraints not covered by the common
+binding schema need to be defined such as how many values are valid or what
+possible values are valid.
+
+Vendor specific properties will typically need more detailed schema. With the
+exception of boolean properties, they should have a reference to a type in
+schemas/types.yaml. A "description" property is always required.
+
+The Devicetree schemas don't exactly match the YAML encoded DT data produced by
+dtc. They are simplified to make them more compact and avoid a bunch of
+boilerplate. The tools process the schema files to produce the final schema for
+validation. There are currently 2 transformations the tools perform.
+
+The default for arrays in json-schema is they are variable sized and allow more
+entries than explicitly defined. This can be restricted by defining 'minItems',
+'maxItems', and 'additionalItems'. However, for DeviceTree Schemas, a fixed
+size is desired in most cases, so these properties are added based on the
+number of entries in an 'items' list.
+
+The YAML Devicetree format also makes all string values an array and scalar
+values a matrix (in order to define groupings) even when only a single value
+is present. Single entries in schemas are fixed up to match this encoding.
+
+## Testing
+
+### Dependencies
+
+The DT schema project must be installed in order to validate the DT schema
+binding documents and validate DTS files using the DT schema. The DT schema
+project can be installed with pip:
+
+`pip3 install git+https://github.com/robherring/yaml-bindings.git@master`
+
+dtc must also be built with YAML output support enabled. This requires that
+libyaml and its headers be installed on the host system.
+
+### Running checks
+
+The DT schema binding documents must be validated using the meta-schema (the
+schema for the schema) to ensure they are both valid json-schema and valid
+binding schema. All of the DT binding documents can be validated using the
+`dt_binding_check` target:
+
+`make dt_binding_check`
+
+In order to perform validation of DT source files, use the `dtbs_check` target:
+
+`make dtbs_check`
+
+This will first run the `dt_binding_check` which generates the processed schema.
+
+It is also possible to run checks with a single schema file by setting the
+'DT_SCHEMA_FILES' variable to a specific schema file.
+
+`make dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/trivial-devices.yaml`

+Moreover, managed device links cannot be deleted directly. They are deleted

+However, stateless device links (i.e. device links with ``DL_FLAG_STATELESS``
+set) are expected to be removed by whoever called :c:func:`device_link_add()`
+to add them with the help of either :c:func:`device_link_del()` or
+:c:func:`device_link_remove()`.
+
+Passing ``DL_FLAG_RPM_ACTIVE`` along with ``DL_FLAG_STATELESS`` to
+:c:func:`device_link_add()` may cause the PM-runtime usage counter of the
+supplier device to remain nonzero after a subsequent invocation of either
+:c:func:`device_link_del()` or :c:func:`device_link_remove()` to remove the
+device link returned by it. This happens if :c:func:`device_link_add()` is
+called twice in a row for the same consumer-supplier pair without removing the

+of the supplier to drop on an attempt to remove the link may cause it to be
+suspended while the consumer is still PM-runtime-active and that has to be
+avoided. [To work around this limitation it is sufficient to let the consumer

+Part 5 - Handling channel allocation
+====================================
+
+Allocating Channels
+-------------------
+
+Channels are required to be configured prior to starting the test run.
+Attempting to run the test without configuring the channels will fail.
+
+Example::
+
+ % echo 1 > /sys/module/dmatest/parameters/run
+ dmatest: Could not start test, no channels configured
+
+Channels are registered using the "channel" parameter. Channels can be requested by their
+name, once requested, the channel is registered and a pending thread is added to the test list.
+
+Example::
+
+ % echo dma0chan2 > /sys/module/dmatest/parameters/channel
+ dmatest: Added 1 threads using dma0chan2
+
+More channels can be added by repeating the example above.
+Reading back the channel parameter will return the name of last channel that was added successfully.
+
+Example::
+
+ % echo dma0chan1 > /sys/module/dmatest/parameters/channel
+ dmatest: Added 1 threads using dma0chan1
+ % echo dma0chan2 > /sys/module/dmatest/parameters/channel
+ dmatest: Added 1 threads using dma0chan2
+ % cat /sys/module/dmatest/parameters/channel
+ dma0chan2
+
+Another method of requesting channels is to request a channel with an empty string, Doing so
+will request all channels available to be tested:
+
+Example::
+
+ % echo "" > /sys/module/dmatest/parameters/channel
+ dmatest: Added 1 threads using dma0chan0
+ dmatest: Added 1 threads using dma0chan3
+ dmatest: Added 1 threads using dma0chan4
+ dmatest: Added 1 threads using dma0chan5
+ dmatest: Added 1 threads using dma0chan6
+ dmatest: Added 1 threads using dma0chan7
+ dmatest: Added 1 threads using dma0chan8
+
+At any point during the test configuration, reading the "test_list" parameter will
+print the list of currently pending tests.
+
+Example::
+
+ % cat /sys/module/dmatest/parameters/test_list
+ dmatest: 1 threads using dma0chan0
+ dmatest: 1 threads using dma0chan3
+ dmatest: 1 threads using dma0chan4
+ dmatest: 1 threads using dma0chan5
+ dmatest: 1 threads using dma0chan6
+ dmatest: 1 threads using dma0chan7
+ dmatest: 1 threads using dma0chan8
+
+Note: Channels will have to be configured for each test run as channel configurations do not
+carry across to the next test run.
+
+Releasing Channels
+-------------------
+
+Channels can be freed by setting run to 0.
+
+Example::
+ % echo dma0chan1 > /sys/module/dmatest/parameters/channel
+ dmatest: Added 1 threads using dma0chan1
+ % cat /sys/class/dma/dma0chan1/in_use
+ 1
+ % echo 0 > /sys/module/dmatest/parameters/run
+ % cat /sys/class/dma/dma0chan1/in_use
+ 0
+
+Channels allocated by previous test runs are automatically freed when a new
+channel is requested after completing a successful test run.

+Disclaimer
+==========
+
+This chapter will focus on aspects that matter to software developers. For
+everything hardware related (like how things are transmitted on the bus, how
+collisions are prevented, ...) please have a look at the I3C specification.
+
+This document is just a brief introduction to the I3C protocol and the concepts
+it brings to the table. If you need more information, please refer to the MIPI
+I3C specification (can be downloaded here
+http://resources.mipi.org/mipi-i3c-v1-download).
+
+Introduction
+============
+
+The I3C (pronounced 'eye-three-see') is a MIPI standardized protocol designed
+to overcome I2C limitations (limited speed, external signals needed for
+interrupts, no automatic detection of the devices connected to the bus, ...)
+while remaining power-efficient.
+
+I3C Bus
+=======
+
+An I3C bus is made of several I3C devices and possibly some I2C devices as
+well, but let's focus on I3C devices for now.
+
+An I3C device on the I3C bus can have one of the following roles:
+
+* Master: the device is driving the bus. It's the one in charge of initiating
+ transactions or deciding who is allowed to talk on the bus (slave generated
+ events are possible in I3C, see below).
+* Slave: the device acts as a slave, and is not able to send frames to another
+ slave on the bus. The device can still send events to the master on
+ its own initiative if the master allowed it.
+
+I3C is a multi-master protocol, so there might be several masters on a bus,
+though only one device can act as a master at a given time. In order to gain
+bus ownership, a master has to follow a specific procedure.
+
+Each device on the I3C bus has to be assigned a dynamic address to be able to
+communicate. Until this is done, the device should only respond to a limited
+set of commands. If it has a static address (also called legacy I2C address),
+the device can reply to I2C transfers.
+
+In addition to these per-device addresses, the protocol defines a broadcast
+address in order to address all devices on the bus.
+
+Once a dynamic address has been assigned to a device, this address will be used
+for any direct communication with the device. Note that even after being
+assigned a dynamic address, the device should still process broadcast messages.
+
+I3C Device discovery
+====================
+
+The I3C protocol defines a mechanism to automatically discover devices present
+on the bus, their capabilities and the functionalities they provide. In this
+regard I3C is closer to a discoverable bus like USB than it is to I2C or SPI.
+
+The discovery mechanism is called DAA (Dynamic Address Assignment), because it
+not only discovers devices but also assigns them a dynamic address.
+
+During DAA, each I3C device reports 3 important things:
+
+* BCR: Bus Characteristic Register. This 8-bit register describes the device bus
+ related capabilities
+* DCR: Device Characteristic Register. This 8-bit register describes the
+ functionalities provided by the device
+* Provisional ID: A 48-bit unique identifier. On a given bus there should be no
+ Provisional ID collision, otherwise the discovery mechanism may fail.
+
+I3C slave events
+================
+
+The I3C protocol allows slaves to generate events on their own, and thus allows
+them to take temporary control of the bus.
+
+This mechanism is called IBI for In Band Interrupts, and as stated in the name,
+it allows devices to generate interrupts without requiring an external signal.
+
+During DAA, each device on the bus has been assigned an address, and this
+address will serve as a priority identifier to determine who wins if 2 different
+devices are generating an interrupt at the same moment on the bus (the lower the
+dynamic address the higher the priority).
+
+Masters are allowed to inhibit interrupts if they want to. This inhibition
+request can be broadcast (applies to all devices) or sent to a specific
+device.
+
+I3C Hot-Join
+============
+
+The Hot-Join mechanism is similar to USB hotplug. This mechanism allows
+slaves to join the bus after it has been initialized by the master.
+
+This covers the following use cases:
+
+* the device is not powered when the bus is probed
+* the device is hotplugged on the bus through an extension board
+
+This mechanism is relying on slave events to inform the master that a new
+device joined the bus and is waiting for a dynamic address.
+
+The master is then free to address the request as it wishes: ignore it or
+assign a dynamic address to the slave.
+
+I3C transfer types
+==================
+
+If you omit SMBus (which is just a standardization on how to access registers
+exposed by I2C devices), I2C has only one transfer type.
+
+I3C defines 3 different classes of transfer in addition to I2C transfers which
+are here for backward compatibility with I2C devices.
+
+I3C CCC commands
+----------------
+
+CCC (Common Command Code) commands are meant to be used for anything that is
+related to bus management and all features that are common to a set of devices.
+
+CCC commands contain an 8-bit CCC ID describing the command that is executed.
+The MSB of this ID specifies whether this is a broadcast command (bit7 = 0) or a
+unicast one (bit7 = 1).
+
+The command ID can be followed by a payload. Depending on the command, this
+payload is either sent by the master sending the command (write CCC command),
+or sent by the slave receiving the command (read CCC command). Of course, read
+accesses only apply to unicast commands.
+Note that, when sending a CCC command to a specific device, the device address
+is passed in the first byte of the payload.
+
+The payload length is not explicitly passed on the bus, and should be extracted
+from the CCC ID.
+
+Note that vendors can use a dedicated range of CCC IDs for their own commands
+(0x61-0x7f and 0xe0-0xef).
+
+I3C Private SDR transfers
+-------------------------
+
+Private SDR (Single Data Rate) transfers should be used for anything that is
+device specific and does not require high transfer speed.
+
+It is the equivalent of I2C transfers but in the I3C world. Each transfer is
+passed the device address (dynamic address assigned during DAA), a payload
+and a direction.
+
+The only difference with I2C is that the transfer is much faster (typical clock
+frequency is 12.5MHz).
+
+I3C HDR commands
+----------------
+
+HDR commands should be used for anything that is device specific and requires
+high transfer speed.
+
+The first thing attached to an HDR command is the HDR mode. There are currently
+3 different modes defined by the I3C specification (refer to the specification
+for more details):
+
+* HDR-DDR: Double Data Rate mode
+* HDR-TSP: Ternary Symbol Pure. Only usable on busses with no I2C devices
+* HDR-TSL: Ternary Symbol Legacy. Usable on busses with I2C devices
+
+When sending an HDR command, the whole bus has to enter HDR mode, which is done
+using a broadcast CCC command.
+Once the bus has entered a specific HDR mode, the master sends the HDR command.
+An HDR command is made of:
+
+* one 16-bits command word in big endian
+* N 16-bits data words in big endian
+
+Those words may be wrapped with specific preambles/post-ambles which depend on
+the chosen HDR mode and are detailed here (see the specification for more
+details).
+
+The 16-bits command word is made of:
+
+* bit[15]: direction bit, read is 1, write is 0
+* bit[14:8]: command code. Identifies the command being executed, the amount of
+ data words and their meaning
+* bit[7:1]: I3C address of the device this command is addressed to
+* bit[0]: reserved/parity-bit
+
+Backward compatibility with I2C devices
+=======================================
+
+The I3C protocol has been designed to be backward compatible with I2C devices.
+This backward compatibility allows one to connect a mix of I2C and I3C devices
+on the same bus, though, in order to be really efficient, I2C devices should
+be equipped with 50 ns spike filters.
+
+I2C devices can't be discovered like I3C ones and have to be statically
+declared. In order to let the master know what these devices are capable of
+(both in terms of bus related limitations and functionalities), the software
+has to provide some information, which is done through the LVR (Legacy I2C
+Virtual Register).

+
+
+CPU Idle Time Management Subsystem
+==================================
+
+Every time one of the logical CPUs in the system (the entities that appear to
+fetch and execute instructions: hardware threads, if present, or processor
+cores) is idle after an interrupt or equivalent wakeup event, which means that
+there are no tasks to run on it except for the special "idle" task associated
+with it, there is an opportunity to save energy for the processor that it
+belongs to. That can be done by making the idle logical CPU stop fetching
+instructions from memory and putting some of the processor's functional units
+depended on by it into an idle state in which they will draw less power.
+
+However, there may be multiple different idle states that can be used in such a
+situation in principle, so it may be necessary to find the most suitable one
+(from the kernel perspective) and ask the processor to use (or "enter") that
+particular idle state. That is the role of the CPU idle time management
+subsystem in the kernel, called ``CPUIdle``.
+
+The design of ``CPUIdle`` is modular and based on the code duplication avoidance
+principle, so the generic code that in principle need not depend on the hardware
+or platform design details in it is separate from the code that interacts with
+the hardware. It generally is divided into three categories of functional
+units: *governors* responsible for selecting idle states to ask the processor
+to enter, *drivers* that pass the governors' decisions on to the hardware and
+the *core* providing a common framework for them.
+
+
+CPU Idle Time Governors
+=======================
+
+A CPU idle time (``CPUIdle``) governor is a bundle of policy code invoked when
+one of the logical CPUs in the system turns out to be idle. Its role is to
+select an idle state to ask the processor to enter in order to save some energy.
+
+``CPUIdle`` governors are generic and each of them can be used on any hardware
+platform that the Linux kernel can run on. For this reason, data structures
+operated on by them cannot depend on any hardware architecture or platform
+design details as well.
+
+The governor itself is represented by a |struct cpuidle_governor| object
+containing four callback pointers, :c:member:`enable`, :c:member:`disable`,
+:c:member:`select`, :c:member:`reflect`, a :c:member:`rating` field described
+below, and a name (string) used for identifying it.
+
+For the governor to be available at all, that object needs to be registered
+with the ``CPUIdle`` core by calling :c:func:`cpuidle_register_governor()` with
+a pointer to it passed as the argument. If successful, that causes the core to
+add the governor to the global list of available governors and, if it is the
+only one in the list (that is, the list was empty before) or the value of its
+:c:member:`rating` field is greater than the value of that field for the
+governor currently in use, or the name of the new governor was passed to the
+kernel as the value of the ``cpuidle.governor=`` command line parameter, the new
+governor will be used from that point on (there can be only one ``CPUIdle``
+governor in use at a time). Also, if ``cpuidle_sysfs_switch`` is passed to the
+kernel in the command line, user space can choose the ``CPUIdle`` governor to
+use at run time via ``sysfs``.
+
+Once registered, ``CPUIdle`` governors cannot be unregistered, so it is not
+practical to put them into loadable kernel modules.
+
+The interface between ``CPUIdle`` governors and the core consists of four
+callbacks:
+
+:c:member:`enable`
+ ::
+
+ int (*enable) (struct cpuidle_driver *drv, struct cpuidle_device *dev);
+
+ The role of this callback is to prepare the governor for handling the
+ (logical) CPU represented by the |struct cpuidle_device| object pointed
+ to by the ``dev`` argument. The |struct cpuidle_driver| object pointed
+ to by the ``drv`` argument represents the ``CPUIdle`` driver to be used
+ with that CPU (among other things, it should contain the list of
+ |struct cpuidle_state| objects representing idle states that the
+ processor holding the given CPU can be asked to enter).
+
+ It may fail, in which case it is expected to return a negative error
+ code, and that causes the kernel to run the architecture-specific
+ default code for idle CPUs on the CPU in question instead of ``CPUIdle``
+ until the ``->enable()`` governor callback is invoked for that CPU
+ again.
+
+:c:member:`disable`
+ ::
+
+ void (*disable) (struct cpuidle_driver *drv, struct cpuidle_device *dev);
+
+ Called to make the governor stop handling the (logical) CPU represented
+ by the |struct cpuidle_device| object pointed to by the ``dev``
+ argument.
+
+ It is expected to reverse any changes made by the ``->enable()``
+ callback when it was last invoked for the target CPU, free all memory
+ allocated by that callback and so on.
+
+:c:member:`select`
+ ::
+
+ int (*select) (struct cpuidle_driver *drv, struct cpuidle_device *dev,
+ bool *stop_tick);
+
+ Called to select an idle state for the processor holding the (logical)
+ CPU represented by the |struct cpuidle_device| object pointed to by the
+ ``dev`` argument.
+
+ The list of idle states to take into consideration is represented by the
+ :c:member:`states` array of |struct cpuidle_state| objects held by the
+ |struct cpuidle_driver| object pointed to by the ``drv`` argument (which
+ represents the ``CPUIdle`` driver to be used with the CPU at hand). The
+ value returned by this callback is interpreted as an index into that
+ array (unless it is a negative error code).
+
+ The ``stop_tick`` argument is used to indicate whether or not to stop
+ the scheduler tick before asking the processor to enter the selected
+ idle state. When the ``bool`` variable pointed to by it (which is set
+ to ``true`` before invoking this callback) is cleared to ``false``, the
+ processor will be asked to enter the selected idle state without
+ stopping the scheduler tick on the given CPU (if the tick has been
+ stopped on that CPU already, however, it will not be restarted before
+ asking the processor to enter the idle state).
+
+ This callback is mandatory (i.e. the :c:member:`select` callback pointer
+ in |struct cpuidle_governor| must not be ``NULL`` for the registration
+ of the governor to succeed).
+
+:c:member:`reflect`
+ ::
+
+ void (*reflect) (struct cpuidle_device *dev, int index);
+
+ Called to allow the governor to evaluate the accuracy of the idle state
+ selection made by the ``->select()`` callback (when it was invoked last
+ time) and possibly use the result of that to improve the accuracy of
+ idle state selections in the future.
+
+In addition, ``CPUIdle`` governors are required to take power management
+quality of service (PM QoS) constraints on the processor wakeup latency into
+account when selecting idle states. In order to obtain the current effective
+PM QoS wakeup latency constraint for a given CPU, a ``CPUIdle`` governor is
+expected to pass the number of the CPU to
+:c:func:`cpuidle_governor_latency_req()`. Then, the governor's ``->select()``
+callback must not return the index of an indle state whose
+:c:member:`exit_latency` value is greater than the number returned by that
+function.
+
+
+CPU Idle Time Management Drivers
+================================
+
+CPU idle time management (``CPUIdle``) drivers provide an interface between the
+other parts of ``CPUIdle`` and the hardware.
+
+First of all, a ``CPUIdle`` driver has to populate the :c:member:`states` array
+of |struct cpuidle_state| objects included in the |struct cpuidle_driver| object
+representing it. Going forward this array will represent the list of available
+idle states that the processor hardware can be asked to enter shared by all of
+the logical CPUs handled by the given driver.
+
+The entries in the :c:member:`states` array are expected to be sorted by the
+value of the :c:member:`target_residency` field in |struct cpuidle_state| in
+the ascending order (that is, index 0 should correspond to the idle state with
+the minimum value of :c:member:`target_residency`). [Since the
+:c:member:`target_residency` value is expected to reflect the "depth" of the
+idle state represented by the |struct cpuidle_state| object holding it, this
+sorting order should be the same as the ascending sorting order by the idle
+state "depth".]
+
+Three fields in |struct cpuidle_state| are used by the existing ``CPUIdle``
+governors for computations related to idle state selection:
+
+:c:member:`target_residency`
+ Minimum time to spend in this idle state including the time needed to
+ enter it (which may be substantial) to save more energy than could
+ be saved by staying in a shallower idle state for the same amount of
+ time, in microseconds.
+
+:c:member:`exit_latency`
+ Maximum time it will take a CPU asking the processor to enter this idle
+ state to start executing the first instruction after a wakeup from it,
+ in microseconds.
+
+:c:member:`flags`
+ Flags representing idle state properties. Currently, governors only use
+ the ``CPUIDLE_FLAG_POLLING`` flag which is set if the given object
+ does not represent a real idle state, but an interface to a software
+ "loop" that can be used in order to avoid asking the processor to enter
+ any idle state at all. [There are other flags used by the ``CPUIdle``
+ core in special situations.]
+
+The :c:member:`enter` callback pointer in |struct cpuidle_state|, which must not
+be ``NULL``, points to the routine to execute in order to ask the processor to
+enter this particular idle state:
+
+::
+
+ void (*enter) (struct cpuidle_device *dev, struct cpuidle_driver *drv,
+ int index);
+
+The first two arguments of it point to the |struct cpuidle_device| object
+representing the logical CPU running this callback and the
+|struct cpuidle_driver| object representing the driver itself, respectively,
+and the last one is an index of the |struct cpuidle_state| entry in the driver's
+:c:member:`states` array representing the idle state to ask the processor to
+enter.
+
+The analogous ``->enter_s2idle()`` callback in |struct cpuidle_state| is used
+only for implementing the suspend-to-idle system-wide power management feature.
+The difference between in and ``->enter()`` is that it must not re-enable
+interrupts at any point (even temporarily) or attempt to change the states of
+clock event devices, which the ``->enter()`` callback may do sometimes.
+
+Once the :c:member:`states` array has been populated, the number of valid
+entries in it has to be stored in the :c:member:`state_count` field of the
+|struct cpuidle_driver| object representing the driver. Moreover, if any
+entries in the :c:member:`states` array represent "coupled" idle states (that
+is, idle states that can only be asked for if multiple related logical CPUs are
+idle), the :c:member:`safe_state_index` field in |struct cpuidle_driver| needs
+to be the index of an idle state that is not "coupled" (that is, one that can be
+asked for if only one logical CPU is idle).
+
+In addition to that, if the given ``CPUIdle`` driver is only going to handle a
+subset of logical CPUs in the system, the :c:member:`cpumask` field in its
+|struct cpuidle_driver| object must point to the set (mask) of CPUs that will be
+handled by it.
+
+A ``CPUIdle`` driver can only be used after it has been registered. If there
+are no "coupled" idle state entries in the driver's :c:member:`states` array,
+that can be accomplished by passing the driver's |struct cpuidle_driver| object
+to :c:func:`cpuidle_register_driver()`. Otherwise, :c:func:`cpuidle_register()`
+should be used for this purpose.
+
+However, it also is necessary to register |struct cpuidle_device| objects for
+all of the logical CPUs to be handled by the given ``CPUIdle`` driver with the
+help of :c:func:`cpuidle_register_device()` after the driver has been registered
+and :c:func:`cpuidle_register_driver()`, unlike :c:func:`cpuidle_register()`,
+does not do that automatically. For this reason, the drivers that use
+:c:func:`cpuidle_register_driver()` to register themselves must also take care
+of registering the |struct cpuidle_device| objects as needed, so it is generally
+recommended to use :c:func:`cpuidle_register()` for ``CPUIdle`` driver
+registration in all cases.
+
+The registration of a |struct cpuidle_device| object causes the ``CPUIdle``
+``sysfs`` interface to be created and the governor's ``->enable()`` callback to
+be invoked for the logical CPU represented by it, so it must take place after
+registering the driver that will handle the CPU in question.
+
+``CPUIdle`` drivers and |struct cpuidle_device| objects can be unregistered
+when they are not necessary any more which allows some resources associated with
+them to be released. Due to dependencies between them, all of the
+|struct cpuidle_device| objects representing CPUs handled by the given
+``CPUIdle`` driver must be unregistered, with the help of
+:c:func:`cpuidle_unregister_device()`, before calling
+:c:func:`cpuidle_unregister_driver()` to unregister the driver. Alternatively,
+:c:func:`cpuidle_unregister()` can be called to unregister a ``CPUIdle`` driver
+along with all of the |struct cpuidle_device| objects representing CPUs handled
+by it.
+
+``CPUIdle`` drivers can respond to runtime system configuration changes that
+lead to modifications of the list of available processor idle states (which can
+happen, for example, when the system's power source is switched from AC to
+battery or the other way around). Upon a notification of such a change,
+a ``CPUIdle`` driver is expected to call :c:func:`cpuidle_pause_and_lock()` to
+turn ``CPUIdle`` off temporarily and then :c:func:`cpuidle_disable_device()` for
+all of the |struct cpuidle_device| objects representing CPUs affected by that
+change. Next, it can update its :c:member:`states` array in accordance with
+the new configuration of the system, call :c:func:`cpuidle_enable_device()` for
+all of the relevant |struct cpuidle_device| objects and invoke
+:c:func:`cpuidle_resume_and_unlock()` to allow ``CPUIdle`` to be used again.

+
+The Android binderfs Filesystem
+===============================
+
+Android binderfs is a filesystem for the Android binder IPC mechanism. It
+allows to dynamically add and remove binder devices at runtime. Binder devices
+located in a new binderfs instance are independent of binder devices located in
+other binderfs instances. Mounting a new binderfs instance makes it possible
+to get a set of private binder devices.
+
+Mounting binderfs
+-----------------
+
+Android binderfs can be mounted with::
+
+ mkdir /dev/binderfs
+ mount -t binder binder /dev/binderfs
+
+at which point a new instance of binderfs will show up at ``/dev/binderfs``.
+In a fresh instance of binderfs no binder devices will be present. There will
+only be a ``binder-control`` device which serves as the request handler for
+binderfs. Mounting another binderfs instance at a different location will
+create a new and separate instance from all other binderfs mounts. This is
+identical to the behavior of e.g. ``devpts`` and ``tmpfs``. The Android
+binderfs filesystem can be mounted in user namespaces.
+
+Options
+-------
+max
+ binderfs instances can be mounted with a limit on the number of binder
+ devices that can be allocated. The ``max=<count>`` mount option serves as
+ a per-instance limit. If ``max=<count>`` is set then only ``<count>`` number
+ of binder devices can be allocated in this binderfs instance.
+
+Allocating binder Devices
+-------------------------
+
+.. _ioctl: http://man7.org/linux/man-pages/man2/ioctl.2.html
+
+To allocate a new binder device in a binderfs instance a request needs to be
+sent through the ``binder-control`` device node. A request is sent in the form
+of an `ioctl() <ioctl_>`_.
+
+What a program needs to do is to open the ``binder-control`` device node and
+send a ``BINDER_CTL_ADD`` request to the kernel. Users of binderfs need to
+tell the kernel which name the new binder device should get. By default a name
+can only contain up to ``BINDERFS_MAX_NAME`` chars including the terminating
+zero byte.
+
+Once the request is made via an `ioctl() <ioctl_>`_ passing a ``struct
+binder_device`` with the name to the kernel it will allocate a new binder
+device and return the major and minor number of the new device in the struct
+(This is necessary because binderfs allocates a major device number
+dynamically.). After the `ioctl() <ioctl_>`_ returns there will be a new
+binder device located under /dev/binderfs with the chosen name.
+
+Deleting binder Devices
+-----------------------
+
+.. _unlink: http://man7.org/linux/man-pages/man2/unlink.2.html
+.. _rm: http://man7.org/linux/man-pages/man1/rm.1.html
+
+Binderfs binder devices can be deleted via `unlink() <unlink_>`_. This means
+that the `rm() <rm_>`_ tool can be used to delete them. Note that the
+``binder-control`` device cannot be deleted since this would make the binderfs
+instance unuseable. The ``binder-control`` device will be deleted when the
+binderfs instance is unmounted and all references to it have been dropped.

-===============================================================================
-WHAT IS EXOFS?
-===============================================================================
-
-exofs is a file system that uses an OSD and exports the API of a normal Linux
-file system. Users access exofs like any other local file system, and exofs
-will in turn issue commands to the local OSD initiator.
-
-OSD is a new T10 command set that views storage devices not as a large/flat
-array of sectors but as a container of objects, each having a length, quota,
-time attributes and more. Each object is addressed by a 64bit ID, and is
-contained in a 64bit ID partition. Each object has associated attributes
-attached to it, which are integral part of the object and provide metadata about
-the object. The standard defines some common obligatory attributes, but user
-attributes can be added as needed.
-
-===============================================================================
-ENVIRONMENT
-===============================================================================
-
-To use this file system, you need to have an object store to run it on. You
-may download a target from:
-http://open-osd.org
-
-See Documentation/scsi/osd.txt for how to setup a working osd environment.
-
-===============================================================================
-USAGE
-===============================================================================
-
-1. Download and compile exofs and open-osd initiator:
- You need an external Kernel source tree or kernel headers from your
- distribution. (anything based on 2.6.26 or later).
-
- a. download open-osd including exofs source using:
- [parent-directory]$ git clone git://git.open-osd.org/open-osd.git
-
- b. Build the library module like this:
- [parent-directory]$ make -C KSRC=$(KER_DIR) open-osd
-
- This will build both the open-osd initiator as well as the exofs kernel
- module. Use whatever parameters you compiled your Kernel with and
- $(KER_DIR) above pointing to the Kernel you compile against. See the file
- open-osd/top-level-Makefile for an example.
-
-2. Get the OSD initiator and target set up properly, and login to the target.
- See Documentation/scsi/osd.txt for farther instructions. Also see ./do-osd
- for example script that does all these steps.
-
-3. Insmod the exofs.ko module:
- [exofs]$ insmod exofs.ko
-
-4. Make sure the directory where you want to mount exists. If not, create it.
- (For example, mkdir /mnt/exofs)
-
-5. At first run you will need to invoke the mkfs.exofs application
-
- As an example, this will create the file system on:
- /dev/osd0 partition ID 65536
-
- mkfs.exofs --pid=65536 --format /dev/osd0
-
- The --format is optional. If not specified, no OSD_FORMAT will be
- performed and a clean file system will be created in the specified pid,
- in the available space of the target. (Use --format=size_in_meg to limit
- the total LUN space available)
-
- If pid already exists, it will be deleted and a new one will be created in
- its place. Be careful.
-
- An exofs lives inside a single OSD partition. You can create multiple exofs
- filesystems on the same device using multiple pids.
-
- (run mkfs.exofs without any parameters for usage help message)
-
-6. Mount the file system.
-
- For example, to mount /dev/osd0, partition ID 0x10000 on /mnt/exofs:
-
- mount -t exofs -o pid=65536 /dev/osd0 /mnt/exofs/
-
-7. For reference (See do-exofs example script):
- do-exofs start - an example of how to perform the above steps.
- do-exofs stop - an example of how to unmount the file system.
- do-exofs format - an example of how to format and mkfs a new exofs.
-
-8. Extra compilation flags (uncomment in fs/exofs/Kbuild):
- CONFIG_EXOFS_DEBUG - for debug messages and extra checks.
-
-===============================================================================
-exofs mount options
-===============================================================================
-Similar to any mount command:
- mount -t exofs -o exofs_options /dev/osdX mount_exofs_directory
-
-Where:
- -t exofs: specifies the exofs file system
-
- /dev/osdX: X is a decimal number. /dev/osdX was created after a successful
- login into an OSD target.
-
- mount_exofs_directory: The directory to mount the file system on
-
- exofs specific options: Options are separated by commas (,)
- pid=<integer> - The partition number to mount/create as
- container of the filesystem.
- This option is mandatory. integer can be
- Hex by pre-pending an 0x to the number.
- osdname=<id> - Mount by a device's osdname.
- osdname is usually a 36 character uuid of the
- form "d2683732-c906-4ee1-9dbd-c10c27bb40df".
- It is one of the device's uuid specified in the
- mkfs.exofs format command.
- If this option is specified then the /dev/osdX
- above can be empty and is ignored.
- to=<integer> - Timeout in ticks for a single command.
- default is (60 * HZ) [for debugging only]
-
-===============================================================================
-DESIGN
-===============================================================================
-
-* The file system control block (AKA on-disk superblock) resides in an object
- with a special ID (defined in common.h).
- Information included in the file system control block is used to fill the
- in-memory superblock structure at mount time. This object is created before
- the file system is used by mkexofs.c. It contains information such as:
- - The file system's magic number
- - The next inode number to be allocated
-
-* Each file resides in its own object and contains the data (and it will be
- possible to extend the file over multiple objects, though this has not been
- implemented yet).
-
-* A directory is treated as a file, and essentially contains a list of <file
- name, inode #> pairs for files that are found in that directory. The object
- IDs correspond to the files' inode numbers and will be allocated according to
- a bitmap (stored in a separate object). Now they are allocated using a
- counter.
-
-* Each file's control block (AKA on-disk inode) is stored in its object's
- attributes. This applies to both regular files and other types (directories,
- device files, symlinks, etc.).
-
-* Credentials are generated per object (inode and superblock) when they are
- created in memory (read from disk or created). The credential works for all
- operations and is used as long as the object remains in memory.
-
-* Async OSD operations are used whenever possible, but the target may execute
- them out of order. The operations that concern us are create, delete,
- readpage, writepage, update_inode, and truncate. The following pairs of
- operations should execute in the order written, and we need to prevent them
- from executing in reverse order:
- - The following are handled with the OBJ_CREATED and OBJ_2BCREATED
- flags. OBJ_CREATED is set when we know the object exists on the OSD -
- in create's callback function, and when we successfully do a
- read_inode.
- OBJ_2BCREATED is set in the beginning of the create function, so we
- know that we should wait.
- - create/delete: delete should wait until the object is created
- on the OSD.
- - create/readpage: readpage should be able to return a page
- full of zeroes in this case. If there was a write already
- en-route (i.e. create, writepage, readpage) then the page
- would be locked, and so it would really be the same as
- create/writepage.
- - create/writepage: if writepage is called for a sync write, it
- should wait until the object is created on the OSD.
- Otherwise, it should just return.
- - create/truncate: truncate should wait until the object is
- created on the OSD.
- - create/update_inode: update_inode should wait until the
- object is created on the OSD.
- - Handled by VFS locks:
- - readpage/delete: shouldn't happen because of page lock.
- - writepage/delete: shouldn't happen because of page lock.
- - readpage/writepage: shouldn't happen because of page lock.

Per-file keys
-------------
-Master keys are not used to encrypt file contents or names directly.
-Instead, a unique key is derived for each encrypted file, including
-each regular file, directory, and symbolic link. This has several
-advantages:
-
-- In cryptosystems, the same key material should never be used for
- different purposes. Using the master key as both an XTS key for
- contents encryption and as a CTS-CBC key for filenames encryption
- would violate this rule.
-- Per-file keys simplify the choice of IVs (Initialization Vectors)
- for contents encryption. Without per-file keys, to ensure IV
- uniqueness both the inode and logical block number would need to be
- encoded in the IVs. This would make it impossible to renumber
- inodes, which e.g. ``resize2fs`` can do when resizing an ext4
- filesystem. With per-file keys, it is sufficient to encode just the
- logical block number in the IVs.
-- Per-file keys strengthen the encryption of filenames, where IVs are
- reused out of necessity. With a unique key per directory, IV reuse
- is limited to within a single directory.
-- Per-file keys allow individual files to be securely erased simply by
- securely erasing their keys. (Not yet implemented.)
-
-A KDF (Key Derivation Function) is used to derive per-file keys from
-the master key. This is done instead of wrapping a randomly-generated
-key for each file because it reduces the size of the encryption xattr,
-which for some filesystems makes the xattr more likely to fit in-line
-in the filesystem's inode table. With a KDF, only a 16-byte nonce is
-required --- long enough to make key reuse extremely unlikely. A
-wrapped key, on the other hand, would need to be up to 64 bytes ---
-the length of an AES-256-XTS key. Furthermore, currently there is no
-requirement to support unlocking a file with multiple alternative
-master keys or to support rotating master keys. Instead, the master
-keys may be wrapped in userspace, e.g. as done by the `fscrypt
-<https://github.com/google/fscrypt>`_ tool.
-
-The current KDF encrypts the master key using the 16-byte nonce as an
-AES-128-ECB key. The output is used as the derived key. If the
-output is longer than needed, then it is truncated to the needed
-length. Truncation is the norm for directories and symlinks, since
-those use the CTS-CBC encryption mode which requires a key half as
-long as that required by the XTS encryption mode.
+Since each master key can protect many files, it is necessary to
+"tweak" the encryption of each file so that the same plaintext in two
+files doesn't map to the same ciphertext, or vice versa. In most
+cases, fscrypt does this by deriving per-file keys. When a new
+encrypted inode (regular file, directory, or symlink) is created,
+fscrypt randomly generates a 16-byte nonce and stores it in the
+inode's encryption xattr. Then, it uses a KDF (Key Derivation
+Function) to derive the file's key from the master key and nonce.
+
+The Adiantum encryption mode (see `Encryption modes and usage`_) is
+special, since it accepts longer IVs and is suitable for both contents
+and filenames encryption. For it, a "direct key" option is offered
+where the file's nonce is included in the IVs and the master key is

+users must not use the same master key for any other encryption mode.
+
+Below, the KDF and design considerations are described in more detail.
+

Encryption modes and usage
==========================
@@ -191,54 +186,80 @@ Currently, the following pairs of encryption modes are supported:
- AES-256-XTS for contents and AES-256-CTS-CBC for filenames
- AES-128-CBC for contents and AES-128-CTS-CBC for filenames

+
+If unsure, you should use the (AES-256-XTS, AES-256-CTS-CBC) pair.
-It is strongly recommended to use AES-256-XTS for contents encryption.
AES-128-CBC was added only for low-powered embedded devices with
crypto accelerators such as CAAM or CESA that do not support XTS.
+Adiantum is a (primarily) stream cipher-based mode that is fast even
+on CPUs without dedicated crypto instructions. It's also a true
+wide-block mode, unlike XTS. It can also eliminate the need to derive
+per-file keys. However, it depends on the security of two primitives,
+XChaCha12 and AES-256, rather than just one. See the paper
+"Adiantum: length-preserving encryption for entry-level processors"
+(https://eprint.iacr.org/2018/720.pdf) for more details. To use
+Adiantum, CONFIG_CRYPTO_ADIANTUM must be enabled. Also, fast
+implementations of ChaCha and NHPoly1305 should be enabled, e.g.
+CONFIG_CRYPTO_CHACHA20_NEON and CONFIG_CRYPTO_NHPOLY1305_NEON for ARM.
+
New encryption modes can be added relatively easily, without changes
to individual filesystems. However, authenticated encryption (AE)
modes are not currently supported because of the difficulty of dealing
with ciphertext expansion.
+Contents encryption
+-------------------
+
For file contents, each filesystem block is encrypted independently.
Currently, only the case where the filesystem block size is equal to
-the system's page size (usually 4096 bytes) is supported. With the
-XTS mode of operation (recommended), the logical block number within
-the file is used as the IV. With the CBC mode of operation (not
-recommended), ESSIV is used; specifically, the IV for CBC is the
-logical block number encrypted with AES-256, where the AES-256 key is
-the SHA-256 hash of the inode's data encryption key.
-
-For filenames, the full filename is encrypted at once. Because of the
-requirements to retain support for efficient directory lookups and
-filenames of up to 255 bytes, a constant initialization vector (IV) is
-used. However, each encrypted directory uses a unique key, which
-limits IV reuse to within a single directory. Note that IV reuse in
-the context of CTS-CBC encryption means that when the original
-filenames share a common prefix at least as long as the cipher block
-size (16 bytes for AES), the corresponding encrypted filenames will
-also share a common prefix. This is undesirable; it may be fixed in
-the future by switching to an encryption mode that is a strong
-pseudorandom permutation on arbitrary-length messages, e.g. the HEH
-(Hash-Encrypt-Hash) mode.
-
-Since filenames are encrypted with the CTS-CBC mode of operation, the
-plaintext and ciphertext filenames need not be multiples of the AES
-block size, i.e. 16 bytes. However, the minimum size that can be
-encrypted is 16 bytes, so shorter filenames are NUL-padded to 16 bytes
-before being encrypted. In addition, to reduce leakage of filename
-lengths via their ciphertexts, all filenames are NUL-padded to the
-next 4, 8, 16, or 32-byte boundary (configurable). 32 is recommended
-since this provides the best confidentiality, at the cost of making
-directory entries consume slightly more space. Note that since NUL
-(``\0``) is not otherwise a valid character in filenames, the padding
-will never produce duplicate plaintexts.

+
+- In the "direct key" configuration (FS_POLICY_FLAG_DIRECT_KEY set in

+
+Filenames encryption
+--------------------
+
+For filenames, each full filename is encrypted at once. Because of
+the requirements to retain support for efficient directory lookups and
+filenames of up to 255 bytes, the same IV is used for every filename
+in a directory.
+
+However, each encrypted directory still uses a unique key; or
+alternatively (for the "direct key" configuration) has the file's
+nonce included in the IVs. Thus, IV reuse is limited to within a
+single directory.
+
+With CTS-CBC, the IV reuse means that when the plaintext filenames
+share a common prefix at least as long as the cipher block size (16
+bytes for AES), the corresponding encrypted filenames will also share
+a common prefix. This is undesirable. Adiantum does not have this
+weakness, as it is a wide-block encryption mode.
+
+All supported filenames encryption modes accept any plaintext length
+>= 16 bytes; cipher block alignment is not required. However,
+filenames shorter than 16 bytes are NUL-padded to 16 bytes before
+being encrypted. In addition, to reduce leakage of filename lengths

-The Linux Journalling API
+Filesystem support layers
=========================
-Overview
---------
-
-Details
-~~~~~~~
-
-The journalling layer is easy to use. You need to first of all create a
-journal_t data structure. There are two calls to do this dependent on
-how you decide to allocate the physical media on which the journal
-resides. The :c:func:`jbd2_journal_init_inode` call is for journals stored in
-filesystem inodes, or the :c:func:`jbd2_journal_init_dev` call can be used
-for journal stored on a raw device (in a continuous range of blocks). A
-journal_t is a typedef for a struct pointer, so when you are finally
-finished make sure you call :c:func:`jbd2_journal_destroy` on it to free up
-any used kernel memory.
-
-Once you have got your journal_t object you need to 'mount' or load the
-journal file. The journalling layer expects the space for the journal
-was already allocated and initialized properly by the userspace tools.
-When loading the journal you must call :c:func:`jbd2_journal_load` to process
-journal contents. If the client file system detects the journal contents
-does not need to be processed (or even need not have valid contents), it
-may call :c:func:`jbd2_journal_wipe` to clear the journal contents before
-calling :c:func:`jbd2_journal_load`.
-
-Note that jbd2_journal_wipe(..,0) calls
-:c:func:`jbd2_journal_skip_recovery` for you if it detects any outstanding
-transactions in the journal and similarly :c:func:`jbd2_journal_load` will
-call :c:func:`jbd2_journal_recover` if necessary. I would advise reading
-:c:func:`ext4_load_journal` in fs/ext4/super.c for examples on this stage.
-
-Now you can go ahead and start modifying the underlying filesystem.
-Almost.
-
-You still need to actually journal your filesystem changes, this is done
-by wrapping them into transactions. Additionally you also need to wrap
-the modification of each of the buffers with calls to the journal layer,
-so it knows what the modifications you are actually making are. To do
-this use :c:func:`jbd2_journal_start` which returns a transaction handle.
-
-:c:func:`jbd2_journal_start` and its counterpart :c:func:`jbd2_journal_stop`,
-which indicates the end of a transaction are nestable calls, so you can
-reenter a transaction if necessary, but remember you must call
-:c:func:`jbd2_journal_stop` the same number of times as
-:c:func:`jbd2_journal_start` before the transaction is completed (or more
-accurately leaves the update phase). Ext4/VFS makes use of this feature to
-simplify handling of inode dirtying, quota support, etc.
-
-Inside each transaction you need to wrap the modifications to the
-individual buffers (blocks). Before you start to modify a buffer you
-need to call :c:func:`jbd2_journal_get_create_access()` /
-:c:func:`jbd2_journal_get_write_access()` /
-:c:func:`jbd2_journal_get_undo_access()` as appropriate, this allows the
-journalling layer to copy the unmodified
-data if it needs to. After all the buffer may be part of a previously
-uncommitted transaction. At this point you are at last ready to modify a
-buffer, and once you are have done so you need to call
-:c:func:`jbd2_journal_dirty_metadata`. Or if you've asked for access to a
-buffer you now know is now longer required to be pushed back on the
-device you can call :c:func:`jbd2_journal_forget` in much the same way as you
-might have used :c:func:`bforget` in the past.
-
-A :c:func:`jbd2_journal_flush` may be called at any time to commit and
-checkpoint all your transactions.
-
-Then at umount time , in your :c:func:`put_super` you can then call
-:c:func:`jbd2_journal_destroy` to clean up your in-core journal object.
-
-Unfortunately there a couple of ways the journal layer can cause a
-deadlock. The first thing to note is that each task can only have a
-single outstanding transaction at any one time, remember nothing commits
-until the outermost :c:func:`jbd2_journal_stop`. This means you must complete
-the transaction at the end of each file/inode/address etc. operation you
-perform, so that the journalling system isn't re-entered on another
-journal. Since transactions can't be nested/batched across differing
-journals, and another filesystem other than yours (say ext4) may be
-modified in a later syscall.
-
-The second case to bear in mind is that :c:func:`jbd2_journal_start` can block
-if there isn't enough space in the journal for your transaction (based
-on the passed nblocks param) - when it blocks it merely(!) needs to wait
-for transactions to complete and be committed from other tasks, so
-essentially we are waiting for :c:func:`jbd2_journal_stop`. So to avoid
-deadlocks you must treat :c:func:`jbd2_journal_start` /
-:c:func:`jbd2_journal_stop` as if they were semaphores and include them in
-your semaphore ordering rules to prevent
-deadlocks. Note that :c:func:`jbd2_journal_extend` has similar blocking
-behaviour to :c:func:`jbd2_journal_start` so you can deadlock here just as
-easily as on :c:func:`jbd2_journal_start`.
-
-Try to reserve the right number of blocks the first time. ;-). This will
-be the maximum number of blocks you are going to touch in this
-transaction. I advise having a look at at least ext4_jbd.h to see the
-basis on which ext4 uses to make these decisions.
-
-Another wriggle to watch out for is your on-disk block allocation
-strategy. Why? Because, if you do a delete, you need to ensure you
-haven't reused any of the freed blocks until the transaction freeing
-these blocks commits. If you reused these blocks and crash happens,
-there is no way to restore the contents of the reallocated blocks at the
-end of the last fully committed transaction. One simple way of doing
-this is to mark blocks as free in internal in-memory block allocation
-structures only after the transaction freeing them commits. Ext4 uses
-journal commit callback for this purpose.
-
-With journal commit callbacks you can ask the journalling layer to call
-a callback function when the transaction is finally committed to disk,
-so that you can do some of your own management. You ask the journalling
-layer for calling the callback by simply setting
-``journal->j_commit_callback`` function pointer and that function is
-called after each transaction commit. You can also use
-``transaction->t_private_list`` for attaching entries to a transaction
-that need processing when the transaction commits.
-
-JBD2 also provides a way to block all transaction updates via
-:c:func:`jbd2_journal_lock_updates()` /
-:c:func:`jbd2_journal_unlock_updates()`. Ext4 uses this when it wants a
-window with a clean and stable fs for a moment. E.g.
-
-::
-
-
- jbd2_journal_lock_updates() //stop new stuff happening..
- jbd2_journal_flush() // checkpoint everything.
- ..do stuff on stable fs
- jbd2_journal_unlock_updates() // carry on with filesystem use.
-
-The opportunities for abuse and DOS attacks with this should be obvious,
-if you allow unprivileged userspace to trigger codepaths containing
-these calls.

-Summary
-~~~~~~~
+Documentation for the support code within the filesystem layer for use in
+filesystem implementations.
-Using the journal is a matter of wrapping the different context changes,
-being each mount, each modification (transaction) and each changed
-buffer to tell the journalling layer about them.
-
-Data Types
-----------
-
-The journalling layer uses typedefs to 'hide' the concrete definitions
-of the structures used. As a client of the JBD2 layer you can just rely
-on the using the pointer as a magic cookie of some sort. Obviously the

+========
+OVERVIEW
+========
+
+The creation of new mounts is now to be done in a multistep process:
+
+ (1) Create a filesystem context.
+
+ (2) Parse the parameters and attach them to the context. Parameters are
+ expected to be passed individually from userspace, though legacy binary
+ parameters can also be handled.
+
+ (3) Validate and pre-process the context.
+
+ (4) Get or create a superblock and mountable root.
+
+ (5) Perform the mount.
+
+ (6) Return an error message attached to the context.
+
+ (7) Destroy the context.
+
+To support this, the file_system_type struct gains two new fields:
+
+ int (*init_fs_context)(struct fs_context *fc);
+ const struct fs_parameter_description *parameters;
+
+The first is invoked to set up the filesystem-specific parts of a filesystem
+context, including the additional space, and the second points to the
+parameter description for validation at registration time and querying by a
+future system call.
+
+Note that security initialisation is done *after* the filesystem is called so
+that the namespaces may be adjusted first.
+
+
+======================
+THE FILESYSTEM CONTEXT
+======================
+
+The creation and reconfiguration of a superblock is governed by a filesystem
+context. This is represented by the fs_context structure:
+
+ struct fs_context {
+ const struct fs_context_operations *ops;
+ struct file_system_type *fs_type;
+ void *fs_private;
+ struct dentry *root;
+ struct user_namespace *user_ns;
+ struct net *net_ns;
+ const struct cred *cred;
+ char *source;
+ char *subtype;
+ void *security;
+ void *s_fs_info;
+ unsigned int sb_flags;
+ unsigned int sb_flags_mask;
+ unsigned int s_iflags;
+ unsigned int lsm_flags;
+ enum fs_context_purpose purpose:8;
+ ...
+ };
+
+The fs_context fields are as follows:
+
+ (*) const struct fs_context_operations *ops
+
+ These are operations that can be done on a filesystem context (see
+ below). This must be set by the ->init_fs_context() file_system_type
+ operation.
+
+ (*) struct file_system_type *fs_type
+
+ A pointer to the file_system_type of the filesystem that is being
+ constructed or reconfigured. This retains a reference on the type owner.
+
+ (*) void *fs_private
+
+ A pointer to the file system's private data. This is where the filesystem
+ will need to store any options it parses.
+
+ (*) struct dentry *root
+
+ A pointer to the root of the mountable tree (and indirectly, the
+ superblock thereof). This is filled in by the ->get_tree() op. If this
+ is set, an active reference on root->d_sb must also be held.
+
+ (*) struct user_namespace *user_ns
+ (*) struct net *net_ns
+
+ There are a subset of the namespaces in use by the invoking process. They
+ retain references on each namespace. The subscribed namespaces may be
+ replaced by the filesystem to reflect other sources, such as the parent
+ mount superblock on an automount.
+
+ (*) const struct cred *cred
+
+ The mounter's credentials. This retains a reference on the credentials.
+
+ (*) char *source
+
+ This specifies the source. It may be a block device (e.g. /dev/sda1) or
+ something more exotic, such as the "host:/path" that NFS desires.
+
+ (*) char *subtype
+
+ This is a string to be added to the type displayed in /proc/mounts to
+ qualify it (used by FUSE). This is available for the filesystem to set if
+ desired.
+
+ (*) void *security
+
+ A place for the LSMs to hang their security data for the superblock. The
+ relevant security operations are described below.
+
+ (*) void *s_fs_info
+
+ The proposed s_fs_info for a new superblock, set in the superblock by
+ sget_fc(). This can be used to distinguish superblocks.
+
+ (*) unsigned int sb_flags
+ (*) unsigned int sb_flags_mask
+
+ Which bits SB_* flags are to be set/cleared in super_block::s_flags.
+
+ (*) unsigned int s_iflags
+
+ These will be bitwise-OR'd with s->s_iflags when a superblock is created.
+
+ (*) enum fs_context_purpose
+
+ This indicates the purpose for which the context is intended. The
+ available values are:
+
+ FS_CONTEXT_FOR_MOUNT, -- New superblock for explicit mount
+ FS_CONTEXT_FOR_SUBMOUNT -- New automatic submount of extant mount
+ FS_CONTEXT_FOR_RECONFIGURE -- Change an existing mount
+
+The mount context is created by calling vfs_new_fs_context() or
+vfs_dup_fs_context() and is destroyed with put_fs_context(). Note that the
+structure is not refcounted.
+
+VFS, security and filesystem mount options are set individually with
+vfs_parse_mount_option(). Options provided by the old mount(2) system call as
+a page of data can be parsed with generic_parse_monolithic().
+
+When mounting, the filesystem is allowed to take data from any of the pointers
+and attach it to the superblock (or whatever), provided it clears the pointer
+in the mount context.
+
+The filesystem is also allowed to allocate resources and pin them with the
+mount context. For instance, NFS might pin the appropriate protocol version
+module.
+
+
+=================================
+THE FILESYSTEM CONTEXT OPERATIONS
+=================================
+
+The filesystem context points to a table of operations:
+
+ struct fs_context_operations {
+ void (*free)(struct fs_context *fc);
+ int (*dup)(struct fs_context *fc, struct fs_context *src_fc);
+ int (*parse_param)(struct fs_context *fc,
+ struct struct fs_parameter *param);
+ int (*parse_monolithic)(struct fs_context *fc, void *data);
+ int (*get_tree)(struct fs_context *fc);
+ int (*reconfigure)(struct fs_context *fc);
+ };
+
+These operations are invoked by the various stages of the mount procedure to
+manage the filesystem context. They are as follows:
+
+ (*) void (*free)(struct fs_context *fc);
+
+ Called to clean up the filesystem-specific part of the filesystem context
+ when the context is destroyed. It should be aware that parts of the
+ context may have been removed and NULL'd out by ->get_tree().
+
+ (*) int (*dup)(struct fs_context *fc, struct fs_context *src_fc);
+
+ Called when a filesystem context has been duplicated to duplicate the
+ filesystem-private data. An error may be returned to indicate failure to
+ do this.
+
+ [!] Note that even if this fails, put_fs_context() will be called
+ immediately thereafter, so ->dup() *must* make the
+ filesystem-private data safe for ->free().
+
+ (*) int (*parse_param)(struct fs_context *fc,
+ struct struct fs_parameter *param);
+
+ Called when a parameter is being added to the filesystem context. param
+ points to the key name and maybe a value object. VFS-specific options
+ will have been weeded out and fc->sb_flags updated in the context.
+ Security options will also have been weeded out and fc->security updated.
+
+ The parameter can be parsed with fs_parse() and fs_lookup_param(). Note
+ that the source(s) are presented as parameters named "source".
+
+ If successful, 0 should be returned or a negative error code otherwise.
+
+ (*) int (*parse_monolithic)(struct fs_context *fc, void *data);
+
+ Called when the mount(2) system call is invoked to pass the entire data
+ page in one go. If this is expected to be just a list of "key[=val]"
+ items separated by commas, then this may be set to NULL.
+
+ The return value is as for ->parse_param().
+
+ If the filesystem (e.g. NFS) needs to examine the data first and then
+ finds it's the standard key-val list then it may pass it off to
+ generic_parse_monolithic().
+
+ (*) int (*get_tree)(struct fs_context *fc);
+
+ Called to get or create the mountable root and superblock, using the
+ information stored in the filesystem context (reconfiguration goes via a
+ different vector). It may detach any resources it desires from the
+ filesystem context and transfer them to the superblock it creates.
+
+ On success it should set fc->root to the mountable root and return 0. In
+ the case of an error, it should return a negative error code.
+
+ The phase on a userspace-driven context will be set to only allow this to
+ be called once on any particular context.
+
+ (*) int (*reconfigure)(struct fs_context *fc);
+
+ Called to effect reconfiguration of a superblock using information stored
+ in the filesystem context. It may detach any resources it desires from
+ the filesystem context and transfer them to the superblock. The
+ superblock can be found from fc->root->d_sb.
+
+ On success it should return 0. In the case of an error, it should return
+ a negative error code.
+
+ [NOTE] reconfigure is intended as a replacement for remount_fs.
+
+
+===========================
+FILESYSTEM CONTEXT SECURITY
+===========================
+
+The filesystem context contains a security pointer that the LSMs can use for
+building up a security context for the superblock to be mounted. There are a
+number of operations used by the new mount code for this purpose:
+
+ (*) int security_fs_context_alloc(struct fs_context *fc,
+ struct dentry *reference);
+
+ Called to initialise fc->security (which is preset to NULL) and allocate
+ any resources needed. It should return 0 on success or a negative error
+ code on failure.
+
+ reference will be non-NULL if the context is being created for superblock
+ reconfiguration (FS_CONTEXT_FOR_RECONFIGURE) in which case it indicates
+ the root dentry of the superblock to be reconfigured. It will also be
+ non-NULL in the case of a submount (FS_CONTEXT_FOR_SUBMOUNT) in which case
+ it indicates the automount point.
+
+ (*) int security_fs_context_dup(struct fs_context *fc,
+ struct fs_context *src_fc);
+
+ Called to initialise fc->security (which is preset to NULL) and allocate
+ any resources needed. The original filesystem context is pointed to by
+ src_fc and may be used for reference. It should return 0 on success or a
+ negative error code on failure.
+
+ (*) void security_fs_context_free(struct fs_context *fc);
+
+ Called to clean up anything attached to fc->security. Note that the
+ contents may have been transferred to a superblock and the pointer cleared
+ during get_tree.
+
+ (*) int security_fs_context_parse_param(struct fs_context *fc,
+ struct fs_parameter *param);
+
+ Called for each mount parameter, including the source. The arguments are
+ as for the ->parse_param() method. It should return 0 to indicate that
+ the parameter should be passed on to the filesystem, 1 to indicate that
+ the parameter should be discarded or an error to indicate that the
+ parameter should be rejected.
+
+ The value pointed to by param may be modified (if a string) or stolen
+ (provided the value pointer is NULL'd out). If it is stolen, 1 must be
+ returned to prevent it being passed to the filesystem.
+
+ (*) int security_fs_context_validate(struct fs_context *fc);
+
+ Called after all the options have been parsed to validate the collection
+ as a whole and to do any necessary allocation so that
+ security_sb_get_tree() and security_sb_reconfigure() are less likely to
+ fail. It should return 0 or a negative error code.
+
+ In the case of reconfiguration, the target superblock will be accessible
+ via fc->root.
+
+ (*) int security_sb_get_tree(struct fs_context *fc);
+
+ Called during the mount procedure to verify that the specified superblock
+ is allowed to be mounted and to transfer the security data there. It
+ should return 0 or a negative error code.
+
+ (*) void security_sb_reconfigure(struct fs_context *fc);
+
+ Called to apply any reconfiguration to an LSM's context. It must not
+ fail. Error checking and resource allocation must be done in advance by
+ the parameter parsing and validation hooks.
+
+ (*) int security_sb_mountpoint(struct fs_context *fc, struct path *mountpoint,
+ unsigned int mnt_flags);
+
+ Called during the mount procedure to verify that the root dentry attached
+ to the context is permitted to be attached to the specified mountpoint.
+ It should return 0 on success or a negative error code on failure.
+
+
+==========================
+VFS FILESYSTEM CONTEXT API
+==========================
+
+There are four operations for creating a filesystem context and one for
+destroying a context:
+
+ (*) struct fs_context *fs_context_for_mount(
+ struct file_system_type *fs_type,
+ unsigned int sb_flags);
+
+ Allocate a filesystem context for the purpose of setting up a new mount,
+ whether that be with a new superblock or sharing an existing one. This
+ sets the superblock flags, initialises the security and calls
+ fs_type->init_fs_context() to initialise the filesystem private data.
+
+ fs_type specifies the filesystem type that will manage the context and
+ sb_flags presets the superblock flags stored therein.
+
+ (*) struct fs_context *fs_context_for_reconfigure(
+ struct dentry *dentry,
+ unsigned int sb_flags,
+ unsigned int sb_flags_mask);
+
+ Allocate a filesystem context for the purpose of reconfiguring an
+ existing superblock. dentry provides a reference to the superblock to be
+ configured. sb_flags and sb_flags_mask indicate which superblock flags
+ need changing and to what.
+
+ (*) struct fs_context *fs_context_for_submount(
+ struct file_system_type *fs_type,
+ struct dentry *reference);
+
+ Allocate a filesystem context for the purpose of creating a new mount for
+ an automount point or other derived superblock. fs_type specifies the
+ filesystem type that will manage the context and the reference dentry
+ supplies the parameters. Namespaces are propagated from the reference
+ dentry's superblock also.
+
+ Note that it's not a requirement that the reference dentry be of the same
+ filesystem type as fs_type.
+
+ (*) struct fs_context *vfs_dup_fs_context(struct fs_context *src_fc);
+
+ Duplicate a filesystem context, copying any options noted and duplicating
+ or additionally referencing any resources held therein. This is available
+ for use where a filesystem has to get a mount within a mount, such as NFS4
+ does by internally mounting the root of the target server and then doing a
+ private pathwalk to the target directory.
+
+ The purpose in the new context is inherited from the old one.
+
+ (*) void put_fs_context(struct fs_context *fc);
+
+ Destroy a filesystem context, releasing any resources it holds. This
+ calls the ->free() operation. This is intended to be called by anyone who
+ created a filesystem context.
+
+ [!] filesystem contexts are not refcounted, so this causes unconditional
+ destruction.
+
+In all the above operations, apart from the put op, the return is a mount
+context pointer or a negative error code.
+
+For the remaining operations, if an error occurs, a negative error code will be
+returned.
+
+ (*) int vfs_parse_fs_param(struct fs_context *fc,
+ struct fs_parameter *param);
+
+ Supply a single mount parameter to the filesystem context. This include
+ the specification of the source/device which is specified as the "source"
+ parameter (which may be specified multiple times if the filesystem
+ supports that).
+
+ param specifies the parameter key name and the value. The parameter is
+ first checked to see if it corresponds to a standard mount flag (in which
+ case it is used to set an SB_xxx flag and consumed) or a security option
+ (in which case the LSM consumes it) before it is passed on to the
+ filesystem.
+
+ The parameter value is typed and can be one of:
+
+ fs_value_is_flag, Parameter not given a value.
+ fs_value_is_string, Value is a string
+ fs_value_is_blob, Value is a binary blob
+ fs_value_is_filename, Value is a filename* + dirfd
+ fs_value_is_filename_empty, Value is a filename* + dirfd + AT_EMPTY_PATH
+ fs_value_is_file, Value is an open file (file*)
+
+ If there is a value, that value is stored in a union in the struct in one
+ of param->{string,blob,name,file}. Note that the function may steal and
+ clear the pointer, but then becomes responsible for disposing of the
+ object.
+
+ (*) int vfs_parse_fs_string(struct fs_context *fc, const char *key,
+ const char *value, size_t v_size);
+
+ A wrapper around vfs_parse_fs_param() that copies the value string it is
+ passed.
+
+ (*) int generic_parse_monolithic(struct fs_context *fc, void *data);
+
+ Parse a sys_mount() data page, assuming the form to be a text list
+ consisting of key[=val] options separated by commas. Each item in the
+ list is passed to vfs_mount_option(). This is the default when the
+ ->parse_monolithic() method is NULL.
+
+ (*) int vfs_get_tree(struct fs_context *fc);
+
+ Get or create the mountable root and superblock, using the parameters in
+ the filesystem context to select/configure the superblock. This invokes
+ the ->get_tree() method.
+
+ (*) struct vfsmount *vfs_create_mount(struct fs_context *fc);
+
+ Create a mount given the parameters in the specified filesystem context.
+ Note that this does not attach the mount to anything.
+
+
+===========================
+SUPERBLOCK CREATION HELPERS
+===========================
+
+A number of VFS helpers are available for use by filesystems for the creation
+or looking up of superblocks.
+
+ (*) struct super_block *
+ sget_fc(struct fs_context *fc,
+ int (*test)(struct super_block *sb, struct fs_context *fc),
+ int (*set)(struct super_block *sb, struct fs_context *fc));
+
+ This is the core routine. If test is non-NULL, it searches for an
+ existing superblock matching the criteria held in the fs_context, using
+ the test function to match them. If no match is found, a new superblock
+ is created and the set function is called to set it up.
+
+ Prior to the set function being called, fc->s_fs_info will be transferred
+ to sb->s_fs_info - and fc->s_fs_info will be cleared if set returns
+ success (ie. 0).
+
+The following helpers all wrap sget_fc():
+
+ (*) int vfs_get_super(struct fs_context *fc,
+ enum vfs_get_super_keying keying,
+ int (*fill_super)(struct super_block *sb,
+ struct fs_context *fc))
+
+ This creates/looks up a deviceless superblock. The keying indicates how
+ many superblocks of this type may exist and in what manner they may be
+ shared:
+
+ (1) vfs_get_single_super
+
+ Only one such superblock may exist in the system. Any further
+ attempt to get a new superblock gets this one (and any parameter
+ differences are ignored).
+
+ (2) vfs_get_keyed_super
+
+ Multiple superblocks of this type may exist and they're keyed on
+ their s_fs_info pointer (for example this may refer to a
+ namespace).
+
+ (3) vfs_get_independent_super
+
+ Multiple independent superblocks of this type may exist. This
+ function never matches an existing one and always creates a new
+ one.
+
+
+=====================
+PARAMETER DESCRIPTION
+=====================
+
+Parameters are described using structures defined in linux/fs_parser.h.
+There's a core description struct that links everything together:
+
+ struct fs_parameter_description {
+ const char name[16];
+ const struct fs_parameter_spec *specs;
+ const struct fs_parameter_enum *enums;
+ };
+
+For example:
+
+ enum {
+ Opt_autocell,
+ Opt_bar,
+ Opt_dyn,
+ Opt_foo,
+ Opt_source,
+ };
+
+ static const struct fs_parameter_description afs_fs_parameters = {
+ .name = "kAFS",
+ .specs = afs_param_specs,
+ .enums = afs_param_enums,
+ };
+
+The members are as follows:
+
+ (1) const char name[16];
+
+ The name to be used in error messages generated by the parse helper
+ functions.
+
+ (2) const struct fs_parameter_specification *specs;
+
+ Table of parameter specifications, terminated with a null entry, where the
+ entries are of type:
+
+ struct fs_parameter_spec {
+ const char *name;
+ u8 opt;
+ enum fs_parameter_type type:8;
+ unsigned short flags;
+ };
+
+ The 'name' field is a string to match exactly to the parameter key (no
+ wildcards, patterns and no case-independence) and 'opt' is the value that
+ will be returned by the fs_parser() function in the case of a successful
+ match.
+
+ The 'type' field indicates the desired value type and must be one of:
+
+ TYPE NAME EXPECTED VALUE RESULT IN
+ ======================= ======================= =====================
+ fs_param_is_flag No value n/a
+ fs_param_is_bool Boolean value result->boolean
+ fs_param_is_u32 32-bit unsigned int result->uint_32
+ fs_param_is_u32_octal 32-bit octal int result->uint_32
+ fs_param_is_u32_hex 32-bit hex int result->uint_32
+ fs_param_is_s32 32-bit signed int result->int_32
+ fs_param_is_u64 64-bit unsigned int result->uint_64
+ fs_param_is_enum Enum value name result->uint_32
+ fs_param_is_string Arbitrary string param->string
+ fs_param_is_blob Binary blob param->blob
+ fs_param_is_blockdev Blockdev path * Needs lookup
+ fs_param_is_path Path * Needs lookup
+ fs_param_is_fd File descriptor result->int_32
+
+ Note that if the value is of fs_param_is_bool type, fs_parse() will try
+ to match any string value against "0", "1", "no", "yes", "false", "true".
+
+ Each parameter can also be qualified with 'flags':
+
+ fs_param_v_optional The value is optional
+ fs_param_neg_with_no result->negated set if key is prefixed with "no"
+ fs_param_neg_with_empty result->negated set if value is ""
+ fs_param_deprecated The parameter is deprecated.
+
+ These are wrapped with a number of convenience wrappers:
+
+ MACRO SPECIFIES
+ ======================= ===============================================
+ fsparam_flag() fs_param_is_flag
+ fsparam_flag_no() fs_param_is_flag, fs_param_neg_with_no
+ fsparam_bool() fs_param_is_bool
+ fsparam_u32() fs_param_is_u32
+ fsparam_u32oct() fs_param_is_u32_octal
+ fsparam_u32hex() fs_param_is_u32_hex
+ fsparam_s32() fs_param_is_s32
+ fsparam_u64() fs_param_is_u64
+ fsparam_enum() fs_param_is_enum
+ fsparam_string() fs_param_is_string
+ fsparam_blob() fs_param_is_blob
+ fsparam_bdev() fs_param_is_blockdev
+ fsparam_path() fs_param_is_path
+ fsparam_fd() fs_param_is_fd
+
+ all of which take two arguments, name string and option number - for
+ example:
+
+ static const struct fs_parameter_spec afs_param_specs[] = {
+ fsparam_flag ("autocell", Opt_autocell),
+ fsparam_flag ("dyn", Opt_dyn),
+ fsparam_string ("source", Opt_source),
+ fsparam_flag_no ("foo", Opt_foo),
+ {}
+ };
+
+ An addition macro, __fsparam() is provided that takes an additional pair
+ of arguments to specify the type and the flags for anything that doesn't
+ match one of the above macros.
+
+ (6) const struct fs_parameter_enum *enums;
+
+ Table of enum value names to integer mappings, terminated with a null
+ entry. This is of type:
+
+ struct fs_parameter_enum {
+ u8 opt;
+ char name[14];
+ u8 value;
+ };
+
+ Where the array is an unsorted list of { parameter ID, name }-keyed
+ elements that indicate the value to map to, e.g.:
+
+ static const struct fs_parameter_enum afs_param_enums[] = {
+ { Opt_bar, "x", 1},
+ { Opt_bar, "y", 23},
+ { Opt_bar, "z", 42},
+ };
+
+ If a parameter of type fs_param_is_enum is encountered, fs_parse() will
+ try to look the value up in the enum table and the result will be stored
+ in the parse result.
+
+The parser should be pointed to by the parser pointer in the file_system_type
+struct as this will provide validation on registration (if
+CONFIG_VALIDATE_FS_PARSER=y) and will allow the description to be queried from
+userspace using the fsinfo() syscall.
+
+
+==========================
+PARAMETER HELPER FUNCTIONS
+==========================
+
+A number of helper functions are provided to help a filesystem or an LSM
+process the parameters it is given.
+
+ (*) int lookup_constant(const struct constant_table tbl[],
+ const char *name, int not_found);
+
+ Look up a constant by name in a table of name -> integer mappings. The
+ table is an array of elements of the following type:
+
+ struct constant_table {
+ const char *name;
+ int value;
+ };
+
+ If a match is found, the corresponding value is returned. If a match
+ isn't found, the not_found value is returned instead.
+
+ (*) bool validate_constant_table(const struct constant_table *tbl,
+ size_t tbl_size,
+ int low, int high, int special);
+
+ Validate a constant table. Checks that all the elements are appropriately
+ ordered, that there are no duplicates and that the values are between low
+ and high inclusive, though provision is made for one allowable special
+ value outside of that range. If no special value is required, special
+ should just be set to lie inside the low-to-high range.
+
+ If all is good, true is returned. If the table is invalid, errors are
+ logged to dmesg and false is returned.
+
+ (*) bool fs_validate_description(const struct fs_parameter_description *desc);
+
+ This performs some validation checks on a parameter description. It
+ returns true if the description is good and false if it is not. It will
+ log errors to dmesg if validation fails.
+
+ (*) int fs_parse(struct fs_context *fc,
+ const struct fs_parameter_description *desc,
+ struct fs_parameter *param,
+ struct fs_parse_result *result);
+
+ This is the main interpreter of parameters. It uses the parameter
+ description to look up a parameter by key name and to convert that to an
+ option number (which it returns).
+
+ If successful, and if the parameter type indicates the result is a
+ boolean, integer or enum type, the value is converted by this function and
+ the result stored in result->{boolean,int_32,uint_32,uint_64}.
+
+ If a match isn't initially made, the key is prefixed with "no" and no
+ value is present then an attempt will be made to look up the key with the
+ prefix removed. If this matches a parameter for which the type has flag
+ fs_param_neg_with_no set, then a match will be made and result->negated
+ will be set to true.
+
+ If the parameter isn't matched, -ENOPARAM will be returned; if the
+ parameter is matched, but the value is erroneous, -EINVAL will be
+ returned; otherwise the parameter's option number will be returned.
+
+ (*) int fs_lookup_param(struct fs_context *fc,
+ struct fs_parameter *value,
+ bool want_bdev,
+ struct path *_path);
+
+ This takes a parameter that carries a string or filename type and attempts
+ to do a path lookup on it. If the parameter expects a blockdev, a check
+ is made that the inode actually represents one.
+
+ Returns 0 if successful and *_path will be set; returns a negative error
+ code if not.

-Introduction
-------------
-
-The most obvious aspect of pathname lookup, which very little
-exploration is needed to discover, is that it is complex. There are
-many rules, special cases, and implementation alternatives that all
-combine to confuse the unwary reader. Computer science has long been
-acquainted with such complexity and has tools to help manage it. One
-tool that we will make extensive use of is "divide and conquer". For
-the early parts of the analysis we will divide off symlinks - leaving
-them until the final part. Well before we get to symlinks we have
-another major division based on the VFS's approach to locking which
-will allow us to review "REF-walk" and "RCU-walk" separately. But we
-are getting ahead of ourselves. There are some important low level
-distinctions we need to clarify first.
-
-There are two sorts of ...
---------------------------
-
-[`openat()`]: http://man7.org/linux/man-pages/man2/openat.2.html
-
-Pathnames (sometimes "file names"), used to identify objects in the
-filesystem, will be familiar to most readers. They contain two sorts
-of elements: "slashes" that are sequences of one or more "`/`"
-characters, and "components" that are sequences of one or more
-non-"`/`" characters. These form two kinds of paths. Those that
-start with slashes are "absolute" and start from the filesystem root.
-The others are "relative" and start from the current directory, or
-from some other location specified by a file descriptor given to a
-"xxx`at`" system call such as "[`openat()`]".
-
-[`execveat()`]: http://man7.org/linux/man-pages/man2/execveat.2.html
-
-It is tempting to describe the second kind as starting with a
-component, but that isn't always accurate: a pathname can lack both
-slashes and components, it can be empty, in other words. This is
-generally forbidden in POSIX, but some of those "xxx`at`" system calls
-in Linux permit it when the `AT_EMPTY_PATH` flag is given. For
-example, if you have an open file descriptor on an executable file you
-can execute it by calling [`execveat()`] passing the file descriptor,
-an empty path, and the `AT_EMPTY_PATH` flag.
-
-These paths can be divided into two sections: the final component and
-everything else. The "everything else" is the easy bit. In all cases
-it must identify a directory that already exists, otherwise an error
-such as `ENOENT` or `ENOTDIR` will be reported.
-
-The final component is not so simple. Not only do different system
-calls interpret it quite differently (e.g. some create it, some do
-not), but it might not even exist: neither the empty pathname nor the
-pathname that is just slashes have a final component. If it does
-exist, it could be "`.`" or "`..`" which are handled quite differently
-from other components.
-
-[POSIX]: http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap04.html#tag_04_12
-
-If a pathname ends with a slash, such as "`/tmp/foo/`" it might be
-tempting to consider that to have an empty final component. In many
-ways that would lead to correct results, but not always. In
-particular, `mkdir()` and `rmdir()` each create or remove a directory named
-by the final component, and they are required to work with pathnames
-ending in "`/`". According to [POSIX]
-
-> A pathname that contains at least one non- &lt;slash> character and
-> that ends with one or more trailing &lt;slash> characters shall not
-> be resolved successfully unless the last pathname component before
-> the trailing <slash> characters names an existing directory or a
-> directory entry that is to be created for a directory immediately
-> after the pathname is resolved.
-
-The Linux pathname walking code (mostly in `fs/namei.c`) deals with
-all of these issues: breaking the path into components, handling the
-"everything else" quite separately from the final component, and
-checking that the trailing slash is not used where it isn't
-permitted. It also addresses the important issue of concurrent
-access.
-
-While one process is looking up a pathname, another might be making
-changes that affect that lookup. One fairly extreme case is that if
-"a/b" were renamed to "a/c/b" while another process were looking up
-"a/b/..", that process might successfully resolve on "a/c".
-Most races are much more subtle, and a big part of the task of
-pathname lookup is to prevent them from having damaging effects. Many
-of the possible races are seen most clearly in the context of the
-"dcache" and an understanding of that is central to understanding
-pathname lookup.
-
-More than just a cache.
------------------------
-
-The "dcache" caches information about names in each filesystem to
-make them quickly available for lookup. Each entry (known as a
-"dentry") contains three significant fields: a component name, a
-pointer to a parent dentry, and a pointer to the "inode" which
-contains further information about the object in that parent with
-the given name. The inode pointer can be `NULL` indicating that the
-name doesn't exist in the parent. While there can be linkage in the
-dentry of a directory to the dentries of the children, that linkage is
-not used for pathname lookup, and so will not be considered here.
-
-The dcache has a number of uses apart from accelerating lookup. One
-that will be particularly relevant is that it is closely integrated
-with the mount table that records which filesystem is mounted where.
-What the mount table actually stores is which dentry is mounted on top
-of which other dentry.
-
-When considering the dcache, we have another of our "two types"
-distinctions: there are two types of filesystems.
-
-Some filesystems ensure that the information in the dcache is always
-completely accurate (though not necessarily complete). This can allow
-the VFS to determine if a particular file does or doesn't exist
-without checking with the filesystem, and means that the VFS can
-protect the filesystem against certain races and other problems.
-These are typically "local" filesystems such as ext3, XFS, and Btrfs.
-
-Other filesystems don't provide that guarantee because they cannot.
-These are typically filesystems that are shared across a network,
-whether remote filesystems like NFS and 9P, or cluster filesystems
-like ocfs2 or cephfs. These filesystems allow the VFS to revalidate
-cached information, and must provide their own protection against
-awkward races. The VFS can detect these filesystems by the
-`DCACHE_OP_REVALIDATE` flag being set in the dentry.
-
-REF-walk: simple concurrency management with refcounts and spinlocks
---------------------------------------------------------------------
-
-With all of those divisions carefully classified, we can now start
-looking at the actual process of walking along a path. In particular
-we will start with the handling of the "everything else" part of a
-pathname, and focus on the "REF-walk" approach to concurrency
-management. This code is found in the `link_path_walk()` function, if
-you ignore all the places that only run when "`LOOKUP_RCU`"
-(indicating the use of RCU-walk) is set.
-
-[Meet the Lockers]: https://lwn.net/Articles/453685/
-
-REF-walk is fairly heavy-handed with locks and reference counts. Not
-as heavy-handed as in the old "big kernel lock" days, but certainly not
-afraid of taking a lock when one is needed. It uses a variety of
-different concurrency controls. A background understanding of the
-various primitives is assumed, or can be gleaned from elsewhere such
-as in [Meet the Lockers].
-
-The locking mechanisms used by REF-walk include:
-
-### dentry->d_lockref ###
-
-This uses the lockref primitive to provide both a spinlock and a
-reference count. The special-sauce of this primitive is that the
-conceptual sequence "lock; inc_ref; unlock;" can often be performed
-with a single atomic memory operation.
-
-Holding a reference on a dentry ensures that the dentry won't suddenly
-be freed and used for something else, so the values in various fields
-will behave as expected. It also protects the `->d_inode` reference
-to the inode to some extent.
-
-The association between a dentry and its inode is fairly permanent.
-For example, when a file is renamed, the dentry and inode move
-together to the new location. When a file is created the dentry will
-initially be negative (i.e. `d_inode` is `NULL`), and will be assigned
-to the new inode as part of the act of creation.
-
-When a file is deleted, this can be reflected in the cache either by
-setting `d_inode` to `NULL`, or by removing it from the hash table
-(described shortly) used to look up the name in the parent directory.
-If the dentry is still in use the second option is used as it is
-perfectly legal to keep using an open file after it has been deleted
-and having the dentry around helps. If the dentry is not otherwise in
-use (i.e. if the refcount in `d_lockref` is one), only then will
-`d_inode` be set to `NULL`. Doing it this way is more efficient for a
-very common case.
-
-So as long as a counted reference is held to a dentry, a non-`NULL` `->d_inode`
-value will never be changed.
-
-### dentry->d_lock ###
-
-`d_lock` is a synonym for the spinlock that is part of `d_lockref` above.
-For our purposes, holding this lock protects against the dentry being
-renamed or unlinked. In particular, its parent (`d_parent`), and its
-name (`d_name`) cannot be changed, and it cannot be removed from the
-dentry hash table.
-
-When looking for a name in a directory, REF-walk takes `d_lock` on
-each candidate dentry that it finds in the hash table and then checks
-that the parent and name are correct. So it doesn't lock the parent
-while searching in the cache; it only locks children.
-
-When looking for the parent for a given name (to handle "`..`"),
-REF-walk can take `d_lock` to get a stable reference to `d_parent`,
-but it first tries a more lightweight approach. As seen in
-`dget_parent()`, if a reference can be claimed on the parent, and if
-subsequently `d_parent` can be seen to have not changed, then there is
-no need to actually take the lock on the child.
-
-### rename_lock ###
-
-Looking up a given name in a given directory involves computing a hash
-from the two values (the name and the dentry of the directory),
-accessing that slot in a hash table, and searching the linked list
-that is found there.
-
-When a dentry is renamed, the name and the parent dentry can both
-change so the hash will almost certainly change too. This would move the
-dentry to a different chain in the hash table. If a filename search
-happened to be looking at a dentry that was moved in this way,
-it might end up continuing the search down the wrong chain,
-and so miss out on part of the correct chain.
-
-The name-lookup process (`d_lookup()`) does _not_ try to prevent this
-from happening, but only to detect when it happens.
-`rename_lock` is a seqlock that is updated whenever any dentry is
-renamed. If `d_lookup` finds that a rename happened while it
-unsuccessfully scanned a chain in the hash table, it simply tries
-again.
-
-### inode->i_mutex ###
-
-`i_mutex` is a mutex that serializes all changes to a particular
-directory. This ensures that, for example, an `unlink()` and a `rename()`
-cannot both happen at the same time. It also keeps the directory
-stable while the filesystem is asked to look up a name that is not
-currently in the dcache.
-
-This has a complementary role to that of `d_lock`: `i_mutex` on a
-directory protects all of the names in that directory, while `d_lock`
-on a name protects just one name in a directory. Most changes to the
-dcache hold `i_mutex` on the relevant directory inode and briefly take
-`d_lock` on one or more the dentries while the change happens. One
-exception is when idle dentries are removed from the dcache due to
-memory pressure. This uses `d_lock`, but `i_mutex` plays no role.
-
-The mutex affects pathname lookup in two distinct ways. Firstly it
-serializes lookup of a name in a directory. `walk_component()` uses
-`lookup_fast()` first which, in turn, checks to see if the name is in the cache,
-using only `d_lock` locking. If the name isn't found, then `walk_component()`
-falls back to `lookup_slow()` which takes `i_mutex`, checks again that
-the name isn't in the cache, and then calls in to the filesystem to get a
-definitive answer. A new dentry will be added to the cache regardless of
-the result.
-
-Secondly, when pathname lookup reaches the final component, it will
-sometimes need to take `i_mutex` before performing the last lookup so
-that the required exclusion can be achieved. How path lookup chooses
-to take, or not take, `i_mutex` is one of the
-issues addressed in a subsequent section.
-
-### mnt->mnt_count ###
-
-`mnt_count` is a per-CPU reference counter on "`mount`" structures.
-Per-CPU here means that incrementing the count is cheap as it only
-uses CPU-local memory, but checking if the count is zero is expensive as
-it needs to check with every CPU. Taking a `mnt_count` reference
-prevents the mount structure from disappearing as the result of regular
-unmount operations, but does not prevent a "lazy" unmount. So holding
-`mnt_count` doesn't ensure that the mount remains in the namespace and,
-in particular, doesn't stabilize the link to the mounted-on dentry. It
-does, however, ensure that the `mount` data structure remains coherent,
-and it provides a reference to the root dentry of the mounted
-filesystem. So a reference through `->mnt_count` provides a stable
-reference to the mounted dentry, but not the mounted-on dentry.
-
-### mount_lock ###
-
-`mount_lock` is a global seqlock, a bit like `rename_lock`. It can be used to
-check if any change has been made to any mount points.
-
-While walking down the tree (away from the root) this lock is used when
-crossing a mount point to check that the crossing was safe. That is,
-the value in the seqlock is read, then the code finds the mount that
-is mounted on the current directory, if there is one, and increments
-the `mnt_count`. Finally the value in `mount_lock` is checked against
-the old value. If there is no change, then the crossing was safe. If there
-was a change, the `mnt_count` is decremented and the whole process is
-retried.
-
-When walking up the tree (towards the root) by following a ".." link,
-a little more care is needed. In this case the seqlock (which
-contains both a counter and a spinlock) is fully locked to prevent
-any changes to any mount points while stepping up. This locking is
-needed to stabilize the link to the mounted-on dentry, which the
-refcount on the mount itself doesn't ensure.
-
-### RCU ###
-
-Finally the global (but extremely lightweight) RCU read lock is held
-from time to time to ensure certain data structures don't get freed
-unexpectedly.
-
-In particular it is held while scanning chains in the dcache hash
-table, and the mount point hash table.
-
-Bringing it together with `struct nameidata`
---------------------------------------------
-
-[First edition Unix]: http://minnie.tuhs.org/cgi-bin/utree.pl?file=V1/u2.s
-
-Throughout the process of walking a path, the current status is stored
-in a `struct nameidata`, "namei" being the traditional name - dating
-all the way back to [First Edition Unix] - of the function that
-converts a "name" to an "inode". `struct nameidata` contains (among
-other fields):
-
-### `struct path path` ###
-
-A `path` contains a `struct vfsmount` (which is
-embedded in a `struct mount`) and a `struct dentry`. Together these
-record the current status of the walk. They start out referring to the
-starting point (the current working directory, the root directory, or some other
-directory identified by a file descriptor), and are updated on each
-step. A reference through `d_lockref` and `mnt_count` is always
-held.
-
-### `struct qstr last` ###
-
-This is a string together with a length (i.e. _not_ `nul` terminated)
-that is the "next" component in the pathname.
-
-### `int last_type` ###
-
-This is one of `LAST_NORM`, `LAST_ROOT`, `LAST_DOT`, `LAST_DOTDOT`, or
-`LAST_BIND`. The `last` field is only valid if the type is
-`LAST_NORM`. `LAST_BIND` is used when following a symlink and no
-components of the symlink have been processed yet. Others should be
-fairly self-explanatory.
-
-### `struct path root` ###
-
-This is used to hold a reference to the effective root of the
-filesystem. Often that reference won't be needed, so this field is
-only assigned the first time it is used, or when a non-standard root
-is requested. Keeping a reference in the `nameidata` ensures that
-only one root is in effect for the entire path walk, even if it races
-with a `chroot()` system call.
-
-The root is needed when either of two conditions holds: (1) either the
-pathname or a symbolic link starts with a "'/'", or (2) a "`..`"
-component is being handled, since "`..`" from the root must always stay
-at the root. The value used is usually the current root directory of
-the calling process. An alternate root can be provided as when
-`sysctl()` calls `file_open_root()`, and when NFSv4 or Btrfs call
-`mount_subtree()`. In each case a pathname is being looked up in a very
-specific part of the filesystem, and the lookup must not be allowed to
-escape that subtree. It works a bit like a local `chroot()`.
-
-Ignoring the handling of symbolic links, we can now describe the
-"`link_path_walk()`" function, which handles the lookup of everything
-except the final component as:
-
-> Given a path (`name`) and a nameidata structure (`nd`), check that the
-> current directory has execute permission and then advance `name`
-> over one component while updating `last_type` and `last`. If that
-> was the final component, then return, otherwise call
-> `walk_component()` and repeat from the top.
-
-`walk_component()` is even easier. If the component is `LAST_DOTS`,
-it calls `handle_dots()` which does the necessary locking as already
-described. If it finds a `LAST_NORM` component it first calls
-"`lookup_fast()`" which only looks in the dcache, but will ask the
-filesystem to revalidate the result if it is that sort of filesystem.
-If that doesn't get a good result, it calls "`lookup_slow()`" which
-takes the `i_mutex`, rechecks the cache, and then asks the filesystem
-to find a definitive answer. Each of these will call
-`follow_managed()` (as described below) to handle any mount points.
-
-In the absence of symbolic links, `walk_component()` creates a new
-`struct path` containing a counted reference to the new dentry and a
-reference to the new `vfsmount` which is only counted if it is
-different from the previous `vfsmount`. It then calls
-`path_to_nameidata()` to install the new `struct path` in the
-`struct nameidata` and drop the unneeded references.
-
-This "hand-over-hand" sequencing of getting a reference to the new
-dentry before dropping the reference to the previous dentry may
-seem obvious, but is worth pointing out so that we will recognize its
-analogue in the "RCU-walk" version.
-
-Handling the final component.
------------------------------
-
-`link_path_walk()` only walks as far as setting `nd->last` and
-`nd->last_type` to refer to the final component of the path. It does
-not call `walk_component()` that last time. Handling that final
-component remains for the caller to sort out. Those callers are
-`path_lookupat()`, `path_parentat()`, `path_mountpoint()` and
-`path_openat()` each of which handles the differing requirements of
-different system calls.
-
-`path_parentat()` is clearly the simplest - it just wraps a little bit
-of housekeeping around `link_path_walk()` and returns the parent
-directory and final component to the caller. The caller will be either
-aiming to create a name (via `filename_create()`) or remove or rename
-a name (in which case `user_path_parent()` is used). They will use
-`i_mutex` to exclude other changes while they validate and then
-perform their operation.
-
-`path_lookupat()` is nearly as simple - it is used when an existing
-object is wanted such as by `stat()` or `chmod()`. It essentially just
-calls `walk_component()` on the final component through a call to
-`lookup_last()`. `path_lookupat()` returns just the final dentry.
-
-`path_mountpoint()` handles the special case of unmounting which must
-not try to revalidate the mounted filesystem. It effectively
-contains, through a call to `mountpoint_last()`, an alternate
-implementation of `lookup_slow()` which skips that step. This is
-important when unmounting a filesystem that is inaccessible, such as
-one provided by a dead NFS server.
-
-Finally `path_openat()` is used for the `open()` system call; it
-contains, in support functions starting with "`do_last()`", all the
-complexity needed to handle the different subtleties of O_CREAT (with
-or without O_EXCL), final "`/`" characters, and trailing symbolic
-links. We will revisit this in the final part of this series, which
-focuses on those symbolic links. "`do_last()`" will sometimes, but
-not always, take `i_mutex`, depending on what it finds.
-
-Each of these, or the functions which call them, need to be alert to
-the possibility that the final component is not `LAST_NORM`. If the
-goal of the lookup is to create something, then any value for
-`last_type` other than `LAST_NORM` will result in an error. For
-example if `path_parentat()` reports `LAST_DOTDOT`, then the caller
-won't try to create that name. They also check for trailing slashes
-by testing `last.name[last.len]`. If there is any character beyond
-the final component, it must be a trailing slash.
-
-Revalidation and automounts
----------------------------
-
-Apart from symbolic links, there are only two parts of the "REF-walk"
-process not yet covered. One is the handling of stale cache entries
-and the other is automounts.
-
-On filesystems that require it, the lookup routines will call the
-`->d_revalidate()` dentry method to ensure that the cached information
-is current. This will often confirm validity or update a few details
-from a server. In some cases it may find that there has been change
-further up the path and that something that was thought to be valid
-previously isn't really. When this happens the lookup of the whole
-path is aborted and retried with the "`LOOKUP_REVAL`" flag set. This
-forces revalidation to be more thorough. We will see more details of
-this retry process in the next article.
-
-Automount points are locations in the filesystem where an attempt to
-lookup a name can trigger changes to how that lookup should be
-handled, in particular by mounting a filesystem there. These are
-covered in greater detail in autofs.txt in the Linux documentation
-tree, but a few notes specifically related to path lookup are in order
-here.
-
-The Linux VFS has a concept of "managed" dentries which is reflected
-in function names such as "`follow_managed()`". There are three
-potentially interesting things about these dentries corresponding
-to three different flags that might be set in `dentry->d_flags`:
-
-### `DCACHE_MANAGE_TRANSIT` ###
-
-If this flag has been set, then the filesystem has requested that the
-`d_manage()` dentry operation be called before handling any possible
-mount point. This can perform two particular services:
-
-It can block to avoid races. If an automount point is being
-unmounted, the `d_manage()` function will usually wait for that
-process to complete before letting the new lookup proceed and possibly
-trigger a new automount.
-
-It can selectively allow only some processes to transit through a
-mount point. When a server process is managing automounts, it may
-need to access a directory without triggering normal automount
-processing. That server process can identify itself to the `autofs`
-filesystem, which will then give it a special pass through
-`d_manage()` by returning `-EISDIR`.
-
-### `DCACHE_MOUNTED` ###
-
-This flag is set on every dentry that is mounted on. As Linux
-supports multiple filesystem namespaces, it is possible that the
-dentry may not be mounted on in *this* namespace, just in some
-other. So this flag is seen as a hint, not a promise.
-
-If this flag is set, and `d_manage()` didn't return `-EISDIR`,
-`lookup_mnt()` is called to examine the mount hash table (honoring the
-`mount_lock` described earlier) and possibly return a new `vfsmount`
-and a new `dentry` (both with counted references).
-
-### `DCACHE_NEED_AUTOMOUNT` ###
-
-If `d_manage()` allowed us to get this far, and `lookup_mnt()` didn't
-find a mount point, then this flag causes the `d_automount()` dentry
-operation to be called.
-
-The `d_automount()` operation can be arbitrarily complex and may
-communicate with server processes etc. but it should ultimately either
-report that there was an error, that there was nothing to mount, or
-should provide an updated `struct path` with new `dentry` and `vfsmount`.
-
-In the latter case, `finish_automount()` will be called to safely
-install the new mount point into the mount table.
-
-There is no new locking of import here and it is important that no
-locks (only counted references) are held over this processing due to
-the very real possibility of extended delays.
-This will become more important next time when we examine RCU-walk
-which is particularly sensitive to delays.
-
-RCU-walk - faster pathname lookup in Linux
-==========================================
-
-RCU-walk is another algorithm for performing pathname lookup in Linux.
-It is in many ways similar to REF-walk and the two share quite a bit
-of code. The significant difference in RCU-walk is how it allows for
-the possibility of concurrent access.
-
-We noted that REF-walk is complex because there are numerous details
-and special cases. RCU-walk reduces this complexity by simply
-refusing to handle a number of cases -- it instead falls back to
-REF-walk. The difficulty with RCU-walk comes from a different
-direction: unfamiliarity. The locking rules when depending on RCU are
-quite different from traditional locking, so we will spend a little extra
-time when we come to those.
-
-Clear demarcation of roles
---------------------------
-
-The easiest way to manage concurrency is to forcibly stop any other
-thread from changing the data structures that a given thread is
-looking at. In cases where no other thread would even think of
-changing the data and lots of different threads want to read at the
-same time, this can be very costly. Even when using locks that permit
-multiple concurrent readers, the simple act of updating the count of
-the number of current readers can impose an unwanted cost. So the
-goal when reading a shared data structure that no other process is
-changing is to avoid writing anything to memory at all. Take no
-locks, increment no counts, leave no footprints.
-
-The REF-walk mechanism already described certainly doesn't follow this
-principle, but then it is really designed to work when there may well
-be other threads modifying the data. RCU-walk, in contrast, is
-designed for the common situation where there are lots of frequent
-readers and only occasional writers. This may not be common in all
-parts of the filesystem tree, but in many parts it will be. For the
-other parts it is important that RCU-walk can quickly fall back to
-using REF-walk.
-
-Pathname lookup always starts in RCU-walk mode but only remains there
-as long as what it is looking for is in the cache and is stable. It
-dances lightly down the cached filesystem image, leaving no footprints
-and carefully watching where it is, to be sure it doesn't trip. If it
-notices that something has changed or is changing, or if something
-isn't in the cache, then it tries to stop gracefully and switch to
-REF-walk.
-
-This stopping requires getting a counted reference on the current
-`vfsmount` and `dentry`, and ensuring that these are still valid -
-that a path walk with REF-walk would have found the same entries.
-This is an invariant that RCU-walk must guarantee. It can only make
-decisions, such as selecting the next step, that are decisions which
-REF-walk could also have made if it were walking down the tree at the
-same time. If the graceful stop succeeds, the rest of the path is
-processed with the reliable, if slightly sluggish, REF-walk. If
-RCU-walk finds it cannot stop gracefully, it simply gives up and
-restarts from the top with REF-walk.
-
-This pattern of "try RCU-walk, if that fails try REF-walk" can be
-clearly seen in functions like `filename_lookup()`,
-`filename_parentat()`, `filename_mountpoint()`,
-`do_filp_open()`, and `do_file_open_root()`. These five
-correspond roughly to the four `path_`* functions we met earlier,
-each of which calls `link_path_walk()`. The `path_*` functions are
-called using different mode flags until a mode is found which works.
-They are first called with `LOOKUP_RCU` set to request "RCU-walk". If
-that fails with the error `ECHILD` they are called again with no
-special flag to request "REF-walk". If either of those report the
-error `ESTALE` a final attempt is made with `LOOKUP_REVAL` set (and no
-`LOOKUP_RCU`) to ensure that entries found in the cache are forcibly
-revalidated - normally entries are only revalidated if the filesystem
-determines that they are too old to trust.
-
-The `LOOKUP_RCU` attempt may drop that flag internally and switch to
-REF-walk, but will never then try to switch back to RCU-walk. Places
-that trip up RCU-walk are much more likely to be near the leaves and
-so it is very unlikely that there will be much, if any, benefit from
-switching back.
-
-RCU and seqlocks: fast and light
---------------------------------
-
-RCU is, unsurprisingly, critical to RCU-walk mode. The
-`rcu_read_lock()` is held for the entire time that RCU-walk is walking
-down a path. The particular guarantee it provides is that the key
-data structures - dentries, inodes, super_blocks, and mounts - will
-not be freed while the lock is held. They might be unlinked or
-invalidated in one way or another, but the memory will not be
-repurposed so values in various fields will still be meaningful. This
-is the only guarantee that RCU provides; everything else is done using
-seqlocks.
-
-As we saw above, REF-walk holds a counted reference to the current
-dentry and the current vfsmount, and does not release those references
-before taking references to the "next" dentry or vfsmount. It also
-sometimes takes the `d_lock` spinlock. These references and locks are
-taken to prevent certain changes from happening. RCU-walk must not
-take those references or locks and so cannot prevent such changes.
-Instead, it checks to see if a change has been made, and aborts or
-retries if it has.
-
-To preserve the invariant mentioned above (that RCU-walk may only make
-decisions that REF-walk could have made), it must make the checks at
-or near the same places that REF-walk holds the references. So, when
-REF-walk increments a reference count or takes a spinlock, RCU-walk
-samples the status of a seqlock using `read_seqcount_begin()` or a
-similar function. When REF-walk decrements the count or drops the
-lock, RCU-walk checks if the sampled status is still valid using
-`read_seqcount_retry()` or similar.
-
-However, there is a little bit more to seqlocks than that. If
-RCU-walk accesses two different fields in a seqlock-protected
-structure, or accesses the same field twice, there is no a priori
-guarantee of any consistency between those accesses. When consistency
-is needed - which it usually is - RCU-walk must take a copy and then
-use `read_seqcount_retry()` to validate that copy.
-
-`read_seqcount_retry()` not only checks the sequence number, but also
-imposes a memory barrier so that no memory-read instruction from
-*before* the call can be delayed until *after* the call, either by the
-CPU or by the compiler. A simple example of this can be seen in
-`slow_dentry_cmp()` which, for filesystems which do not use simple
-byte-wise name equality, calls into the filesystem to compare a name
-against a dentry. The length and name pointer are copied into local
-variables, then `read_seqcount_retry()` is called to confirm the two
-are consistent, and only then is `->d_compare()` called. When
-standard filename comparison is used, `dentry_cmp()` is called
-instead. Notably it does _not_ use `read_seqcount_retry()`, but
-instead has a large comment explaining why the consistency guarantee
-isn't necessary. A subsequent `read_seqcount_retry()` will be
-sufficient to catch any problem that could occur at this point.
-
-With that little refresher on seqlocks out of the way we can look at
-the bigger picture of how RCU-walk uses seqlocks.
-
-### `mount_lock` and `nd->m_seq` ###
-
-We already met the `mount_lock` seqlock when REF-walk used it to
-ensure that crossing a mount point is performed safely. RCU-walk uses
-it for that too, but for quite a bit more.
-
-Instead of taking a counted reference to each `vfsmount` as it
-descends the tree, RCU-walk samples the state of `mount_lock` at the
-start of the walk and stores this initial sequence number in the
-`struct nameidata` in the `m_seq` field. This one lock and one
-sequence number are used to validate all accesses to all `vfsmounts`,
-and all mount point crossings. As changes to the mount table are
-relatively rare, it is reasonable to fall back on REF-walk any time
-that any "mount" or "unmount" happens.
-
-`m_seq` is checked (using `read_seqretry()`) at the end of an RCU-walk
-sequence, whether switching to REF-walk for the rest of the path or
-when the end of the path is reached. It is also checked when stepping
-down over a mount point (in `__follow_mount_rcu()`) or up (in
-`follow_dotdot_rcu()`). If it is ever found to have changed, the
-whole RCU-walk sequence is aborted and the path is processed again by
-REF-walk.
-
-If RCU-walk finds that `mount_lock` hasn't changed then it can be sure
-that, had REF-walk taken counted references on each vfsmount, the
-results would have been the same. This ensures the invariant holds,
-at least for vfsmount structures.
-
-### `dentry->d_seq` and `nd->seq`. ###
-
-In place of taking a count or lock on `d_reflock`, RCU-walk samples
-the per-dentry `d_seq` seqlock, and stores the sequence number in the
-`seq` field of the nameidata structure, so `nd->seq` should always be
-the current sequence number of `nd->dentry`. This number needs to be
-revalidated after copying, and before using, the name, parent, or
-inode of the dentry.
-
-The handling of the name we have already looked at, and the parent is
-only accessed in `follow_dotdot_rcu()` which fairly trivially follows
-the required pattern, though it does so for three different cases.
-
-When not at a mount point, `d_parent` is followed and its `d_seq` is
-collected. When we are at a mount point, we instead follow the
-`mnt->mnt_mountpoint` link to get a new dentry and collect its
-`d_seq`. Then, after finally finding a `d_parent` to follow, we must
-check if we have landed on a mount point and, if so, must find that
-mount point and follow the `mnt->mnt_root` link. This would imply a
-somewhat unusual, but certainly possible, circumstance where the
-starting point of the path lookup was in part of the filesystem that
-was mounted on, and so not visible from the root.
-
-The inode pointer, stored in `->d_inode`, is a little more
-interesting. The inode will always need to be accessed at least
-twice, once to determine if it is NULL and once to verify access
-permissions. Symlink handling requires a validated inode pointer too.
-Rather than revalidating on each access, a copy is made on the first
-access and it is stored in the `inode` field of `nameidata` from where
-it can be safely accessed without further validation.
-
-`lookup_fast()` is the only lookup routine that is used in RCU-mode,
-`lookup_slow()` being too slow and requiring locks. It is in
-`lookup_fast()` that we find the important "hand over hand" tracking
-of the current dentry.
-
-The current `dentry` and current `seq` number are passed to
-`__d_lookup_rcu()` which, on success, returns a new `dentry` and a
-new `seq` number. `lookup_fast()` then copies the inode pointer and
-revalidates the new `seq` number. It then validates the old `dentry`
-with the old `seq` number one last time and only then continues. This
-process of getting the `seq` number of the new dentry and then
-checking the `seq` number of the old exactly mirrors the process of
-getting a counted reference to the new dentry before dropping that for
-the old dentry which we saw in REF-walk.
-
-### No `inode->i_mutex` or even `rename_lock` ###
-
-A mutex is a fairly heavyweight lock that can only be taken when it is
-permissible to sleep. As `rcu_read_lock()` forbids sleeping,
-`inode->i_mutex` plays no role in RCU-walk. If some other thread does
-take `i_mutex` and modifies the directory in a way that RCU-walk needs
-to notice, the result will be either that RCU-walk fails to find the
-dentry that it is looking for, or it will find a dentry which
-`read_seqretry()` won't validate. In either case it will drop down to
-REF-walk mode which can take whatever locks are needed.
-
-Though `rename_lock` could be used by RCU-walk as it doesn't require
-any sleeping, RCU-walk doesn't bother. REF-walk uses `rename_lock` to
-protect against the possibility of hash chains in the dcache changing
-while they are being searched. This can result in failing to find
-something that actually is there. When RCU-walk fails to find
-something in the dentry cache, whether it is really there or not, it
-already drops down to REF-walk and tries again with appropriate
-locking. This neatly handles all cases, so adding extra checks on
-rename_lock would bring no significant value.
-
-`unlazy walk()` and `complete_walk()`
--------------------------------------
-
-That "dropping down to REF-walk" typically involves a call to
-`unlazy_walk()`, so named because "RCU-walk" is also sometimes
-referred to as "lazy walk". `unlazy_walk()` is called when
-following the path down to the current vfsmount/dentry pair seems to
-have proceeded successfully, but the next step is problematic. This
-can happen if the next name cannot be found in the dcache, if
-permission checking or name revalidation couldn't be achieved while
-the `rcu_read_lock()` is held (which forbids sleeping), if an
-automount point is found, or in a couple of cases involving symlinks.
-It is also called from `complete_walk()` when the lookup has reached
-the final component, or the very end of the path, depending on which
-particular flavor of lookup is used.
-
-Other reasons for dropping out of RCU-walk that do not trigger a call
-to `unlazy_walk()` are when some inconsistency is found that cannot be
-handled immediately, such as `mount_lock` or one of the `d_seq`
-seqlocks reporting a change. In these cases the relevant function
-will return `-ECHILD` which will percolate up until it triggers a new
-attempt from the top using REF-walk.
-
-For those cases where `unlazy_walk()` is an option, it essentially
-takes a reference on each of the pointers that it holds (vfsmount,
-dentry, and possibly some symbolic links) and then verifies that the
-relevant seqlocks have not been changed. If there have been changes,
-it, too, aborts with `-ECHILD`, otherwise the transition to REF-walk
-has been a success and the lookup process continues.
-
-Taking a reference on those pointers is not quite as simple as just
-incrementing a counter. That works to take a second reference if you
-already have one (often indirectly through another object), but it
-isn't sufficient if you don't actually have a counted reference at
-all. For `dentry->d_lockref`, it is safe to increment the reference
-counter to get a reference unless it has been explicitly marked as
-"dead" which involves setting the counter to `-128`.
-`lockref_get_not_dead()` achieves this.
-
-For `mnt->mnt_count` it is safe to take a reference as long as
-`mount_lock` is then used to validate the reference. If that
-validation fails, it may *not* be safe to just drop that reference in
-the standard way of calling `mnt_put()` - an unmount may have
-progressed too far. So the code in `legitimize_mnt()`, when it
-finds that the reference it got might not be safe, checks the
-`MNT_SYNC_UMOUNT` flag to determine if a simple `mnt_put()` is
-correct, or if it should just decrement the count and pretend none of
-this ever happened.
-
-Taking care in filesystems
----------------------------
-
-RCU-walk depends almost entirely on cached information and often will
-not call into the filesystem at all. However there are two places,
-besides the already-mentioned component-name comparison, where the
-file system might be included in RCU-walk, and it must know to be
-careful.
-
-If the filesystem has non-standard permission-checking requirements -
-such as a networked filesystem which may need to check with the server
-- the `i_op->permission` interface might be called during RCU-walk.
-In this case an extra "`MAY_NOT_BLOCK`" flag is passed so that it
-knows not to sleep, but to return `-ECHILD` if it cannot complete
-promptly. `i_op->permission` is given the inode pointer, not the
-dentry, so it doesn't need to worry about further consistency checks.
-However if it accesses any other filesystem data structures, it must
-ensure they are safe to be accessed with only the `rcu_read_lock()`
-held. This typically means they must be freed using `kfree_rcu()` or
-similar.
-
-[`READ_ONCE()`]: https://lwn.net/Articles/624126/
-
-If the filesystem may need to revalidate dcache entries, then
-`d_op->d_revalidate` may be called in RCU-walk too. This interface
-*is* passed the dentry but does not have access to the `inode` or the
-`seq` number from the `nameidata`, so it needs to be extra careful
-when accessing fields in the dentry. This "extra care" typically
-involves using [`READ_ONCE()`] to access fields, and verifying the
-result is not NULL before using it. This pattern can be seen in
-`nfs_lookup_revalidate()`.
-
-A pair of patterns
-------------------
-
-In various places in the details of REF-walk and RCU-walk, and also in
-the big picture, there are a couple of related patterns that are worth
-being aware of.
-
-The first is "try quickly and check, if that fails try slowly". We
-can see that in the high-level approach of first trying RCU-walk and
-then trying REF-walk, and in places where `unlazy_walk()` is used to
-switch to REF-walk for the rest of the path. We also saw it earlier
-in `dget_parent()` when following a "`..`" link. It tries a quick way
-to get a reference, then falls back to taking locks if needed.
-
-The second pattern is "try quickly and check, if that fails try
-again - repeatedly". This is seen with the use of `rename_lock` and
-`mount_lock` in REF-walk. RCU-walk doesn't make use of this pattern -
-if anything goes wrong it is much safer to just abort and try a more
-sedate approach.
-
-The emphasis here is "try quickly and check". It should probably be
-"try quickly _and carefully,_ then check". The fact that checking is
-needed is a reminder that the system is dynamic and only a limited
-number of things are safe at all. The most likely cause of errors in
-this whole process is assuming something is safe when in reality it
-isn't. Careful consideration of what exactly guarantees the safety of
-each access is sometimes necessary.
-
-A walk among the symlinks
-=========================
-
-There are several basic issues that we will examine to understand the
-handling of symbolic links: the symlink stack, together with cache
-lifetimes, will help us understand the overall recursive handling of
-symlinks and lead to the special care needed for the final component.
-Then a consideration of access-time updates and summary of the various
-flags controlling lookup will finish the story.
-
-The symlink stack
------------------
-
-There are only two sorts of filesystem objects that can usefully
-appear in a path prior to the final component: directories and symlinks.
-Handling directories is quite straightforward: the new directory
-simply becomes the starting point at which to interpret the next
-component on the path. Handling symbolic links requires a bit more
-work.
-
-Conceptually, symbolic links could be handled by editing the path. If
-a component name refers to a symbolic link, then that component is
-replaced by the body of the link and, if that body starts with a '/',
-then all preceding parts of the path are discarded. This is what the
-"`readlink -f`" command does, though it also edits out "`.`" and
-"`..`" components.
-
-Directly editing the path string is not really necessary when looking
-up a path, and discarding early components is pointless as they aren't
-looked at anyway. Keeping track of all remaining components is
-important, but they can of course be kept separately; there is no need
-to concatenate them. As one symlink may easily refer to another,
-which in turn can refer to a third, we may need to keep the remaining
-components of several paths, each to be processed when the preceding
-ones are completed. These path remnants are kept on a stack of
-limited size.
-
-There are two reasons for placing limits on how many symlinks can
-occur in a single path lookup. The most obvious is to avoid loops.
-If a symlink referred to itself either directly or through
-intermediaries, then following the symlink can never complete
-successfully - the error `ELOOP` must be returned. Loops can be
-detected without imposing limits, but limits are the simplest solution
-and, given the second reason for restriction, quite sufficient.
-
-[outlined recently]: http://thread.gmane.org/gmane.linux.kernel/1934390/focus=1934550
-
-The second reason was [outlined recently] by Linus:
-
-> Because it's a latency and DoS issue too. We need to react well to
-> true loops, but also to "very deep" non-loops. It's not about memory
-> use, it's about users triggering unreasonable CPU resources.
-
-Linux imposes a limit on the length of any pathname: `PATH_MAX`, which
-is 4096. There are a number of reasons for this limit; not letting the
-kernel spend too much time on just one path is one of them. With
-symbolic links you can effectively generate much longer paths so some
-sort of limit is needed for the same reason. Linux imposes a limit of
-at most 40 symlinks in any one path lookup. It previously imposed a
-further limit of eight on the maximum depth of recursion, but that was
-raised to 40 when a separate stack was implemented, so there is now
-just the one limit.
-
-The `nameidata` structure that we met in an earlier article contains a
-small stack that can be used to store the remaining part of up to two
-symlinks. In many cases this will be sufficient. If it isn't, a
-separate stack is allocated with room for 40 symlinks. Pathname
-lookup will never exceed that stack as, once the 40th symlink is
-detected, an error is returned.
-
-It might seem that the name remnants are all that needs to be stored on
-this stack, but we need a bit more. To see that, we need to move on to
-cache lifetimes.
-
-Storage and lifetime of cached symlinks
----------------------------------------
-
-Like other filesystem resources, such as inodes and directory
-entries, symlinks are cached by Linux to avoid repeated costly access
-to external storage. It is particularly important for RCU-walk to be
-able to find and temporarily hold onto these cached entries, so that
-it doesn't need to drop down into REF-walk.
-
-[object-oriented design pattern]: https://lwn.net/Articles/446317/
-
-While each filesystem is free to make its own choice, symlinks are
-typically stored in one of two places. Short symlinks are often
-stored directly in the inode. When a filesystem allocates a `struct
-inode` it typically allocates extra space to store private data (a
-common [object-oriented design pattern] in the kernel). This will
-sometimes include space for a symlink. The other common location is
-in the page cache, which normally stores the content of files. The
-pathname in a symlink can be seen as the content of that symlink and
-can easily be stored in the page cache just like file content.
-
-When neither of these is suitable, the next most likely scenario is
-that the filesystem will allocate some temporary memory and copy or
-construct the symlink content into that memory whenever it is needed.
-
-When the symlink is stored in the inode, it has the same lifetime as
-the inode which, itself, is protected by RCU or by a counted reference
-on the dentry. This means that the mechanisms that pathname lookup
-uses to access the dcache and icache (inode cache) safely are quite
-sufficient for accessing some cached symlinks safely. In these cases,
-the `i_link` pointer in the inode is set to point to wherever the
-symlink is stored and it can be accessed directly whenever needed.
-
-When the symlink is stored in the page cache or elsewhere, the
-situation is not so straightforward. A reference on a dentry or even
-on an inode does not imply any reference on cached pages of that
-inode, and even an `rcu_read_lock()` is not sufficient to ensure that
-a page will not disappear. So for these symlinks the pathname lookup
-code needs to ask the filesystem to provide a stable reference and,
-significantly, needs to release that reference when it is finished
-with it.
-
-Taking a reference to a cache page is often possible even in RCU-walk
-mode. It does require making changes to memory, which is best avoided,
-but that isn't necessarily a big cost and it is better than dropping
-out of RCU-walk mode completely. Even filesystems that allocate
-space to copy the symlink into can use `GFP_ATOMIC` to often successfully
-allocate memory without the need to drop out of RCU-walk. If a
-filesystem cannot successfully get a reference in RCU-walk mode, it
-must return `-ECHILD` and `unlazy_walk()` will be called to return to
-REF-walk mode in which the filesystem is allowed to sleep.
-
-The place for all this to happen is the `i_op->follow_link()` inode
-method. In the present mainline code this is never actually called in
-RCU-walk mode as the rewrite is not quite complete. It is likely that
-in a future release this method will be passed an `inode` pointer when
-called in RCU-walk mode so it both (1) knows to be careful, and (2) has the
-validated pointer. Much like the `i_op->permission()` method we
-looked at previously, `->follow_link()` would need to be careful that
-all the data structures it references are safe to be accessed while
-holding no counted reference, only the RCU lock. Though getting a
-reference with `->follow_link()` is not yet done in RCU-walk mode, the
-code is ready to release the reference when that does happen.
-
-This need to drop the reference to a symlink adds significant
-complexity. It requires a reference to the inode so that the
-`i_op->put_link()` inode operation can be called. In REF-walk, that
-reference is kept implicitly through a reference to the dentry, so
-keeping the `struct path` of the symlink is easiest. For RCU-walk,
-the pointer to the inode is kept separately. To allow switching from
-RCU-walk back to REF-walk in the middle of processing nested symlinks
-we also need the seq number for the dentry so we can confirm that
-switching back was safe.
-
-Finally, when providing a reference to a symlink, the filesystem also
-provides an opaque "cookie" that must be passed to `->put_link()` so that it
-knows what to free. This might be the allocated memory area, or a
-pointer to the `struct page` in the page cache, or something else
-completely. Only the filesystem knows what it is.
-
-In order for the reference to each symlink to be dropped when the walk completes,
-whether in RCU-walk or REF-walk, the symlink stack needs to contain,
-along with the path remnants:
-
-- the `struct path` to provide a reference to the inode in REF-walk
-- the `struct inode *` to provide a reference to the inode in RCU-walk
-- the `seq` to allow the path to be safely switched from RCU-walk to REF-walk
-- the `cookie` that tells `->put_path()` what to put.
-
-This means that each entry in the symlink stack needs to hold five
-pointers and an integer instead of just one pointer (the path
-remnant). On a 64-bit system, this is about 40 bytes per entry;
-with 40 entries it adds up to 1600 bytes total, which is less than
-half a page. So it might seem like a lot, but is by no means
-excessive.
-
-Note that, in a given stack frame, the path remnant (`name`) is not
-part of the symlink that the other fields refer to. It is the remnant
-to be followed once that symlink has been fully parsed.
-
-Following the symlink
----------------------
-
-The main loop in `link_path_walk()` iterates seamlessly over all
-components in the path and all of the non-final symlinks. As symlinks
-are processed, the `name` pointer is adjusted to point to a new
-symlink, or is restored from the stack, so that much of the loop
-doesn't need to notice. Getting this `name` variable on and off the
-stack is very straightforward; pushing and popping the references is
-a little more complex.
-
-When a symlink is found, `walk_component()` returns the value `1`
-(`0` is returned for any other sort of success, and a negative number
-is, as usual, an error indicator). This causes `get_link()` to be
-called; it then gets the link from the filesystem. Providing that
-operation is successful, the old path `name` is placed on the stack,
-and the new value is used as the `name` for a while. When the end of
-the path is found (i.e. `*name` is `'\0'`) the old `name` is restored
-off the stack and path walking continues.
-
-Pushing and popping the reference pointers (inode, cookie, etc.) is more
-complex in part because of the desire to handle tail recursion. When
-the last component of a symlink itself points to a symlink, we
-want to pop the symlink-just-completed off the stack before pushing
-the symlink-just-found to avoid leaving empty path remnants that would
-just get in the way.
-
-It is most convenient to push the new symlink references onto the
-stack in `walk_component()` immediately when the symlink is found;
-`walk_component()` is also the last piece of code that needs to look at the
-old symlink as it walks that last component. So it is quite
-convenient for `walk_component()` to release the old symlink and pop
-the references just before pushing the reference information for the
-new symlink. It is guided in this by two flags; `WALK_GET`, which
-gives it permission to follow a symlink if it finds one, and
-`WALK_PUT`, which tells it to release the current symlink after it has been
-followed. `WALK_PUT` is tested first, leading to a call to
-`put_link()`. `WALK_GET` is tested subsequently (by
-`should_follow_link()`) leading to a call to `pick_link()` which sets
-up the stack frame.
-
-### Symlinks with no final component ###
-
-A pair of special-case symlinks deserve a little further explanation.
-Both result in a new `struct path` (with mount and dentry) being set
-up in the `nameidata`, and result in `get_link()` returning `NULL`.
-
-The more obvious case is a symlink to "`/`". All symlinks starting
-with "`/`" are detected in `get_link()` which resets the `nameidata`
-to point to the effective filesystem root. If the symlink only
-contains "`/`" then there is nothing more to do, no components at all,
-so `NULL` is returned to indicate that the symlink can be released and
-the stack frame discarded.
-
-The other case involves things in `/proc` that look like symlinks but
-aren't really.
-
-> $ ls -l /proc/self/fd/1
-> lrwx------ 1 neilb neilb 64 Jun 13 10:19 /proc/self/fd/1 -> /dev/pts/4
-
-Every open file descriptor in any process is represented in `/proc` by
-something that looks like a symlink. It is really a reference to the
-target file, not just the name of it. When you `readlink` these
-objects you get a name that might refer to the same file - unless it
-has been unlinked or mounted over. When `walk_component()` follows
-one of these, the `->follow_link()` method in "procfs" doesn't return
-a string name, but instead calls `nd_jump_link()` which updates the
-`nameidata` in place to point to that target. `->follow_link()` then
-returns `NULL`. Again there is no final component and `get_link()`
-reports this by leaving the `last_type` field of `nameidata` as
-`LAST_BIND`.
-
-Following the symlink in the final component
---------------------------------------------
-
-All this leads to `link_path_walk()` walking down every component, and
-following all symbolic links it finds, until it reaches the final
-component. This is just returned in the `last` field of `nameidata`.
-For some callers, this is all they need; they want to create that
-`last` name if it doesn't exist or give an error if it does. Other
-callers will want to follow a symlink if one is found, and possibly
-apply special handling to the last component of that symlink, rather
-than just the last component of the original file name. These callers
-potentially need to call `link_path_walk()` again and again on
-successive symlinks until one is found that doesn't point to another
-symlink.
-
-This case is handled by the relevant caller of `link_path_walk()`, such as
-`path_lookupat()` using a loop that calls `link_path_walk()`, and then
-handles the final component. If the final component is a symlink
-that needs to be followed, then `trailing_symlink()` is called to set
-things up properly and the loop repeats, calling `link_path_walk()`
-again. This could loop as many as 40 times if the last component of
-each symlink is another symlink.
-
-The various functions that examine the final component and possibly
-report that it is a symlink are `lookup_last()`, `mountpoint_last()`
-and `do_last()`, each of which use the same convention as
-`walk_component()` of returning `1` if a symlink was found that needs
-to be followed.
-
-Of these, `do_last()` is the most interesting as it is used for
-opening a file. Part of `do_last()` runs with `i_mutex` held and this
-part is in a separate function: `lookup_open()`.
-
-Explaining `do_last()` completely is beyond the scope of this article,
-but a few highlights should help those interested in exploring the
-code.
-
-1. Rather than just finding the target file, `do_last()` needs to open
- it. If the file was found in the dcache, then `vfs_open()` is used for
- this. If not, then `lookup_open()` will either call `atomic_open()` (if
- the filesystem provides it) to combine the final lookup with the open, or
- will perform the separate `lookup_real()` and `vfs_create()` steps
- directly. In the later case the actual "open" of this newly found or
- created file will be performed by `vfs_open()`, just as if the name
- were found in the dcache.
-
-2. `vfs_open()` can fail with `-EOPENSTALE` if the cached information
- wasn't quite current enough. Rather than restarting the lookup from
- the top with `LOOKUP_REVAL` set, `lookup_open()` is called instead,
- giving the filesystem a chance to resolve small inconsistencies.
- If that doesn't work, only then is the lookup restarted from the top.
-
-3. An open with O_CREAT **does** follow a symlink in the final component,
- unlike other creation system calls (like `mkdir`). So the sequence:
-
- > ln -s bar /tmp/foo
- > echo hello > /tmp/foo
-
- will create a file called `/tmp/bar`. This is not permitted if
- `O_EXCL` is set but otherwise is handled for an O_CREAT open much
- like for a non-creating open: `should_follow_link()` returns `1`, and
- so does `do_last()` so that `trailing_symlink()` gets called and the
- open process continues on the symlink that was found.
-
-Updating the access time
-------------------------
-
-We previously said of RCU-walk that it would "take no locks, increment
-no counts, leave no footprints." We have since seen that some
-"footprints" can be needed when handling symlinks as a counted
-reference (or even a memory allocation) may be needed. But these
-footprints are best kept to a minimum.
-
-One other place where walking down a symlink can involve leaving
-footprints in a way that doesn't affect directories is in updating access times.
-In Unix (and Linux) every filesystem object has a "last accessed
-time", or "`atime`". Passing through a directory to access a file
-within is not considered to be an access for the purposes of
-`atime`; only listing the contents of a directory can update its `atime`.
-Symlinks are different it seems. Both reading a symlink (with `readlink()`)
-and looking up a symlink on the way to some other destination can
-update the atime on that symlink.
-
-[clearest statement]: http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap04.html#tag_04_08
-
-It is not clear why this is the case; POSIX has little to say on the
-subject. The [clearest statement] is that, if a particular implementation
-updates a timestamp in a place not specified by POSIX, this must be
-documented "except that any changes caused by pathname resolution need
-not be documented". This seems to imply that POSIX doesn't really
-care about access-time updates during pathname lookup.
-
-[Linux 1.3.87]: https://git.kernel.org/cgit/linux/kernel/git/history/history.git/diff/fs/ext2/symlink.c?id=f806c6db77b8eaa6e00dcfb6b567706feae8dbb8
-
-An examination of history shows that prior to [Linux 1.3.87], the ext2
-filesystem, at least, didn't update atime when following a link.
-Unfortunately we have no record of why that behavior was changed.
-
-In any case, access time must now be updated and that operation can be
-quite complex. Trying to stay in RCU-walk while doing it is best
-avoided. Fortunately it is often permitted to skip the `atime`
-update. Because `atime` updates cause performance problems in various
-areas, Linux supports the `relatime` mount option, which generally
-limits the updates of `atime` to once per day on files that aren't
-being changed (and symlinks never change once created). Even without
-`relatime`, many filesystems record `atime` with a one-second
-granularity, so only one update per second is required.
-
-It is easy to test if an `atime` update is needed while in RCU-walk
-mode and, if it isn't, the update can be skipped and RCU-walk mode
-continues. Only when an `atime` update is actually required does the
-path walk drop down to REF-walk. All of this is handled in the
-`get_link()` function.
-
-A few flags
------------
-
-A suitable way to wrap up this tour of pathname walking is to list
-the various flags that can be stored in the `nameidata` to guide the
-lookup process. Many of these are only meaningful on the final
-component, others reflect the current state of the pathname lookup.
-And then there is `LOOKUP_EMPTY`, which doesn't fit conceptually with
-the others. If this is not set, an empty pathname causes an error
-very early on. If it is set, empty pathnames are not considered to be
-an error.
-
-### Global state flags ###
-
-We have already met two global state flags: `LOOKUP_RCU` and
-`LOOKUP_REVAL`. These select between one of three overall approaches
-to lookup: RCU-walk, REF-walk, and REF-walk with forced revalidation.
-
-`LOOKUP_PARENT` indicates that the final component hasn't been reached
-yet. This is primarily used to tell the audit subsystem the full
-context of a particular access being audited.
-
-`LOOKUP_ROOT` indicates that the `root` field in the `nameidata` was
-provided by the caller, so it shouldn't be released when it is no
-longer needed.
-
-`LOOKUP_JUMPED` means that the current dentry was chosen not because
-it had the right name but for some other reason. This happens when
-following "`..`", following a symlink to `/`, crossing a mount point
-or accessing a "`/proc/$PID/fd/$FD`" symlink. In this case the
-filesystem has not been asked to revalidate the name (with
-`d_revalidate()`). In such cases the inode may still need to be
-revalidated, so `d_op->d_weak_revalidate()` is called if
-`LOOKUP_JUMPED` is set when the look completes - which may be at the
-final component or, when creating, unlinking, or renaming, at the penultimate component.
-
-### Final-component flags ###
-
-Some of these flags are only set when the final component is being
-considered. Others are only checked for when considering that final
-component.
-
-`LOOKUP_AUTOMOUNT` ensures that, if the final component is an automount
-point, then the mount is triggered. Some operations would trigger it
-anyway, but operations like `stat()` deliberately don't. `statfs()`
-needs to trigger the mount but otherwise behaves a lot like `stat()`, so
-it sets `LOOKUP_AUTOMOUNT`, as does "`quotactl()`" and the handling of
-"`mount --bind`".
-
-`LOOKUP_FOLLOW` has a similar function to `LOOKUP_AUTOMOUNT` but for
-symlinks. Some system calls set or clear it implicitly, while
-others have API flags such as `AT_SYMLINK_FOLLOW` and
-`UMOUNT_NOFOLLOW` to control it. Its effect is similar to

+
+Introduction to pathname lookup
+===============================
+
+The most obvious aspect of pathname lookup, which very little
+exploration is needed to discover, is that it is complex. There are
+many rules, special cases, and implementation alternatives that all
+combine to confuse the unwary reader. Computer science has long been
+acquainted with such complexity and has tools to help manage it. One
+tool that we will make extensive use of is "divide and conquer". For
+the early parts of the analysis we will divide off symlinks - leaving
+them until the final part. Well before we get to symlinks we have
+another major division based on the VFS's approach to locking which
+will allow us to review "REF-walk" and "RCU-walk" separately. But we
+are getting ahead of ourselves. There are some important low level
+distinctions we need to clarify first.
+
+There are two sorts of ...
+--------------------------
+
+.. _openat: http://man7.org/linux/man-pages/man2/openat.2.html
+
+Pathnames (sometimes "file names"), used to identify objects in the
+filesystem, will be familiar to most readers. They contain two sorts
+of elements: "slashes" that are sequences of one or more "``/``"
+characters, and "components" that are sequences of one or more
+non-"``/``" characters. These form two kinds of paths. Those that
+start with slashes are "absolute" and start from the filesystem root.
+The others are "relative" and start from the current directory, or
+from some other location specified by a file descriptor given to a
+"``XXXat``" system call such as `openat() <openat_>`_.
+
+.. _execveat: http://man7.org/linux/man-pages/man2/execveat.2.html
+
+It is tempting to describe the second kind as starting with a
+component, but that isn't always accurate: a pathname can lack both
+slashes and components, it can be empty, in other words. This is
+generally forbidden in POSIX, but some of those "xxx``at``" system calls
+in Linux permit it when the ``AT_EMPTY_PATH`` flag is given. For
+example, if you have an open file descriptor on an executable file you
+can execute it by calling `execveat() <execveat_>`_ passing
+the file descriptor, an empty path, and the ``AT_EMPTY_PATH`` flag.
+
+These paths can be divided into two sections: the final component and
+everything else. The "everything else" is the easy bit. In all cases
+it must identify a directory that already exists, otherwise an error
+such as ``ENOENT`` or ``ENOTDIR`` will be reported.
+
+The final component is not so simple. Not only do different system
+calls interpret it quite differently (e.g. some create it, some do
+not), but it might not even exist: neither the empty pathname nor the
+pathname that is just slashes have a final component. If it does
+exist, it could be "``.``" or "``..``" which are handled quite differently
+from other components.
+
+.. _POSIX: http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap04.html#tag_04_12
+
+If a pathname ends with a slash, such as "``/tmp/foo/``" it might be
+tempting to consider that to have an empty final component. In many
+ways that would lead to correct results, but not always. In
+particular, ``mkdir()`` and ``rmdir()`` each create or remove a directory named
+by the final component, and they are required to work with pathnames
+ending in "``/``". According to POSIX_
+
+ A pathname that contains at least one non- &lt;slash> character and
+ that ends with one or more trailing &lt;slash> characters shall not
+ be resolved successfully unless the last pathname component before
+ the trailing <slash> characters names an existing directory or a
+ directory entry that is to be created for a directory immediately
+ after the pathname is resolved.
+
+The Linux pathname walking code (mostly in ``fs/namei.c``) deals with
+all of these issues: breaking the path into components, handling the
+"everything else" quite separately from the final component, and
+checking that the trailing slash is not used where it isn't
+permitted. It also addresses the important issue of concurrent
+access.
+
+While one process is looking up a pathname, another might be making
+changes that affect that lookup. One fairly extreme case is that if
+"a/b" were renamed to "a/c/b" while another process were looking up
+"a/b/..", that process might successfully resolve on "a/c".
+Most races are much more subtle, and a big part of the task of
+pathname lookup is to prevent them from having damaging effects. Many
+of the possible races are seen most clearly in the context of the
+"dcache" and an understanding of that is central to understanding
+pathname lookup.
+
+More than just a cache
+----------------------
+
+The "dcache" caches information about names in each filesystem to
+make them quickly available for lookup. Each entry (known as a
+"dentry") contains three significant fields: a component name, a
+pointer to a parent dentry, and a pointer to the "inode" which
+contains further information about the object in that parent with
+the given name. The inode pointer can be ``NULL`` indicating that the
+name doesn't exist in the parent. While there can be linkage in the
+dentry of a directory to the dentries of the children, that linkage is
+not used for pathname lookup, and so will not be considered here.
+
+The dcache has a number of uses apart from accelerating lookup. One
+that will be particularly relevant is that it is closely integrated
+with the mount table that records which filesystem is mounted where.
+What the mount table actually stores is which dentry is mounted on top
+of which other dentry.
+
+When considering the dcache, we have another of our "two types"
+distinctions: there are two types of filesystems.
+
+Some filesystems ensure that the information in the dcache is always
+completely accurate (though not necessarily complete). This can allow
+the VFS to determine if a particular file does or doesn't exist
+without checking with the filesystem, and means that the VFS can
+protect the filesystem against certain races and other problems.
+These are typically "local" filesystems such as ext3, XFS, and Btrfs.
+
+Other filesystems don't provide that guarantee because they cannot.
+These are typically filesystems that are shared across a network,
+whether remote filesystems like NFS and 9P, or cluster filesystems
+like ocfs2 or cephfs. These filesystems allow the VFS to revalidate
+cached information, and must provide their own protection against
+awkward races. The VFS can detect these filesystems by the
+``DCACHE_OP_REVALIDATE`` flag being set in the dentry.
+
+REF-walk: simple concurrency management with refcounts and spinlocks
+--------------------------------------------------------------------
+
+With all of those divisions carefully classified, we can now start
+looking at the actual process of walking along a path. In particular
+we will start with the handling of the "everything else" part of a
+pathname, and focus on the "REF-walk" approach to concurrency
+management. This code is found in the ``link_path_walk()`` function, if
+you ignore all the places that only run when "``LOOKUP_RCU``"
+(indicating the use of RCU-walk) is set.
+
+.. _Meet the Lockers: https://lwn.net/Articles/453685/
+
+REF-walk is fairly heavy-handed with locks and reference counts. Not
+as heavy-handed as in the old "big kernel lock" days, but certainly not
+afraid of taking a lock when one is needed. It uses a variety of
+different concurrency controls. A background understanding of the
+various primitives is assumed, or can be gleaned from elsewhere such
+as in `Meet the Lockers`_.
+
+The locking mechanisms used by REF-walk include:
+
+dentry->d_lockref
+~~~~~~~~~~~~~~~~~
+
+This uses the lockref primitive to provide both a spinlock and a
+reference count. The special-sauce of this primitive is that the
+conceptual sequence "lock; inc_ref; unlock;" can often be performed
+with a single atomic memory operation.
+
+Holding a reference on a dentry ensures that the dentry won't suddenly
+be freed and used for something else, so the values in various fields
+will behave as expected. It also protects the ``->d_inode`` reference
+to the inode to some extent.
+
+The association between a dentry and its inode is fairly permanent.
+For example, when a file is renamed, the dentry and inode move
+together to the new location. When a file is created the dentry will
+initially be negative (i.e. ``d_inode`` is ``NULL``), and will be assigned
+to the new inode as part of the act of creation.
+
+When a file is deleted, this can be reflected in the cache either by
+setting ``d_inode`` to ``NULL``, or by removing it from the hash table
+(described shortly) used to look up the name in the parent directory.
+If the dentry is still in use the second option is used as it is
+perfectly legal to keep using an open file after it has been deleted
+and having the dentry around helps. If the dentry is not otherwise in
+use (i.e. if the refcount in ``d_lockref`` is one), only then will
+``d_inode`` be set to ``NULL``. Doing it this way is more efficient for a
+very common case.
+
+So as long as a counted reference is held to a dentry, a non-``NULL`` ``->d_inode``
+value will never be changed.
+
+dentry->d_lock
+~~~~~~~~~~~~~~
+
+``d_lock`` is a synonym for the spinlock that is part of ``d_lockref`` above.
+For our purposes, holding this lock protects against the dentry being
+renamed or unlinked. In particular, its parent (``d_parent``), and its
+name (``d_name``) cannot be changed, and it cannot be removed from the
+dentry hash table.
+
+When looking for a name in a directory, REF-walk takes ``d_lock`` on
+each candidate dentry that it finds in the hash table and then checks
+that the parent and name are correct. So it doesn't lock the parent
+while searching in the cache; it only locks children.
+
+When looking for the parent for a given name (to handle "``..``"),
+REF-walk can take ``d_lock`` to get a stable reference to ``d_parent``,
+but it first tries a more lightweight approach. As seen in
+``dget_parent()``, if a reference can be claimed on the parent, and if
+subsequently ``d_parent`` can be seen to have not changed, then there is
+no need to actually take the lock on the child.
+
+rename_lock
+~~~~~~~~~~~
+
+Looking up a given name in a given directory involves computing a hash
+from the two values (the name and the dentry of the directory),
+accessing that slot in a hash table, and searching the linked list
+that is found there.
+
+When a dentry is renamed, the name and the parent dentry can both
+change so the hash will almost certainly change too. This would move the
+dentry to a different chain in the hash table. If a filename search
+happened to be looking at a dentry that was moved in this way,
+it might end up continuing the search down the wrong chain,
+and so miss out on part of the correct chain.
+
+The name-lookup process (``d_lookup()``) does _not_ try to prevent this
+from happening, but only to detect when it happens.
+``rename_lock`` is a seqlock that is updated whenever any dentry is
+renamed. If ``d_lookup`` finds that a rename happened while it
+unsuccessfully scanned a chain in the hash table, it simply tries
+again.
+
+inode->i_rwsem
+~~~~~~~~~~~~~~
+
+``i_rwsem`` is a read/write semaphore that serializes all changes to a particular
+directory. This ensures that, for example, an ``unlink()`` and a ``rename()``
+cannot both happen at the same time. It also keeps the directory
+stable while the filesystem is asked to look up a name that is not
+currently in the dcache or, optionally, when the list of entries in a
+directory is being retrieved with ``readdir()``.
+
+This has a complementary role to that of ``d_lock``: ``i_rwsem`` on a
+directory protects all of the names in that directory, while ``d_lock``
+on a name protects just one name in a directory. Most changes to the
+dcache hold ``i_rwsem`` on the relevant directory inode and briefly take
+``d_lock`` on one or more the dentries while the change happens. One
+exception is when idle dentries are removed from the dcache due to
+memory pressure. This uses ``d_lock``, but ``i_rwsem`` plays no role.
+
+The semaphore affects pathname lookup in two distinct ways. Firstly it
+prevents changes during lookup of a name in a directory. ``walk_component()`` uses
+``lookup_fast()`` first which, in turn, checks to see if the name is in the cache,
+using only ``d_lock`` locking. If the name isn't found, then ``walk_component()``
+falls back to ``lookup_slow()`` which takes a shared lock on ``i_rwsem``, checks again that
+the name isn't in the cache, and then calls in to the filesystem to get a
+definitive answer. A new dentry will be added to the cache regardless of
+the result.
+
+Secondly, when pathname lookup reaches the final component, it will
+sometimes need to take an exclusive lock on ``i_rwsem`` before performing the last lookup so
+that the required exclusion can be achieved. How path lookup chooses
+to take, or not take, ``i_rwsem`` is one of the
+issues addressed in a subsequent section.
+
+If two threads attempt to look up the same name at the same time - a
+name that is not yet in the dcache - the shared lock on ``i_rwsem`` will
+not prevent them both adding new dentries with the same name. As this
+would result in confusion an extra level of interlocking is used,
+based around a secondary hash table (``in_lookup_hashtable``) and a
+per-dentry flag bit (``DCACHE_PAR_LOOKUP``).
+
+To add a new dentry to the cache while only holding a shared lock on
+``i_rwsem``, a thread must call ``d_alloc_parallel()``. This allocates a
+dentry, stores the required name and parent in it, checks if there
+is already a matching dentry in the primary or secondary hash
+tables, and if not, stores the newly allocated dentry in the secondary
+hash table, with ``DCACHE_PAR_LOOKUP`` set.
+
+If a matching dentry was found in the primary hash table then that is
+returned and the caller can know that it lost a race with some other
+thread adding the entry. If no matching dentry is found in either
+cache, the newly allocated dentry is returned and the caller can
+detect this from the presence of ``DCACHE_PAR_LOOKUP``. In this case it
+knows that it has won any race and now is responsible for asking the
+filesystem to perform the lookup and find the matching inode. When
+the lookup is complete, it must call ``d_lookup_done()`` which clears
+the flag and does some other house keeping, including removing the
+dentry from the secondary hash table - it will normally have been
+added to the primary hash table already. Note that a ``struct
+waitqueue_head`` is passed to ``d_alloc_parallel()``, and
+``d_lookup_done()`` must be called while this ``waitqueue_head`` is still
+in scope.
+
+If a matching dentry is found in the secondary hash table,
+``d_alloc_parallel()`` has a little more work to do. It first waits for
+``DCACHE_PAR_LOOKUP`` to be cleared, using a wait_queue that was passed
+to the instance of ``d_alloc_parallel()`` that won the race and that
+will be woken by the call to ``d_lookup_done()``. It then checks to see
+if the dentry has now been added to the primary hash table. If it
+has, the dentry is returned and the caller just sees that it lost any
+race. If it hasn't been added to the primary hash table, the most
+likely explanation is that some other dentry was added instead using
+``d_splice_alias()``. In any case, ``d_alloc_parallel()`` repeats all the
+look ups from the start and will normally return something from the
+primary hash table.
+
+mnt->mnt_count
+~~~~~~~~~~~~~~
+
+``mnt_count`` is a per-CPU reference counter on "``mount``" structures.
+Per-CPU here means that incrementing the count is cheap as it only
+uses CPU-local memory, but checking if the count is zero is expensive as
+it needs to check with every CPU. Taking a ``mnt_count`` reference
+prevents the mount structure from disappearing as the result of regular
+unmount operations, but does not prevent a "lazy" unmount. So holding
+``mnt_count`` doesn't ensure that the mount remains in the namespace and,
+in particular, doesn't stabilize the link to the mounted-on dentry. It
+does, however, ensure that the ``mount`` data structure remains coherent,
+and it provides a reference to the root dentry of the mounted
+filesystem. So a reference through ``->mnt_count`` provides a stable
+reference to the mounted dentry, but not the mounted-on dentry.
+
+mount_lock
+~~~~~~~~~~
+
+``mount_lock`` is a global seqlock, a bit like ``rename_lock``. It can be used to
+check if any change has been made to any mount points.
+
+While walking down the tree (away from the root) this lock is used when
+crossing a mount point to check that the crossing was safe. That is,
+the value in the seqlock is read, then the code finds the mount that
+is mounted on the current directory, if there is one, and increments
+the ``mnt_count``. Finally the value in ``mount_lock`` is checked against
+the old value. If there is no change, then the crossing was safe. If there
+was a change, the ``mnt_count`` is decremented and the whole process is
+retried.
+
+When walking up the tree (towards the root) by following a ".." link,
+a little more care is needed. In this case the seqlock (which
+contains both a counter and a spinlock) is fully locked to prevent
+any changes to any mount points while stepping up. This locking is
+needed to stabilize the link to the mounted-on dentry, which the
+refcount on the mount itself doesn't ensure.
+
+RCU
+~~~
+
+Finally the global (but extremely lightweight) RCU read lock is held
+from time to time to ensure certain data structures don't get freed
+unexpectedly.
+
+In particular it is held while scanning chains in the dcache hash
+table, and the mount point hash table.
+
+Bringing it together with ``struct nameidata``
+----------------------------------------------
+
+.. _First edition Unix: http://minnie.tuhs.org/cgi-bin/utree.pl?file=V1/u2.s
+
+Throughout the process of walking a path, the current status is stored
+in a ``struct nameidata``, "namei" being the traditional name - dating
+all the way back to `First Edition Unix`_ - of the function that
+converts a "name" to an "inode". ``struct nameidata`` contains (among
+other fields):
+
+``struct path path``
+~~~~~~~~~~~~~~~~~~~~
+
+A ``path`` contains a ``struct vfsmount`` (which is
+embedded in a ``struct mount``) and a ``struct dentry``. Together these
+record the current status of the walk. They start out referring to the
+starting point (the current working directory, the root directory, or some other
+directory identified by a file descriptor), and are updated on each
+step. A reference through ``d_lockref`` and ``mnt_count`` is always
+held.
+
+``struct qstr last``
+~~~~~~~~~~~~~~~~~~~~
+
+This is a string together with a length (i.e. _not_ ``nul`` terminated)
+that is the "next" component in the pathname.
+
+``int last_type``
+~~~~~~~~~~~~~~~~~
+
+This is one of ``LAST_NORM``, ``LAST_ROOT``, ``LAST_DOT``, ``LAST_DOTDOT``, or
+``LAST_BIND``. The ``last`` field is only valid if the type is
+``LAST_NORM``. ``LAST_BIND`` is used when following a symlink and no
+components of the symlink have been processed yet. Others should be
+fairly self-explanatory.
+
+``struct path root``
+~~~~~~~~~~~~~~~~~~~~
+
+This is used to hold a reference to the effective root of the
+filesystem. Often that reference won't be needed, so this field is
+only assigned the first time it is used, or when a non-standard root
+is requested. Keeping a reference in the ``nameidata`` ensures that
+only one root is in effect for the entire path walk, even if it races
+with a ``chroot()`` system call.
+
+The root is needed when either of two conditions holds: (1) either the
+pathname or a symbolic link starts with a "'/'", or (2) a "``..``"
+component is being handled, since "``..``" from the root must always stay
+at the root. The value used is usually the current root directory of
+the calling process. An alternate root can be provided as when
+``sysctl()`` calls ``file_open_root()``, and when NFSv4 or Btrfs call
+``mount_subtree()``. In each case a pathname is being looked up in a very
+specific part of the filesystem, and the lookup must not be allowed to
+escape that subtree. It works a bit like a local ``chroot()``.
+
+Ignoring the handling of symbolic links, we can now describe the
+"``link_path_walk()``" function, which handles the lookup of everything
+except the final component as:
+
+ Given a path (``name``) and a nameidata structure (``nd``), check that the
+ current directory has execute permission and then advance ``name``
+ over one component while updating ``last_type`` and ``last``. If that
+ was the final component, then return, otherwise call
+ ``walk_component()`` and repeat from the top.
+
+``walk_component()`` is even easier. If the component is ``LAST_DOTS``,
+it calls ``handle_dots()`` which does the necessary locking as already
+described. If it finds a ``LAST_NORM`` component it first calls
+"``lookup_fast()``" which only looks in the dcache, but will ask the
+filesystem to revalidate the result if it is that sort of filesystem.
+If that doesn't get a good result, it calls "``lookup_slow()``" which
+takes ``i_rwsem``, rechecks the cache, and then asks the filesystem
+to find a definitive answer. Each of these will call
+``follow_managed()`` (as described below) to handle any mount points.
+
+In the absence of symbolic links, ``walk_component()`` creates a new
+``struct path`` containing a counted reference to the new dentry and a
+reference to the new ``vfsmount`` which is only counted if it is
+different from the previous ``vfsmount``. It then calls
+``path_to_nameidata()`` to install the new ``struct path`` in the
+``struct nameidata`` and drop the unneeded references.
+
+This "hand-over-hand" sequencing of getting a reference to the new
+dentry before dropping the reference to the previous dentry may
+seem obvious, but is worth pointing out so that we will recognize its
+analogue in the "RCU-walk" version.
+
+Handling the final component
+----------------------------
+
+``link_path_walk()`` only walks as far as setting ``nd->last`` and
+``nd->last_type`` to refer to the final component of the path. It does
+not call ``walk_component()`` that last time. Handling that final
+component remains for the caller to sort out. Those callers are
+``path_lookupat()``, ``path_parentat()``, ``path_mountpoint()`` and
+``path_openat()`` each of which handles the differing requirements of
+different system calls.
+
+``path_parentat()`` is clearly the simplest - it just wraps a little bit
+of housekeeping around ``link_path_walk()`` and returns the parent
+directory and final component to the caller. The caller will be either
+aiming to create a name (via ``filename_create()``) or remove or rename
+a name (in which case ``user_path_parent()`` is used). They will use
+``i_rwsem`` to exclude other changes while they validate and then
+perform their operation.
+
+``path_lookupat()`` is nearly as simple - it is used when an existing
+object is wanted such as by ``stat()`` or ``chmod()``. It essentially just
+calls ``walk_component()`` on the final component through a call to
+``lookup_last()``. ``path_lookupat()`` returns just the final dentry.
+
+``path_mountpoint()`` handles the special case of unmounting which must
+not try to revalidate the mounted filesystem. It effectively
+contains, through a call to ``mountpoint_last()``, an alternate
+implementation of ``lookup_slow()`` which skips that step. This is
+important when unmounting a filesystem that is inaccessible, such as
+one provided by a dead NFS server.
+
+Finally ``path_openat()`` is used for the ``open()`` system call; it
+contains, in support functions starting with "``do_last()``", all the
+complexity needed to handle the different subtleties of O_CREAT (with
+or without O_EXCL), final "``/``" characters, and trailing symbolic
+links. We will revisit this in the final part of this series, which
+focuses on those symbolic links. "``do_last()``" will sometimes, but
+not always, take ``i_rwsem``, depending on what it finds.
+
+Each of these, or the functions which call them, need to be alert to
+the possibility that the final component is not ``LAST_NORM``. If the
+goal of the lookup is to create something, then any value for
+``last_type`` other than ``LAST_NORM`` will result in an error. For
+example if ``path_parentat()`` reports ``LAST_DOTDOT``, then the caller
+won't try to create that name. They also check for trailing slashes
+by testing ``last.name[last.len]``. If there is any character beyond
+the final component, it must be a trailing slash.
+
+Revalidation and automounts
+---------------------------
+
+Apart from symbolic links, there are only two parts of the "REF-walk"
+process not yet covered. One is the handling of stale cache entries
+and the other is automounts.
+
+On filesystems that require it, the lookup routines will call the
+``->d_revalidate()`` dentry method to ensure that the cached information
+is current. This will often confirm validity or update a few details
+from a server. In some cases it may find that there has been change
+further up the path and that something that was thought to be valid
+previously isn't really. When this happens the lookup of the whole
+path is aborted and retried with the "``LOOKUP_REVAL``" flag set. This
+forces revalidation to be more thorough. We will see more details of
+this retry process in the next article.
+
+Automount points are locations in the filesystem where an attempt to
+lookup a name can trigger changes to how that lookup should be
+handled, in particular by mounting a filesystem there. These are
+covered in greater detail in autofs.txt in the Linux documentation
+tree, but a few notes specifically related to path lookup are in order
+here.
+
+The Linux VFS has a concept of "managed" dentries which is reflected
+in function names such as "``follow_managed()``". There are three
+potentially interesting things about these dentries corresponding
+to three different flags that might be set in ``dentry->d_flags``:
+
+``DCACHE_MANAGE_TRANSIT``
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If this flag has been set, then the filesystem has requested that the
+``d_manage()`` dentry operation be called before handling any possible
+mount point. This can perform two particular services:
+
+It can block to avoid races. If an automount point is being
+unmounted, the ``d_manage()`` function will usually wait for that
+process to complete before letting the new lookup proceed and possibly
+trigger a new automount.
+
+It can selectively allow only some processes to transit through a
+mount point. When a server process is managing automounts, it may
+need to access a directory without triggering normal automount
+processing. That server process can identify itself to the ``autofs``
+filesystem, which will then give it a special pass through
+``d_manage()`` by returning ``-EISDIR``.
+
+``DCACHE_MOUNTED``
+~~~~~~~~~~~~~~~~~~
+
+This flag is set on every dentry that is mounted on. As Linux
+supports multiple filesystem namespaces, it is possible that the
+dentry may not be mounted on in *this* namespace, just in some
+other. So this flag is seen as a hint, not a promise.
+
+If this flag is set, and ``d_manage()`` didn't return ``-EISDIR``,
+``lookup_mnt()`` is called to examine the mount hash table (honoring the
+``mount_lock`` described earlier) and possibly return a new ``vfsmount``
+and a new ``dentry`` (both with counted references).
+
+``DCACHE_NEED_AUTOMOUNT``
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If ``d_manage()`` allowed us to get this far, and ``lookup_mnt()`` didn't
+find a mount point, then this flag causes the ``d_automount()`` dentry
+operation to be called.
+
+The ``d_automount()`` operation can be arbitrarily complex and may
+communicate with server processes etc. but it should ultimately either
+report that there was an error, that there was nothing to mount, or
+should provide an updated ``struct path`` with new ``dentry`` and ``vfsmount``.
+
+In the latter case, ``finish_automount()`` will be called to safely
+install the new mount point into the mount table.
+
+There is no new locking of import here and it is important that no
+locks (only counted references) are held over this processing due to
+the very real possibility of extended delays.
+This will become more important next time when we examine RCU-walk
+which is particularly sensitive to delays.
+
+RCU-walk - faster pathname lookup in Linux
+==========================================
+
+RCU-walk is another algorithm for performing pathname lookup in Linux.
+It is in many ways similar to REF-walk and the two share quite a bit
+of code. The significant difference in RCU-walk is how it allows for
+the possibility of concurrent access.
+
+We noted that REF-walk is complex because there are numerous details
+and special cases. RCU-walk reduces this complexity by simply
+refusing to handle a number of cases -- it instead falls back to
+REF-walk. The difficulty with RCU-walk comes from a different
+direction: unfamiliarity. The locking rules when depending on RCU are
+quite different from traditional locking, so we will spend a little extra
+time when we come to those.
+
+Clear demarcation of roles
+--------------------------
+
+The easiest way to manage concurrency is to forcibly stop any other
+thread from changing the data structures that a given thread is
+looking at. In cases where no other thread would even think of
+changing the data and lots of different threads want to read at the
+same time, this can be very costly. Even when using locks that permit
+multiple concurrent readers, the simple act of updating the count of
+the number of current readers can impose an unwanted cost. So the
+goal when reading a shared data structure that no other process is
+changing is to avoid writing anything to memory at all. Take no
+locks, increment no counts, leave no footprints.
+
+The REF-walk mechanism already described certainly doesn't follow this
+principle, but then it is really designed to work when there may well
+be other threads modifying the data. RCU-walk, in contrast, is
+designed for the common situation where there are lots of frequent
+readers and only occasional writers. This may not be common in all
+parts of the filesystem tree, but in many parts it will be. For the
+other parts it is important that RCU-walk can quickly fall back to
+using REF-walk.
+
+Pathname lookup always starts in RCU-walk mode but only remains there
+as long as what it is looking for is in the cache and is stable. It
+dances lightly down the cached filesystem image, leaving no footprints
+and carefully watching where it is, to be sure it doesn't trip. If it
+notices that something has changed or is changing, or if something
+isn't in the cache, then it tries to stop gracefully and switch to
+REF-walk.
+
+This stopping requires getting a counted reference on the current
+``vfsmount`` and ``dentry``, and ensuring that these are still valid -
+that a path walk with REF-walk would have found the same entries.
+This is an invariant that RCU-walk must guarantee. It can only make
+decisions, such as selecting the next step, that are decisions which
+REF-walk could also have made if it were walking down the tree at the
+same time. If the graceful stop succeeds, the rest of the path is
+processed with the reliable, if slightly sluggish, REF-walk. If
+RCU-walk finds it cannot stop gracefully, it simply gives up and
+restarts from the top with REF-walk.
+
+This pattern of "try RCU-walk, if that fails try REF-walk" can be
+clearly seen in functions like ``filename_lookup()``,
+``filename_parentat()``, ``filename_mountpoint()``,
+``do_filp_open()``, and ``do_file_open_root()``. These five
+correspond roughly to the four ``path_``* functions we met earlier,
+each of which calls ``link_path_walk()``. The ``path_*`` functions are
+called using different mode flags until a mode is found which works.
+They are first called with ``LOOKUP_RCU`` set to request "RCU-walk". If
+that fails with the error ``ECHILD`` they are called again with no
+special flag to request "REF-walk". If either of those report the
+error ``ESTALE`` a final attempt is made with ``LOOKUP_REVAL`` set (and no
+``LOOKUP_RCU``) to ensure that entries found in the cache are forcibly
+revalidated - normally entries are only revalidated if the filesystem
+determines that they are too old to trust.
+
+The ``LOOKUP_RCU`` attempt may drop that flag internally and switch to
+REF-walk, but will never then try to switch back to RCU-walk. Places
+that trip up RCU-walk are much more likely to be near the leaves and
+so it is very unlikely that there will be much, if any, benefit from
+switching back.
+
+RCU and seqlocks: fast and light
+--------------------------------
+
+RCU is, unsurprisingly, critical to RCU-walk mode. The
+``rcu_read_lock()`` is held for the entire time that RCU-walk is walking
+down a path. The particular guarantee it provides is that the key
+data structures - dentries, inodes, super_blocks, and mounts - will
+not be freed while the lock is held. They might be unlinked or
+invalidated in one way or another, but the memory will not be
+repurposed so values in various fields will still be meaningful. This
+is the only guarantee that RCU provides; everything else is done using
+seqlocks.
+
+As we saw above, REF-walk holds a counted reference to the current
+dentry and the current vfsmount, and does not release those references
+before taking references to the "next" dentry or vfsmount. It also
+sometimes takes the ``d_lock`` spinlock. These references and locks are
+taken to prevent certain changes from happening. RCU-walk must not
+take those references or locks and so cannot prevent such changes.
+Instead, it checks to see if a change has been made, and aborts or
+retries if it has.
+
+To preserve the invariant mentioned above (that RCU-walk may only make
+decisions that REF-walk could have made), it must make the checks at
+or near the same places that REF-walk holds the references. So, when
+REF-walk increments a reference count or takes a spinlock, RCU-walk
+samples the status of a seqlock using ``read_seqcount_begin()`` or a
+similar function. When REF-walk decrements the count or drops the
+lock, RCU-walk checks if the sampled status is still valid using
+``read_seqcount_retry()`` or similar.
+
+However, there is a little bit more to seqlocks than that. If
+RCU-walk accesses two different fields in a seqlock-protected
+structure, or accesses the same field twice, there is no a priori
+guarantee of any consistency between those accesses. When consistency
+is needed - which it usually is - RCU-walk must take a copy and then
+use ``read_seqcount_retry()`` to validate that copy.
+
+``read_seqcount_retry()`` not only checks the sequence number, but also
+imposes a memory barrier so that no memory-read instruction from
+*before* the call can be delayed until *after* the call, either by the
+CPU or by the compiler. A simple example of this can be seen in
+``slow_dentry_cmp()`` which, for filesystems which do not use simple
+byte-wise name equality, calls into the filesystem to compare a name
+against a dentry. The length and name pointer are copied into local
+variables, then ``read_seqcount_retry()`` is called to confirm the two
+are consistent, and only then is ``->d_compare()`` called. When
+standard filename comparison is used, ``dentry_cmp()`` is called
+instead. Notably it does _not_ use ``read_seqcount_retry()``, but
+instead has a large comment explaining why the consistency guarantee
+isn't necessary. A subsequent ``read_seqcount_retry()`` will be
+sufficient to catch any problem that could occur at this point.
+
+With that little refresher on seqlocks out of the way we can look at
+the bigger picture of how RCU-walk uses seqlocks.
+
+``mount_lock`` and ``nd->m_seq``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+We already met the ``mount_lock`` seqlock when REF-walk used it to
+ensure that crossing a mount point is performed safely. RCU-walk uses
+it for that too, but for quite a bit more.
+
+Instead of taking a counted reference to each ``vfsmount`` as it
+descends the tree, RCU-walk samples the state of ``mount_lock`` at the
+start of the walk and stores this initial sequence number in the
+``struct nameidata`` in the ``m_seq`` field. This one lock and one
+sequence number are used to validate all accesses to all ``vfsmounts``,
+and all mount point crossings. As changes to the mount table are
+relatively rare, it is reasonable to fall back on REF-walk any time
+that any "mount" or "unmount" happens.
+
+``m_seq`` is checked (using ``read_seqretry()``) at the end of an RCU-walk
+sequence, whether switching to REF-walk for the rest of the path or
+when the end of the path is reached. It is also checked when stepping
+down over a mount point (in ``__follow_mount_rcu()``) or up (in
+``follow_dotdot_rcu()``). If it is ever found to have changed, the
+whole RCU-walk sequence is aborted and the path is processed again by
+REF-walk.
+
+If RCU-walk finds that ``mount_lock`` hasn't changed then it can be sure
+that, had REF-walk taken counted references on each vfsmount, the
+results would have been the same. This ensures the invariant holds,
+at least for vfsmount structures.
+
+``dentry->d_seq`` and ``nd->seq``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In place of taking a count or lock on ``d_reflock``, RCU-walk samples
+the per-dentry ``d_seq`` seqlock, and stores the sequence number in the
+``seq`` field of the nameidata structure, so ``nd->seq`` should always be
+the current sequence number of ``nd->dentry``. This number needs to be
+revalidated after copying, and before using, the name, parent, or
+inode of the dentry.
+
+The handling of the name we have already looked at, and the parent is
+only accessed in ``follow_dotdot_rcu()`` which fairly trivially follows
+the required pattern, though it does so for three different cases.
+
+When not at a mount point, ``d_parent`` is followed and its ``d_seq`` is
+collected. When we are at a mount point, we instead follow the
+``mnt->mnt_mountpoint`` link to get a new dentry and collect its
+``d_seq``. Then, after finally finding a ``d_parent`` to follow, we must
+check if we have landed on a mount point and, if so, must find that
+mount point and follow the ``mnt->mnt_root`` link. This would imply a
+somewhat unusual, but certainly possible, circumstance where the
+starting point of the path lookup was in part of the filesystem that
+was mounted on, and so not visible from the root.
+
+The inode pointer, stored in ``->d_inode``, is a little more
+interesting. The inode will always need to be accessed at least
+twice, once to determine if it is NULL and once to verify access
+permissions. Symlink handling requires a validated inode pointer too.
+Rather than revalidating on each access, a copy is made on the first
+access and it is stored in the ``inode`` field of ``nameidata`` from where
+it can be safely accessed without further validation.
+
+``lookup_fast()`` is the only lookup routine that is used in RCU-mode,
+``lookup_slow()`` being too slow and requiring locks. It is in
+``lookup_fast()`` that we find the important "hand over hand" tracking
+of the current dentry.
+
+The current ``dentry`` and current ``seq`` number are passed to
+``__d_lookup_rcu()`` which, on success, returns a new ``dentry`` and a
+new ``seq`` number. ``lookup_fast()`` then copies the inode pointer and
+revalidates the new ``seq`` number. It then validates the old ``dentry``
+with the old ``seq`` number one last time and only then continues. This
+process of getting the ``seq`` number of the new dentry and then
+checking the ``seq`` number of the old exactly mirrors the process of
+getting a counted reference to the new dentry before dropping that for
+the old dentry which we saw in REF-walk.
+
+No ``inode->i_rwsem`` or even ``rename_lock``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A semaphore is a fairly heavyweight lock that can only be taken when it is
+permissible to sleep. As ``rcu_read_lock()`` forbids sleeping,
+``inode->i_rwsem`` plays no role in RCU-walk. If some other thread does
+take ``i_rwsem`` and modifies the directory in a way that RCU-walk needs
+to notice, the result will be either that RCU-walk fails to find the
+dentry that it is looking for, or it will find a dentry which
+``read_seqretry()`` won't validate. In either case it will drop down to
+REF-walk mode which can take whatever locks are needed.
+
+Though ``rename_lock`` could be used by RCU-walk as it doesn't require
+any sleeping, RCU-walk doesn't bother. REF-walk uses ``rename_lock`` to
+protect against the possibility of hash chains in the dcache changing
+while they are being searched. This can result in failing to find
+something that actually is there. When RCU-walk fails to find
+something in the dentry cache, whether it is really there or not, it
+already drops down to REF-walk and tries again with appropriate
+locking. This neatly handles all cases, so adding extra checks on
+rename_lock would bring no significant value.
+
+``unlazy walk()`` and ``complete_walk()``
+-----------------------------------------
+
+That "dropping down to REF-walk" typically involves a call to
+``unlazy_walk()``, so named because "RCU-walk" is also sometimes
+referred to as "lazy walk". ``unlazy_walk()`` is called when
+following the path down to the current vfsmount/dentry pair seems to
+have proceeded successfully, but the next step is problematic. This
+can happen if the next name cannot be found in the dcache, if
+permission checking or name revalidation couldn't be achieved while
+the ``rcu_read_lock()`` is held (which forbids sleeping), if an
+automount point is found, or in a couple of cases involving symlinks.
+It is also called from ``complete_walk()`` when the lookup has reached
+the final component, or the very end of the path, depending on which
+particular flavor of lookup is used.
+
+Other reasons for dropping out of RCU-walk that do not trigger a call
+to ``unlazy_walk()`` are when some inconsistency is found that cannot be
+handled immediately, such as ``mount_lock`` or one of the ``d_seq``
+seqlocks reporting a change. In these cases the relevant function
+will return ``-ECHILD`` which will percolate up until it triggers a new
+attempt from the top using REF-walk.
+
+For those cases where ``unlazy_walk()`` is an option, it essentially
+takes a reference on each of the pointers that it holds (vfsmount,
+dentry, and possibly some symbolic links) and then verifies that the
+relevant seqlocks have not been changed. If there have been changes,
+it, too, aborts with ``-ECHILD``, otherwise the transition to REF-walk
+has been a success and the lookup process continues.
+
+Taking a reference on those pointers is not quite as simple as just
+incrementing a counter. That works to take a second reference if you
+already have one (often indirectly through another object), but it
+isn't sufficient if you don't actually have a counted reference at
+all. For ``dentry->d_lockref``, it is safe to increment the reference
+counter to get a reference unless it has been explicitly marked as
+"dead" which involves setting the counter to ``-128``.
+``lockref_get_not_dead()`` achieves this.
+
+For ``mnt->mnt_count`` it is safe to take a reference as long as
+``mount_lock`` is then used to validate the reference. If that
+validation fails, it may *not* be safe to just drop that reference in
+the standard way of calling ``mnt_put()`` - an unmount may have
+progressed too far. So the code in ``legitimize_mnt()``, when it
+finds that the reference it got might not be safe, checks the
+``MNT_SYNC_UMOUNT`` flag to determine if a simple ``mnt_put()`` is
+correct, or if it should just decrement the count and pretend none of
+this ever happened.
+
+Taking care in filesystems
+--------------------------
+
+RCU-walk depends almost entirely on cached information and often will
+not call into the filesystem at all. However there are two places,
+besides the already-mentioned component-name comparison, where the
+file system might be included in RCU-walk, and it must know to be
+careful.
+
+If the filesystem has non-standard permission-checking requirements -
+such as a networked filesystem which may need to check with the server
+- the ``i_op->permission`` interface might be called during RCU-walk.
+In this case an extra "``MAY_NOT_BLOCK``" flag is passed so that it
+knows not to sleep, but to return ``-ECHILD`` if it cannot complete
+promptly. ``i_op->permission`` is given the inode pointer, not the
+dentry, so it doesn't need to worry about further consistency checks.
+However if it accesses any other filesystem data structures, it must
+ensure they are safe to be accessed with only the ``rcu_read_lock()``
+held. This typically means they must be freed using ``kfree_rcu()`` or
+similar.
+
+.. _READ_ONCE: https://lwn.net/Articles/624126/
+
+If the filesystem may need to revalidate dcache entries, then
+``d_op->d_revalidate`` may be called in RCU-walk too. This interface
+*is* passed the dentry but does not have access to the ``inode`` or the
+``seq`` number from the ``nameidata``, so it needs to be extra careful
+when accessing fields in the dentry. This "extra care" typically
+involves using `READ_ONCE() <READ_ONCE_>`_ to access fields, and verifying the
+result is not NULL before using it. This pattern can be seen in
+``nfs_lookup_revalidate()``.
+
+A pair of patterns
+------------------
+
+In various places in the details of REF-walk and RCU-walk, and also in
+the big picture, there are a couple of related patterns that are worth
+being aware of.
+
+The first is "try quickly and check, if that fails try slowly". We
+can see that in the high-level approach of first trying RCU-walk and
+then trying REF-walk, and in places where ``unlazy_walk()`` is used to
+switch to REF-walk for the rest of the path. We also saw it earlier
+in ``dget_parent()`` when following a "``..``" link. It tries a quick way
+to get a reference, then falls back to taking locks if needed.
+
+The second pattern is "try quickly and check, if that fails try
+again - repeatedly". This is seen with the use of ``rename_lock`` and
+``mount_lock`` in REF-walk. RCU-walk doesn't make use of this pattern -
+if anything goes wrong it is much safer to just abort and try a more
+sedate approach.
+
+The emphasis here is "try quickly and check". It should probably be
+"try quickly _and carefully,_ then check". The fact that checking is
+needed is a reminder that the system is dynamic and only a limited
+number of things are safe at all. The most likely cause of errors in
+this whole process is assuming something is safe when in reality it
+isn't. Careful consideration of what exactly guarantees the safety of
+each access is sometimes necessary.
+
+A walk among the symlinks
+=========================
+
+There are several basic issues that we will examine to understand the
+handling of symbolic links: the symlink stack, together with cache
+lifetimes, will help us understand the overall recursive handling of
+symlinks and lead to the special care needed for the final component.
+Then a consideration of access-time updates and summary of the various
+flags controlling lookup will finish the story.
+
+The symlink stack
+-----------------
+
+There are only two sorts of filesystem objects that can usefully
+appear in a path prior to the final component: directories and symlinks.
+Handling directories is quite straightforward: the new directory
+simply becomes the starting point at which to interpret the next
+component on the path. Handling symbolic links requires a bit more
+work.
+
+Conceptually, symbolic links could be handled by editing the path. If
+a component name refers to a symbolic link, then that component is
+replaced by the body of the link and, if that body starts with a '/',
+then all preceding parts of the path are discarded. This is what the
+"``readlink -f``" command does, though it also edits out "``.``" and
+"``..``" components.
+
+Directly editing the path string is not really necessary when looking
+up a path, and discarding early components is pointless as they aren't
+looked at anyway. Keeping track of all remaining components is
+important, but they can of course be kept separately; there is no need
+to concatenate them. As one symlink may easily refer to another,
+which in turn can refer to a third, we may need to keep the remaining
+components of several paths, each to be processed when the preceding
+ones are completed. These path remnants are kept on a stack of
+limited size.
+
+There are two reasons for placing limits on how many symlinks can
+occur in a single path lookup. The most obvious is to avoid loops.
+If a symlink referred to itself either directly or through
+intermediaries, then following the symlink can never complete
+successfully - the error ``ELOOP`` must be returned. Loops can be
+detected without imposing limits, but limits are the simplest solution
+and, given the second reason for restriction, quite sufficient.
+
+.. _outlined recently: http://thread.gmane.org/gmane.linux.kernel/1934390/focus=1934550
+
+The second reason was `outlined recently`_ by Linus:
+
+ Because it's a latency and DoS issue too. We need to react well to
+ true loops, but also to "very deep" non-loops. It's not about memory
+ use, it's about users triggering unreasonable CPU resources.
+
+Linux imposes a limit on the length of any pathname: ``PATH_MAX``, which
+is 4096. There are a number of reasons for this limit; not letting the
+kernel spend too much time on just one path is one of them. With
+symbolic links you can effectively generate much longer paths so some
+sort of limit is needed for the same reason. Linux imposes a limit of
+at most 40 symlinks in any one path lookup. It previously imposed a
+further limit of eight on the maximum depth of recursion, but that was
+raised to 40 when a separate stack was implemented, so there is now
+just the one limit.
+
+The ``nameidata`` structure that we met in an earlier article contains a
+small stack that can be used to store the remaining part of up to two
+symlinks. In many cases this will be sufficient. If it isn't, a
+separate stack is allocated with room for 40 symlinks. Pathname
+lookup will never exceed that stack as, once the 40th symlink is
+detected, an error is returned.
+
+It might seem that the name remnants are all that needs to be stored on
+this stack, but we need a bit more. To see that, we need to move on to
+cache lifetimes.
+
+Storage and lifetime of cached symlinks
+---------------------------------------
+
+Like other filesystem resources, such as inodes and directory
+entries, symlinks are cached by Linux to avoid repeated costly access
+to external storage. It is particularly important for RCU-walk to be
+able to find and temporarily hold onto these cached entries, so that
+it doesn't need to drop down into REF-walk.
+
+.. _object-oriented design pattern: https://lwn.net/Articles/446317/
+
+While each filesystem is free to make its own choice, symlinks are
+typically stored in one of two places. Short symlinks are often
+stored directly in the inode. When a filesystem allocates a ``struct
+inode`` it typically allocates extra space to store private data (a
+common `object-oriented design pattern`_ in the kernel). This will
+sometimes include space for a symlink. The other common location is
+in the page cache, which normally stores the content of files. The
+pathname in a symlink can be seen as the content of that symlink and
+can easily be stored in the page cache just like file content.
+
+When neither of these is suitable, the next most likely scenario is
+that the filesystem will allocate some temporary memory and copy or
+construct the symlink content into that memory whenever it is needed.
+
+When the symlink is stored in the inode, it has the same lifetime as
+the inode which, itself, is protected by RCU or by a counted reference
+on the dentry. This means that the mechanisms that pathname lookup
+uses to access the dcache and icache (inode cache) safely are quite
+sufficient for accessing some cached symlinks safely. In these cases,
+the ``i_link`` pointer in the inode is set to point to wherever the
+symlink is stored and it can be accessed directly whenever needed.
+
+When the symlink is stored in the page cache or elsewhere, the
+situation is not so straightforward. A reference on a dentry or even
+on an inode does not imply any reference on cached pages of that
+inode, and even an ``rcu_read_lock()`` is not sufficient to ensure that
+a page will not disappear. So for these symlinks the pathname lookup
+code needs to ask the filesystem to provide a stable reference and,
+significantly, needs to release that reference when it is finished
+with it.
+
+Taking a reference to a cache page is often possible even in RCU-walk
+mode. It does require making changes to memory, which is best avoided,
+but that isn't necessarily a big cost and it is better than dropping
+out of RCU-walk mode completely. Even filesystems that allocate
+space to copy the symlink into can use ``GFP_ATOMIC`` to often successfully
+allocate memory without the need to drop out of RCU-walk. If a
+filesystem cannot successfully get a reference in RCU-walk mode, it
+must return ``-ECHILD`` and ``unlazy_walk()`` will be called to return to
+REF-walk mode in which the filesystem is allowed to sleep.
+
+The place for all this to happen is the ``i_op->follow_link()`` inode
+method. In the present mainline code this is never actually called in
+RCU-walk mode as the rewrite is not quite complete. It is likely that
+in a future release this method will be passed an ``inode`` pointer when
+called in RCU-walk mode so it both (1) knows to be careful, and (2) has the
+validated pointer. Much like the ``i_op->permission()`` method we
+looked at previously, ``->follow_link()`` would need to be careful that
+all the data structures it references are safe to be accessed while
+holding no counted reference, only the RCU lock. Though getting a
+reference with ``->follow_link()`` is not yet done in RCU-walk mode, the
+code is ready to release the reference when that does happen.
+
+This need to drop the reference to a symlink adds significant
+complexity. It requires a reference to the inode so that the
+``i_op->put_link()`` inode operation can be called. In REF-walk, that
+reference is kept implicitly through a reference to the dentry, so
+keeping the ``struct path`` of the symlink is easiest. For RCU-walk,
+the pointer to the inode is kept separately. To allow switching from
+RCU-walk back to REF-walk in the middle of processing nested symlinks
+we also need the seq number for the dentry so we can confirm that
+switching back was safe.
+
+Finally, when providing a reference to a symlink, the filesystem also
+provides an opaque "cookie" that must be passed to ``->put_link()`` so that it
+knows what to free. This might be the allocated memory area, or a
+pointer to the ``struct page`` in the page cache, or something else
+completely. Only the filesystem knows what it is.
+
+In order for the reference to each symlink to be dropped when the walk completes,
+whether in RCU-walk or REF-walk, the symlink stack needs to contain,
+along with the path remnants:
+
+- the ``struct path`` to provide a reference to the inode in REF-walk
+- the ``struct inode *`` to provide a reference to the inode in RCU-walk
+- the ``seq`` to allow the path to be safely switched from RCU-walk to REF-walk
+- the ``cookie`` that tells ``->put_path()`` what to put.
+
+This means that each entry in the symlink stack needs to hold five
+pointers and an integer instead of just one pointer (the path
+remnant). On a 64-bit system, this is about 40 bytes per entry;
+with 40 entries it adds up to 1600 bytes total, which is less than
+half a page. So it might seem like a lot, but is by no means
+excessive.
+
+Note that, in a given stack frame, the path remnant (``name``) is not
+part of the symlink that the other fields refer to. It is the remnant
+to be followed once that symlink has been fully parsed.
+
+Following the symlink
+---------------------
+
+The main loop in ``link_path_walk()`` iterates seamlessly over all
+components in the path and all of the non-final symlinks. As symlinks
+are processed, the ``name`` pointer is adjusted to point to a new
+symlink, or is restored from the stack, so that much of the loop
+doesn't need to notice. Getting this ``name`` variable on and off the
+stack is very straightforward; pushing and popping the references is
+a little more complex.
+
+When a symlink is found, ``walk_component()`` returns the value ``1``
+(``0`` is returned for any other sort of success, and a negative number
+is, as usual, an error indicator). This causes ``get_link()`` to be
+called; it then gets the link from the filesystem. Providing that
+operation is successful, the old path ``name`` is placed on the stack,
+and the new value is used as the ``name`` for a while. When the end of
+the path is found (i.e. ``*name`` is ``'\0'``) the old ``name`` is restored
+off the stack and path walking continues.
+
+Pushing and popping the reference pointers (inode, cookie, etc.) is more
+complex in part because of the desire to handle tail recursion. When
+the last component of a symlink itself points to a symlink, we
+want to pop the symlink-just-completed off the stack before pushing
+the symlink-just-found to avoid leaving empty path remnants that would
+just get in the way.
+
+It is most convenient to push the new symlink references onto the
+stack in ``walk_component()`` immediately when the symlink is found;
+``walk_component()`` is also the last piece of code that needs to look at the
+old symlink as it walks that last component. So it is quite
+convenient for ``walk_component()`` to release the old symlink and pop
+the references just before pushing the reference information for the
+new symlink. It is guided in this by two flags; ``WALK_GET``, which
+gives it permission to follow a symlink if it finds one, and
+``WALK_PUT``, which tells it to release the current symlink after it has been
+followed. ``WALK_PUT`` is tested first, leading to a call to
+``put_link()``. ``WALK_GET`` is tested subsequently (by
+``should_follow_link()``) leading to a call to ``pick_link()`` which sets
+up the stack frame.
+
+Symlinks with no final component
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A pair of special-case symlinks deserve a little further explanation.
+Both result in a new ``struct path`` (with mount and dentry) being set
+up in the ``nameidata``, and result in ``get_link()`` returning ``NULL``.
+
+The more obvious case is a symlink to "``/``". All symlinks starting
+with "``/``" are detected in ``get_link()`` which resets the ``nameidata``
+to point to the effective filesystem root. If the symlink only
+contains "``/``" then there is nothing more to do, no components at all,
+so ``NULL`` is returned to indicate that the symlink can be released and
+the stack frame discarded.
+
+The other case involves things in ``/proc`` that look like symlinks but
+aren't really::
+
+ $ ls -l /proc/self/fd/1
+ lrwx------ 1 neilb neilb 64 Jun 13 10:19 /proc/self/fd/1 -> /dev/pts/4
+
+Every open file descriptor in any process is represented in ``/proc`` by
+something that looks like a symlink. It is really a reference to the
+target file, not just the name of it. When you ``readlink`` these
+objects you get a name that might refer to the same file - unless it
+has been unlinked or mounted over. When ``walk_component()`` follows
+one of these, the ``->follow_link()`` method in "procfs" doesn't return
+a string name, but instead calls ``nd_jump_link()`` which updates the
+``nameidata`` in place to point to that target. ``->follow_link()`` then
+returns ``NULL``. Again there is no final component and ``get_link()``
+reports this by leaving the ``last_type`` field of ``nameidata`` as
+``LAST_BIND``.
+
+Following the symlink in the final component
+--------------------------------------------
+
+All this leads to ``link_path_walk()`` walking down every component, and
+following all symbolic links it finds, until it reaches the final
+component. This is just returned in the ``last`` field of ``nameidata``.
+For some callers, this is all they need; they want to create that
+``last`` name if it doesn't exist or give an error if it does. Other
+callers will want to follow a symlink if one is found, and possibly
+apply special handling to the last component of that symlink, rather
+than just the last component of the original file name. These callers
+potentially need to call ``link_path_walk()`` again and again on
+successive symlinks until one is found that doesn't point to another
+symlink.
+
+This case is handled by the relevant caller of ``link_path_walk()``, such as
+``path_lookupat()`` using a loop that calls ``link_path_walk()``, and then
+handles the final component. If the final component is a symlink
+that needs to be followed, then ``trailing_symlink()`` is called to set
+things up properly and the loop repeats, calling ``link_path_walk()``
+again. This could loop as many as 40 times if the last component of
+each symlink is another symlink.
+
+The various functions that examine the final component and possibly
+report that it is a symlink are ``lookup_last()``, ``mountpoint_last()``
+and ``do_last()``, each of which use the same convention as
+``walk_component()`` of returning ``1`` if a symlink was found that needs
+to be followed.
+
+Of these, ``do_last()`` is the most interesting as it is used for
+opening a file. Part of ``do_last()`` runs with ``i_rwsem`` held and this
+part is in a separate function: ``lookup_open()``.
+
+Explaining ``do_last()`` completely is beyond the scope of this article,
+but a few highlights should help those interested in exploring the
+code.
+
+1. Rather than just finding the target file, ``do_last()`` needs to open
+ it. If the file was found in the dcache, then ``vfs_open()`` is used for
+ this. If not, then ``lookup_open()`` will either call ``atomic_open()`` (if
+ the filesystem provides it) to combine the final lookup with the open, or
+ will perform the separate ``lookup_real()`` and ``vfs_create()`` steps
+ directly. In the later case the actual "open" of this newly found or
+ created file will be performed by ``vfs_open()``, just as if the name
+ were found in the dcache.
+
+2. ``vfs_open()`` can fail with ``-EOPENSTALE`` if the cached information
+ wasn't quite current enough. Rather than restarting the lookup from
+ the top with ``LOOKUP_REVAL`` set, ``lookup_open()`` is called instead,
+ giving the filesystem a chance to resolve small inconsistencies.
+ If that doesn't work, only then is the lookup restarted from the top.
+
+3. An open with O_CREAT **does** follow a symlink in the final component,
+ unlike other creation system calls (like ``mkdir``). So the sequence::
+
+ ln -s bar /tmp/foo
+ echo hello > /tmp/foo
+
+ will create a file called ``/tmp/bar``. This is not permitted if
+ ``O_EXCL`` is set but otherwise is handled for an O_CREAT open much
+ like for a non-creating open: ``should_follow_link()`` returns ``1``, and
+ so does ``do_last()`` so that ``trailing_symlink()`` gets called and the
+ open process continues on the symlink that was found.
+
+Updating the access time
+------------------------
+
+We previously said of RCU-walk that it would "take no locks, increment
+no counts, leave no footprints." We have since seen that some
+"footprints" can be needed when handling symlinks as a counted
+reference (or even a memory allocation) may be needed. But these
+footprints are best kept to a minimum.
+
+One other place where walking down a symlink can involve leaving
+footprints in a way that doesn't affect directories is in updating access times.
+In Unix (and Linux) every filesystem object has a "last accessed
+time", or "``atime``". Passing through a directory to access a file
+within is not considered to be an access for the purposes of
+``atime``; only listing the contents of a directory can update its ``atime``.
+Symlinks are different it seems. Both reading a symlink (with ``readlink()``)
+and looking up a symlink on the way to some other destination can
+update the atime on that symlink.
+
+.. _clearest statement: http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap04.html#tag_04_08
+
+It is not clear why this is the case; POSIX has little to say on the
+subject. The `clearest statement`_ is that, if a particular implementation
+updates a timestamp in a place not specified by POSIX, this must be
+documented "except that any changes caused by pathname resolution need
+not be documented". This seems to imply that POSIX doesn't really
+care about access-time updates during pathname lookup.
+
+.. _Linux 1.3.87: https://git.kernel.org/cgit/linux/kernel/git/history/history.git/diff/fs/ext2/symlink.c?id=f806c6db77b8eaa6e00dcfb6b567706feae8dbb8
+
+An examination of history shows that prior to `Linux 1.3.87`_, the ext2
+filesystem, at least, didn't update atime when following a link.
+Unfortunately we have no record of why that behavior was changed.
+
+In any case, access time must now be updated and that operation can be
+quite complex. Trying to stay in RCU-walk while doing it is best
+avoided. Fortunately it is often permitted to skip the ``atime``
+update. Because ``atime`` updates cause performance problems in various
+areas, Linux supports the ``relatime`` mount option, which generally
+limits the updates of ``atime`` to once per day on files that aren't
+being changed (and symlinks never change once created). Even without
+``relatime``, many filesystems record ``atime`` with a one-second
+granularity, so only one update per second is required.
+
+It is easy to test if an ``atime`` update is needed while in RCU-walk
+mode and, if it isn't, the update can be skipped and RCU-walk mode
+continues. Only when an ``atime`` update is actually required does the
+path walk drop down to REF-walk. All of this is handled in the
+``get_link()`` function.
+
+A few flags
+-----------
+
+A suitable way to wrap up this tour of pathname walking is to list
+the various flags that can be stored in the ``nameidata`` to guide the
+lookup process. Many of these are only meaningful on the final
+component, others reflect the current state of the pathname lookup.
+And then there is ``LOOKUP_EMPTY``, which doesn't fit conceptually with
+the others. If this is not set, an empty pathname causes an error
+very early on. If it is set, empty pathnames are not considered to be
+an error.
+
+Global state flags
+~~~~~~~~~~~~~~~~~~
+
+We have already met two global state flags: ``LOOKUP_RCU`` and
+``LOOKUP_REVAL``. These select between one of three overall approaches
+to lookup: RCU-walk, REF-walk, and REF-walk with forced revalidation.
+
+``LOOKUP_PARENT`` indicates that the final component hasn't been reached
+yet. This is primarily used to tell the audit subsystem the full
+context of a particular access being audited.
+
+``LOOKUP_ROOT`` indicates that the ``root`` field in the ``nameidata`` was
+provided by the caller, so it shouldn't be released when it is no
+longer needed.
+
+``LOOKUP_JUMPED`` means that the current dentry was chosen not because
+it had the right name but for some other reason. This happens when
+following "``..``", following a symlink to ``/``, crossing a mount point
+or accessing a "``/proc/$PID/fd/$FD``" symlink. In this case the
+filesystem has not been asked to revalidate the name (with
+``d_revalidate()``). In such cases the inode may still need to be
+revalidated, so ``d_op->d_weak_revalidate()`` is called if
+``LOOKUP_JUMPED`` is set when the look completes - which may be at the
+final component or, when creating, unlinking, or renaming, at the penultimate component.
+
+Final-component flags
+~~~~~~~~~~~~~~~~~~~~~
+
+Some of these flags are only set when the final component is being
+considered. Others are only checked for when considering that final
+component.
+
+``LOOKUP_AUTOMOUNT`` ensures that, if the final component is an automount
+point, then the mount is triggered. Some operations would trigger it
+anyway, but operations like ``stat()`` deliberately don't. ``statfs()``
+needs to trigger the mount but otherwise behaves a lot like ``stat()``, so
+it sets ``LOOKUP_AUTOMOUNT``, as does "``quotactl()``" and the handling of
+"``mount --bind``".
+
+``LOOKUP_FOLLOW`` has a similar function to ``LOOKUP_AUTOMOUNT`` but for
+symlinks. Some system calls set or clear it implicitly, while
+others have API flags such as ``AT_SYMLINK_FOLLOW`` and
+``UMOUNT_NOFOLLOW`` to control it. Its effect is similar to
+``WALK_GET`` that we already met, but it is used in a different way.
+
+``LOOKUP_DIRECTORY`` insists that the final component is a directory.
+Various callers set this and it is also set when the final component
+is found to be followed by a slash.
+
+Finally ``LOOKUP_OPEN``, ``LOOKUP_CREATE``, ``LOOKUP_EXCL``, and
+``LOOKUP_RENAME_TARGET`` are not used directly by the VFS but are made
+available to the filesystem and particularly the ``->d_revalidate()``
+method. A filesystem can choose not to bother revalidating too hard
+if it knows that it will be asked to open or create the file soon.
+These flags were previously useful for ``->lookup()`` too but with the
+introduction of ``->atomic_open()`` they are less relevant there.
+
+End of the road
+---------------
+
+Despite its complexity, all this pathname lookup code appears to be
+in good shape - various parts are certainly easier to understand now
+than even a couple of releases ago. But that doesn't mean it is
+"finished". As already mentioned, RCU-walk currently only follows
+symlinks that are stored in the inode so, while it handles many ext4
+symlinks, it doesn't help with NFS, XFS, or Btrfs. That support
+is not likely to be long delayed.

-Using flexible arrays in the kernel
-===================================
-
-:Updated: Last updated for 2.6.32
-:Author: Jonathan Corbet <corbet@lwn.net>
-
-Large contiguous memory allocations can be unreliable in the Linux kernel.
-Kernel programmers will sometimes respond to this problem by allocating
-pages with vmalloc(). This solution not ideal, though. On 32-bit systems,
-memory from vmalloc() must be mapped into a relatively small address space;
-it's easy to run out. On SMP systems, the page table changes required by
-vmalloc() allocations can require expensive cross-processor interrupts on
-all CPUs. And, on all systems, use of space in the vmalloc() range
-increases pressure on the translation lookaside buffer (TLB), reducing the
-performance of the system.
-
-In many cases, the need for memory from vmalloc() can be eliminated by
-piecing together an array from smaller parts; the flexible array library
-exists to make this task easier.
-
-A flexible array holds an arbitrary (within limits) number of fixed-sized
-objects, accessed via an integer index. Sparse arrays are handled
-reasonably well. Only single-page allocations are made, so memory
-allocation failures should be relatively rare. The down sides are that the
-arrays cannot be indexed directly, individual object size cannot exceed the
-system page size, and putting data into a flexible array requires a copy
-operation. It's also worth noting that flexible arrays do no internal
-locking at all; if concurrent access to an array is possible, then the
-caller must arrange for appropriate mutual exclusion.
-
-The creation of a flexible array is done with::
-
- #include <linux/flex_array.h>
-
- struct flex_array *flex_array_alloc(int element_size,
- unsigned int total,
- gfp_t flags);
-
-The individual object size is provided by element_size, while total is the
-maximum number of objects which can be stored in the array. The flags
-argument is passed directly to the internal memory allocation calls. With
-the current code, using flags to ask for high memory is likely to lead to
-notably unpleasant side effects.
-
-It is also possible to define flexible arrays at compile time with::
-
- DEFINE_FLEX_ARRAY(name, element_size, total);
-
-This macro will result in a definition of an array with the given name; the
-element size and total will be checked for validity at compile time.
-
-Storing data into a flexible array is accomplished with a call to::
-
- int flex_array_put(struct flex_array *array, unsigned int element_nr,
- void *src, gfp_t flags);
-
-This call will copy the data from src into the array, in the position
-indicated by element_nr (which must be less than the maximum specified when
-the array was created). If any memory allocations must be performed, flags
-will be used. The return value is zero on success, a negative error code
-otherwise.
-
-There might possibly be a need to store data into a flexible array while
-running in some sort of atomic context; in this situation, sleeping in the
-memory allocator would be a bad thing. That can be avoided by using
-GFP_ATOMIC for the flags value, but, often, there is a better way. The
-trick is to ensure that any needed memory allocations are done before
-entering atomic context, using::
-
- int flex_array_prealloc(struct flex_array *array, unsigned int start,
- unsigned int nr_elements, gfp_t flags);
-
-This function will ensure that memory for the elements indexed in the range
-defined by start and nr_elements has been allocated. Thereafter, a
-flex_array_put() call on an element in that range is guaranteed not to
-block.
-
-Getting data back out of the array is done with::
-
- void *flex_array_get(struct flex_array *fa, unsigned int element_nr);
-
-The return value is a pointer to the data element, or NULL if that
-particular element has never been allocated.
-
-Note that it is possible to get back a valid pointer for an element which
-has never been stored in the array. Memory for array elements is allocated
-one page at a time; a single allocation could provide memory for several
-adjacent elements. Flexible array elements are normally initialized to the
-value FLEX_ARRAY_FREE (defined as 0x6c in <linux/poison.h>), so errors
-involving that number probably result from use of unstored array entries.
-Note that, if array elements are allocated with __GFP_ZERO, they will be
-initialized to zero and this poisoning will not happen.
-
-Individual elements in the array can be cleared with::
-
- int flex_array_clear(struct flex_array *array, unsigned int element_nr);
-
-This function will set the given element to FLEX_ARRAY_FREE and return
-zero. If storage for the indicated element is not allocated for the array,
-flex_array_clear() will return -EINVAL instead. Note that clearing an
-element does not release the storage associated with it; to reduce the
-allocated size of an array, call::
-
- int flex_array_shrink(struct flex_array *array);
-
-The return value will be the number of pages of memory actually freed.
-This function works by scanning the array for pages containing nothing but
-FLEX_ARRAY_FREE bytes, so (1) it can be expensive, and (2) it will not work
-if the array's pages are allocated with __GFP_ZERO.
-
-It is possible to remove all elements of an array with a call to::
-
- void flex_array_free_parts(struct flex_array *array);
-
-This call frees all elements, but leaves the array itself in place.
-Freeing the entire array is done with::
-
- void flex_array_free(struct flex_array *array);
-
-As of this writing, there are no users of flexible arrays in the mainline
-kernel. The functions described here are also not exported to modules;
-that will probably be fixed when somebody comes up with a need for it.

+===================================
+ Arm Framebuffer Compression (AFBC)
+===================================
+
+AFBC is a proprietary lossless image compression protocol and format.
+It provides fine-grained random access and minimizes the amount of
+data transferred between IP blocks.
+
+AFBC can be enabled on drivers which support it via use of the AFBC
+format modifiers defined in drm_fourcc.h. See DRM_FORMAT_MOD_ARM_AFBC(*).
+
+All users of the AFBC modifiers must follow the usage guidelines laid
+out in this document, to ensure compatibility across different AFBC
+producers and consumers.
+
+Components and Ordering
+=======================
+
+AFBC streams can contain several components - where a component
+corresponds to a color channel (i.e. R, G, B, X, A, Y, Cb, Cr).
+The assignment of input/output color channels must be consistent
+between the encoder and the decoder for correct operation, otherwise
+the consumer will interpret the decoded data incorrectly.
+
+Furthermore, when the lossless colorspace transform is used
+(AFBC_FORMAT_MOD_YTR, which should be enabled for RGB buffers for
+maximum compression efficiency), the component order must be:
+
+ * Component 0: R
+ * Component 1: G
+ * Component 2: B
+
+The component ordering is communicated via the fourcc code in the
+fourcc:modifier pair. In general, component '0' is considered to
+reside in the least-significant bits of the corresponding linear
+format. For example, COMP(bits):
+
+ * DRM_FORMAT_ABGR8888
+
+ * Component 0: R(8)
+ * Component 1: G(8)
+ * Component 2: B(8)
+ * Component 3: A(8)
+
+ * DRM_FORMAT_BGR888
+
+ * Component 0: R(8)
+ * Component 1: G(8)
+ * Component 2: B(8)
+
+ * DRM_FORMAT_YUYV
+
+ * Component 0: Y(8)
+ * Component 1: Cb(8, 2x1 subsampled)
+ * Component 2: Cr(8, 2x1 subsampled)
+
+In AFBC, 'X' components are not treated any differently from any other
+component. Therefore, an AFBC buffer with fourcc DRM_FORMAT_XBGR8888
+encodes with 4 components, like so:
+
+ * DRM_FORMAT_XBGR8888
+
+ * Component 0: R(8)
+ * Component 1: G(8)
+ * Component 2: B(8)
+ * Component 3: X(8)
+
+Please note, however, that the inclusion of a "wasted" 'X' channel is
+bad for compression efficiency, and so it's recommended to avoid
+formats containing 'X' bits. If a fourth component is
+required/expected by the encoder/decoder, then it is recommended to
+instead use an equivalent format with alpha, setting all alpha bits to
+'1'. If there is no requirement for a fourth component, then a format
+which doesn't include alpha can be used, e.g. DRM_FORMAT_BGR888.
+
+Number of Planes
+================
+
+Formats which are typically multi-planar in linear layouts (e.g. YUV
+420), can be encoded into one, or multiple, AFBC planes. As with
+component order, the encoder and decoder must agree about the number
+of planes in order to correctly decode the buffer. The fourcc code is
+used to determine the number of encoded planes in an AFBC buffer,
+matching the number of planes for the linear (unmodified) format.
+Within each plane, the component ordering also follows the fourcc
+code:
+
+For example:
+
+ * DRM_FORMAT_YUYV: nplanes = 1
+
+ * Plane 0:
+
+ * Component 0: Y(8)
+ * Component 1: Cb(8, 2x1 subsampled)
+ * Component 2: Cr(8, 2x1 subsampled)
+
+ * DRM_FORMAT_NV12: nplanes = 2
+
+ * Plane 0:
+
+ * Component 0: Y(8)
+
+ * Plane 1:
+
+ * Component 0: Cb(8, 2x1 subsampled)
+ * Component 1: Cr(8, 2x1 subsampled)
+
+Cross-device interoperability
+=============================
+
+For maximum compatibility across devices, the table below defines
+canonical formats for use between AFBC-enabled devices. Formats which
+are listed here must be used exactly as specified when using the AFBC
+modifiers. Formats which are not listed should be avoided.

+drm/amd/display - Display Core (DC)
+===================================
+
+*placeholder - general description of supported platforms, what dc is, etc.*
+
+Because it is partially shared with other operating systems, the Display Core
+Driver is divided in two pieces.
+
+1. **Display Core (DC)** contains the OS-agnostic components. Things like
+ hardware programming and resource management are handled here.
+2. **Display Manager (DM)** contains the OS-dependent components. Hooks to the
+ amdgpu base driver and DRM are implemented here.
+
+It doesn't help that the entire package is frequently referred to as DC. But
+with the context in mind, it should be clear.
+
+When CONFIG_DRM_AMD_DC is enabled, DC will be initialized by default for
+supported ASICs. To force disable, set `amdgpu.dc=0` on kernel command line.
+Likewise, to force enable on unsupported ASICs, set `amdgpu.dc=1`.
+
+To determine if DC is loaded, search dmesg for the following entry:
+
+``Display Core initialized with <version number here>``

-KMS Initialization and Cleanup
-==============================
-
-A KMS device is abstracted and exposed as a set of planes, CRTCs,
-encoders and connectors. KMS drivers must thus create and initialize all
-those objects at load time after initializing mode setting.
-
-CRTCs (:c:type:`struct drm_crtc <drm_crtc>`)
---------------------------------------------
-
-A CRTC is an abstraction representing a part of the chip that contains a
-pointer to a scanout buffer. Therefore, the number of CRTCs available
-determines how many independent scanout buffers can be active at any
-given time. The CRTC structure contains several fields to support this:
-a pointer to some video memory (abstracted as a frame buffer object), a
-display mode, and an (x, y) offset into the video memory to support
-panning or configurations where one piece of video memory spans multiple
-CRTCs.
-
-CRTC Initialization
-~~~~~~~~~~~~~~~~~~~
-
-A KMS device must create and register at least one struct
-:c:type:`struct drm_crtc <drm_crtc>` instance. The instance is
-allocated and zeroed by the driver, possibly as part of a larger
-structure, and registered with a call to :c:func:`drm_crtc_init()`
-with a pointer to CRTC functions.
-
-
-Cleanup
--------
-
-The DRM core manages its objects' lifetime. When an object is not needed
-anymore the core calls its destroy function, which must clean up and
-free every resource allocated for the object. Every
-:c:func:`drm_\*_init()` call must be matched with a corresponding
-:c:func:`drm_\*_cleanup()` call to cleanup CRTCs
-(:c:func:`drm_crtc_cleanup()`), planes
-(:c:func:`drm_plane_cleanup()`), encoders
-(:c:func:`drm_encoder_cleanup()`) and connectors
-(:c:func:`drm_connector_cleanup()`). Furthermore, connectors that
-have been added to sysfs must be removed by a call to
-:c:func:`drm_connector_unregister()` before calling
-:c:func:`drm_connector_cleanup()`.
-
-Connectors state change detection must be cleanup up with a call to
-:c:func:`drm_kms_helper_poll_fini()`.
-

-

-
-In the example above (taken from the i915 driver), a CRTC, connector and
-encoder combination is created. A device-specific i2c bus is also
-created for fetching EDID data and performing monitor detection. Once
-the process is complete, the new connector is registered with sysfs to

+ drm/komeda Arm display driver
+==============================
+
+The drm/komeda driver supports the Arm display processor D71 and later products,
+this document gives a brief overview of driver design: how it works and why
+design it like that.
+
+Overview of D71 like display IPs
+================================
+
+From D71, Arm display IP begins to adopt a flexible and modularized
+architecture. A display pipeline is made up of multiple individual and
+functional pipeline stages called components, and every component has some
+specific capabilities that can give the flowed pipeline pixel data a
+particular processing.
+
+Typical D71 components:
+
+Layer
+-----
+Layer is the first pipeline stage, which prepares the pixel data for the next
+stage. It fetches the pixel from memory, decodes it if it's AFBC, rotates the
+source image, unpacks or converts YUV pixels to the device internal RGB pixels,
+then adjusts the color_space of pixels if needed.
+
+Scaler
+------
+As its name suggests, scaler takes responsibility for scaling, and D71 also
+supports image enhancements by scaler.
+The usage of scaler is very flexible and can be connected to layer output
+for layer scaling, or connected to compositor and scale the whole display
+frame and then feed the output data into wb_layer which will then write it
+into memory.
+
+Compositor (compiz)
+-------------------
+Compositor blends multiple layers or pixel data flows into one single display
+frame. its output frame can be fed into post image processor for showing it on
+the monitor or fed into wb_layer and written to memory at the same time.
+user can also insert a scaler between compositor and wb_layer to down scale
+the display frame first and and then write to memory.
+
+Writeback Layer (wb_layer)
+--------------------------
+Writeback layer does the opposite things of Layer, which connects to compiz
+and writes the composition result to memory.
+
+Post image processor (improc)
+-----------------------------
+Post image processor adjusts frame data like gamma and color space to fit the
+requirements of the monitor.
+
+Timing controller (timing_ctrlr)
+--------------------------------
+Final stage of display pipeline, Timing controller is not for the pixel
+handling, but only for controlling the display timing.
+
+Merger
+------
+D71 scaler mostly only has the half horizontal input/output capabilities
+compared with Layer, like if Layer supports 4K input size, the scaler only can
+support 2K input/output in the same time. To achieve the ful frame scaling, D71
+introduces Layer Split, which splits the whole image to two half parts and feeds
+them to two Layers A and B, and does the scaling independently. After scaling
+the result need to be fed to merger to merge two part images together, and then
+output merged result to compiz.
+
+Splitter
+--------
+Similar to Layer Split, but Splitter is used for writeback, which splits the
+compiz result to two parts and then feed them to two scalers.
+
+Possible D71 Pipeline usage
+===========================
+
+Benefitting from the modularized architecture, D71 pipelines can be easily
+adjusted to fit different usages. And D71 has two pipelines, which support two
+types of working mode:
+
+- Dual display mode
+ Two pipelines work independently and separately to drive two display outputs.
+
+- Single display mode
+ Two pipelines work together to drive only one display output.
+
+ On this mode, pipeline_B doesn't work indenpendently, but outputs its
+ composition result into pipeline_A, and its pixel timing also derived from
+ pipeline_A.timing_ctrlr. The pipeline_B works just like a "slave" of
+ pipeline_A(master)

+
+In the following section we'll see these three sub-pipelines will be handled
+by KMS-plane/wb_conn/crtc respectively.
+
+Komeda Resource abstraction
+===========================
+
+struct komeda_pipeline/component
+--------------------------------
+
+To fully utilize and easily access/configure the HW, the driver side also uses
+a similar architecture: Pipeline/Component to describe the HW features and
+capabilities, and a specific component includes two parts:
+
+- Data flow controlling.
+- Specific component capabilities and features.
+
+So the driver defines a common header struct komeda_component to describe the
+data flow control and all specific components are a subclass of this base
+structure.
+
+.. kernel-doc:: drivers/gpu/drm/arm/display/komeda/komeda_pipeline.h
+ :internal:
+
+Resource discovery and initialization
+=====================================
+
+Pipeline and component are used to describe how to handle the pixel data. We
+still need a @struct komeda_dev to describe the whole view of the device, and
+the control-abilites of device.
+
+We have &komeda_dev, &komeda_pipeline, &komeda_component. Now fill devices with
+pipelines. Since komeda is not for D71 only but also intended for later products,
+of course we’d better share as much as possible between different products. To
+achieve this, split the komeda device into two layers: CORE and CHIP.
+
+- CORE: for common features and capabilities handling.
+- CHIP: for register programing and HW specific feature (limitation) handling.
+
+CORE can access CHIP by three chip function structures:
+
+- struct komeda_dev_funcs
+- struct komeda_pipeline_funcs
+- struct komeda_component_funcs
+
+.. kernel-doc:: drivers/gpu/drm/arm/display/komeda/komeda_dev.h
+ :internal:
+
+Format handling
+===============
+
+.. kernel-doc:: drivers/gpu/drm/arm/display/komeda/komeda_format_caps.h
+ :internal:
+.. kernel-doc:: drivers/gpu/drm/arm/display/komeda/komeda_framebuffer.h
+ :internal:
+
+Attach komeda_dev to DRM-KMS
+============================
+
+Komeda abstracts resources by pipeline/component, but DRM-KMS uses
+crtc/plane/connector. One KMS-obj cannot represent only one single component,
+since the requirements of a single KMS object cannot simply be achieved by a
+single component, usually that needs multiple components to fit the requirement.
+Like set mode, gamma, ctm for KMS all target on CRTC-obj, but komeda needs
+compiz, improc and timing_ctrlr to work together to fit these requirements.
+And a KMS-Plane may require multiple komeda resources: layer/scaler/compiz.
+
+So, one KMS-Obj represents a sub-pipeline of komeda resources.
+
+- Plane: `Layer(input) pipeline`_
+- Wb_connector: `Writeback(output) pipeline`_
+- Crtc: `Display output pipeline`_
+
+So, for komeda, we treat KMS crtc/plane/connector as users of pipeline and
+component, and at any one time a pipeline/component only can be used by one
+user. And pipeline/component will be treated as private object of DRM-KMS; the
+state will be managed by drm_atomic_state as well.
+
+How to map plane to Layer(input) pipeline
+-----------------------------------------
+
+Komeda has multiple Layer input pipelines, see:
+- `Single pipeline data flow`_
+- `Dual pipeline with Slave enabled`_
+
+The easiest way is binding a plane to a fixed Layer pipeline, but consider the
+komeda capabilities:
+
+- Layer Split, See `Layer(input) pipeline`_

+ Layer_Split is quite complicated feature, which splits a big image into two

+Runtime Configuration
+---------------------
+
+We want to be able to reconfigure vkms instance without having to reload the
+module. Use/Test-cases:
+
+- Hotplug/hotremove connectors on the fly (to be able to test DP MST handling of
+ compositors).
+
+- Configure planes/crtcs/connectors (we'd need some code to have more than 1 of
+ them first).
+
+- Change output configuration: Plug/unplug screens, change EDID, allow changing
+ the refresh rate.
+
+The currently proposed solution is to expose vkms configuration through
+configfs. All existing module options should be supported through configfs too.
+
+Add Plane Features
+------------------
+
+There's lots of plane features we could add support for:
+
+- Real overlay planes, not just cursor.
+
+- Full alpha blending on all planes.
+
+- Rotation, scaling.
+
+- Additional buffer formats, especially YUV formats for video like NV12.
+ Low/high bpp RGB formats would also be interesting.
+
+- Async updates (currently only possible on cursor plane using the legacy cursor
+ api).
+
+For all of these, we also want to review the igt test coverage and make sure all
+relevant igt testcases work on vkms.
+
+Writeback support
+-----------------
+
+Currently vkms only computes a CRC for each frame. Once we have additional plane
+features, we could write back the entire composited frame, and expose it as:
+
+- Writeback connector. This is useful for testing compositors if you don't have
+ hardware with writeback support.
+
+- As a v4l device. This is useful for debugging compositors on special vkms
+ configurations, so that developers see what's really going on.
+
+Prime Buffer Sharing
+--------------------
+
+We already have vgem, which is a gem driver for testing rendering, similar to
+how vkms is for testing the modeset side. Adding buffer sharing support to vkms
+allows us to test them together, to test synchronization and lots of other
+features. Also, this allows compositors to test whether they work correctly on
+SoC chips, where the display and rendering is very often split between 2
+drivers.
+
+Output Features
+---------------
+
+- Variable refresh rate/freesync support. This probably needs prime buffer
+ sharing support, so that we can use vgem fences to simulate rendering in
+ testing. Also needs support to specify the EDID.
+
+- Add support for link status, so that compositors can validate their runtime
+ fallbacks when e.g. a Display Port link goes bad.
+
+- All the hotplug handling describe under "Runtime Configuration".
+
+Atomic Check using eBPF
+-----------------------
+
+Atomic drivers have lots of restrictions which are not exposed to userspace in
+any explicit form through e.g. possible property values. Userspace can only
+inquiry about these limits through the atomic IOCTL, possibly using the
+TEST_ONLY flag. Trying to add configurable code for all these limits, to allow
+compositors to be tested against them, would be rather futile exercise. Instead
+we could add support for eBPF to validate any kind of atomic state, and
+implement a library of different restrictions.
+
+This needs a bunch of features (plane compositing, multiple outputs, ...)
+enabled already to make sense.

+Author: Eddie James <eajames@linux.ibm.com>
+
+Description
+-----------
+
+This driver supports hardware monitoring for the On-Chip Controller (OCC)
+embedded on POWER processors. The OCC is a device that collects and aggregates
+sensor data from the processor and the system. The OCC can provide the raw
+sensor data as well as perform thermal and power management on the system.
+
+The P8 version of this driver is a client driver of I2C. It may be probed
+manually if an "ibm,p8-occ-hwmon" compatible device is found under the
+appropriate I2C bus node in the device-tree.
+
+The P9 version of this driver is a client driver of the FSI-based OCC driver.
+It will be probed automatically by the FSI-based OCC driver.
+
+Sysfs entries
+-------------
+
+The following attributes are supported. All attributes are read-only unless
+specified.
+

+should be corrupted and that should be detected properly. That means that the

+There doesn't need to be a device at this address because arbitration lost

+This fault injector will create a Kernel panic once the master under test

+state. Use this to check if your shutdown/reboot/boot code can handle this
+scenario.

+Introduction
+------------
+
+This framework is designed to provide a standard kernel interface to control
+the settings of the interconnects on an SoC. These settings can be throughput,
+latency and priority between multiple interconnected devices or functional
+blocks. This can be controlled dynamically in order to save power or provide
+maximum performance.
+
+The interconnect bus is hardware with configurable parameters, which can be
+set on a data path according to the requests received from various drivers.
+An example of interconnect buses are the interconnects between various
+components or functional blocks in chipsets. There can be multiple interconnects
+on an SoC that can be multi-tiered.
+
+Below is a simplified diagram of a real-world SoC interconnect bus topology.
+

+Terminology
+-----------
+
+Interconnect provider is the software definition of the interconnect hardware.
+The interconnect providers on the above diagram are M NoC, S NoC, C NoC, P NoC
+and Mem NoC.
+
+Interconnect node is the software definition of the interconnect hardware
+port. Each interconnect provider consists of multiple interconnect nodes,
+which are connected to other SoC components including other interconnect
+providers. The point on the diagram where the CPUs connect to the memory is
+called an interconnect node, which belongs to the Mem NoC interconnect provider.
+
+Interconnect endpoints are the first or the last element of the path. Every
+endpoint is a node, but not every node is an endpoint.
+
+Interconnect path is everything between two endpoints including all the nodes
+that have to be traversed to reach from a source to destination node. It may
+include multiple master-slave pairs across several interconnect providers.
+
+Interconnect consumers are the entities which make use of the data paths exposed
+by the providers. The consumers send requests to providers requesting various
+throughput, latency and priority. Usually the consumers are device drivers, that
+send request based on their needs. An example for a consumer is a video decoder
+that supports various formats and image sizes.
+
+Interconnect providers
+----------------------
+
+Interconnect provider is an entity that implements methods to initialize and
+configure interconnect bus hardware. The interconnect provider drivers should
+be registered with the interconnect provider core.
+
+.. kernel-doc:: include/linux/interconnect-provider.h
+
+Interconnect consumers
+----------------------
+
+Interconnect consumers are the clients which use the interconnect APIs to
+get paths between endpoints and set their bandwidth/latency/QoS requirements
+for these interconnect paths.

+================================================================
+ VMCOREINFO
+================================================================
+
+===========
+What is it?
+===========
+
+VMCOREINFO is a special ELF note section. It contains various
+information from the kernel like structure size, page size, symbol
+values, field offsets, etc. These data are packed into an ELF note
+section and used by user-space tools like crash and makedumpfile to
+analyze a kernel's memory layout.
+
+================
+Common variables
+================
+
+init_uts_ns.name.release
+------------------------
+
+The version of the Linux kernel. Used to find the corresponding source
+code from which the kernel has been built. For example, crash uses it to
+find the corresponding vmlinux in order to process vmcore.
+
+PAGE_SIZE
+---------
+
+The size of a page. It is the smallest unit of data used by the memory
+management facilities. It is usually 4096 bytes of size and a page is
+aligned on 4096 bytes. Used for computing page addresses.
+
+init_uts_ns
+-----------
+
+The UTS namespace which is used to isolate two specific elements of the
+system that relate to the uname(2) system call. It is named after the
+data structure used to store information returned by the uname(2) system
+call.
+
+User-space tools can get the kernel name, host name, kernel release
+number, kernel version, architecture name and OS type from it.
+
+node_online_map
+---------------
+
+An array node_states[N_ONLINE] which represents the set of online nodes
+in a system, one bit position per node number. Used to keep track of
+which nodes are in the system and online.
+
+swapper_pg_dir
+-------------
+
+The global page directory pointer of the kernel. Used to translate
+virtual to physical addresses.
+
+_stext
+------
+
+Defines the beginning of the text section. In general, _stext indicates
+the kernel start address. Used to convert a virtual address from the
+direct kernel map to a physical address.
+
+vmap_area_list
+--------------
+
+Stores the virtual area list. makedumpfile gets the vmalloc start value
+from this variable and its value is necessary for vmalloc translation.
+
+mem_map
+-------
+
+Physical addresses are translated to struct pages by treating them as
+an index into the mem_map array. Right-shifting a physical address
+PAGE_SHIFT bits converts it into a page frame number which is an index
+into that mem_map array.
+
+Used to map an address to the corresponding struct page.
+
+contig_page_data
+----------------
+
+Makedumpfile gets the pglist_data structure from this symbol, which is
+used to describe the memory layout.
+
+User-space tools use this to exclude free pages when dumping memory.
+
+mem_section|(mem_section, NR_SECTION_ROOTS)|(mem_section, section_mem_map)
+--------------------------------------------------------------------------
+
+The address of the mem_section array, its length, structure size, and
+the section_mem_map offset.
+
+It exists in the sparse memory mapping model, and it is also somewhat
+similar to the mem_map variable, both of them are used to translate an
+address.
+
+page
+----
+
+The size of a page structure. struct page is an important data structure
+and it is widely used to compute contiguous memory.
+
+pglist_data
+-----------
+
+The size of a pglist_data structure. This value is used to check if the
+pglist_data structure is valid. It is also used for checking the memory
+type.
+
+zone
+----
+
+The size of a zone structure. This value is used to check if the zone
+structure has been found. It is also used for excluding free pages.
+
+free_area
+---------
+
+The size of a free_area structure. It indicates whether the free_area
+structure is valid or not. Useful when excluding free pages.
+
+list_head
+---------
+
+The size of a list_head structure. Used when iterating lists in a
+post-mortem analysis session.
+
+nodemask_t
+----------
+
+The size of a nodemask_t type. Used to compute the number of online
+nodes.
+
+(page, flags|_refcount|mapping|lru|_mapcount|private|compound_dtor|

+On NUMA machines, each NUMA node has a pg_data_t to describe its memory
+layout. On UMA machines there is a single pglist_data which describes the
+whole memory.
+
+These values are used to check the memory type and to compute the
+virtual address for memory map.
+
+(zone, free_area|vm_stat|spanned_pages)
+---------------------------------------
+
+Each node is divided into a number of blocks called zones which
+represent ranges within memory. A zone is described by a structure zone.
+
+User-space tools compute required values based on the offset of these
+variables.
+
+(free_area, free_list)
+----------------------
+
+Offset of the free_list's member. This value is used to compute the number
+of free pages.
+
+Each zone has a free_area structure array called free_area[MAX_ORDER].
+The free_list represents a linked list of free page blocks.
+
+(list_head, next|prev)
+----------------------
+
+Offsets of the list_head's members. list_head is used to define a
+circular linked list. User-space tools need these in order to traverse
+lists.
+
+(vmap_area, va_start|list)
+--------------------------
+
+Offsets of the vmap_area's members. They carry vmalloc-specific
+information. Makedumpfile gets the start address of the vmalloc region
+from this.
+
+(zone.free_area, MAX_ORDER)
+---------------------------
+
+Free areas descriptor. User-space tools use this value to iterate the
+free_area ranges. MAX_ORDER is used by the zone buddy allocator.
+
+log_first_idx
+-------------
+
+Index of the first record stored in the buffer log_buf. Used by
+user-space tools to read the strings in the log_buf.
+
+log_buf

+clear_idx
+---------
+
+The index that the next printk() record to read after the last clear

+_CLEAR, like issued by 'dmesg -c'. Used by user-space tools to dump
+the dmesg log.
+
+log_next_idx
+------------
+
+The index of the next record to store in the buffer log_buf. Used to
+compute the index of the current buffer position.
+
+printk_log
+----------
+
+The size of a structure printk_log. Used to compute the size of
+messages, and extract dmesg log. It encapsulates header information for
+log_buf, such as timestamp, syslog level, etc.
+
+(printk_log, ts_nsec|len|text_len|dict_len)
+-------------------------------------------
+
+It represents field offsets in struct printk_log. User space tools
+parse it and check whether the values of printk_log's members have been
+changed.
+
+(free_area.free_list, MIGRATE_TYPES)
+------------------------------------
+
+The number of migrate types for pages. The free_list is described by the
+array. Used by tools to compute the number of free pages.
+
+NR_FREE_PAGES
+-------------
+
+On linux-2.6.21 or later, the number of free pages is in
+vm_stat[NR_FREE_PAGES]. Used to get the number of free pages.
+
+PG_lru|PG_private|PG_swapcache|PG_swapbacked|PG_slab|PG_hwpoision
+|PG_head_mask|PAGE_BUDDY_MAPCOUNT_VALUE(~PG_buddy)
+|PAGE_OFFLINE_MAPCOUNT_VALUE(~PG_offline)

+Page attributes. These flags are used to filter various unnecessary for
+dumping pages.
+
+HUGETLB_PAGE_DTOR
+-----------------

+The HUGETLB_PAGE_DTOR flag denotes hugetlbfs pages. Makedumpfile
+excludes these pages.
+
+======
+x86_64
+======
+
+phys_base
+---------
+
+Used to convert the virtual address of an exported kernel symbol to its
+corresponding physical address.
+
+init_top_pgt
+------------
+
+Used to walk through the whole page table and convert virtual addresses
+to physical addresses. The init_top_pgt is somewhat similar to
+swapper_pg_dir, but it is only used in x86_64.
+
+pgtable_l5_enabled
+------------------
+
+User-space tools need to know whether the crash kernel was in 5-level
+paging mode.
+
+node_data
+---------
+
+This is a struct pglist_data array and stores all NUMA nodes
+information. Makedumpfile gets the pglist_data structure from it.
+
+(node_data, MAX_NUMNODES)
+-------------------------
+
+The maximum number of nodes in system.
+
+KERNELOFFSET
+------------
+
+The kernel randomization offset. Used to compute the page offset. If
+KASLR is disabled, this value is zero.

+KERNEL_IMAGE_SIZE
+-----------------
+
+Currently unused by Makedumpfile. Used to compute the module virtual
+address by Crash.
+
+sme_mask
+--------
+
+AMD-specific with SME support: it indicates the secure memory encryption
+mask. Makedumpfile tools need to know whether the crash kernel was
+encrypted. If SME is enabled in the first kernel, the crash kernel's
+page table entries (pgd/pud/pmd/pte) contain the memory encryption
+mask. This is used to remove the SME mask and obtain the true physical
+address.
+
+Currently, sme_mask stores the value of the C-bit position. If needed,
+additional SME-relevant info can be placed in that variable.
+
+For example:
+[ misc ][ enc bit ][ other misc SME info ]
+0000_0000_0000_0000_1000_0000_0000_0000_0000_0000_..._0000

+
+======
+x86_32
+======
+
+X86_PAE
+-------
+
+Denotes whether physical address extensions are enabled. It has the cost
+of a higher page table lookup overhead, and also consumes more page
+table space per process. Used to check whether PAE was enabled in the
+crash kernel when converting virtual addresses to physical addresses.
+
+====
+ia64
+====
+
+pgdat_list|(pgdat_list, MAX_NUMNODES)
+-------------------------------------
+
+pg_data_t array storing all NUMA nodes information. MAX_NUMNODES
+indicates the number of the nodes.
+
+node_memblk|(node_memblk, NR_NODE_MEMBLKS)
+------------------------------------------
+
+List of node memory chunks. Filled when parsing the SRAT table to obtain
+information about memory nodes. NR_NODE_MEMBLKS indicates the number of
+node memory chunks.
+
+These values are used to compute the number of nodes the crashed kernel used.
+
+node_memblk_s|(node_memblk_s, start_paddr)|(node_memblk_s, size)
+----------------------------------------------------------------
+
+The size of a struct node_memblk_s and the offsets of the
+node_memblk_s's members. Used to compute the number of nodes.
+
+PGTABLE_3|PGTABLE_4
+-------------------
+
+User-space tools need to know whether the crash kernel was in 3-level or
+4-level paging mode. Used to distinguish the page table.
+
+=====

+
+VA_BITS
+-------
+
+The maximum number of bits for virtual addresses. Used to compute the
+virtual memory ranges.
+
+kimage_voffset
+--------------
+
+The offset between the kernel virtual and physical mappings. Used to
+translate virtual to physical addresses.
+
+PHYS_OFFSET
+-----------
+
+Indicates the physical address of the start of memory. Similar to
+kimage_voffset, which is used to translate virtual to physical
+addresses.
+
+KERNELOFFSET
+------------
+
+The kernel randomization offset. Used to compute the page offset. If
+KASLR is disabled, this value is zero.
+
+====
+arm
+====
+
+ARM_LPAE
+--------
+
+It indicates whether the crash kernel supports large physical address
+extensions. Used to translate virtual to physical addresses.

+
+lowcore_ptr
+----------
+
+An array with a pointer to the lowcore of every CPU. Used to print the
+psw and all registers information.
+
+high_memory
+-----------
+
+Used to get the vmalloc_start address from the high_memory symbol.
+

+
+vmemmap_list
+------------
+
+The vmemmap_list maintains the entire vmemmap physical mapping. Used
+to get vmemmap list count and populated vmemmap regions info. If the
+vmemmap address translation information is stored in the crash kernel,
+it is used to translate vmemmap kernel virtual addresses.
+
+mmu_vmemmap_psize
+-----------------
+
+The size of a page. Used to translate virtual to physical addresses.
+
+mmu_psize_defs
+--------------
+
+Page size definitions, i.e. 4k, 64k, or 16M.
+
+Used to make vtop translations.
+
+vmemmap_backing|(vmemmap_backing, list)|(vmemmap_backing, phys)|
+(vmemmap_backing, virt_addr)
+----------------------------------------------------------------
+
+The vmemmap virtual address space management does not have a traditional
+page table to track which virtual struct pages are backed by a physical
+mapping. The virtual to physical mappings are tracked in a simple linked
+list format.
+
+User-space tools need to know the offset of list, phys and virt_addr
+when computing the count of vmemmap regions.
+
+mmu_psize_def|(mmu_psize_def, shift)
+------------------------------------
+
+The size of a struct mmu_psize_def and the offset of mmu_psize_def's

-Test cases
-==========
-
-What follows is not an exhaustive test suite of every possible livepatch
-pre/post-(un)patch combination, but a selection that demonstrates a few
-important concepts. Each test case uses the kernel modules located in
-the samples/livepatch/ and assumes that no livepatches are loaded at the
-beginning of the test.
-
-
-Test 1
-------
-
-Test a combination of loading a kernel module and a livepatch that
-patches a function in the first module. (Un)load the target module
-before the livepatch module:
-
-- load target module
-- load livepatch
-- disable livepatch
-- unload target module
-- unload livepatch
-
-First load a target module:
-
- % insmod samples/livepatch/livepatch-callbacks-mod.ko
- [ 34.475708] livepatch_callbacks_mod: livepatch_callbacks_mod_init
-
-On livepatch enable, before the livepatch transition starts, pre-patch
-callbacks are executed for vmlinux and livepatch_callbacks_mod (those
-klp_objects currently loaded). After klp_objects are patched according
-to the klp_patch, their post-patch callbacks run and the transition
-completes:
-
- % insmod samples/livepatch/livepatch-callbacks-demo.ko
- [ 36.503719] livepatch: enabling patch 'livepatch_callbacks_demo'
- [ 36.504213] livepatch: 'livepatch_callbacks_demo': initializing patching transition
- [ 36.504238] livepatch_callbacks_demo: pre_patch_callback: vmlinux
- [ 36.504721] livepatch_callbacks_demo: pre_patch_callback: livepatch_callbacks_mod -> [MODULE_STATE_LIVE] Normal state

- [ 37.728792] livepatch: 'livepatch_callbacks_demo': patching complete
-
-Similarly, on livepatch disable, pre-patch callbacks run before the
-unpatching transition starts. klp_objects are reverted, post-patch
-callbacks execute and the transition completes:
-
- % echo 0 > /sys/kernel/livepatch/livepatch_callbacks_demo/enabled

-Test 2
-------
-
-This test is similar to the previous test, but (un)load the livepatch
-module before the target kernel module. This tests the livepatch core's
-module_coming handler:
-
-- load livepatch
-- load target module
-- disable livepatch
-- unload livepatch
-- unload target module
-
-
-On livepatch enable, only pre/post-patch callbacks are executed for
-currently loaded klp_objects, in this case, vmlinux:

-------
-
-Test loading the livepatch after a targeted kernel module, then unload

-
-Test a scenario where a vmlinux pre-patch callback returns a non-zero

-------
-
-A similar test as the previous one, but force the "busy" kernel module
-to do longer work.
-
-The livepatching core will refuse to patch a task that is currently
-executing a to-be-patched function -- the consistency model stalls the
-current patch transition until this safety-check is met. Test a
-scenario where one of a livepatch's target klp_objects sits on such a
-function for a long time. Meanwhile, load and unload other target
-kernel modules while the livepatch transition is in progress.
-
-- load busy target module (30s sleep)
-- load livepatch
-- load target module
-- unload target module
-- disable livepatch
-- unload livepatch
-- unload busy target module

-
-Load the "busy" kernel module, this time make it do 30 seconds worth of

- [ 110.994059] livepatch_callbacks_busymod: busymod_work_func, sleeping 30 seconds ...
-
-Meanwhile, the livepatch is loaded. Notice that the patch transition
-does not complete as the targeted "busy" module is sitting on a
-to-be-patched function:

-
-Load a second target module (this one is an ordinary idle kernel
-module). Note that *no* post-patch callbacks will be executed while the
-livepatch is still in transition:

- [ 115.015315] livepatch_callbacks_mod: livepatch_callbacks_mod_init
-
-Request an unload of the simple kernel module. The patch is still
-transitioning, so its pre-unpatch callbacks are skipped:
-
- % rmmod samples/livepatch/livepatch-callbacks-mod.ko

- [ 117.024533] livepatch_callbacks_demo: post_unpatch_callback: livepatch_callbacks_mod -> [MODULE_STATE_GOING] Going away
-
-Finally the livepatch is disabled. Since none of the patch's
-klp_object's post-patch callbacks executed, the remaining klp_object's
-pre-unpatch callbacks are skipped:

+===================================
+Atomic Replace & Cumulative Patches
+===================================
+
+There might be dependencies between livepatches. If multiple patches need
+to do different changes to the same function(s) then we need to define
+an order in which the patches will be installed. And function implementations
+from any newer livepatch must be done on top of the older ones.
+
+This might become a maintenance nightmare. Especially when more patches
+modified the same function in different ways.
+
+An elegant solution comes with the feature called "Atomic Replace". It allows
+creation of so called "Cumulative Patches". They include all wanted changes
+from all older livepatches and completely replace them in one transition.
+
+Usage
+-----
+
+The atomic replace can be enabled by setting "replace" flag in struct klp_patch,
+for example:
+
+ static struct klp_patch patch = {
+ .mod = THIS_MODULE,
+ .objs = objs,
+ .replace = true,
+ };
+
+All processes are then migrated to use the code only from the new patch.
+Once the transition is finished, all older patches are automatically
+disabled.
+
+Ftrace handlers are transparently removed from functions that are no
+longer modified by the new cumulative patch.
+
+As a result, the livepatch authors might maintain sources only for one
+cumulative patch. It helps to keep the patch consistent while adding or
+removing various fixes or features.
+
+Users could keep only the last patch installed on the system after
+the transition to has finished. It helps to clearly see what code is
+actually in use. Also the livepatch might then be seen as a "normal"
+module that modifies the kernel behavior. The only difference is that
+it can be updated at runtime without breaking its functionality.
+
+
+Features
+--------
+
+The atomic replace allows:
+
+ + Atomically revert some functions in a previous patch while
+ upgrading other functions.
+
+ + Remove eventual performance impact caused by core redirection
+ for functions that are no longer patched.
+
+ + Decrease user confusion about dependencies between livepatches.
+
+
+Limitations:
+------------
+
+ + Once the operation finishes, there is no straightforward way
+ to reverse it and restore the replaced patches atomically.
+
+ A good practice is to set .replace flag in any released livepatch.
+ Then re-adding an older livepatch is equivalent to downgrading
+ to that patch. This is safe as long as the livepatches do _not_ do
+ extra modifications in (un)patching callbacks or in the module_init()
+ or module_exit() functions, see below.
+
+ Also note that the replaced patch can be removed and loaded again
+ only when the transition was not forced.
+
+
+ + Only the (un)patching callbacks from the _new_ cumulative livepatch are
+ executed. Any callbacks from the replaced patches are ignored.
+
+ In other words, the cumulative patch is responsible for doing any actions
+ that are necessary to properly replace any older patch.
+
+ As a result, it might be dangerous to replace newer cumulative patches by
+ older ones. The old livepatches might not provide the necessary callbacks.
+
+ This might be seen as a limitation in some scenarios. But it makes life
+ easier in many others. Only the new cumulative livepatch knows what
+ fixes/features are added/removed and what special actions are necessary
+ for a smooth transition.
+
+ In any case, it would be a nightmare to think about the order of
+ the various callbacks and their interactions if the callbacks from all
+ enabled patches were called.
+
+
+ + There is no special handling of shadow variables. Livepatch authors
+ must create their own rules how to pass them from one cumulative
+ patch to the other. Especially that they should not blindly remove
+ them in module_exit() functions.
+
+ A good practice might be to remove shadow variables in the post-unpatch
+ callback. It is called only when the livepatch is properly disabled.

5. Livepatch life-cycle
=======================
-Livepatching defines four basic operations that define the life cycle of each
-live patch: registration, enabling, disabling and unregistration. There are
-several reasons why it is done this way.
+Livepatching can be described by five basic operations:
+loading, enabling, replacing, disabling, removing.
-First, the patch is applied only when all patched symbols for already
-loaded objects are found. The error handling is much easier if this
-check is done before particular functions get redirected.
+Where the replacing and the disabling operations are mutually
+exclusive. They have the same result for the given patch but
+not for the system.
-Second, it might take some time until the entire system is migrated with
-the hybrid consistency model being used. The patch revert might block
-the livepatch module removal for too long. Therefore it is useful to
-revert the patch using a separate operation that might be called
-explicitly. But it does not make sense to remove all information until
-the livepatch module is really removed.
+5.1. Loading
+------------
-5.1. Registration
------------------
+The only reasonable way is to enable the patch when the livepatch kernel
+module is being loaded. For this, klp_enable_patch() has to be called
+in the module_init() callback. There are two main reasons:
-Each patch first has to be registered using klp_register_patch(). This makes
-the patch known to the livepatch framework. Also it does some preliminary
-computing and checks.
+First, only the module has an easy access to the related struct klp_patch.
-In particular, the patch is added into the list of known patches. The
-addresses of the patched functions are found according to their names.
-The special relocations, mentioned in the section "New functions", are
-applied. The relevant entries are created under
-/sys/kernel/livepatch/<name>. The patch is rejected when any operation
-fails.
+Second, the error code might be used to refuse loading the module when
+the patch cannot get enabled.
5.2. Enabling
-------------
-Registered patches might be enabled either by calling klp_enable_patch() or
-by writing '1' to /sys/kernel/livepatch/<name>/enabled. The system will
-start using the new implementation of the patched functions at this stage.
+The livepatch gets enabled by calling klp_enable_patch() from
+the module_init() callback. The system will start using the new
+implementation of the patched functions at this stage.
-When a patch is enabled, livepatch enters into a transition state where
-tasks are converging to the patched state. This is indicated by a value
-of '1' in /sys/kernel/livepatch/<name>/transition. Once all tasks have
-been patched, the 'transition' value changes to '0'. For more
-information about this process, see the "Consistency model" section.
+First, the addresses of the patched functions are found according to their
+names. The special relocations, mentioned in the section "New functions",
+are applied. The relevant entries are created under
+/sys/kernel/livepatch/<name>. The patch is rejected when any above
+operation fails.
-If an original function is patched for the first time, a function
-specific struct klp_ops is created and an universal ftrace handler is
-registered.
+Second, livepatch enters into a transition state where tasks are converging
+to the patched state. If an original function is patched for the first
+time, a function specific struct klp_ops is created and an universal
+ftrace handler is registered[*]. This stage is indicated by a value of '1'
+in /sys/kernel/livepatch/<name>/transition. For more information about
+this process, see the "Consistency model" section.
-Functions might be patched multiple times. The ftrace handler is registered
-only once for the given function. Further patches just add an entry to the
-list (see field `func_stack`) of the struct klp_ops. The last added
-entry is chosen by the ftrace handler and becomes the active function
-replacement.
+Finally, once all tasks have been patched, the 'transition' value changes

+--------------
+
+Enabled patches might get disabled by writing '0' to
+/sys/kernel/livepatch/<name>/enabled.
+
+First, livepatch enters into a transition state where tasks are converging
+to the unpatched state. The system starts using either the code from
+the previously enabled patch or even the original one. This stage is
+indicated by a value of '1' in /sys/kernel/livepatch/<name>/transition.
+For more information about this process, see the "Consistency model"
+section.
+
+Second, once all tasks have been unpatched, the 'transition' value changes
+to '0'. All the functions (struct klp_func) associated with the to-be-disabled
patch are removed from the corresponding struct klp_ops. The ftrace handler
is unregistered and the struct klp_ops is freed when the func_stack list
becomes empty.
-Patches must be disabled in exactly the reverse order in which they were
-enabled. It makes the problem and the implementation much easier.
-
+Third, the sysfs interface is destroyed.
-5.4. Unregistration
--------------------
-Disabled patches might be unregistered by calling klp_unregister_patch().
-This can be done only when the patch is disabled and the code is no longer
-used. It must be called before the livepatch module gets unloaded.
+5.5. Removing
+-------------
-At this stage, all the relevant sys-fs entries are removed and the patch
-is removed from the list of known patches.
+Module removal is only safe when there are no users of functions provided
+by the module. This is the reason why the force feature permanently
+disables the removal. Only when the system is successfully transitioned
+to a new patch state (patched/unpatched) without being forced it is
+guaranteed that no task sleeps or runs in the old code.

-******************
-Teletext Interface
-******************
-
-This interface was aimed at devices receiving and demodulating Teletext
-data [:ref:`ets300706`, :ref:`itu653`], evaluating the Teletext
-packages and storing formatted pages in cache memory. Such devices are
-usually implemented as microcontrollers with serial interface
-(I:sup:`2`\ C) and could be found on old TV cards, dedicated Teletext
-decoding cards and home-brew devices connected to the PC parallel port.
-
-The Teletext API was designed by Martin Buck. It was defined in the
-kernel header file ``linux/videotext.h``, the specification is available
-from
-`ftp://ftp.gwdg.de/pub/linux/misc/videotext/ <ftp://ftp.gwdg.de/pub/linux/misc/videotext/>`__.
-(Videotext is the name of the German public television Teletext
-service.)
-
-Eventually the Teletext API was integrated into the V4L API with
-character device file names ``/dev/vtx0`` to ``/dev/vtx31``, device
-major number 81, minor numbers 192 to 223.
-
-However, teletext decoders were quickly replaced by more generic VBI
-demodulators and those dedicated teletext decoders no longer exist. For
-many years the vtx devices were still around, even though nobody used
-them. So the decision was made to finally remove support for the
-Teletext API in kernel 2.6.37.
-
-Modern devices all use the :ref:`raw <raw-vbi>` or
-:ref:`sliced` VBI API.

+ The Camera class descriptor. Calling
+ :ref:`VIDIOC_QUERYCTRL` for this control will
+ return a description of this control class.
+
+.. _v4l2-exposure-auto-type:
+
+``V4L2_CID_EXPOSURE_AUTO``
+ (enum)
+
+enum v4l2_exposure_auto_type -
+ Enables automatic adjustments of the exposure time and/or iris
+ aperture. The effect of manual changes of the exposure time or iris
+ aperture while these features are enabled is undefined, drivers
+ should ignore such requests. Possible values are:
+
+
+
+.. flat-table::
+ :header-rows: 0
+ :stub-columns: 0
+
+ * - ``V4L2_EXPOSURE_AUTO``
+ - Automatic exposure time, automatic iris aperture.
+ * - ``V4L2_EXPOSURE_MANUAL``
+ - Manual exposure time, manual iris.
+ * - ``V4L2_EXPOSURE_SHUTTER_PRIORITY``
+ - Manual exposure time, auto iris.
+ * - ``V4L2_EXPOSURE_APERTURE_PRIORITY``
+ - Auto exposure time, manual iris.
+
+
+
+``V4L2_CID_EXPOSURE_ABSOLUTE (integer)``
+ Determines the exposure time of the camera sensor. The exposure time
+ is limited by the frame interval. Drivers should interpret the
+ values as 100 µs units, where the value 1 stands for 1/10000th of a
+ second, 10000 for 1 second and 100000 for 10 seconds.
+
+``V4L2_CID_EXPOSURE_AUTO_PRIORITY (boolean)``
+ When ``V4L2_CID_EXPOSURE_AUTO`` is set to ``AUTO`` or
+ ``APERTURE_PRIORITY``, this control determines if the device may
+ dynamically vary the frame rate. By default this feature is disabled
+ (0) and the frame rate must remain constant.
+
+``V4L2_CID_AUTO_EXPOSURE_BIAS (integer menu)``
+ Determines the automatic exposure compensation, it is effective only
+ when ``V4L2_CID_EXPOSURE_AUTO`` control is set to ``AUTO``,
+ ``SHUTTER_PRIORITY`` or ``APERTURE_PRIORITY``. It is expressed in
+ terms of EV, drivers should interpret the values as 0.001 EV units,
+ where the value 1000 stands for +1 EV.
+
+ Increasing the exposure compensation value is equivalent to
+ decreasing the exposure value (EV) and will increase the amount of
+ light at the image sensor. The camera performs the exposure
+ compensation by adjusting absolute exposure time and/or aperture.
+
+.. _v4l2-exposure-metering:
+
+``V4L2_CID_EXPOSURE_METERING``
+ (enum)
+
+enum v4l2_exposure_metering -
+ Determines how the camera measures the amount of light available for
+ the frame exposure. Possible values are:
+
+.. tabularcolumns:: |p{8.5cm}|p{9.0cm}|
+
+.. flat-table::
+ :header-rows: 0
+ :stub-columns: 0
+
+ * - ``V4L2_EXPOSURE_METERING_AVERAGE``
+ - Use the light information coming from the entire frame and average
+ giving no weighting to any particular portion of the metered area.
+ * - ``V4L2_EXPOSURE_METERING_CENTER_WEIGHTED``
+ - Average the light information coming from the entire frame giving
+ priority to the center of the metered area.
+ * - ``V4L2_EXPOSURE_METERING_SPOT``
+ - Measure only very small area at the center of the frame.
+ * - ``V4L2_EXPOSURE_METERING_MATRIX``
+ - A multi-zone metering. The light intensity is measured in several
+ points of the frame and the results are combined. The algorithm of
+ the zones selection and their significance in calculating the
+ final value is device dependent.
+
+
+
+``V4L2_CID_PAN_RELATIVE (integer)``
+ This control turns the camera horizontally by the specified amount.
+ The unit is undefined. A positive value moves the camera to the
+ right (clockwise when viewed from above), a negative value to the
+ left. A value of zero does not cause motion. This is a write-only
+ control.
+
+``V4L2_CID_TILT_RELATIVE (integer)``
+ This control turns the camera vertically by the specified amount.
+ The unit is undefined. A positive value moves the camera up, a
+ negative value down. A value of zero does not cause motion. This is
+ a write-only control.
+
+``V4L2_CID_PAN_RESET (button)``
+ When this control is set, the camera moves horizontally to the

+
+``V4L2_CID_TILT_RESET (button)``
+ When this control is set, the camera moves vertically to the default
+ position.
+
+``V4L2_CID_PAN_ABSOLUTE (integer)``
+ This control turns the camera horizontally to the specified
+ position. Positive values move the camera to the right (clockwise
+ when viewed from above), negative values to the left. Drivers should
+ interpret the values as arc seconds, with valid values between -180
+ * 3600 and +180 * 3600 inclusive.
+
+``V4L2_CID_TILT_ABSOLUTE (integer)``
+ This control turns the camera vertically to the specified position.
+ Positive values move the camera up, negative values down. Drivers
+ should interpret the values as arc seconds, with valid values
+ between -180 * 3600 and +180 * 3600 inclusive.
+
+``V4L2_CID_FOCUS_ABSOLUTE (integer)``
+ This control sets the focal point of the camera to the specified
+ position. The unit is undefined. Positive values set the focus
+ closer to the camera, negative values towards infinity.
+
+``V4L2_CID_FOCUS_RELATIVE (integer)``
+ This control moves the focal point of the camera by the specified
+ amount. The unit is undefined. Positive values move the focus closer
+ to the camera, negative values towards infinity. This is a
+ write-only control.
+
+``V4L2_CID_FOCUS_AUTO (boolean)``
+ Enables continuous automatic focus adjustments. The effect of manual
+ focus adjustments while this feature is enabled is undefined,
+ drivers should ignore such requests.
+
+``V4L2_CID_AUTO_FOCUS_START (button)``
+ Starts single auto focus process. The effect of setting this control
+ when ``V4L2_CID_FOCUS_AUTO`` is set to ``TRUE`` (1) is undefined,
+ drivers should ignore such requests.
+
+``V4L2_CID_AUTO_FOCUS_STOP (button)``
+ Aborts automatic focusing started with ``V4L2_CID_AUTO_FOCUS_START``
+ control. It is effective only when the continuous autofocus is
+ disabled, that is when ``V4L2_CID_FOCUS_AUTO`` control is set to
+ ``FALSE`` (0).
+
+.. _v4l2-auto-focus-status:
+
+``V4L2_CID_AUTO_FOCUS_STATUS (bitmask)``
+ The automatic focus status. This is a read-only control.
+
+ Setting ``V4L2_LOCK_FOCUS`` lock bit of the ``V4L2_CID_3A_LOCK``
+ control may stop updates of the ``V4L2_CID_AUTO_FOCUS_STATUS``
+ control value.

+
+.. flat-table::
+ :header-rows: 0
+ :stub-columns: 0
+
+ * - ``V4L2_AUTO_FOCUS_RANGE_AUTO``
+ - The camera automatically selects the focus range.
+ * - ``V4L2_AUTO_FOCUS_RANGE_NORMAL``
+ - Normal distance range, limited for best automatic focus
+ performance.
+ * - ``V4L2_AUTO_FOCUS_RANGE_MACRO``
+ - Macro (close-up) auto focus. The camera will use its minimum
+ possible distance for auto focus.
+ * - ``V4L2_AUTO_FOCUS_RANGE_INFINITY``
+ - The lens is set to focus on an object at infinite distance.
+
+
+
+``V4L2_CID_ZOOM_ABSOLUTE (integer)``
+ Specify the objective lens focal length as an absolute value. The
+ zoom unit is driver-specific and its value should be a positive
+ integer.
+
+``V4L2_CID_ZOOM_RELATIVE (integer)``
+ Specify the objective lens focal length relatively to the current
+ value. Positive values move the zoom lens group towards the
+ telephoto direction, negative values towards the wide-angle
+ direction. The zoom unit is driver-specific. This is a write-only
+ control.
+
+``V4L2_CID_ZOOM_CONTINUOUS (integer)``
+ Move the objective lens group at the specified speed until it
+ reaches physical device limits or until an explicit request to stop
+ the movement. A positive value moves the zoom lens group towards the
+ telephoto direction. A value of zero stops the zoom lens group
+ movement. A negative value moves the zoom lens group towards the
+ wide-angle direction. The zoom speed unit is driver-specific.
+
+``V4L2_CID_IRIS_ABSOLUTE (integer)``
+ This control sets the camera's aperture to the specified value. The
+ unit is undefined. Larger values open the iris wider, smaller values
+ close it.
+
+``V4L2_CID_IRIS_RELATIVE (integer)``
+ This control modifies the camera's aperture by the specified amount.
+ The unit is undefined. Positive values open the iris one step
+ further, negative values close it one step further. This is a
+ write-only control.
+
+``V4L2_CID_PRIVACY (boolean)``
+ Prevent video from being acquired by the camera. When this control
+ is set to ``TRUE`` (1), no image can be captured by the camera.
+ Common means to enforce privacy are mechanical obturation of the
+ sensor and firmware image processing, but the device is not
+ restricted to these methods. Devices that implement the privacy
+ control must support read access and may support write access.
+
+``V4L2_CID_BAND_STOP_FILTER (integer)``
+ Switch the band-stop filter of a camera sensor on or off, or specify
+ its strength. Such band-stop filters can be used, for example, to
+ filter out the fluorescent light component.
+
+.. _v4l2-auto-n-preset-white-balance:
+
+``V4L2_CID_AUTO_N_PRESET_WHITE_BALANCE``
+ (enum)
+
+enum v4l2_auto_n_preset_white_balance -
+ Sets white balance to automatic, manual or a preset. The presets
+ determine color temperature of the light as a hint to the camera for
+ white balance adjustments resulting in most accurate color
+ representation. The following white balance presets are listed in
+ order of increasing color temperature.
+
+.. tabularcolumns:: |p{7.0 cm}|p{10.5cm}|

+ - White balance preset for fluorescent lighting. It corresponds
+ approximately to 4000...5000 K color temperature.
+ * - ``V4L2_WHITE_BALANCE_FLUORESCENT_H``
+ - With this setting the camera will compensate for fluorescent H
+ lighting.
+ * - ``V4L2_WHITE_BALANCE_HORIZON``
+ - White balance setting for horizon daylight. It corresponds
+ approximately to 5000 K color temperature.
+ * - ``V4L2_WHITE_BALANCE_DAYLIGHT``
+ - White balance preset for daylight (with clear sky). It corresponds
+ approximately to 5000...6500 K color temperature.
+ * - ``V4L2_WHITE_BALANCE_FLASH``
+ - With this setting the camera will compensate for the flash light.
+ It slightly warms up the colors and corresponds roughly to
+ 5000...5500 K color temperature.
+ * - ``V4L2_WHITE_BALANCE_CLOUDY``
+ - White balance preset for moderately overcast sky. This option
+ corresponds approximately to 6500...8000 K color temperature
+ range.
+ * - ``V4L2_WHITE_BALANCE_SHADE``
+ - White balance preset for shade or heavily overcast sky. It
+ corresponds approximately to 9000...10000 K color temperature.
+
+
+
+.. _v4l2-wide-dynamic-range:
+
+``V4L2_CID_WIDE_DYNAMIC_RANGE (boolean)``
+ Enables or disables the camera's wide dynamic range feature. This
+ feature allows to obtain clear images in situations where intensity
+ of the illumination varies significantly throughout the scene, i.e.
+ there are simultaneously very dark and very bright areas. It is most
+ commonly realized in cameras by combining two subsequent frames with
+ different exposure times. [#f1]_
+
+.. _v4l2-image-stabilization:
+
+``V4L2_CID_IMAGE_STABILIZATION (boolean)``
+ Enables or disables image stabilization.
+
+``V4L2_CID_ISO_SENSITIVITY (integer menu)``
+ Determines ISO equivalent of an image sensor indicating the sensor's
+ sensitivity to light. The numbers are expressed in arithmetic scale,
+ as per :ref:`iso12232` standard, where doubling the sensor
+ sensitivity is represented by doubling the numerical ISO value.
+ Applications should interpret the values as standard ISO values
+ multiplied by 1000, e.g. control value 800 stands for ISO 0.8.
+ Drivers will usually support only a subset of standard ISO values.
+ The effect of setting this control while the
+ ``V4L2_CID_ISO_SENSITIVITY_AUTO`` control is set to a value other
+ than ``V4L2_CID_ISO_SENSITIVITY_MANUAL`` is undefined, drivers
+ should ignore such requests.
+
+.. _v4l2-iso-sensitivity-auto-type:

+ * - ``V4L2_CID_ISO_SENSITIVITY_AUTO``
+ - Automatic ISO sensitivity adjustments.
+
+
+
+.. _v4l2-scene-mode:
+
+``V4L2_CID_SCENE_MODE``
+ (enum)
+
+enum v4l2_scene_mode -
+ This control allows to select scene programs as the camera automatic
+ modes optimized for common shooting scenes. Within these modes the
+ camera determines best exposure, aperture, focusing, light metering,
+ white balance and equivalent sensitivity. The controls of those
+ parameters are influenced by the scene mode control. An exact
+ behavior in each mode is subject to the camera specification.
+
+ When the scene mode feature is not used, this control should be set
+ to ``V4L2_SCENE_MODE_NONE`` to make sure the other possibly related
+ controls are accessible. The following scene programs are defined:
+
+.. tabularcolumns:: |p{6.0cm}|p{11.5cm}|
+
+.. flat-table::
+ :header-rows: 0
+ :stub-columns: 0
+
+ * - ``V4L2_SCENE_MODE_NONE``
+ - The scene mode feature is disabled.
+ * - ``V4L2_SCENE_MODE_BACKLIGHT``
+ - Backlight. Compensates for dark shadows when light is coming from
+ behind a subject, also by automatically turning on the flash.
+ * - ``V4L2_SCENE_MODE_BEACH_SNOW``
+ - Beach and snow. This mode compensates for all-white or bright
+ scenes, which tend to look gray and low contrast, when camera's
+ automatic exposure is based on an average scene brightness. To
+ compensate, this mode automatically slightly overexposes the
+ frames. The white balance may also be adjusted to compensate for
+ the fact that reflected snow looks bluish rather than white.
+ * - ``V4L2_SCENE_MODE_CANDLELIGHT``
+ - Candle light. The camera generally raises the ISO sensitivity and
+ lowers the shutter speed. This mode compensates for relatively
+ close subject in the scene. The flash is disabled in order to
+ preserve the ambiance of the light.
+ * - ``V4L2_SCENE_MODE_DAWN_DUSK``
+ - Dawn and dusk. Preserves the colors seen in low natural light
+ before dusk and after down. The camera may turn off the flash, and
+ automatically focus at infinity. It will usually boost saturation
+ and lower the shutter speed.
+ * - ``V4L2_SCENE_MODE_FALL_COLORS``
+ - Fall colors. Increases saturation and adjusts white balance for
+ color enhancement. Pictures of autumn leaves get saturated reds
+ and yellows.
+ * - ``V4L2_SCENE_MODE_FIREWORKS``
+ - Fireworks. Long exposure times are used to capture the expanding
+ burst of light from a firework. The camera may invoke image
+ stabilization.
+ * - ``V4L2_SCENE_MODE_LANDSCAPE``
+ - Landscape. The camera may choose a small aperture to provide deep
+ depth of field and long exposure duration to help capture detail
+ in dim light conditions. The focus is fixed at infinity. Suitable
+ for distant and wide scenery.
+ * - ``V4L2_SCENE_MODE_NIGHT``
+ - Night, also known as Night Landscape. Designed for low light
+ conditions, it preserves detail in the dark areas without blowing
+ out bright objects. The camera generally sets itself to a
+ medium-to-high ISO sensitivity, with a relatively long exposure
+ time, and turns flash off. As such, there will be increased image
+ noise and the possibility of blurred image.
+ * - ``V4L2_SCENE_MODE_PARTY_INDOOR``
+ - Party and indoor. Designed to capture indoor scenes that are lit
+ by indoor background lighting as well as the flash. The camera
+ usually increases ISO sensitivity, and adjusts exposure for the
+ low light conditions.
+ * - ``V4L2_SCENE_MODE_PORTRAIT``
+ - Portrait. The camera adjusts the aperture so that the depth of
+ field is reduced, which helps to isolate the subject against a
+ smooth background. Most cameras recognize the presence of faces in
+ the scene and focus on them. The color hue is adjusted to enhance
+ skin tones. The intensity of the flash is often reduced.
+ * - ``V4L2_SCENE_MODE_SPORTS``
+ - Sports. Significantly increases ISO and uses a fast shutter speed
+ to freeze motion of rapidly-moving subjects. Increased image noise
+ may be seen in this mode.
+ * - ``V4L2_SCENE_MODE_SUNSET``
+ - Sunset. Preserves deep hues seen in sunsets and sunrises. It bumps
+ up the saturation.
+ * - ``V4L2_SCENE_MODE_TEXT``
+ - Text. It applies extra contrast and sharpness, it is typically a
+ black-and-white mode optimized for readability. Automatic focus
+ may be switched to close-up mode and this setting may also involve
+ some lens-distortion correction.
+
+
+
+``V4L2_CID_3A_LOCK (bitmask)``
+ This control locks or unlocks the automatic focus, exposure and
+ white balance. The automatic adjustments can be paused independently
+ by setting the corresponding lock bit to 1. The camera then retains
+ the settings until the lock bit is cleared. The following lock bits
+ are defined:
+
+ When a given algorithm is not enabled, drivers should ignore
+ requests to lock it and should return no error. An example might be
+ an application setting bit ``V4L2_LOCK_WHITE_BALANCE`` when the
+ ``V4L2_CID_AUTO_WHITE_BALANCE`` control is set to ``FALSE``. The
+ value of this control may be changed by exposure, white balance or
+ focus controls.

+ - Automatic white balance adjustments lock.
+ * - ``V4L2_LOCK_FOCUS``
+ - Automatic focus lock.
+
+
+
+``V4L2_CID_PAN_SPEED (integer)``
+ This control turns the camera horizontally at the specific speed.
+ The unit is undefined. A positive value moves the camera to the
+ right (clockwise when viewed from above), a negative value to the
+ left. A value of zero stops the motion if one is in progress and has
+ no effect otherwise.
+
+``V4L2_CID_TILT_SPEED (integer)``
+ This control turns the camera vertically at the specified speed. The
+ unit is undefined. A positive value moves the camera up, a negative
+ value down. A value of zero stops the motion if one is in progress
+ and has no effect otherwise.
+
+.. [#f1]
+ This control may be changed to a menu control in the future, if more
+ options are required.

+Codec Control Reference
+***********************

+Below all controls within the Codec control class are described. First
+the generic controls, then controls specific for certain hardware.
+
+.. note::
+
+ These controls are applicable to all codecs and not just MPEG. The
+ defines are prefixed with V4L2_CID_MPEG/V4L2_MPEG as the controls
+ were originally made for MPEG codecs and later extended to cover all

+*******************************
+Digital Video Control Reference
+*******************************
+
+The Digital Video control class is intended to control receivers and
+transmitters for `VGA <http://en.wikipedia.org/wiki/Vga>`__,
+`DVI <http://en.wikipedia.org/wiki/Digital_Visual_Interface>`__
+(Digital Visual Interface), HDMI (:ref:`hdmi`) and DisplayPort
+(:ref:`dp`). These controls are generally expected to be private to
+the receiver or transmitter subdevice that implements them, so they are
+only exposed on the ``/dev/v4l-subdev*`` device node.
+
+.. note::
+
+ Note that these devices can have multiple input or output pads which are
+ hooked up to e.g. HDMI connectors. Even though the subdevice will
+ receive or transmit video from/to only one of those pads, the other pads
+ can still be active when it comes to EDID (Extended Display
+ Identification Data, :ref:`vesaedid`) and HDCP (High-bandwidth Digital
+ Content Protection System, :ref:`hdcp`) processing, allowing the
+ device to do the fairly slow EDID/HDCP handling in advance. This allows
+ for quick switching between connectors.
+
+These pads appear in several of the controls in this section as
+bitmasks, one bit for each pad. Bit 0 corresponds to pad 0, bit 1 to pad
+1, etc. The maximum value of the control is the set of valid pads.
+
+
+.. _dv-control-id:
+
+Digital Video Control IDs
+=========================
+
+``V4L2_CID_DV_CLASS (class)``
+ The Digital Video class descriptor.
+
+``V4L2_CID_DV_TX_HOTPLUG (bitmask)``
+ Many connectors have a hotplug pin which is high if EDID information
+ is available from the source. This control shows the state of the
+ hotplug pin as seen by the transmitter. Each bit corresponds to an
+ output pad on the transmitter. If an output pad does not have an
+ associated hotplug pin, then the bit for that pad will be 0. This
+ read-only control is applicable to DVI-D, HDMI and DisplayPort
+ connectors.
+
+``V4L2_CID_DV_TX_RXSENSE (bitmask)``
+ Rx Sense is the detection of pull-ups on the TMDS clock lines. This
+ normally means that the sink has left/entered standby (i.e. the
+ transmitter can sense that the receiver is ready to receive video).
+ Each bit corresponds to an output pad on the transmitter. If an
+ output pad does not have an associated Rx Sense, then the bit for
+ that pad will be 0. This read-only control is applicable to DVI-D
+ and HDMI devices.
+
+``V4L2_CID_DV_TX_EDID_PRESENT (bitmask)``
+ When the transmitter sees the hotplug signal from the receiver it
+ will attempt to read the EDID. If set, then the transmitter has read
+ at least the first block (= 128 bytes). Each bit corresponds to an
+ output pad on the transmitter. If an output pad does not support
+ EDIDs, then the bit for that pad will be 0. This read-only control
+ is applicable to VGA, DVI-A/D, HDMI and DisplayPort connectors.
+
+``V4L2_CID_DV_TX_MODE``
+ (enum)
+
+enum v4l2_dv_tx_mode -
+ HDMI transmitters can transmit in DVI-D mode (just video) or in HDMI
+ mode (video + audio + auxiliary data). This control selects which
+ mode to use: V4L2_DV_TX_MODE_DVI_D or V4L2_DV_TX_MODE_HDMI.
+ This control is applicable to HDMI connectors.
+
+``V4L2_CID_DV_TX_RGB_RANGE``
+ (enum)
+
+enum v4l2_dv_rgb_range -
+ Select the quantization range for RGB output. V4L2_DV_RANGE_AUTO
+ follows the RGB quantization range specified in the standard for the
+ video interface (ie. :ref:`cea861` for HDMI).
+ V4L2_DV_RANGE_LIMITED and V4L2_DV_RANGE_FULL override the
+ standard to be compatible with sinks that have not implemented the
+ standard correctly (unfortunately quite common for HDMI and DVI-D).
+ Full range allows all possible values to be used whereas limited
+ range sets the range to (16 << (N-8)) - (235 << (N-8)) where N is
+ the number of bits per component. This control is applicable to VGA,
+ DVI-A/D, HDMI and DisplayPort connectors.
+
+``V4L2_CID_DV_TX_IT_CONTENT_TYPE``
+ (enum)
+
+enum v4l2_dv_it_content_type -
+ Configures the IT Content Type of the transmitted video. This
+ information is sent over HDMI and DisplayPort connectors as part of
+ the AVI InfoFrame. The term 'IT Content' is used for content that
+ originates from a computer as opposed to content from a TV broadcast
+ or an analog source. The enum v4l2_dv_it_content_type defines
+ the possible content types:
+
+.. tabularcolumns:: |p{7.0cm}|p{10.5cm}|
+
+.. flat-table::
+ :header-rows: 0

+
+ * - ``V4L2_DV_IT_CONTENT_TYPE_GRAPHICS``
+ - Graphics content. Pixel data should be passed unfiltered and
+ without analog reconstruction.
+ * - ``V4L2_DV_IT_CONTENT_TYPE_PHOTO``
+ - Photo content. The content is derived from digital still pictures.
+ The content should be passed through with minimal scaling and
+ picture enhancements.
+ * - ``V4L2_DV_IT_CONTENT_TYPE_CINEMA``
+ - Cinema content.
+ * - ``V4L2_DV_IT_CONTENT_TYPE_GAME``
+ - Game content. Audio and video latency should be minimized.
+ * - ``V4L2_DV_IT_CONTENT_TYPE_NO_ITC``
+ - No IT Content information is available and the ITC bit in the AVI
+ InfoFrame is set to 0.
+
+
+
+``V4L2_CID_DV_RX_POWER_PRESENT (bitmask)``
+ Detects whether the receiver receives power from the source (e.g.
+ HDMI carries 5V on one of the pins). This is often used to power an
+ eeprom which contains EDID information, such that the source can
+ read the EDID even if the sink is in standby/power off. Each bit
+ corresponds to an input pad on the receiver. If an input pad
+ cannot detect whether power is present, then the bit for that pad
+ will be 0. This read-only control is applicable to DVI-D, HDMI and
+ DisplayPort connectors.
+
+``V4L2_CID_DV_RX_RGB_RANGE``
+ (enum)
+
+enum v4l2_dv_rgb_range -
+ Select the quantization range for RGB input. V4L2_DV_RANGE_AUTO

+Flash Control Reference
+***********************
+
+The V4L2 flash controls are intended to provide generic access to flash
+controller devices. Flash controller devices are typically used in
+digital cameras.
+
+The interface can support both LED and xenon flash devices. As of
+writing this, there is no xenon flash driver using this interface.
+
+
+.. _flash-controls-use-cases:
+
+Supported use cases
+===================
+
+
+Unsynchronised LED flash (software strobe)
+------------------------------------------
+
+Unsynchronised LED flash is controlled directly by the host as the
+sensor. The flash must be enabled by the host before the exposure of the
+image starts and disabled once it ends. The host is fully responsible
+for the timing of the flash.
+
+Example of such device: Nokia N900.
+
+
+Synchronised LED flash (hardware strobe)
+----------------------------------------
+
+The synchronised LED flash is pre-programmed by the host (power and
+timeout) but controlled by the sensor through a strobe signal from the
+sensor to the flash.
+
+The sensor controls the flash duration and timing. This information
+typically must be made available to the sensor.
+
+
+LED flash as torch
+------------------
+
+LED flash may be used as torch in conjunction with another use case
+involving camera or individually.
+
+
+.. _flash-control-id:
+
+Flash Control IDs
+-----------------
+
+``V4L2_CID_FLASH_CLASS (class)``
+ The FLASH class descriptor.
+
+``V4L2_CID_FLASH_LED_MODE (menu)``
+ Defines the mode of the flash LED, the high-power white LED attached
+ to the flash controller. Setting this control may not be possible in
+ presence of some faults. See V4L2_CID_FLASH_FAULT.
+
+
+
+.. flat-table::
+ :header-rows: 0
+ :stub-columns: 0
+
+ * - ``V4L2_FLASH_LED_MODE_NONE``
+ - Off.
+ * - ``V4L2_FLASH_LED_MODE_FLASH``
+ - Flash mode.
+ * - ``V4L2_FLASH_LED_MODE_TORCH``
+ - Torch mode. See V4L2_CID_FLASH_TORCH_INTENSITY.
+
+
+
+``V4L2_CID_FLASH_STROBE_SOURCE (menu)``
+ Defines the source of the flash LED strobe.
+
+.. tabularcolumns:: |p{7.0cm}|p{10.5cm}|
+
+.. flat-table::
+ :header-rows: 0
+ :stub-columns: 0
+
+ * - ``V4L2_FLASH_STROBE_SOURCE_SOFTWARE``
+ - The flash strobe is triggered by using the
+ V4L2_CID_FLASH_STROBE control.
+ * - ``V4L2_FLASH_STROBE_SOURCE_EXTERNAL``
+ - The flash strobe is triggered by an external source. Typically
+ this is a sensor, which makes it possible to synchronises the
+ flash strobe start to exposure start.
+
+
+
+``V4L2_CID_FLASH_STROBE (button)``
+ Strobe flash. Valid when V4L2_CID_FLASH_LED_MODE is set to
+ V4L2_FLASH_LED_MODE_FLASH and V4L2_CID_FLASH_STROBE_SOURCE
+ is set to V4L2_FLASH_STROBE_SOURCE_SOFTWARE. Setting this
+ control may not be possible in presence of some faults. See
+ V4L2_CID_FLASH_FAULT.
+
+``V4L2_CID_FLASH_STROBE_STOP (button)``
+ Stop flash strobe immediately.
+
+``V4L2_CID_FLASH_STROBE_STATUS (boolean)``
+ Strobe status: whether the flash is strobing at the moment or not.
+ This is a read-only control.
+
+``V4L2_CID_FLASH_TIMEOUT (integer)``
+ Hardware timeout for flash. The flash strobe is stopped after this
+ period of time has passed from the start of the strobe.
+
+``V4L2_CID_FLASH_INTENSITY (integer)``
+ Intensity of the flash strobe when the flash LED is in flash mode
+ (V4L2_FLASH_LED_MODE_FLASH). The unit should be milliamps (mA)
+ if possible.
+
+``V4L2_CID_FLASH_TORCH_INTENSITY (integer)``
+ Intensity of the flash LED in torch mode
+ (V4L2_FLASH_LED_MODE_TORCH). The unit should be milliamps (mA)
+ if possible. Setting this control may not be possible in presence of
+ some faults. See V4L2_CID_FLASH_FAULT.
+
+``V4L2_CID_FLASH_INDICATOR_INTENSITY (integer)``
+ Intensity of the indicator LED. The indicator LED may be fully
+ independent of the flash LED. The unit should be microamps (uA) if
+ possible.
+
+``V4L2_CID_FLASH_FAULT (bitmask)``
+ Faults related to the flash. The faults tell about specific problems
+ in the flash chip itself or the LEDs attached to it. Faults may
+ prevent further use of some of the flash controls. In particular,
+ V4L2_CID_FLASH_LED_MODE is set to V4L2_FLASH_LED_MODE_NONE
+ if the fault affects the flash LED. Exactly which faults have such
+ an effect is chip dependent. Reading the faults resets the control
+ and returns the chip to a usable state if possible.
+
+.. tabularcolumns:: |p{8.0cm}|p{9.5cm}|
+
+.. flat-table::
+ :header-rows: 0
+ :stub-columns: 0
+
+ * - ``V4L2_FLASH_FAULT_OVER_VOLTAGE``
+ - Flash controller voltage to the flash LED has exceeded the limit
+ specific to the flash controller.
+ * - ``V4L2_FLASH_FAULT_TIMEOUT``
+ - The flash strobe was still on when the timeout set by the user ---
+ V4L2_CID_FLASH_TIMEOUT control --- has expired. Not all flash
+ controllers may set this in all such conditions.
+ * - ``V4L2_FLASH_FAULT_OVER_TEMPERATURE``
+ - The flash controller has overheated.
+ * - ``V4L2_FLASH_FAULT_SHORT_CIRCUIT``
+ - The short circuit protection of the flash controller has been
+ triggered.
+ * - ``V4L2_FLASH_FAULT_OVER_CURRENT``
+ - Current in the LED power supply has exceeded the limit specific to
+ the flash controller.
+ * - ``V4L2_FLASH_FAULT_INDICATOR``
+ - The flash controller has detected a short or open circuit
+ condition on the indicator LED.
+ * - ``V4L2_FLASH_FAULT_UNDER_VOLTAGE``
+ - Flash controller voltage to the flash LED has been below the
+ minimum limit specific to the flash controller.
+ * - ``V4L2_FLASH_FAULT_INPUT_VOLTAGE``
+ - The input voltage of the flash controller is below the limit under
+ which strobing the flash at full current will not be possible.The
+ condition persists until this flag is no longer set.
+ * - ``V4L2_FLASH_FAULT_LED_OVER_TEMPERATURE``
+ - The temperature of the LED has exceeded its allowed upper limit.
+
+
+
+``V4L2_CID_FLASH_CHARGE (boolean)``
+ Enable or disable charging of the xenon flash capacitor.
+
+``V4L2_CID_FLASH_READY (boolean)``
+ Is the flash ready to strobe? Xenon flashes require their capacitors
+ charged before strobing. LED flashes often require a cooldown period
+ after strobe during which another strobe will not be possible. This
+ is a read-only control.

+
+``V4L2_CID_IMAGE_PROC_CLASS (class)``
+ The IMAGE_PROC class descriptor.
+
+``V4L2_CID_LINK_FREQ (integer menu)``
+ Data bus frequency. Together with the media bus pixel code, bus type
+ (clock cycles per sample), the data bus frequency defines the pixel
+ rate (``V4L2_CID_PIXEL_RATE``) in the pixel array (or possibly
+ elsewhere, if the device is not an image sensor). The frame rate can
+ be calculated from the pixel clock, image width and height and
+ horizontal and vertical blanking. While the pixel rate control may
+ be defined elsewhere than in the subdev containing the pixel array,
+ the frame rate cannot be obtained from that information. This is
+ because only on the pixel array it can be assumed that the vertical
+ and horizontal blanking information is exact: no other blanking is
+ allowed in the pixel array. The selection of frame rate is performed
+ by selecting the desired horizontal and vertical blanking. The unit
+ of this control is Hz.
+
+``V4L2_CID_PIXEL_RATE (64-bit integer)``
+ Pixel rate in the source pads of the subdev. This control is
+ read-only and its unit is pixels / second.
+
+``V4L2_CID_TEST_PATTERN (menu)``
+ Some capture/display/sensor devices have the capability to generate
+ test pattern images. These hardware specific test patterns can be
+ used to test if a device is working properly.
+
+``V4L2_CID_DEINTERLACING_MODE (menu)``
+ The video deinterlacing mode (such as Bob, Weave, ...). The menu items are
+ driver specific and are documented in :ref:`v4l-drivers`.
+
+``V4L2_CID_DIGITAL_GAIN (integer)``
+ Digital gain is the value by which all colour components
+ are multiplied by. Typically the digital gain applied is the
+ control value divided by e.g. 0x100, meaning that to get no
+ digital gain the control value needs to be 0x100. The no-gain
+ configuration is also typically the default.

+RF Tuner Control Reference
+**************************
+
+The RF Tuner (RF_TUNER) class includes controls for common features of
+devices having RF tuner.
+
+In this context, RF tuner is radio receiver circuit between antenna and
+demodulator. It receives radio frequency (RF) from the antenna and
+converts that received signal to lower intermediate frequency (IF) or
+baseband frequency (BB). Tuners that could do baseband output are often
+called Zero-IF tuners. Older tuners were typically simple PLL tuners
+inside a metal box, while newer ones are highly integrated chips
+without a metal box "silicon tuners". These controls are mostly
+applicable for new feature rich silicon tuners, just because older
+tuners does not have much adjustable features.
+
+For more information about RF tuners see
+`Tuner (radio) <http://en.wikipedia.org/wiki/Tuner_%28radio%29>`__
+and `RF front end <http://en.wikipedia.org/wiki/RF_front_end>`__

+ Enables/disables tuner radio channel bandwidth configuration. In
+ automatic mode bandwidth configuration is performed by the driver.
+
+``V4L2_CID_RF_TUNER_BANDWIDTH (integer)``
+ Filter(s) on tuner signal path are used to filter signal according
+ to receiving party needs. Driver configures filters to fulfill
+ desired bandwidth requirement. Used when
+ V4L2_CID_RF_TUNER_BANDWIDTH_AUTO is not set. Unit is in Hz. The

+``V4L2_CID_RF_TUNER_IF_GAIN_AUTO (boolean)``
+ Enables/disables IF automatic gain control (AGC)
+
+``V4L2_CID_RF_TUNER_RF_GAIN (integer)``
+ The RF amplifier is the very first amplifier on the receiver signal
+ path, just right after the antenna input. The difference between the
+ LNA gain and the RF gain in this document is that the LNA gain is
+ integrated in the tuner chip while the RF gain is a separate chip.
+ There may be both RF and LNA gain controls in the same device. The
+ range and step are driver-specific.
+
+``V4L2_CID_RF_TUNER_LNA_GAIN (integer)``
+ LNA (low noise amplifier) gain is first gain stage on the RF tuner
+ signal path. It is located very close to tuner antenna input. Used
+ when ``V4L2_CID_RF_TUNER_LNA_GAIN_AUTO`` is not set. See
+ ``V4L2_CID_RF_TUNER_RF_GAIN`` to understand how RF gain and LNA gain
+ differs from the each others. The range and step are
+ driver-specific.
+
+``V4L2_CID_RF_TUNER_MIXER_GAIN (integer)``
+ Mixer gain is second gain stage on the RF tuner signal path. It is
+ located inside mixer block, where RF signal is down-converted by the
+ mixer. Used when ``V4L2_CID_RF_TUNER_MIXER_GAIN_AUTO`` is not set.
+ The range and step are driver-specific.
+
+``V4L2_CID_RF_TUNER_IF_GAIN (integer)``
+ IF gain is last gain stage on the RF tuner signal path. It is
+ located on output of RF tuner. It controls signal level of
+ intermediate frequency output or baseband output. Used when
+ ``V4L2_CID_RF_TUNER_IF_GAIN_AUTO`` is not set. The range and step
+ are driver-specific.
+
+``V4L2_CID_RF_TUNER_PLL_LOCK (boolean)``
+ Is synthesizer PLL locked? RF tuner is receiving given frequency
+ when that control is set. This is a read-only control.

- bitrate target. Otherwise the rate control logic calculates the
- overall average bitrate for the stream and keeps it below or equal
- to the set bitrate. In the first case the average bitrate for the
- whole stream will be smaller then the set bitrate. This is caused
- because the average is calculated for smaller number of frames, on
- the other hand enabling this setting will ensure that the stream
- will meet tight bandwidth constraints. Applicable to encoders.

-
-.. flat-table::
- :header-rows: 0
- :stub-columns: 0
-
- * - ``V4L2_SCENE_MODE_NONE``
- - The scene mode feature is disabled.
- * - ``V4L2_SCENE_MODE_BACKLIGHT``
- - Backlight. Compensates for dark shadows when light is coming from
- behind a subject, also by automatically turning on the flash.
- * - ``V4L2_SCENE_MODE_BEACH_SNOW``
- - Beach and snow. This mode compensates for all-white or bright
- scenes, which tend to look gray and low contrast, when camera's
- automatic exposure is based on an average scene brightness. To
- compensate, this mode automatically slightly overexposes the
- frames. The white balance may also be adjusted to compensate for
- the fact that reflected snow looks bluish rather than white.
- * - ``V4L2_SCENE_MODE_CANDLELIGHT``
- - Candle light. The camera generally raises the ISO sensitivity and
- lowers the shutter speed. This mode compensates for relatively
- close subject in the scene. The flash is disabled in order to
- preserve the ambiance of the light.
- * - ``V4L2_SCENE_MODE_DAWN_DUSK``
- - Dawn and dusk. Preserves the colors seen in low natural light
- before dusk and after down. The camera may turn off the flash, and
- automatically focus at infinity. It will usually boost saturation
- and lower the shutter speed.
- * - ``V4L2_SCENE_MODE_FALL_COLORS``
- - Fall colors. Increases saturation and adjusts white balance for
- color enhancement. Pictures of autumn leaves get saturated reds
- and yellows.

- depth of field and long exposure duration to help capture detail
- in dim light conditions. The focus is fixed at infinity. Suitable
- for distant and wide scenery.
- * - ``V4L2_SCENE_MODE_NIGHT``
- - Night, also known as Night Landscape. Designed for low light
- conditions, it preserves detail in the dark areas without blowing
- out bright objects. The camera generally sets itself to a
- medium-to-high ISO sensitivity, with a relatively long exposure
- time, and turns flash off. As such, there will be increased image
- noise and the possibility of blurred image.
- * - ``V4L2_SCENE_MODE_PARTY_INDOOR``
- - Party and indoor. Designed to capture indoor scenes that are lit
- by indoor background lighting as well as the flash. The camera
- usually increases ISO sensitivity, and adjusts exposure for the
- low light conditions.
- * - ``V4L2_SCENE_MODE_PORTRAIT``
- - Portrait. The camera adjusts the aperture so that the depth of
- field is reduced, which helps to isolate the subject against a
- smooth background. Most cameras recognize the presence of faces in
- the scene and focus on them. The color hue is adjusted to enhance
- skin tones. The intensity of the flash is often reduced.
- * - ``V4L2_SCENE_MODE_SPORTS``
- - Sports. Significantly increases ISO and uses a fast shutter speed
- to freeze motion of rapidly-moving subjects. Increased image noise
- may be seen in this mode.
- * - ``V4L2_SCENE_MODE_SUNSET``
- - Sunset. Preserves deep hues seen in sunsets and sunrises. It bumps
- up the saturation.
- * - ``V4L2_SCENE_MODE_TEXT``

- black-and-white mode optimized for readability. Automatic focus
- may be switched to close-up mode and this setting may also involve
- some lens-distortion correction.
-
-
-
-``V4L2_CID_3A_LOCK (bitmask)``
- This control locks or unlocks the automatic focus, exposure and
- white balance. The automatic adjustments can be paused independently
- by setting the corresponding lock bit to 1. The camera then retains
- the settings until the lock bit is cleared. The following lock bits
- are defined:
-
- When a given algorithm is not enabled, drivers should ignore
- requests to lock it and should return no error. An example might be
- an application setting bit ``V4L2_LOCK_WHITE_BALANCE`` when the
- ``V4L2_CID_AUTO_WHITE_BALANCE`` control is set to ``FALSE``. The
- value of this control may be changed by exposure, white balance or
- focus controls.

- RadioText should be used in addition to ``V4L2_CID_RDS_TX_PS_NAME``.
- The encoding for Radio Text strings is also fully described in Annex
- E of :ref:`iec62106`. The length of Radio Text strings depends on
- which RDS Block is being used to transmit it, either 32 (2A block)
- or 64 (2B block). However, it is also possible to find receivers
- which can scroll strings sized as 32 x N or 64 x N characters. So,

-
-Supported use cases
--------------------
-
-
-Unsynchronised LED flash (software strobe)
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Unsynchronised LED flash is controlled directly by the host as the
-sensor. The flash must be enabled by the host before the exposure of the
-image starts and disabled once it ends. The host is fully responsible
-for the timing of the flash.
-
-Example of such device: Nokia N900.
-
-
-Synchronised LED flash (hardware strobe)
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The synchronised LED flash is pre-programmed by the host (power and
-timeout) but controlled by the sensor through a strobe signal from the
-sensor to the flash.
-
-The sensor controls the flash duration and timing. This information
-typically must be made available to the sensor.
-
-
-LED flash as torch
-^^^^^^^^^^^^^^^^^^
-
-LED flash may be used as torch in conjunction with another use case
-involving camera or individually.

-.. _image-source-controls:
-
-Image Source Control Reference
-==============================
-
-The Image Source control class is intended for low-level control of
-image source devices such as image sensors. The devices feature an
-analogue to digital converter and a bus transmitter to transmit the
-image data out of the device.
-
-
-.. _image-source-control-id:
-
-Image Source Control IDs
-------------------------
-
-``V4L2_CID_IMAGE_SOURCE_CLASS (class)``
- The IMAGE_SOURCE class descriptor.
-
-``V4L2_CID_VBLANK (integer)``
- Vertical blanking. The idle period after every frame during which no
- image data is produced. The unit of vertical blanking is a line.
- Every line has length of the image width plus horizontal blanking at
- the pixel rate defined by ``V4L2_CID_PIXEL_RATE`` control in the
- same sub-device.
-
-``V4L2_CID_HBLANK (integer)``
- Horizontal blanking. The idle period after every line of image data
- during which no image data is produced. The unit of horizontal
- blanking is pixels.
-
-``V4L2_CID_ANALOGUE_GAIN (integer)``
- Analogue gain is gain affecting all colour components in the pixel
- matrix. The gain operation is performed in the analogue domain
- before A/D conversion.
-
-``V4L2_CID_TEST_PATTERN_RED (integer)``
- Test pattern red colour component.
-
-``V4L2_CID_TEST_PATTERN_GREENR (integer)``
- Test pattern green (next to red) colour component.
-
-``V4L2_CID_TEST_PATTERN_BLUE (integer)``
- Test pattern blue colour component.
-
-``V4L2_CID_TEST_PATTERN_GREENB (integer)``
- Test pattern green (next to blue) colour component.
-
-
-.. _image-process-controls:
-
-Image Process Control Reference
-===============================
-
-The Image Process control class is intended for low-level control of
-image processing functions. Unlike ``V4L2_CID_IMAGE_SOURCE_CLASS``, the
-controls in this class affect processing the image, and do not control
-capturing of it.
-
-
-.. _image-process-control-id:
-
-Image Process Control IDs
--------------------------
-
-``V4L2_CID_IMAGE_PROC_CLASS (class)``
- The IMAGE_PROC class descriptor.
-
-``V4L2_CID_LINK_FREQ (integer menu)``
- Data bus frequency. Together with the media bus pixel code, bus type
- (clock cycles per sample), the data bus frequency defines the pixel
- rate (``V4L2_CID_PIXEL_RATE``) in the pixel array (or possibly
- elsewhere, if the device is not an image sensor). The frame rate can
- be calculated from the pixel clock, image width and height and
- horizontal and vertical blanking. While the pixel rate control may
- be defined elsewhere than in the subdev containing the pixel array,
- the frame rate cannot be obtained from that information. This is
- because only on the pixel array it can be assumed that the vertical
- and horizontal blanking information is exact: no other blanking is
- allowed in the pixel array. The selection of frame rate is performed
- by selecting the desired horizontal and vertical blanking. The unit
- of this control is Hz.
-
-``V4L2_CID_PIXEL_RATE (64-bit integer)``
- Pixel rate in the source pads of the subdev. This control is
- read-only and its unit is pixels / second.
-
-``V4L2_CID_TEST_PATTERN (menu)``
- Some capture/display/sensor devices have the capability to generate
- test pattern images. These hardware specific test patterns can be
- used to test if a device is working properly.
-
-``V4L2_CID_DEINTERLACING_MODE (menu)``
- The video deinterlacing mode (such as Bob, Weave, ...). The menu items are
- driver specific and are documented in :ref:`v4l-drivers`.
-
-``V4L2_CID_DIGITAL_GAIN (integer)``
- Digital gain is the value by which all colour components
- are multiplied by. Typically the digital gain applied is the
- control value divided by e.g. 0x100, meaning that to get no
- digital gain the control value needs to be 0x100. The no-gain
- configuration is also typically the default.
-
-
-.. _dv-controls:
-
-Digital Video Control Reference
-===============================
-
-The Digital Video control class is intended to control receivers and
-transmitters for `VGA <http://en.wikipedia.org/wiki/Vga>`__,
-`DVI <http://en.wikipedia.org/wiki/Digital_Visual_Interface>`__
-(Digital Visual Interface), HDMI (:ref:`hdmi`) and DisplayPort
-(:ref:`dp`). These controls are generally expected to be private to
-the receiver or transmitter subdevice that implements them, so they are
-only exposed on the ``/dev/v4l-subdev*`` device node.
-
-.. note::
-
- Note that these devices can have multiple input or output pads which are
- hooked up to e.g. HDMI connectors. Even though the subdevice will
- receive or transmit video from/to only one of those pads, the other pads
- can still be active when it comes to EDID (Extended Display
- Identification Data, :ref:`vesaedid`) and HDCP (High-bandwidth Digital
- Content Protection System, :ref:`hdcp`) processing, allowing the
- device to do the fairly slow EDID/HDCP handling in advance. This allows
- for quick switching between connectors.
-
-These pads appear in several of the controls in this section as
-bitmasks, one bit for each pad. Bit 0 corresponds to pad 0, bit 1 to pad
-1, etc. The maximum value of the control is the set of valid pads.
-
-
-.. _dv-control-id:
-
-Digital Video Control IDs
--------------------------
-
-``V4L2_CID_DV_CLASS (class)``
- The Digital Video class descriptor.
-
-``V4L2_CID_DV_TX_HOTPLUG (bitmask)``
- Many connectors have a hotplug pin which is high if EDID information
- is available from the source. This control shows the state of the
- hotplug pin as seen by the transmitter. Each bit corresponds to an
- output pad on the transmitter. If an output pad does not have an
- associated hotplug pin, then the bit for that pad will be 0. This
- read-only control is applicable to DVI-D, HDMI and DisplayPort
- connectors.
-
-``V4L2_CID_DV_TX_RXSENSE (bitmask)``
- Rx Sense is the detection of pull-ups on the TMDS clock lines. This
- normally means that the sink has left/entered standby (i.e. the
- transmitter can sense that the receiver is ready to receive video).
- Each bit corresponds to an output pad on the transmitter. If an
- output pad does not have an associated Rx Sense, then the bit for
- that pad will be 0. This read-only control is applicable to DVI-D
- and HDMI devices.
-
-``V4L2_CID_DV_TX_EDID_PRESENT (bitmask)``
- When the transmitter sees the hotplug signal from the receiver it
- will attempt to read the EDID. If set, then the transmitter has read
- at least the first block (= 128 bytes). Each bit corresponds to an
- output pad on the transmitter. If an output pad does not support
- EDIDs, then the bit for that pad will be 0. This read-only control
- is applicable to VGA, DVI-A/D, HDMI and DisplayPort connectors.
-
-``V4L2_CID_DV_TX_MODE``
- (enum)
-
-enum v4l2_dv_tx_mode -

- mode to use: V4L2_DV_TX_MODE_DVI_D or V4L2_DV_TX_MODE_HDMI.
- This control is applicable to HDMI connectors.
-
-``V4L2_CID_DV_TX_RGB_RANGE``
- (enum)
-
-enum v4l2_dv_rgb_range -
- Select the quantization range for RGB output. V4L2_DV_RANGE_AUTO

- video interface (ie. :ref:`cea861` for HDMI).
- V4L2_DV_RANGE_LIMITED and V4L2_DV_RANGE_FULL override the
- standard to be compatible with sinks that have not implemented the
- standard correctly (unfortunately quite common for HDMI and DVI-D).
- Full range allows all possible values to be used whereas limited
- range sets the range to (16 << (N-8)) - (235 << (N-8)) where N is
- the number of bits per component. This control is applicable to VGA,
- DVI-A/D, HDMI and DisplayPort connectors.
-
-``V4L2_CID_DV_TX_IT_CONTENT_TYPE``
- (enum)
-
-enum v4l2_dv_it_content_type -
- Configures the IT Content Type of the transmitted video. This
- information is sent over HDMI and DisplayPort connectors as part of
- the AVI InfoFrame. The term 'IT Content' is used for content that
- originates from a computer as opposed to content from a TV broadcast
- or an analog source. The enum v4l2_dv_it_content_type defines
- the possible content types:
-
-.. tabularcolumns:: |p{7.0cm}|p{10.5cm}|

- * - ``V4L2_DV_IT_CONTENT_TYPE_NO_ITC``
- - No IT Content information is available and the ITC bit in the AVI
- InfoFrame is set to 0.
-
-
-
-``V4L2_CID_DV_RX_POWER_PRESENT (bitmask)``
- Detects whether the receiver receives power from the source (e.g.
- HDMI carries 5V on one of the pins). This is often used to power an
- eeprom which contains EDID information, such that the source can
- read the EDID even if the sink is in standby/power off. Each bit
- corresponds to an input pad on the receiver. If an input pad
- cannot detect whether power is present, then the bit for that pad
- will be 0. This read-only control is applicable to DVI-D, HDMI and
- DisplayPort connectors.
-

- Enables/disables RDS reception by the radio tuner
-
-``V4L2_CID_RDS_RX_PTY (integer)``
- Gets RDS Programme Type field. This encodes up to 31 pre-defined
- programme types.
-
-``V4L2_CID_RDS_RX_PS_NAME (string)``
- Gets the Programme Service name (PS_NAME). It is intended for
- static display on a receiver. It is the primary aid to listeners in
- programme service identification and selection. In Annex E of
- :ref:`iec62106`, the RDS specification, there is a full
- description of the correct character encoding for Programme Service
- name strings. Also from RDS specification, PS is usually a single
- eight character text. However, it is also possible to find receivers
- which can scroll strings sized as 8 x N characters. So, this control
- must be configured with steps of 8 characters. The result is it must
- always contain a string with size multiple of 8.
-
-``V4L2_CID_RDS_RX_RADIO_TEXT (string)``
- Gets the Radio Text info. It is a textual description of what is
- being broadcasted. RDS Radio Text can be applied when broadcaster
- wishes to transmit longer PS names, programme-related information or
- any other text. In these cases, RadioText can be used in addition to
- ``V4L2_CID_RDS_RX_PS_NAME``. The encoding for Radio Text strings is
- also fully described in Annex E of :ref:`iec62106`. The length of
- Radio Text strings depends on which RDS Block is being used to
- transmit it, either 32 (2A block) or 64 (2B block). However, it is
- also possible to find receivers which can scroll strings sized as 32
- x N or 64 x N characters. So, this control must be configured with

-``V4L2_CID_TUNE_DEEMPHASIS``
- (enum)
-
-enum v4l2_deemphasis -
- Configures the de-emphasis value for reception. A de-emphasis filter
- is applied to the broadcast to accentuate the high audio
- frequencies. Depending on the region, a time constant of either 50
- or 75 useconds is used. The enum v4l2_deemphasis defines possible
- values for de-emphasis. Here they are:
-
-
-
-.. flat-table::
- :header-rows: 0
- :stub-columns: 0
-

-.. _rf-tuner-controls:
-
-RF Tuner Control Reference
-==========================
-
-The RF Tuner (RF_TUNER) class includes controls for common features of
-devices having RF tuner.
-
-In this context, RF tuner is radio receiver circuit between antenna and
-demodulator. It receives radio frequency (RF) from the antenna and
-converts that received signal to lower intermediate frequency (IF) or
-baseband frequency (BB). Tuners that could do baseband output are often
-called Zero-IF tuners. Older tuners were typically simple PLL tuners
-inside a metal box, whilst newer ones are highly integrated chips
-without a metal box "silicon tuners". These controls are mostly
-applicable for new feature rich silicon tuners, just because older
-tuners does not have much adjustable features.
-
-For more information about RF tuners see
-`Tuner (radio) <http://en.wikipedia.org/wiki/Tuner_%28radio%29>`__
-and `RF front end <http://en.wikipedia.org/wiki/RF_front_end>`__
-from Wikipedia.

- LNA gain and the RF gain in this document is that the LNA gain is
- integrated in the tuner chip while the RF gain is a separate chip.
- There may be both RF and LNA gain controls in the same device. The
- range and step are driver-specific.
-
-``V4L2_CID_RF_TUNER_LNA_GAIN (integer)``

- The range and step are driver-specific.
-
-``V4L2_CID_RF_TUNER_IF_GAIN (integer)``

+Depth sensor confidence information as a 4 bits per pixel packed array
+
+Description
+===========
+
+Proprietary format used by Intel RealSense Depth cameras containing depth
+confidence information in range 0-15 with 0 indicating that the sensor was
+unable to resolve any signal and 15 indicating maximum level of confidence for
+the specific sensor (actual error margins might change from sensor to sensor).
+
+Every two consecutive pixels are packed into a single byte.
+Bits 0-3 of byte n refer to confidence value of depth pixel 2*n,
+bits 4-7 to confidence value of depth pixel 2*n+1.
+
+**Bit-packed representation.**

+3A statistics
+=============
+
+The IPU3 ImgU 3A statistics accelerators collect different statistics over
+an input Bayer frame. Those statistics are obtained from the "ipu3-imgu [01] 3a
+stat" metadata capture video nodes, using the :c:type:`v4l2_meta_format`
+interface. They are formatted as described by the :c:type:`ipu3_uapi_stats_3a`
+structure.
+
+The statistics collected are AWB (Auto-white balance) RGBS (Red, Green, Blue and
+Saturation measure) cells, AWB filter response, AF (Auto-focus) filter response,
+and AE (Auto-exposure) histogram.
+
+The struct :c:type:`ipu3_uapi_4a_config` saves all configurable parameters.

+Pipeline parameters
+===================
+
+The pipeline parameters are passed to the "ipu3-imgu [01] parameters" metadata
+output video nodes, using the :c:type:`v4l2_meta_format` interface. They are
+formatted as described by the :c:type:`ipu3_uapi_params` structure.
+
+Both 3A statistics and pipeline parameters described here are closely tied to
+the underlying camera sub-system (CSS) APIs. They are usually consumed and
+produced by dedicated user space libraries that comprise the important tuning
+tools, thus freeing the developers from being bothered with the low level
+hardware and algorithm details.

+i.MX7 Video Capture Driver
+==========================
+
+Introduction
+------------
+
+The i.MX7 contrary to the i.MX5/6 family does not contain an Image Processing
+Unit (IPU); because of that the capabilities to perform operations or
+manipulation of the capture frames are less feature rich.
+
+For image capture the i.MX7 has three units:
+- CMOS Sensor Interface (CSI)
+- Video Multiplexer
+- MIPI CSI-2 Receiver
+
+.. code-block:: none
+
+ MIPI Camera Input ---> MIPI CSI-2 --- > |\
+ | \
+ | \
+ | M |
+ | U | ------> CSI ---> Capture
+ | X |
+ | /
+ Parallel Camera Input ----------------> | /
+ |/
+
+For additional information, please refer to the latest versions of the i.MX7
+reference manual [#f1]_.
+
+Entities
+--------
+
+imx7-mipi-csi2
+--------------
+
+This is the MIPI CSI-2 receiver entity. It has one sink pad to receive the pixel
+data from MIPI CSI-2 camera sensor. It has one source pad, corresponding to the
+virtual channel 0. This module is compliant to previous version of Samsung
+D-phy, and supports two D-PHY Rx Data lanes.
+
+csi_mux
+-------
+
+This is the video multiplexer. It has two sink pads to select from either camera
+sensor with a parallel interface or from MIPI CSI-2 virtual channel 0. It has
+a single source pad that routes to the CSI.
+
+csi
+---
+
+The CSI enables the chip to connect directly to external CMOS image sensor. CSI
+can interface directly with Parallel and MIPI CSI-2 buses. It has 256 x 64 FIFO
+to store received image pixel data and embedded DMA controllers to transfer data
+from the FIFO through AHB bus.
+
+This entity has one sink pad that receives from the csi_mux entity and a single
+source pad that routes video frames directly to memory buffers. This pad is
+routed to a capture device node.
+
+Usage Notes
+-----------
+
+To aid in configuration and for backward compatibility with V4L2 applications
+that access controls only from video device nodes, the capture device interfaces
+inherit controls from the active entities in the current pipeline, so controls
+can be accessed either directly from the subdev or from the active capture
+device interface. For example, the sensor controls are available either from the
+sensor subdevs or from the active capture device.
+
+Warp7 with OV2680
+-----------------
+
+On this platform an OV2680 MIPI CSI-2 module is connected to the internal MIPI
+CSI-2 receiver. The following example configures a video capture pipeline with
+an output of 800x600, and BGGR 10 bit bayer format:
+
+.. code-block:: none
+
+ # Setup links
+ media-ctl -l "'ov2680 1-0036':0 -> 'imx7-mipi-csis.0':0[1]"

+ media-ctl -l "'csi_mux':2 -> 'csi':0[1]"
+ media-ctl -l "'csi':1 -> 'csi capture':0[1]"

+Intel Image Processing Unit 3 (IPU3) Imaging Unit (ImgU) driver
+===============================================================
+
+Copyright |copy| 2018 Intel Corporation
+
+Introduction
+============
+
+This file documents the Intel IPU3 (3rd generation Image Processing Unit)
+Imaging Unit drivers located under drivers/media/pci/intel/ipu3 (CIO2) as well
+as under drivers/staging/media/ipu3 (ImgU).
+
+The Intel IPU3 found in certain Kaby Lake (as well as certain Sky Lake)
+platforms (U/Y processor lines) is made up of two parts namely the Imaging Unit
+(ImgU) and the CIO2 device (MIPI CSI2 receiver).
+
+The CIO2 device receives the raw Bayer data from the sensors and outputs the
+frames in a format that is specific to the IPU3 (for consumption by the IPU3
+ImgU). The CIO2 driver is available as drivers/media/pci/intel/ipu3/ipu3-cio2*
+and is enabled through the CONFIG_VIDEO_IPU3_CIO2 config option.
+
+The Imaging Unit (ImgU) is responsible for processing images captured
+by the IPU3 CIO2 device. The ImgU driver sources can be found under
+drivers/staging/media/ipu3 directory. The driver is enabled through the
+CONFIG_VIDEO_IPU3_IMGU config option.
+
+The two driver modules are named ipu3_csi2 and ipu3_imgu, respectively.
+
+The drivers has been tested on Kaby Lake platforms (U/Y processor lines).
+
+Both of the drivers implement V4L2, Media Controller and V4L2 sub-device
+interfaces. The IPU3 CIO2 driver supports camera sensors connected to the CIO2
+MIPI CSI-2 interfaces through V4L2 sub-device sensor drivers.
+
+CIO2
+====
+
+The CIO2 is represented as a single V4L2 subdev, which provides a V4L2 subdev
+interface to the user space. There is a video node for each CSI-2 receiver,
+with a single media controller interface for the entire device.
+
+The CIO2 contains four independent capture channel, each with its own MIPI CSI-2
+receiver and DMA engine. Each channel is modelled as a V4L2 sub-device exposed
+to userspace as a V4L2 sub-device node and has two pads:
+
+.. tabularcolumns:: |p{0.8cm}|p{4.0cm}|p{4.0cm}|
+
+.. flat-table::
+
+ * - pad
+ - direction
+ - purpose
+
+ * - 0
+ - sink
+ - MIPI CSI-2 input, connected to the sensor subdev
+
+ * - 1
+ - source
+ - Raw video capture, connected to the V4L2 video interface
+
+The V4L2 video interfaces model the DMA engines. They are exposed to userspace
+as V4L2 video device nodes.
+
+Capturing frames in raw Bayer format
+------------------------------------
+
+CIO2 MIPI CSI2 receiver is used to capture frames (in packed raw Bayer format)
+from the raw sensors connected to the CSI2 ports. The captured frames are used
+as input to the ImgU driver.
+
+Image processing using IPU3 ImgU requires tools such as raw2pnm [#f1]_, and
+yavta [#f2]_ due to the following unique requirements and / or features specific
+to IPU3.
+
+-- The IPU3 CSI2 receiver outputs the captured frames from the sensor in packed
+raw Bayer format that is specific to IPU3.
+
+-- Multiple video nodes have to be operated simultaneously.
+
+Let us take the example of ov5670 sensor connected to CSI2 port 0, for a
+2592x1944 image capture.
+
+Using the media contorller APIs, the ov5670 sensor is configured to send
+frames in packed raw Bayer format to IPU3 CSI2 receiver.
+
+# This example assumes /dev/media0 as the CIO2 media device
+
+export MDEV=/dev/media0
+
+# and that ov5670 sensor is connected to i2c bus 10 with address 0x36
+
+export SDEV=$(media-ctl -d $MDEV -e "ov5670 10-0036")
+
+# Establish the link for the media devices using media-ctl [#f3]_
+media-ctl -d $MDEV -l "ov5670:0 -> ipu3-csi2 0:0[1]"
+
+# Set the format for the media devices
+media-ctl -d $MDEV -V "ov5670:0 [fmt:SGRBG10/2592x1944]"
+
+media-ctl -d $MDEV -V "ipu3-csi2 0:0 [fmt:SGRBG10/2592x1944]"
+
+media-ctl -d $MDEV -V "ipu3-csi2 0:1 [fmt:SGRBG10/2592x1944]"
+
+Once the media pipeline is configured, desired sensor specific settings
+(such as exposure and gain settings) can be set, using the yavta tool.
+
+e.g
+
+yavta -w 0x009e0903 444 $SDEV
+
+yavta -w 0x009e0913 1024 $SDEV
+
+yavta -w 0x009e0911 2046 $SDEV
+
+Once the desired sensor settings are set, frame captures can be done as below.
+
+e.g
+
+yavta --data-prefix -u -c10 -n5 -I -s2592x1944 --file=/tmp/frame-#.bin \
+ -f IPU3_SGRBG10 $(media-ctl -d $MDEV -e "ipu3-cio2 0")
+
+With the above command, 10 frames are captured at 2592x1944 resolution, with
+sGRBG10 format and output as IPU3_SGRBG10 format.
+
+The captured frames are available as /tmp/frame-#.bin files.
+
+ImgU
+====
+
+The ImgU is represented as two V4L2 subdevs, each of which provides a V4L2
+subdev interface to the user space.
+
+Each V4L2 subdev represents a pipe, which can support a maximum of 2 streams.
+This helps to support advanced camera features like Continuous View Finder (CVF)
+and Snapshot During Video(SDV).
+
+The ImgU contains two independent pipes, each modelled as a V4L2 sub-device
+exposed to userspace as a V4L2 sub-device node.
+
+Each pipe has two sink pads and three source pads for the following purpose:
+
+.. tabularcolumns:: |p{0.8cm}|p{4.0cm}|p{4.0cm}|
+
+.. flat-table::
+
+ * - pad
+ - direction
+ - purpose
+
+ * - 0
+ - sink
+ - Input raw video stream
+
+ * - 1
+ - sink
+ - Processing parameters
+
+ * - 2
+ - source
+ - Output processed video stream
+
+ * - 3
+ - source
+ - Output viewfinder video stream
+
+ * - 4
+ - source
+ - 3A statistics
+
+Each pad is connected to a corresponding V4L2 video interface, exposed to
+userspace as a V4L2 video device node.
+
+Device operation
+----------------
+
+With ImgU, once the input video node ("ipu3-imgu 0/1":0, in
+<entity>:<pad-number> format) is queued with buffer (in packed raw Bayer
+format), ImgU starts processing the buffer and produces the video output in YUV
+format and statistics output on respective output nodes. The driver is expected
+to have buffers ready for all of parameter, output and statistics nodes, when
+input video node is queued with buffer.
+
+At a minimum, all of input, main output, 3A statistics and viewfinder
+video nodes should be enabled for IPU3 to start image processing.
+
+Each ImgU V4L2 subdev has the following set of video nodes.
+
+input, output and viewfinder video nodes
+----------------------------------------
+
+The frames (in packed raw Bayer format specific to the IPU3) received by the
+input video node is processed by the IPU3 Imaging Unit and are output to 2 video
+nodes, with each targeting a different purpose (main output and viewfinder
+output).
+
+Details onand the Bayer format specific to the IPU3 can be found in
+:ref:`v4l2-pix-fmt-ipu3-sbggr10`.
+
+The driver supports V4L2 Video Capture Interface as defined at :ref:`devices`.
+
+Only the multi-planar API is supported. More details can be found at
+:ref:`planar-apis`.
+
+Parameters video node
+---------------------
+
+The parameters video node receives the ImgU algorithm parameters that are used
+to configure how the ImgU algorithms process the image.
+
+Details on processing parameters specific to the IPU3 can be found in
+:ref:`v4l2-meta-fmt-params`.
+
+3A statistics video node
+------------------------
+
+3A statistics video node is used by the ImgU driver to output the 3A (auto
+focus, auto exposure and auto white balance) statistics for the frames that are
+being processed by the ImgU to user space applications. User space applications
+can use this statistics data to compute the desired algorithm parameters for
+the ImgU.
+
+Configuring the Intel IPU3
+==========================
+
+The IPU3 ImgU pipelines can be configured using the Media Controller, defined at
+:ref:`media_controller`.
+
+Firmware binary selection
+-------------------------
+
+The firmware binary is selected using the V4L2_CID_INTEL_IPU3_MODE, currently
+defined in drivers/staging/media/ipu3/include/intel-ipu3.h . "VIDEO" and "STILL"
+modes are available.
+
+Processing the image in raw Bayer format
+----------------------------------------
+
+Configuring ImgU V4L2 subdev for image processing
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ImgU V4L2 subdevs have to be configured with media controller APIs to have
+all the video nodes setup correctly.
+
+Let us take "ipu3-imgu 0" subdev as an example.
+
+media-ctl -d $MDEV -r
+
+media-ctl -d $MDEV -l "ipu3-imgu 0 input":0 -> "ipu3-imgu 0":0[1]
+
+media-ctl -d $MDEV -l "ipu3-imgu 0":2 -> "ipu3-imgu 0 output":0[1]
+
+media-ctl -d $MDEV -l "ipu3-imgu 0":3 -> "ipu3-imgu 0 viewfinder":0[1]
+
+media-ctl -d $MDEV -l "ipu3-imgu 0":4 -> "ipu3-imgu 0 3a stat":0[1]
+
+Also the pipe mode of the corresponding V4L2 subdev should be set as desired
+(e.g 0 for video mode or 1 for still mode) through the control id 0x009819a1 as
+below.
+
+yavta -w "0x009819A1 1" /dev/v4l-subdev7
+
+RAW Bayer frames go through the following ImgU pipeline HW blocks to have the
+processed image output to the DDR memory.
+
+RAW Bayer frame -> Input Feeder -> Bayer Down Scaling (BDS) -> Geometric
+Distortion Correction (GDC) -> DDR
+
+The ImgU V4L2 subdev has to be configured with the supported resolutions in all
+the above HW blocks, for a given input resolution.
+
+For a given supported resolution for an input frame, the Input Feeder, Bayer
+Down Scaling and GDC blocks should be configured with the supported resolutions.
+This information can be obtained by looking at the following IPU3 ImgU
+configuration table.
+
+https://chromium.googlesource.com/chromiumos/overlays/board-overlays/+/master
+
+Under baseboard-poppy/media-libs/cros-camera-hal-configs-poppy/files/gcss
+directory, graph_settings_ov5670.xml can be used as an example.
+
+The following steps prepare the ImgU pipeline for the image processing.
+
+1. The ImgU V4L2 subdev data format should be set by using the
+VIDIOC_SUBDEV_S_FMT on pad 0, using the GDC width and height obtained above.
+
+2. The ImgU V4L2 subdev cropping should be set by using the
+VIDIOC_SUBDEV_S_SELECTION on pad 0, with V4L2_SEL_TGT_CROP as the target,
+using the input feeder height and width.
+
+3. The ImgU V4L2 subdev composing should be set by using the
+VIDIOC_SUBDEV_S_SELECTION on pad 0, with V4L2_SEL_TGT_COMPOSE as the target,
+using the BDS height and width.
+
+For the ov5670 example, for an input frame with a resolution of 2592x1944
+(which is input to the ImgU subdev pad 0), the corresponding resolutions
+for input feeder, BDS and GDC are 2592x1944, 2592x1944 and 2560x1920
+respectively.
+
+Once this is done, the received raw Bayer frames can be input to the ImgU
+V4L2 subdev as below, using the open source application v4l2n [#f1]_.
+
+For an image captured with 2592x1944 [#f4]_ resolution, with desired output
+resolution as 2560x1920 and viewfinder resolution as 2560x1920, the following
+v4l2n command can be used. This helps process the raw Bayer frames and produces
+the desired results for the main output image and the viewfinder output, in NV12
+format.
+
+v4l2n --pipe=4 --load=/tmp/frame-#.bin --open=/dev/video4
+--fmt=type:VIDEO_OUTPUT_MPLANE,width=2592,height=1944,pixelformat=0X47337069
+--reqbufs=type:VIDEO_OUTPUT_MPLANE,count:1 --pipe=1 --output=/tmp/frames.out
+--open=/dev/video5
+--fmt=type:VIDEO_CAPTURE_MPLANE,width=2560,height=1920,pixelformat=NV12
+--reqbufs=type:VIDEO_CAPTURE_MPLANE,count:1 --pipe=2 --output=/tmp/frames.vf
+--open=/dev/video6
+--fmt=type:VIDEO_CAPTURE_MPLANE,width=2560,height=1920,pixelformat=NV12
+--reqbufs=type:VIDEO_CAPTURE_MPLANE,count:1 --pipe=3 --open=/dev/video7
+--output=/tmp/frames.3A --fmt=type:META_CAPTURE,?
+--reqbufs=count:1,type:META_CAPTURE --pipe=1,2,3,4 --stream=5
+
+where /dev/video4, /dev/video5, /dev/video6 and /dev/video7 devices point to
+input, output, viewfinder and 3A statistics video nodes respectively.
+
+Converting the raw Bayer image into YUV domain
+----------------------------------------------
+
+The processed images after the above step, can be converted to YUV domain
+as below.
+
+Main output frames
+~~~~~~~~~~~~~~~~~~
+
+raw2pnm -x2560 -y1920 -fNV12 /tmp/frames.out /tmp/frames.out.ppm
+
+where 2560x1920 is output resolution, NV12 is the video format, followed
+by input frame and output PNM file.
+
+Viewfinder output frames
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+raw2pnm -x2560 -y1920 -fNV12 /tmp/frames.vf /tmp/frames.vf.ppm
+
+where 2560x1920 is output resolution, NV12 is the video format, followed
+by input frame and output PNM file.
+
+Example user space code for IPU3
+================================
+
+User space code that configures and uses IPU3 is available here.
+
+https://chromium.googlesource.com/chromiumos/platform/arc-camera/+/master/
+
+The source can be located under hal/intel directory.
+
+Overview of IPU3 pipeline
+=========================
+
+IPU3 pipeline has a number of image processing stages, each of which takes a
+set of parameters as input. The major stages of pipelines are shown here:

+
+The table below presents a description of the above algorithms.
+
+======================== =======================================================
+Name Description
+======================== =======================================================
+Optical Black Correction Optical Black Correction block subtracts a pre-defined
+ value from the respective pixel values to obtain better
+ image quality.
+ Defined in :c:type:`ipu3_uapi_obgrid_param`.
+Linearization This algo block uses linearization parameters to
+ address non-linearity sensor effects. The Lookup table
+ table is defined in
+ :c:type:`ipu3_uapi_isp_lin_vmem_params`.
+SHD Lens shading correction is used to correct spatial
+ non-uniformity of the pixel response due to optical
+ lens shading. This is done by applying a different gain
+ for each pixel. The gain, black level etc are
+ configured in :c:type:`ipu3_uapi_shd_config_static`.
+BNR Bayer noise reduction block removes image noise by
+ applying a bilateral filter.
+ See :c:type:`ipu3_uapi_bnr_static_config` for details.
+ANR Advanced Noise Reduction is a block based algorithm
+ that performs noise reduction in the Bayer domain. The
+ convolution matrix etc can be found in
+ :c:type:`ipu3_uapi_anr_config`.
+DM Demosaicing converts raw sensor data in Bayer format
+ into RGB (Red, Green, Blue) presentation. Then add
+ outputs of estimation of Y channel for following stream
+ processing by Firmware. The struct is defined as
+ :c:type:`ipu3_uapi_dm_config`.
+Color Correction Color Correction algo transforms sensor specific color
+ space to the standard "sRGB" color space. This is done
+ by applying 3x3 matrix defined in
+ :c:type:`ipu3_uapi_ccm_mat_config`.
+Gamma correction Gamma correction :c:type:`ipu3_uapi_gamma_config` is a
+ basic non-linear tone mapping correction that is
+ applied per pixel for each pixel component.
+CSC Color space conversion transforms each pixel from the
+ RGB primary presentation to YUV (Y: brightness,
+ UV: Luminance) presentation. This is done by applying
+ a 3x3 matrix defined in
+ :c:type:`ipu3_uapi_csc_mat_config`
+CDS Chroma down sampling
+ After the CSC is performed, the Chroma Down Sampling
+ is applied for a UV plane down sampling by a factor
+ of 2 in each direction for YUV 4:2:0 using a 4x2
+ configurable filter :c:type:`ipu3_uapi_cds_params`.
+CHNR Chroma noise reduction
+ This block processes only the chrominance pixels and
+ performs noise reduction by cleaning the high
+ frequency noise.
+ See struct :c:type:`ipu3_uapi_yuvp1_chnr_config`.
+TCC Total color correction as defined in struct
+ :c:type:`ipu3_uapi_yuvp2_tcc_static_config`.
+XNR3 eXtreme Noise Reduction V3 is the third revision of
+ noise reduction algorithm used to improve image
+ quality. This removes the low frequency noise in the
+ captured image. Two related structs are being defined,
+ :c:type:`ipu3_uapi_isp_xnr3_params` for ISP data memory
+ and :c:type:`ipu3_uapi_isp_xnr3_vmem_params` for vector
+ memory.
+TNR Temporal Noise Reduction block compares successive
+ frames in time to remove anomalies / noise in pixel
+ values. :c:type:`ipu3_uapi_isp_tnr3_vmem_params` and
+ :c:type:`ipu3_uapi_isp_tnr3_params` are defined for ISP
+ vector and data memory respectively.

+ Obgrid
+ Optical black level compensation
+ OSYS
+ Output system configuration
+ ROI
+ Region of interest
+ YDS
+ Y down sampling
+ YTM
+ Y-tone mapping
+
+A few stages of the pipeline will be executed by firmware running on the ISP
+processor, while many others will use a set of fixed hardware blocks also
+called accelerator cluster (ACC) to crunch pixel data and produce statistics.
+
+ACC parameters of individual algorithms, as defined by
+:c:type:`ipu3_uapi_acc_param`, can be chosen to be applied by the user
+space through struct :c:type:`ipu3_uapi_flags` embedded in
+:c:type:`ipu3_uapi_params` structure. For parameters that are configured as
+not enabled by the user space, the corresponding structs are ignored by the
+driver, in which case the existing configuration of the algorithm will be
+preserved.

+FAQ
+=======
+
+Q: I am not seeing any traffic on the socket. What am I doing wrong?
+
+A: When a netdev of a physical NIC is initialized, Linux usually
+ allocates one Rx and Tx queue pair per core. So on a 8 core system,
+ queue ids 0 to 7 will be allocated, one per core. In the AF_XDP
+ bind call or the xsk_socket__create libbpf function call, you
+ specify a specific queue id to bind to and it is only the traffic
+ towards that queue you are going to get on you socket. So in the
+ example above, if you bind to queue 0, you are NOT going to get any
+ traffic that is distributed to queues 1 through 7. If you are
+ lucky, you will see the traffic, but usually it will end up on one
+ of the queues you have not bound to.
+
+ There are a number of ways to solve the problem of getting the
+ traffic you want to the queue id you bound to. If you want to see
+ all the traffic, you can force the netdev to only have 1 queue, queue
+ id 0, and then bind to queue 0. You can use ethtool to do this::
+
+ sudo ethtool -L <interface> combined 1

+==================
+BPF Flow Dissector
+==================
+
+Overview
+========
+
+Flow dissector is a routine that parses metadata out of the packets. It's
+used in the various places in the networking subsystem (RFS, flow hash, etc).
+
+BPF flow dissector is an attempt to reimplement C-based flow dissector logic
+in BPF to gain all the benefits of BPF verifier (namely, limits on the
+number of instructions and tail calls).
+
+API
+===
+
+BPF flow dissector programs operate on an ``__sk_buff``. However, only the
+limited set of fields is allowed: ``data``, ``data_end`` and ``flow_keys``.
+``flow_keys`` is ``struct bpf_flow_keys`` and contains flow dissector input
+and output arguments.
+
+The inputs are:
+ * ``nhoff`` - initial offset of the networking header
+ * ``thoff`` - initial offset of the transport header, initialized to nhoff
+ * ``n_proto`` - L3 protocol type, parsed out of L2 header
+
+Flow dissector BPF program should fill out the rest of the ``struct
+bpf_flow_keys`` fields. Input arguments ``nhoff/thoff/n_proto`` should be
+also adjusted accordingly.
+
+The return code of the BPF program is either BPF_OK to indicate successful
+dissection, or BPF_DROP to indicate parsing error.
+
+__sk_buff->data
+===============
+
+In the VLAN-less case, this is what the initial state of the BPF flow
+dissector looks like::
+
+ +------+------+------------+-----------+
+ | DMAC | SMAC | ETHER_TYPE | L3_HEADER |
+ +------+------+------------+-----------+
+ ^
+ |
+ +-- flow dissector starts here
+
+
+.. code:: c
+
+ skb->data + flow_keys->nhoff point to the first byte of L3_HEADER
+ flow_keys->thoff = nhoff
+ flow_keys->n_proto = ETHER_TYPE
+
+In case of VLAN, flow dissector can be called with the two different states.
+
+Pre-VLAN parsing::
+
+ +------+------+------+-----+-----------+-----------+
+ | DMAC | SMAC | TPID | TCI |ETHER_TYPE | L3_HEADER |
+ +------+------+------+-----+-----------+-----------+
+ ^
+ |
+ +-- flow dissector starts here
+
+.. code:: c
+
+ skb->data + flow_keys->nhoff point the to first byte of TCI
+ flow_keys->thoff = nhoff
+ flow_keys->n_proto = TPID
+
+Please note that TPID can be 802.1AD and, hence, BPF program would
+have to parse VLAN information twice for double tagged packets.
+
+
+Post-VLAN parsing::
+
+ +------+------+------+-----+-----------+-----------+
+ | DMAC | SMAC | TPID | TCI |ETHER_TYPE | L3_HEADER |
+ +------+------+------+-----+-----------+-----------+
+ ^
+ |
+ +-- flow dissector starts here
+
+.. code:: c
+
+ skb->data + flow_keys->nhoff point the to first byte of L3_HEADER
+ flow_keys->thoff = nhoff
+ flow_keys->n_proto = ETHER_TYPE
+
+In this case VLAN information has been processed before the flow dissector
+and BPF flow dissector is not required to handle it.
+
+
+The takeaway here is as follows: BPF flow dissector program can be called with
+the optional VLAN header and should gracefully handle both cases: when single
+or double VLAN is present and when it is not present. The same program
+can be called for both cases and would have to be written carefully to
+handle both cases.
+
+
+Reference Implementation
+========================
+
+See ``tools/testing/selftests/bpf/progs/bpf_flow.c`` for the reference
+implementation and ``tools/testing/selftests/bpf/flow_dissector_load.[hc]``
+for the loader. bpftool can be used to load BPF flow dissector program as well.
+
+The reference implementation is organized as follows:
+ * ``jmp_table`` map that contains sub-programs for each supported L3 protocol
+ * ``_dissect`` routine - entry point; it does input ``n_proto`` parsing and
+ does ``bpf_tail_call`` to the appropriate L3 handler
+
+Since BPF at this point doesn't support looping (or any jumping back),
+jmp_table is used instead to handle multiple levels of encapsulation (and
+IPv6 options).
+
+
+Current Limitations
+===================
+BPF flow dissector doesn't support exporting all the metadata that in-kernel
+C-based implementation can export. Notable example is single VLAN (802.1Q)
+and double VLAN (802.1AD) tags. Please refer to the ``struct bpf_flow_keys``
+for a set of information that's currently can be exported from the BPF context.

+Checksum Offloads
+=================
+
+
+Introduction
+============
+
+This document describes a set of techniques in the Linux networking stack to
+take advantage of checksum offload capabilities of various NICs.
+
+The following technologies are described:
+
+* TX Checksum Offload
+* LCO: Local Checksum Offload
+* RCO: Remote Checksum Offload
+
+Things that should be documented here but aren't yet:
+
+* RX Checksum Offload
+* CHECKSUM_UNNECESSARY conversion
+
+
+TX Checksum Offload
+===================
+
+The interface for offloading a transmit checksum to a device is explained in
+detail in comments near the top of include/linux/skbuff.h.
+
+In brief, it allows to request the device fill in a single ones-complement
+checksum defined by the sk_buff fields skb->csum_start and skb->csum_offset.
+The device should compute the 16-bit ones-complement checksum (i.e. the
+'IP-style' checksum) from csum_start to the end of the packet, and fill in the
+result at (csum_start + csum_offset).
+
+Because csum_offset cannot be negative, this ensures that the previous value of
+the checksum field is included in the checksum computation, thus it can be used
+to supply any needed corrections to the checksum (such as the sum of the
+pseudo-header for UDP or TCP).
+
+This interface only allows a single checksum to be offloaded. Where
+encapsulation is used, the packet may have multiple checksum fields in
+different header layers, and the rest will have to be handled by another
+mechanism such as LCO or RCO.
+
+CRC32c can also be offloaded using this interface, by means of filling
+skb->csum_start and skb->csum_offset as described above, and setting
+skb->csum_not_inet: see skbuff.h comment (section 'D') for more details.
+
+No offloading of the IP header checksum is performed; it is always done in
+software. This is OK because when we build the IP header, we obviously have it
+in cache, so summing it isn't expensive. It's also rather short.
+
+The requirements for GSO are more complicated, because when segmenting an
+encapsulated packet both the inner and outer checksums may need to be edited or
+recomputed for each resulting segment. See the skbuff.h comment (section 'E')
+for more details.
+
+A driver declares its offload capabilities in netdev->hw_features; see
+Documentation/networking/netdev-features.txt for more. Note that a device
+which only advertises NETIF_F_IP[V6]_CSUM must still obey the csum_start and
+csum_offset given in the SKB; if it tries to deduce these itself in hardware
+(as some NICs do) the driver should check that the values in the SKB match
+those which the hardware will deduce, and if not, fall back to checksumming in
+software instead (with skb_csum_hwoffload_help() or one of the
+skb_checksum_help() / skb_crc32c_csum_help functions, as mentioned in
+include/linux/skbuff.h).
+
+The stack should, for the most part, assume that checksum offload is supported
+by the underlying device. The only place that should check is
+validate_xmit_skb(), and the functions it calls directly or indirectly. That
+function compares the offload features requested by the SKB (which may include
+other offloads besides TX Checksum Offload) and, if they are not supported or
+enabled on the device (determined by netdev->features), performs the
+corresponding offload in software. In the case of TX Checksum Offload, that
+means calling skb_csum_hwoffload_help(skb, features).
+
+
+LCO: Local Checksum Offload
+===========================
+
+LCO is a technique for efficiently computing the outer checksum of an
+encapsulated datagram when the inner checksum is due to be offloaded.
+
+The ones-complement sum of a correctly checksummed TCP or UDP packet is equal
+to the complement of the sum of the pseudo header, because everything else gets
+'cancelled out' by the checksum field. This is because the sum was
+complemented before being written to the checksum field.
+
+More generally, this holds in any case where the 'IP-style' ones complement
+checksum is used, and thus any checksum that TX Checksum Offload supports.
+
+That is, if we have set up TX Checksum Offload with a start/offset pair, we
+know that after the device has filled in that checksum, the ones complement sum
+from csum_start to the end of the packet will be equal to the complement of
+whatever value we put in the checksum field beforehand. This allows us to
+compute the outer checksum without looking at the payload: we simply stop
+summing when we get to csum_start, then add the complement of the 16-bit word
+at (csum_start + csum_offset).
+
+Then, when the true inner checksum is filled in (either by hardware or by
+skb_checksum_help()), the outer checksum will become correct by virtue of the
+arithmetic.
+
+LCO is performed by the stack when constructing an outer UDP header for an
+encapsulation such as VXLAN or GENEVE, in udp_set_csum(). Similarly for the
+IPv6 equivalents, in udp6_set_csum().
+
+It is also performed when constructing an IPv4 GRE header, in
+net/ipv4/ip_gre.c:build_header(). It is *not* currently performed when
+constructing an IPv6 GRE header; the GRE checksum is computed over the whole
+packet in net/ipv6/ip6_gre.c:ip6gre_xmit2(), but it should be possible to use
+LCO here as IPv6 GRE still uses an IP-style checksum.
+
+All of the LCO implementations use a helper function lco_csum(), in
+include/linux/skbuff.h.
+
+LCO can safely be used for nested encapsulations; in this case, the outer
+encapsulation layer will sum over both its own header and the 'middle' header.
+This does mean that the 'middle' header will get summed multiple times, but
+there doesn't seem to be a way to avoid that without incurring bigger costs
+(e.g. in SKB bloat).
+
+
+RCO: Remote Checksum Offload
+============================
+
+RCO is a technique for eliding the inner checksum of an encapsulated datagram,
+allowing the outer checksum to be offloaded. It does, however, involve a
+change to the encapsulation protocols, which the receiver must also support.
+For this reason, it is disabled by default.
+
+RCO is detailed in the following Internet-Drafts:
+
+* https://tools.ietf.org/html/draft-herbert-remotecsumoffload-00
+* https://tools.ietf.org/html/draft-herbert-vxlan-rco-00
+
+In Linux, RCO is implemented individually in each encapsulation protocol, and
+most tunnel types have flags controlling its use. For instance, VXLAN has the
+flag VXLAN_F_REMCSUM_TX (per struct vxlan_rdst) to indicate that RCO should be
+used when transmitting to a given remote destination.

+When enabling the CBS qdisc in the hardware offload mode, traffic shaping using
+the CBS (described in the IEEE 802.1Q-2018 Section 8.6.8.2 and discussed in the
+Annex L) algorithm will run in the i210 controller, so it's more accurate and

+
+When using offloaded CBS, and the traffic rate obeys the configured rate
+(doesn't go above it), CBS should have little to no effect in the latency.
+
+The offloaded version of the algorithm has some limits, caused by how the idle
+slope is expressed in the adapter's registers. It can only represent idle slopes
+in 16.38431 kbps units, which means that if a idle slope of 2576kbps is
+requested, the controller will be configured to use a idle slope of ~2589 kbps,
+because the driver rounds the value up. For more details, see the comments on

+The health mechanism is targeted for Real Time Alerting, in order to know when
+something bad had happened to a PCI device
+- Provide alert debug information
+- Self healing
+- If problem needs vendor support, provide a way to gather all needed debugging
+ information.
+
+The main idea is to unify and centralize driver health reports in the
+generic devlink instance and allow the user to set different
+attributes of the health reporting and recovery procedures.
+
+The devlink health reporter:
+Device driver creates a "health reporter" per each error/health type.
+Error/Health type can be a known/generic (eg pci error, fw error, rx/tx error)
+or unknown (driver specific).
+For each registered health reporter a driver can issue error/health reports
+asynchronously. All health reports handling is done by devlink.
+Device driver can provide specific callbacks for each "health reporter", e.g.
+ - Recovery procedures
+ - Diagnostics and object dump procedures
+ - OOB initial parameters
+Different parts of the driver can register different types of health reporters
+with different handlers.
+
+Once an error is reported, devlink health will do the following actions:
+ * A log is being send to the kernel trace events buffer
+ * Health status and statistics are being updated for the reporter instance
+ * Object dump is being taken and saved at the reporter instance (as long as
+ there is no other dump which is already stored)
+ * Auto recovery attempt is being done. Depends on:
+ - Auto-recovery configuration
+ - Grace period vs. time passed since last recover
+
+The user interface:
+User can access/change each reporter's parameters and driver specific callbacks
+via devlink, e.g per error type (per health reporter)
+ - Configure reporter's generic parameters (like: disable/enable auto recovery)
+ - Invoke recovery procedure
+ - Run diagnostics
+ - Object dump
+
+The devlink health interface (via netlink):
+DEVLINK_CMD_HEALTH_REPORTER_GET
+ Retrieves status and configuration info per DEV and reporter.
+DEVLINK_CMD_HEALTH_REPORTER_SET
+ Allows reporter-related configuration setting.
+DEVLINK_CMD_HEALTH_REPORTER_RECOVER
+ Triggers a reporter's recovery procedure.
+DEVLINK_CMD_HEALTH_REPORTER_DIAGNOSE
+ Retrieves diagnostics data from a reporter on a device.
+DEVLINK_CMD_HEALTH_REPORTER_DUMP_GET
+ Retrieves the last stored dump. Devlink health
+ saves a single dump. If an dump is not already stored by the devlink
+ for this reporter, devlink generates a new dump.
+ dump output is defined by the reporter.
+DEVLINK_CMD_HEALTH_REPORTER_DUMP_CLEAR
+ Clears the last saved dump file for the specified reporter.

+IEEE 802.15.4 Developer's Guide
+===============================
+
+Introduction
+============
+The IEEE 802.15.4 working group focuses on standardization of the bottom
+two layers: Medium Access Control (MAC) and Physical access (PHY). And there
+are mainly two options available for upper layers:
+
+- ZigBee - proprietary protocol from the ZigBee Alliance
+- 6LoWPAN - IPv6 networking over low rate personal area networks
+
+The goal of the Linux-wpan is to provide a complete implementation
+of the IEEE 802.15.4 and 6LoWPAN protocols. IEEE 802.15.4 is a stack
+of protocols for organizing Low-Rate Wireless Personal Area Networks.
+
+The stack is composed of three main parts:
+
+- IEEE 802.15.4 layer; We have chosen to use plain Berkeley socket API,
+ the generic Linux networking stack to transfer IEEE 802.15.4 data
+ messages and a special protocol over netlink for configuration/management
+- MAC - provides access to shared channel and reliable data delivery
+- PHY - represents device drivers
+
+Socket API
+==========
+
+.. c:function:: int sd = socket(PF_IEEE802154, SOCK_DGRAM, 0);
+
+The address family, socket addresses etc. are defined in the
+include/net/af_ieee802154.h header or in the special header
+in the userspace package (see either http://wpan.cakelab.org/ or the
+git tree at https://github.com/linux-wpan/wpan-tools).
+
+6LoWPAN Linux implementation
+============================
+
+The IEEE 802.15.4 standard specifies an MTU of 127 bytes, yielding about 80
+octets of actual MAC payload once security is turned on, on a wireless link
+with a link throughput of 250 kbps or less. The 6LoWPAN adaptation format
+[RFC4944] was specified to carry IPv6 datagrams over such constrained links,
+taking into account limited bandwidth, memory, or energy resources that are
+expected in applications such as wireless Sensor Networks. [RFC4944] defines
+a Mesh Addressing header to support sub-IP forwarding, a Fragmentation header
+to support the IPv6 minimum MTU requirement [RFC2460], and stateless header
+compression for IPv6 datagrams (LOWPAN_HC1 and LOWPAN_HC2) to reduce the
+relatively large IPv6 and UDP headers down to (in the best case) several bytes.
+
+In September 2011 the standard update was published - [RFC6282].
+It deprecates HC1 and HC2 compression and defines IPHC encoding format which is
+used in this Linux implementation.
+
+All the code related to 6lowpan you may find in files: net/6lowpan/*
+and net/ieee802154/6lowpan/*
+
+To setup a 6LoWPAN interface you need:
+1. Add IEEE802.15.4 interface and set channel and PAN ID;
+2. Add 6lowpan interface by command like:
+# ip link add link wpan0 name lowpan0 type lowpan
+3. Bring up 'lowpan0' interface
+
+Drivers
+=======
+
+Like with WiFi, there are several types of devices implementing IEEE 802.15.4.
+1) 'HardMAC'. The MAC layer is implemented in the device itself, the device
+exports a management (e.g. MLME) and data API.
+2) 'SoftMAC' or just radio. These types of devices are just radio transceivers
+possibly with some kinds of acceleration like automatic CRC computation and
+comparation, automagic ACK handling, address matching, etc.
+
+Those types of devices require different approach to be hooked into Linux kernel.
+
+HardMAC
+-------
+
+See the header include/net/ieee802154_netdev.h. You have to implement Linux
+net_device, with .type = ARPHRD_IEEE802154. Data is exchanged with socket family
+code via plain sk_buffs. On skb reception skb->cb must contain additional
+info as described in the struct ieee802154_mac_cb. During packet transmission
+the skb->cb is used to provide additional data to device's header_ops->create
+function. Be aware that this data can be overridden later (when socket code
+submits skb to qdisc), so if you need something from that cb later, you should
+store info in the skb->data on your own.
+
+To hook the MLME interface you have to populate the ml_priv field of your
+net_device with a pointer to struct ieee802154_mlme_ops instance. The fields
+assoc_req, assoc_resp, disassoc_req, start_req, and scan_req are optional.
+All other fields are required.
+
+SoftMAC
+-------
+
+The MAC is the middle layer in the IEEE 802.15.4 Linux stack. This moment it
+provides interface for drivers registration and management of slave interfaces.
+
+NOTE: Currently the only monitor device type is supported - it's IEEE 802.15.4
+stack interface for network sniffers (e.g. WireShark).
+
+This layer is going to be extended soon.
+
+See header include/net/mac802154.h and several drivers in
+drivers/net/ieee802154/.
+
+Fake drivers
+------------
+
+In addition there is a driver available which simulates a real device with
+SoftMAC (fakelb - IEEE 802.15.4 loopback driver) interface. This option
+provides a possibility to test and debug the stack without usage of real hardware.
+
+Device drivers API
+==================
+
+The include/net/mac802154.h defines following functions:
+
+.. c:function:: struct ieee802154_dev *ieee802154_alloc_device (size_t priv_size, struct ieee802154_ops *ops)
+

+
+Telling 802.15.4 module the frame in the skb is or going to be
+transmitted through the hardware device
+
+The device driver must implement the following callbacks in the IEEE 802.15.4

+
+ struct ieee802154_ops {
+ ...
+ int (*start)(struct ieee802154_hw *hw);

+=====================
+PHY Abstraction Layer
+=====================
+
+Purpose
+=======
+
+Most network devices consist of set of registers which provide an interface
+to a MAC layer, which communicates with the physical connection through a
+PHY. The PHY concerns itself with negotiating link parameters with the link
+partner on the other side of the network connection (typically, an ethernet
+cable), and provides a register interface to allow drivers to determine what
+settings were chosen, and to configure what settings are allowed.
+
+While these devices are distinct from the network devices, and conform to a
+standard layout for the registers, it has been common practice to integrate
+the PHY management code with the network driver. This has resulted in large
+amounts of redundant code. Also, on embedded systems with multiple (and
+sometimes quite different) ethernet controllers connected to the same
+management bus, it is difficult to ensure safe use of the bus.
+
+Since the PHYs are devices, and the management busses through which they are
+accessed are, in fact, busses, the PHY Abstraction Layer treats them as such.
+In doing so, it has these goals:
+
+#. Increase code-reuse
+#. Increase overall code-maintainability
+#. Speed development time for new network drivers, and for new systems
+
+Basically, this layer is meant to provide an interface to PHY devices which
+allows network driver writers to write as little code as possible, while
+still providing a full feature set.
+
+The MDIO bus
+============
+
+Most network devices are connected to a PHY by means of a management bus.
+Different devices use different busses (though some share common interfaces).
+In order to take advantage of the PAL, each bus interface needs to be
+registered as a distinct device.
+
+#. read and write functions must be implemented. Their prototypes are::
+
+ int write(struct mii_bus *bus, int mii_id, int regnum, u16 value);
+ int read(struct mii_bus *bus, int mii_id, int regnum);
+
+ mii_id is the address on the bus for the PHY, and regnum is the register
+ number. These functions are guaranteed not to be called from interrupt
+ time, so it is safe for them to block, waiting for an interrupt to signal
+ the operation is complete
+
+#. A reset function is optional. This is used to return the bus to an
+ initialized state.
+
+#. A probe function is needed. This function should set up anything the bus
+ driver needs, setup the mii_bus structure, and register with the PAL using
+ mdiobus_register. Similarly, there's a remove function to undo all of
+ that (use mdiobus_unregister).
+
+#. Like any driver, the device_driver structure must be configured, and init
+ exit functions are used to register the driver.
+
+#. The bus must also be declared somewhere as a device, and registered.
+
+As an example for how one driver implemented an mdio bus driver, see
+drivers/net/ethernet/freescale/fsl_pq_mdio.c and an associated DTS file
+for one of the users. (e.g. "git grep fsl,.*-mdio arch/powerpc/boot/dts/")
+
+(RG)MII/electrical interface considerations
+===========================================
+
+The Reduced Gigabit Medium Independent Interface (RGMII) is a 12-pin
+electrical signal interface using a synchronous 125Mhz clock signal and several
+data lines. Due to this design decision, a 1.5ns to 2ns delay must be added
+between the clock line (RXC or TXC) and the data lines to let the PHY (clock
+sink) have enough setup and hold times to sample the data lines correctly. The
+PHY library offers different types of PHY_INTERFACE_MODE_RGMII* values to let
+the PHY driver and optionally the MAC driver, implement the required delay. The
+values of phy_interface_t must be understood from the perspective of the PHY
+device itself, leading to the following:
+
+* PHY_INTERFACE_MODE_RGMII: the PHY is not responsible for inserting any
+ internal delay by itself, it assumes that either the Ethernet MAC (if capable
+ or the PCB traces) insert the correct 1.5-2ns delay
+
+* PHY_INTERFACE_MODE_RGMII_TXID: the PHY should insert an internal delay
+ for the transmit data lines (TXD[3:0]) processed by the PHY device
+
+* PHY_INTERFACE_MODE_RGMII_RXID: the PHY should insert an internal delay
+ for the receive data lines (RXD[3:0]) processed by the PHY device
+
+* PHY_INTERFACE_MODE_RGMII_ID: the PHY should insert internal delays for
+ both transmit AND receive data lines from/to the PHY device
+
+Whenever possible, use the PHY side RGMII delay for these reasons:
+
+* PHY devices may offer sub-nanosecond granularity in how they allow a
+ receiver/transmitter side delay (e.g: 0.5, 1.0, 1.5ns) to be specified. Such
+ precision may be required to account for differences in PCB trace lengths
+
+* PHY devices are typically qualified for a large range of applications
+ (industrial, medical, automotive...), and they provide a constant and
+ reliable delay across temperature/pressure/voltage ranges
+
+* PHY device drivers in PHYLIB being reusable by nature, being able to
+ configure correctly a specified delay enables more designs with similar delay
+ requirements to be operate correctly
+
+For cases where the PHY is not capable of providing this delay, but the
+Ethernet MAC driver is capable of doing so, the correct phy_interface_t value
+should be PHY_INTERFACE_MODE_RGMII, and the Ethernet MAC driver should be
+configured correctly in order to provide the required transmit and/or receive
+side delay from the perspective of the PHY device. Conversely, if the Ethernet
+MAC driver looks at the phy_interface_t value, for any other mode but
+PHY_INTERFACE_MODE_RGMII, it should make sure that the MAC-level delays are
+disabled.
+
+In case neither the Ethernet MAC, nor the PHY are capable of providing the
+required delays, as defined per the RGMII standard, several options may be
+available:
+
+* Some SoCs may offer a pin pad/mux/controller capable of configuring a given
+ set of pins'strength, delays, and voltage; and it may be a suitable
+ option to insert the expected 2ns RGMII delay.
+
+* Modifying the PCB design to include a fixed delay (e.g: using a specifically
+ designed serpentine), which may not require software configuration at all.
+
+Common problems with RGMII delay mismatch
+-----------------------------------------
+
+When there is a RGMII delay mismatch between the Ethernet MAC and the PHY, this
+will most likely result in the clock and data line signals to be unstable when
+the PHY or MAC take a snapshot of these signals to translate them into logical
+1 or 0 states and reconstruct the data being transmitted/received. Typical
+symptoms include:
+
+* Transmission/reception partially works, and there is frequent or occasional
+ packet loss observed
+
+* Ethernet MAC may report some or all packets ingressing with a FCS/CRC error,
+ or just discard them all
+
+* Switching to lower speeds such as 10/100Mbits/sec makes the problem go away
+ (since there is enough setup/hold time in that case)
+
+Connecting to a PHY
+===================
+
+Sometime during startup, the network driver needs to establish a connection
+between the PHY device, and the network device. At this time, the PHY's bus
+and drivers need to all have been loaded, so it is ready for the connection.
+At this point, there are several ways to connect to the PHY:
+
+#. The PAL handles everything, and only calls the network driver when
+ the link state changes, so it can react.
+
+#. The PAL handles everything except interrupts (usually because the
+ controller has the interrupt registers).
+
+#. The PAL handles everything, but checks in with the driver every second,
+ allowing the network driver to react first to any changes before the PAL
+ does.
+
+#. The PAL serves only as a library of functions, with the network device
+ manually calling functions to update status, and configure the PHY
+
+
+Letting the PHY Abstraction Layer do Everything
+===============================================
+
+If you choose option 1 (The hope is that every driver can, but to still be
+useful to drivers that can't), connecting to the PHY is simple:
+
+First, you need a function to react to changes in the link state. This
+function follows this protocol::
+
+ static void adjust_link(struct net_device *dev);
+
+Next, you need to know the device name of the PHY connected to this device.
+The name will look something like, "0:00", where the first number is the
+bus id, and the second is the PHY's address on that bus. Typically,
+the bus is responsible for making its ID unique.
+
+Now, to connect, just call this function::
+
+ phydev = phy_connect(dev, phy_name, &adjust_link, interface);
+
+*phydev* is a pointer to the phy_device structure which represents the PHY.
+If phy_connect is successful, it will return the pointer. dev, here, is the
+pointer to your net_device. Once done, this function will have started the
+PHY's software state machine, and registered for the PHY's interrupt, if it
+has one. The phydev structure will be populated with information about the
+current state, though the PHY will not yet be truly operational at this
+point.
+
+PHY-specific flags should be set in phydev->dev_flags prior to the call
+to phy_connect() such that the underlying PHY driver can check for flags
+and perform specific operations based on them.
+This is useful if the system has put hardware restrictions on
+the PHY/controller, of which the PHY needs to be aware.
+
+*interface* is a u32 which specifies the connection type used
+between the controller and the PHY. Examples are GMII, MII,
+RGMII, and SGMII. For a full list, see include/linux/phy.h
+
+Now just make sure that phydev->supported and phydev->advertising have any
+values pruned from them which don't make sense for your controller (a 10/100
+controller may be connected to a gigabit capable PHY, so you would need to
+mask off SUPPORTED_1000baseT*). See include/linux/ethtool.h for definitions
+for these bitfields. Note that you should not SET any bits, except the
+SUPPORTED_Pause and SUPPORTED_AsymPause bits (see below), or the PHY may get
+put into an unsupported state.
+
+Lastly, once the controller is ready to handle network traffic, you call
+phy_start(phydev). This tells the PAL that you are ready, and configures the
+PHY to connect to the network. If the MAC interrupt of your network driver
+also handles PHY status changes, just set phydev->irq to PHY_IGNORE_INTERRUPT
+before you call phy_start and use phy_mac_interrupt() from the network
+driver. If you don't want to use interrupts, set phydev->irq to PHY_POLL.
+phy_start() enables the PHY interrupts (if applicable) and starts the
+phylib state machine.
+
+When you want to disconnect from the network (even if just briefly), you call
+phy_stop(phydev). This function also stops the phylib state machine and
+disables PHY interrupts.
+
+Pause frames / flow control
+===========================
+
+The PHY does not participate directly in flow control/pause frames except by
+making sure that the SUPPORTED_Pause and SUPPORTED_AsymPause bits are set in
+MII_ADVERTISE to indicate towards the link partner that the Ethernet MAC
+controller supports such a thing. Since flow control/pause frames generation
+involves the Ethernet MAC driver, it is recommended that this driver takes care
+of properly indicating advertisement and support for such features by setting
+the SUPPORTED_Pause and SUPPORTED_AsymPause bits accordingly. This can be done
+either before or after phy_connect() and/or as a result of implementing the
+ethtool::set_pauseparam feature.
+
+
+Keeping Close Tabs on the PAL
+=============================
+
+It is possible that the PAL's built-in state machine needs a little help to
+keep your network device and the PHY properly in sync. If so, you can
+register a helper function when connecting to the PHY, which will be called
+every second before the state machine reacts to any changes. To do this, you
+need to manually call phy_attach() and phy_prepare_link(), and then call
+phy_start_machine() with the second argument set to point to your special
+handler.
+
+Currently there are no examples of how to use this functionality, and testing
+on it has been limited because the author does not have any drivers which use
+it (they all use option 1). So Caveat Emptor.
+
+Doing it all yourself
+=====================
+
+There's a remote chance that the PAL's built-in state machine cannot track
+the complex interactions between the PHY and your network device. If this is
+so, you can simply call phy_attach(), and not call phy_start_machine or
+phy_prepare_link(). This will mean that phydev->state is entirely yours to
+handle (phy_start and phy_stop toggle between some of the states, so you
+might need to avoid them).
+
+An effort has been made to make sure that useful functionality can be
+accessed without the state-machine running, and most of these functions are
+descended from functions which did not interact with a complex state-machine.
+However, again, no effort has been made so far to test running without the
+state machine, so tryer beware.
+
+Here is a brief rundown of the functions::
+
+ int phy_read(struct phy_device *phydev, u16 regnum);
+ int phy_write(struct phy_device *phydev, u16 regnum, u16 val);
+
+Simple read/write primitives. They invoke the bus's read/write function
+pointers.
+::
+
+ void phy_print_status(struct phy_device *phydev);
+
+A convenience function to print out the PHY status neatly.
+::
+
+ void phy_request_interrupt(struct phy_device *phydev);
+
+Requests the IRQ for the PHY interrupts.
+::
+
+ struct phy_device * phy_attach(struct net_device *dev, const char *phy_id,
+ phy_interface_t interface);
+
+Attaches a network device to a particular PHY, binding the PHY to a generic
+driver if none was found during bus initialization.
+::
+
+ int phy_start_aneg(struct phy_device *phydev);
+
+Using variables inside the phydev structure, either configures advertising
+and resets autonegotiation, or disables autonegotiation, and configures
+forced settings.
+::
+
+ static inline int phy_read_status(struct phy_device *phydev);
+
+Fills the phydev structure with up-to-date information about the current
+settings in the PHY.
+::
+
+ int phy_ethtool_sset(struct phy_device *phydev, struct ethtool_cmd *cmd);
+
+Ethtool convenience functions.
+::
+
+ int phy_mii_ioctl(struct phy_device *phydev,
+ struct mii_ioctl_data *mii_data, int cmd);
+
+The MII ioctl. Note that this function will completely screw up the state
+machine if you write registers like BMCR, BMSR, ADVERTISE, etc. Best to
+use this only to write registers which are not standard, and don't set off
+a renegotiation.
+
+PHY Device Drivers
+==================
+
+With the PHY Abstraction Layer, adding support for new PHYs is
+quite easy. In some cases, no work is required at all! However,
+many PHYs require a little hand-holding to get up-and-running.
+
+Generic PHY driver
+------------------
+
+If the desired PHY doesn't have any errata, quirks, or special
+features you want to support, then it may be best to not add
+support, and let the PHY Abstraction Layer's Generic PHY Driver
+do all of the work.
+
+Writing a PHY driver
+--------------------
+
+If you do need to write a PHY driver, the first thing to do is
+make sure it can be matched with an appropriate PHY device.
+This is done during bus initialization by reading the device's
+UID (stored in registers 2 and 3), then comparing it to each
+driver's phy_id field by ANDing it with each driver's
+phy_id_mask field. Also, it needs a name. Here's an example::
+
+ static struct phy_driver dm9161_driver = {
+ .phy_id = 0x0181b880,
+ .name = "Davicom DM9161E",
+ .phy_id_mask = 0x0ffffff0,
+ ...
+ }
+
+Next, you need to specify what features (speed, duplex, autoneg,
+etc) your PHY device and driver support. Most PHYs support
+PHY_BASIC_FEATURES, but you can look in include/mii.h for other
+features.
+
+Each driver consists of a number of function pointers, documented
+in include/linux/phy.h under the phy_driver structure.
+
+Of these, only config_aneg and read_status are required to be
+assigned by the driver code. The rest are optional. Also, it is
+preferred to use the generic phy driver's versions of these two
+functions if at all possible: genphy_read_status and
+genphy_config_aneg. If this is not possible, it is likely that
+you only need to perform some actions before and after invoking
+these functions, and so your functions will wrap the generic
+ones.
+
+Feel free to look at the Marvell, Cicada, and Davicom drivers in
+drivers/net/phy/ for examples (the lxt and qsemi drivers have
+not been tested as of this writing).
+
+The PHY's MMD register accesses are handled by the PAL framework
+by default, but can be overridden by a specific PHY driver if
+required. This could be the case if a PHY was released for
+manufacturing before the MMD PHY register definitions were
+standardized by the IEEE. Most modern PHYs will be able to use
+the generic PAL framework for accessing the PHY's MMD registers.
+An example of such usage is for Energy Efficient Ethernet support,
+implemented in the PAL. This support uses the PAL to access MMD
+registers for EEE query and configuration if the PHY supports
+the IEEE standard access mechanisms, or can use the PHY's specific
+access interfaces if overridden by the specific PHY driver. See
+the Micrel driver in drivers/net/phy/ for an example of how this
+can be implemented.
+
+Board Fixups
+============
+
+Sometimes the specific interaction between the platform and the PHY requires
+special handling. For instance, to change where the PHY's clock input is,
+or to add a delay to account for latency issues in the data path. In order
+to support such contingencies, the PHY Layer allows platform code to register
+fixups to be run when the PHY is brought up (or subsequently reset).
+
+When the PHY Layer brings up a PHY it checks to see if there are any fixups
+registered for it, matching based on UID (contained in the PHY device's phy_id
+field) and the bus identifier (contained in phydev->dev.bus_id). Both must
+match, however two constants, PHY_ANY_ID and PHY_ANY_UID, are provided as
+wildcards for the bus ID and UID, respectively.
+
+When a match is found, the PHY layer will invoke the run function associated
+with the fixup. This function is passed a pointer to the phy_device of
+interest. It should therefore only operate on that PHY.
+
+The platform code can either register the fixup using phy_register_fixup()::
+
+ int phy_register_fixup(const char *phy_id,
+ u32 phy_uid, u32 phy_uid_mask,
+ int (*run)(struct phy_device *));
+
+Or using one of the two stubs, phy_register_fixup_for_uid() and
+phy_register_fixup_for_id()::
+
+ int phy_register_fixup_for_uid(u32 phy_uid, u32 phy_uid_mask,
+ int (*run)(struct phy_device *));
+ int phy_register_fixup_for_id(const char *phy_id,
+ int (*run)(struct phy_device *));
+
+The stubs set one of the two matching criteria, and set the other one to
+match anything.
+
+When phy_register_fixup() or \*_for_uid()/\*_for_id() is called at module,
+unregister fixup and free allocate memory are required.
+
+Call one of following function before unloading module::
+
+ int phy_unregister_fixup(const char *phy_id, u32 phy_uid, u32 phy_uid_mask);
+ int phy_unregister_fixup_for_uid(u32 phy_uid, u32 phy_uid_mask);
+ int phy_register_fixup_for_id(const char *phy_id);

- receiver/transmitter side delay (e.g: 0.5, 1.0, 1.5ns) to be specified. Such
- precision may be required to account for differences in PCB trace lengths
-
- * PHY devices are typically qualified for a large range of applications
- (industrial, medical, automotive...), and they provide a constant and
- reliable delay across temperature/pressure/voltage ranges
-
- * PHY device drivers in PHYLIB being reusable by nature, being able to
- configure correctly a specified delay enables more designs with similar delay
- requirements to be operate correctly
-
- For cases where the PHY is not capable of providing this delay, but the
- Ethernet MAC driver is capable of doing so, the correct phy_interface_t value
- should be PHY_INTERFACE_MODE_RGMII, and the Ethernet MAC driver should be
- configured correctly in order to provide the required transmit and/or receive
- side delay from the perspective of the PHY device. Conversely, if the Ethernet
- MAC driver looks at the phy_interface_t value, for any other mode but
- PHY_INTERFACE_MODE_RGMII, it should make sure that the MAC-level delays are
- disabled.
-
- In case neither the Ethernet MAC, nor the PHY are capable of providing the
- required delays, as defined per the RGMII standard, several options may be
- available:
-
- * Some SoCs may offer a pin pad/mux/controller capable of configuring a given
- set of pins'strength, delays, and voltage; and it may be a suitable
- option to insert the expected 2ns RGMII delay.
-
- * Modifying the PCB design to include a fixed delay (e.g: using a specifically
- designed serpentine), which may not require software configuration at all.
-
-Common problems with RGMII delay mismatch
-
- When there is a RGMII delay mismatch between the Ethernet MAC and the PHY, this
- will most likely result in the clock and data line signals to be unstable when
- the PHY or MAC take a snapshot of these signals to translate them into logical
- 1 or 0 states and reconstruct the data being transmitted/received. Typical
- symptoms include:
-
- * Transmission/reception partially works, and there is frequent or occasional
- packet loss observed
-
- * Ethernet MAC may report some or all packets ingressing with a FCS/CRC error,
- or just discard them all
-
- * Switching to lower speeds such as 10/100Mbits/sec makes the problem go away
- (since there is enough setup/hold time in that case)
-
-
-Connecting to a PHY
-
- Sometime during startup, the network driver needs to establish a connection
- between the PHY device, and the network device. At this time, the PHY's bus
- and drivers need to all have been loaded, so it is ready for the connection.
- At this point, there are several ways to connect to the PHY:
-
- 1) The PAL handles everything, and only calls the network driver when
- the link state changes, so it can react.
-
- 2) The PAL handles everything except interrupts (usually because the
- controller has the interrupt registers).
-
- 3) The PAL handles everything, but checks in with the driver every second,
- allowing the network driver to react first to any changes before the PAL
- does.
-
- 4) The PAL serves only as a library of functions, with the network device
- manually calling functions to update status, and configure the PHY
-
-
-Letting the PHY Abstraction Layer do Everything
-
- If you choose option 1 (The hope is that every driver can, but to still be
- useful to drivers that can't), connecting to the PHY is simple:
-
- First, you need a function to react to changes in the link state. This
- function follows this protocol:
-
- static void adjust_link(struct net_device *dev);
-
- Next, you need to know the device name of the PHY connected to this device.
- The name will look something like, "0:00", where the first number is the
- bus id, and the second is the PHY's address on that bus. Typically,
- the bus is responsible for making its ID unique.
-
- Now, to connect, just call this function:
-
- phydev = phy_connect(dev, phy_name, &adjust_link, interface);
-
- phydev is a pointer to the phy_device structure which represents the PHY. If
- phy_connect is successful, it will return the pointer. dev, here, is the
- pointer to your net_device. Once done, this function will have started the
- PHY's software state machine, and registered for the PHY's interrupt, if it
- has one. The phydev structure will be populated with information about the
- current state, though the PHY will not yet be truly operational at this
- point.
-
- PHY-specific flags should be set in phydev->dev_flags prior to the call
- to phy_connect() such that the underlying PHY driver can check for flags
- and perform specific operations based on them.
- This is useful if the system has put hardware restrictions on
- the PHY/controller, of which the PHY needs to be aware.
-
- interface is a u32 which specifies the connection type used
- between the controller and the PHY. Examples are GMII, MII,
- RGMII, and SGMII. For a full list, see include/linux/phy.h
-
- Now just make sure that phydev->supported and phydev->advertising have any
- values pruned from them which don't make sense for your controller (a 10/100
- controller may be connected to a gigabit capable PHY, so you would need to
- mask off SUPPORTED_1000baseT*). See include/linux/ethtool.h for definitions
- for these bitfields. Note that you should not SET any bits, except the
- SUPPORTED_Pause and SUPPORTED_AsymPause bits (see below), or the PHY may get
- put into an unsupported state.
-
- Lastly, once the controller is ready to handle network traffic, you call
- phy_start(phydev). This tells the PAL that you are ready, and configures the
- PHY to connect to the network. If you want to handle your own interrupts,
- just set phydev->irq to PHY_IGNORE_INTERRUPT before you call phy_start.
- Similarly, if you don't want to use interrupts, set phydev->irq to PHY_POLL.
-
- When you want to disconnect from the network (even if just briefly), you call
- phy_stop(phydev).
-
-Pause frames / flow control
-
- The PHY does not participate directly in flow control/pause frames except by
- making sure that the SUPPORTED_Pause and SUPPORTED_AsymPause bits are set in
- MII_ADVERTISE to indicate towards the link partner that the Ethernet MAC
- controller supports such a thing. Since flow control/pause frames generation
- involves the Ethernet MAC driver, it is recommended that this driver takes care
- of properly indicating advertisement and support for such features by setting
- the SUPPORTED_Pause and SUPPORTED_AsymPause bits accordingly. This can be done
- either before or after phy_connect() and/or as a result of implementing the
- ethtool::set_pauseparam feature.
-
-
-Keeping Close Tabs on the PAL
-
- It is possible that the PAL's built-in state machine needs a little help to
- keep your network device and the PHY properly in sync. If so, you can
- register a helper function when connecting to the PHY, which will be called
- every second before the state machine reacts to any changes. To do this, you
- need to manually call phy_attach() and phy_prepare_link(), and then call
- phy_start_machine() with the second argument set to point to your special
- handler.
-
- Currently there are no examples of how to use this functionality, and testing
- on it has been limited because the author does not have any drivers which use
- it (they all use option 1). So Caveat Emptor.
-
-Doing it all yourself
-
- There's a remote chance that the PAL's built-in state machine cannot track
- the complex interactions between the PHY and your network device. If this is
- so, you can simply call phy_attach(), and not call phy_start_machine or
- phy_prepare_link(). This will mean that phydev->state is entirely yours to
- handle (phy_start and phy_stop toggle between some of the states, so you
- might need to avoid them).
-
- An effort has been made to make sure that useful functionality can be
- accessed without the state-machine running, and most of these functions are
- descended from functions which did not interact with a complex state-machine.
- However, again, no effort has been made so far to test running without the
- state machine, so tryer beware.
-
- Here is a brief rundown of the functions:
-
- int phy_read(struct phy_device *phydev, u16 regnum);
- int phy_write(struct phy_device *phydev, u16 regnum, u16 val);
-
- Simple read/write primitives. They invoke the bus's read/write function
- pointers.
-
- void phy_print_status(struct phy_device *phydev);
-
- A convenience function to print out the PHY status neatly.
-
- int phy_start_interrupts(struct phy_device *phydev);
- int phy_stop_interrupts(struct phy_device *phydev);
-
- Requests the IRQ for the PHY interrupts, then enables them for
- start, or disables then frees them for stop.
-
- struct phy_device * phy_attach(struct net_device *dev, const char *phy_id,
- phy_interface_t interface);
-
- Attaches a network device to a particular PHY, binding the PHY to a generic
- driver if none was found during bus initialization.
-
- int phy_start_aneg(struct phy_device *phydev);
-
- Using variables inside the phydev structure, either configures advertising
- and resets autonegotiation, or disables autonegotiation, and configures
- forced settings.
-
- static inline int phy_read_status(struct phy_device *phydev);
-
- Fills the phydev structure with up-to-date information about the current
- settings in the PHY.
-
- int phy_ethtool_sset(struct phy_device *phydev, struct ethtool_cmd *cmd);
-
- Ethtool convenience functions.
-
- int phy_mii_ioctl(struct phy_device *phydev,
- struct mii_ioctl_data *mii_data, int cmd);
-
- The MII ioctl. Note that this function will completely screw up the state
- machine if you write registers like BMCR, BMSR, ADVERTISE, etc. Best to
- use this only to write registers which are not standard, and don't set off
- a renegotiation.
-
-
-PHY Device Drivers
-
- With the PHY Abstraction Layer, adding support for new PHYs is
- quite easy. In some cases, no work is required at all! However,
- many PHYs require a little hand-holding to get up-and-running.
-
-Generic PHY driver
-
- If the desired PHY doesn't have any errata, quirks, or special
- features you want to support, then it may be best to not add
- support, and let the PHY Abstraction Layer's Generic PHY Driver
- do all of the work.
-
-Writing a PHY driver
-
- If you do need to write a PHY driver, the first thing to do is
- make sure it can be matched with an appropriate PHY device.
- This is done during bus initialization by reading the device's
- UID (stored in registers 2 and 3), then comparing it to each
- driver's phy_id field by ANDing it with each driver's
- phy_id_mask field. Also, it needs a name. Here's an example:
-
- static struct phy_driver dm9161_driver = {
- .phy_id = 0x0181b880,
- .name = "Davicom DM9161E",
- .phy_id_mask = 0x0ffffff0,
- ...
- }
-
- Next, you need to specify what features (speed, duplex, autoneg,
- etc) your PHY device and driver support. Most PHYs support
- PHY_BASIC_FEATURES, but you can look in include/mii.h for other
- features.
-
- Each driver consists of a number of function pointers, documented
- in include/linux/phy.h under the phy_driver structure.
-
- Of these, only config_aneg and read_status are required to be
- assigned by the driver code. The rest are optional. Also, it is
- preferred to use the generic phy driver's versions of these two
- functions if at all possible: genphy_read_status and
- genphy_config_aneg. If this is not possible, it is likely that
- you only need to perform some actions before and after invoking
- these functions, and so your functions will wrap the generic
- ones.
-
- Feel free to look at the Marvell, Cicada, and Davicom drivers in
- drivers/net/phy/ for examples (the lxt and qsemi drivers have
- not been tested as of this writing).
-
- The PHY's MMD register accesses are handled by the PAL framework
- by default, but can be overridden by a specific PHY driver if
- required. This could be the case if a PHY was released for
- manufacturing before the MMD PHY register definitions were
- standardized by the IEEE. Most modern PHYs will be able to use
- the generic PAL framework for accessing the PHY's MMD registers.
- An example of such usage is for Energy Efficient Ethernet support,
- implemented in the PAL. This support uses the PAL to access MMD
- registers for EEE query and configuration if the PHY supports
- the IEEE standard access mechanisms, or can use the PHY's specific
- access interfaces if overridden by the specific PHY driver. See
- the Micrel driver in drivers/net/phy/ for an example of how this
- can be implemented.
-
-Board Fixups
-
- Sometimes the specific interaction between the platform and the PHY requires
- special handling. For instance, to change where the PHY's clock input is,
- or to add a delay to account for latency issues in the data path. In order
- to support such contingencies, the PHY Layer allows platform code to register
- fixups to be run when the PHY is brought up (or subsequently reset).
-
- When the PHY Layer brings up a PHY it checks to see if there are any fixups
- registered for it, matching based on UID (contained in the PHY device's phy_id
- field) and the bus identifier (contained in phydev->dev.bus_id). Both must
- match, however two constants, PHY_ANY_ID and PHY_ANY_UID, are provided as
- wildcards for the bus ID and UID, respectively.
-
- When a match is found, the PHY layer will invoke the run function associated
- with the fixup. This function is passed a pointer to the phy_device of
- interest. It should therefore only operate on that PHY.
-
- The platform code can either register the fixup using phy_register_fixup():
-
- int phy_register_fixup(const char *phy_id,
- u32 phy_uid, u32 phy_uid_mask,
- int (*run)(struct phy_device *));
-
- Or using one of the two stubs, phy_register_fixup_for_uid() and
- phy_register_fixup_for_id():
-
- int phy_register_fixup_for_uid(u32 phy_uid, u32 phy_uid_mask,
- int (*run)(struct phy_device *));
- int phy_register_fixup_for_id(const char *phy_id,
- int (*run)(struct phy_device *));
-
- The stubs set one of the two matching criteria, and set the other one to
- match anything.
-
- When phy_register_fixup() or *_for_uid()/*_for_id() is called at module,
- unregister fixup and free allocate memory are required.
-
- Call one of following function before unloading module.
-
- int phy_unregister_fixup(const char *phy_id, u32 phy_uid, u32 phy_uid_mask);
- int phy_unregister_fixup_for_uid(u32 phy_uid, u32 phy_uid_mask);
- int phy_register_fixup_for_id(const char *phy_id);

+=====================================
+Scaling in the Linux Networking Stack
+=====================================
+
+
+Introduction
+============
+
+This document describes a set of complementary techniques in the Linux
+networking stack to increase parallelism and improve performance for
+multi-processor systems.
+
+The following technologies are described:
+
+- RSS: Receive Side Scaling
+- RPS: Receive Packet Steering
+- RFS: Receive Flow Steering
+- Accelerated Receive Flow Steering
+- XPS: Transmit Packet Steering
+
+
+RSS: Receive Side Scaling
+=========================
+
+Contemporary NICs support multiple receive and transmit descriptor queues
+(multi-queue). On reception, a NIC can send different packets to different
+queues to distribute processing among CPUs. The NIC distributes packets by
+applying a filter to each packet that assigns it to one of a small number
+of logical flows. Packets for each flow are steered to a separate receive
+queue, which in turn can be processed by separate CPUs. This mechanism is
+generally known as “Receive-side Scaling†(RSS). The goal of RSS and
+the other scaling techniques is to increase performance uniformly.
+Multi-queue distribution can also be used for traffic prioritization, but
+that is not the focus of these techniques.
+
+The filter used in RSS is typically a hash function over the network
+and/or transport layer headers-- for example, a 4-tuple hash over
+IP addresses and TCP ports of a packet. The most common hardware
+implementation of RSS uses a 128-entry indirection table where each entry
+stores a queue number. The receive queue for a packet is determined
+by masking out the low order seven bits of the computed hash for the
+packet (usually a Toeplitz hash), taking this number as a key into the
+indirection table and reading the corresponding value.
+
+Some advanced NICs allow steering packets to queues based on
+programmable filters. For example, webserver bound TCP port 80 packets
+can be directed to their own receive queue. Such “n-tuple†filters can
+be configured from ethtool (--config-ntuple).
+
+
+RSS Configuration
+-----------------
+
+The driver for a multi-queue capable NIC typically provides a kernel
+module parameter for specifying the number of hardware queues to
+configure. In the bnx2x driver, for instance, this parameter is called
+num_queues. A typical RSS configuration would be to have one receive queue
+for each CPU if the device supports enough queues, or otherwise at least
+one for each memory domain, where a memory domain is a set of CPUs that
+share a particular memory level (L1, L2, NUMA node, etc.).
+
+The indirection table of an RSS device, which resolves a queue by masked
+hash, is usually programmed by the driver at initialization. The
+default mapping is to distribute the queues evenly in the table, but the
+indirection table can be retrieved and modified at runtime using ethtool
+commands (--show-rxfh-indir and --set-rxfh-indir). Modifying the
+indirection table could be done to give different queues different
+relative weights.
+
+
+RSS IRQ Configuration
+~~~~~~~~~~~~~~~~~~~~~
+
+Each receive queue has a separate IRQ associated with it. The NIC triggers
+this to notify a CPU when new packets arrive on the given queue. The
+signaling path for PCIe devices uses message signaled interrupts (MSI-X),
+that can route each interrupt to a particular CPU. The active mapping
+of queues to IRQs can be determined from /proc/interrupts. By default,
+an IRQ may be handled on any CPU. Because a non-negligible part of packet
+processing takes place in receive interrupt handling, it is advantageous
+to spread receive interrupts between CPUs. To manually adjust the IRQ
+affinity of each interrupt see Documentation/IRQ-affinity.txt. Some systems
+will be running irqbalance, a daemon that dynamically optimizes IRQ
+assignments and as a result may override any manual settings.
+
+
+Suggested Configuration
+~~~~~~~~~~~~~~~~~~~~~~~
+
+RSS should be enabled when latency is a concern or whenever receive
+interrupt processing forms a bottleneck. Spreading load between CPUs
+decreases queue length. For low latency networking, the optimal setting
+is to allocate as many queues as there are CPUs in the system (or the
+NIC maximum, if lower). The most efficient high-rate configuration
+is likely the one with the smallest number of receive queues where no
+receive queue overflows due to a saturated CPU, because in default
+mode with interrupt coalescing enabled, the aggregate number of
+interrupts (and thus work) grows with each additional queue.
+
+Per-cpu load can be observed using the mpstat utility, but note that on
+processors with hyperthreading (HT), each hyperthread is represented as
+a separate CPU. For interrupt handling, HT has shown no benefit in
+initial tests, so limit the number of queues to the number of CPU cores
+in the system.
+
+
+RPS: Receive Packet Steering
+============================
+
+Receive Packet Steering (RPS) is logically a software implementation of
+RSS. Being in software, it is necessarily called later in the datapath.
+Whereas RSS selects the queue and hence CPU that will run the hardware
+interrupt handler, RPS selects the CPU to perform protocol processing
+above the interrupt handler. This is accomplished by placing the packet
+on the desired CPU’s backlog queue and waking up the CPU for processing.
+RPS has some advantages over RSS:
+
+1) it can be used with any NIC
+2) software filters can easily be added to hash over new protocols
+3) it does not increase hardware device interrupt rate (although it does
+ introduce inter-processor interrupts (IPIs))
+
+RPS is called during bottom half of the receive interrupt handler, when
+a driver sends a packet up the network stack with netif_rx() or
+netif_receive_skb(). These call the get_rps_cpu() function, which
+selects the queue that should process a packet.
+
+The first step in determining the target CPU for RPS is to calculate a
+flow hash over the packet’s addresses or ports (2-tuple or 4-tuple hash
+depending on the protocol). This serves as a consistent hash of the
+associated flow of the packet. The hash is either provided by hardware
+or will be computed in the stack. Capable hardware can pass the hash in
+the receive descriptor for the packet; this would usually be the same
+hash used for RSS (e.g. computed Toeplitz hash). The hash is saved in
+skb->hash and can be used elsewhere in the stack as a hash of the
+packet’s flow.
+
+Each receive hardware queue has an associated list of CPUs to which
+RPS may enqueue packets for processing. For each received packet,
+an index into the list is computed from the flow hash modulo the size
+of the list. The indexed CPU is the target for processing the packet,
+and the packet is queued to the tail of that CPU’s backlog queue. At
+the end of the bottom half routine, IPIs are sent to any CPUs for which
+packets have been queued to their backlog queue. The IPI wakes backlog
+processing on the remote CPU, and any queued packets are then processed
+up the networking stack.
+
+
+RPS Configuration
+-----------------
+
+RPS requires a kernel compiled with the CONFIG_RPS kconfig symbol (on
+by default for SMP). Even when compiled in, RPS remains disabled until
+explicitly configured. The list of CPUs to which RPS may forward traffic
+can be configured for each receive queue using a sysfs file entry::
+
+ /sys/class/net/<dev>/queues/rx-<n>/rps_cpus
+
+This file implements a bitmap of CPUs. RPS is disabled when it is zero
+(the default), in which case packets are processed on the interrupting
+CPU. Documentation/IRQ-affinity.txt explains how CPUs are assigned to
+the bitmap.
+
+
+Suggested Configuration
+~~~~~~~~~~~~~~~~~~~~~~~
+
+For a single queue device, a typical RPS configuration would be to set
+the rps_cpus to the CPUs in the same memory domain of the interrupting
+CPU. If NUMA locality is not an issue, this could also be all CPUs in
+the system. At high interrupt rate, it might be wise to exclude the
+interrupting CPU from the map since that already performs much work.
+
+For a multi-queue system, if RSS is configured so that a hardware
+receive queue is mapped to each CPU, then RPS is probably redundant
+and unnecessary. If there are fewer hardware queues than CPUs, then
+RPS might be beneficial if the rps_cpus for each queue are the ones that
+share the same memory domain as the interrupting CPU for that queue.
+
+
+RPS Flow Limit
+--------------
+
+RPS scales kernel receive processing across CPUs without introducing
+reordering. The trade-off to sending all packets from the same flow
+to the same CPU is CPU load imbalance if flows vary in packet rate.
+In the extreme case a single flow dominates traffic. Especially on
+common server workloads with many concurrent connections, such
+behavior indicates a problem such as a misconfiguration or spoofed
+source Denial of Service attack.
+
+Flow Limit is an optional RPS feature that prioritizes small flows
+during CPU contention by dropping packets from large flows slightly
+ahead of those from small flows. It is active only when an RPS or RFS
+destination CPU approaches saturation. Once a CPU's input packet
+queue exceeds half the maximum queue length (as set by sysctl
+net.core.netdev_max_backlog), the kernel starts a per-flow packet
+count over the last 256 packets. If a flow exceeds a set ratio (by
+default, half) of these packets when a new packet arrives, then the
+new packet is dropped. Packets from other flows are still only
+dropped once the input packet queue reaches netdev_max_backlog.
+No packets are dropped when the input packet queue length is below
+the threshold, so flow limit does not sever connections outright:
+even large flows maintain connectivity.
+
+
+Interface
+~~~~~~~~~
+
+Flow limit is compiled in by default (CONFIG_NET_FLOW_LIMIT), but not
+turned on. It is implemented for each CPU independently (to avoid lock
+and cache contention) and toggled per CPU by setting the relevant bit
+in sysctl net.core.flow_limit_cpu_bitmap. It exposes the same CPU
+bitmap interface as rps_cpus (see above) when called from procfs::
+
+ /proc/sys/net/core/flow_limit_cpu_bitmap
+
+Per-flow rate is calculated by hashing each packet into a hashtable
+bucket and incrementing a per-bucket counter. The hash function is
+the same that selects a CPU in RPS, but as the number of buckets can
+be much larger than the number of CPUs, flow limit has finer-grained
+identification of large flows and fewer false positives. The default
+table has 4096 buckets. This value can be modified through sysctl::
+
+ net.core.flow_limit_table_len
+
+The value is only consulted when a new table is allocated. Modifying
+it does not update active tables.
+
+
+Suggested Configuration
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Flow limit is useful on systems with many concurrent connections,
+where a single connection taking up 50% of a CPU indicates a problem.
+In such environments, enable the feature on all CPUs that handle
+network rx interrupts (as set in /proc/irq/N/smp_affinity).
+
+The feature depends on the input packet queue length to exceed
+the flow limit threshold (50%) + the flow history length (256).
+Setting net.core.netdev_max_backlog to either 1000 or 10000
+performed well in experiments.
+
+
+RFS: Receive Flow Steering
+==========================
+
+While RPS steers packets solely based on hash, and thus generally
+provides good load distribution, it does not take into account
+application locality. This is accomplished by Receive Flow Steering
+(RFS). The goal of RFS is to increase datacache hitrate by steering
+kernel processing of packets to the CPU where the application thread
+consuming the packet is running. RFS relies on the same RPS mechanisms
+to enqueue packets onto the backlog of another CPU and to wake up that
+CPU.
+
+In RFS, packets are not forwarded directly by the value of their hash,
+but the hash is used as index into a flow lookup table. This table maps
+flows to the CPUs where those flows are being processed. The flow hash
+(see RPS section above) is used to calculate the index into this table.
+The CPU recorded in each entry is the one which last processed the flow.
+If an entry does not hold a valid CPU, then packets mapped to that entry
+are steered using plain RPS. Multiple table entries may point to the
+same CPU. Indeed, with many flows and few CPUs, it is very likely that
+a single application thread handles flows with many different flow hashes.
+
+rps_sock_flow_table is a global flow table that contains the *desired* CPU
+for flows: the CPU that is currently processing the flow in userspace.
+Each table value is a CPU index that is updated during calls to recvmsg
+and sendmsg (specifically, inet_recvmsg(), inet_sendmsg(), inet_sendpage()
+and tcp_splice_read()).
+
+When the scheduler moves a thread to a new CPU while it has outstanding
+receive packets on the old CPU, packets may arrive out of order. To
+avoid this, RFS uses a second flow table to track outstanding packets
+for each flow: rps_dev_flow_table is a table specific to each hardware
+receive queue of each device. Each table value stores a CPU index and a
+counter. The CPU index represents the *current* CPU onto which packets
+for this flow are enqueued for further kernel processing. Ideally, kernel
+and userspace processing occur on the same CPU, and hence the CPU index
+in both tables is identical. This is likely false if the scheduler has
+recently migrated a userspace thread while the kernel still has packets
+enqueued for kernel processing on the old CPU.
+
+The counter in rps_dev_flow_table values records the length of the current
+CPU's backlog when a packet in this flow was last enqueued. Each backlog
+queue has a head counter that is incremented on dequeue. A tail counter
+is computed as head counter + queue length. In other words, the counter
+in rps_dev_flow[i] records the last element in flow i that has
+been enqueued onto the currently designated CPU for flow i (of course,
+entry i is actually selected by hash and multiple flows may hash to the
+same entry i).
+
+And now the trick for avoiding out of order packets: when selecting the
+CPU for packet processing (from get_rps_cpu()) the rps_sock_flow table
+and the rps_dev_flow table of the queue that the packet was received on
+are compared. If the desired CPU for the flow (found in the
+rps_sock_flow table) matches the current CPU (found in the rps_dev_flow
+table), the packet is enqueued onto that CPU’s backlog. If they differ,
+the current CPU is updated to match the desired CPU if one of the
+following is true:
+
+ - The current CPU's queue head counter >= the recorded tail counter
+ value in rps_dev_flow[i]
+ - The current CPU is unset (>= nr_cpu_ids)
+ - The current CPU is offline
+
+After this check, the packet is sent to the (possibly updated) current
+CPU. These rules aim to ensure that a flow only moves to a new CPU when
+there are no packets outstanding on the old CPU, as the outstanding
+packets could arrive later than those about to be processed on the new
+CPU.
+
+
+RFS Configuration
+-----------------
+
+RFS is only available if the kconfig symbol CONFIG_RPS is enabled (on
+by default for SMP). The functionality remains disabled until explicitly
+configured. The number of entries in the global flow table is set through::
+
+ /proc/sys/net/core/rps_sock_flow_entries
+
+The number of entries in the per-queue flow table are set through::
+
+ /sys/class/net/<dev>/queues/rx-<n>/rps_flow_cnt
+
+
+Suggested Configuration
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Both of these need to be set before RFS is enabled for a receive queue.
+Values for both are rounded up to the nearest power of two. The
+suggested flow count depends on the expected number of active connections
+at any given time, which may be significantly less than the number of open
+connections. We have found that a value of 32768 for rps_sock_flow_entries
+works fairly well on a moderately loaded server.
+
+For a single queue device, the rps_flow_cnt value for the single queue
+would normally be configured to the same value as rps_sock_flow_entries.
+For a multi-queue device, the rps_flow_cnt for each queue might be
+configured as rps_sock_flow_entries / N, where N is the number of
+queues. So for instance, if rps_sock_flow_entries is set to 32768 and there
+are 16 configured receive queues, rps_flow_cnt for each queue might be
+configured as 2048.
+
+
+Accelerated RFS
+===============
+
+Accelerated RFS is to RFS what RSS is to RPS: a hardware-accelerated load
+balancing mechanism that uses soft state to steer flows based on where
+the application thread consuming the packets of each flow is running.
+Accelerated RFS should perform better than RFS since packets are sent
+directly to a CPU local to the thread consuming the data. The target CPU
+will either be the same CPU where the application runs, or at least a CPU
+which is local to the application thread’s CPU in the cache hierarchy.
+
+To enable accelerated RFS, the networking stack calls the
+ndo_rx_flow_steer driver function to communicate the desired hardware
+queue for packets matching a particular flow. The network stack
+automatically calls this function every time a flow entry in
+rps_dev_flow_table is updated. The driver in turn uses a device specific
+method to program the NIC to steer the packets.
+
+The hardware queue for a flow is derived from the CPU recorded in
+rps_dev_flow_table. The stack consults a CPU to hardware queue map which
+is maintained by the NIC driver. This is an auto-generated reverse map of
+the IRQ affinity table shown by /proc/interrupts. Drivers can use
+functions in the cpu_rmap (“CPU affinity reverse mapâ€) kernel library
+to populate the map. For each CPU, the corresponding queue in the map is
+set to be one whose processing CPU is closest in cache locality.
+
+
+Accelerated RFS Configuration
+-----------------------------
+
+Accelerated RFS is only available if the kernel is compiled with
+CONFIG_RFS_ACCEL and support is provided by the NIC device and driver.
+It also requires that ntuple filtering is enabled via ethtool. The map
+of CPU to queues is automatically deduced from the IRQ affinities
+configured for each receive queue by the driver, so no additional
+configuration should be necessary.
+
+
+Suggested Configuration
+~~~~~~~~~~~~~~~~~~~~~~~
+
+This technique should be enabled whenever one wants to use RFS and the
+NIC supports hardware acceleration.
+
+
+XPS: Transmit Packet Steering
+=============================
+
+Transmit Packet Steering is a mechanism for intelligently selecting
+which transmit queue to use when transmitting a packet on a multi-queue
+device. This can be accomplished by recording two kinds of maps, either
+a mapping of CPU to hardware queue(s) or a mapping of receive queue(s)
+to hardware transmit queue(s).
+
+1. XPS using CPUs map
+
+The goal of this mapping is usually to assign queues
+exclusively to a subset of CPUs, where the transmit completions for
+these queues are processed on a CPU within this set. This choice
+provides two benefits. First, contention on the device queue lock is
+significantly reduced since fewer CPUs contend for the same queue
+(contention can be eliminated completely if each CPU has its own
+transmit queue). Secondly, cache miss rate on transmit completion is
+reduced, in particular for data cache lines that hold the sk_buff
+structures.
+
+2. XPS using receive queues map
+
+This mapping is used to pick transmit queue based on the receive
+queue(s) map configuration set by the administrator. A set of receive
+queues can be mapped to a set of transmit queues (many:many), although
+the common use case is a 1:1 mapping. This will enable sending packets
+on the same queue associations for transmit and receive. This is useful for
+busy polling multi-threaded workloads where there are challenges in
+associating a given CPU to a given application thread. The application
+threads are not pinned to CPUs and each thread handles packets
+received on a single queue. The receive queue number is cached in the
+socket for the connection. In this model, sending the packets on the same
+transmit queue corresponding to the associated receive queue has benefits
+in keeping the CPU overhead low. Transmit completion work is locked into
+the same queue-association that a given application is polling on. This
+avoids the overhead of triggering an interrupt on another CPU. When the
+application cleans up the packets during the busy poll, transmit completion
+may be processed along with it in the same thread context and so result in
+reduced latency.
+
+XPS is configured per transmit queue by setting a bitmap of
+CPUs/receive-queues that may use that queue to transmit. The reverse
+mapping, from CPUs to transmit queues or from receive-queues to transmit
+queues, is computed and maintained for each network device. When
+transmitting the first packet in a flow, the function get_xps_queue() is
+called to select a queue. This function uses the ID of the receive queue
+for the socket connection for a match in the receive queue-to-transmit queue
+lookup table. Alternatively, this function can also use the ID of the
+running CPU as a key into the CPU-to-queue lookup table. If the
+ID matches a single queue, that is used for transmission. If multiple
+queues match, one is selected by using the flow hash to compute an index
+into the set. When selecting the transmit queue based on receive queue(s)
+map, the transmit device is not validated against the receive device as it
+requires expensive lookup operation in the datapath.
+
+The queue chosen for transmitting a particular flow is saved in the
+corresponding socket structure for the flow (e.g. a TCP connection).
+This transmit queue is used for subsequent packets sent on the flow to
+prevent out of order (ooo) packets. The choice also amortizes the cost
+of calling get_xps_queues() over all packets in the flow. To avoid
+ooo packets, the queue for a flow can subsequently only be changed if
+skb->ooo_okay is set for a packet in the flow. This flag indicates that
+there are no outstanding packets in the flow, so the transmit queue can
+change without the risk of generating out of order packets. The
+transport layer is responsible for setting ooo_okay appropriately. TCP,
+for instance, sets the flag when all data for a connection has been
+acknowledged.
+
+XPS Configuration
+-----------------
+
+XPS is only available if the kconfig symbol CONFIG_XPS is enabled (on by
+default for SMP). The functionality remains disabled until explicitly
+configured. To enable XPS, the bitmap of CPUs/receive-queues that may
+use a transmit queue is configured using the sysfs file entry:
+
+For selection based on CPUs map::
+
+ /sys/class/net/<dev>/queues/tx-<n>/xps_cpus
+
+For selection based on receive-queues map::
+
+ /sys/class/net/<dev>/queues/tx-<n>/xps_rxqs
+
+
+Suggested Configuration
+~~~~~~~~~~~~~~~~~~~~~~~
+
+For a network device with a single transmission queue, XPS configuration
+has no effect, since there is no choice in this case. In a multi-queue
+system, XPS is preferably configured so that each CPU maps onto one queue.
+If there are as many queues as there are CPUs in the system, then each
+queue can also map onto one CPU, resulting in exclusive pairings that
+experience no contention. If there are fewer queues than CPUs, then the
+best CPUs to share a given queue are probably those that share the cache
+with the CPU that processes transmit completions for that queue
+(transmit interrupts).
+
+For transmit queue selection based on receive queue(s), XPS has to be
+explicitly configured mapping receive-queue(s) to transmit queue(s). If the
+user configuration for receive-queue map does not apply, then the transmit
+queue is selected based on the CPUs map.
+
+
+Per TX Queue rate limitation
+============================
+
+These are rate-limitation mechanisms implemented by HW, where currently
+a max-rate attribute is supported, by setting a Mbps value to::
+
+ /sys/class/net/<dev>/queues/tx-<n>/tx_maxrate
+
+A value of zero means disabled, and this is the default.
+

-Scaling in the Linux Networking Stack

-
-Introduction
-============
-
-This document describes a set of complementary techniques in the Linux
-networking stack to increase parallelism and improve performance for
-multi-processor systems.
-
-The following technologies are described:
-
- RSS: Receive Side Scaling
- RPS: Receive Packet Steering
- RFS: Receive Flow Steering
- Accelerated Receive Flow Steering
- XPS: Transmit Packet Steering
-
-
-RSS: Receive Side Scaling
-=========================
-
-Contemporary NICs support multiple receive and transmit descriptor queues
-(multi-queue). On reception, a NIC can send different packets to different
-queues to distribute processing among CPUs. The NIC distributes packets by
-applying a filter to each packet that assigns it to one of a small number
-of logical flows. Packets for each flow are steered to a separate receive
-queue, which in turn can be processed by separate CPUs. This mechanism is
-generally known as “Receive-side Scaling†(RSS). The goal of RSS and
-the other scaling techniques is to increase performance uniformly.
-Multi-queue distribution can also be used for traffic prioritization, but
-that is not the focus of these techniques.
-
-The filter used in RSS is typically a hash function over the network
-and/or transport layer headers-- for example, a 4-tuple hash over
-IP addresses and TCP ports of a packet. The most common hardware
-implementation of RSS uses a 128-entry indirection table where each entry
-stores a queue number. The receive queue for a packet is determined
-by masking out the low order seven bits of the computed hash for the
-packet (usually a Toeplitz hash), taking this number as a key into the
-indirection table and reading the corresponding value.
-
-Some advanced NICs allow steering packets to queues based on
-programmable filters. For example, webserver bound TCP port 80 packets
-can be directed to their own receive queue. Such “n-tuple†filters can
-be configured from ethtool (--config-ntuple).
-
-==== RSS Configuration
-
-The driver for a multi-queue capable NIC typically provides a kernel
-module parameter for specifying the number of hardware queues to
-configure. In the bnx2x driver, for instance, this parameter is called
-num_queues. A typical RSS configuration would be to have one receive queue
-for each CPU if the device supports enough queues, or otherwise at least
-one for each memory domain, where a memory domain is a set of CPUs that
-share a particular memory level (L1, L2, NUMA node, etc.).
-
-The indirection table of an RSS device, which resolves a queue by masked
-hash, is usually programmed by the driver at initialization. The
-default mapping is to distribute the queues evenly in the table, but the
-indirection table can be retrieved and modified at runtime using ethtool
-commands (--show-rxfh-indir and --set-rxfh-indir). Modifying the
-indirection table could be done to give different queues different
-relative weights.
-
-== RSS IRQ Configuration
-
-Each receive queue has a separate IRQ associated with it. The NIC triggers
-this to notify a CPU when new packets arrive on the given queue. The
-signaling path for PCIe devices uses message signaled interrupts (MSI-X),
-that can route each interrupt to a particular CPU. The active mapping
-of queues to IRQs can be determined from /proc/interrupts. By default,
-an IRQ may be handled on any CPU. Because a non-negligible part of packet
-processing takes place in receive interrupt handling, it is advantageous
-to spread receive interrupts between CPUs. To manually adjust the IRQ
-affinity of each interrupt see Documentation/IRQ-affinity.txt. Some systems
-will be running irqbalance, a daemon that dynamically optimizes IRQ
-assignments and as a result may override any manual settings.
-
-== Suggested Configuration
-
-RSS should be enabled when latency is a concern or whenever receive
-interrupt processing forms a bottleneck. Spreading load between CPUs
-decreases queue length. For low latency networking, the optimal setting
-is to allocate as many queues as there are CPUs in the system (or the
-NIC maximum, if lower). The most efficient high-rate configuration
-is likely the one with the smallest number of receive queues where no
-receive queue overflows due to a saturated CPU, because in default
-mode with interrupt coalescing enabled, the aggregate number of
-interrupts (and thus work) grows with each additional queue.
-
-Per-cpu load can be observed using the mpstat utility, but note that on
-processors with hyperthreading (HT), each hyperthread is represented as
-a separate CPU. For interrupt handling, HT has shown no benefit in
-initial tests, so limit the number of queues to the number of CPU cores
-in the system.
-
-
-RPS: Receive Packet Steering
-============================
-
-Receive Packet Steering (RPS) is logically a software implementation of
-RSS. Being in software, it is necessarily called later in the datapath.
-Whereas RSS selects the queue and hence CPU that will run the hardware
-interrupt handler, RPS selects the CPU to perform protocol processing
-above the interrupt handler. This is accomplished by placing the packet
-on the desired CPU’s backlog queue and waking up the CPU for processing.
-RPS has some advantages over RSS: 1) it can be used with any NIC,
-2) software filters can easily be added to hash over new protocols,
-3) it does not increase hardware device interrupt rate (although it does
-introduce inter-processor interrupts (IPIs)).
-
-RPS is called during bottom half of the receive interrupt handler, when
-a driver sends a packet up the network stack with netif_rx() or
-netif_receive_skb(). These call the get_rps_cpu() function, which
-selects the queue that should process a packet.
-
-The first step in determining the target CPU for RPS is to calculate a
-flow hash over the packet’s addresses or ports (2-tuple or 4-tuple hash
-depending on the protocol). This serves as a consistent hash of the
-associated flow of the packet. The hash is either provided by hardware
-or will be computed in the stack. Capable hardware can pass the hash in
-the receive descriptor for the packet; this would usually be the same
-hash used for RSS (e.g. computed Toeplitz hash). The hash is saved in
-skb->hash and can be used elsewhere in the stack as a hash of the
-packet’s flow.
-
-Each receive hardware queue has an associated list of CPUs to which
-RPS may enqueue packets for processing. For each received packet,
-an index into the list is computed from the flow hash modulo the size
-of the list. The indexed CPU is the target for processing the packet,
-and the packet is queued to the tail of that CPU’s backlog queue. At
-the end of the bottom half routine, IPIs are sent to any CPUs for which
-packets have been queued to their backlog queue. The IPI wakes backlog
-processing on the remote CPU, and any queued packets are then processed
-up the networking stack.
-
-==== RPS Configuration
-
-RPS requires a kernel compiled with the CONFIG_RPS kconfig symbol (on
-by default for SMP). Even when compiled in, RPS remains disabled until
-explicitly configured. The list of CPUs to which RPS may forward traffic
-can be configured for each receive queue using a sysfs file entry:
-
- /sys/class/net/<dev>/queues/rx-<n>/rps_cpus
-
-This file implements a bitmap of CPUs. RPS is disabled when it is zero
-(the default), in which case packets are processed on the interrupting
-CPU. Documentation/IRQ-affinity.txt explains how CPUs are assigned to
-the bitmap.
-
-== Suggested Configuration
-
-For a single queue device, a typical RPS configuration would be to set
-the rps_cpus to the CPUs in the same memory domain of the interrupting
-CPU. If NUMA locality is not an issue, this could also be all CPUs in
-the system. At high interrupt rate, it might be wise to exclude the
-interrupting CPU from the map since that already performs much work.
-
-For a multi-queue system, if RSS is configured so that a hardware
-receive queue is mapped to each CPU, then RPS is probably redundant
-and unnecessary. If there are fewer hardware queues than CPUs, then
-RPS might be beneficial if the rps_cpus for each queue are the ones that
-share the same memory domain as the interrupting CPU for that queue.
-
-==== RPS Flow Limit
-
-RPS scales kernel receive processing across CPUs without introducing
-reordering. The trade-off to sending all packets from the same flow
-to the same CPU is CPU load imbalance if flows vary in packet rate.
-In the extreme case a single flow dominates traffic. Especially on
-common server workloads with many concurrent connections, such
-behavior indicates a problem such as a misconfiguration or spoofed
-source Denial of Service attack.
-
-Flow Limit is an optional RPS feature that prioritizes small flows
-during CPU contention by dropping packets from large flows slightly
-ahead of those from small flows. It is active only when an RPS or RFS
-destination CPU approaches saturation. Once a CPU's input packet
-queue exceeds half the maximum queue length (as set by sysctl
-net.core.netdev_max_backlog), the kernel starts a per-flow packet
-count over the last 256 packets. If a flow exceeds a set ratio (by
-default, half) of these packets when a new packet arrives, then the
-new packet is dropped. Packets from other flows are still only
-dropped once the input packet queue reaches netdev_max_backlog.
-No packets are dropped when the input packet queue length is below
-the threshold, so flow limit does not sever connections outright:
-even large flows maintain connectivity.
-
-== Interface
-
-Flow limit is compiled in by default (CONFIG_NET_FLOW_LIMIT), but not
-turned on. It is implemented for each CPU independently (to avoid lock
-and cache contention) and toggled per CPU by setting the relevant bit
-in sysctl net.core.flow_limit_cpu_bitmap. It exposes the same CPU
-bitmap interface as rps_cpus (see above) when called from procfs:
-
- /proc/sys/net/core/flow_limit_cpu_bitmap
-
-Per-flow rate is calculated by hashing each packet into a hashtable
-bucket and incrementing a per-bucket counter. The hash function is
-the same that selects a CPU in RPS, but as the number of buckets can
-be much larger than the number of CPUs, flow limit has finer-grained
-identification of large flows and fewer false positives. The default
-table has 4096 buckets. This value can be modified through sysctl
-
- net.core.flow_limit_table_len
-
-The value is only consulted when a new table is allocated. Modifying
-it does not update active tables.
-
-== Suggested Configuration
-
-Flow limit is useful on systems with many concurrent connections,
-where a single connection taking up 50% of a CPU indicates a problem.
-In such environments, enable the feature on all CPUs that handle
-network rx interrupts (as set in /proc/irq/N/smp_affinity).
-
-The feature depends on the input packet queue length to exceed
-the flow limit threshold (50%) + the flow history length (256).
-Setting net.core.netdev_max_backlog to either 1000 or 10000
-performed well in experiments.
-
-
-RFS: Receive Flow Steering
-==========================
-
-While RPS steers packets solely based on hash, and thus generally
-provides good load distribution, it does not take into account
-application locality. This is accomplished by Receive Flow Steering
-(RFS). The goal of RFS is to increase datacache hitrate by steering
-kernel processing of packets to the CPU where the application thread
-consuming the packet is running. RFS relies on the same RPS mechanisms
-to enqueue packets onto the backlog of another CPU and to wake up that
-CPU.
-
-In RFS, packets are not forwarded directly by the value of their hash,
-but the hash is used as index into a flow lookup table. This table maps
-flows to the CPUs where those flows are being processed. The flow hash
-(see RPS section above) is used to calculate the index into this table.
-The CPU recorded in each entry is the one which last processed the flow.
-If an entry does not hold a valid CPU, then packets mapped to that entry
-are steered using plain RPS. Multiple table entries may point to the
-same CPU. Indeed, with many flows and few CPUs, it is very likely that
-a single application thread handles flows with many different flow hashes.
-
-rps_sock_flow_table is a global flow table that contains the *desired* CPU
-for flows: the CPU that is currently processing the flow in userspace.
-Each table value is a CPU index that is updated during calls to recvmsg
-and sendmsg (specifically, inet_recvmsg(), inet_sendmsg(), inet_sendpage()
-and tcp_splice_read()).
-
-When the scheduler moves a thread to a new CPU while it has outstanding
-receive packets on the old CPU, packets may arrive out of order. To
-avoid this, RFS uses a second flow table to track outstanding packets
-for each flow: rps_dev_flow_table is a table specific to each hardware
-receive queue of each device. Each table value stores a CPU index and a
-counter. The CPU index represents the *current* CPU onto which packets
-for this flow are enqueued for further kernel processing. Ideally, kernel
-and userspace processing occur on the same CPU, and hence the CPU index
-in both tables is identical. This is likely false if the scheduler has
-recently migrated a userspace thread while the kernel still has packets
-enqueued for kernel processing on the old CPU.
-
-The counter in rps_dev_flow_table values records the length of the current
-CPU's backlog when a packet in this flow was last enqueued. Each backlog
-queue has a head counter that is incremented on dequeue. A tail counter
-is computed as head counter + queue length. In other words, the counter
-in rps_dev_flow[i] records the last element in flow i that has
-been enqueued onto the currently designated CPU for flow i (of course,
-entry i is actually selected by hash and multiple flows may hash to the
-same entry i).
-
-And now the trick for avoiding out of order packets: when selecting the
-CPU for packet processing (from get_rps_cpu()) the rps_sock_flow table
-and the rps_dev_flow table of the queue that the packet was received on
-are compared. If the desired CPU for the flow (found in the
-rps_sock_flow table) matches the current CPU (found in the rps_dev_flow
-table), the packet is enqueued onto that CPU’s backlog. If they differ,
-the current CPU is updated to match the desired CPU if one of the
-following is true:
-
-- The current CPU's queue head counter >= the recorded tail counter
- value in rps_dev_flow[i]
-- The current CPU is unset (>= nr_cpu_ids)
-- The current CPU is offline
-
-After this check, the packet is sent to the (possibly updated) current
-CPU. These rules aim to ensure that a flow only moves to a new CPU when
-there are no packets outstanding on the old CPU, as the outstanding
-packets could arrive later than those about to be processed on the new
-CPU.
-
-==== RFS Configuration
-
-RFS is only available if the kconfig symbol CONFIG_RPS is enabled (on
-by default for SMP). The functionality remains disabled until explicitly
-configured. The number of entries in the global flow table is set through:
-
- /proc/sys/net/core/rps_sock_flow_entries
-
-The number of entries in the per-queue flow table are set through:
-
- /sys/class/net/<dev>/queues/rx-<n>/rps_flow_cnt
-
-== Suggested Configuration
-
-Both of these need to be set before RFS is enabled for a receive queue.
-Values for both are rounded up to the nearest power of two. The
-suggested flow count depends on the expected number of active connections
-at any given time, which may be significantly less than the number of open
-connections. We have found that a value of 32768 for rps_sock_flow_entries
-works fairly well on a moderately loaded server.
-
-For a single queue device, the rps_flow_cnt value for the single queue
-would normally be configured to the same value as rps_sock_flow_entries.
-For a multi-queue device, the rps_flow_cnt for each queue might be
-configured as rps_sock_flow_entries / N, where N is the number of
-queues. So for instance, if rps_sock_flow_entries is set to 32768 and there
-are 16 configured receive queues, rps_flow_cnt for each queue might be
-configured as 2048.
-
-
-Accelerated RFS
-===============
-
-Accelerated RFS is to RFS what RSS is to RPS: a hardware-accelerated load
-balancing mechanism that uses soft state to steer flows based on where
-the application thread consuming the packets of each flow is running.
-Accelerated RFS should perform better than RFS since packets are sent
-directly to a CPU local to the thread consuming the data. The target CPU
-will either be the same CPU where the application runs, or at least a CPU
-which is local to the application thread’s CPU in the cache hierarchy.
-
-To enable accelerated RFS, the networking stack calls the
-ndo_rx_flow_steer driver function to communicate the desired hardware
-queue for packets matching a particular flow. The network stack
-automatically calls this function every time a flow entry in
-rps_dev_flow_table is updated. The driver in turn uses a device specific
-method to program the NIC to steer the packets.
-
-The hardware queue for a flow is derived from the CPU recorded in
-rps_dev_flow_table. The stack consults a CPU to hardware queue map which
-is maintained by the NIC driver. This is an auto-generated reverse map of
-the IRQ affinity table shown by /proc/interrupts. Drivers can use
-functions in the cpu_rmap (“CPU affinity reverse mapâ€) kernel library
-to populate the map. For each CPU, the corresponding queue in the map is
-set to be one whose processing CPU is closest in cache locality.
-
-==== Accelerated RFS Configuration
-
-Accelerated RFS is only available if the kernel is compiled with
-CONFIG_RFS_ACCEL and support is provided by the NIC device and driver.
-It also requires that ntuple filtering is enabled via ethtool. The map
-of CPU to queues is automatically deduced from the IRQ affinities
-configured for each receive queue by the driver, so no additional
-configuration should be necessary.
-
-== Suggested Configuration
-
-This technique should be enabled whenever one wants to use RFS and the
-NIC supports hardware acceleration.
-
-XPS: Transmit Packet Steering
-=============================
-
-Transmit Packet Steering is a mechanism for intelligently selecting
-which transmit queue to use when transmitting a packet on a multi-queue
-device. This can be accomplished by recording two kinds of maps, either
-a mapping of CPU to hardware queue(s) or a mapping of receive queue(s)
-to hardware transmit queue(s).
-
-1. XPS using CPUs map
-
-The goal of this mapping is usually to assign queues
-exclusively to a subset of CPUs, where the transmit completions for
-these queues are processed on a CPU within this set. This choice
-provides two benefits. First, contention on the device queue lock is
-significantly reduced since fewer CPUs contend for the same queue
-(contention can be eliminated completely if each CPU has its own
-transmit queue). Secondly, cache miss rate on transmit completion is
-reduced, in particular for data cache lines that hold the sk_buff
-structures.
-
-2. XPS using receive queues map
-
-This mapping is used to pick transmit queue based on the receive
-queue(s) map configuration set by the administrator. A set of receive
-queues can be mapped to a set of transmit queues (many:many), although
-the common use case is a 1:1 mapping. This will enable sending packets
-on the same queue associations for transmit and receive. This is useful for
-busy polling multi-threaded workloads where there are challenges in
-associating a given CPU to a given application thread. The application
-threads are not pinned to CPUs and each thread handles packets
-received on a single queue. The receive queue number is cached in the
-socket for the connection. In this model, sending the packets on the same
-transmit queue corresponding to the associated receive queue has benefits
-in keeping the CPU overhead low. Transmit completion work is locked into
-the same queue-association that a given application is polling on. This
-avoids the overhead of triggering an interrupt on another CPU. When the
-application cleans up the packets during the busy poll, transmit completion
-may be processed along with it in the same thread context and so result in
-reduced latency.
-
-XPS is configured per transmit queue by setting a bitmap of
-CPUs/receive-queues that may use that queue to transmit. The reverse
-mapping, from CPUs to transmit queues or from receive-queues to transmit
-queues, is computed and maintained for each network device. When
-transmitting the first packet in a flow, the function get_xps_queue() is
-called to select a queue. This function uses the ID of the receive queue
-for the socket connection for a match in the receive queue-to-transmit queue
-lookup table. Alternatively, this function can also use the ID of the
-running CPU as a key into the CPU-to-queue lookup table. If the
-ID matches a single queue, that is used for transmission. If multiple
-queues match, one is selected by using the flow hash to compute an index
-into the set. When selecting the transmit queue based on receive queue(s)
-map, the transmit device is not validated against the receive device as it
-requires expensive lookup operation in the datapath.
-
-The queue chosen for transmitting a particular flow is saved in the
-corresponding socket structure for the flow (e.g. a TCP connection).
-This transmit queue is used for subsequent packets sent on the flow to
-prevent out of order (ooo) packets. The choice also amortizes the cost
-of calling get_xps_queues() over all packets in the flow. To avoid
-ooo packets, the queue for a flow can subsequently only be changed if
-skb->ooo_okay is set for a packet in the flow. This flag indicates that
-there are no outstanding packets in the flow, so the transmit queue can
-change without the risk of generating out of order packets. The
-transport layer is responsible for setting ooo_okay appropriately. TCP,
-for instance, sets the flag when all data for a connection has been
-acknowledged.
-
-==== XPS Configuration
-
-XPS is only available if the kconfig symbol CONFIG_XPS is enabled (on by
-default for SMP). The functionality remains disabled until explicitly
-configured. To enable XPS, the bitmap of CPUs/receive-queues that may
-use a transmit queue is configured using the sysfs file entry:
-
-For selection based on CPUs map:
-/sys/class/net/<dev>/queues/tx-<n>/xps_cpus
-
-For selection based on receive-queues map:
-/sys/class/net/<dev>/queues/tx-<n>/xps_rxqs
-
-== Suggested Configuration
-
-For a network device with a single transmission queue, XPS configuration
-has no effect, since there is no choice in this case. In a multi-queue
-system, XPS is preferably configured so that each CPU maps onto one queue.
-If there are as many queues as there are CPUs in the system, then each
-queue can also map onto one CPU, resulting in exclusive pairings that
-experience no contention. If there are fewer queues than CPUs, then the
-best CPUs to share a given queue are probably those that share the cache
-with the CPU that processes transmit completions for that queue
-(transmit interrupts).
-
-For transmit queue selection based on receive queue(s), XPS has to be
-explicitly configured mapping receive-queue(s) to transmit queue(s). If the
-user configuration for receive-queue map does not apply, then the transmit
-queue is selected based on the CPUs map.
-
-Per TX Queue rate limitation:
-=============================
-
-These are rate-limitation mechanisms implemented by HW, where currently
-a max-rate attribute is supported, by setting a Mbps value to
-
-/sys/class/net/<dev>/queues/tx-<n>/tx_maxrate
-
-A value of zero means disabled, and this is the default.
-

+Segmentation Offloads
+=====================
+
+
+Introduction
+============
+
+This document describes a set of techniques in the Linux networking stack
+to take advantage of segmentation offload capabilities of various NICs.
+
+The following technologies are described:
+ * TCP Segmentation Offload - TSO
+ * UDP Fragmentation Offload - UFO
+ * IPIP, SIT, GRE, and UDP Tunnel Offloads
+ * Generic Segmentation Offload - GSO
+ * Generic Receive Offload - GRO
+ * Partial Generic Segmentation Offload - GSO_PARTIAL
+ * SCTP accelleration with GSO - GSO_BY_FRAGS
+
+
+TCP Segmentation Offload
+========================
+
+TCP segmentation allows a device to segment a single frame into multiple
+frames with a data payload size specified in skb_shinfo()->gso_size.
+When TCP segmentation requested the bit for either SKB_GSO_TCPV4 or
+SKB_GSO_TCPV6 should be set in skb_shinfo()->gso_type and
+skb_shinfo()->gso_size should be set to a non-zero value.
+
+TCP segmentation is dependent on support for the use of partial checksum
+offload. For this reason TSO is normally disabled if the Tx checksum
+offload for a given device is disabled.
+
+In order to support TCP segmentation offload it is necessary to populate
+the network and transport header offsets of the skbuff so that the device
+drivers will be able determine the offsets of the IP or IPv6 header and the
+TCP header. In addition as CHECKSUM_PARTIAL is required csum_start should
+also point to the TCP header of the packet.
+
+For IPv4 segmentation we support one of two types in terms of the IP ID.
+The default behavior is to increment the IP ID with every segment. If the
+GSO type SKB_GSO_TCP_FIXEDID is specified then we will not increment the IP
+ID and all segments will use the same IP ID. If a device has
+NETIF_F_TSO_MANGLEID set then the IP ID can be ignored when performing TSO
+and we will either increment the IP ID for all frames, or leave it at a
+static value based on driver preference.
+
+
+UDP Fragmentation Offload
+=========================
+
+UDP fragmentation offload allows a device to fragment an oversized UDP
+datagram into multiple IPv4 fragments. Many of the requirements for UDP
+fragmentation offload are the same as TSO. However the IPv4 ID for
+fragments should not increment as a single IPv4 datagram is fragmented.
+
+UFO is deprecated: modern kernels will no longer generate UFO skbs, but can
+still receive them from tuntap and similar devices. Offload of UDP-based
+tunnel protocols is still supported.
+
+
+IPIP, SIT, GRE, UDP Tunnel, and Remote Checksum Offloads
+========================================================
+
+In addition to the offloads described above it is possible for a frame to
+contain additional headers such as an outer tunnel. In order to account
+for such instances an additional set of segmentation offload types were
+introduced including SKB_GSO_IPXIP4, SKB_GSO_IPXIP6, SKB_GSO_GRE, and
+SKB_GSO_UDP_TUNNEL. These extra segmentation types are used to identify
+cases where there are more than just 1 set of headers. For example in the
+case of IPIP and SIT we should have the network and transport headers moved
+from the standard list of headers to "inner" header offsets.
+
+Currently only two levels of headers are supported. The convention is to
+refer to the tunnel headers as the outer headers, while the encapsulated
+data is normally referred to as the inner headers. Below is the list of
+calls to access the given headers:
+
+IPIP/SIT Tunnel::
+
+ Outer Inner
+ MAC skb_mac_header
+ Network skb_network_header skb_inner_network_header
+ Transport skb_transport_header
+
+UDP/GRE Tunnel::
+
+ Outer Inner
+ MAC skb_mac_header skb_inner_mac_header
+ Network skb_network_header skb_inner_network_header
+ Transport skb_transport_header skb_inner_transport_header
+
+In addition to the above tunnel types there are also SKB_GSO_GRE_CSUM and
+SKB_GSO_UDP_TUNNEL_CSUM. These two additional tunnel types reflect the
+fact that the outer header also requests to have a non-zero checksum
+included in the outer header.
+
+Finally there is SKB_GSO_TUNNEL_REMCSUM which indicates that a given tunnel
+header has requested a remote checksum offload. In this case the inner
+headers will be left with a partial checksum and only the outer header
+checksum will be computed.
+
+
+Generic Segmentation Offload
+============================
+
+Generic segmentation offload is a pure software offload that is meant to
+deal with cases where device drivers cannot perform the offloads described
+above. What occurs in GSO is that a given skbuff will have its data broken
+out over multiple skbuffs that have been resized to match the MSS provided
+via skb_shinfo()->gso_size.
+
+Before enabling any hardware segmentation offload a corresponding software
+offload is required in GSO. Otherwise it becomes possible for a frame to
+be re-routed between devices and end up being unable to be transmitted.
+
+
+Generic Receive Offload
+=======================
+
+Generic receive offload is the complement to GSO. Ideally any frame
+assembled by GRO should be segmented to create an identical sequence of
+frames using GSO, and any sequence of frames segmented by GSO should be
+able to be reassembled back to the original by GRO. The only exception to
+this is IPv4 ID in the case that the DF bit is set for a given IP header.
+If the value of the IPv4 ID is not sequentially incrementing it will be
+altered so that it is when a frame assembled via GRO is segmented via GSO.
+
+
+Partial Generic Segmentation Offload
+====================================
+
+Partial generic segmentation offload is a hybrid between TSO and GSO. What
+it effectively does is take advantage of certain traits of TCP and tunnels
+so that instead of having to rewrite the packet headers for each segment
+only the inner-most transport header and possibly the outer-most network
+header need to be updated. This allows devices that do not support tunnel
+offloads or tunnel offloads with checksum to still make use of segmentation.
+
+With the partial offload what occurs is that all headers excluding the
+inner transport header are updated such that they will contain the correct
+values for if the header was simply duplicated. The one exception to this
+is the outer IPv4 ID field. It is up to the device drivers to guarantee
+that the IPv4 ID field is incremented in the case that a given header does
+not have the DF bit set.
+
+
+SCTP accelleration with GSO
+===========================
+
+SCTP - despite the lack of hardware support - can still take advantage of
+GSO to pass one large packet through the network stack, rather than
+multiple small packets.
+
+This requires a different approach to other offloads, as SCTP packets
+cannot be just segmented to (P)MTU. Rather, the chunks must be contained in
+IP segments, padding respected. So unlike regular GSO, SCTP can't just
+generate a big skb, set gso_size to the fragmentation point and deliver it
+to IP layer.
+
+Instead, the SCTP protocol layer builds an skb with the segments correctly
+padded and stored as chained skbs, and skb_segment() splits based on those.
+To signal this, gso_size is set to the special value GSO_BY_FRAGS.
+
+Therefore, any code in the core networking stack must be aware of the
+possibility that gso_size will be GSO_BY_FRAGS and handle that case
+appropriately.
+
+There are some helpers to make this easier:
+
+- skb_is_gso(skb) && skb_is_gso_sctp(skb) is the best way to see if
+ an skb is an SCTP GSO skb.
+
+- For size checks, the skb_gso_validate_*_len family of helpers correctly
+ considers GSO_BY_FRAGS.
+
+- For manipulating packets, skb_increase_gso_size and skb_decrease_gso_size
+ will check for GSO_BY_FRAGS and WARN if asked to manipulate these skbs.
+
+This also affects drivers with the NETIF_F_FRAGLIST & NETIF_F_GSO_SCTP bits
+set. Note also that NETIF_F_GSO_SCTP is included in NETIF_F_GSO_SOFTWARE.

+=======
+
+Overview
+========
+
+phylink is a mechanism to support hot-pluggable networking modules
+without needing to re-initialise the adapter on hot-plug events.
+
+phylink supports conventional phylib-based setups, fixed link setups
+and SFP (Small Formfactor Pluggable) modules at present.
+
+Modes of operation
+==================
+
+phylink has several modes of operation, which depend on the firmware
+settings.
+
+1. PHY mode
+
+ In PHY mode, we use phylib to read the current link settings from
+ the PHY, and pass them to the MAC driver. We expect the MAC driver
+ to configure exactly the modes that are specified without any
+ negotiation being enabled on the link.
+
+2. Fixed mode
+
+ Fixed mode is the same as PHY mode as far as the MAC driver is
+ concerned.
+
+3. In-band mode
+
+ In-band mode is used with 802.3z, SGMII and similar interface modes,
+ and we are expecting to use and honor the in-band negotiation or
+ control word sent across the serdes channel.
+
+By example, what this means is that:
+
+.. code-block:: none
+
+ &eth {
+ phy = <&phy>;
+ phy-mode = "sgmii";
+ };
+
+does not use in-band SGMII signalling. The PHY is expected to follow
+exactly the settings given to it in its :c:func:`mac_config` function.
+The link should be forced up or down appropriately in the
+:c:func:`mac_link_up` and :c:func:`mac_link_down` functions.
+
+.. code-block:: none
+
+ &eth {
+ managed = "in-band-status";
+ phy = <&phy>;
+ phy-mode = "sgmii";
+ };
+
+uses in-band mode, where results from the PHY's negotiation are passed
+to the MAC through the SGMII control word, and the MAC is expected to
+acknowledge the control word. The :c:func:`mac_link_up` and
+:c:func:`mac_link_down` functions must not force the MAC side link
+up and down.
+
+Rough guide to converting a network driver to sfp/phylink
+=========================================================
+
+This guide briefly describes how to convert a network driver from
+phylib to the sfp/phylink support. Please send patches to improve
+this documentation.
+
+1. Optionally split the network driver's phylib update function into
+ three parts dealing with link-down, link-up and reconfiguring the
+ MAC settings. This can be done as a separate preparation commit.
+
+ An example of this preparation can be found in git commit fc548b991fb0.
+
+2. Replace::
+
+ select FIXED_PHY
+ select PHYLIB
+
+ with::
+
+ select PHYLINK
+
+ in the driver's Kconfig stanza.
+
+3. Add::
+
+ #include <linux/phylink.h>
+
+ to the driver's list of header files.
+
+4. Add::
+
+ struct phylink *phylink;
+
+ to the driver's private data structure. We shall refer to the
+ driver's private data pointer as ``priv`` below, and the driver's
+ private data structure as ``struct foo_priv``.
+
+5. Replace the following functions:
+
+ .. flat-table::
+ :header-rows: 1
+ :widths: 1 1
+ :stub-columns: 0
+
+ * - Original function
+ - Replacement function
+ * - phy_start(phydev)
+ - phylink_start(priv->phylink)
+ * - phy_stop(phydev)
+ - phylink_stop(priv->phylink)
+ * - phy_mii_ioctl(phydev, ifr, cmd)
+ - phylink_mii_ioctl(priv->phylink, ifr, cmd)
+ * - phy_ethtool_get_wol(phydev, wol)
+ - phylink_ethtool_get_wol(priv->phylink, wol)
+ * - phy_ethtool_set_wol(phydev, wol)
+ - phylink_ethtool_set_wol(priv->phylink, wol)
+ * - phy_disconnect(phydev)
+ - phylink_disconnect_phy(priv->phylink)
+
+ Please note that some of these functions must be called under the
+ rtnl lock, and will warn if not. This will normally be the case,
+ except if these are called from the driver suspend/resume paths.
+
+6. Add/replace ksettings get/set methods with:
+
+ .. code-block:: c
+
+ static int foo_ethtool_set_link_ksettings(struct net_device *dev,
+ const struct ethtool_link_ksettings *cmd)
+ {
+ struct foo_priv *priv = netdev_priv(dev);
+
+ return phylink_ethtool_ksettings_set(priv->phylink, cmd);
+ }
+
+ static int foo_ethtool_get_link_ksettings(struct net_device *dev,
+ struct ethtool_link_ksettings *cmd)
+ {
+ struct foo_priv *priv = netdev_priv(dev);
+
+ return phylink_ethtool_ksettings_get(priv->phylink, cmd);
+ }
+
+7. Replace the call to:
+
+ phy_dev = of_phy_connect(dev, node, link_func, flags, phy_interface);
+
+ and associated code with a call to:
+
+ err = phylink_of_phy_connect(priv->phylink, node, flags);
+
+ For the most part, ``flags`` can be zero; these flags are passed to
+ the of_phy_attach() inside this function call if a PHY is specified
+ in the DT node ``node``.
+
+ ``node`` should be the DT node which contains the network phy property,
+ fixed link properties, and will also contain the sfp property.
+
+ The setup of fixed links should also be removed; these are handled
+ internally by phylink.
+
+ of_phy_connect() was also passed a function pointer for link updates.
+ This function is replaced by a different form of MAC updates
+ described below in (8).
+
+ Manipulation of the PHY's supported/advertised happens within phylink
+ based on the validate callback, see below in (8).
+
+ Note that the driver no longer needs to store the ``phy_interface``,
+ and also note that ``phy_interface`` becomes a dynamic property,
+ just like the speed, duplex etc. settings.
+
+ Finally, note that the MAC driver has no direct access to the PHY
+ anymore; that is because in the phylink model, the PHY can be
+ dynamic.
+
+8. Add a :c:type:`struct phylink_mac_ops <phylink_mac_ops>` instance to
+ the driver, which is a table of function pointers, and implement
+ these functions. The old link update function for
+ :c:func:`of_phy_connect` becomes three methods: :c:func:`mac_link_up`,
+ :c:func:`mac_link_down`, and :c:func:`mac_config`. If step 1 was
+ performed, then the functionality will have been split there.
+
+ It is important that if in-band negotiation is used,
+ :c:func:`mac_link_up` and :c:func:`mac_link_down` do not prevent the
+ in-band negotiation from completing, since these functions are called
+ when the in-band link state changes - otherwise the link will never
+ come up.
+
+ The :c:func:`validate` method should mask the supplied supported mask,
+ and ``state->advertising`` with the supported ethtool link modes.
+ These are the new ethtool link modes, so bitmask operations must be
+ used. For an example, see drivers/net/ethernet/marvell/mvneta.c.
+
+ The :c:func:`mac_link_state` method is used to read the link state
+ from the MAC, and report back the settings that the MAC is currently
+ using. This is particularly important for in-band negotiation
+ methods such as 1000base-X and SGMII.
+
+ The :c:func:`mac_config` method is used to update the MAC with the
+ requested state, and must avoid unnecessarily taking the link down
+ when making changes to the MAC configuration. This means the
+ function should modify the state and only take the link down when
+ absolutely necessary to change the MAC configuration. An example
+ of how to do this can be found in :c:func:`mvneta_mac_config` in
+ drivers/net/ethernet/marvell/mvneta.c.
+
+ For further information on these methods, please see the inline
+ documentation in :c:type:`struct phylink_mac_ops <phylink_mac_ops>`.
+
+9. Remove calls to of_parse_phandle() for the PHY,
+ of_phy_register_fixed_link() for fixed links etc. from the probe
+ function, and replace with:
+
+ .. code-block:: c
+
+ struct phylink *phylink;
+
+ phylink = phylink_create(dev, node, phy_mode, &phylink_ops);
+ if (IS_ERR(phylink)) {
+ err = PTR_ERR(phylink);
+ fail probe;
+ }
+
+ priv->phylink = phylink;
+
+ and arrange to destroy the phylink in the probe failure path as
+ appropriate and the removal path too by calling:
+
+ .. code-block:: c
+
+ phylink_destroy(priv->phylink);
+
+10. Arrange for MAC link state interrupts to be forwarded into
+ phylink, via:
+
+ .. code-block:: c
+
+ phylink_mac_change(priv->phylink, link_is_up);
+
+ where ``link_is_up`` is true if the link is currently up or false
+ otherwise.
+
+11. Verify that the driver does not call::
+
+ netif_carrier_on()
+ netif_carrier_off()
+
+ as these will interfere with phylink's tracking of the link state,
+ and cause phylink to omit calls via the :c:func:`mac_link_up` and
+ :c:func:`mac_link_down` methods.
+
+Network drivers should call phylink_stop() and phylink_start() via their
+suspend/resume paths, which ensures that the appropriate
+:c:type:`struct phylink_mac_ops <phylink_mac_ops>` methods are called
+as necessary.

+documentation in the kernel source tree

+============
+SNMP counter
+============
+
+This document explains the meaning of SNMP counters.
+
+General IPv4 counters
+=====================
+All layer 4 packets and ICMP packets will change these counters, but
+these counters won't be changed by layer 2 packets (such as STP) or
+ARP packets.
+
+* IpInReceives
+
+Defined in `RFC1213 ipInReceives`_
+
+.. _RFC1213 ipInReceives: https://tools.ietf.org/html/rfc1213#page-26
+
+The number of packets received by the IP layer. It gets increasing at the
+beginning of ip_rcv function, always be updated together with
+IpExtInOctets. It will be increased even if the packet is dropped
+later (e.g. due to the IP header is invalid or the checksum is wrong
+and so on). It indicates the number of aggregated segments after
+GRO/LRO.
+
+* IpInDelivers
+
+Defined in `RFC1213 ipInDelivers`_
+
+.. _RFC1213 ipInDelivers: https://tools.ietf.org/html/rfc1213#page-28
+
+The number of packets delivers to the upper layer protocols. E.g. TCP, UDP,
+ICMP and so on. If no one listens on a raw socket, only kernel
+supported protocols will be delivered, if someone listens on the raw
+socket, all valid IP packets will be delivered.
+
+* IpOutRequests
+
+Defined in `RFC1213 ipOutRequests`_
+
+.. _RFC1213 ipOutRequests: https://tools.ietf.org/html/rfc1213#page-28
+
+The number of packets sent via IP layer, for both single cast and
+multicast packets, and would always be updated together with
+IpExtOutOctets.
+
+* IpExtInOctets and IpExtOutOctets
+
+They are Linux kernel extensions, no RFC definitions. Please note,
+RFC1213 indeed defines ifInOctets and ifOutOctets, but they
+are different things. The ifInOctets and ifOutOctets include the MAC
+layer header size but IpExtInOctets and IpExtOutOctets don't, they
+only include the IP layer header and the IP layer data.
+
+* IpExtInNoECTPkts, IpExtInECT1Pkts, IpExtInECT0Pkts, IpExtInCEPkts
+
+They indicate the number of four kinds of ECN IP packets, please refer
+`Explicit Congestion Notification`_ for more details.
+
+.. _Explicit Congestion Notification: https://tools.ietf.org/html/rfc3168#page-6
+
+These 4 counters calculate how many packets received per ECN
+status. They count the real frame number regardless the LRO/GRO. So
+for the same packet, you might find that IpInReceives count 1, but
+IpExtInNoECTPkts counts 2 or more.
+
+* IpInHdrErrors
+
+Defined in `RFC1213 ipInHdrErrors`_. It indicates the packet is
+dropped due to the IP header error. It might happen in both IP input
+and IP forward paths.
+
+.. _RFC1213 ipInHdrErrors: https://tools.ietf.org/html/rfc1213#page-27
+
+* IpInAddrErrors
+
+Defined in `RFC1213 ipInAddrErrors`_. It will be increased in two
+scenarios: (1) The IP address is invalid. (2) The destination IP
+address is not a local address and IP forwarding is not enabled
+
+.. _RFC1213 ipInAddrErrors: https://tools.ietf.org/html/rfc1213#page-27
+
+* IpExtInNoRoutes
+
+This counter means the packet is dropped when the IP stack receives a
+packet and can't find a route for it from the route table. It might
+happen when IP forwarding is enabled and the destination IP address is
+not a local address and there is no route for the destination IP
+address.
+
+* IpInUnknownProtos
+
+Defined in `RFC1213 ipInUnknownProtos`_. It will be increased if the
+layer 4 protocol is unsupported by kernel. If an application is using
+raw socket, kernel will always deliver the packet to the raw socket
+and this counter won't be increased.
+
+.. _RFC1213 ipInUnknownProtos: https://tools.ietf.org/html/rfc1213#page-27
+
+* IpExtInTruncatedPkts
+
+For IPv4 packet, it means the actual data size is smaller than the
+"Total Length" field in the IPv4 header.
+
+* IpInDiscards
+
+Defined in `RFC1213 ipInDiscards`_. It indicates the packet is dropped
+in the IP receiving path and due to kernel internal reasons (e.g. no
+enough memory).
+
+.. _RFC1213 ipInDiscards: https://tools.ietf.org/html/rfc1213#page-28
+
+* IpOutDiscards
+
+Defined in `RFC1213 ipOutDiscards`_. It indicates the packet is
+dropped in the IP sending path and due to kernel internal reasons.
+
+.. _RFC1213 ipOutDiscards: https://tools.ietf.org/html/rfc1213#page-28
+
+* IpOutNoRoutes
+
+Defined in `RFC1213 ipOutNoRoutes`_. It indicates the packet is
+dropped in the IP sending path and no route is found for it.
+
+.. _RFC1213 ipOutNoRoutes: https://tools.ietf.org/html/rfc1213#page-29
+
+ICMP counters
+=============
+* IcmpInMsgs and IcmpOutMsgs
+
+Defined by `RFC1213 icmpInMsgs`_ and `RFC1213 icmpOutMsgs`_
+
+.. _RFC1213 icmpInMsgs: https://tools.ietf.org/html/rfc1213#page-41
+.. _RFC1213 icmpOutMsgs: https://tools.ietf.org/html/rfc1213#page-43
+
+As mentioned in the RFC1213, these two counters include errors, they
+would be increased even if the ICMP packet has an invalid type. The
+ICMP output path will check the header of a raw socket, so the
+IcmpOutMsgs would still be updated if the IP header is constructed by
+a userspace program.
+
+* ICMP named types
+
+| These counters include most of common ICMP types, they are:
+| IcmpInDestUnreachs: `RFC1213 icmpInDestUnreachs`_
+| IcmpInTimeExcds: `RFC1213 icmpInTimeExcds`_
+| IcmpInParmProbs: `RFC1213 icmpInParmProbs`_

+.. _RFC1213 icmpInAddrMaskReps: https://tools.ietf.org/html/rfc1213#page-43
+
+.. _RFC1213 icmpOutDestUnreachs: https://tools.ietf.org/html/rfc1213#page-44
+.. _RFC1213 icmpOutTimeExcds: https://tools.ietf.org/html/rfc1213#page-44
+.. _RFC1213 icmpOutParmProbs: https://tools.ietf.org/html/rfc1213#page-44
+.. _RFC1213 icmpOutSrcQuenchs: https://tools.ietf.org/html/rfc1213#page-44
+.. _RFC1213 icmpOutRedirects: https://tools.ietf.org/html/rfc1213#page-44

+.. _RFC1213 icmpOutAddrMasks: https://tools.ietf.org/html/rfc1213#page-45
+.. _RFC1213 icmpOutAddrMaskReps: https://tools.ietf.org/html/rfc1213#page-46
+
+Every ICMP type has two counters: 'In' and 'Out'. E.g., for the ICMP
+Echo packet, they are IcmpInEchos and IcmpOutEchos. Their meanings are
+straightforward. The 'In' counter means kernel receives such a packet
+and the 'Out' counter means kernel sends such a packet.
+
+* ICMP numeric types
+
+They are IcmpMsgInType[N] and IcmpMsgOutType[N], the [N] indicates the
+ICMP type number. These counters track all kinds of ICMP packets. The
+ICMP type number definition could be found in the `ICMP parameters`_
+document.
+
+.. _ICMP parameters: https://www.iana.org/assignments/icmp-parameters/icmp-parameters.xhtml
+
+For example, if the Linux kernel sends an ICMP Echo packet, the
+IcmpMsgOutType8 would increase 1. And if kernel gets an ICMP Echo Reply
+packet, IcmpMsgInType0 would increase 1.
+
+* IcmpInCsumErrors
+
+This counter indicates the checksum of the ICMP packet is
+wrong. Kernel verifies the checksum after updating the IcmpInMsgs and
+before updating IcmpMsgInType[N]. If a packet has bad checksum, the
+IcmpInMsgs would be updated but none of IcmpMsgInType[N] would be updated.
+
+* IcmpInErrors and IcmpOutErrors
+
+Defined by `RFC1213 icmpInErrors`_ and `RFC1213 icmpOutErrors`_
+
+.. _RFC1213 icmpInErrors: https://tools.ietf.org/html/rfc1213#page-41
+.. _RFC1213 icmpOutErrors: https://tools.ietf.org/html/rfc1213#page-43
+
+When an error occurs in the ICMP packet handler path, these two
+counters would be updated. The receiving packet path use IcmpInErrors
+and the sending packet path use IcmpOutErrors. When IcmpInCsumErrors
+is increased, IcmpInErrors would always be increased too.
+
+relationship of the ICMP counters
+---------------------------------
+The sum of IcmpMsgOutType[N] is always equal to IcmpOutMsgs, as they
+are updated at the same time. The sum of IcmpMsgInType[N] plus
+IcmpInErrors should be equal or larger than IcmpInMsgs. When kernel
+receives an ICMP packet, kernel follows below logic:
+
+1. increase IcmpInMsgs
+2. if has any error, update IcmpInErrors and finish the process
+3. update IcmpMsgOutType[N]
+4. handle the packet depending on the type, if has any error, update
+ IcmpInErrors and finish the process
+
+So if all errors occur in step (2), IcmpInMsgs should be equal to the
+sum of IcmpMsgOutType[N] plus IcmpInErrors. If all errors occur in
+step (4), IcmpInMsgs should be equal to the sum of
+IcmpMsgOutType[N]. If the errors occur in both step (2) and step (4),
+IcmpInMsgs should be less than the sum of IcmpMsgOutType[N] plus
+IcmpInErrors.
+
+General TCP counters
+====================
+* TcpInSegs
+
+Defined in `RFC1213 tcpInSegs`_
+
+.. _RFC1213 tcpInSegs: https://tools.ietf.org/html/rfc1213#page-48
+
+The number of packets received by the TCP layer. As mentioned in
+RFC1213, it includes the packets received in error, such as checksum
+error, invalid TCP header and so on. Only one error won't be included:
+if the layer 2 destination address is not the NIC's layer 2
+address. It might happen if the packet is a multicast or broadcast
+packet, or the NIC is in promiscuous mode. In these situations, the
+packets would be delivered to the TCP layer, but the TCP layer will discard
+these packets before increasing TcpInSegs. The TcpInSegs counter
+isn't aware of GRO. So if two packets are merged by GRO, the TcpInSegs
+counter would only increase 1.
+
+* TcpOutSegs
+
+Defined in `RFC1213 tcpOutSegs`_
+
+.. _RFC1213 tcpOutSegs: https://tools.ietf.org/html/rfc1213#page-48
+
+The number of packets sent by the TCP layer. As mentioned in RFC1213,
+it excludes the retransmitted packets. But it includes the SYN, ACK
+and RST packets. Doesn't like TcpInSegs, the TcpOutSegs is aware of
+GSO, so if a packet would be split to 2 by GSO, TcpOutSegs will
+increase 2.
+
+* TcpActiveOpens
+
+Defined in `RFC1213 tcpActiveOpens`_
+
+.. _RFC1213 tcpActiveOpens: https://tools.ietf.org/html/rfc1213#page-47
+
+It means the TCP layer sends a SYN, and come into the SYN-SENT
+state. Every time TcpActiveOpens increases 1, TcpOutSegs should always
+increase 1.
+
+* TcpPassiveOpens
+
+Defined in `RFC1213 tcpPassiveOpens`_
+
+.. _RFC1213 tcpPassiveOpens: https://tools.ietf.org/html/rfc1213#page-47
+
+It means the TCP layer receives a SYN, replies a SYN+ACK, come into
+the SYN-RCVD state.
+
+* TcpExtTCPRcvCoalesce
+
+When packets are received by the TCP layer and are not be read by the
+application, the TCP layer will try to merge them. This counter
+indicate how many packets are merged in such situation. If GRO is
+enabled, lots of packets would be merged by GRO, these packets
+wouldn't be counted to TcpExtTCPRcvCoalesce.
+
+* TcpExtTCPAutoCorking
+
+When sending packets, the TCP layer will try to merge small packets to
+a bigger one. This counter increase 1 for every packet merged in such
+situation. Please refer to the LWN article for more details:
+https://lwn.net/Articles/576263/
+
+* TcpExtTCPOrigDataSent
+
+This counter is explained by `kernel commit f19c29e3e391`_, I pasted the
+explaination below::
+
+ TCPOrigDataSent: number of outgoing packets with original data (excluding
+ retransmission but including data-in-SYN). This counter is different from
+ TcpOutSegs because TcpOutSegs also tracks pure ACKs. TCPOrigDataSent is
+ more useful to track the TCP retransmission rate.
+
+* TCPSynRetrans
+
+This counter is explained by `kernel commit f19c29e3e391`_, I pasted the
+explaination below::
+
+ TCPSynRetrans: number of SYN and SYN/ACK retransmits to break down
+ retransmissions into SYN, fast-retransmits, timeout retransmits, etc.
+
+* TCPFastOpenActiveFail
+
+This counter is explained by `kernel commit f19c29e3e391`_, I pasted the
+explaination below::
+
+ TCPFastOpenActiveFail: Fast Open attempts (SYN/data) failed because
+ the remote does not accept it or the attempts timed out.
+
+.. _kernel commit f19c29e3e391: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f19c29e3e391a66a273e9afebaf01917245148cd
+
+* TcpExtListenOverflows and TcpExtListenDrops
+
+When kernel receives a SYN from a client, and if the TCP accept queue
+is full, kernel will drop the SYN and add 1 to TcpExtListenOverflows.
+At the same time kernel will also add 1 to TcpExtListenDrops. When a
+TCP socket is in LISTEN state, and kernel need to drop a packet,
+kernel would always add 1 to TcpExtListenDrops. So increase
+TcpExtListenOverflows would let TcpExtListenDrops increasing at the
+same time, but TcpExtListenDrops would also increase without
+TcpExtListenOverflows increasing, e.g. a memory allocation fail would
+also let TcpExtListenDrops increase.
+
+Note: The above explanation is based on kernel 4.10 or above version, on
+an old kernel, the TCP stack has different behavior when TCP accept
+queue is full. On the old kernel, TCP stack won't drop the SYN, it
+would complete the 3-way handshake. As the accept queue is full, TCP
+stack will keep the socket in the TCP half-open queue. As it is in the
+half open queue, TCP stack will send SYN+ACK on an exponential backoff
+timer, after client replies ACK, TCP stack checks whether the accept
+queue is still full, if it is not full, moves the socket to the accept
+queue, if it is full, keeps the socket in the half-open queue, at next
+time client replies ACK, this socket will get another chance to move
+to the accept queue.
+
+
+TCP Fast Open
+=============
+* TcpEstabResets
+
+Defined in `RFC1213 tcpEstabResets`_.

+
+When the TCP stack wants to retransmit a packet, and finds that packet

+
+TCP Fast Path
+=============
+When kernel receives a TCP packet, it has two paths to handler the
+packet, one is fast path, another is slow path. The comment in kernel
+code provides a good explanation of them, I pasted them below::
+
+ It is split into a fast path and a slow path. The fast path is
+ disabled when:
+
+ - A zero window was announced from us
+ - zero window probing
+ is only handled properly on the slow path.
+ - Out of order segments arrived.
+ - Urgent data is expected.
+ - There is no buffer space left
+ - Unexpected TCP flags/window values/header lengths are received
+ (detected by checking the TCP header against pred_flags)
+ - Data is sent in both directions. The fast path only supports pure senders
+ or pure receivers (this means either the sequence number or the ack
+ value must stay constant)
+ - Unexpected TCP option.
+
+Kernel will try to use fast path unless any of the above conditions
+are satisfied. If the packets are out of order, kernel will handle
+them in slow path, which means the performance might be not very
+good. Kernel would also come into slow path if the "Delayed ack" is
+used, because when using "Delayed ack", the data is sent in both
+directions. When the TCP window scale option is not used, kernel will
+try to enable fast path immediately when the connection comes into the
+established state, but if the TCP window scale option is used, kernel
+will disable the fast path at first, and try to enable it after kernel
+receives packets.
+
+* TcpExtTCPPureAcks and TcpExtTCPHPAcks
+
+If a packet set ACK flag and has no data, it is a pure ACK packet, if
+kernel handles it in the fast path, TcpExtTCPHPAcks will increase 1,
+if kernel handles it in the slow path, TcpExtTCPPureAcks will
+increase 1.
+
+* TcpExtTCPHPHits
+
+If a TCP packet has data (which means it is not a pure ACK packet),
+and this packet is handled in the fast path, TcpExtTCPHPHits will
+increase 1.
+
+
+TCP abort
+=========
+* TcpExtTCPAbortOnData
+
+It means TCP layer has data in flight, but need to close the
+connection. So TCP layer sends a RST to the other side, indicate the
+connection is not closed very graceful. An easy way to increase this
+counter is using the SO_LINGER option. Please refer to the SO_LINGER
+section of the `socket man page`_:
+
+.. _socket man page: http://man7.org/linux/man-pages/man7/socket.7.html
+
+By default, when an application closes a connection, the close function
+will return immediately and kernel will try to send the in-flight data
+async. If you use the SO_LINGER option, set l_onoff to 1, and l_linger
+to a positive number, the close function won't return immediately, but
+wait for the in-flight data are acked by the other side, the max wait
+time is l_linger seconds. If set l_onoff to 1 and set l_linger to 0,
+when the application closes a connection, kernel will send a RST
+immediately and increase the TcpExtTCPAbortOnData counter.
+
+* TcpExtTCPAbortOnClose
+
+This counter means the application has unread data in the TCP layer when
+the application wants to close the TCP connection. In such a situation,
+kernel will send a RST to the other side of the TCP connection.
+
+* TcpExtTCPAbortOnMemory
+
+When an application closes a TCP connection, kernel still need to track
+the connection, let it complete the TCP disconnect process. E.g. an
+app calls the close method of a socket, kernel sends fin to the other
+side of the connection, then the app has no relationship with the
+socket any more, but kernel need to keep the socket, this socket
+becomes an orphan socket, kernel waits for the reply of the other side,
+and would come to the TIME_WAIT state finally. When kernel has no
+enough memory to keep the orphan socket, kernel would send an RST to
+the other side, and delete the socket, in such situation, kernel will
+increase 1 to the TcpExtTCPAbortOnMemory. Two conditions would trigger
+TcpExtTCPAbortOnMemory:
+
+1. the memory used by the TCP protocol is higher than the third value of
+the tcp_mem. Please refer the tcp_mem section in the `TCP man page`_:
+
+.. _TCP man page: http://man7.org/linux/man-pages/man7/tcp.7.html
+
+2. the orphan socket count is higher than net.ipv4.tcp_max_orphans
+
+
+* TcpExtTCPAbortOnTimeout
+
+This counter will increase when any of the TCP timers expire. In such
+situation, kernel won't send RST, just give up the connection.
+
+* TcpExtTCPAbortOnLinger
+
+When a TCP connection comes into FIN_WAIT_2 state, instead of waiting
+for the fin packet from the other side, kernel could send a RST and
+delete the socket immediately. This is not the default behavior of
+Linux kernel TCP stack. By configuring the TCP_LINGER2 socket option,
+you could let kernel follow this behavior.
+
+* TcpExtTCPAbortFailed
+
+The kernel TCP layer will send RST if the `RFC2525 2.17 section`_ is
+satisfied. If an internal error occurs during this process,
+TcpExtTCPAbortFailed will be increased.
+
+.. _RFC2525 2.17 section: https://tools.ietf.org/html/rfc2525#page-50
+
+TCP Hybrid Slow Start
+=====================
+The Hybrid Slow Start algorithm is an enhancement of the traditional
+TCP congestion window Slow Start algorithm. It uses two pieces of
+information to detect whether the max bandwidth of the TCP path is
+approached. The two pieces of information are ACK train length and
+increase in packet delay. For detail information, please refer the
+`Hybrid Slow Start paper`_. Either ACK train length or packet delay
+hits a specific threshold, the congestion control algorithm will come
+into the Congestion Avoidance state. Until v4.20, two congestion
+control algorithms are using Hybrid Slow Start, they are cubic (the
+default congestion control algorithm) and cdg. Four snmp counters
+relate with the Hybrid Slow Start algorithm.
+
+.. _Hybrid Slow Start paper: https://pdfs.semanticscholar.org/25e9/ef3f03315782c7f1cbcd31b587857adae7d1.pdf
+
+* TcpExtTCPHystartTrainDetect
+
+How many times the ACK train length threshold is detected
+
+* TcpExtTCPHystartTrainCwnd
+
+The sum of CWND detected by ACK train length. Dividing this value by
+TcpExtTCPHystartTrainDetect is the average CWND which detected by the
+ACK train length.
+
+* TcpExtTCPHystartDelayDetect
+
+How many times the packet delay threshold is detected.
+
+* TcpExtTCPHystartDelayCwnd
+
+The sum of CWND detected by packet delay. Dividing this value by
+TcpExtTCPHystartDelayDetect is the average CWND which detected by the
+packet delay.
+
+TCP retransmission and congestion control
+=========================================
+The TCP protocol has two retransmission mechanisms: SACK and fast
+recovery. They are exclusive with each other. When SACK is enabled,
+the kernel TCP stack would use SACK, or kernel would use fast
+recovery. The SACK is a TCP option, which is defined in `RFC2018`_,
+the fast recovery is defined in `RFC6582`_, which is also called
+'Reno'.
+
+The TCP congestion control is a big and complex topic. To understand
+the related snmp counter, we need to know the states of the congestion
+control state machine. There are 5 states: Open, Disorder, CWR,
+Recovery and Loss. For details about these states, please refer page 5
+and page 6 of this document:
+https://pdfs.semanticscholar.org/0e9c/968d09ab2e53e24c4dca5b2d67c7f7140f8e.pdf
+
+.. _RFC2018: https://tools.ietf.org/html/rfc2018
+.. _RFC6582: https://tools.ietf.org/html/rfc6582
+
+* TcpExtTCPRenoRecovery and TcpExtTCPSackRecovery
+
+When the congestion control comes into Recovery state, if sack is
+used, TcpExtTCPSackRecovery increases 1, if sack is not used,
+TcpExtTCPRenoRecovery increases 1. These two counters mean the TCP
+stack begins to retransmit the lost packets.
+
+* TcpExtTCPSACKReneging
+
+A packet was acknowledged by SACK, but the receiver has dropped this
+packet, so the sender needs to retransmit this packet. In this
+situation, the sender adds 1 to TcpExtTCPSACKReneging. A receiver
+could drop a packet which has been acknowledged by SACK, although it is
+unusual, it is allowed by the TCP protocol. The sender doesn't really
+know what happened on the receiver side. The sender just waits until
+the RTO expires for this packet, then the sender assumes this packet
+has been dropped by the receiver.
+
+* TcpExtTCPRenoReorder
+
+The reorder packet is detected by fast recovery. It would only be used
+if SACK is disabled. The fast recovery algorithm detects recorder by
+the duplicate ACK number. E.g., if retransmission is triggered, and
+the original retransmitted packet is not lost, it is just out of
+order, the receiver would acknowledge multiple times, one for the
+retransmitted packet, another for the arriving of the original out of
+order packet. Thus the sender would find more ACks than its
+expectation, and the sender knows out of order occurs.
+
+* TcpExtTCPTSReorder
+
+The reorder packet is detected when a hole is filled. E.g., assume the
+sender sends packet 1,2,3,4,5, and the receiving order is
+1,2,4,5,3. When the sender receives the ACK of packet 3 (which will
+fill the hole), two conditions will let TcpExtTCPTSReorder increase
+1: (1) if the packet 3 is not re-retransmitted yet. (2) if the packet
+3 is retransmitted but the timestamp of the packet 3's ACK is earlier
+than the retransmission timestamp.
+
+* TcpExtTCPSACKReorder
+
+The reorder packet detected by SACK. The SACK has two methods to
+detect reorder: (1) DSACK is received by the sender. It means the
+sender sends the same packet more than one times. And the only reason
+is the sender believes an out of order packet is lost so it sends the
+packet again. (2) Assume packet 1,2,3,4,5 are sent by the sender, and
+the sender has received SACKs for packet 2 and 5, now the sender
+receives SACK for packet 4 and the sender doesn't retransmit the
+packet yet, the sender would know packet 4 is out of order. The TCP
+stack of kernel will increase TcpExtTCPSACKReorder for both of the
+above scenarios.
+
+* TcpExtTCPSlowStartRetrans
+
+The TCP stack wants to retransmit a packet and the congestion control
+state is 'Loss'.
+
+* TcpExtTCPFastRetrans
+
+The TCP stack wants to retransmit a packet and the congestion control
+state is not 'Loss'.
+
+* TcpExtTCPLostRetransmit
+
+A SACK points out that a retransmission packet is lost again.
+
+* TcpExtTCPRetransFail
+
+The TCP stack tries to deliver a retransmission packet to lower layers
+but the lower layers return an error.
+
+* TcpExtTCPSynRetrans
+
+The TCP stack retransmits a SYN packet.
+
+DSACK
+=====
+The DSACK is defined in `RFC2883`_. The receiver uses DSACK to report
+duplicate packets to the sender. There are two kinds of
+duplications: (1) a packet which has been acknowledged is
+duplicate. (2) an out of order packet is duplicate. The TCP stack
+counts these two kinds of duplications on both receiver side and
+sender side.
+
+.. _RFC2883 : https://tools.ietf.org/html/rfc2883
+
+* TcpExtTCPDSACKOldSent
+
+The TCP stack receives a duplicate packet which has been acked, so it
+sends a DSACK to the sender.
+
+* TcpExtTCPDSACKOfoSent
+
+The TCP stack receives an out of order duplicate packet, so it sends a
+DSACK to the sender.
+
+* TcpExtTCPDSACKRecv
+
+The TCP stack receives a DSACK, which indicates an acknowledged
+duplicate packet is received.
+
+* TcpExtTCPDSACKOfoRecv
+
+The TCP stack receives a DSACK, which indicate an out of order
+duplicate packet is received.
+
+invalid SACK and DSACK
+======================
+When a SACK (or DSACK) block is invalid, a corresponding counter would
+be updated. The validation method is base on the start/end sequence
+number of the SACK block. For more details, please refer the comment
+of the function tcp_is_sackblock_valid in the kernel source code. A
+SACK option could have up to 4 blocks, they are checked
+individually. E.g., if 3 blocks of a SACk is invalid, the
+corresponding counter would be updated 3 times. The comment of the
+`Add counters for discarded SACK blocks`_ patch has additional
+explaination:
+
+.. _Add counters for discarded SACK blocks: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=18f02545a9a16c9a89778b91a162ad16d510bb32
+
+* TcpExtTCPSACKDiscard
+
+This counter indicates how many SACK blocks are invalid. If the invalid
+SACK block is caused by ACK recording, the TCP stack will only ignore
+it and won't update this counter.
+
+* TcpExtTCPDSACKIgnoredOld and TcpExtTCPDSACKIgnoredNoUndo
+
+When a DSACK block is invalid, one of these two counters would be
+updated. Which counter will be updated depends on the undo_marker flag
+of the TCP socket. If the undo_marker is not set, the TCP stack isn't
+likely to re-transmit any packets, and we still receive an invalid
+DSACK block, the reason might be that the packet is duplicated in the
+middle of the network. In such scenario, TcpExtTCPDSACKIgnoredNoUndo
+will be updated. If the undo_marker is set, TcpExtTCPDSACKIgnoredOld
+will be updated. As implied in its name, it might be an old packet.
+
+SACK shift
+==========
+The linux networking stack stores data in sk_buff struct (skb for
+short). If a SACK block acrosses multiple skb, the TCP stack will try
+to re-arrange data in these skb. E.g. if a SACK block acknowledges seq
+10 to 15, skb1 has seq 10 to 13, skb2 has seq 14 to 20. The seq 14 and
+15 in skb2 would be moved to skb1. This operation is 'shift'. If a
+SACK block acknowledges seq 10 to 20, skb1 has seq 10 to 13, skb2 has
+seq 14 to 20. All data in skb2 will be moved to skb1, and skb2 will be
+discard, this operation is 'merge'.
+
+* TcpExtTCPSackShifted
+
+A skb is shifted
+
+* TcpExtTCPSackMerged
+
+A skb is merged
+
+* TcpExtTCPSackShiftFallback
+
+A skb should be shifted or merged, but the TCP stack doesn't do it for
+some reasons.
+
+TCP out of order
+================
+* TcpExtTCPOFOQueue
+
+The TCP layer receives an out of order packet and has enough memory
+to queue it.
+
+* TcpExtTCPOFODrop
+
+The TCP layer receives an out of order packet but doesn't have enough
+memory, so drops it. Such packets won't be counted into
+TcpExtTCPOFOQueue.
+
+* TcpExtTCPOFOMerge
+
+The received out of order packet has an overlay with the previous
+packet. the overlay part will be dropped. All of TcpExtTCPOFOMerge
+packets will also be counted into TcpExtTCPOFOQueue.
+
+TCP PAWS
+========
+PAWS (Protection Against Wrapped Sequence numbers) is an algorithm
+which is used to drop old packets. It depends on the TCP
+timestamps. For detail information, please refer the `timestamp wiki`_
+and the `RFC of PAWS`_.
+
+.. _RFC of PAWS: https://tools.ietf.org/html/rfc1323#page-17
+.. _timestamp wiki: https://en.wikipedia.org/wiki/Transmission_Control_Protocol#TCP_timestamps
+
+* TcpExtPAWSActive
+
+Packets are dropped by PAWS in Syn-Sent status.
+
+* TcpExtPAWSEstab
+
+Packets are dropped by PAWS in any status other than Syn-Sent.
+
+TCP ACK skip
+============
+In some scenarios, kernel would avoid sending duplicate ACKs too
+frequently. Please find more details in the tcp_invalid_ratelimit
+section of the `sysctl document`_. When kernel decides to skip an ACK
+due to tcp_invalid_ratelimit, kernel would update one of below
+counters to indicate the ACK is skipped in which scenario. The ACK
+would only be skipped if the received packet is either a SYN packet or
+it has no data.
+
+.. _sysctl document: https://www.kernel.org/doc/Documentation/networking/ip-sysctl.txt
+
+* TcpExtTCPACKSkippedSynRecv
+
+The ACK is skipped in Syn-Recv status. The Syn-Recv status means the
+TCP stack receives a SYN and replies SYN+ACK. Now the TCP stack is
+waiting for an ACK. Generally, the TCP stack doesn't need to send ACK
+in the Syn-Recv status. But in several scenarios, the TCP stack need
+to send an ACK. E.g., the TCP stack receives the same SYN packet
+repeately, the received packet does not pass the PAWS check, or the
+received packet sequence number is out of window. In these scenarios,
+the TCP stack needs to send ACK. If the ACk sending frequency is higher than
+tcp_invalid_ratelimit allows, the TCP stack will skip sending ACK and
+increase TcpExtTCPACKSkippedSynRecv.
+
+
+* TcpExtTCPACKSkippedPAWS
+
+The ACK is skipped due to PAWS (Protect Against Wrapped Sequence
+numbers) check fails. If the PAWS check fails in Syn-Recv, Fin-Wait-2
+or Time-Wait statuses, the skipped ACK would be counted to
+TcpExtTCPACKSkippedSynRecv, TcpExtTCPACKSkippedFinWait2 or
+TcpExtTCPACKSkippedTimeWait. In all other statuses, the skipped ACK
+would be counted to TcpExtTCPACKSkippedPAWS.
+
+* TcpExtTCPACKSkippedSeq
+
+The sequence number is out of window and the timestamp passes the PAWS
+check and the TCP status is not Syn-Recv, Fin-Wait-2, and Time-Wait.
+
+* TcpExtTCPACKSkippedFinWait2
+
+The ACK is skipped in Fin-Wait-2 status, the reason would be either
+PAWS check fails or the received sequence number is out of window.
+
+* TcpExtTCPACKSkippedTimeWait
+
+Tha ACK is skipped in Time-Wait status, the reason would be either
+PAWS check failed or the received sequence number is out of window.
+
+* TcpExtTCPACKSkippedChallenge
+
+The ACK is skipped if the ACK is a challenge ACK. The RFC 5961 defines
+3 kind of challenge ACK, please refer `RFC 5961 section 3.2`_,
+`RFC 5961 section 4.2`_ and `RFC 5961 section 5.2`_. Besides these
+three scenarios, In some TCP status, the linux TCP stack would also
+send challenge ACKs if the ACK number is before the first
+unacknowledged number (more strict than `RFC 5961 section 5.2`_).
+
+.. _RFC 5961 section 3.2: https://tools.ietf.org/html/rfc5961#page-7
+.. _RFC 5961 section 4.2: https://tools.ietf.org/html/rfc5961#page-9
+.. _RFC 5961 section 5.2: https://tools.ietf.org/html/rfc5961#page-11
+
+TCP receive window
+==================
+* TcpExtTCPWantZeroWindowAdv
+
+Depending on current memory usage, the TCP stack tries to set receive
+window to zero. But the receive window might still be a no-zero
+value. For example, if the previous window size is 10, and the TCP
+stack receives 3 bytes, the current window size would be 7 even if the
+window size calculated by the memory usage is zero.
+
+* TcpExtTCPToZeroWindowAdv
+
+The TCP receive window is set to zero from a no-zero value.
+
+* TcpExtTCPFromZeroWindowAdv
+
+The TCP receive window is set to no-zero value from zero.
+
+
+Delayed ACK
+===========
+The TCP Delayed ACK is a technique which is used for reducing the
+packet count in the network. For more details, please refer the
+`Delayed ACK wiki`_
+
+.. _Delayed ACK wiki: https://en.wikipedia.org/wiki/TCP_delayed_acknowledgment
+
+* TcpExtDelayedACKs
+
+A delayed ACK timer expires. The TCP stack will send a pure ACK packet
+and exit the delayed ACK mode.
+
+* TcpExtDelayedACKLocked
+
+A delayed ACK timer expires, but the TCP stack can't send an ACK
+immediately due to the socket is locked by a userspace program. The
+TCP stack will send a pure ACK later (after the userspace program
+unlock the socket). When the TCP stack sends the pure ACK later, the
+TCP stack will also update TcpExtDelayedACKs and exit the delayed ACK
+mode.
+
+* TcpExtDelayedACKLost
+
+It will be updated when the TCP stack receives a packet which has been
+ACKed. A Delayed ACK loss might cause this issue, but it would also be
+triggered by other reasons, such as a packet is duplicated in the
+network.
+
+Tail Loss Probe (TLP)
+=====================
+TLP is an algorithm which is used to detect TCP packet loss. For more
+details, please refer the `TLP paper`_.
+
+.. _TLP paper: https://tools.ietf.org/html/draft-dukkipati-tcpm-tcp-loss-probe-01
+
+* TcpExtTCPLossProbes
+
+A TLP probe packet is sent.
+
+* TcpExtTCPLossProbeRecovery
+
+A packet loss is detected and recovered by TLP.
+
+TCP Fast Open
+=============
+TCP Fast Open is a technology which allows data transfer before the
+3-way handshake complete. Please refer the `TCP Fast Open wiki`_ for a
+general description.
+
+.. _TCP Fast Open wiki: https://en.wikipedia.org/wiki/TCP_Fast_Open
+
+* TcpExtTCPFastOpenActive
+
+When the TCP stack receives an ACK packet in the SYN-SENT status, and
+the ACK packet acknowledges the data in the SYN packet, the TCP stack
+understand the TFO cookie is accepted by the other side, then it
+updates this counter.
+
+* TcpExtTCPFastOpenActiveFail
+
+This counter indicates that the TCP stack initiated a TCP Fast Open,
+but it failed. This counter would be updated in three scenarios: (1)
+the other side doesn't acknowledge the data in the SYN packet. (2) The
+SYN packet which has the TFO cookie is timeout at least once. (3)
+after the 3-way handshake, the retransmission timeout happens
+net.ipv4.tcp_retries1 times, because some middle-boxes may black-hole
+fast open after the handshake.
+
+* TcpExtTCPFastOpenPassive
+
+This counter indicates how many times the TCP stack accepts the fast
+open request.
+
+* TcpExtTCPFastOpenPassiveFail
+
+This counter indicates how many times the TCP stack rejects the fast
+open request. It is caused by either the TFO cookie is invalid or the
+TCP stack finds an error during the socket creating process.
+
+* TcpExtTCPFastOpenListenOverflow
+
+When the pending fast open request number is larger than
+fastopenq->max_qlen, the TCP stack will reject the fast open request
+and update this counter. When this counter is updated, the TCP stack
+won't update TcpExtTCPFastOpenPassive or
+TcpExtTCPFastOpenPassiveFail. The fastopenq->max_qlen is set by the
+TCP_FASTOPEN socket operation and it could not be larger than
+net.core.somaxconn. For example:
+
+setsockopt(sfd, SOL_TCP, TCP_FASTOPEN, &qlen, sizeof(qlen));
+
+* TcpExtTCPFastOpenCookieReqd
+
+This counter indicates how many times a client wants to request a TFO
+cookie.
+
+SYN cookies
+===========
+SYN cookies are used to mitigate SYN flood, for details, please refer
+the `SYN cookies wiki`_.
+
+.. _SYN cookies wiki: https://en.wikipedia.org/wiki/SYN_cookies
+
+* TcpExtSyncookiesSent
+
+It indicates how many SYN cookies are sent.
+
+* TcpExtSyncookiesRecv
+
+How many reply packets of the SYN cookies the TCP stack receives.
+
+* TcpExtSyncookiesFailed
+
+The MSS decoded from the SYN cookie is invalid. When this counter is
+updated, the received packet won't be treated as a SYN cookie and the
+TcpExtSyncookiesRecv counter wont be updated.
+
+Challenge ACK
+=============
+For details of challenge ACK, please refer the explaination of
+TcpExtTCPACKSkippedChallenge.
+
+* TcpExtTCPChallengeACK
+
+The number of challenge acks sent.
+
+* TcpExtTCPSYNChallenge
+
+The number of challenge acks sent in response to SYN packets. After
+updates this counter, the TCP stack might send a challenge ACK and
+update the TcpExtTCPChallengeACK counter, or it might also skip to
+send the challenge and update the TcpExtTCPACKSkippedChallenge.
+
+prune
+=====
+When a socket is under memory pressure, the TCP stack will try to
+reclaim memory from the receiving queue and out of order queue. One of
+the reclaiming method is 'collapse', which means allocate a big sbk,
+copy the contiguous skbs to the single big skb, and free these
+contiguous skbs.
+
+* TcpExtPruneCalled
+
+The TCP stack tries to reclaim memory for a socket. After updates this
+counter, the TCP stack will try to collapse the out of order queue and
+the receiving queue. If the memory is still not enough, the TCP stack
+will try to discard packets from the out of order queue (and update the
+TcpExtOfoPruned counter)
+
+* TcpExtOfoPruned
+
+The TCP stack tries to discard packet on the out of order queue.
+
+* TcpExtRcvPruned
+
+After 'collapse' and discard packets from the out of order queue, if
+the actually used memory is still larger than the max allowed memory,
+this counter will be updated. It means the 'prune' fails.
+
+* TcpExtTCPRcvCollapsed
+
+This counter indicates how many skbs are freed during 'collapse'.

+The nstayt result::

+ #kernel
+ IpInReceives 1 0.0
+ IpInDelivers 1 0.0
+ IpOutRequests 1 0.0

+ IpExtInOctets 84 0.0
+ IpExtOutOctets 84 0.0
+ IpExtInNoECTPkts 1 0.0
+
+The Linux server sent an ICMP Echo packet, so IpOutRequests,
+IcmpOutMsgs, IcmpOutEchos and IcmpMsgOutType8 were increased 1. The
+server got ICMP Echo Reply from 8.8.8.8, so IpInReceives, IcmpInMsgs,
+IcmpInEchoReps and IcmpMsgInType0 were increased 1. The ICMP Echo Reply
+was passed to the ICMP layer via IP layer, so IpInDelivers was
+increased 1. The default ping data size is 48, so an ICMP Echo packet
+and its corresponding Echo Reply packet are constructed by:
+
+* 14 bytes MAC header
+* 20 bytes IP header
+* 16 bytes ICMP header
+* 48 bytes data (default value of the ping command)
+
+So the IpExtInOctets and IpExtOutOctets are 20+16+48=84.
+
+tcp 3-way handshake
+-------------------
+On server side, we run::
+
+ nstatuser@nstat-b:~$ nc -lknv 0.0.0.0 9000
+ Listening on [0.0.0.0] (family 0, port 9000)
+
+On client side, we run::
+
+ nstatuser@nstat-a:~$ nc -nv 192.168.122.251 9000
+ Connection to 192.168.122.251 9000 port [tcp/*] succeeded!
+
+The server listened on tcp 9000 port, the client connected to it, they
+completed the 3-way handshake.
+
+On server side, we can find below nstat output::
+
+ nstatuser@nstat-b:~$ nstat | grep -i tcp
+ TcpPassiveOpens 1 0.0
+ TcpInSegs 2 0.0
+ TcpOutSegs 1 0.0
+ TcpExtTCPPureAcks 1 0.0
+
+On client side, we can find below nstat output::
+
+ nstatuser@nstat-a:~$ nstat | grep -i tcp
+ TcpActiveOpens 1 0.0
+ TcpInSegs 1 0.0
+ TcpOutSegs 2 0.0
+
+When the server received the first SYN, it replied a SYN+ACK, and came into
+SYN-RCVD state, so TcpPassiveOpens increased 1. The server received
+SYN, sent SYN+ACK, received ACK, so server sent 1 packet, received 2
+packets, TcpInSegs increased 2, TcpOutSegs increased 1. The last ACK
+of the 3-way handshake is a pure ACK without data, so
+TcpExtTCPPureAcks increased 1.
+
+When the client sent SYN, the client came into the SYN-SENT state, so
+TcpActiveOpens increased 1, the client sent SYN, received SYN+ACK, sent
+ACK, so client sent 2 packets, received 1 packet, TcpInSegs increased
+1, TcpOutSegs increased 2.

+
+Compare the first client-side nstat and the second client-side nstat,
+we could find one difference: the first one had a 'TcpExtTCPPureAcks',
+but the second one had a 'TcpExtTCPHPAcks'. The first server-side
+nstat and the second server-side nstat had a difference too: the
+second server-side nstat had a TcpExtTCPHPHits, but the first
+server-side nstat didn't have it. The network traffic patterns were
+exactly the same: the client sent a packet to the server, the server
+replied an ACK. But kernel handled them in different ways. When the
+TCP window scale option is not used, kernel will try to enable fast
+path immediately when the connection comes into the established state,
+but if the TCP window scale option is used, kernel will disable the
+fast path at first, and try to enable it after kerenl receives
+packets. We could use the 'ss' command to verify whether the window
+scale option is used. e.g. run below command on either server or
+client::
+
+ nstatuser@nstat-a:~$ ss -o state established -i '( dport = :9000 or sport = :9000 )
+ Netid Recv-Q Send-Q Local Address:Port Peer Address:Port
+ tcp 0 0 192.168.122.250:40654 192.168.122.251:9000
+ ts sack cubic wscale:7,7 rto:204 rtt:0.98/0.49 mss:1448 pmtu:1500 rcvmss:536 advmss:1448 cwnd:10 bytes_acked:1 segs_out:2 segs_in:1 send 118.2Mbps lastsnd:46572 lastrcv:46572 lastack:46572 pacing_rate 236.4Mbps rcv_space:29200 rcv_ssthresh:29200 minrtt:0.98
+
+The 'wscale:7,7' means both server and client set the window scale
+option to 7. Now we could explain the nstat output in our test:
+
+In the first nstat output of client side, the client sent a packet, server
+reply an ACK, when kernel handled this ACK, the fast path was not
+enabled, so the ACK was counted into 'TcpExtTCPPureAcks'.
+
+In the second nstat output of client side, the client sent a packet again,
+and received another ACK from the server, in this time, the fast path is
+enabled, and the ACK was qualified for fast path, so it was handled by
+the fast path, so this ACK was counted into TcpExtTCPHPAcks.
+
+In the first nstat output of server side, fast path was not enabled,
+so there was no 'TcpExtTCPHPHits'.
+
+In the second nstat output of server side, the fast path was enabled,
+and the packet received from client qualified for fast path, so it
+was counted into 'TcpExtTCPHPHits'.
+
+TcpExtTCPAbortOnClose
+---------------------
+On the server side, we run below python script::
+
+ import socket
+ import time
+
+ port = 9000
+
+ s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
+ s.bind(('0.0.0.0', port))
+ s.listen(1)
+ sock, addr = s.accept()
+ while True:
+ time.sleep(9999999)
+
+This python script listen on 9000 port, but doesn't read anything from
+the connection.
+
+On the client side, we send the string "hello" by nc::
+
+ nstatuser@nstat-a:~$ echo "hello" | nc nstat-b 9000
+
+Then, we come back to the server side, the server has received the "hello"
+packet, and the TCP layer has acked this packet, but the application didn't
+read it yet. We type Ctrl-C to terminate the server script. Then we
+could find TcpExtTCPAbortOnClose increased 1 on the server side::
+
+ nstatuser@nstat-b:~$ nstat | grep -i abort
+ TcpExtTCPAbortOnClose 1 0.0
+
+If we run tcpdump on the server side, we could find the server sent a
+RST after we type Ctrl-C.
+
+TcpExtTCPAbortOnMemory and TcpExtTCPAbortOnTimeout
+---------------------------------------------------
+Below is an example which let the orphan socket count be higher than
+net.ipv4.tcp_max_orphans.
+Change tcp_max_orphans to a smaller value on client::
+
+ sudo bash -c "echo 10 > /proc/sys/net/ipv4/tcp_max_orphans"
+
+Client code (create 64 connection to server)::
+
+ nstatuser@nstat-a:~$ cat client_orphan.py
+ import socket
+ import time
+
+ server = 'nstat-b' # server address
+ port = 9000
+
+ count = 64
+
+ connection_list = []
+
+ for i in range(64):
+ s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
+ s.connect((server, port))
+ connection_list.append(s)
+ print("connection_count: %d" % len(connection_list))
+
+ while True:
+ time.sleep(99999)
+
+Server code (accept 64 connection from client)::
+
+ nstatuser@nstat-b:~$ cat server_orphan.py
+ import socket
+ import time
+
+ port = 9000
+ count = 64
+
+ s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
+ s.bind(('0.0.0.0', port))
+ s.listen(count)
+ connection_list = []
+ while True:
+ sock, addr = s.accept()
+ connection_list.append((sock, addr))
+ print("connection_count: %d" % len(connection_list))
+
+Run the python scripts on server and client.
+
+On server::
+
+ python3 server_orphan.py
+
+On client::
+
+ python3 client_orphan.py
+
+Run iptables on server::
+
+ sudo iptables -A INPUT -i ens3 -p tcp --destination-port 9000 -j DROP
+
+Type Ctrl-C on client, stop client_orphan.py.
+
+Check TcpExtTCPAbortOnMemory on client::
+
+ nstatuser@nstat-a:~$ nstat | grep -i abort
+ TcpExtTCPAbortOnMemory 54 0.0
+
+Check orphane socket count on client::
+
+ nstatuser@nstat-a:~$ ss -s
+ Total: 131 (kernel 0)
+ TCP: 14 (estab 1, closed 0, orphaned 10, synrecv 0, timewait 0/0), ports 0
+
+ Transport Total IP IPv6
+ * 0 - -
+ RAW 1 0 1
+ UDP 1 1 0
+ TCP 14 13 1
+ INET 16 14 2
+ FRAG 0 0 0
+
+The explanation of the test: after run server_orphan.py and
+client_orphan.py, we set up 64 connections between server and
+client. Run the iptables command, the server will drop all packets from
+the client, type Ctrl-C on client_orphan.py, the system of the client
+would try to close these connections, and before they are closed
+gracefully, these connections became orphan sockets. As the iptables
+of the server blocked packets from the client, the server won't receive fin
+from the client, so all connection on clients would be stuck on FIN_WAIT_1
+stage, so they will keep as orphan sockets until timeout. We have echo
+10 to /proc/sys/net/ipv4/tcp_max_orphans, so the client system would
+only keep 10 orphan sockets, for all other orphan sockets, the client
+system sent RST for them and delete them. We have 64 connections, so
+the 'ss -s' command shows the system has 10 orphan sockets, and the
+value of TcpExtTCPAbortOnMemory was 54.
+
+An additional explanation about orphan socket count: You could find the
+exactly orphan socket count by the 'ss -s' command, but when kernel
+decide whither increases TcpExtTCPAbortOnMemory and sends RST, kernel
+doesn't always check the exactly orphan socket count. For increasing
+performance, kernel checks an approximate count firstly, if the
+approximate count is more than tcp_max_orphans, kernel checks the
+exact count again. So if the approximate count is less than
+tcp_max_orphans, but exactly count is more than tcp_max_orphans, you
+would find TcpExtTCPAbortOnMemory is not increased at all. If
+tcp_max_orphans is large enough, it won't occur, but if you decrease
+tcp_max_orphans to a small value like our test, you might find this
+issue. So in our test, the client set up 64 connections although the
+tcp_max_orphans is 10. If the client only set up 11 connections, we
+can't find the change of TcpExtTCPAbortOnMemory.
+
+Continue the previous test, we wait for several minutes. Because of the
+iptables on the server blocked the traffic, the server wouldn't receive
+fin, and all the client's orphan sockets would timeout on the
+FIN_WAIT_1 state finally. So we wait for a few minutes, we could find
+10 timeout on the client::
+
+ nstatuser@nstat-a:~$ nstat | grep -i abort
+ TcpExtTCPAbortOnTimeout 10 0.0
+
+TcpExtTCPAbortOnLinger
+----------------------
+The server side code::
+
+ nstatuser@nstat-b:~$ cat server_linger.py
+ import socket
+ import time
+
+ port = 9000
+
+ s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
+ s.bind(('0.0.0.0', port))
+ s.listen(1)
+ sock, addr = s.accept()
+ while True:
+ time.sleep(9999999)
+
+The client side code::
+
+ nstatuser@nstat-a:~$ cat client_linger.py
+ import socket
+ import struct
+
+ server = 'nstat-b' # server address
+ port = 9000
+
+ s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
+ s.setsockopt(socket.SOL_SOCKET, socket.SO_LINGER, struct.pack('ii', 1, 10))
+ s.setsockopt(socket.SOL_TCP, socket.TCP_LINGER2, struct.pack('i', -1))
+ s.connect((server, port))
+ s.close()
+
+Run server_linger.py on server::
+
+ nstatuser@nstat-b:~$ python3 server_linger.py
+
+Run client_linger.py on client::
+
+ nstatuser@nstat-a:~$ python3 client_linger.py
+
+After run client_linger.py, check the output of nstat::
+
+ nstatuser@nstat-a:~$ nstat | grep -i abort
+ TcpExtTCPAbortOnLinger 1 0.0
+
+TcpExtTCPRcvCoalesce
+--------------------
+On the server, we run a program which listen on TCP port 9000, but
+doesn't read any data::
+
+ import socket
+ import time
+ port = 9000
+ s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
+ s.bind(('0.0.0.0', port))
+ s.listen(1)
+ sock, addr = s.accept()
+ while True:
+ time.sleep(9999999)
+
+Save the above code as server_coalesce.py, and run::
+
+ python3 server_coalesce.py
+
+On the client, save below code as client_coalesce.py::
+
+ import socket
+ server = 'nstat-b'
+ port = 9000
+ s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
+ s.connect((server, port))
+
+Run::
+
+ nstatuser@nstat-a:~$ python3 -i client_coalesce.py
+
+We use '-i' to come into the interactive mode, then a packet::
+
+ >>> s.send(b'foo')
+ 3
+
+Send a packet again::
+
+ >>> s.send(b'bar')
+ 3
+
+On the server, run nstat::
+
+ ubuntu@nstat-b:~$ nstat
+ #kernel
+ IpInReceives 2 0.0
+ IpInDelivers 2 0.0
+ IpOutRequests 2 0.0
+ TcpInSegs 2 0.0
+ TcpOutSegs 2 0.0
+ TcpExtTCPRcvCoalesce 1 0.0
+ IpExtInOctets 110 0.0
+ IpExtOutOctets 104 0.0
+ IpExtInNoECTPkts 2 0.0
+
+The client sent two packets, server didn't read any data. When
+the second packet arrived at server, the first packet was still in
+the receiving queue. So the TCP layer merged the two packets, and we
+could find the TcpExtTCPRcvCoalesce increased 1.
+
+TcpExtListenOverflows and TcpExtListenDrops
+-------------------------------------------
+On server, run the nc command, listen on port 9000::
+
+ nstatuser@nstat-b:~$ nc -lkv 0.0.0.0 9000
+ Listening on [0.0.0.0] (family 0, port 9000)
+
+On client, run 3 nc commands in different terminals::
+
+ nstatuser@nstat-a:~$ nc -v nstat-b 9000
+ Connection to nstat-b 9000 port [tcp/*] succeeded!
+
+The nc command only accepts 1 connection, and the accept queue length
+is 1. On current linux implementation, set queue length to n means the
+actual queue length is n+1. Now we create 3 connections, 1 is accepted
+by nc, 2 in accepted queue, so the accept queue is full.
+
+Before running the 4th nc, we clean the nstat history on the server::
+
+ nstatuser@nstat-b:~$ nstat -n
+
+Run the 4th nc on the client::
+
+ nstatuser@nstat-a:~$ nc -v nstat-b 9000
+
+If the nc server is running on kernel 4.10 or higher version, you
+won't see the "Connection to ... succeeded!" string, because kernel
+will drop the SYN if the accept queue is full. If the nc client is running
+on an old kernel, you would see that the connection is succeeded,
+because kernel would complete the 3 way handshake and keep the socket
+on half open queue. I did the test on kernel 4.15. Below is the nstat
+on the server::
+
+ nstatuser@nstat-b:~$ nstat
+ #kernel
+ IpInReceives 4 0.0
+ IpInDelivers 4 0.0
+ TcpInSegs 4 0.0
+ TcpExtListenOverflows 4 0.0
+ TcpExtListenDrops 4 0.0
+ IpExtInOctets 240 0.0
+ IpExtInNoECTPkts 4 0.0
+
+Both TcpExtListenOverflows and TcpExtListenDrops were 4. If the time
+between the 4th nc and the nstat was longer, the value of
+TcpExtListenOverflows and TcpExtListenDrops would be larger, because
+the SYN of the 4th nc was dropped, the client was retrying.
+
+IpInAddrErrors, IpExtInNoRoutes and IpOutNoRoutes
+-------------------------------------------------
+server A IP address: 192.168.122.250
+server B IP address: 192.168.122.251
+Prepare on server A, add a route to server B::
+
+ $ sudo ip route add 8.8.8.8/32 via 192.168.122.251
+
+Prepare on server B, disable send_redirects for all interfaces::
+
+ $ sudo sysctl -w net.ipv4.conf.all.send_redirects=0
+ $ sudo sysctl -w net.ipv4.conf.ens3.send_redirects=0
+ $ sudo sysctl -w net.ipv4.conf.lo.send_redirects=0
+ $ sudo sysctl -w net.ipv4.conf.default.send_redirects=0
+
+We want to let sever A send a packet to 8.8.8.8, and route the packet
+to server B. When server B receives such packet, it might send a ICMP
+Redirect message to server A, set send_redirects to 0 will disable
+this behavior.
+
+First, generate InAddrErrors. On server B, we disable IP forwarding::
+
+ $ sudo sysctl -w net.ipv4.conf.all.forwarding=0
+
+On server A, we send packets to 8.8.8.8::
+
+ $ nc -v 8.8.8.8 53
+
+On server B, we check the output of nstat::
+
+ $ nstat
+ #kernel
+ IpInReceives 3 0.0
+ IpInAddrErrors 3 0.0
+ IpExtInOctets 180 0.0
+ IpExtInNoECTPkts 3 0.0
+
+As we have let server A route 8.8.8.8 to server B, and we disabled IP
+forwarding on server B, Server A sent packets to server B, then server B
+dropped packets and increased IpInAddrErrors. As the nc command would
+re-send the SYN packet if it didn't receive a SYN+ACK, we could find
+multiple IpInAddrErrors.
+
+Second, generate IpExtInNoRoutes. On server B, we enable IP
+forwarding::
+
+ $ sudo sysctl -w net.ipv4.conf.all.forwarding=1
+
+Check the route table of server B and remove the default route::
+
+ $ ip route show
+ default via 192.168.122.1 dev ens3 proto static
+ 192.168.122.0/24 dev ens3 proto kernel scope link src 192.168.122.251
+ $ sudo ip route delete default via 192.168.122.1 dev ens3 proto static
+
+On server A, we contact 8.8.8.8 again::
+
+ $ nc -v 8.8.8.8 53
+ nc: connect to 8.8.8.8 port 53 (tcp) failed: Network is unreachable
+
+On server B, run nstat::
+
+ $ nstat
+ #kernel
+ IpInReceives 1 0.0
+ IpOutRequests 1 0.0
+ IcmpOutMsgs 1 0.0
+ IcmpOutDestUnreachs 1 0.0
+ IcmpMsgOutType3 1 0.0
+ IpExtInNoRoutes 1 0.0
+ IpExtInOctets 60 0.0
+ IpExtOutOctets 88 0.0
+ IpExtInNoECTPkts 1 0.0
+
+We enabled IP forwarding on server B, when server B received a packet
+which destination IP address is 8.8.8.8, server B will try to forward
+this packet. We have deleted the default route, there was no route for
+8.8.8.8, so server B increase IpExtInNoRoutes and sent the "ICMP
+Destination Unreachable" message to server A.
+
+Third, generate IpOutNoRoutes. Run ping command on server B::
+
+ $ ping -c 1 8.8.8.8
+ connect: Network is unreachable
+
+Run nstat on server B::
+
+ $ nstat
+ #kernel
+ IpOutNoRoutes 1 0.0
+
+We have deleted the default route on server B. Server B couldn't find
+a route for the 8.8.8.8 IP address, so server B increased
+IpOutNoRoutes.
+
+TcpExtTCPACKSkippedSynRecv
+--------------------------
+In this test, we send 3 same SYN packets from client to server. The
+first SYN will let server create a socket, set it to Syn-Recv status,
+and reply a SYN/ACK. The second SYN will let server reply the SYN/ACK
+again, and record the reply time (the duplicate ACK reply time). The
+third SYN will let server check the previous duplicate ACK reply time,
+and decide to skip the duplicate ACK, then increase the
+TcpExtTCPACKSkippedSynRecv counter.
+
+Run tcpdump to capture a SYN packet::
+
+ nstatuser@nstat-a:~$ sudo tcpdump -c 1 -w /tmp/syn.pcap port 9000
+ tcpdump: listening on ens3, link-type EN10MB (Ethernet), capture size 262144 bytes
+
+Open another terminal, run nc command::
+
+ nstatuser@nstat-a:~$ nc nstat-b 9000
+
+As the nstat-b didn't listen on port 9000, it should reply a RST, and
+the nc command exited immediately. It was enough for the tcpdump
+command to capture a SYN packet. A linux server might use hardware
+offload for the TCP checksum, so the checksum in the /tmp/syn.pcap
+might be not correct. We call tcprewrite to fix it::
+
+ nstatuser@nstat-a:~$ tcprewrite --infile=/tmp/syn.pcap --outfile=/tmp/syn_fixcsum.pcap --fixcsum
+
+On nstat-b, we run nc to listen on port 9000::
+
+ nstatuser@nstat-b:~$ nc -lkv 9000
+ Listening on [0.0.0.0] (family 0, port 9000)
+
+On nstat-a, we blocked the packet from port 9000, or nstat-a would send
+RST to nstat-b::
+
+ nstatuser@nstat-a:~$ sudo iptables -A INPUT -p tcp --sport 9000 -j DROP
+
+Send 3 SYN repeatly to nstat-b::
+
+ nstatuser@nstat-a:~$ for i in {1..3}; do sudo tcpreplay -i ens3 /tmp/syn_fixcsum.pcap; done
+
+Check snmp cunter on nstat-b::
+
+ nstatuser@nstat-b:~$ nstat | grep -i skip
+ TcpExtTCPACKSkippedSynRecv 1 0.0
+
+As we expected, TcpExtTCPACKSkippedSynRecv is 1.
+
+TcpExtTCPACKSkippedPAWS
+-----------------------
+To trigger PAWS, we could send an old SYN.
+
+On nstat-b, let nc listen on port 9000::
+
+ nstatuser@nstat-b:~$ nc -lkv 9000
+ Listening on [0.0.0.0] (family 0, port 9000)
+
+On nstat-a, run tcpdump to capture a SYN::
+
+ nstatuser@nstat-a:~$ sudo tcpdump -w /tmp/paws_pre.pcap -c 1 port 9000
+ tcpdump: listening on ens3, link-type EN10MB (Ethernet), capture size 262144 bytes
+
+On nstat-a, run nc as a client to connect nstat-b::
+
+ nstatuser@nstat-a:~$ nc -v nstat-b 9000
+ Connection to nstat-b 9000 port [tcp/*] succeeded!
+
+Now the tcpdump has captured the SYN and exit. We should fix the
+checksum::
+
+ nstatuser@nstat-a:~$ tcprewrite --infile /tmp/paws_pre.pcap --outfile /tmp/paws.pcap --fixcsum
+
+Send the SYN packet twice::
+
+ nstatuser@nstat-a:~$ for i in {1..2}; do sudo tcpreplay -i ens3 /tmp/paws.pcap; done
+
+On nstat-b, check the snmp counter::
+
+ nstatuser@nstat-b:~$ nstat | grep -i skip
+ TcpExtTCPACKSkippedPAWS 1 0.0
+
+We sent two SYN via tcpreplay, both of them would let PAWS check
+failed, the nstat-b replied an ACK for the first SYN, skipped the ACK
+for the second SYN, and updated TcpExtTCPACKSkippedPAWS.
+
+TcpExtTCPACKSkippedSeq
+----------------------
+To trigger TcpExtTCPACKSkippedSeq, we send packets which have valid
+timestamp (to pass PAWS check) but the sequence number is out of
+window. The linux TCP stack would avoid to skip if the packet has
+data, so we need a pure ACK packet. To generate such a packet, we
+could create two sockets: one on port 9000, another on port 9001. Then
+we capture an ACK on port 9001, change the source/destination port
+numbers to match the port 9000 socket. Then we could trigger
+TcpExtTCPACKSkippedSeq via this packet.
+
+On nstat-b, open two terminals, run two nc commands to listen on both
+port 9000 and port 9001::
+
+ nstatuser@nstat-b:~$ nc -lkv 9000
+ Listening on [0.0.0.0] (family 0, port 9000)
+
+ nstatuser@nstat-b:~$ nc -lkv 9001
+ Listening on [0.0.0.0] (family 0, port 9001)
+
+On nstat-a, run two nc clients::
+
+ nstatuser@nstat-a:~$ nc -v nstat-b 9000
+ Connection to nstat-b 9000 port [tcp/*] succeeded!
+
+ nstatuser@nstat-a:~$ nc -v nstat-b 9001
+ Connection to nstat-b 9001 port [tcp/*] succeeded!
+
+On nstat-a, run tcpdump to capture an ACK::
+
+ nstatuser@nstat-a:~$ sudo tcpdump -w /tmp/seq_pre.pcap -c 1 dst port 9001
+ tcpdump: listening on ens3, link-type EN10MB (Ethernet), capture size 262144 bytes
+
+On nstat-b, send a packet via the port 9001 socket. E.g. we sent a
+string 'foo' in our example::
+
+ nstatuser@nstat-b:~$ nc -lkv 9001
+ Listening on [0.0.0.0] (family 0, port 9001)
+ Connection from nstat-a 42132 received!
+ foo
+
+On nstat-a, the tcpdump should have caputred the ACK. We should check
+the source port numbers of the two nc clients::
+
+ nstatuser@nstat-a:~$ ss -ta '( dport = :9000 || dport = :9001 )' | tee
+ State Recv-Q Send-Q Local Address:Port Peer Address:Port
+ ESTAB 0 0 192.168.122.250:50208 192.168.122.251:9000
+ ESTAB 0 0 192.168.122.250:42132 192.168.122.251:9001
+
+Run tcprewrite, change port 9001 to port 9000, chagne port 42132 to
+port 50208::
+
+ nstatuser@nstat-a:~$ tcprewrite --infile /tmp/seq_pre.pcap --outfile /tmp/seq.pcap -r 9001:9000 -r 42132:50208 --fixcsum
+
+Now the /tmp/seq.pcap is the packet we need. Send it to nstat-b::
+
+ nstatuser@nstat-a:~$ for i in {1..2}; do sudo tcpreplay -i ens3 /tmp/seq.pcap; done
+
+Check TcpExtTCPACKSkippedSeq on nstat-b::
+
+ nstatuser@nstat-b:~$ nstat | grep -i skip
+ TcpExtTCPACKSkippedSeq 1 0.0

+NVDIMM SECURITY
+===============
+
+1. Introduction
+---------------
+
+With the introduction of Intel Device Specific Methods (DSM) v1.8
+specification [1], security DSMs are introduced. The spec added the following
+security DSMs: "get security state", "set passphrase", "disable passphrase",
+"unlock unit", "freeze lock", "secure erase", and "overwrite". A security_ops
+data structure has been added to struct dimm in order to support the security
+operations and generic APIs are exposed to allow vendor neutral operations.
+
+2. Sysfs Interface
+------------------
+The "security" sysfs attribute is provided in the nvdimm sysfs directory. For
+example:
+/sys/devices/LNXSYSTM:00/LNXSYBUS:00/ACPI0012:00/ndbus0/nmem0/security
+
+The "show" attribute of that attribute will display the security state for
+that DIMM. The following states are available: disabled, unlocked, locked,
+frozen, and overwrite. If security is not supported, the sysfs attribute
+will not be visible.
+
+The "store" attribute takes several commands when it is being written to
+in order to support some of the security functionalities:
+update <old_keyid> <new_keyid> - enable or update passphrase.
+disable <keyid> - disable enabled security and remove key.
+freeze - freeze changing of security states.
+erase <keyid> - delete existing user encryption key.
+overwrite <keyid> - wipe the entire nvdimm.
+master_update <keyid> <new_keyid> - enable or update master passphrase.
+master_erase <keyid> - delete existing user encryption key.
+
+3. Key Management
+-----------------
+
+The key is associated to the payload by the DIMM id. For example:
+# cat /sys/devices/LNXSYSTM:00/LNXSYBUS:00/ACPI0012:00/ndbus0/nmem0/nfit/id
+8089-a2-1740-00000133
+The DIMM id would be provided along with the key payload (passphrase) to
+the kernel.
+
+The security keys are managed on the basis of a single key per DIMM. The
+key "passphrase" is expected to be 32bytes long. This is similar to the ATA
+security specification [2]. A key is initially acquired via the request_key()
+kernel API call during nvdimm unlock. It is up to the user to make sure that
+all the keys are in the kernel user keyring for unlock.
+
+A nvdimm encrypted-key of format enc32 has the description format of:
+nvdimm:<bus-provider-specific-unique-id>
+
+See file ``Documentation/security/keys/trusted-encrypted.rst`` for creating
+encrypted-keys of enc32 format. TPM usage with a master trusted key is
+preferred for sealing the encrypted-keys.
+
+4. Unlocking
+------------
+When the DIMMs are being enumerated by the kernel, the kernel will attempt to
+retrieve the key from the kernel user keyring. This is the only time
+a locked DIMM can be unlocked. Once unlocked, the DIMM will remain unlocked
+until reboot. Typically an entity (i.e. shell script) will inject all the
+relevant encrypted-keys into the kernel user keyring during the initramfs phase.
+This provides the unlock function access to all the related keys that contain
+the passphrase for the respective nvdimms. It is also recommended that the
+keys are injected before libnvdimm is loaded by modprobe.
+
+5. Update
+---------
+When doing an update, it is expected that the existing key is removed from
+the kernel user keyring and reinjected as different (old) key. It's irrelevant
+what the key description is for the old key since we are only interested in the
+keyid when doing the update operation. It is also expected that the new key
+is injected with the description format described from earlier in this
+document. The update command written to the sysfs attribute will be with
+the format:
+update <old keyid> <new keyid>
+
+If there is no old keyid due to a security enabling, then a 0 should be
+passed in.
+
+6. Freeze
+---------
+The freeze operation does not require any keys. The security config can be
+frozen by a user with root privelege.
+
+7. Disable
+----------
+The security disable command format is:
+disable <keyid>
+
+An key with the current passphrase payload that is tied to the nvdimm should be
+in the kernel user keyring.
+
+8. Secure Erase
+---------------
+The command format for doing a secure erase is:
+erase <keyid>
+
+An key with the current passphrase payload that is tied to the nvdimm should be
+in the kernel user keyring.
+
+9. Overwrite
+------------
+The command format for doing an overwrite is:
+overwrite <keyid>
+
+Overwrite can be done without a key if security is not enabled. A key serial
+of 0 can be passed in to indicate no key.
+
+The sysfs attribute "security" can be polled to wait on overwrite completion.
+Overwrite can last tens of minutes or more depending on nvdimm size.
+
+An encrypted-key with the current user passphrase that is tied to the nvdimm
+should be injected and its keyid should be passed in via sysfs.
+
+10. Master Update
+-----------------
+The command format for doing a master update is:
+update <old keyid> <new keyid>
+
+The operating mechanism for master update is identical to update except the
+master passphrase key is passed to the kernel. The master passphrase key
+is just another encrypted-key.
+
+This command is only available when security is disabled.
+
+11. Master Erase
+----------------
+The command format for doing a master erase is:
+master_erase <current keyid>
+
+This command has the same operating mechanism as erase except the master
+passphrase key is passed to the kernel. The master passphrase key is just
+another encrypted-key.
+
+This command is only available when the master security is enabled, indicated
+by the extended security status.

+Cavium ThunderX2 SoC Performance Monitoring Unit (PMU UNCORE)
+=============================================================
+
+The ThunderX2 SoC PMU consists of independent, system-wide, per-socket
+PMUs such as the Level 3 Cache (L3C) and DDR4 Memory Controller (DMC).
+
+The DMC has 8 interleaved channels and the L3C has 16 interleaved tiles.
+Events are counted for the default channel (i.e. channel 0) and prorated
+to the total number of channels/tiles.
+
+The DMC and L3C support up to 4 counters. Counters are independently
+programmable and can be started and stopped individually. Each counter
+can be set to a different event. Counters are 32-bit and do not support
+an overflow interrupt; they are read every 2 seconds.
+
+PMU UNCORE (perf) driver:
+
+The thunderx2_pmu driver registers per-socket perf PMUs for the DMC and
+L3C devices. Each PMU can be used to count up to 4 events
+simultaneously. The PMUs provide a description of their available events
+and configuration options under sysfs, see
+/sys/devices/uncore_<l3c_S/dmc_S/>; S is the socket id.
+
+The driver does not support sampling, therefore "perf record" will not
+work. Per-task perf sessions are also not supported.

+ ====================
+ Energy Model of CPUs
+ ====================
+
+1. Overview
+-----------
+
+The Energy Model (EM) framework serves as an interface between drivers knowing
+the power consumed by CPUs at various performance levels, and the kernel
+subsystems willing to use that information to make energy-aware decisions.
+
+The source of the information about the power consumed by CPUs can vary greatly
+from one platform to another. These power costs can be estimated using
+devicetree data in some cases. In others, the firmware will know better.
+Alternatively, userspace might be best positioned. And so on. In order to avoid
+each and every client subsystem to re-implement support for each and every
+possible source of information on its own, the EM framework intervenes as an
+abstraction layer which standardizes the format of power cost tables in the
+kernel, hence enabling to avoid redundant work.
+
+The figure below depicts an example of drivers (Arm-specific here, but the
+approach is applicable to any architecture) providing power costs to the EM
+framework, and interested clients reading the data from it.

+ +--------------+ +---------------+ +--------------+
+
+The EM framework manages power cost tables per 'performance domain' in the
+system. A performance domain is a group of CPUs whose performance is scaled
+together. Performance domains generally have a 1-to-1 mapping with CPUFreq
+policies. All CPUs in a performance domain are required to have the same
+micro-architecture. CPUs in different performance domains can have different

+
+2. Core APIs
+------------
+
+ 2.1 Config options
+
+CONFIG_ENERGY_MODEL must be enabled to use the EM framework.
+
+
+ 2.2 Registration of performance domains
+
+Drivers are expected to register performance domains into the EM framework by
+calling the following API:
+
+ int em_register_perf_domain(cpumask_t *span, unsigned int nr_states,
+ struct em_data_callback *cb);
+
+Drivers must specify the CPUs of the performance domains using the cpumask
+argument, and provide a callback function returning <frequency, power> tuples
+for each capacity state. The callback function provided by the driver is free
+to fetch data from any relevant location (DT, firmware, ...), and by any mean
+deemed necessary. See Section 3. for an example of driver implementing this
+callback, and kernel/power/energy_model.c for further documentation on this
+API.
+
+
+ 2.3 Accessing performance domains
+
+Subsystems interested in the energy model of a CPU can retrieve it using the
+em_cpu_get() API. The energy model tables are allocated once upon creation of
+the performance domains, and kept in memory untouched.
+
+The energy consumed by a performance domain can be estimated using the
+em_pd_energy() API. The estimation is performed assuming that the schedutil
+CPUfreq governor is in use.
+
+More details about the above APIs can be found in include/linux/energy_model.h.
+
+
+3. Example driver
+-----------------
+
+This section provides a simple example of a CPUFreq driver registering a
+performance domain in the Energy Model framework using the (fake) 'foo'
+protocol. The driver implements an est_power() function to be provided to the
+EM framework.
+
+ -> drivers/cpufreq/foo_cpufreq.c

-17) Don't re-invent the kernel macros
+17) Using bool
+--------------
+
+The Linux kernel bool type is an alias for the C99 _Bool type. bool values can
+only evaluate to 0 or 1, and implicit or explicit conversion to bool
+automatically converts the value to true or false. When using bool types the
+!! construction is not needed, which eliminates a class of bugs.
+
+When working with bool values the true and false definitions should be used
+instead of 1 and 0.
+
+bool function return types and stack variables are always fine to use whenever
+appropriate. Use of bool is encouraged to improve readability and is often a
+better option than 'int' for storing boolean values.
+
+Do not use bool if cache line layout or size of the value matters, as its size
+and alignment varies based on the compiled architecture. Structures that are
+optimized for alignment and size should not use bool.
+
+If a structure has many true/false values, consider consolidating them into a
+bitfield with 1 bit members, or using an appropriate fixed width type, such as
+u8.
+
+Similarly for function arguments, many true/false values can be consolidated
+into a single bitwise 'flags' argument and 'flags' can often be a more
+readable alternative if the call-sites have naked true/false constants.
+
+Otherwise limited use of bool in structures and arguments can improve
+readability.

+ =======================
+ Energy Aware Scheduling
+ =======================
+
+1. Introduction
+---------------
+
+Energy Aware Scheduling (or EAS) gives the scheduler the ability to predict
+the impact of its decisions on the energy consumed by CPUs. EAS relies on an
+Energy Model (EM) of the CPUs to select an energy efficient CPU for each task,
+with a minimal impact on throughput. This document aims at providing an
+introduction on how EAS works, what are the main design decisions behind it, and
+details what is needed to get it to run.
+
+Before going any further, please note that at the time of writing:
+
+ /!\ EAS does not support platforms with symmetric CPU topologies /!\
+
+EAS operates only on heterogeneous CPU topologies (such as Arm big.LITTLE)
+because this is where the potential for saving energy through scheduling is
+the highest.
+
+The actual EM used by EAS is _not_ maintained by the scheduler, but by a
+dedicated framework. For details about this framework and what it provides,
+please refer to its documentation (see Documentation/power/energy-model.txt).
+
+
+2. Background and Terminology
+-----------------------------
+
+To make it clear from the start:
+ - energy = [joule] (resource like a battery on powered devices)
+ - power = energy/time = [joule/second] = [watt]
+
+The goal of EAS is to minimize energy, while still getting the job done. That
+is, we want to maximize:
+
+ performance [inst/s]
+ --------------------
+ power [W]
+
+which is equivalent to minimizing:
+
+ energy [J]
+ -----------
+ instruction
+
+while still getting 'good' performance. It is essentially an alternative
+optimization objective to the current performance-only objective for the
+scheduler. This alternative considers two objectives: energy-efficiency and
+performance.
+
+The idea behind introducing an EM is to allow the scheduler to evaluate the
+implications of its decisions rather than blindly applying energy-saving
+techniques that may have positive effects only on some platforms. At the same
+time, the EM must be as simple as possible to minimize the scheduler latency
+impact.
+
+In short, EAS changes the way CFS tasks are assigned to CPUs. When it is time
+for the scheduler to decide where a task should run (during wake-up), the EM
+is used to break the tie between several good CPU candidates and pick the one
+that is predicted to yield the best energy consumption without harming the
+system's throughput. The predictions made by EAS rely on specific elements of
+knowledge about the platform's topology, which include the 'capacity' of CPUs,
+and their respective energy costs.
+
+
+3. Topology information
+-----------------------
+
+EAS (as well as the rest of the scheduler) uses the notion of 'capacity' to
+differentiate CPUs with different computing throughput. The 'capacity' of a CPU
+represents the amount of work it can absorb when running at its highest
+frequency compared to the most capable CPU of the system. Capacity values are
+normalized in a 1024 range, and are comparable with the utilization signals of
+tasks and CPUs computed by the Per-Entity Load Tracking (PELT) mechanism. Thanks
+to capacity and utilization values, EAS is able to estimate how big/busy a
+task/CPU is, and to take this into consideration when evaluating performance vs
+energy trade-offs. The capacity of CPUs is provided via arch-specific code
+through the arch_scale_cpu_capacity() callback.
+
+The rest of platform knowledge used by EAS is directly read from the Energy
+Model (EM) framework. The EM of a platform is composed of a power cost table
+per 'performance domain' in the system (see Documentation/power/energy-model.txt
+for futher details about performance domains).
+
+The scheduler manages references to the EM objects in the topology code when the
+scheduling domains are built, or re-built. For each root domain (rd), the
+scheduler maintains a singly linked list of all performance domains intersecting
+the current rd->span. Each node in the list contains a pointer to a struct
+em_perf_domain as provided by the EM framework.
+
+The lists are attached to the root domains in order to cope with exclusive
+cpuset configurations. Since the boundaries of exclusive cpusets do not
+necessarily match those of performance domains, the lists of different root
+domains can contain duplicate elements.
+
+Example 1.
+ Let us consider a platform with 12 CPUs, split in 3 performance domains
+ (pd0, pd4 and pd8), organized as follows:
+
+ CPUs: 0 1 2 3 4 5 6 7 8 9 10 11
+ PDs: |--pd0--|--pd4--|---pd8---|
+ RDs: |----rd1----|-----rd2-----|
+
+ Now, consider that userspace decided to split the system with two
+ exclusive cpusets, hence creating two independent root domains, each
+ containing 6 CPUs. The two root domains are denoted rd1 and rd2 in the
+ above figure. Since pd4 intersects with both rd1 and rd2, it will be
+ present in the linked list '->pd' attached to each of them:
+ * rd1->pd: pd0 -> pd4
+ * rd2->pd: pd4 -> pd8
+
+ Please note that the scheduler will create two duplicate list nodes for
+ pd4 (one for each list). However, both just hold a pointer to the same
+ shared data structure of the EM framework.
+
+Since the access to these lists can happen concurrently with hotplug and other
+things, they are protected by RCU, like the rest of topology structures
+manipulated by the scheduler.
+
+EAS also maintains a static key (sched_energy_present) which is enabled when at
+least one root domain meets all conditions for EAS to start. Those conditions
+are summarized in Section 6.
+
+
+4. Energy-Aware task placement
+------------------------------
+
+EAS overrides the CFS task wake-up balancing code. It uses the EM of the
+platform and the PELT signals to choose an energy-efficient target CPU during
+wake-up balance. When EAS is enabled, select_task_rq_fair() calls
+find_energy_efficient_cpu() to do the placement decision. This function looks
+for the CPU with the highest spare capacity (CPU capacity - CPU utilization) in
+each performance domain since it is the one which will allow us to keep the
+frequency the lowest. Then, the function checks if placing the task there could
+save energy compared to leaving it on prev_cpu, i.e. the CPU where the task ran
+in its previous activation.
+
+find_energy_efficient_cpu() uses compute_energy() to estimate what will be the
+energy consumed by the system if the waking task was migrated. compute_energy()
+looks at the current utilization landscape of the CPUs and adjusts it to
+'simulate' the task migration. The EM framework provides the em_pd_energy() API
+which computes the expected energy consumption of each performance domain for
+the given utilization landscape.
+
+An example of energy-optimized task placement decision is detailed below.
+
+Example 2.
+ Let us consider a (fake) platform with 2 independent performance domains
+ composed of two CPUs each. CPU0 and CPU1 are little CPUs; CPU2 and CPU3
+ are big.
+
+ The scheduler must decide where to place a task P whose util_avg = 200
+ and prev_cpu = 0.
+
+ The current utilization landscape of the CPUs is depicted on the graph
+ below. CPUs 0-3 have a util_avg of 400, 100, 600 and 500 respectively
+ Each performance domain has three Operating Performance Points (OPPs).
+ The CPU capacity and power cost associated with each OPP is listed in
+ the Energy Model table. The util_avg of P is shown on the figures
+ below as 'PP'.

+ CPU0 CPU1 CPU2 CPU3
+
+
+ From these calculations, the Case 1 has the lowest total energy. So CPU 1
+ is be the best candidate from an energy-efficiency standpoint.
+
+Big CPUs are generally more power hungry than the little ones and are thus used
+mainly when a task doesn't fit the littles. However, little CPUs aren't always
+necessarily more energy-efficient than big CPUs. For some systems, the high OPPs
+of the little CPUs can be less energy-efficient than the lowest OPPs of the
+bigs, for example. So, if the little CPUs happen to have enough utilization at
+a specific point in time, a small task waking up at that moment could be better
+of executing on the big side in order to save energy, even though it would fit
+on the little side.
+
+And even in the case where all OPPs of the big CPUs are less energy-efficient
+than those of the little, using the big CPUs for a small task might still, under
+specific conditions, save energy. Indeed, placing a task on a little CPU can
+result in raising the OPP of the entire performance domain, and that will
+increase the cost of the tasks already running there. If the waking task is
+placed on a big CPU, its own execution cost might be higher than if it was
+running on a little, but it won't impact the other tasks of the little CPUs
+which will keep running at a lower OPP. So, when considering the total energy
+consumed by CPUs, the extra cost of running that one task on a big core can be
+smaller than the cost of raising the OPP on the little CPUs for all the other
+tasks.
+
+The examples above would be nearly impossible to get right in a generic way, and
+for all platforms, without knowing the cost of running at different OPPs on all
+CPUs of the system. Thanks to its EM-based design, EAS should cope with them
+correctly without too many troubles. However, in order to ensure a minimal
+impact on throughput for high-utilization scenarios, EAS also implements another
+mechanism called 'over-utilization'.
+
+
+5. Over-utilization
+-------------------
+
+From a general standpoint, the use-cases where EAS can help the most are those
+involving a light/medium CPU utilization. Whenever long CPU-bound tasks are
+being run, they will require all of the available CPU capacity, and there isn't
+much that can be done by the scheduler to save energy without severly harming
+throughput. In order to avoid hurting performance with EAS, CPUs are flagged as
+'over-utilized' as soon as they are used at more than 80% of their compute
+capacity. As long as no CPUs are over-utilized in a root domain, load balancing
+is disabled and EAS overridess the wake-up balancing code. EAS is likely to load
+the most energy efficient CPUs of the system more than the others if that can be
+done without harming throughput. So, the load-balancer is disabled to prevent
+it from breaking the energy-efficient task placement found by EAS. It is safe to
+do so when the system isn't overutilized since being below the 80% tipping point
+implies that:
+
+ a. there is some idle time on all CPUs, so the utilization signals used by
+ EAS are likely to accurately represent the 'size' of the various tasks
+ in the system;
+ b. all tasks should already be provided with enough CPU capacity,
+ regardless of their nice values;
+ c. since there is spare capacity all tasks must be blocking/sleeping
+ regularly and balancing at wake-up is sufficient.
+
+As soon as one CPU goes above the 80% tipping point, at least one of the three
+assumptions above becomes incorrect. In this scenario, the 'overutilized' flag
+is raised for the entire root domain, EAS is disabled, and the load-balancer is
+re-enabled. By doing so, the scheduler falls back onto load-based algorithms for
+wake-up and load balance under CPU-bound conditions. This provides a better
+respect of the nice values of tasks.
+
+Since the notion of overutilization largely relies on detecting whether or not
+there is some idle time in the system, the CPU capacity 'stolen' by higher
+(than CFS) scheduling classes (as well as IRQ) must be taken into account. As
+such, the detection of overutilization accounts for the capacity used not only
+by CFS tasks, but also by the other scheduling classes and IRQ.
+
+
+6. Dependencies and requirements for EAS
+----------------------------------------
+
+Energy Aware Scheduling depends on the CPUs of the system having specific
+hardware properties and on other features of the kernel being enabled. This
+section lists these dependencies and provides hints as to how they can be met.
+
+
+ 6.1 - Asymmetric CPU topology
+
+As mentioned in the introduction, EAS is only supported on platforms with
+asymmetric CPU topologies for now. This requirement is checked at run-time by
+looking for the presence of the SD_ASYM_CPUCAPACITY flag when the scheduling
+domains are built.
+
+The flag is set/cleared automatically by the scheduler topology code whenever
+there are CPUs with different capacities in a root domain. The capacities of
+CPUs are provided by arch-specific code through the arch_scale_cpu_capacity()
+callback. As an example, arm and arm64 share an implementation of this callback
+which uses a combination of CPUFreq data and device-tree bindings to compute the
+capacity of CPUs (see drivers/base/arch_topology.c for more details).
+
+So, in order to use EAS on your platform your architecture must implement the
+arch_scale_cpu_capacity() callback, and some of the CPUs must have a lower
+capacity than others.
+
+Please note that EAS is not fundamentally incompatible with SMP, but no
+significant savings on SMP platforms have been observed yet. This restriction
+could be amended in the future if proven otherwise.
+
+
+ 6.2 - Energy Model presence
+
+EAS uses the EM of a platform to estimate the impact of scheduling decisions on
+energy. So, your platform must provide power cost tables to the EM framework in
+order to make EAS start. To do so, please refer to documentation of the
+independent EM framework in Documentation/power/energy-model.txt.
+
+Please also note that the scheduling domains need to be re-built after the
+EM has been registered in order to start EAS.
+
+
+ 6.3 - Energy Model complexity
+
+The task wake-up path is very latency-sensitive. When the EM of a platform is
+too complex (too many CPUs, too many performance domains, too many performance
+states, ...), the cost of using it in the wake-up path can become prohibitive.
+The energy-aware wake-up algorithm has a complexity of:
+
+ C = Nd * (Nc + Ns)
+
+with: Nd the number of performance domains; Nc the number of CPUs; and Ns the
+total number of OPPs (ex: for two perf. domains with 4 OPPs each, Ns = 8).
+
+A complexity check is performed at the root domain level, when scheduling
+domains are built. EAS will not start on a root domain if its C happens to be
+higher than the completely arbitrary EM_MAX_COMPLEXITY threshold (2048 at the
+time of writing).
+
+If you really want to use EAS but the complexity of your platform's Energy
+Model is too high to be used with a single root domain, you're left with only
+two possible options:
+
+ 1. split your system into separate, smaller, root domains using exclusive
+ cpusets and enable EAS locally on each of them. This option has the
+ benefit to work out of the box but the drawback of preventing load
+ balance between root domains, which can result in an unbalanced system
+ overall;
+ 2. submit patches to reduce the complexity of the EAS wake-up algorithm,
+ hence enabling it to cope with larger EMs in reasonable time.
+
+
+ 6.4 - Schedutil governor
+
+EAS tries to predict at which OPP will the CPUs be running in the close future
+in order to estimate their energy consumption. To do so, it is assumed that OPPs
+of CPUs follow their utilization.
+
+Although it is very difficult to provide hard guarantees regarding the accuracy
+of this assumption in practice (because the hardware might not do what it is
+told to do, for example), schedutil as opposed to other CPUFreq governors at
+least _requests_ frequencies calculated using the utilization signals.
+Consequently, the only sane governor to use together with EAS is schedutil,
+because it is the only one providing some degree of consistency between
+frequency requests and energy predictions.
+
+Using EAS with any other governor than schedutil is not supported.
+
+
+ 6.5 Scale-invariant utilization signals
+
+In order to make accurate prediction across CPUs and for all performance
+states, EAS needs frequency-invariant and CPU-invariant PELT signals. These can
+be obtained using the architecture-defined arch_scale{cpu,freq}_capacity()
+callbacks.
+
+Using EAS on a platform that doesn't implement these two callbacks is not
+supported.
+
+
+ 6.6 Multithreading (SMT)
+
+EAS in its current form is SMT unaware and is not able to leverage
+multithreaded hardware to save energy. EAS considers threads as independent
+CPUs, which can actually be counter-productive for both performance and energy.
+
+EAS on SMT is not supported.

-The OSD Standard
-================
-OSD (Object-Based Storage Device) is a T10 SCSI command set that is designed
-to provide efficient operation of input/output logical units that manage the
-allocation, placement, and accessing of variable-size data-storage containers,
-called objects. Objects are intended to contain operating system and application
-constructs. Each object has associated attributes attached to it, which are
-integral part of the object and provide metadata about the object. The standard
-defines some common obligatory attributes, but user attributes can be added as
-needed.
-
-See: http://www.t10.org/ftp/t10/drafts/osd2/ for the latest draft for OSD 2
-or search the web for "OSD SCSI"
-
-OSD in the Linux Kernel
-=======================
-osd-initiator:
- The main component of OSD in Kernel is the osd-initiator library. Its main
-user is intended to be the pNFS-over-objects layout driver, which uses objects
-as its back-end data storage. Other clients are the other osd parts listed below.
-
-osd-uld:
- This is a SCSI ULD that registers for OSD type devices and provides a testing
-platform, both for the in-kernel initiator as well as connected targets. It
-currently has no useful user-mode API, though it could have if need be.
-
-exofs:
- Is an OSD based Linux file system. It uses the osd-initiator and osd-uld,
-to export a usable file system for users.
-See Documentation/filesystems/exofs.txt for more details
-
-osd target:
- There are no current plans for an OSD target implementation in kernel. For all
-needs, a user-mode target that is based on the scsi tgt target framework is
-available from Ohio Supercomputer Center (OSC) at:
-http://www.open-osd.org/bin/view/Main/OscOsdProject
-There are several other target implementations. See http://open-osd.org for more
-links.

-The OSD-Initiator Library
-=========================
-osd_initiator is a low level implementation of an osd initiator encoder.
-But even though, it should be intuitive and easy to use. Perhaps over time an
-higher lever will form that automates some of the more common recipes.
-
-init/fini:
-- osd_dev_init() associates a scsi_device with an osd_dev structure
- and initializes some global pools. This should be done once per scsi_device
- (OSD LUN). The osd_dev structure is needed for calling osd_start_request().
-
-- osd_dev_fini() cleans up before a osd_dev/scsi_device destruction.
-
-OSD commands encoding, execution, and decoding of results:
-
-struct osd_request's is used to iteratively encode an OSD command and carry
-its state throughout execution. Each request goes through these stages:
-
-a. osd_start_request() allocates the request.
-
-b. Any of the osd_req_* methods is used to encode a request of the specified
- type.
-
-c. osd_req_add_{get,set}_attr_* may be called to add get/set attributes to the
- CDB. "List" or "Page" mode can be used exclusively. The attribute-list API
- can be called multiple times on the same request. However, only one
- attribute-page can be read, as mandated by the OSD standard.
-
-d. osd_finalize_request() computes offsets into the data-in and data-out buffers
- and signs the request using the provided capability key and integrity-
- check parameters.
-
-e. osd_execute_request() may be called to execute the request via the block
- layer and wait for its completion. The request can be executed
- asynchronously by calling the block layer API directly.
-
-f. After execution, osd_req_decode_sense() can be called to decode the request's
- sense information.
-
-g. osd_req_decode_get_attr() may be called to retrieve osd_add_get_attr_list()
- values.
-
-h. osd_end_request() must be called to deallocate the request and any resource
- associated with it. Note that osd_end_request cleans up the request at any
- stage and it must always be called after a successful osd_start_request().
-
-osd_request's structure:
-
-The OSD standard defines a complex structure of IO segments pointed to by
-members in the CDB. Up to 3 segments can be deployed in the IN-Buffer and up to
-4 in the OUT-Buffer. The ASCII illustration below depicts a secure-read with
-associated get+set of attributes-lists. Other combinations very on the same
-basic theme. From no-segments-used up to all-segments-used.

-A block device request can carry bidirectional payload by means of associating
-a bidi_read request with a main write-request. Each in/out request is described
-by a chain of BIOs associated with each request.
-The CDB is of a SCSI VARLEN CDB format, as described by OSD standard.
-The OSD standard also mandates alignment restrictions at start of each segment.
-
-In the code, in struct osd_request, there are two _osd_io_info structures to
-describe the IN/OUT buffers above, two BIOs for the data payload and up to five
-_osd_req_data_segment structures to hold the different segments allocation and
-information.
-
-Important: We have chosen to disregard the assumption that a BIO-chain (and
-the resulting sg-list) describes a linear memory buffer. Meaning only first and
-last scatter chain can be incomplete and all the middle chains are of PAGE_SIZE.
-For us, a scatter-gather-list, as its name implies and as used by the Networking
-layer, is to describe a vector of buffers that will be transferred to/from the
-wire. It works very well with current iSCSI transport. iSCSI is currently the
-only deployed OSD transport. In the future we anticipate SAS and FC attached OSD
-devices as well.

-SCTP LSM Support
-================
-
-For security module support, three SCTP specific hooks have been implemented::
-
- security_sctp_assoc_request()
- security_sctp_bind_connect()
- security_sctp_sk_clone()
-
-Also the following security hook has been utilised::
-
- security_inet_conn_established()
-
-The usage of these hooks are described below with the SELinux implementation
-described in ``Documentation/security/SELinux-sctp.rst``
-
-
-security_sctp_assoc_request()
------------------------------
-Passes the ``@ep`` and ``@chunk->skb`` of the association INIT packet to the
-security module. Returns 0 on success, error on failure.
-::
-
- @ep - pointer to sctp endpoint structure.
- @skb - pointer to skbuff of association packet.
-
-
-security_sctp_bind_connect()
------------------------------
-Passes one or more ipv4/ipv6 addresses to the security module for validation
-based on the ``@optname`` that will result in either a bind or connect
-service as shown in the permission check tables below.
-Returns 0 on success, error on failure.
-::
-
- @sk - Pointer to sock structure.
- @optname - Name of the option to validate.
- @address - One or more ipv4 / ipv6 addresses.
- @addrlen - The total length of address(s). This is calculated on each
- ipv4 or ipv6 address using sizeof(struct sockaddr_in) or
- sizeof(struct sockaddr_in6).
-
- ------------------------------------------------------------------
- | BIND Type Checks |
- | @optname | @address contains |
- |----------------------------|-----------------------------------|
- | SCTP_SOCKOPT_BINDX_ADD | One or more ipv4 / ipv6 addresses |
- | SCTP_PRIMARY_ADDR | Single ipv4 or ipv6 address |
- | SCTP_SET_PEER_PRIMARY_ADDR | Single ipv4 or ipv6 address |

- | CONNECT Type Checks |
- | @optname | @address contains |
- |----------------------------|-----------------------------------|
- | SCTP_SOCKOPT_CONNECTX | One or more ipv4 / ipv6 addresses |
- | SCTP_PARAM_ADD_IP | One or more ipv4 / ipv6 addresses |
- | SCTP_SENDMSG_CONNECT | Single ipv4 or ipv6 address |
- | SCTP_PARAM_SET_PRIMARY | Single ipv4 or ipv6 address |
- ------------------------------------------------------------------
-
-A summary of the ``@optname`` entries is as follows::
-
- SCTP_SOCKOPT_BINDX_ADD - Allows additional bind addresses to be
- associated after (optionally) calling
- bind(3).
- sctp_bindx(3) adds a set of bind
- addresses on a socket.
-
- SCTP_SOCKOPT_CONNECTX - Allows the allocation of multiple
- addresses for reaching a peer
- (multi-homed).
- sctp_connectx(3) initiates a connection
- on an SCTP socket using multiple
- destination addresses.
-
- SCTP_SENDMSG_CONNECT - Initiate a connection that is generated by a
- sendmsg(2) or sctp_sendmsg(3) on a new asociation.
-
- SCTP_PRIMARY_ADDR - Set local primary address.
-
- SCTP_SET_PEER_PRIMARY_ADDR - Request peer sets address as
- association primary.
-
- SCTP_PARAM_ADD_IP - These are used when Dynamic Address
- SCTP_PARAM_SET_PRIMARY - Reconfiguration is enabled as explained below.
-
-
-To support Dynamic Address Reconfiguration the following parameters must be
-enabled on both endpoints (or use the appropriate **setsockopt**\(2))::
-
- /proc/sys/net/sctp/addip_enable
- /proc/sys/net/sctp/addip_noauth_enable
-
-then the following *_PARAM_*'s are sent to the peer in an
-ASCONF chunk when the corresponding ``@optname``'s are present::
-
- @optname ASCONF Parameter
- ---------- ------------------
- SCTP_SOCKOPT_BINDX_ADD -> SCTP_PARAM_ADD_IP
- SCTP_SET_PEER_PRIMARY_ADDR -> SCTP_PARAM_SET_PRIMARY
-
-
-security_sctp_sk_clone()
--------------------------
-Called whenever a new socket is created by **accept**\(2)
-(i.e. a TCP style socket) or when a socket is 'peeled off' e.g userspace
-calls **sctp_peeloff**\(3).
-::
-
- @ep - pointer to current sctp endpoint structure.
- @sk - pointer to current sock structure.
- @sk - pointer to new sock structure.
-
-
-security_inet_conn_established()
----------------------------------
-Called when a COOKIE ACK is received::
-
- @sk - pointer to sock structure.
- @skb - pointer to skbuff of the COOKIE ACK packet.
-

+Security Hooks
+--------------
+
+The `SCTP LSM Support`_ chapter above describes the following SCTP security
+hooks with the SELinux specifics expanded below::
+
+ security_sctp_assoc_request()
+ security_sctp_bind_connect()
+ security_sctp_sk_clone()

+security module. Returns 0 on success, error on failure.
+::
+
+ @ep - pointer to sctp endpoint structure.
+ @skb - pointer to skbuff of association packet.
+
+The security module performs the following operations:
+ IF this is the first association on ``@ep->base.sk``, then set the peer
+ sid to that in ``@skb``. This will ensure there is only one peer sid
+ assigned to ``@ep->base.sk`` that may support multiple associations.
+
+ ELSE validate the ``@ep->base.sk peer_sid`` against the ``@skb peer sid``
+ to determine whether the association should be allowed or denied.
+
+ Set the sctp ``@ep sid`` to socket's sid (from ``ep->base.sk``) with
+ MLS portion taken from ``@skb peer sid``. This will be used by SCTP
+ TCP style sockets and peeled off connections as they cause a new socket
+ to be generated.
+
+ If IP security options are configured (CIPSO/CALIPSO), then the ip
+ options are set on the socket.
+
+
+security_sctp_bind_connect()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Checks permissions required for ipv4/ipv6 addresses based on the ``@optname``
+as follows::
+
+ ------------------------------------------------------------------
+ | BIND Permission Checks |
+ | @optname | @address contains |
+ |----------------------------|-----------------------------------|

+~~~~~~~~~~~~~~~~~~~~~~~~
+Called whenever a new socket is created by **accept**\(2) (i.e. a TCP style
+socket) or when a socket is 'peeled off' e.g userspace calls
+**sctp_peeloff**\(3). ``security_sctp_sk_clone()`` will set the new
+sockets sid and peer sid to that contained in the ``@ep sid`` and
+``@ep peer sid`` respectively.
+::
+
+ @ep - pointer to current sctp endpoint structure.
+ @sk - pointer to current sock structure.
+ @sk - pointer to new sock structure.

+Called when a COOKIE ACK is received where it sets the connection's peer sid
+to that in ``@skb``::
+
+ @sk - pointer to sock structure.
+ @skb - pointer to skbuff of the COOKIE ACK packet.
+
+
+Policy Statements
+-----------------
+The following class and permissions to support SCTP are available within the
+kernel::
+
+ class sctp_socket inherits socket { node_bind }
+
+whenever the following policy capability is enabled::
+
+ policycap extended_socket_class;
+
+SELinux SCTP support adds the ``name_connect`` permission for connecting
+to a specific port type and the ``association`` permission that is explained
+in the section below.
+
+If userspace tools have been updated, SCTP will support the ``portcon``
+statement as shown in the following example::
+
+ portcon sctp 1024-1036 system_u:object_r:sctp_ports_t:s0
+
+
+SCTP Peer Labeling
+------------------
+An SCTP socket will only have one peer label assigned to it. This will be
+assigned during the establishment of the first association. Any further
+associations on this socket will have their packet peer label compared to
+the sockets peer label, and only if they are different will the
+``association`` permission be validated. This is validated by checking the
+socket peer sid against the received packets peer sid to determine whether
+the association should be allowed or denied.
+
+NOTES:
+ 1) If peer labeling is not enabled, then the peer context will always be
+ ``SECINITSID_UNLABELED`` (``unlabeled_t`` in Reference Policy).
+
+ 2) As SCTP can support more than one transport address per endpoint
+ (multi-homing) on a single socket, it is possible to configure policy
+ and NetLabel to provide different peer labels for each of these. As the
+ socket peer label is determined by the first associations transport
+ address, it is recommended that all peer labels are consistent.
+
+ 3) **getpeercon**\(3) may be used by userspace to retrieve the sockets peer
+ context.
+
+ 4) While not SCTP specific, be aware when using NetLabel that if a label
+ is assigned to a specific interface, and that interface 'goes down',
+ then the NetLabel service will remove the entry. Therefore ensure that
+ the network startup scripts call **netlabelctl**\(8) to set the required
+ label (see **netlabel-config**\(8) helper script for details).
+
+ 5) The NetLabel SCTP peer labeling rules apply as discussed in the following
+ set of posts tagged "netlabel" at: http://www.paul-moore.com/blog/t.
+
+ 6) CIPSO is only supported for IPv4 addressing: ``socket(AF_INET, ...)``
+ CALIPSO is only supported for IPv6 addressing: ``socket(AF_INET6, ...)``
+
+ Note the following when testing CIPSO/CALIPSO:
+ a) CIPSO will send an ICMP packet if an SCTP packet cannot be
+ delivered because of an invalid label.
+ b) CALIPSO does not send an ICMP packet, just silently discards it.
+
+ 7) IPSEC is not supported as RFC 3554 - sctp/ipsec support has not been
+ implemented in userspace (**racoon**\(8) or **ipsec_pluto**\(8)),
+ although the kernel supports SCTP/IPSEC.

+practice, not every handler.action combination is currently supported;
+if a given handler.action combination isn't supported, the hist
+trigger will fail with -EINVAL;
+
+The default 'handler.action' if none is explicity specified is as it
+always has been, to simply update the set of values associated with an
+entry. Some applications, however, may want to perform additional
+actions at that point, such as generate another event, or compare and
+save a maximum.
+
+The supported handlers and actions are listed below, and each is
+described in more detail in the following paragraphs, in the context
+of descriptions of some common and useful handler.action combinations.
+
+The available handlers are:
+
+ - onmatch(matching.event) - invoke action on any addition or update
+ - onmax(var) - invoke action if var exceeds current max
+ - onchange(var) - invoke action if var changes
+
+The available actions are:
+
+ - trace(<synthetic_event_name>,param list) - generate synthetic event
+ - save(field,...) - save current event fields
+ - snapshot() - snapshot the trace buffer
+
+The following commonly-used handler.action pairs are available:
+
+ - onmatch(matching.event).trace(<synthetic_event_name>,param list)
+
+ The 'onmatch(matching.event).trace(<synthetic_event_name>,param
+ list)' hist trigger action is invoked whenever an event matches
+ and the histogram entry would be added or updated. It causes the
+ named synthetic event to be generated with the values given in the
'param list'. The result is the generation of a synthetic event
that consists of the values contained in those variables at the
- time the invoking event was hit.
-
- The 'param list' consists of one or more parameters which may be
- either variables or fields defined on either the 'matching.event'
- or the target event. The variables or fields specified in the
- param list may be either fully-qualified or unqualified. If a
- variable is specified as unqualified, it must be unique between
- the two events. A field name used as a param can be unqualified
- if it refers to the target event, but must be fully qualified if
- it refers to the matching event. A fully-qualified name is of the

+ time the invoking event was hit. For example, if the synthetic
+ event name is 'wakeup_latency', a wakeup_latency event is
+ generated using onmatch(event).trace(wakeup_latency,arg1,arg2).
+
+ There is also an equivalent alternative form available for
+ generating synthetic events. In this form, the synthetic event
+ name is used as if it were a function name. For example, using
+ the 'wakeup_latency' synthetic event name again, the
+ wakeup_latency event would be generated by invoking it as if it
+ were a function call, with the event field values passed in as
+ arguments: onmatch(event).wakeup_latency(arg1,arg2). The syntax
+ for this form is:

+ The 'onmax(var).snapshot()' hist trigger action is invoked

+ exceeds the current maximum contained in that variable.
+
+ The end result is that a global snapshot of the trace buffer will
+ be saved in the tracing/snapshot file if 'var' exceeds the current
+ maximum for any hist trigger entry.
+
+ Note that in this case the maximum is a global maximum for the
+ current trace instance, which is the maximum across all buckets of
+ the histogram. The key of the specific trace event that caused
+ the global maximum and the global maximum itself are displayed,
+ along with a message stating that a snapshot has been taken and
+ where to find it. The user can use the key information displayed
+ to locate the corresponding bucket in the histogram for even more
+ detail.
+
+ As an example the below defines a couple of hist triggers, one for
+ sched_waking and another for sched_switch, keyed on pid. Whenever
+ a sched_waking event occurs, the timestamp is saved in the entry
+ corresponding to the current pid, and when the scheduler switches
+ back to that pid, the timestamp difference is calculated. If the
+ resulting latency, stored in wakeup_lat, exceeds the current

+ - onchange(var).save(field,.. .)
+
+ The 'onchange(var).save(field,...)' hist trigger action is invoked
+ whenever the value of 'var' associated with a histogram entry
+ changes.
+
+ The end result is that the trace event fields specified as the
+ onchange.save() params will be saved if 'var' changes for that
+ hist trigger entry. This allows context from the event that
+ changed the value to be saved for later reference. When the
+ histogram is displayed, additional fields displaying the saved
+ values will be printed.
+
+ - onchange(var).snapshot()
+
+ The 'onchange(var).snapshot()' hist trigger action is invoked
+ whenever the value of 'var' associated with a histogram entry
+ changes.
+
+ The end result is that a global snapshot of the trace buffer will
+ be saved in the tracing/snapshot file if 'var' changes for any
+ hist trigger entry.
+
+ Note that in this case the changed value is a global variable
+ associated withe current trace instance. The key of the specific
+ trace event that caused the value to change and the global value
+ itself are displayed, along with a message stating that a snapshot
+ has been taken and where to find it. The user can use the key
+ information displayed to locate the corresponding bucket in the
+ histogram for even more detail.
+
+ As an example the below defines a hist trigger on the tcp_probe
+ event, keyed on dport. Whenever a tcp_probe event occurs, the
+ cwnd field is checked against the current value stored in the
+ $cwnd variable. If the value has changed, a snapshot is taken.
+ As part of the setup, all the scheduler and tcp events are also
+ enabled, which are the events that will show up in the snapshot
+ when it is taken at some point:
+
+ # echo 1 > /sys/kernel/debug/tracing/events/sched/enable
+ # echo 1 > /sys/kernel/debug/tracing/events/tcp/enable
+
+ # echo 'hist:keys=dport:cwnd=snd_cwnd: \
+ onchange($cwnd).save(snd_wnd,srtt,rcv_wnd): \
+ onchange($cwnd).snapshot()' >> \
+ /sys/kernel/debug/tracing/events/tcp/tcp_probe/trigger
+
+ When the histogram is displayed, for each bucket the tracked value
+ and the saved values corresponding to that value are displayed
+ following the rest of the fields.
+
+ If a snaphot was taken, there is also a message indicating that,
+ along with the value and event that triggered the snapshot:
+
+ # cat /sys/kernel/debug/tracing/events/tcp/tcp_probe/hist
+ { dport: 1521 } hitcount: 8
+ changed: 10 snd_wnd: 35456 srtt: 154262 rcv_wnd: 42112
+
+ { dport: 80 } hitcount: 23
+ changed: 10 snd_wnd: 28960 srtt: 19604 rcv_wnd: 29312
+
+ { dport: 9001 } hitcount: 172
+ changed: 10 snd_wnd: 48384 srtt: 260444 rcv_wnd: 55168
+
+ { dport: 443 } hitcount: 211
+ changed: 10 snd_wnd: 26960 srtt: 17379 rcv_wnd: 28800
+
+ Snapshot taken (see tracing/snapshot). Details:
+ triggering value { onchange($cwnd) }: 10
+ triggered by event with key: { dport: 80 }
+
+ Totals:
+ Hits: 414
+ Entries: 4
+ Dropped: 0
+
+ In the above case, the event that triggered the snapshot has the
+ key with dport == 80. If you look at the bucket that has 80 as
+ the key, you'll find the additional values save()'d along with the
+ changed value for that bucket, which should be the same as the
+ global changed value (since that was the same value that triggered
+ the global snapshot).
+
+ And finally, looking at the snapshot data should show at or near
+ the end the event that triggered the snapshot:

+
+Riepilogo generale
+------------------
+
+Il resto di questa sezione riguarda il processo di sviluppo del kernel e
+quella sorta di frustrazione che gli sviluppatori e i loro datori di lavoro
+potrebbero dover affrontare. Ci sono molte ragioni per le quali del codice
+per il kernel debba essere incorporato nel kernel ufficiale, fra le quali:
+disponibilità immediata agli utilizzatori, supporto della comunità in
+differenti modalità, e la capacità di influenzare la direzione dello sviluppo
+del kernel.
+Il codice che contribuisce al kernel Linux deve essere reso disponibile sotto
+una licenza GPL-compatibile.
+
+La sezione :ref:`it_development_process` introduce il processo di sviluppo,
+il ciclo di rilascio del kernel, ed i meccanismi della finestra
+d'incorporazione. Il capitolo copre le varie fasi di una modifica: sviluppo,
+revisione e ciclo d'incorporazione. Ci sono alcuni dibattiti su strumenti e
+liste di discussione. Gli sviluppatori che sono in attesa di poter sviluppare
+qualcosa per il kernel sono invitati ad individuare e sistemare bachi come
+esercizio iniziale.
+
+La sezione :ref:`it_development_early_stage` copre i primi stadi della
+pianificazione di un progetto di sviluppo, con particolare enfasi sul
+coinvolgimento della comunità, il prima possibile.
+
+La sezione :ref:`it_development_coding` riguarda il processo di scrittura
+del codice. Qui, sono esposte le diverse insidie che sono state già affrontate
+da altri sviluppatori. Il capitolo copre anche alcuni dei requisiti per le
+modifiche, ed esiste un'introduzione ad alcuni strumenti che possono aiutarvi
+nell'assicurarvi che le modifiche per il kernel siano corrette.
+
+La sezione :ref:`it_development_posting` parla del processo di pubblicazione
+delle modifiche per la revisione. Per essere prese in considerazione dalla
+comunità di sviluppo, le modifiche devono essere propriamente formattate ed
+esposte, e devono essere inviate nel posto giusto. Seguire i consigli presenti
+in questa sezione dovrebbe essere d'aiuto nell'assicurare la migliore
+accoglienza possibile del vostro lavoro.
+
+La sezione :ref:`it_development_followthrough` copre ciò che accade dopo
+la pubblicazione delle modifiche; a questo punto il lavoro è lontano
+dall'essere concluso. Lavorare con i revisori è una parte cruciale del
+processo di sviluppo; questa sezione offre una serie di consigli su come
+evitare problemi in questa importante fase. Gli sviluppatori sono diffidenti
+nell'affermare che il lavoro è concluso quando una modifica è incorporata nei
+sorgenti principali.
+
+La sezione :ref:`it_development_advancedtopics` introduce un paio di argomenti
+"avanzati": gestire le modifiche con git e controllare le modifiche pubblicate
+da altri.
+
+La sezione :ref:`it_development_conclusion` chiude il documento con dei
+riferimenti ad altre fonti che forniscono ulteriori informazioni sullo sviluppo
+del kernel.
+
+Di cosa parla questo documento
+------------------------------
+
+Il kernel Linux, ha oltre 8 milioni di linee di codice e ben oltre 1000
+contributori ad ogni rilascio; è uno dei più vasti e più attivi software
+liberi progettati mai esistiti. Sin dal sul modesto inizio nel 1991,
+questo kernel si è evoluto nel miglior componente per sistemi operativi
+che fanno funzionare piccoli riproduttori musicali, PC, grandi super computer
+e tutte le altre tipologie di sistemi fra questi estremi. È una soluzione
+robusta, efficiente ed adattabile a praticamente qualsiasi situazione.
+
+Con la crescita di Linux è arrivato anche un aumento di sviluppatori
+(ed aziende) desiderosi di partecipare a questo sviluppo. I produttori di
+hardware vogliono assicurarsi che il loro prodotti siano supportati da Linux,
+rendendo questi prodotti attrattivi agli utenti Linux. I produttori di
+sistemi integrati, che usano Linux come componente di un prodotto integrato,
+vogliono che Linux sia capace ed adeguato agli obiettivi ed il più possibile
+alla mano. Fornitori ed altri produttori di software che basano i propri
+prodotti su Linux hanno un chiaro interesse verso capacità, prestazioni ed
+affidabilità del kernel Linux. E gli utenti finali, anche, spesso vorrebbero
+cambiare Linux per renderlo più aderente alle proprie necessità.
+
+Una delle caratteristiche più coinvolgenti di Linux è quella dell'accessibilità
+per gli sviluppatori; chiunque con le capacità richieste può migliorare
+Linux ed influenzarne la direzione di sviluppo. Prodotti non open-source non
+possono offrire questo tipo di apertura, che è una caratteristica del software
+libero. Ma, anzi, il kernel è persino più aperto rispetto a molti altri
+progetti di software libero. Un classico ciclo di sviluppo trimestrale può
+coinvolgere 1000 sviluppatori che lavorano per più di 100 differenti aziende
+(o per nessuna azienda).
+
+Lavorare con la comunità di sviluppo del kernel non è particolarmente
+difficile. Ma, ciononostante, diversi potenziali contributori hanno trovato
+delle difficoltà quando hanno cercato di lavorare sul kernel. La comunità del
+kernel utilizza un proprio modo di operare che gli permette di funzionare
+agevolmente (e genera un prodotto di alta qualità) in un ambiente dove migliaia
+di stringhe di codice sono modificate ogni giorni. Quindi non deve sorprendere
+che il processo di sviluppo del kernel differisca notevolmente dai metodi di
+sviluppo privati.
+
+Il processo di sviluppo del Kernel può, dall'altro lato, risultare
+intimidatorio e strano ai nuovi sviluppatori, ma ha dietro di se buone ragioni
+e solide esperienze. Uno sviluppatore che non comprende i modi della comunità
+del kernel (o, peggio, che cerchi di aggirarli o violarli) avrà un'esperienza
+deludente nel proprio bagaglio. La comunità di sviluppo, sebbene sia utile
+a coloro che cercano di imparare, ha poco tempo da dedicare a coloro che non
+ascoltano o coloro che non sono interessati al processo di sviluppo.
+
+Si spera che coloro che leggono questo documento saranno in grado di evitare
+queste esperienze spiacevoli. C'è molto materiale qui, ma lo sforzo della
+lettura sarà ripagato in breve tempo. La comunità di sviluppo ha sempre
+bisogno di sviluppatori che vogliano aiutare a rendere il kernel migliore;
+il testo seguente potrebbe esservi d'aiuto - o essere d'aiuto ai vostri
+collaboratori- per entrare a far parte della nostra comunità.

+
+L'importanza d'avere il codice nei sorgenti principali
+------------------------------------------------------
+
+Alcune aziende e sviluppatori ogni tanto si domandano perché dovrebbero
+preoccuparsi di apprendere come lavorare con la comunità del kernel e di
+inserire il loro codice nel ramo di sviluppo principale (per ramo principale
+s'intende quello mantenuto da Linus Torvalds e usato come base dai
+distributori Linux). Nel breve termine, contribuire al codice può sembrare
+un costo inutile; può sembra più facile tenere separato il proprio codice e
+supportare direttamente i suoi utilizzatori. La verità è che il tenere il
+codice separato ("fuori dai sorgenti", *"out-of-tree"*) è un falso risparmio.
+
+Per dimostrare i costi di un codice "fuori dai sorgenti", eccovi
+alcuni aspetti rilevanti del processo di sviluppo kernel; la maggior parte
+di essi saranno approfonditi dettagliatamente più avanti in questo documento.
+Considerate:
+
+- Il codice che è stato inserito nel ramo principale del kernel è disponibile
+ a tutti gli utilizzatori Linux. Sarà automaticamente presente in tutte le
+ distribuzioni che lo consentono. Non c'è bisogno di: driver per dischi,
+ scaricare file, o della scocciatura del dover supportare diverse versioni di
+ diverse distribuzioni; funziona già tutto, per gli sviluppatori e per gli
+ utilizzatori. L'inserimento nel ramo principale risolve un gran numero di
+ problemi di distribuzione e di supporto.
+
+- Nonostante gli sviluppatori kernel si sforzino di tenere stabile
+ l'interfaccia dello spazio utente, quella interna al kernel è in continuo
+ cambiamento. La mancanza di un'interfaccia interna è deliberatamente una
+ decisione di progettazione; ciò permette che i miglioramenti fondamentali
+ vengano fatti in un qualsiasi momento e che risultino fatti con un codice di
+ alta qualità. Ma una delle conseguenze di questa politica è che qualsiasi
+ codice "fuori dai sorgenti" richiede costante manutenzione per renderlo
+ funzionante coi kernel più recenti. Tenere un codice "fuori dai sorgenti"
+ richiede una mole di lavoro significativa solo per farlo funzionare.
+
+ Invece, il codice che si trova nel ramo principale non necessita di questo
+ tipo di lavoro poiché ad ogni sviluppatore che faccia una modifica alle
+ interfacce viene richiesto di sistemare anche il codice che utilizza
+ quell'interfaccia. Quindi, il codice che è stato inserito nel ramo principale
+ ha dei costi di mantenimento significativamente più bassi.
+
+- Oltre a ciò, spesso il codice che è all'interno del kernel sarà migliorato da
+ altri sviluppatori. Dare pieni poteri alla vostra comunità di utenti e ai
+ clienti può portare a sorprendenti risultati che migliorano i vostri
+ prodotti.
+
+- Il codice kernel è soggetto a revisioni, sia prima che dopo l'inserimento
+ nel ramo principale. Non importa quanto forti fossero le abilità dello
+ sviluppatore originale, il processo di revisione troverà il modo di migliore
+ il codice. Spesso la revisione trova bachi importanti e problemi di
+ sicurezza. Questo è particolarmente vero per il codice che è stato
+ sviluppato in un ambiente chiuso; tale codice ottiene un forte beneficio
+ dalle revisioni provenienti da sviluppatori esteri. Il codice
+ "fuori dai sorgenti", invece, è un codice di bassa qualità.
+
+- La partecipazione al processo di sviluppo costituisce la vostra via per
+ influenzare la direzione di sviluppo del kernel. Gli utilizzatori che
+ "reclamano da bordo campo" sono ascoltati, ma gli sviluppatori attivi
+ hanno una voce più forte - e la capacità di implementare modifiche che
+ renderanno il kernel più funzionale alle loro necessità.
+
+- Quando il codice è gestito separatamente, esiste sempre la possibilità che
+ terze parti contribuiscano con una differente implementazione che fornisce
+ le stesse funzionalità. Se dovesse accadere, l'inserimento del codice
+ diventerà molto più difficile - fino all'impossibilità. Poi, dovrete far
+ fronte a delle alternative poco piacevoli, come: (1) mantenere un elemento
+ non standard "fuori dai sorgenti" per un tempo indefinito, o (2) abbandonare
+ il codice e far migrare i vostri utenti alla versione "nei sorgenti".
+
+- Contribuire al codice è l'azione fondamentale che fa funzionare tutto il
+ processo. Contribuendo attraverso il vostro codice potete aggiungere nuove
+ funzioni al kernel e fornire competenze ed esempi che saranno utili ad
+ altri sviluppatori. Se avete sviluppato del codice Linux (o state pensando
+ di farlo), avete chiaramente interesse nel far proseguire il successo di
+ questa piattaforma. Contribuire al codice è une delle migliori vie per
+ aiutarne il successo.
+
+Il ragionamento sopra citato si applica ad ogni codice "fuori dai sorgenti"
+dal kernel, incluso il codice proprietario distribuito solamente in formato
+binario. Ci sono, comunque, dei fattori aggiuntivi che dovrebbero essere
+tenuti in conto prima di prendere in considerazione qualsiasi tipo di
+distribuzione binaria di codice kernel. Questo include che:
+
+- Le questioni legali legate alla distribuzione di moduli kernel proprietari
+ sono molto nebbiose; parecchi detentori di copyright sul kernel credono che
+ molti moduli binari siano prodotti derivati del kernel e che, come risultato,
+ la loro diffusione sia una violazione della licenza generale di GNU (della
+ quale si parlerà più avanti). L'autore qui non è un avvocato, e
+ niente in questo documento può essere considerato come un consiglio legale.
+ Il vero stato legale dei moduli proprietari può essere determinato
+ esclusivamente da un giudice. Ma l'incertezza che perseguita quei moduli
+ è lì comunque.
+
+- I moduli binari aumentano di molto la difficoltà di fare debugging del
+ kernel, al punto che la maggior parte degli sviluppatori del kernel non
+ vorranno nemmeno tentare. Quindi la diffusione di moduli esclusivamente
+ binari renderà difficile ai vostri utilizzatori trovare un supporto dalla
+ comunità.
+
+- Il supporto è anche difficile per i distributori di moduli binari che devono
+ fornire una versione del modulo per ogni distribuzione e per ogni versione
+ del kernel che vogliono supportate. Per fornire una copertura ragionevole e
+ comprensiva, può essere richiesto di produrre dozzine di singoli moduli.
+ E inoltre i vostri utilizzatori dovranno aggiornare il vostro modulo
+ separatamente ogni volta che aggiornano il loro kernel.
+
+- Tutto ciò che è stato detto prima riguardo alla revisione del codice si
+ applica doppiamente al codice proprietario. Dato che questo codice non è
+ del tutto disponibile, non può essere revisionato dalla comunità e avrà,
+ senza dubbio, seri problemi.
+
+I produttori di sistemi integrati, in particolare, potrebbero esser tentati
+dall'evitare molto di ciò che è stato detto in questa sezione, credendo che
+stiano distribuendo un prodotto finito che utilizza una versione del kernel
+immutabile e che non richiede un ulteriore sviluppo dopo il rilascio. Questa
+idea non comprende il valore di una vasta revisione del codice e il valore
+del permettere ai propri utenti di aggiungere funzionalità al vostro prodotto.
+Ma anche questi prodotti, hanno una vita commerciale limitata, dopo la quale
+deve essere rilasciata una nuova versione. A quel punto, i produttori il cui
+codice è nel ramo principale di sviluppo avranno un codice ben mantenuto e
+saranno in una posizione migliore per ottenere velocemente un nuovo prodotto
+pronto per essere distribuito.
+
+
+Licenza
+-------
+
+IL codice Linux utilizza diverse licenze, ma il codice completo deve essere
+compatibile con la seconda versione della licenza GNU General Public License
+(GPLv2), che è la licenza che copre la distribuzione del kernel.
+Nella pratica, ciò significa che tutti i contributi al codice sono coperti
+anche'essi dalla GPLv2 (con, opzionalmente, una dicitura che permette la
+possibilità di distribuirlo con licenze più recenti di GPL) o dalla licenza
+three-clause BSD. Qualsiasi contributo che non è coperto da una licenza
+compatibile non verrà accettata nel kernel.
+
+Per il codice sottomesso al kernel non è necessario (o richiesto) la
+concessione del Copyright. Tutto il codice inserito nel ramo principale del
+kernel conserva la sua proprietà originale; ne risulta che ora il kernel abbia
+migliaia di proprietari.
+
+Una conseguenza di questa organizzazione della proprietà è che qualsiasi
+tentativo di modifica della licenza del kernel è destinata ad un quasi sicuro
+fallimento. Esistono alcuni scenari pratici nei quali il consenso di tutti
+i detentori di copyright può essere ottenuto (o il loro codice verrà rimosso
+dal kernel). Quindi, in sostanza, non esiste la possibilità che si giunga ad
+una versione 3 della licenza GPL nel prossimo futuro.
+
+È imperativo che tutto il codice che contribuisce al kernel sia legittimamente
+software libero. Per questa ragione, un codice proveniente da un contributore
+anonimo (o sotto pseudonimo) non verrà accettato. È richiesto a tutti i
+contributori di firmare il proprio codice, attestando così che quest'ultimo
+può essere distribuito insieme al kernel sotto la licenza GPL. Il codice che
+non è stato licenziato come software libero dal proprio creatore, o che
+potrebbe creare problemi di copyright per il kernel (come il codice derivante
+da processi di ingegneria inversa senza le opportune tutele), non può essere
+diffuso.
+
+Domande relative a questioni legate al copyright sono frequenti nelle liste
+di discussione dedicate allo sviluppo di Linux. Tali quesiti, normalmente,
+non riceveranno alcuna risposta, ma una cosa deve essere tenuta presente:
+le persone che risponderanno a quelle domande non sono avvocati e non possono
+fornire supporti legali. Se avete questioni legali relative ai sorgenti
+del codice Linux, non esiste alternativa che quella di parlare con un
+avvocato esperto nel settore. Fare affidamento sulle risposte ottenute da
+una lista di discussione tecnica è rischioso.

+
+Come funziona il processo di sviluppo
+=====================================
+
+Lo sviluppo del Kernel agli inizi degli anno '90 era abbastanza libero, con
+un numero di utenti e sviluppatori relativamente basso. Con una base
+di milioni di utenti e con 2000 sviluppatori coinvolti nel giro di un anno,
+il kernel da allora ha messo in atto un certo numero di procedure per rendere
+lo sviluppo più agevole. È richiesta una solida conoscenza di come tale
+processo si svolge per poter esserne parte attiva.
+
+Il quadro d'insieme
+-------------------
+
+Gli sviluppatori kernel utilizzano un calendario di rilascio generico, dove
+ogni due o tre mesi viene effettuata un rilascio importante del kernel.
+I rilasci più recenti sono stati:
+
+ ====== =================
+ 4.11 Aprile 30, 2017
+ 4.12 Luglio 2, 2017
+ 4.13 Settembre 3, 2017
+ 4.14 Novembre 12, 2017
+ 4.15 Gennaio 28, 2018
+ 4.16 Aprile 1, 2018
+ ====== =================
+
+Ciascun rilascio 4.x è un importante rilascio del kernel con nuove
+funzionalità, modifiche interne dell'API, e molto altro. Un tipico
+rilascio 4.x contiene quasi 13,000 gruppi di modifiche con ulteriori
+modifiche a parecchie migliaia di linee di codice. La 4.x. è pertanto la
+linea di confine nello sviluppo del kernel Linux; il kernel utilizza un sistema
+di sviluppo continuo che integra costantemente nuove importanti modifiche.
+
+Viene seguita una disciplina abbastanza lineare per l'inclusione delle
+patch di ogni rilascio. All'inizio di ogni ciclo di sviluppo, la
+"finestra di inclusione" viene dichiarata aperta. In quel momento il codice
+ritenuto sufficientemente stabile(e che è accettato dalla comunità di sviluppo)
+viene incluso nel ramo principale del kernel. La maggior parte delle
+patch per un nuovo ciclo di sviluppo (e tutte le più importanti modifiche)
+saranno inserite durante questo periodo, ad un ritmo che si attesta sulle
+1000 modifiche ("patch" o "gruppo di modifiche") al giorno.
+
+(per inciso, vale la pena notare che i cambiamenti integrati durante la
+"finestra di inclusione" non escono dal nulla; questi infatti, sono stati
+raccolti e, verificati in anticipo. Il funzionamento di tale procedimento
+verrà descritto dettagliatamente più avanti).
+
+La finestra di inclusione resta attiva approssimativamente per due settimane.
+Al termine di questo periodo, Linus Torvald dichiarerà che la finestra è
+chiusa e rilascerà il primo degli "rc" del kernel.
+Per il kernel che è destinato ad essere 2.6.40, per esempio, il rilascio
+che emerge al termine della finestra d'inclusione si chiamerà 2.6.40-rc1.
+Questo rilascio indica che il momento di aggiungere nuovi componenti è
+passato, e che è iniziato il periodo di stabilizzazione del prossimo kernel.
+
+Nelle successive sei/dieci settimane, potranno essere sottoposte solo modifiche
+che vanno a risolvere delle problematiche. Occasionalmente potrà essere
+consentita una modifica più consistente, ma tali occasioni sono rare.
+Gli sviluppatori che tenteranno di aggiungere nuovi elementi al di fuori della
+finestra di inclusione, tendenzialmente, riceveranno un accoglienza poco
+amichevole. Come regola generale: se vi perdete la finestra di inclusione per
+un dato componente, la cosa migliore da fare è aspettare il ciclo di sviluppo
+successivo (un'eccezione può essere fatta per i driver per hardware non
+supportati in precedenza; se toccano codice non facente parte di quello
+attuale, che non causino regressioni e che potrebbero essere aggiunti in
+sicurezza in un qualsiasi momento)
+
+Mentre le correzioni si aprono la loro strada all'interno del ramo principale,
+il ritmo delle modifiche rallenta col tempo. Linus rilascia un nuovo
+kernel -rc circa una volta alla settimana; e ne usciranno circa 6 o 9 prima
+che il kernel venga considerato sufficientemente stabile e che il rilascio
+finale 2.6.x venga fatto. A quel punto tutto il processo ricomincerà.
+
+Esempio: ecco com'è andato il ciclo di sviluppo della versione 4.16
+(tutte le date si collocano nel 2018)
+
+
+ ============== =======================================
+ Gennaio 28 4.15 rilascio stabile
+ Febbraio 11 4.16-rc1, finestra di inclusione chiusa
+ Febbraio 18 4.16-rc2
+ Febbraio 25 4.16-rc3
+ Marzo 4 4.16-rc4
+ Marzo 11 4.16-rc5
+ Marzo 18 4.16-rc6
+ Marzo 25 4.16-rc7
+ Aprile 1 4.17 rilascio stabile
+ ============== =======================================
+
+In che modo gli sviluppatori decidono quando chiudere il ciclo di sviluppo e
+creare quindi una rilascio stabile? Un metro valido è il numero di regressioni
+rilevate nel precedente rilascio. Nessun baco è il benvenuto, ma quelli che
+procurano problemi su sistemi che hanno funzionato in passato sono considerati
+particolarmente seri. Per questa ragione, le modifiche che portano ad una
+regressione sono viste sfavorevolmente e verranno quasi sicuramente annullate
+durante il periodo di stabilizzazione.
+
+L'obiettivo degli sviluppatori è quello di aggiustare tutte le regressioni
+conosciute prima che avvenga il rilascio stabile. Nel mondo reale, questo
+tipo di perfezione difficilmente viene raggiunta; esistono troppe variabili
+in un progetto di questa portata. Arriva un punto dove ritardare il rilascio
+finale peggiora la situazione; la quantità di modifiche in attesa della
+prossima finestra di inclusione crescerà enormemente, creando ancor più
+regressioni al giro successivo. Quindi molti kernel 4.x escono con una
+manciata di regressioni delle quali, si spera, nessuna è grave.
+
+Una volta che un rilascio stabile è fatto, il suo costante mantenimento è
+affidato al "squadra stabilità", attualmente composta da Greg Kroah-Hartman.
+Questa squadra rilascia occasionalmente degli aggiornamenti relativi al
+rilascio stabile usando la numerazione 4.x.y. Per essere presa in
+considerazione per un rilascio d'aggiornamento, una modifica deve:
+(1) correggere un baco importante (2) essere già inserita nel ramo principale
+per il prossimo sviluppo del kernel. Solitamente, passato il loro rilascio
+iniziale, i kernel ricevono aggiornamenti per più di un ciclo di sviluppo.
+Quindi, per esempio, la storia del kernel 4.13 appare così:
+
+ ============== ===============================
+ Settembre 3 4.13 rilascio stabile
+ Settembre 13 4.13.1
+ Settembre 20 4.13.2
+ Settembre 27 4.13.3
+ Ottobre 5 4.13.4
+ Ottobre 12 4.13.5
+ ... ...
+ Novembre 24 4.13.16
+ ============== ===============================
+
+La 4.13.16 fu l'aggiornamento finale per la versione 4.13.
+
+Alcuni kernel sono destinati ad essere kernel a "lungo termine"; questi
+riceveranno assistenza per un lungo periodo di tempo. Al momento in cui
+scriviamo, i manutentori dei kernel stabili a lungo termine sono:
+
+ ====== ====================== ==========================================
+ 3.16 Ben Hutchings (kernel stabile molto più a lungo termine)
+ 4.1 Sasha Levin
+ 4.4 Greg Kroah-Hartman (kernel stabile molto più a lungo termine)
+ 4.9 Greg Kroah-Hartman
+ 4.14 Greg Kroah-Hartman
+ ====== ====================== ==========================================
+
+
+Questa selezione di kernel di lungo periodo sono puramente dovuti ai loro
+manutentori, alla loro necessità e al tempo per tenere aggiornate proprio
+quelle versioni. Non ci sono altri kernel a lungo termine in programma per
+alcun rilascio in arrivo.
+
+Il ciclo di vita di una patch
+-----------------------------
+
+Le patch non passano direttamente dalla tastiera dello sviluppatori
+al ramo principale del kernel. Esiste, invece, una procedura disegnata
+per assicurare che ogni patch sia di buona qualità e desiderata nel
+ramo principale. Questo processo avviene velocemente per le correzioni
+meno importanti, o, nel caso di patch ampie e controverse, va avanti per anni.
+Per uno sviluppatore la maggior frustrazione viene dalla mancanza di
+comprensione di questo processo o dai tentativi di aggirarlo.
+
+Nella speranza di ridurre questa frustrazione, questo documento spiegherà
+come una patch viene inserita nel kernel. Ciò che segue è un'introduzione
+che descrive il processo ideale. Approfondimenti verranno invece trattati
+più avanti.
+
+Una patch attraversa, generalmente, le seguenti fasi:
+
+ - Progetto. In questa fase sono stabilite quelli che sono i requisiti
+ della modifica - e come verranno soddisfatti. Il lavoro di progettazione
+ viene spesso svolto senza coinvolgere la comunità, ma è meglio renderlo
+ il più aperto possibile; questo può far risparmiare molto tempo evitando
+ eventuali riprogettazioni successive.
+
+ - Prima revisione. Le patch vengono pubblicate sulle liste di discussione
+ interessate, e gli sviluppatori in quella lista risponderanno coi loro
+ commenti. Se si svolge correttamente, questo procedimento potrebbe far
+ emergere problemi rilevanti in una patch.
+
+ - Revisione più ampia. Quando la patch è quasi pronta per essere inserita
+ nel ramo principale, un manutentore importante del sottosistema dovrebbe
+ accettarla - anche se, questa accettazione non è una garanzia che la
+ patch arriverà nel ramo principale. La patch sarà visibile nei sorgenti
+ del sottosistema in questione e nei sorgenti -next (descritti sotto).
+ Quando il processo va a buon fine, questo passo porta ad una revisione
+ più estesa della patch e alla scoperta di problemi d'integrazione
+ con il lavoro altrui.
+
+- Per favore, tenete da conto che la maggior parte dei manutentori ha
+ anche un lavoro quotidiano, quindi integrare le vostre patch potrebbe
+ non essere la loro priorità più alta. Se una vostra patch riceve
+ dei suggerimenti su dei cambiamenti necessari, dovreste applicare
+ quei cambiamenti o giustificare perché non sono necessari. Se la vostra
+ patch non riceve alcuna critica ma non è stata integrata dal
+ manutentore del driver o sottosistema, allora dovreste continuare con
+ i necessari aggiornamenti per mantenere la patch aggiornata al kernel
+ più recente cosicché questa possa integrarsi senza problemi; continuate
+ ad inviare gli aggiornamenti per essere revisionati e integrati.
+
+ - Inclusione nel ramo principale. Eventualmente, una buona patch verrà
+ inserita all'interno nel repositorio principale, gestito da
+ Linus Torvalds. In questa fase potrebbero emergere nuovi problemi e/o
+ commenti; è importante che lo sviluppatore sia collaborativo e che sistemi
+ ogni questione che possa emergere.
+
+ - Rilascio stabile. Ora, il numero di utilizzatori che sono potenzialmente
+ toccati dalla patch è aumentato, quindi, ancora una volta, potrebbero
+ emergere nuovi problemi.
+
+ - Manutenzione di lungo periodo. Nonostante sia possibile che uno sviluppatore
+ si dimentichi del codice dopo la sua integrazione, questo comportamento
+ lascia una brutta impressione nella comunità di sviluppo. Integrare il
+ codice elimina alcuni degli oneri facenti parte della manutenzione, in
+ particolare, sistemerà le problematiche causate dalle modifiche all'API.
+ Ma lo sviluppatore originario dovrebbe continuare ad assumersi la
+ responsabilità per il codice se quest'ultimo continua ad essere utile
+ nel lungo periodo.
+
+Uno dei più grandi errori fatti dagli sviluppatori kernel (o dai loro datori
+di lavoro) è quello di cercare di ridurre tutta la procedura ad una singola
+"integrazione nel remo principale". Questo approccio inevitabilmente conduce
+a una condizione di frustrazione per tutti coloro che sono coinvolti.
+
+Come le modifiche finiscono nel Kernel
+--------------------------------------
+
+Esiste una sola persona che può inserire le patch nel repositorio principale
+del kernel: Linus Torvalds. Ma, di tutte le 9500 patch che entrarono nella
+versione 2.6.38 del kernel, solo 112 (circa l'1,3%) furono scelte direttamente
+da Linus in persona. Il progetto del kernel è cresciuto fino a raggiungere
+una dimensione tale per cui un singolo sviluppatore non può controllare e
+selezionare indipendentemente ogni modifica senza essere supportato.
+La via scelta dagli sviluppatori per indirizzare tale crescita è stata quella
+di utilizzare un sistema di "sottotenenti" basato sulla fiducia.
+
+Il codice base del kernel è spezzato in una serie si sottosistemi: rete,
+supporto per specifiche architetture, gestione della memoria, video e
+strumenti, etc. Molti sottosistemi hanno un manutentore designato: ovvero uno
+sviluppatore che ha piena responsabilità di tutto il codice presente in quel
+sottosistema. Tali manutentori di sottosistema sono i guardiani
+(in un certo senso) della parte di kernel che gestiscono; sono coloro che
+(solitamente) accetteranno una patch per l'inclusione nel ramo principale
+del kernel.
+
+I manutentori di sottosistema gestiscono ciascuno la propria parte dei sorgenti
+del kernel, utilizzando abitualmente (ma certamente non sempre) git.
+Strumenti come git (e affini come quilt o mercurial) permettono ai manutentori
+di stilare una lista delle patch, includendo informazioni sull'autore ed
+altri metadati. In ogni momento, il manutentore può individuare quale patch
+nel sua repositorio non si trova nel ramo principale.
+
+Quando la "finestra di integrazione" si apre, i manutentori di alto livello
+chiederanno a Linus di "prendere" dai loro repositori le modifiche che hanno
+selezionato per l'inclusione. Se Linus acconsente, il flusso di patch si
+convoglierà nel repositorio di quest ultimo, divenendo così parte del ramo
+principale del kernel. La quantità d'attenzione che Linus presta alle
+singole patch ricevute durante l'operazione di integrazione varia.
+È chiaro che, qualche volta, guardi più attentamente. Ma, come regola
+generale, Linus confida nel fatto che i manutentori di sottosistema non
+selezionino pessime patch.
+
+I manutentori di sottosistemi, a turno, possono "prendere" patch
+provenienti da altri manutentori. Per esempio, i sorgenti per la rete rete
+sono costruiti da modifiche che si sono accumulate inizialmente nei sorgenti
+dedicati ai driver per dispositivi di rete, rete senza fili, ecc. Tale
+catena di repositori può essere più o meno lunga, benché raramente ecceda
+i due o tre collegamenti. Questo processo è conosciuto come
+"la catena della fiducia", perché ogni manutentore all'interno della
+catena si fida di coloro che gestiscono i livelli più bassi.
+
+Chiaramente, in un sistema come questo, l'inserimento delle patch all'interno
+del kernel si basa sul trovare il manutentore giusto. Di norma, inviare
+patch direttamente a Linus non è la via giusta.
+
+
+Sorgenti -next
+--------------
+
+La catena di sottosistemi guida il flusso di patch all'interno del kernel,
+ma solleva anche un interessante quesito: se qualcuno volesse vedere tutte le
+patch pronte per la prossima finestra di integrazione?
+Gli sviluppatori si interesseranno alle patch in sospeso per verificare
+che non ci siano altri conflitti di cui preoccuparsi; una modifica che, per
+esempio, cambia il prototipo di una funzione fondamentale del kernel andrà in
+conflitto con qualsiasi altra modifica che utilizzi la vecchia versione di
+quella funzione. Revisori e tester vogliono invece avere accesso alle
+modifiche nella loro totalità prima che approdino nel ramo principale del
+kernel. Uno potrebbe prendere le patch provenienti da tutti i sottosistemi
+d'interesse, ma questo sarebbe un lavoro enorme e fallace.
+
+La risposta ci viene sotto forma di sorgenti -next, dove i sottosistemi sono
+raccolti per essere testati e controllati. Il più vecchio di questi sorgenti,
+gestito da Andrew Morton, è chiamato "-mm" (memory management, che è l'inizio
+di tutto). L'-mm integra patch proveniente da una lunga lista di sottosistemi;
+e ha, inoltre, alcune patch destinate al supporto del debugging.
+
+Oltre a questo, -mm contiene una raccolta significativa di patch che sono
+state selezionate da Andrew direttamente. Queste patch potrebbero essere
+state inviate in una lista di discussione, o possono essere applicate ad una
+parte del kernel per la quale non esiste un sottosistema dedicato.
+Di conseguenza, -mm opera come una specie di sottosistema "ultima spiaggia";
+se per una patch non esiste una via chiara per entrare nel ramo principale,
+allora è probabile che finirà in -mm. Le patch passate per -mm
+eventualmente finiranno nel sottosistema più appropriato o saranno inviate
+direttamente a Linus. In un tipico ciclo di sviluppo, circa il 5-10% delle
+patch andrà nel ramo principale attraverso -mm.
+
+La patch -mm correnti sono disponibili nella cartella "mmotm" (-mm of
+the moment) all'indirizzo:
+
+ http://www.ozlabs.org/~akpm/mmotm/
+
+È molto probabile che l'uso dei sorgenti MMOTM diventi un'esperienza
+frustrante; ci sono buone probabilità che non compili nemmeno.
+
+I sorgenti principali per il prossimo ciclo d'integrazione delle patch
+è linux-next, gestito da Stephen Rothwell. I sorgenti linux-next sono, per
+definizione, un'istantanea di come dovrà apparire il ramo principale dopo che
+la prossima finestra di inclusione si chiuderà. I linux-next sono annunciati
+sulla lista di discussione linux-kernel e linux-next nel momento in cui
+vengono assemblati; e possono essere scaricate da:
+
+ http://www.kernel.org/pub/linux/kernel/next/
+
+Linux-next è divenuto parte integrante del processo di sviluppo del kernel;
+tutte le patch incorporate durante una finestra di integrazione dovrebbero
+aver trovato la propria strada in linux-next, a volte anche prima dell'apertura
+della finestra di integrazione.
+
+
+Sorgenti in preparazione
+------------------------
+
+Nei sorgenti del kernel esiste la cartella drivers/staging/, dove risiedono
+molte sotto-cartelle per i driver o i filesystem che stanno per essere aggiunti
+al kernel. Questi restano nella cartella drivers/staging fintanto che avranno
+bisogno di maggior lavoro; una volta completato, possono essere spostate
+all'interno del kernel nel posto più appropriato. Questo è il modo di tener
+traccia dei driver che non sono ancora in linea con gli standard di codifica
+o qualità, ma che le persone potrebbero voler usare ugualmente e tracciarne
+lo sviluppo.
+
+Greg Kroah-Hartman attualmente gestisce i sorgenti in preparazione. I driver
+che non sono completamente pronti vengono inviati a lui, e ciascun driver avrà
+la propria sotto-cartella in drivers/staging/. Assieme ai file sorgenti
+dei driver, dovrebbe essere presente nella stessa cartella anche un file TODO.
+Il file TODO elenca il lavoro ancora da fare su questi driver per poter essere
+accettati nel kernel, e indica anche la lista di persone da inserire in copia
+conoscenza per ogni modifica fatta. Le regole attuali richiedono che i
+driver debbano, come minimo, compilare adeguatamente.
+
+La *preparazione* può essere una via relativamente facile per inserire nuovi
+driver all'interno del ramo principale, dove, con un po' di fortuna, saranno
+notati da altri sviluppatori e migliorati velocemente. Entrare nella fase
+di preparazione non è però la fine della storia, infatti, il codice che si
+trova nella cartella staging che non mostra regolari progressi potrebbe
+essere rimosso. Le distribuzioni, inoltre, tendono a dimostrarsi relativamente
+riluttanti nell'attivare driver in preparazione. Quindi lo preparazione è,
+nel migliore dei casi, una tappa sulla strada verso il divenire un driver
+del ramo principale.
+
+
+Strumenti
+---------
+
+Come è possibile notare dal testo sopra, il processo di sviluppo del kernel
+dipende pesantemente dalla capacità di guidare la raccolta di patch in
+diverse direzioni. L'intera cosa non funzionerebbe se non venisse svolta
+con l'uso di strumenti appropriati e potenti. Spiegare l'uso di tali
+strumenti non è lo scopo di questo documento, ma c'è spazio per alcuni
+consigli.
+
+In assoluto, nella comunità del kernel, predomina l'uso di git come sistema
+di gestione dei sorgenti. Git è una delle diverse tipologie di sistemi
+distribuiti di controllo versione che sono stati sviluppati nella comunità
+del software libero. Esso è calibrato per lo sviluppo del kernel, e si
+comporta abbastanza bene quando ha a che fare con repositori grandi e con un
+vasto numero di patch. Git ha inoltre la reputazione di essere difficile
+da imparare e utilizzare, benché stia migliorando. Agli sviluppatori
+del kernel viene richiesta un po' di familiarità con git; anche se non lo
+utilizzano per il proprio lavoro, hanno bisogno di git per tenersi al passo
+con il lavoro degli altri sviluppatori (e con il ramo principale).
+
+Git è ora compreso in quasi tutte le distribuzioni Linux. Esiste una sito che
+potete consultare:
+
+ http://git-scm.com/
+
+Qui troverete i riferimenti alla documentazione e alle guide passo-passo.
+
+Tra gli sviluppatori Kernel che non usano git, la scelta alternativa più
+popolare è quasi sicuramente Mercurial:
+
+ http://www.selenic.com/mercurial/
+
+Mercurial condivide diverse caratteristiche con git, ma fornisce
+un'interfaccia che potrebbe risultare più semplice da utilizzare.
+
+L'altro strumento che vale la pena conoscere è Quilt:
+
+ http://savannah.nongnu.org/projects/quilt/
+
+
+Quilt è un sistema di gestione delle patch, piuttosto che un sistema
+di gestione dei sorgenti. Non mantiene uno storico degli eventi; ma piuttosto
+è orientato verso il tracciamento di uno specifico insieme di modifiche
+rispetto ad un codice in evoluzione. Molti dei più grandi manutentori di
+sottosistema utilizzano quilt per gestire le patch che dovrebbero essere
+integrate. Per la gestione di certe tipologie di sorgenti (-mm, per esempio),
+quilt è il miglior strumento per svolgere il lavoro.
+
+
+Liste di discussione
+--------------------
+
+Una grossa parte del lavoro di sviluppo del Kernel Linux viene svolto tramite
+le liste di discussione. È difficile essere un membro della comunità
+pienamente coinvolto se non si partecipa almeno ad una lista da qualche
+parte. Ma, le liste di discussione di Linux rappresentano un potenziale
+problema per gli sviluppatori, che rischiano di venir sepolti da un mare di
+email, restare incagliati nelle convenzioni in vigore nelle liste Linux,
+o entrambi.
+
+Molte delle liste di discussione del Kernel girano su vger.kernel.org;
+l'elenco principale lo si trova sul sito:
+
+ http://vger.kernel.org/vger-lists.html
+
+Esistono liste gestite altrove; un certo numero di queste sono in
+lists.redhat.com.
+
+La lista di discussione principale per lo sviluppo del kernel è, ovviamente,
+linux-kernel. Questa lista è un luogo ostile dove trovarsi; i volumi possono
+raggiungere i 500 messaggi al giorno, la quantità di "rumore" è elevata,
+la conversazione può essere strettamente tecnica e i partecipanti non sono
+sempre preoccupati di mostrare un alto livello di educazione. Ma non esiste
+altro luogo dove la comunità di sviluppo del kernel si unisce per intero;
+gli sviluppatori che evitano tale lista si perderanno informazioni importanti.
+
+Ci sono alcuni consigli che possono essere utili per sopravvivere a
+linux-kernel:
+
+- Tenete la lista in una cartella separata, piuttosto che inserirla nella
+ casella di posta principale. Così da essere in grado di ignorare il flusso
+ di mail per un certo periodo di tempo.
+
+- Non cercate di seguire ogni conversazione - nessuno lo fa. È importante
+ filtrare solo gli argomenti d'interesse (sebbene va notato che le
+ conversazioni di lungo periodo possono deviare dall'argomento originario
+ senza cambiare il titolo della mail) e le persone che stanno partecipando.
+
+- Non alimentate i troll. Se qualcuno cerca di creare nervosismo, ignoratelo.
+
+- Quando rispondete ad una mail linux-kernel (o ad altre liste) mantenete
+ tutti i Cc:. In assenza di importanti motivazioni (come una richiesta
+ esplicita), non dovreste mai togliere destinatari. Assicuratevi sempre che
+ la persona alla quale state rispondendo sia presente nella lista Cc. Questa
+ usanza fa si che divenga inutile chiedere esplicitamente di essere inseriti
+ in copia nel rispondere al vostro messaggio.
+
+- Cercate nell'archivio della lista (e nella rete nella sua totalità) prima
+ di far domande. Molti sviluppatori possono divenire impazienti con le
+ persone che chiaramente non hanno svolto i propri compiti a casa.
+
+- Evitate il *top-posting* (cioè la pratica di mettere la vostra risposta sopra
+ alla frase alla quale state rispondendo). Ciò renderebbe la vostra risposta
+ difficile da leggere e genera scarsa impressione.
+
+- Chiedete nella lista di discussione corretta. Linux-kernel può essere un
+ punto di incontro generale, ma non è il miglior posto dove trovare
+ sviluppatori da tutti i sottosistemi.
+
+Infine, la ricerca della corretta lista di discussione è uno degli errori più
+comuni per gli sviluppatori principianti. Qualcuno che pone una domanda
+relativa alla rete su linux-kernel riceverà quasi certamente il suggerimento
+di chiedere sulla lista netdev, che è la lista frequentata dagli sviluppatori
+di rete. Ci sono poi altre liste per i sottosistemi SCSI, video4linux, IDE,
+filesystem, etc. Il miglior posto dove cercare una lista di discussione è il
+file MAINTAINERS che si trova nei sorgenti del kernel.
+
+Iniziare con lo sviluppo del Kernel
+-----------------------------------
+
+Sono comuni le domande sul come iniziare con lo sviluppo del kernel - sia da
+singole persone che da aziende. Altrettanto comuni sono i passi falsi che
+rendono l'inizio di tale relazione più difficile di quello che dovrebbe essere.
+
+Le aziende spesso cercano di assumere sviluppatori noti per creare un gruppo
+di sviluppo iniziale. Questo, in effetti, può essere una tecnica efficace.
+Ma risulta anche essere dispendiosa e non va ad accrescere il bacino di
+sviluppatori kernel con esperienza. È possibile anche "portare a casa"
+sviluppatori per accelerare lo sviluppo del kernel, dando comunque
+all'investimento un po' di tempo. Prendersi questo tempo può fornire
+al datore di lavoro un gruppo di sviluppatori che comprendono sia il kernel
+che l'azienda stessa, e che possono supportare la formazione di altre persone.
+Nel medio periodo, questa è spesso uno delle soluzioni più proficue.
+
+I singoli sviluppatori sono spesso, comprensibilmente, una perdita come punto
+di partenza. Iniziare con un grande progetto può rivelarsi intimidatorio;
+spesso all'inizio si vuole solo verificare il terreno con qualcosa di piccolo.
+Questa è una delle motivazioni per le quali molti sviluppatori saltano alla
+creazione di patch che vanno a sistemare errori di battitura o
+problematiche minori legate allo stile del codice. Sfortunatamente, tali
+patch creano un certo livello di rumore che distrae l'intera comunità di
+sviluppo, quindi, sempre di più, esse vengono degradate. I nuovi sviluppatori
+che desiderano presentarsi alla comunità non riceveranno l'accoglienza
+che vorrebbero con questi mezzi.
+
+Andrew Morton da questo consiglio agli aspiranti sviluppatori kernel
+
+::
+
+ Il primo progetto per un neofita del kernel dovrebbe essere
+ sicuramente quello di "assicurarsi che il kernel funzioni alla
+ perfezione sempre e su tutte le macchine sulle quali potete stendere
+ la vostra mano". Solitamente il modo per fare ciò è quello di
+ collaborare con gli altri nel sistemare le cose (questo richiede
+ persistenza!) ma va bene - è parte dello sviluppo kernel.
+
+(http://lwn.net/Articles/283982/).
+
+In assenza di problemi ovvi da risolvere, si consiglia agli sviluppatori
+di consultare, in generale, la lista di regressioni e di bachi aperti.
+Non c'è mai carenza di problematiche bisognose di essere sistemate;
+accollandosi tali questioni gli sviluppatori accumuleranno esperienza con
+la procedura, ed allo stesso tempo, aumenteranno la loro rispettabilità
+all'interno della comunità di sviluppo.

+
+I primi passi della pianificazione
+==================================
+
+Osservando un progetto di sviluppo per il kernel Linux, si potrebbe essere
+tentati dal saltare tutto e iniziare a codificare. Tuttavia, come ogni
+progetto significativo, molta della preparazione per giungere al successo
+viene fatta prima che una sola linea di codice venga scritta. Il tempo speso
+nella pianificazione e la comunicazione può far risparmiare molto
+tempo in futuro.
+
+Specificare il problema
+-----------------------
+
+Come qualsiasi progetto ingegneristico, un miglioramento del kernel di
+successo parte con una chiara descrizione del problema da risolvere.
+In alcuni casi, questo passaggio è facile: ad esempio quando un driver è
+richiesto per un particolare dispositivo. In altri casi invece, si
+tende a confondere il problema reale con le soluzioni proposte e questo
+può portare all'emergere di problemi.
+
+Facciamo un esempio: qualche anno fa, gli sviluppatori che lavoravano con
+linux audio cercarono un modo per far girare le applicazioni senza dropouts
+o altri artefatti dovuti all'eccessivo ritardo nel sistema. La soluzione
+alla quale giunsero fu un modulo del kernel destinato ad agganciarsi al
+framework Linux Security Module (LSM); questo modulo poteva essere
+configurato per dare ad una specifica applicazione accesso allo
+schedulatore *realtime*. Tale modulo fu implementato e inviato nella
+lista di discussione linux-kernel, dove incontrò subito dei problemi.
+
+Per gli sviluppatori audio, questo modulo di sicurezza era sufficiente a
+risolvere il loro problema nell'immediato. Per l'intera comunità kernel,
+invece, era un uso improprio del framework LSM (che non è progettato per
+conferire privilegi a processi che altrimenti non avrebbero potuto ottenerli)
+e un rischio per la stabilità del sistema. Le loro soluzioni di punta nel
+breve periodo, comportavano un accesso alla schedulazione realtime attraverso
+il meccanismo rlimit, e nel lungo periodo un costante lavoro nella riduzione
+dei ritardi.
+
+La comunità audio, comunque, non poteva vedere al di là della singola
+soluzione che avevano implementato; erano riluttanti ad accettare alternative.
+Il conseguente dissenso lasciò in quegli sviluppatori un senso di
+disillusione nei confronti dell'intero processo di sviluppo; uno di loro
+scrisse questo messaggio:
+
+ Ci sono numerosi sviluppatori del kernel Linux davvero bravi, ma
+ rischiano di restare sovrastati da una vasta massa di stolti arroganti.
+ Cercare di comunicare le richieste degli utenti a queste persone è
+ una perdita di tempo. Loro sono troppo "intelligenti" per stare ad
+ ascoltare dei poveri mortali.
+
+ (http://lwn.net/Articles/131776/).
+
+La realtà delle cose fu differente; gli sviluppatori del kernel erano molto
+più preoccupati per la stabilità del sistema, per la manutenzione di lungo
+periodo e cercavano la giusta soluzione alla problematica esistente con uno
+specifico modulo. La morale della storia è quella di concentrarsi sul
+problema - non su di una specifica soluzione- e di discuterne con la comunità
+di sviluppo prima di investire tempo nella scrittura del codice.
+
+Quindi, osservando un progetto di sviluppo del kernel, si dovrebbe
+rispondere a questa lista di domande:
+
+- Qual'è, precisamente, il problema che dev'essere risolto?
+
+- Chi sono gli utenti coinvolti da tal problema? A quale caso dovrebbe
+ essere indirizzata la soluzione?
+
+- In che modo il kernel risulta manchevole nell'indirizzare il problema
+ in questione?
+
+Solo dopo ha senso iniziare a considerare le possibili soluzioni.
+
+Prime discussioni
+-----------------
+
+Quando si pianifica un progetto di sviluppo per il kernel, sarebbe quanto meno
+opportuno discuterne inizialmente con la comunità prima di lanciarsi
+nell'implementazione. Una discussione preliminare può far risparmiare sia
+tempo che problemi in svariati modi:
+
+ - Potrebbe essere che il problema sia già stato risolto nel kernel in
+ una maniera che non avete ancora compreso. Il kernel Linux è grande e ha
+ una serie di funzionalità e capacità che non sono scontate nell'immediato.
+ Non tutte le capacità del kernel sono documentate così bene come ci
+ piacerebbe, ed è facile perdersi qualcosa. Il vostro autore ha assistito
+ alla pubblicazione di un driver intero che duplica un altro driver
+ esistente di cui il nuovo autore era ignaro. Il codice che rinnova
+ ingranaggi già esistenti non è soltanto dispendioso; non verrà nemmeno
+ accettato nel ramo principale del kernel.
+
+ - Potrebbero esserci proposte che non sono considerate accettabili per
+ l'integrazione all'interno del ramo principale. È meglio affrontarle
+ prima di scrivere il codice.
+
+ - È possibile che altri sviluppatori abbiano pensato al problema; potrebbero
+ avere delle idee per soluzioni migliori, e potrebbero voler contribuire
+ alla loro creazione.
+
+Anni di esperienza con la comunità di sviluppo del kernel hanno impartito una
+chiara lezione: il codice per il kernel che è pensato e sviluppato a porte
+chiuse, inevitabilmente, ha problematiche che si rivelano solo quando il
+codice viene rilasciato pubblicamente. Qualche volta tali problemi sono
+importanti e richiedono mesi o anni di sforzi prima che il codice possa
+raggiungere gli standard richiesti della comunità.
+Alcuni esempi possono essere:
+
+ - La rete Devicescape è stata creata e implementata per sistemi
+ mono-processore. Non avrebbe potuto essere inserita nel ramo principale
+ fino a che non avesse supportato anche i sistemi multi-processore.
+ Riadattare i meccanismi di sincronizzazione e simili è un compito difficile;
+ come risultato, l'inserimento di questo codice (ora chiamato mac80211)
+ fu rimandato per più di un anno.
+
+ - Il filesystem Reiser4 include una seria di funzionalità che, secondo
+ l'opinione degli sviluppatori principali del kernel, avrebbero dovuto
+ essere implementate a livello di filesystem virtuale. Comprende
+ anche funzionalità che non sono facilmente implementabili senza esporre
+ il sistema al rischio di uno stallo. La scoperta tardiva di questi
+ problemi - e il diniego a risolverne alcuni - ha avuto come conseguenza
+ il fatto che Raiser4 resta fuori dal ramo principale del kernel.
+
+ - Il modulo di sicurezza AppArmor utilizzava strutture dati del
+ filesystem virtuale interno in modi che sono stati considerati rischiosi e
+ inattendibili. Questi problemi (tra le altre cose) hanno tenuto AppArmor
+ fuori dal ramo principale per anni.
+
+Ciascuno di questi casi è stato un travaglio e ha richiesto del lavoro
+straordinario, cose che avrebbero potuto essere evitate con alcune
+"chiacchierate" preliminari con gli sviluppatori kernel.
+
+Con chi parlare?
+----------------
+
+Quando gli sviluppatori hanno deciso di rendere pubblici i propri progetti, la
+domanda successiva sarà: da dove partiamo? La risposta è quella di trovare
+la giusta lista di discussione e il giusto manutentore. Per le liste di
+discussione, il miglior approccio è quello di cercare la lista più adatta
+nel file MAINTAINERS. Se esiste una lista di discussione di sottosistema,
+è preferibile pubblicare lì piuttosto che sulla lista di discussione generale
+del kernel Linux; avrete maggiori probabilità di trovare sviluppatori con
+esperienza sul tema, e l'ambiente che troverete potrebbe essere più
+incoraggiante.
+
+Trovare manutentori può rivelarsi un po' difficoltoso. Ancora, il file
+MAINTAINERS è il posto giusto da dove iniziare. Il file potrebbe non essere
+sempre aggiornato, inoltre, non tutti i sottosistemi sono rappresentati qui.
+Coloro che sono elencati nel file MAINTAINERS potrebbero, in effetti, non
+essere le persone che attualmente svolgono quel determinato ruolo. Quindi,
+quando c'è un dubbio su chi contattare, un trucco utile è quello di usare
+git (git log in particolare) per vedere chi attualmente è attivo all'interno
+del sottosistema interessato. Controllate chi sta scrivendo le patch,
+e chi, se non ci fosse nessuno, sta aggiungendo la propria firma
+(Signed-off-by) a quelle patch. Quelle sono le persone maggiormente
+qualificate per aiutarvi con lo sviluppo di nuovo progetto.
+
+Il compito di trovare il giusto manutentore, a volte, è una tale sfida che
+ha spinto gli sviluppatori del kernel a scrivere uno script che li aiutasse
+in questa ricerca:
+
+::
+
+ .../scripts/get_maintainer.pl
+
+Se questo script viene eseguito con l'opzione "-f" ritornerà il
+manutentore(i) attuale per un dato file o cartella. Se viene passata una
+patch sulla linea di comando, lo script elencherà i manutentori che
+dovrebbero riceverne una copia. Ci sono svariate opzioni che regolano
+quanto a fondo get_maintainer.pl debba cercare i manutentori;
+siate quindi prudenti nell'utilizzare le opzioni più aggressive poiché
+potreste finire per includere sviluppatori che non hanno un vero interesse
+per il codice che state modificando.
+
+Se tutto ciò dovesse fallire, parlare con Andrew Morton potrebbe essere
+un modo efficace per capire chi è il manutentore di un dato pezzo di codice.
+
+Quando pubblicare
+-----------------
+
+Se potete, pubblicate i vostri intenti durante le fasi preliminari, sarà
+molto utile. Descrivete il problema da risolvere e ogni piano che è stato
+elaborato per l'implementazione. Ogni informazione fornita può aiutare
+la comunità di sviluppo a fornire spunti utili per il progetto.
+
+Un evento che potrebbe risultare scoraggiate e che potrebbe accadere in
+questa fase non è il ricevere una risposta ostile, ma, invece, ottenere
+una misera o inesistente reazione. La triste verità è che: (1) gli
+sviluppatori del kernel tendono ad essere occupati, (2) ci sono tante persone
+con grandi progetti e poco codice (o anche solo la prospettiva di
+avere un codice) a cui riferirsi e (3) nessuno è obbligato a revisionare
+o a fare osservazioni in merito ad idee pubblicate da altri. Oltre a
+questo, progetti di alto livello spesso nascondono problematiche che si
+rivelano solo quando qualcuno cerca di implementarle; per questa ragione
+gli sviluppatori kernel preferirebbero vedere il codice.
+
+Quindi, se una richiesta pubblica di commenti riscuote poco successo, non
+pensate che ciò significhi che non ci sia interesse nel progetto.
+Sfortunatamente, non potete nemmeno assumere che non ci siano problemi con
+la vostra idea. La cosa migliore da fare in questa situazione è quella di
+andare avanti e tenere la comunità informata mentre procedete.
+
+Ottenere riscontri ufficiali
+----------------------------
+
+Se il vostro lavoro è stato svolto in un ambiente aziendale - come molto
+del lavoro fatto su Linux - dovete, ovviamente, avere il permesso dei
+dirigenti prima che possiate pubblicare i progetti, o il codice aziendale,
+su una lista di discussione pubblica. La pubblicazione di codice che non
+è stato rilascio espressamente con licenza GPL-compatibile può rivelarsi
+problematico; prima la dirigenza, e il personale legale, troverà una decisione
+sulla pubblicazione di un progetto, meglio sarà per tutte le persone coinvolte.
+
+A questo punto, alcuni lettori potrebbero pensare che il loro lavoro sul
+kernel è preposto a supportare un prodotto che non è ancora ufficialmente
+riconosciuto. Rivelare le intenzioni dei propri datori di lavori in una
+lista di discussione pubblica potrebbe non essere una soluzione valida.
+In questi casi, vale la pena considerare se la segretezza sia necessaria
+o meno; spesso non c'è una reale necessità di mantenere chiusi i progetti di
+sviluppo.
+
+Detto ciò, ci sono anche casi dove l'azienda legittimamente non può rivelare
+le proprie intenzioni in anticipo durante il processo di sviluppo. Le aziende
+che hanno sviluppatori kernel esperti possono scegliere di procedere a
+carte coperte partendo dall'assunto che saranno in grado di evitare, o gestire,
+in futuro, eventuali problemi d'integrazione. Per le aziende senza questo tipo
+di esperti, la migliore opzione è spesso quella di assumere uno sviluppatore
+esterno che revisioni i progetti con un accordo di segretezza.
+La Linux Foundation applica un programma di NDA creato appositamente per
+aiutare le aziende in questa particolare situazione; potrete trovare più
+informazioni sul sito:
+
+ http://www.linuxfoundation.org/en/NDA_program
+
+Questa tipologia di revisione è spesso sufficiente per evitare gravi problemi
+senza che sia richiesta l'esposizione pubblica del progetto.

+
+Scrivere codice corretto
+========================
+
+Nonostante ci sia molto da dire sul processo di creazione, sulla sua solidità
+e sul suo orientamento alla comunità, la prova di ogni progetto di sviluppo
+del kernel si trova nel codice stesso. È il codice che sarà esaminato dagli
+altri sviluppatori ed inserito (o no) nel ramo principale. Quindi è la
+qualità di questo codice che determinerà il successo finale del progetto.
+
+Questa sezione esaminerà il processo di codifica. Inizieremo con uno sguardo
+sulle diverse casistiche nelle quali gli sviluppatori kernel possono
+sbagliare. Poi, l'attenzione si sposterà verso "il fare le cose
+correttamente" e sugli strumenti che possono essere utili in questa missione.
+
+Trappole
+--------
+
+Lo stile del codice
+*******************
+
+Il kernel ha da tempo delle norme sullo stile di codifica che sono descritte in
+:ref:`Documentation/translations/it_IT/process/coding-style.rst <codingstyle>`.
+Per la maggior parte del tempo, la politica descritta in quel file è stata
+praticamente informativa. Ne risulta che ci sia una quantità sostanziale di
+codice nel kernel che non rispetta le linee guida relative allo stile.
+La presenza di quel codice conduce a due distinti pericoli per gli
+sviluppatori kernel.
+
+Il primo di questi è credere che gli standard di codifica del kernel
+non sono importanti e possono non essere applicati. La verità è che
+aggiungere nuovo codice al kernel è davvero difficile se questo non
+rispetta le norme; molti sviluppatori richiederanno che il codice sia
+riformulato prima che anche solo lo revisionino. Una base di codice larga
+quanto il kernel richiede una certa uniformità, in modo da rendere possibile
+per gli sviluppatori una comprensione veloce di ogni sua parte. Non ci sono,
+quindi, più spazi per un codice formattato alla carlona.
+
+Occasionalmente, lo stile di codifica del kernel andrà in conflitto con lo
+stile richiesto da un datore di lavoro. In alcuni casi, lo stile del kernel
+dovrà prevalere prima che il codice venga inserito. Mettere il codice
+all'interno del kernel significa rinunciare a un certo grado di controllo
+in differenti modi - incluso il controllo sul come formattare il codice.
+
+L’altra trappola è quella di pensare che il codice già presente nel kernel
+abbia urgentemente bisogno di essere sistemato. Gli sviluppatori potrebbero
+iniziare a generare patch che correggono lo stile come modo per prendere
+famigliarità con il processo, o come modo per inserire i propri nomi nei
+changelog del kernel – o entrambe. La comunità di sviluppo vede un attività
+di codifica puramente correttiva come "rumore"; queste attività riceveranno
+una fredda accoglienza. Di conseguenza è meglio evitare questo tipo di patch.
+Mentre si lavora su un pezzo di codice è normale correggerne anche lo stile,
+ma le modifiche di stile non dovrebbero essere fatte fini a se stesse.
+
+Il documento sullo stile del codice non dovrebbe essere letto come una legge
+assoluta che non può mai essere trasgredita. Se c’è un a buona ragione
+(per esempio, una linea che diviene poco leggibile se divisa per rientrare
+nel limite di 80 colonne), fatelo e basta.
+
+Notate che potete utilizzare lo strumento “clang-format†per aiutarvi con
+le regole, per una riformattazione automatica e veloce del vostro codice
+e per revisionare interi file per individuare errori nello stile di codifica,
+refusi e possibili miglioramenti. Inoltre è utile anche per classificare gli
+``#includes``, per allineare variabili/macro, per testi derivati ed altri
+compiti del genere. Consultate il file
+:ref:`Documentation/translations/it_IT/process/clang-format.rst <clangformat>`
+per maggiori dettagli
+
+
+Livelli di astrazione
+*********************
+
+
+I professori di Informatica insegnano ai propri studenti a fare ampio uso dei
+livelli di astrazione nel nome della flessibilità e del nascondere informazioni.
+Certo il kernel fa un grande uso dell'astrazione; nessun progetto con milioni
+di righe di codice potrebbe fare altrimenti e sopravvivere. Ma l'esperienza
+ha dimostrato che un'eccessiva o prematura astrazione può rivelarsi dannosa
+al pari di una prematura ottimizzazione. L'astrazione dovrebbe essere usata
+fino al livello necessario e non oltre.
+
+Ad un livello base, considerate una funzione che ha un argomento che viene
+sempre impostato a zero da tutti i chiamanti. Uno potrebbe mantenere
+quell'argomento nell'eventualità qualcuno volesse sfruttare la flessibilità
+offerta. In ogni caso, tuttavia, ci sono buone possibilità che il codice
+che va ad implementare questo argomento aggiuntivo, sia stato rotto in maniera
+sottile, in un modo che non è mai stato notato - perché non è mai stato usato.
+Oppure, quando sorge la necessità di avere più flessibilità, questo argomento
+non la fornisce in maniera soddisfacente. Gli sviluppatori di Kernel,
+sottopongono costantemente patch che vanno a rimuovere gli argomenti
+inutilizzate; anche se, in generale, non avrebbero dovuto essere aggiunti.
+
+I livelli di astrazione che nascondono l'accesso all'hardware -
+spesso per poter usare dei driver su diversi sistemi operativi - vengono
+particolarmente disapprovati. Tali livelli oscurano il codice e possono
+peggiorare le prestazioni; essi non appartengono al kernel Linux.
+
+D'altro canto, se vi ritrovate a dover copiare una quantità significativa di
+codice proveniente da un altro sottosistema del kernel, è tempo di chiedersi
+se, in effetti, non avrebbe più senso togliere parte di quel codice e metterlo
+in una libreria separata o di implementare quella funzionalità ad un livello
+più elevato. Non c'è utilità nel replicare lo stesso codice per tutto
+il kernel.
+
+
+#ifdef e l'uso del preprocessore in generale
+********************************************
+
+Il preprocessore C sembra essere una fonte di attrazione per qualche
+programmatore C, che ci vede una via per ottenere una grande flessibilità
+all'interno di un file sorgente. Ma il preprocessore non è scritto in C,
+e un suo massiccio impiego conduce a un codice che è molto più difficile
+da leggere per gli altri e che rende più difficile il lavoro di verifica del
+compilatore. L'uso eccessivo del preprocessore è praticamente sempre il segno
+di un codice che necessita di un certo lavoro di pulizia.
+
+La compilazione condizionata con #ifdef è, in effetti, un potente strumento,
+ed esso viene usato all'interno del kernel. Ma esiste un piccolo desiderio:
+quello di vedere il codice coperto solo da una leggera spolverata di
+blocchi #ifdef. Come regola generale, quando possibile, l'uso di #ifdef
+dovrebbe essere confinato nei file d'intestazione. Il codice compilato
+condizionatamente può essere confinato a funzioni tali che, nel caso in cui
+il codice non deve essere presente, diventano vuote. Il compilatore poi
+ottimizzerà la chiamata alla funzione vuota rimuovendola. Il risultato è
+un codice molto più pulito, più facile da seguire.
+
+Le macro del preprocessore C presentano una serie di pericoli, inclusi
+valutazioni multiple di espressioni che hanno effetti collaterali e non
+garantiscono una sicurezza rispetto ai tipi. Se siete tentati dal definire
+una macro, considerate l'idea di creare invece una funzione inline. Il codice
+che ne risulterà sarà lo stesso, ma le funzioni inline sono più leggibili,
+non considerano i propri argomenti più volte, e permettono al compilatore di
+effettuare controlli sul tipo degli argomenti e del valore di ritorno.
+
+
+Funzioni inline
+***************
+
+Comunque, anche le funzioni inline hanno i loro pericoli. I programmatori
+potrebbero innamorarsi dell'efficienza percepita derivata dalla rimozione
+di una chiamata a funzione. Queste funzioni, tuttavia, possono ridurre le
+prestazioni. Dato che il loro codice viene replicato ovunque vi sia una
+chiamata ad esse, si finisce per gonfiare le dimensioni del kernel compilato.
+Questi, a turno, creano pressione sulla memoria cache del processore, e questo
+può causare rallentamenti importanti. Le funzioni inline, di norma, dovrebbero
+essere piccole e usate raramente. Il costo di una chiamata a funzione, dopo
+tutto, non è così alto; la creazione di molte funzioni inline è il classico
+esempio di un'ottimizzazione prematura.
+
+In generale, i programmatori del kernel ignorano gli effetti della cache a
+loro rischio e pericolo. Il classico compromesso tempo/spazio teorizzato
+all'inizio delle lezioni sulle strutture dati spesso non si applica
+all'hardware moderno. Lo spazio *è* tempo, in questo senso un programma
+più grande sarà più lento rispetto ad uno più compatto.
+
+I compilatori più recenti hanno preso un ruolo attivo nel decidere se
+una data funzione deve essere resa inline oppure no. Quindi l'uso
+indiscriminato della parola chiave "inline" potrebbe non essere non solo
+eccessivo, ma anche irrilevante.
+
+Sincronizzazione
+****************
+
+Nel maggio 2006, il sistema di rete "Devicescape" fu rilasciato in pompa magna
+sotto la licenza GPL e reso disponibile per la sua inclusione nella ramo
+principale del kernel. Questa donazione fu una notizia bene accolta;
+il supporto per le reti senza fili era considerata, nel migliore dei casi,
+al di sotto degli standard; il sistema Deviscape offrì la promessa di una
+risoluzione a tale situazione. Tuttavia, questo codice non fu inserito nel
+ramo principale fino al giugno del 2007 (2.6.22). Cosa accadde?
+
+Quel codice mostrava numerosi segnali di uno sviluppo in azienda avvenuto
+a porte chiuse. Ma in particolare, un grosso problema fu che non fu
+progettato per girare in un sistema multiprocessore. Prima che questo
+sistema di rete (ora chiamato mac80211) potesse essere inserito, fu necessario
+un lavoro sugli schemi di sincronizzazione.
+
+Una volta, il codice del kernel Linux poteva essere sviluppato senza pensare
+ai problemi di concorrenza presenti nei sistemi multiprocessore. Ora,
+comunque, questo documento è stato scritto su di un portatile dual-core.
+Persino su sistemi a singolo processore, il lavoro svolto per incrementare
+la capacità di risposta aumenterà il livello di concorrenza interno al kernel.
+I giorni nei quali il codice poteva essere scritto senza pensare alla
+sincronizzazione sono da passati tempo.
+
+Ogni risorsa (strutture dati, registri hardware, etc.) ai quali si potrebbe
+avere accesso simultaneo da più di un thread deve essere sincronizzato. Il
+nuovo codice dovrebbe essere scritto avendo tale accortezza in testa;
+riadattare la sincronizzazione a posteriori è un compito molto più difficile.
+Gli sviluppatori del kernel dovrebbero prendersi il tempo di comprendere bene
+le primitive di sincronizzazione, in modo da sceglier lo strumento corretto
+per eseguire un compito. Il codice che presenta una mancanza di attenzione
+alla concorrenza avrà un percorso difficile all'interno del ramo principale.
+
+Regressioni
+***********
+
+Vale la pena menzionare un ultimo pericolo: potrebbe rivelarsi accattivante
+l'idea di eseguire un cambiamento (che potrebbe portare a grandi
+miglioramenti) che porterà ad alcune rotture per gli utenti esistenti.
+Questa tipologia di cambiamento è chiamata "regressione", e le regressioni son
+diventate mal viste nel ramo principale del kernel. Con alcune eccezioni,
+i cambiamenti che causano regressioni saranno fermati se quest'ultime non
+potranno essere corrette in tempo utile. È molto meglio quindi evitare
+la regressione fin dall'inizio.
+
+Spesso si è argomentato che una regressione può essere giustificata se essa
+porta risolve più problemi di quanti non ne crei. Perché, dunque, non fare
+un cambiamento se questo porta a nuove funzionalità a dieci sistemi per
+ognuno dei quali esso determina una rottura? La migliore risposta a questa
+domanda ci è stata fornita da Linus nel luglio 2007:
+
+::
+ Dunque, noi non sistemiamo bachi introducendo nuovi problemi. Quella
+ via nasconde insidie, e nessuno può sapere del tutto se state facendo
+ dei progressi reali. Sono due passi avanti e uno indietro, oppure
+ un passo avanti e due indietro?
+
+(http://lwn.net/Articles/243460/).
+
+Una particolare tipologia di regressione mal vista consiste in una qualsiasi
+sorta di modifica all'ABI dello spazio utente. Una volta che un'interfaccia
+viene esportata verso lo spazio utente, dev'essere supportata all'infinito.
+Questo fatto rende la creazione di interfacce per lo spazio utente
+particolarmente complicato: dato che non possono venir cambiate introducendo
+incompatibilità, esse devono essere fatte bene al primo colpo. Per questa
+ragione sono sempre richieste: ampie riflessioni, documentazione chiara e
+ampie revisioni dell'interfaccia verso lo spazio utente.
+
+
+Strumenti di verifica del codice
+--------------------------------
+Almeno per ora la scrittura di codice priva di errori resta un ideale
+irraggiungibile ai più. Quello che speriamo di poter fare, tuttavia, è
+trovare e correggere molti di questi errori prima che il codice entri nel
+ramo principale del kernel. A tal scopo gli sviluppatori del kernel devono
+mettere insieme una schiera impressionante di strumenti che possano
+localizzare automaticamente un'ampia varietà di problemi. Qualsiasi problema
+trovato dal computer è un problema che non affliggerà l'utente in seguito,
+ne consegue che gli strumenti automatici dovrebbero essere impiegati ovunque
+possibile.
+
+Il primo passo consiste semplicemente nel fare attenzione agli avvertimenti
+proveniente dal compilatore. Versioni moderne di gcc possono individuare
+(e segnalare) un gran numero di potenziali errori. Molto spesso, questi
+avvertimenti indicano problemi reali. Di regola, il codice inviato per la
+revisione non dovrebbe produrre nessun avvertimento da parte del compilatore.
+Per mettere a tacere gli avvertimenti, cercate di comprenderne le cause reali
+e cercate di evitare le "riparazioni" che fan sparire l'avvertimento senza
+però averne trovato la causa.
+
+Tenete a mente che non tutti gli avvertimenti sono disabilitati di default.
+Costruite il kernel con "make EXTRA_CFLAGS=-W" per ottenerli tutti.
+
+Il kernel fornisce differenti opzioni che abilitano funzionalità di debugging;
+molti di queste sono trovano all'interno del sotto menu "kernel hacking".
+La maggior parte di queste opzioni possono essere attivate per qualsiasi
+kernel utilizzato per lo sviluppo o a scopo di test. In particolare dovreste
+attivare:
+
+ - ENABLE_MUST_CHECK e FRAME_WARN per ottenere degli
+ avvertimenti dedicati a problemi come l'uso di interfacce deprecate o
+ l'ignorare un importante valore di ritorno di una funzione. Il risultato
+ generato da questi avvertimenti può risultare verboso, ma non bisogna
+ preoccuparsi per gli avvertimenti provenienti da altre parti del kernel.
+
+ - DEBUG_OBJECTS aggiungerà un codice per tracciare il ciclo di vita di
+ diversi oggetti creati dal kernel e avvisa quando qualcosa viene eseguito
+ fuori controllo. Se state aggiungendo un sottosistema che crea (ed
+ esporta) oggetti complessi propri, considerate l'aggiunta di un supporto
+ al debugging dell'oggetto.
+
+ - DEBUG_SLAB può trovare svariati errori di uso e di allocazione di memoria;
+ esso dovrebbe esser usato dalla maggior parte dei kernel di sviluppo.
+
+ - DEBUG_SPINLOCK, DEBUG_ATOMIC_SLEEP, e DEBUG_MUTEXES troveranno un certo
+ numero di errori comuni di sincronizzazione.
+
+Esistono ancora delle altre opzioni di debugging, di alcune di esse
+discuteremo qui sotto. Alcune di esse hanno un forte impatto e non dovrebbero
+essere usate tutte le volte. Ma qualche volta il tempo speso nell'capire
+le opzioni disponibili porterà ad un risparmio di tempo nel breve termine.
+
+Uno degli strumenti di debugging più tosti è il *locking checker*, o
+"lockdep". Questo strumento traccerà qualsiasi acquisizione e rilascio di
+ogni *lock* (spinlock o mutex) nel sistema, l'ordine con il quale i *lock*
+sono acquisiti in relazione l'uno con l'altro, l'ambiente corrente di
+interruzione, eccetera. Inoltre esso può assicurare che i *lock* vengano
+acquisiti sempre nello stesso ordine, che le stesse assunzioni sulle
+interruzioni si applichino in tutte le occasioni, e così via. In altre parole,
+lockdep può scovare diversi scenari nei quali il sistema potrebbe, in rari
+casi, trovarsi in stallo. Questa tipologia di problema può essere grave
+(sia per gli sviluppatori che per gli utenti) in un sistema in uso; lockdep
+permette di trovare tali problemi automaticamente e in anticipo.
+
+In qualità di programmatore kernel diligente, senza dubbio, dovrete controllare
+il valore di ritorno di ogni operazione (come l'allocazione della memoria)
+poiché esso potrebbe fallire. Il nocciolo della questione è che i percorsi
+di gestione degli errori, con grande probabilità, non sono mai stati
+collaudati del tutto. Il codice collaudato tende ad essere codice bacato;
+potrete quindi essere più a vostro agio con il vostro codice se tutti questi
+percorsi fossero stati verificati un po' di volte.
+
+Il kernel fornisce un framework per l'inserimento di fallimenti che fa
+esattamente al caso, specialmente dove sono coinvolte allocazioni di memoria.
+Con l'opzione per l'inserimento dei fallimenti abilitata, una certa percentuale
+di allocazione di memoria sarà destinata al fallimento; questi fallimenti
+possono essere ridotti ad uno specifico pezzo di codice. Procedere con
+l'inserimento dei fallimenti attivo permette al programmatore di verificare
+come il codice risponde quando le cose vanno male. Consultate:
+Documentation/fault-injection/fault-injection.txt per avere maggiori
+informazioni su come utilizzare questo strumento.
+
+Altre tipologie di errori possono essere riscontrati con lo strumento di
+analisi statica "sparse". Con Sparse, il programmatore può essere avvisato
+circa la confusione tra gli indirizzi dello spazio utente e dello spazio
+kernel, un miscuglio fra quantità big-endian e little-endian, il passaggio
+di un valore intero dove ci sia aspetta un gruppo di flag, e così via.
+Sparse deve essere installato separatamente (se il vostra distribuzione non
+lo prevede, potete trovarlo su https://sparse.wiki.kernel.org/index.php/Main_Page);
+può essere attivato sul codice aggiungendo "C=1" al comando make.
+
+Lo strumento "Coccinelle" (http://coccinelle.lip6.fr/) è in grado di trovare
+una vasta varietà di potenziali problemi di codifica; e può inoltre proporre
+soluzioni per risolverli. Un buon numero di "patch semantiche" per il kernel
+sono state preparate nella cartella scripts/coccinelle; utilizzando
+"make coccicheck" esso percorrerà tali patch semantiche e farà rapporto su
+qualsiasi problema trovato. Per maggiori informazioni, consultate
+:ref:`Documentation/dev-tools/coccinelle.rst <devtools_coccinelle>`.
+
+Altri errori di portabilità sono meglio scovati compilando il vostro codice
+per altre architetture. Se non vi accade di avere un sistema S/390 o una
+scheda di sviluppo Blackfin sotto mano, potete comunque continuare la fase
+di compilazione. Un vasto numero di cross-compilatori per x86 possono
+essere trovati al sito:
+
+ http://www.kernel.org/pub/tools/crosstool/
+
+Il tempo impiegato nell'installare e usare questi compilatori sarà d'aiuto
+nell'evitare situazioni imbarazzanti nel futuro.
+
+
+Documentazione
+--------------
+
+La documentazione è spesso stata più un'eccezione che una regola nello
+sviluppo del kernel. Nonostante questo, un'adeguata documentazione aiuterà
+a facilitare l'inserimento di nuovo codice nel kernel, rende la vita più
+facile per gli altri sviluppatori e sarà utile per i vostri utenti. In molti
+casi, la documentazione è divenuta sostanzialmente obbligatoria.
+
+La prima parte di documentazione per qualsiasi patch è il suo changelog.
+Questi dovrebbero descrivere le problematiche risolte, la tipologia di
+soluzione, le persone che lavorano alla patch, ogni effetto rilevante
+sulle prestazioni e tutto ciò che può servire per la comprensione della
+patch. Assicuratevi che il changelog dica *perché*, vale la pena aggiungere
+la patch; un numero sorprendente di sviluppatori sbaglia nel fornire tale
+informazione.
+
+Qualsiasi codice che aggiunge una nuova interfaccia in spazio utente - inclusi
+nuovi file in sysfs o /proc - dovrebbe includere la documentazione di tale
+interfaccia così da permette agli sviluppatori dello spazio utente di sapere
+con cosa stanno lavorando. Consultate: Documentation/ABI/README per avere una
+descrizione di come questi documenti devono essere impostati e quali
+informazioni devono essere fornite.
+
+Il file :ref:`Documentation/translations/it_IT/admin-guide/kernel-parameters.rst <kernelparameters>`
+descrive tutti i parametri di avvio del kernel. Ogni patch che aggiunga
+nuovi parametri dovrebbe aggiungere nuove voci a questo file.
+
+Ogni nuova configurazione deve essere accompagnata da un testo di supporto
+che spieghi chiaramente le opzioni e spieghi quando l'utente potrebbe volerle
+selezionare.
+
+Per molti sottosistemi le informazioni sull'API interna sono documentate sotto
+forma di commenti formattati in maniera particolare; questi commenti possono
+essere estratti e formattati in differenti modi attraverso lo script
+"kernel-doc". Se state lavorando all'interno di un sottosistema che ha
+commenti kerneldoc dovreste mantenerli e aggiungerli, in maniera appropriata,
+per le funzioni disponibili esternamente. Anche in aree che non sono molto
+documentate, non c'è motivo per non aggiungere commenti kerneldoc per il
+futuro; infatti, questa può essere un'attività utile per sviluppatori novizi
+del kernel. Il formato di questi commenti, assieme alle informazione su come
+creare modelli per kerneldoc, possono essere trovati in
+:ref:`Documentation/translations/it_IT/doc-guide/ <doc_guide>`.
+
+Chiunque legga un ammontare significativo di codice kernel noterà che, spesso,
+i commenti si fanno maggiormente notare per la loro assenza. Ancora una volta,
+le aspettative verso il nuovo codice sono più alte rispetto al passato;
+inserire codice privo di commenti sarà più difficile. Detto ciò, va aggiunto
+che non si desiderano commenti prolissi per il codice. Il codice dovrebbe
+essere, di per sé, leggibile, con dei commenti che spieghino gli aspetti più
+sottili.
+
+Determinate cose dovrebbero essere sempre commentate. L'uso di barriere
+di memoria dovrebbero essere accompagnate da una riga che spieghi perché sia
+necessaria. Le regole di sincronizzazione per le strutture dati, generalmente,
+necessitano di una spiegazioni da qualche parte. Le strutture dati più
+importanti, in generale, hanno bisogno di una documentazione onnicomprensiva.
+Le dipendenze che non sono ovvie tra bit separati di codice dovrebbero essere
+indicate. Tutto ciò che potrebbe indurre un inserviente del codice a fare
+una "pulizia" incorretta, ha bisogno di un commento che dica perché è stato
+fatto in quel modo. E così via.
+
+Cambiamenti interni dell'API
+----------------------------
+
+L'interfaccia binaria fornita dal kernel allo spazio utente non può essere
+rotta tranne che in circostanze eccezionali. L'interfaccia di programmazione
+interna al kernel, invece, è estremamente fluida e può essere modificata al
+bisogno. Se vi trovate a dover lavorare attorno ad un'API del kernel o
+semplicemente non state utilizzando una funzionalità offerta perché questa
+non rispecchia i vostri bisogni, allora questo potrebbe essere un segno che
+l'API ha bisogno di essere cambiata. In qualità di sviluppatore del kernel,
+hai il potere di fare questo tipo di modifica.
+
+Ci sono ovviamente alcuni punti da cogliere. I cambiamenti API possono essere
+fatti, ma devono essere giustificati. Quindi ogni patch che porta ad una
+modifica dell'API interna dovrebbe essere accompagnata da una descrizione
+della modifica in sé e del perché essa è necessaria. Questo tipo di
+cambiamenti dovrebbero, inoltre, essere fatti in una patch separata, invece di
+essere sepolti all'interno di una patch più grande.
+
+L'altro punto da cogliere consiste nel fatto che uno sviluppatore che
+modifica l'API deve, in generale, essere responsabile della correzione
+di tutto il codice del kernel che viene rotto per via della sua modifica.
+Per una funzione ampiamente usata, questo compito può condurre letteralmente
+a centinaia o migliaia di modifiche, molte delle quali sono in conflitto con
+il lavoro svolto da altri sviluppatori. Non c'è bisogno di dire che questo
+può essere un lavoro molto grosso, quindi è meglio essere sicuri che la
+motivazione sia ben solida. Notate che lo strumento Coccinelle può fornire
+un aiuto con modifiche estese dell'API.
+
+Quando viene fatta una modifica API incompatibile, una persona dovrebbe,
+quando possibile, assicurarsi che quel codice non aggiornato sia trovato
+dal compilatore. Questo vi aiuterà ad essere sicuri d'avere trovato,
+tutti gli usi di quell'interfaccia. Inoltre questo avviserà gli sviluppatori
+di codice fuori dal kernel che c'è un cambiamento per il quale è necessario del
+lavoro. Il supporto al codice fuori dal kernel non è qualcosa di cui gli
+sviluppatori del kernel devono preoccuparsi, ma non dobbiamo nemmeno rendere
+più difficile del necessario la vita agli sviluppatori di questo codice.

+
+Pubblicare modifiche
+====================
+
+Prima o poi arriva il momento in cui il vostro lavoro è pronto per essere
+presentato alla comunità per una revisione ed eventualmente per la sua
+inclusione nel ramo principale del kernel. Com'era prevedibile,
+la comunità di sviluppo del kernel ha elaborato un insieme di convenzioni
+e di procedure per la pubblicazione delle patch; seguirle renderà la vita
+più facile a tutti quanti. Questo documento cercherà di coprire questi
+argomenti con un ragionevole livello di dettaglio; più informazioni possono
+essere trovare nella cartella 'Documentation', nei file
+:ref:`translations/it_IT/process/submitting-patches.rst <it_submittingpatches>`,
+:ref:`translations/it_IT/process/submitting-drivers.rst <it_submittingdrivers>`, e
+:ref:`translations/it_IT/process/submit-checklist.rst <it_submitchecklist>`.
+
+
+Quando pubblicarle
+------------------
+
+C'è sempre una certa resistenza nel pubblicare patch finché non sono
+veramente "pronte". Per semplici patch questo non è un problema.
+Ma quando il lavoro è di una certa complessità, c'è molto da guadagnare
+dai riscontri che la comunità può darvi prima che completiate il lavoro.
+Dovreste considerare l'idea di pubblicare un lavoro incompleto, o anche
+preparare un ramo git disponibile agli sviluppatori interessati, cosicché
+possano stare al passo col vostro lavoro in qualunque momento.
+
+Quando pubblicate del codice che non è considerato pronto per l'inclusione,
+è bene che lo diciate al momento della pubblicazione. Inoltre, aggiungete
+informazioni sulle cose ancora da sviluppare e sui problemi conosciuti.
+Poche persone guarderanno delle patch che si sa essere fatte a metà,
+ma quelli che lo faranno penseranno di potervi aiutare a condurre il vostro
+sviluppo nella giusta direzione.
+
+
+Prima di creare patch
+---------------------
+
+Ci sono un certo numero di cose che dovreste fare prima di considerare
+l'invio delle patch alla comunità di sviluppo. Queste cose includono:
+
+ - Verificare il codice fino al massimo che vi è consentito. Usate gli
+ strumenti di debug del kernel, assicuratevi che il kernel compili con
+ tutte le più ragionevoli combinazioni d'opzioni, usate cross-compilatori
+ per compilare il codice per differenti architetture, eccetera.
+
+ - Assicuratevi che il vostro codice sia conforme alla linee guida del
+ kernel sullo stile del codice.
+
+ - La vostra patch ha delle conseguenze in termini di prestazioni?
+ Se è così, dovreste eseguire dei *benchmark* che mostrino il loro
+ impatto (anche positivo); un riassunto dei risultati dovrebbe essere
+ incluso nella patch.
+
+ - Siate certi d'avere i diritti per pubblicare il codice. Se questo
+ lavoro è stato fatto per un datore di lavoro, egli avrà dei diritti su
+ questo lavoro e dovrà quindi essere d'accordo alla sua pubblicazione
+ con una licenza GPL
+
+Come regola generale, pensarci un po' di più prima di inviare il codice
+ripaga quasi sempre lo sforzo.
+
+
+Preparazione di una patch
+-------------------------
+
+La preparazione delle patch per la pubblicazione può richiedere una quantità
+di lavoro significativa, ma, ripetiamolo ancora, generalmente sconsigliamo
+di risparmiare tempo in questa fase, anche sul breve periodo.
+
+Le patch devono essere preparate per una specifica versione del kernel.
+Come regola generale, una patch dovrebbe basarsi sul ramo principale attuale
+così come lo si trova nei sorgenti git di Linus. Quando vi basate sul ramo
+principale, cominciate da un punto di rilascio ben noto - uno stabile o
+un -rc - piuttosto che creare il vostro ramo da quello principale in un punto
+a caso.
+
+Per facilitare una revisione e una verifica più estesa, potrebbe diventare
+necessaria la produzione di versioni per -mm, linux-next o i sorgenti di un
+sottosistema. Basare questa patch sui suddetti sorgenti potrebbe richiedere
+un lavoro significativo nella risoluzione dei conflitti e nella correzione dei
+cambiamenti di API; questo potrebbe variare a seconda dell'area d'interesse
+della vostra patch e da quello che succede altrove nel kernel.
+
+Solo le modifiche più semplici dovrebbero essere preparate come una singola
+patch; tutto il resto dovrebbe essere preparato come una serie logica di
+modifiche. Spezzettare le patch è un po' un'arte; alcuni sviluppatori
+passano molto tempo nel capire come farlo in modo che piaccia alla comunità.
+Ci sono alcune regole spannometriche, che comunque possono aiutare
+considerevolmente:
+
+ - La serie di patch che pubblicherete, quasi sicuramente, non sarà
+ come quella che trovate nel vostro sistema di controllo di versione.
+ Invece, le vostre modifiche dovranno essere considerate nella loro forma
+ finale, e quindi separate in parti che abbiano un senso. Gli sviluppatori
+ sono interessati in modifiche che siano discrete e indipendenti, non
+ alla strada che avete percorso per ottenerle.
+
+ - Ogni modifica logicamente indipendente dovrebbe essere preparata come una
+ patch separata. Queste modifiche possono essere piccole ("aggiunto un
+ campo in questa struttura") o grandi (l'aggiunta di un driver nuovo,
+ per esempio), ma dovrebbero essere concettualmente piccole da permettere
+ una descrizione in una sola riga. Ogni patch dovrebbe fare modifiche
+ specifiche che si possano revisionare indipendentemente e di cui si possa
+ verificare la veridicità.
+
+ - Giusto per riaffermare quando detto sopra: non mischiate diversi tipi di
+ modifiche nella stessa patch. Se una modifica corregge un baco critico
+ per la sicurezza, riorganizza alcune strutture, e riformatta il codice,
+ ci sono buone probabilità che venga ignorata e che la correzione importante
+ venga persa.
+
+ - Ogni modifica dovrebbe portare ad un kernel che compila e funziona
+ correttamente; se la vostra serie di patch si interrompe a metà il
+ risultato dovrebbe essere comunque un kernel funzionante. L'applicazione
+ parziale di una serie di patch è uno scenario comune nel quale il
+ comando "git bisect" viene usato per trovare delle regressioni; se il
+ risultato è un kernel guasto, renderete la vita degli sviluppatori più
+ difficile così come quella di chi s'impegna nel nobile lavoro di
+ scovare i problemi.
+
+ - Però, non strafate. Una volta uno sviluppatore pubblicò una serie di 500
+ patch che modificavano un unico file - un atto che non lo rese la persona
+ più popolare sulla lista di discussione del kernel. Una singola patch
+ può essere ragionevolmente grande fintanto che contenga un singolo
+ cambiamento *logico*.
+
+ - Potrebbe essere allettante l'idea di aggiungere una nuova infrastruttura
+ come una serie di patch, ma di lasciare questa infrastruttura inutilizzata
+ finché l'ultima patch della serie non abilita tutto quanto. Quando è
+ possibile, questo dovrebbe essere evitato; se questa serie aggiunge delle
+ regressioni, "bisect" indicherà quest'ultima patch come causa del
+ problema anche se il baco si trova altrove. Possibilmente, quando una
+ patch aggiunge del nuovo codice dovrebbe renderlo attivo immediatamente.
+
+Lavorare per creare la serie di patch perfetta potrebbe essere frustrante
+perché richiede un certo tempo e soprattutto dopo che il "vero lavoro" è
+già stato fatto. Quando ben fatto, comunque, è tempo ben speso.
+
+
+Formattazione delle patch e i changelog
+---------------------------------------
+
+Quindi adesso avete una serie perfetta di patch pronte per la pubblicazione,
+ma il lavoro non è davvero finito. Ogni patch deve essere preparata con
+un messaggio che spieghi al resto del mondo, in modo chiaro e veloce,
+il suo scopo. Per ottenerlo, ogni patch sarà composta dai seguenti elementi:
+
+ - Un campo opzionale "From" col nome dell'autore della patch. Questa riga
+ è necessaria solo se state passando la patch di qualcun altro via email,
+ ma nel dubbio non fa di certo male aggiungerlo.
+
+ - Una descrizione di una riga che spieghi cosa fa la patch. Questo
+ messaggio dovrebbe essere sufficiente per far comprendere al lettore lo
+ scopo della patch senza altre informazioni. Questo messaggio,
+ solitamente, presenta in testa il nome del sottosistema a cui si riferisce,
+ seguito dallo scopo della patch. Per esempio:
+
+ ::
+
+ gpio: fix build on CONFIG_GPIO_SYSFS=n
+
+ - Una riga bianca seguita da una descrizione dettagliata della patch.
+ Questa descrizione può essere lunga tanto quanto serve; dovrebbe spiegare
+ cosa fa e perché dovrebbe essere aggiunta al kernel.
+
+ - Una o più righe etichette, con, minimo, una riga *Signed-off-by:*
+ col nome dall'autore della patch. Queste etichette verranno descritte
+ meglio più avanti.
+
+Gli elementi qui sopra, assieme, formano il changelog di una patch.
+Scrivere un buon changelog è cruciale ma è spesso un'arte trascurata;
+vale la pena spendere qualche parola in più al riguardo. Quando scrivete
+un changelog dovreste tenere ben presente che molte persone leggeranno
+le vostre parole. Queste includono i manutentori di un sotto-sistema, e i
+revisori che devono decidere se la patch debba essere inclusa o no,
+le distribuzioni e altri manutentori che cercano di valutare se la patch
+debba essere applicata su kernel più vecchi, i cacciatori di bachi che si
+chiederanno se la patch è la causa di un problema che stanno cercando,
+gli utenti che vogliono sapere com'è cambiato il kernel, e molti altri.
+Un buon changelog fornisce le informazioni necessarie a tutte queste
+persone nel modo più diretto e conciso possibile.
+
+A questo scopo, la riga riassuntiva dovrebbe descrivere gli effetti della
+modifica e la motivazione della patch nel modo migliore possibile nonostante
+il limite di una sola riga. La descrizione dettagliata può spiegare meglio
+i temi e fornire maggiori informazioni. Se una patch corregge un baco,
+citate, se possibile, il commit che lo introdusse (e per favore, quando
+citate un commit aggiungete sia il suo identificativo che il titolo),
+Se il problema è associabile ad un file di log o all' output del compilatore,
+includeteli al fine d'aiutare gli altri a trovare soluzioni per lo stesso
+problema. Se la modifica ha lo scopo di essere di supporto a sviluppi
+successivi, ditelo. Se le API interne vengono cambiate, dettagliate queste
+modifiche e come gli altri dovrebbero agire per applicarle. In generale,
+più riuscirete ad entrare nei panni di tutti quelli che leggeranno il
+vostro changelog, meglio sarà il changelog (e il kernel nel suo insieme).
+
+Non serve dirlo, un changelog dovrebbe essere il testo usato nel messaggio
+di commit in un sistema di controllo di versione. Sarà seguito da:
+
+ - La patch stessa, nel formato unificato per patch ("-u"). Usare
+ l'opzione "-p" assocerà alla modifica il nome della funzione alla quale
+ si riferisce, rendendo il risultato più facile da leggere per gli altri.
+
+Dovreste evitare di includere nelle patch delle modifiche per file
+irrilevanti (quelli generati dal processo di generazione, per esempio, o i file
+di backup del vostro editor). Il file "dontdiff" nella cartella Documentation
+potrà esservi d'aiuto su questo punto; passatelo a diff con l'opzione "-X".
+
+Le etichette sopra menzionante sono usate per descrivere come i vari
+sviluppatori sono stati associati allo sviluppo di una patch. Sono descritte
+in dettaglio nel documento :ref:`translations/it_IT/process/submitting-patches.rst <it_submittingpatches>`;
+quello che segue è un breve riassunto. Ognuna di queste righe ha il seguente
+formato:
+
+::
+
+ tag: Full Name <email address> optional-other-stuff
+
+Le etichette in uso più comuni sono:
+
+ - Signed-off-by: questa è la certificazione che lo sviluppatore ha il diritto
+ di sottomettere la patch per l'integrazione nel kernel. Questo rappresenta
+ il consenso verso il certificato d'origine degli sviluppatori, il testo
+ completo potrà essere trovato in
+ :ref:`Documentation/translations/it_IT/process/submitting-patches.rst <it_submittingpatches>`.
+ Codice che non presenta una firma appropriata non potrà essere integrato.
+
+ - Co-developed-by: indica che la patch è stata sviluppata anche da un altro
+ sviluppatore assieme all'autore originale. Questo è utile quando più
+ persone lavorano sulla stessa patch. Da notare che questa persona deve
+ avere anche una riga "Signed-off-by:" nella patch.
+
+ - Acked-by: indica il consenso di un altro sviluppatore (spesso il manutentore
+ del codice in oggetto) all'integrazione della patch nel kernel.
+
+ - Tested-by: menziona la persona che ha verificato la patch e l'ha trovata
+ funzionante.
+
+ - Reviwed-by: menziona lo sviluppatore che ha revisionato la patch; per
+ maggiori dettagli leggete la dichiarazione dei revisori in
+ :ref:`Documentation/translations/it_IT/process/submitting-patches.rst <it_submittingpatches>`
+
+ - Reported-by: menziona l'utente che ha riportato il problema corretto da
+ questa patch; quest'etichetta viene usata per dare credito alle persone
+ che hanno verificato il codice e ci hanno fatto sapere quando le cose non
+ funzionavano correttamente.
+
+ - Cc: la persona menzionata ha ricevuto una copia della patch ed ha avuto
+ l'opportunità di commentarla.
+
+State attenti ad aggiungere queste etichette alla vostra patch: solo
+"Cc:" può essere aggiunta senza il permesso esplicito della persona menzionata.
+
+Inviare la modifica
+-------------------
+
+Prima di inviare la vostra patch, ci sarebbero ancora un paio di cose di cui
+dovreste aver cura:
+
+ - Siete sicuri che il vostro programma di posta non corromperà le patch?
+ Le patch che hanno spazi bianchi in libertà o andate a capo aggiunti
+ dai programmi di posta non funzioneranno per chi le riceve, e spesso
+ non verranno nemmeno esaminate in dettaglio. Se avete un qualsiasi dubbio,
+ inviate la patch a voi stessi e verificate che sia integra.
+
+ :ref:`Documentation/translations/it_IT/process/email-clients.rst <it_email_clients>`
+ contiene alcuni suggerimenti utili sulla configurazione dei programmi
+ di posta al fine di inviare patch.
+
+ - Siete sicuri che la vostra patch non contenga sciocchi errori? Dovreste
+ sempre processare le patch con scripts/checkpatch.pl e correggere eventuali
+ problemi riportati. Per favore tenete ben presente che checkpatch.pl non è
+ più intelligente di voi, nonostante sia il risultato di un certa quantità di
+ ragionamenti su come debba essere una patch per il kernel. Se seguire
+ i suggerimenti di checkpatch.pl rende il codice peggiore, allora non fatelo.
+
+Le patch dovrebbero essere sempre inviate come testo puro. Per favore non
+inviatele come allegati; questo rende molto più difficile, per i revisori,
+citare parti della patch che si vogliono commentare. Invece, mettete la vostra
+patch direttamente nel messaggio.
+
+Quando inviate le patch, è importante inviarne una copia a tutte le persone che
+potrebbero esserne interessate. Al contrario di altri progetti, il kernel
+incoraggia le persone a peccare nell'invio di tante copie; non presumente che
+le persone interessate vedano i vostri messaggi sulla lista di discussione.
+In particolare le copie dovrebbero essere inviate a:
+
+ - I manutentori dei sottosistemi affetti della modifica. Come descritto
+ in precedenza, il file MAINTAINERS è il primo luogo dove cercare i nomi
+ di queste persone.
+
+ - Altri sviluppatori che hanno lavorato nello stesso ambiente - specialmente
+ quelli che potrebbero lavorarci proprio ora. Usate git potrebbe essere
+ utile per vedere chi altri ha modificato i file su cui state lavorando.
+
+ - Se state rispondendo a un rapporto su un baco, o a una richiesta di
+ funzionalità, includete anche gli autori di quei rapporti/richieste.
+
+ - Inviate una copia alle liste di discussione interessate, o, se nient'altro
+ è adatto, alla lista linux-kernel
+
+ - Se state correggendo un baco, pensate se la patch dovrebbe essere inclusa
+ nel prossimo rilascio stabile. Se è così, la lista di discussione
+ stable@vger.kernel.org dovrebbe riceverne una copia. Aggiungete anche
+ l'etichetta "Cc: stable@vger.kernel.org" nella patch stessa; questo
+ permetterà alla squadra *stable* di ricevere una notifica quando questa
+ correzione viene integrata nel ramo principale.
+
+Quando scegliete i destinatari della patch, è bene avere un'idea di chi
+pensiate che sia colui che, eventualmente, accetterà la vostra patch e
+la integrerà. Nonostante sia possibile inviare patch direttamente a
+Linus Torvalds, e lasciare che sia lui ad integrarle,solitamente non è la
+strada migliore da seguire. Linus è occupato, e ci sono dei manutentori di
+sotto-sistema che controllano una parte specifica del kernel. Solitamente,
+vorreste che siano questi manutentori ad integrare le vostre patch. Se non
+c'è un chiaro manutentore, l'ultima spiaggia è spesso Andrew Morton.
+
+Le patch devono avere anche un buon oggetto. Il tipico formato per l'oggetto
+di una patch assomiglia a questo:
+
+::
+
+ [PATCH nn/mm] subsys: one-line description of the patch
+
+dove "nn" è il numero ordinale della patch, "mm" è il numero totale delle patch
+nella serie, e "subsys" è il nome del sottosistema interessato. Chiaramente,
+nn/mm può essere omesso per una serie composta da una singola patch.
+
+Se avete una significative serie di patch, è prassi inviare una descrizione
+introduttiva come parte zero. Tuttavia questa convenzione non è universalmente
+seguita; se la usate, ricordate che le informazioni nell'introduzione non
+faranno parte del changelog del kernel. Quindi per favore, assicuratevi che
+ogni patch abbia un changelog completo.
+
+In generale, la seconda parte e quelle successive di una patch "composta"
+dovrebbero essere inviate come risposta alla prima, cosicché vengano viste
+come un unico *thread*. Strumenti come git e quilt hanno comandi per inviare
+gruppi di patch con la struttura appropriata. Se avete una serie lunga
+e state usando git, per favore state alla larga dall'opzione --chain-reply-to
+per evitare di creare un annidamento eccessivo.

+Completamento
+=============
+
+A questo punto, avete seguito le linee guida fino a questo punto e, con
+l'aggiunta delle vostre capacità ingegneristiche, avete pubblicato una serie
+perfetta di patch. Uno dei più grandi errori che possono essere commessi
+persino da sviluppatori kernel esperti è quello di concludere che il
+lavoro sia ormai finito. In verità, la pubblicazione delle patch
+simboleggia una transizione alla fase successiva del processo, con,
+probabilmente, ancora un po' di lavoro da fare.
+
+È raro che una modifica sia così bella alla sua prima pubblicazione che non
+ci sia alcuno spazio di miglioramento. Il programma di sviluppo del kernel
+riconosce questo fatto e quindi, è fortemente orientato al miglioramento
+del codice pubblicato. Voi, in qualità di autori del codice, dovrete
+lavorare con la comunità del kernel per assicurare che il vostro codice
+mantenga gli standard qualitativi richiesti. Un fallimento in questo
+processo è quasi come impedire l'inclusione delle vostre patch nel
+ramo principale.
+
+Lavorare con i revisori
+=======================
+
+Una patch che abbia una certa rilevanza avrà ricevuto numerosi commenti
+da parte di altri sviluppatori dato che avranno revisionato il codice.
+Lavorare con i revisori può rivelarsi, per molti sviluppatori, la parte
+più intimidatoria del processo di sviluppo del kernel. La vita può esservi
+resa molto più facile se tenete presente alcuni dettagli:
+
+ - Se avete descritto la vostra modifica correttamente, i revisori ne
+ comprenderanno il valore e il perché vi siete presi il disturbo di
+ scriverla. Ma tale valore non li tratterrà dal porvi una domanda
+ fondamentale: come verrà mantenuto questo codice nel kernel nei prossimi
+ cinque o dieci anni? Molti dei cambiamenti che potrebbero esservi
+ richiesti - da piccoli problemi di stile a sostanziali ristesure -
+ vengono dalla consapevolezza che Linux resterà in circolazione e in
+ continuo sviluppo ancora per diverse decadi.
+
+ - La revisione del codice è un duro lavoro, ed è un mestiere poco
+ riconosciuto; le persone ricordano chi ha scritto il codice, ma meno
+ fama è attribuita a chi lo ha revisionato. Quindi i revisori potrebbero
+ divenire burberi, specialmente quando vendono i medesimi errori venire
+ fatti ancora e ancora. Se ricevete una revisione che vi sembra abbia
+ un tono arrabbiato, insultante o addirittura offensivo, resistente alla
+ tentazione di rispondere a tono. La revisione riguarda il codice e non
+ la persona, e i revisori non vi stanno attaccando personalmente.
+
+ - Similarmente, i revisori del codice non stanno cercando di promuovere
+ i loro interessi a vostre spese. Gli sviluppatori del kernel spesso si
+ aspettano di lavorare sul kernel per anni, ma sanno che il loro datore
+ di lavoro può cambiare. Davvero, senza praticamente eccezioni, loro
+ stanno lavorando per la creazione del miglior kernel possibile; non
+ stanno cercando di creare un disagio ad aziende concorrenti.
+
+Quello che si sta cercando di dire è che, quando i revisori vi inviano degli
+appunti dovete fare attenzione alle osservazioni tecniche che vi stanno
+facendo. Non lasciate che il loro modo di esprimersi o il vostro orgoglio
+impediscano che ciò accada. Quando avete dei suggerimenti sulla revisione,
+prendetevi il tempo per comprendere cosa il revisore stia cercando di
+comunicarvi. Se possibile, sistemate le cose che il revisore vi chiede di
+modificare. E rispondete al revisore ringraziandolo e spiegando come
+intendete fare.
+
+Notate che non dovete per forza essere d'accordo con ogni singola modifica
+suggerita dai revisori. Se credete che il revisore non abbia compreso
+il vostro codice, spiegateglielo. Se avete un'obiezione tecnica da fargli
+su di una modifica suggerita, spiegatela inserendo anche la vostra soluzione
+al problema. Se la vostra spiegazione ha senso, il revisore la accetterà.
+Tuttavia, la vostra motivazione potrebbe non essere del tutto persuasiva,
+specialmente se altri iniziano ad essere d'accordo con il revisore.
+Prendetevi quindi un po' di tempo per pensare ancora alla cosa. Può risultare
+facile essere accecati dalla propria soluzione al punto che non realizzate che
+c'è qualcosa di fondamentalmente sbagliato o, magari, non state nemmeno
+risolvendo il problema giusto.
+
+Andrew Morton suggerisce che ogni suggerimento di revisione che non è
+presente nella modifica del codice dovrebbe essere inserito in un commento
+aggiuntivo; ciò può essere d'aiuto ai futuri revisori nell'evitare domande
+che sorgono al primo sguardo.
+
+Un errore fatale è quello di ignorare i commenti di revisione nella speranza
+che se ne andranno. Non andranno via. Se pubblicherete nuovamente il
+codice senza aver risposto ai commenti ricevuti, probabilmente le vostre
+modifiche non andranno da nessuna parte.
+
+Parlando di ripubblicazione del codice: per favore tenete a mente che i
+revisori non ricorderanno tutti i dettagli del codice che avete pubblicato
+l'ultima volta. Quindi è sempre una buona idea quella di ricordare ai
+revisori le questioni sollevate precedetemene e come le avete risolte.
+I revisori non dovrebbero star lì a cercare all'interno degli archivi per
+famigliarizzare con ciò che è stato detto l'ultima volta; se li aiutate
+in questo senso, saranno di umore migliore quando riguarderanno il vostro
+codice.
+
+Se invece avete cercato di far tutto correttamente ma le cose continuano
+a non andar bene? Molti disaccordi di natura tecnica possono essere risolti
+attraverso la discussione, ma ci sono volte dove qualcuno deve prendere
+una decisione. Se credete veramente che tale decisione andrà contro di voi
+ingiustamente, potete sempre tentare di rivolgervi a qualcuno più
+in alto di voi. Per cose di questo genere la persona con più potere è
+Andrew Morton. Andrew è una figura molto rispettata all'interno della
+comunità di sviluppo del kernel; lui può spesso sbrogliare situazioni che
+sembrano irrimediabilmente bloccate. Rivolgersi ad Andrew non deve essere
+fatto alla leggera, e non deve essere fatto prima di aver esplorato tutte
+le altre alternative. E tenete a mente, ovviamente, che nemmeno lui
+potrebbe non essere d'accordo con voi.
+
+Cosa accade poi
+===============
+
+Se la modifica è ritenuta un elemento valido da essere aggiunta al kernel,
+e una volta che la maggior parte degli appunti dei revisori sono stati
+sistemati, il passo successivo solitamente è quello di entrare in un
+sottosistema gestito da un manutentore. Come ciò avviene dipende dal
+sottosistema medesimo; ogni manutentore ha il proprio modo di fare le cose.
+In particolare, ci potrebbero essere diversi sorgenti - uno, magari, dedicato
+alle modifiche pianificate per la finestra di fusione successiva, e un altro
+per il lavoro di lungo periodo.
+
+Per le modifiche proposte in aree per le quali non esiste un sottosistema
+preciso (modifiche di gestione della memoria, per esempio), i sorgenti di
+ripiego finiscono per essere -mm. Ed anche le modifiche che riguardano
+più sottosistemi possono finire in quest'ultimo.
+
+L'inclusione nei sorgenti di un sottosistema può comportare per una patch,
+un alto livello di visibilità. Ora altri sviluppatori che stanno lavorando
+in quei medesimi sorgenti avranno le vostre modifiche. I sottosistemi
+solitamente riforniscono anche Linux-next, rendendo i propri contenuti
+visibili all'intera comunità di sviluppo. A questo punto, ci sono buone
+possibilità per voi di ricevere ulteriori commenti da un nuovo gruppo di
+revisori; anche a questi commenti dovrete rispondere come avete già fatto per
+gli altri.
+
+Ciò che potrebbe accadere a questo punto, in base alla natura della vostra
+modifica, riguarda eventuali conflitti con il lavoro svolto da altri.
+Nella peggiore delle situazioni, i conflitti più pesanti tra modifiche possono
+concludersi con la messa a lato di alcuni dei lavori svolti cosicché le
+modifiche restanti possano funzionare ed essere integrate. Altre volte, la
+risoluzione dei conflitti richiederà del lavoro con altri sviluppatori e,
+possibilmente, lo spostamento di alcune patch da dei sorgenti a degli altri
+in modo da assicurare che tutto sia applicato in modo pulito. Questo lavoro
+può rivelarsi una spina nel fianco, ma consideratevi fortunati: prima
+dell'avvento dei sorgenti linux-next, questi conflitti spesso emergevano solo
+durante l'apertura della finestra di integrazione e dovevano essere smaltiti
+in fretta. Ora essi possono essere risolti comodamente, prima dell'apertura
+della finestra.
+
+Un giorno, se tutto va bene, vi collegherete e vedrete che la vostra patch
+è stata inserita nel ramo principale de kernel. Congratulazioni! Terminati
+i festeggiamenti (nel frattempo avrete inserito il vostro nome nel file
+MAINTAINERS) vale la pena ricordare una piccola cosa, ma importante: il
+lavoro non è ancora finito. L'inserimento nel ramo principale porta con se
+nuove sfide.
+
+Cominciamo con il dire che ora la visibilità della vostra modifica è
+ulteriormente cresciuta. Ci potrebbe portare ad una nuova fase di
+commenti dagli sviluppatori che non erano ancora a conoscenza della vostra
+patch. Ignorarli potrebbe essere allettante dato che non ci sono più
+dubbi sull'integrazione della modifica. Resistete a tale tentazione, dovete
+mantenervi disponibili agli sviluppatori che hanno domande o suggerimenti
+per voi.
+
+Ancora più importante: l'inclusione nel ramo principale mette il vostro
+codice nelle mani di un gruppo di *tester* molto più esteso. Anche se avete
+contribuito ad un driver per un hardware che non è ancora disponibile, sarete
+sorpresi da quante persone inseriranno il vostro codice nei loro kernel.
+E, ovviamente, dove ci sono *tester*, ci saranno anche dei rapporti su
+eventuali bachi.
+
+La peggior specie di rapporti sono quelli che indicano delle regressioni.
+Se la vostra modifica causa una regressione, avrete un gran numero di
+occhi puntati su di voi; la regressione deve essere sistemata il prima
+possibile. Se non vorrete o non sarete capaci di sistemarla (e nessuno
+lo farà per voi), la vostra modifica sarà quasi certamente rimossa durante
+la fase di stabilizzazione. Oltre alla perdita di tutto il lavoro svolto
+per far si che la vostra modifica fosse inserita nel ramo principale,
+l'avere una modifica rimossa a causa del fallimento nel sistemare una
+regressione, potrebbe rendere più difficile per voi far accettare
+il vostro lavoro in futuro.
+
+Dopo che ogni regressione è stata affrontata, ci potrebbero essere altri
+bachi ordinari da "sconfiggere". Il periodo di stabilizzazione è la
+vostra migliore opportunità per sistemare questi bachi e assicurarvi che
+il debutto del vostro codice nel ramo principale del kernel sia il più solido
+possibile. Quindi, per favore, rispondete ai rapporti sui bachi e ponete
+rimedio, se possibile, a tutti i problemi. È a questo che serve il periodo
+di stabilizzazione; potete iniziare creando nuove fantastiche modifiche
+una volta che ogni problema con le vecchie sia stato risolto.
+
+Non dimenticate che esistono altre pietre miliari che possono generare
+rapporti sui bachi: il successivo rilascio stabile, quando una distribuzione
+importante usa una versione del kernel nel quale è presente la vostra
+modifica, eccetera. Il continuare a rispondere a questi rapporti è fonte di
+orgoglio per il vostro lavoro. Se questa non è una sufficiente motivazione,
+allora, è anche consigliabile considera che la comunità di sviluppo ricorda
+gli sviluppatori che hanno perso interesse per il loro codice una volta
+integrato. La prossima volta che pubblicherete una patch, la comunità
+la valuterà anche sulla base del fatto che non sarete disponibili a
+prendervene cura anche nel futuro.
+
+
+Altre cose che posso accadere
+=============================
+
+Un giorno, potreste aprire la vostra email e vedere che qualcuno vi ha
+inviato una patch per il vostro codice. Questo, dopo tutto, è uno dei
+vantaggi di avere il vostro codice "là fuori". Se siete d'accordo con
+la modifica, potrete anche inoltrarla ad un manutentore di sottosistema
+(assicuratevi di includere la riga "From:" cosicché l'attribuzione sia
+corretta, e aggiungete una vostra firma "Signed-off-by"), oppure inviate
+un "Acked-by:" e lasciate che l'autore originale la invii.
+
+Se non siete d'accordo con la patch, inviate una risposta educata
+spiegando il perché. Se possibile, dite all'autore quali cambiamenti
+servirebbero per rendere la patch accettabile da voi. C'è una certa
+riluttanza nell'inserire modifiche con un conflitto fra autore
+e manutentore del codice, ma solo fino ad un certo punto. Se siete visti
+come qualcuno che blocca un buon lavoro senza motivo, quelle patch vi
+passeranno oltre e andranno nel ramo principale in ogni caso. Nel kernel
+Linux, nessuno ha potere di veto assoluto su alcun codice. Eccezione
+fatta per Linus, forse.
+
+In rarissime occasioni, potreste vedere qualcosa di completamente diverso:
+un altro sviluppatore che pubblica una soluzione differente al vostro
+problema. A questo punto, c'è una buona probabilità che una delle due
+modifiche non verrà integrata, e il "c'ero prima io" non è considerato
+un argomento tecnico rilevante. Se la modifica di qualcun'altro rimpiazza
+la vostra ed entra nel ramo principale, esiste un unico modo di reagire:
+siate contenti che il vostro problema sia stato risolto e andate avanti con
+il vostro lavoro. L'avere un vostro lavoro spintonato da parte in questo
+modo può essere avvilente e scoraggiante, ma la comunità ricorderà come
+avrete reagito anche dopo che avrà dimenticato quale fu la modifica accettata.

+
+Argomenti avanzati
+==================
+
+A questo punto, si spera, dovreste avere un'idea su come funziona il processo
+di sviluppo. Ma rimane comunque molto da imparare! Questo capitolo copre
+alcuni argomenti che potrebbero essere utili per gli sviluppatori che stanno
+per diventare parte integrante del processo di sviluppo del kernel.
+
+Gestire le modifiche con git
+-----------------------------
+
+L'uso di un sistema distribuito per il controllo delle versioni del kernel
+ebbe iniziò nel 2002 quando Linux iniziò a provare il programma proprietario
+BitKeeper. Nonostante l'uso di BitKeeper fosse opinabile, di certo il suo
+approccio alla gestione dei sorgenti non lo era. Un sistema distribuito per
+il controllo delle versioni accelerò immediatamente lo sviluppo del kernel.
+Oggigiorno, ci sono diverse alternative libere a BitKeeper. Per il meglio o il
+peggio, il progetto del kernel ha deciso di usare git per gestire i sorgenti.
+
+Gestire le modifiche con git può rendere la vita dello sviluppatore molto
+più facile, specialmente quando il volume delle modifiche cresce.
+Git ha anche i suoi lati taglienti che possono essere pericolosi; è uno
+strumento giovane e potente che è ancora in fase di civilizzazione da parte
+dei suoi sviluppatori. Questo documento non ha lo scopo di insegnare l'uso
+di git ai suoi lettori; ci sarebbe materiale a sufficienza per un lungo
+documento al riguardo. Invece, qui ci concentriamo in particolare su come
+git è parte del processo di sviluppo del kernel. Gli sviluppatori che
+desiderassero diventare agili con git troveranno più informazioni ai
+seguenti indirizzi:
+
+ http://git-scm.com/
+
+ http://www.kernel.org/pub/software/scm/git/docs/user-manual.html
+
+e su varie guide che potrete trovare su internet.
+
+La prima cosa da fare prima di usarlo per produrre patch che saranno
+disponibili ad altri, è quella di leggere i siti qui sopra e di acquisire una
+base solida su come funziona git. Uno sviluppatore che sappia usare git
+dovrebbe essere capace di ottenere una copia del repositorio principale,
+esplorare la storia della revisione, registrare le modifiche, usare i rami,
+eccetera. Una certa comprensione degli strumenti git per riscrivere la storia
+(come ``rebase``) è altrettanto utile. Git ha i propri concetti e la propria
+terminologia; un nuovo utente dovrebbe conoscere *refs*, *remote branch*,
+*index*, *fast-forward merge*, *push* e *pull*, *detached head*, eccetera.
+Il tutto potrebbe essere un po' intimidatorio visto da fuori, ma con un po'
+di studio i concetti non saranno così difficili da capire.
+
+Utilizzare git per produrre patch da sottomettere via email può essere
+un buon esercizio da fare mentre si sta prendendo confidenza con lo strumento.
+
+Quando sarete in grado di creare rami git che siano guardabili da altri,
+vi servirà, ovviamente, un server dal quale sia possibile attingere le vostre
+modifiche. Se avete un server accessibile da Internet, configurarlo per
+eseguire git-daemon è relativamente semplice . Altrimenti, iniziano a
+svilupparsi piattaforme che offrono spazi pubblici, e gratuiti (Github,
+per esempio). Gli sviluppatori permanenti possono ottenere un account
+su kernel.org, ma non è proprio facile da ottenere; per maggiori informazioni
+consultate la pagina web http://kernel.org/faq/.
+
+In git è normale avere a che fare con tanti rami. Ogni linea di sviluppo
+può essere separata in "rami per argomenti" e gestiti indipendentemente.
+In git i rami sono facilissimi, per cui non c'è motivo per non usarli
+in libertà. In ogni caso, non dovreste sviluppare su alcun ramo dal
+quale altri potrebbero attingere. I rami disponibili pubblicamente dovrebbero
+essere creati con attenzione; integrate patch dai rami di sviluppo
+solo quando sono complete e pronte ad essere consegnate - non prima.
+
+Git offre alcuni strumenti che vi permettono di riscrivere la storia del
+vostro sviluppo. Una modifica errata (diciamo, una che rompe la bisezione,
+oppure che ha un qualche tipo di baco evidente) può essere corretta sul posto
+o fatta sparire completamente dalla storia. Una serie di patch può essere
+riscritta come se fosse stata scritta in cima al ramo principale di oggi,
+anche se ci avete lavorato per mesi. Le modifiche possono essere spostate
+in modo trasparente da un ramo ad un altro. E così via. Un uso giudizioso
+di git per revisionare la storia può aiutare nella creazione di una serie
+di patch pulite e con meno problemi.
+
+Un uso eccessivo può portare ad altri tipi di problemi, tuttavia, oltre
+alla semplice ossessione per la creazione di una storia del progetto che sia
+perfetta. Riscrivere la storia riscriverà le patch contenute in quella
+storia, trasformando un kernel verificato (si spera) in uno da verificare.
+Ma, oltre a questo, gli sviluppatori non possono collaborare se non condividono
+la stessa vista sulla storia del progetto; se riscrivete la storia dalla quale
+altri sviluppatori hanno attinto per i loro repositori, renderete la loro vita
+molto più difficile. Quindi tenete conto di questa semplice regola generale:
+la storia che avete esposto ad altri, generalmente, dovrebbe essere vista come
+immutabile.
+
+Dunque, una volta che il vostro insieme di patch è stato reso disponibile
+pubblicamente non dovrebbe essere più sovrascritto. Git tenterà di imporre
+questa regola, e si rifiuterà di pubblicare nuove patch che non risultino
+essere dirette discendenti di quelle pubblicate in precedenza (in altre parole,
+patch che non condividono la stessa storia). È possibile ignorare questo
+controllo, e ci saranno momenti in cui sarà davvero necessario riscrivere
+un ramo già pubblicato. Un esempio è linux-next dove le patch vengono
+spostate da un ramo all'altro al fine di evitare conflitti. Ma questo tipo
+d'azione dovrebbe essere un'eccezione. Questo è uno dei motivi per cui lo
+sviluppo dovrebbe avvenire in rami privati (che possono essere sovrascritti
+quando lo si ritiene necessario) e reso pubblico solo quando è in uno stato
+avanzato.
+
+Man mano che il ramo principale (o altri rami su cui avete basato le
+modifiche) avanza, diventa allettante l'idea di integrare tutte le patch
+per rimanere sempre aggiornati. Per un ramo privato, il *rebase* può essere
+un modo semplice per rimanere aggiornati, ma questa non è un'opzione nel
+momento in cui il vostro ramo è stato esposto al mondo intero.
+*Merge* occasionali possono essere considerati di buon senso, ma quando
+diventano troppo frequenti confondono inutilmente la storia. La tecnica
+suggerita in questi casi è quella di fare *merge* raramente, e più in generale
+solo nei momenti di rilascio (per esempio gli -rc del ramo principale).
+Se siete nervosi circa alcune patch in particolare, potete sempre fare
+dei *merge* di test in un ramo privato. In queste situazioni git "rerere"
+può essere utile; questo strumento si ricorda come i conflitti di *merge*
+furono risolti in passato cosicché non dovrete fare lo stesso lavoro due volte.
+
+Una delle lamentele più grosse e ricorrenti sull'uso di strumenti come git
+è il grande movimento di patch da un repositorio all'altro che rende
+facile l'integrazione nel ramo principale di modifiche mediocri, il tutto
+sotto il naso dei revisori. Gli sviluppatori del kernel tendono ad essere
+scontenti quando vedono succedere queste cose; preparare un ramo git con
+patch che non hanno ricevuto alcuna revisione o completamente avulse, potrebbe
+influire sulla vostra capacita di proporre, in futuro, l'integrazione dei
+vostri rami. Citando Linus
+
+::
+
+ Potete inviarmi le vostre patch, ma per far si che io integri una
+ vostra modifica da git, devo sapere che voi sappiate cosa state
+ facendo, e ho bisogno di fidarmi *senza* dover passare tutte
+ le modifiche manualmente una per una.
+
+(http://lwn.net/Articles/224135/).
+
+Per evitare queste situazioni, assicuratevi che tutte le patch in un ramo
+siano strettamente correlate al tema delle modifiche; un ramo "driver fixes"
+non dovrebbe fare modifiche al codice principale per la gestione della memoria.
+E, più importante ancora, non usate un repositorio git per tentare di
+evitare il processo di revisione. Pubblicate un sommario di quello che il
+vostro ramo contiene sulle liste di discussione più opportune, e , quando
+sarà il momento, richiedete che il vostro ramo venga integrato in linux-next.
+
+Se e quando altri inizieranno ad inviarvi patch per essere incluse nel
+vostro repositorio, non dovete dimenticare di revisionarle. Inoltre
+assicuratevi di mantenerne le informazioni di paternità; al riguardo git "am"
+fa del suo meglio, ma potreste dover aggiungere una riga "From:" alla patch
+nel caso in cui sia arrivata per vie traverse.
+
+Quando richiedete l'integrazione, siate certi di fornire tutte le informazioni:
+dov'è il vostro repositorio, quale ramo integrare, e quali cambiamenti si
+otterranno dall'integrazione. Il comando git request-pull può essere d'aiuto;
+preparerà una richiesta nel modo in cui gli altri sviluppatori se l'aspettano,
+e verificherà che vi siate ricordati di pubblicare quelle patch su un
+server pubblico.
+
+Revisionare le patch
+--------------------
+
+Alcuni lettori potrebbero avere obiezioni sulla presenza di questa sezione
+negli "argomenti avanzati" sulla base che anche gli sviluppatori principianti
+dovrebbero revisionare le patch. É certamente vero che non c'è modo
+migliore di imparare come programmare per il kernel che guardare il codice
+pubblicato dagli altri. In aggiunta, i revisori sono sempre troppo pochi;
+guardando il codice potete apportare un significativo contributo all'intero
+processo.
+
+Revisionare il codice potrebbe risultare intimidatorio, specialmente per i
+nuovi arrivati che potrebbero sentirsi un po' nervosi nel questionare
+il codice - in pubblico - pubblicato da sviluppatori più esperti. Perfino
+il codice scritto dagli sviluppatori più esperti può essere migliorato.
+Forse il suggerimento migliore per i revisori (tutti) è questo: formulate
+i commenti come domande e non come critiche. Chiedere "Come viene rilasciato
+il *lock* in questo percorso?" funziona sempre molto meglio che
+"qui la sincronizzazione è sbagliata".
+
+Diversi sviluppatori revisioneranno il codice con diversi punti di vista.
+Alcuni potrebbero concentrarsi principalmente sullo stile del codice e se
+alcune linee hanno degli spazio bianchi di troppo. Altri si chiederanno
+se accettare una modifica interamente è una cosa positiva per il kernel
+o no. E altri ancora si focalizzeranno sui problemi di sincronizzazione,
+l'uso eccessivo di *stack*, problemi di sicurezza, duplicazione del codice
+in altri contesti, documentazione, effetti negativi sulle prestazioni, cambi
+all'ABI dello spazio utente, eccetera. Qualunque tipo di revisione è ben
+accetta e di valore, se porta ad avere un codice migliore nel kernel.

+Per maggiori informazioni
+=========================
+
+Esistono numerose fonti di informazioni sullo sviluppo del kernel Linux
+e argomenti correlati. Primo tra questi sarà sempre la cartella Documentation
+che si trova nei sorgenti kernel.
+
+Il file :ref:`process/howto.rst <it_process_howto>` è un punto di partenza
+importante; :ref:`process/submitting-patches.rst <it_submittingpatches>` e
+:ref:`process/submitting-drivers.rst <it_submittingdrivers>` sono
+anch'essi qualcosa che tutti gli sviluppatori del kernel dovrebbero leggere.
+Molte API interne al kernel sono documentate utilizzando il meccanismo
+kerneldoc; "make htmldocs" o "make pdfdocs" possono essere usati per generare
+quei documenti in HTML o PDF (sebbene le versioni di TeX di alcune
+distribuzioni hanno dei limiti interni e fallisce nel processare
+appropriatamente i documenti).
+
+Diversi siti web approfondiscono lo sviluppo del kernel ad ogni livello
+di dettaglio. Il vostro autore vorrebbe umilmente suggerirvi
+http://lwn.net/ come fonte; usando l'indice 'kernel' su LWN troverete
+molti argomenti specifici sul kernel:
+
+ http://lwn.net/Kernel/Index/
+
+Oltre a ciò, una risorsa valida per gli sviluppatori kernel è:
+
+ http://kernelnewbies.org/
+
+E, ovviamente, una fonte da non dimenticare è http://kernel.org/, il luogo
+definitivo per le informazioni sui rilasci del kernel.
+
+Ci sono numerosi libri sullo sviluppo del kernel:
+
+ Linux Device Drivers, 3rd Edition (Jonathan Corbet, Alessandro
+ Rubini, and Greg Kroah-Hartman). In linea all'indirizzo
+ http://lwn.net/Kernel/LDD3/.
+
+ Linux Kernel Development (Robert Love).
+
+ Understanding the Linux Kernel (Daniel Bovet and Marco Cesati).
+
+Tutti questi libri soffrono di un errore comune: tendono a risultare in un
+certo senso obsoleti dal momento che si trovano in libreria da diverso
+tempo. Comunque contengono informazioni abbastanza buone.
+
+La documentazione per git la troverete su:
+
+ http://www.kernel.org/pub/software/scm/git/docs/
+
+ http://www.kernel.org/pub/software/scm/git/docs/user-manual.html
+
+
+
+Conclusioni
+===========
+
+Congratulazioni a chiunque ce l'abbia fatta a terminare questo documento di
+lungo-respiro. Si spera che abbia fornito un'utile comprensione d'insieme
+di come il kernel Linux viene sviluppato e di come potete partecipare a
+tale processo.
+
+Infine, quello che conta è partecipare. Qualsiasi progetto software
+open-source non è altro che la somma di quello che i suoi contributori
+mettono al suo interno. Il kernel Linux è cresciuto velocemente e bene
+perché ha ricevuto il supporto di un impressionante gruppo di sviluppatori,
+ognuno dei quali sta lavorando per renderlo migliore. Il kernel è un esempio
+importante di cosa può essere fatto quando migliaia di persone lavorano
+insieme verso un obiettivo comune.
+
+Il kernel può sempre beneficiare di una larga base di sviluppatori, tuttavia,
+c'è sempre molto lavoro da fare. Ma, cosa non meno importante, molti degli
+altri partecipanti all'ecosistema Linux possono trarre beneficio attraverso
+il contributo al kernel. Inserire codice nel ramo principale è la chiave
+per arrivare ad una qualità del codice più alta, bassa manutenzione e
+bassi prezzi di distribuzione, alti livelli d'influenza sulla direzione
+dello sviluppo del kernel, e molto altro. È una situazione nella quale
+tutti coloro che sono coinvolti vincono. Mollate il vostro editor e
+raggiungeteci; sarete più che benvenuti.

+
+Aggiungere una nuova chiamata di sistema
+========================================
+
+Questo documento descrive quello che è necessario sapere per aggiungere
+nuove chiamate di sistema al kernel Linux; questo è da considerarsi come
+un'aggiunta ai soliti consigli su come proporre nuove modifiche
+:ref:`Documentation/translations/it_IT/process/submitting-patches.rst <it_submittingpatches>`.
+
+
+Alternative alle chiamate di sistema
+------------------------------------
+
+La prima considerazione da fare quando si aggiunge una nuova chiamata di
+sistema è quella di valutare le alternative. Nonostante le chiamate di sistema
+siano il punto di interazione fra spazio utente e kernel più tradizionale ed
+ovvio, esistono altre possibilità - scegliete quella che meglio si adatta alle
+vostra interfaccia.
+
+ - Se le operazioni coinvolte possono rassomigliare a quelle di un filesystem,
+ allora potrebbe avere molto più senso la creazione di un nuovo filesystem o
+ dispositivo. Inoltre, questo rende più facile incapsulare la nuova
+ funzionalità in un modulo kernel piuttosto che essere sviluppata nel cuore
+ del kernel.
+
+ - Se la nuova funzionalità prevede operazioni dove il kernel notifica
+ lo spazio utente su un avvenimento, allora restituire un descrittore
+ di file all'oggetto corrispondente permette allo spazio utente di
+ utilizzare ``poll``/``select``/``epoll`` per ricevere quelle notifiche.
+ - Tuttavia, le operazioni che non si sposano bene con operazioni tipo
+ :manpage:`read(2)`/:manpage:`write(2)` dovrebbero essere implementate
+ come chiamate :manpage:`ioctl(2)`, il che potrebbe portare ad un'API in
+ un qualche modo opaca.
+
+ - Se dovete esporre solo delle informazioni sul sistema, un nuovo nodo in
+ sysfs (vedere ``Documentation/translations/it_IT/filesystems/sysfs.txt``) o
+ in procfs potrebbe essere sufficiente. Tuttavia, l'accesso a questi
+ meccanismi richiede che il filesystem sia montato, il che potrebbe non
+ essere sempre vero (per esempio, in ambienti come namespace/sandbox/chroot).
+ Evitate d'aggiungere nuove API in debugfs perché questo non viene
+ considerata un'interfaccia di 'produzione' verso lo spazio utente.
+ - Se l'operazione è specifica ad un particolare file o descrittore, allora
+ potrebbe essere appropriata l'aggiunta di un comando :manpage:`fcntl(2)`.
+ Tuttavia, :manpage:`fcntl(2)` è una chiamata di sistema multiplatrice che
+ nasconde una notevole complessità, quindi è ottima solo quando la nuova
+ funzione assomiglia a quelle già esistenti in :manpage:`fcntl(2)`, oppure
+ la nuova funzionalità è veramente semplice (per esempio, leggere/scrivere
+ un semplice flag associato ad un descrittore di file).
+ - Se l'operazione è specifica ad un particolare processo, allora
+ potrebbe essere appropriata l'aggiunta di un comando :manpage:`prctl(2)`.
+ Come per :manpage:`fcntl(2)`, questa chiamata di sistema è un complesso
+ multiplatore quindi è meglio usarlo per cose molto simili a quelle esistenti
+ nel comando ``prctl`` oppure per leggere/scrivere un semplice flag relativo
+ al processo.
+
+
+Progettare l'API: pianificare le estensioni
+-------------------------------------------
+
+Una nuova chiamata di sistema diventerà parte dell'API del kernel, e
+dev'essere supportata per un periodo indefinito. Per questo, è davvero
+un'ottima idea quella di discutere apertamente l'interfaccia sulla lista
+di discussione del kernel, ed è altrettanto importante pianificarne eventuali
+estensioni future.
+
+(Nella tabella delle chiamate di sistema sono disseminati esempi dove questo
+non fu fatto, assieme ai corrispondenti aggiornamenti -
+``eventfd``/``eventfd2``, ``dup2``/``dup3``, ``inotify_init``/``inotify_init1``,
+``pipe``/``pipe2``, ``renameat``/``renameat2`` --quindi imparate dalla storia
+del kernel e pianificate le estensioni fin dall'inizio)
+
+Per semplici chiamate di sistema che accettano solo un paio di argomenti,
+il modo migliore di permettere l'estensibilità è quello di includere un
+argomento *flags* alla chiamata di sistema. Per assicurarsi che i programmi
+dello spazio utente possano usare in sicurezza *flags* con diverse versioni
+del kernel, verificate se *flags* contiene un qualsiasi valore sconosciuto,
+in qual caso rifiutate la chiamata di sistema (con ``EINVAL``)::
+
+ if (flags & ~(THING_FLAG1 | THING_FLAG2 | THING_FLAG3))
+ return -EINVAL;
+
+(Se *flags* non viene ancora utilizzato, verificate che l'argomento sia zero)
+
+Per chiamate di sistema più sofisticate che coinvolgono un numero più grande di
+argomenti, il modo migliore è quello di incapsularne la maggior parte in una
+struttura dati che verrà passata per puntatore. Questa struttura potrà
+funzionare con future estensioni includendo un campo *size*::
+
+ struct xyzzy_params {
+ u32 size; /* userspace sets p->size = sizeof(struct xyzzy_params) */
+ u32 param_1;
+ u64 param_2;
+ u64 param_3;
+ };
+
+Fintanto che un qualsiasi campo nuovo, diciamo ``param_4``, è progettato per
+offrire il comportamento precedente quando vale zero, allora questo permetterà
+di gestire un conflitto di versione in entrambe le direzioni:
+
+ - un vecchio kernel può gestire l'accesso di una versione moderna di un
+ programma in spazio utente verificando che la memoria oltre la dimensione
+ della struttura dati attesa sia zero (in pratica verificare che
+ ``param_4 == 0``).
+ - un nuovo kernel può gestire l'accesso di una versione vecchia di un
+ programma in spazio utente estendendo la struttura dati con zeri (in pratica
+ ``param_4 = 0``).
+
+Vedere :manpage:`perf_event_open(2)` e la funzione ``perf_copy_attr()`` (in
+``kernel/events/core.c``) per un esempio pratico di questo approccio.
+
+
+Progettare l'API: altre considerazioni
+--------------------------------------
+
+Se la vostra nuova chiamata di sistema permette allo spazio utente di fare
+riferimento ad un oggetto del kernel, allora questa dovrebbe usare un
+descrittore di file per accesso all'oggetto - non inventatevi nuovi tipi di
+accesso da spazio utente quando il kernel ha già dei meccanismi e una semantica
+ben definita per utilizzare i descrittori di file.
+
+Se la vostra nuova chiamata di sistema :manpage:`xyzzy(2)` ritorna un nuovo
+descrittore di file, allora l'argomento *flags* dovrebbe includere un valore
+equivalente a ``O_CLOEXEC`` per i nuovi descrittori. Questo rende possibile,
+nello spazio utente, la chiusura della finestra temporale fra le chiamate a
+``xyzzy()`` e ``fcntl(fd, F_SETFD, FD_CLOEXEC)``, dove un inaspettato
+``fork()`` o ``execve()`` potrebbe trasferire il descrittore al programma
+eseguito (Comunque, resistete alla tentazione di riutilizzare il valore di
+``O_CLOEXEC`` dato che è specifico dell'architettura e fa parte di una
+enumerazione di flag ``O_*`` che è abbastanza ricca).
+
+Se la vostra nuova chiamata di sistema ritorna un nuovo descrittore di file,
+dovreste considerare che significato avrà l'uso delle chiamate di sistema
+della famiglia di :manpage:`poll(2)`. Rendere un descrittore di file pronto
+per la lettura o la scrittura è il tipico modo del kernel per notificare lo
+spazio utente circa un evento associato all'oggetto del kernel.
+
+Se la vostra nuova chiamata di sistema :manpage:`xyzzy(2)` ha un argomento
+che è il percorso ad un file::
+
+ int sys_xyzzy(const char __user *path, ..., unsigned int flags);
+
+dovreste anche considerare se non sia più appropriata una versione
+:manpage:`xyzzyat(2)`::
+
+ int sys_xyzzyat(int dfd, const char __user *path, ..., unsigned int flags);
+
+Questo permette più flessibilità su come lo spazio utente specificherà il file
+in questione; in particolare, permette allo spazio utente di richiedere la
+funzionalità su un descrittore di file già aperto utilizzando il *flag*
+``AT_EMPTY_PATH``, in pratica otterremmo gratuitamente l'operazione
+:manpage:`fxyzzy(3)`::
+
+ - xyzzyat(AT_FDCWD, path, ..., 0) is equivalent to xyzzy(path,...)
+ - xyzzyat(fd, "", ..., AT_EMPTY_PATH) is equivalent to fxyzzy(fd, ...)
+
+(Per maggiori dettagli sulla logica delle chiamate \*at(), leggete la pagina
+man :manpage:`openat(2)`; per un esempio di AT_EMPTY_PATH, leggere la pagina
+man :manpage:`fstatat(2)`).
+
+Se la vostra nuova chiamata di sistema :manpage:`xyzzy(2)` prevede un parametro
+per descrivere uno scostamento all'interno di un file, usate ``loff_t`` come
+tipo cosicché scostamenti a 64-bit potranno essere supportati anche su
+architetture a 32-bit.
+
+Se la vostra nuova chiamata di sistema :manpage:`xyzzy(2)` prevede l'uso di
+funzioni riservate, allora dev'essere gestita da un opportuno bit di privilegio
+(verificato con una chiamata a ``capable()``), come descritto nella pagina man
+:manpage:`capabilities(7)`. Scegliete un bit di privilegio già esistente per
+gestire la funzionalità associata, ma evitate la combinazione di diverse
+funzionalità vagamente collegate dietro lo stesso bit, in quanto va contro il
+principio di *capabilities* di separare i poteri di root. In particolare,
+evitate di aggiungere nuovi usi al fin-troppo-generico privilegio
+``CAP_SYS_ADMIN``.
+
+Se la vostra nuova chiamata di sistema :manpage:`xyzzy(2)` manipola altri
+processi oltre a quello chiamato, allora dovrebbe essere limitata (usando
+la chiamata ``ptrace_may_access()``) di modo che solo un processo chiamante
+con gli stessi permessi del processo in oggetto, o con i necessari privilegi,
+possa manipolarlo.
+
+Infine, state attenti che in alcune architetture non-x86 la vita delle chiamate
+di sistema con argomenti a 64-bit viene semplificata se questi argomenti
+ricadono in posizioni dispari (pratica, i parametri 1, 3, 5); questo permette
+l'uso di coppie contigue di registri a 32-bit. (Questo non conta se gli
+argomenti sono parte di una struttura dati che viene passata per puntatore).
+
+
+Proporre l'API
+--------------
+
+Al fine di rendere le nuove chiamate di sistema di facile revisione, è meglio
+che dividiate le modifiche i pezzi separati. Questi dovrebbero includere
+almeno le seguenti voci in *commit* distinti (ognuno dei quali sarà descritto
+più avanti):
+
+ - l'essenza dell'implementazione della chiamata di sistema, con i prototipi,
+ i numeri generici, le modifiche al Kconfig e l'implementazione *stub* di
+ ripiego.
+ - preparare la nuova chiamata di sistema per un'architettura specifica,
+ solitamente x86 (ovvero tutti: x86_64, x86_32 e x32).
+ - un programma di auto-verifica da mettere in ``tools/testing/selftests/``
+ che mostri l'uso della chiamata di sistema.
+ - una bozza di pagina man per la nuova chiamata di sistema. Può essere
+ scritta nell'email di presentazione, oppure come modifica vera e propria
+ al repositorio delle pagine man.
+
+Le proposte di nuove chiamate di sistema, come ogni altro modifica all'API del
+kernel, deve essere sottomessa alla lista di discussione
+linux-api@vger.kernel.org.
+
+
+Implementazione di chiamate di sistema generiche
+------------------------------------------------
+
+Il principale punto d'accesso alla vostra nuova chiamata di sistema
+:manpage:`xyzzy(2)` verrà chiamato ``sys_xyzzy()``; ma, piuttosto che in modo
+esplicito, lo aggiungerete tramite la macro ``SYSCALL_DEFINEn``. La 'n'
+indica il numero di argomenti della chiamata di sistema; la macro ha come
+argomento il nome della chiamata di sistema, seguito dalle coppie (tipo, nome)
+per definire i suoi parametri. L'uso di questa macro permette di avere
+i metadati della nuova chiamata di sistema disponibili anche per altri
+strumenti.
+
+Il nuovo punto d'accesso necessita anche del suo prototipo di funzione in
+``include/linux/syscalls.h``, marcato come asmlinkage di modo da abbinargli
+il modo in cui quelle chiamate di sistema verranno invocate::
+
+ asmlinkage long sys_xyzzy(...);
+
+Alcune architetture (per esempio x86) hanno le loro specifiche tabelle di
+chiamate di sistema (syscall), ma molte altre architetture condividono una
+tabella comune di syscall. Aggiungete alla lista generica la vostra nuova
+chiamata di sistema aggiungendo un nuovo elemento alla lista in
+``include/uapi/asm-generic/unistd.h``::
+
+ #define __NR_xyzzy 292
+ __SYSCALL(__NR_xyzzy, sys_xyzzy)
+
+Aggiornate anche il contatore __NR_syscalls di modo che sia coerente con
+l'aggiunta della nuove chiamate di sistema; va notato che se più di una nuova
+chiamata di sistema viene aggiunga nella stessa finestra di sviluppo, il numero
+della vostra nuova syscall potrebbe essere aggiustato al fine di risolvere i
+conflitti.
+
+Il file ``kernel/sys_ni.c`` fornisce le implementazioni *stub* di ripiego che
+ritornano ``-ENOSYS``. Aggiungete la vostra nuova chiamata di sistema anche
+qui::
+
+ COND_SYSCALL(xyzzy);
+
+La vostra nuova funzionalità del kernel, e la chiamata di sistema che la
+controlla, dovrebbero essere opzionali. Quindi, aggiungete un'opzione
+``CONFIG`` (solitamente in ``init/Kconfig``). Come al solito per le nuove
+opzioni ``CONFIG``:
+
+ - Includete una descrizione della nuova funzionalità e della chiamata di
+ sistema che la controlla.
+ - Rendete l'opzione dipendente da EXPERT se dev'essere nascosta agli utenti
+ normali.
+ - Nel Makefile, rendere tutti i nuovi file sorgenti, che implementano la
+ nuova funzionalità, dipendenti dall'opzione CONFIG (per esempio
+ ``obj-$(CONFIG_XYZZY_SYSCALL) += xyzzy.o``).
+ - Controllate due volte che sia possibile generare il kernel con la nuova
+ opzione CONFIG disabilitata.
+
+Per riassumere, vi serve un *commit* che includa:
+
+ - un'opzione ``CONFIG``per la nuova funzione, normalmente in ``init/Kconfig``
+ - ``SYSCALL_DEFINEn(xyzzy, ...)`` per il punto d'accesso
+ - il corrispondente prototipo in ``include/linux/syscalls.h``
+ - un elemento nella tabella generica in ``include/uapi/asm-generic/unistd.h``
+ - *stub* di ripiego in ``kernel/sys_ni.c``
+
+
+Implementazione delle chiamate di sistema x86
+---------------------------------------------
+
+Per collegare la vostra nuova chiamate di sistema alle piattaforme x86,
+dovete aggiornate la tabella principale di syscall. Assumendo che la vostra
+nuova chiamata di sistema non sia particolarmente speciale (vedere sotto),
+dovete aggiungere un elemento *common* (per x86_64 e x32) in
+arch/x86/entry/syscalls/syscall_64.tbl::
+
+ 333 common xyzzy sys_xyzzy
+
+e un elemento per *i386* ``arch/x86/entry/syscalls/syscall_32.tbl``::
+
+ 380 i386 xyzzy sys_xyzzy
+
+Ancora una volta, questi numeri potrebbero essere cambiati se generano
+conflitti durante la finestra di integrazione.
+
+
+Chiamate di sistema compatibili (generico)
+------------------------------------------
+
+Per molte chiamate di sistema, la stessa implementazione a 64-bit può essere
+invocata anche quando il programma in spazio utente è a 32-bit; anche se la
+chiamata di sistema include esplicitamente un puntatore, questo viene gestito
+in modo trasparente.
+
+Tuttavia, ci sono un paio di situazione dove diventa necessario avere un
+livello di gestione della compatibilità per risolvere le differenze di
+dimensioni fra 32-bit e 64-bit.
+
+Il primo caso è quando un kernel a 64-bit supporta anche programmi in spazio
+utente a 32-bit, perciò dovrà ispezionare aree della memoria (``__user``) che
+potrebbero contenere valori a 32-bit o a 64-bit. In particolar modo, questo
+è necessario quando un argomento di una chiamata di sistema è:
+
+ - un puntatore ad un puntatore
+ - un puntatore ad una struttura dati contenente a sua volta un puntatore
+ ( ad esempio ``struct iovec __user *``)
+ - un puntatore ad un tipo intero di dimensione variabile (``time_t``,
+ ``off_t``, ``long``, ...)
+ - un puntatore ad una struttura dati contenente un tipo intero di dimensione
+ variabile.
+
+Il secondo caso che richiede un livello di gestione della compatibilità è
+quando uno degli argomenti di una chiamata a sistema è esplicitamente un tipo
+a 64-bit anche su architetture a 32-bit, per esempio ``loff_t`` o ``__u64``.
+In questo caso, un valore che arriva ad un kernel a 64-bit da un'applicazione
+a 32-bit verrà diviso in due valori a 32-bit che dovranno essere riassemblati
+in questo livello di compatibilità.
+
+(Da notare che non serve questo livello di compatibilità per argomenti che
+sono puntatori ad un tipo esplicitamente a 64-bit; per esempio, in
+:manpage:`splice(2)` l'argomento di tipo ``loff_t __user *`` non necessita
+di una chiamata di sistema ``compat_``)
+
+La versione compatibile della nostra chiamata di sistema si chiamerà
+``compat_sys_xyzzy()``, e viene aggiunta utilizzando la macro
+``COMPAT_SYSCALL_DEFINEn()`` (simile a SYSCALL_DEFINEn). Questa versione
+dell'implementazione è parte del kernel a 64-bit ma accetta parametri a 32-bit
+che trasformerà secondo le necessità (tipicamente, la versione
+``compat_sys_`` converte questi valori nello loro corrispondente a 64-bit e
+può chiamare la versione ``sys_`` oppure invocare una funzione che implementa
+le parti comuni).
+
+Il punto d'accesso *compat* deve avere il corrispondente prototipo di funzione
+in ``include/linux/compat.h``, marcato come asmlinkage di modo da abbinargli
+il modo in cui quelle chiamate di sistema verranno invocate::
+
+ asmlinkage long compat_sys_xyzzy(...);
+
+Se la chiamata di sistema prevede una struttura dati organizzata in modo
+diverso per sistemi a 32-bit e per quelli a 64-bit, diciamo
+``struct xyzzy_args``, allora il file d'intestazione
+``then the include/linux/compat.h`` deve includere la sua versione
+*compatibile* (``struct compat_xyzzy_args``); ogni variabile con
+dimensione variabile deve avere il proprio tipo ``compat_`` corrispondente
+a quello in ``struct xyzzy_args``. La funzione ``compat_sys_xyzzy()``
+può usare la struttura ``compat_`` per analizzare gli argomenti ricevuti
+da una chiamata a 32-bit.
+
+Per esempio, se avete i seguenti campi::
+
+ struct xyzzy_args {
+ const char __user *ptr;
+ __kernel_long_t varying_val;
+ u64 fixed_val;
+ /* ... */
+ };
+
+nella struttura ``struct xyzzy_args``, allora la struttura
+``struct compat_xyzzy_args`` dovrebbe avere::
+
+ struct compat_xyzzy_args {
+ compat_uptr_t ptr;
+ compat_long_t varying_val;
+ u64 fixed_val;
+ /* ... */
+ };
+
+La lista generica delle chiamate di sistema ha bisogno di essere
+aggiustata al fine di permettere l'uso della versione *compatibile*;
+la voce in ``include/uapi/asm-generic/unistd.h`` dovrebbero usare
+``__SC_COMP`` piuttosto di ``__SYSCALL``::
+
+ #define __NR_xyzzy 292
+ __SC_COMP(__NR_xyzzy, sys_xyzzy, compat_sys_xyzzy)
+
+Riassumendo, vi serve:
+
+ - un ``COMPAT_SYSCALL_DEFINEn(xyzzy, ...)`` per il punto d'accesso
+ *compatibile*
+ - un prototipo in ``include/linux/compat.h``
+ - (se necessario) una struttura di compatibilità a 32-bit in
+ ``include/linux/compat.h``
+ - una voce ``__SC_COMP``, e non ``__SYSCALL``, in
+ ``include/uapi/asm-generic/unistd.h``
+
+Compatibilità delle chiamate di sistema (x86)
+---------------------------------------------
+
+Per collegare una chiamata di sistema, su un'architettura x86, con la sua
+versione *compatibile*, è necessario aggiustare la voce nella tabella
+delle syscall.
+
+Per prima cosa, la voce in ``arch/x86/entry/syscalls/syscall_32.tbl`` prende
+un argomento aggiuntivo per indicare che un programma in spazio utente
+a 32-bit, eseguito su un kernel a 64-bit, dovrebbe accedere tramite il punto
+d'accesso compatibile::
+
+ 380 i386 xyzzy sys_xyzzy __ia32_compat_sys_xyzzy
+
+Secondo, dovete capire cosa dovrebbe succedere alla nuova chiamata di sistema
+per la versione dell'ABI x32. Qui C'è una scelta da fare: gli argomenti
+possono corrisponde alla versione a 64-bit o a quella a 32-bit.
+
+Se c'è un puntatore ad un puntatore, la decisione è semplice: x32 è ILP32,
+quindi gli argomenti dovrebbero corrispondere a quelli a 32-bit, e la voce in
+``arch/x86/entry/syscalls/syscall_64.tbl`` sarà divisa cosicché i programmi
+x32 eseguano la chiamata *compatibile*::
+
+ 333 64 xyzzy sys_xyzzy
+ ...
+ 555 x32 xyzzy __x32_compat_sys_xyzzy
+
+Se non ci sono puntatori, allora è preferibile riutilizzare la chiamata di
+sistema a 64-bit per l'ABI x32 (e di conseguenza la voce in
+arch/x86/entry/syscalls/syscall_64.tbl rimane immutata).
+
+In ambo i casi, dovreste verificare che i tipi usati dagli argomenti
+abbiano un'esatta corrispondenza da x32 (-mx32) al loro equivalente a
+32-bit (-m32) o 64-bit (-m64).
+
+
+Chiamate di sistema che ritornano altrove
+-----------------------------------------
+
+Nella maggior parte delle chiamate di sistema, al termine della loro
+esecuzione, i programmi in spazio utente riprendono esattamente dal punto
+in cui si erano interrotti -- quindi dall'istruzione successiva, con lo
+stesso *stack* e con la maggior parte del registri com'erano stati
+lasciati prima della chiamata di sistema, e anche con la stessa memoria
+virtuale.
+
+Tuttavia, alcune chiamata di sistema fanno le cose in modo differente.
+Potrebbero ritornare ad un punto diverso (``rt_sigreturn``) o cambiare
+la memoria in spazio utente (``fork``/``vfork``/``clone``) o perfino
+l'architettura del programma (``execve``/``execveat``).
+
+Per permettere tutto ciò, l'implementazione nel kernel di questo tipo di
+chiamate di sistema potrebbero dover salvare e ripristinare registri
+aggiuntivi nello *stack* del kernel, permettendo così un controllo completo
+su dove e come l'esecuzione dovrà continuare dopo l'esecuzione della
+chiamata di sistema.
+
+Queste saranno specifiche per ogni architettura, ma tipicamente si definiscono
+dei punti d'accesso in *assembly* per salvare/ripristinare i registri
+aggiuntivi e quindi chiamare il vero punto d'accesso per la chiamata di
+sistema.
+
+Per l'architettura x86_64, questo è implementato come un punto d'accesso
+``stub_xyzzy`` in ``arch/x86/entry/entry_64.S``, e la voce nella tabella
+di syscall (``arch/x86/entry/syscalls/syscall_64.tbl``) verrà corretta di
+conseguenza::
+
+ 333 common xyzzy stub_xyzzy
+
+L'equivalente per programmi a 32-bit eseguiti su un kernel a 64-bit viene
+normalmente chiamato ``stub32_xyzzy`` e implementato in
+``arch/x86/entry/entry_64_compat.S`` con la corrispondente voce nella tabella
+di syscall ``arch/x86/entry/syscalls/syscall_32.tbl`` corretta nel
+seguente modo::
+
+ 380 i386 xyzzy sys_xyzzy stub32_xyzzy
+
+Se una chiamata di sistema necessita di un livello di compatibilità (come
+nella sezione precedente), allora la versione ``stub32_`` deve invocare
+la versione ``compat_sys_`` piuttosto che quella nativa a 64-bit. In aggiunta,
+se l'implementazione dell'ABI x32 è diversa da quella x86_64, allora la sua
+voce nella tabella di syscall dovrà chiamare uno *stub* che invoca la versione
+``compat_sys_``,
+
+Per completezza, sarebbe carino impostare una mappatura cosicché
+*user-mode* Linux (UML) continui a funzionare -- la sua tabella di syscall
+farà riferimento a stub_xyzzy, ma UML non include l'implementazione
+in ``arch/x86/entry/entry_64.S`` (perché UML simula i registri eccetera).
+Correggerlo è semplice, basta aggiungere una #define in
+``arch/x86/um/sys_call_table_64.c``::
+
+ #define stub_xyzzy sys_xyzzy
+
+
+Altri dettagli
+--------------
+
+La maggior parte dei kernel tratta le chiamate di sistema allo stesso modo,
+ma possono esserci rare eccezioni per le quali potrebbe essere necessario
+l'aggiornamento della vostra chiamata di sistema.
+
+Il sotto-sistema di controllo (*audit subsystem*) è uno di questi casi
+speciali; esso include (per architettura) funzioni che classificano alcuni
+tipi di chiamate di sistema -- in particolare apertura dei file
+(``open``/``openat``), esecuzione dei programmi (``execve``/``exeveat``)
+oppure multiplatori di socket (``socketcall``). Se la vostra nuova chiamata
+di sistema è simile ad una di queste, allora il sistema di controllo dovrebbe
+essere aggiornato.
+
+Più in generale, se esiste una chiamata di sistema che è simile alla vostra,
+vale la pena fare una ricerca con ``grep`` su tutto il kernel per la chiamata
+di sistema esistente per verificare che non ci siano altri casi speciali.
+
+
+Verifica
+--------
+
+Una nuova chiamata di sistema dev'essere, ovviamente, provata; è utile fornire
+ai revisori un programma in spazio utente che mostri l'uso della chiamata di
+sistema. Un buon modo per combinare queste cose è quello di aggiungere un
+semplice programma di auto-verifica in una nuova cartella in
+``tools/testing/selftests/``.
+
+Per una nuova chiamata di sistema, ovviamente, non ci sarà alcuna funzione
+in libc e quindi il programma di verifica dovrà invocarla usando ``syscall()``;
+inoltre, se la nuova chiamata di sistema prevede un nuova struttura dati
+visibile in spazio utente, il file d'intestazione necessario dev'essere
+installato al fine di compilare il programma.
+
+Assicuratevi che il programma di auto-verifica possa essere eseguito
+correttamente su tutte le architetture supportate. Per esempio, verificate che
+funzioni quando viene compilato per x86_64 (-m64), x86_32 (-m32) e x32 (-mx32).
+
+Al fine di una più meticolosa ed estesa verifica della nuova funzionalità,
+dovreste considerare l'aggiunta di nuove verifica al progetto 'Linux Test',
+oppure al progetto xfstests per cambiamenti relativi al filesystem.

+
+
+Pagine man
+----------
+
+Tutte le nuove chiamate di sistema dovrebbero avere una pagina man completa,
+idealmente usando i marcatori groff, ma anche il puro testo può andare. Se
+state usando groff, è utile che includiate nella email di presentazione una
+versione già convertita in formato ASCII: semplificherà la vita dei revisori.
+
+Le pagine man dovrebbero essere in copia-conoscenza verso
+linux-man@vger.kernel.org
+Per maggiori dettagli, leggere
+https://www.kernel.org/doc/man-pages/patches.html
+
+
+Non invocate chiamate di sistema dal kernel
+-------------------------------------------
+
+Le chiamate di sistema sono, come già detto prima, punti di interazione fra
+lo spazio utente e il kernel. Perciò, le chiamate di sistema come
+``sys_xyzzy()`` o ``compat_sys_xyzzy()`` dovrebbero essere chiamate solo dallo
+spazio utente attraverso la tabella syscall, ma non da nessun altro punto nel
+kernel. Se la nuova funzionalità è utile all'interno del kernel, per esempio
+dev'essere condivisa fra una vecchia e una nuova chiamata di sistema o
+dev'essere utilizzata da una chiamata di sistema e la sua variante compatibile,
+allora dev'essere implementata come una funzione di supporto
+(*helper function*) (per esempio ``kern_xyzzy()``). Questa funzione potrà
+essere chiamata dallo *stub* (``sys_xyzzy()``), dalla variante compatibile
+(``compat_sys_xyzzy()``), e/o da altri parti del kernel.
+
+Sui sistemi x86 a 64-bit, a partire dalla versione v4.17 è un requisito
+fondamentale quello di non invocare chiamate di sistema all'interno del kernel.
+Esso usa una diversa convenzione per l'invocazione di chiamate di sistema dove
+``struct pt_regs`` viene decodificata al volo in una funzione che racchiude
+la chiamata di sistema la quale verrà eseguita successivamente.
+Questo significa che verranno passati solo i parametri che sono davvero
+necessari ad una specifica chiamata di sistema, invece che riempire ogni volta
+6 registri del processore con contenuti presi dallo spazio utente (potrebbe
+causare seri problemi nella sequenza di chiamate).
+
+Inoltre, le regole su come i dati possano essere usati potrebbero differire
+fra il kernel e l'utente. Questo è un altro motivo per cui invocare
+``sys_xyzzy()`` è generalmente una brutta idea.
+
+Eccezioni a questa regola vengono accettate solo per funzioni d'architetture
+che surclassano quelle generiche, per funzioni d'architettura di compatibilità,
+o per altro codice in arch/

+Introduzione
+============
+
+Questo documento fornisce una lista dei software necessari per eseguire i
+kernel 4.x.
+
+Questo documento è basato sul file "Changes" del kernel 2.0.x e quindi le
+persone che lo scrissero meritano credito (Jared Mauch, Axel Boldt,
+Alessandro Sigala, e tanti altri nella rete).

+**almeno** alla versione indicata! Se non siete certi della versione che state
+usando, il comando indicato dovrebbe dirvelo.

+non tutti gli strumenti sono necessari ovunque; ovviamente, se non avete un
+modem ISDN, per esempio, probabilmente non dovreste preoccuparvi di
+isdn4k-utils.

+
+Compilazione del kernel
+***********************
+
+GCC
+---
+
+La versione necessaria di gcc potrebbe variare a seconda del tipo di CPU nel
+vostro calcolatore.
+
+Make
+----
+
+Per compilare il kernel vi servirà GNU make 3.81 o successivo.
+
+Binutils
+--------
+
+Il sistema di compilazione, dalla versione 4.13, per la produzione dei passi
+intermedi, si è convertito all'uso di *thin archive* (`ar T`) piuttosto che
+all'uso del *linking* incrementale (`ld -r`). Questo richiede binutils 2.20 o
+successivo.
+
+pkg-config
+----------
+
+Il sistema di compilazione, dalla versione 4.18, richiede pkg-config per
+verificare l'esistenza degli strumenti kconfig e per determinare le
+impostazioni da usare in 'make {g,x}config'. Precedentemente pkg-config
+veniva usato ma non verificato o documentato.
+
+Flex
+----
+
+Dalla versione 4.16, il sistema di compilazione, durante l'esecuzione, genera
+un analizzatore lessicale. Questo richiede flex 2.5.35 o successivo.
+
+Bison
+-----
+
+Dalla versione 4.16, il sistema di compilazione, durante l'esecuzione, genera
+un parsificatore. Questo richiede bison 2.0 o successivo.
+
+Perl
+----
+
+Per compilare il kernel vi servirà perl 5 e i seguenti moduli ``Getopt::Long``,
+``Getopt::Std``, ``File::Basename``, e ``File::Find``.
+
+BC
+--
+
+Vi servirà bc per compilare i kernel dal 3.10 in poi.
+
+OpenSSL
+-------
+
+Il programma OpenSSL e la libreria crypto vengono usati per la firma dei moduli
+e la gestione dei certificati; sono usati per la creazione della chiave e
+la generazione della firma.
+
+Se la firma dei moduli è abilitata, allora vi servirà openssl per compilare il
+kernel 3.7 e successivi. Vi serviranno anche i pacchetti di sviluppo di
+openssl per compilare il kernel 4.3 o successivi.
+
+
+Strumenti di sistema
+********************
+
+Modifiche architetturali
+------------------------
+
+DevFS è stato reso obsoleto da udev
+(http://www.kernel.org/pub/linux/utils/kernel/hotplug/)
+
+Il supporto per UID a 32-bit è ora disponibile. Divertitevi!
+
+La documentazione delle funzioni in Linux è una fase di transizione
+verso una documentazione integrata nei sorgenti stessi usando dei commenti
+formattati in modo speciale e posizionati vicino alle funzioni che descrivono.
+Al fine di arricchire la documentazione, questi commenti possono essere
+combinati con i file ReST presenti in Documentation/; questi potranno
+poi essere convertiti in formato PostScript, HTML, LaTex, ePUB o PDF.
+Per convertire i documenti da ReST al formato che volete, avete bisogno di
+Sphinx.
+
+Util-linux
+----------
+
+Le versioni più recenti di util-linux: forniscono il supporto a ``fdisk`` per
+dischi di grandi dimensioni; supportano le nuove opzioni di mount; riconoscono
+più tipi di partizioni; hanno un fdformat che funziona con i kernel 2.4;
+e altre chicche. Probabilmente vorrete aggiornarlo.
+
+Ksymoops
+--------
+
+Se l'impensabile succede e il kernel va in oops, potrebbe servirvi lo strumento
+ksymoops per decodificarlo, ma nella maggior parte dei casi non vi servirà.
+Generalmente è preferibile compilare il kernel con l'opzione ``CONFIG_KALLSYMS``
+cosicché venga prodotto un output più leggibile che può essere usato così com'è
+(produce anche un output migliore di ksymoops). Se per qualche motivo il
+vostro kernel non è stato compilato con ``CONFIG_KALLSYMS`` e non avete modo di
+ricompilarlo e riprodurre l'oops con quell'opzione abilitata, allora potete
+usare ksymoops per decodificare l'oops.
+
+Mkinitrd
+--------
+
+I cambiamenti della struttura in ``/lib/modules`` necessita l'aggiornamento di
+mkinitrd.
+
+E2fsprogs
+---------
+
+L'ultima versione di ``e2fsprogs`` corregge diversi bachi in fsck e debugfs.
+Ovviamente, aggiornarlo è una buona idea.
+
+JFSutils
+--------
+
+Il pacchetto ``jfsutils`` contiene programmi per il file-system JFS.
+Sono disponibili i seguenti strumenti:
+
+- ``fsck.jfs`` - avvia la ripetizione del log delle transizioni, e verifica e
+ ripara una partizione formattata secondo JFS
+
+- ``mkfs.jfs`` - crea una partizione formattata secondo JFS
+
+- sono disponibili altri strumenti per il file-system.
+
+Reiserfsprogs
+-------------
+
+Il pacchetto reiserfsprogs dovrebbe essere usato con reiserfs-3.6.x (Linux
+kernel 2.4.x). Questo è un pacchetto combinato che contiene versioni
+funzionanti di ``mkreiserfs``, ``resize_reiserfs``, ``debugreiserfs`` e
+``reiserfsck``. Questi programmi funzionano sulle piattaforme i386 e alpha.
+
+Xfsprogs
+--------
+
+L'ultima versione di ``xfsprogs`` contiene, fra i tanti, i programmi
+``mkfs.xfs``, ``xfs_db`` e ``xfs_repair`` per il file-system XFS.
+Dipendono dell'architettura e qualsiasi versione dalla 2.0.0 in poi
+dovrebbe funzionare correttamente con la versione corrente del codice
+XFS nel kernel (sono raccomandate le versioni 2.6.0 o successive per via
+di importanti miglioramenti).
+
+PCMCIAutils
+-----------
+
+PCMCIAutils sostituisce ``pcmica-cs``. Serve ad impostare correttamente i
+connettori PCMCIA all'avvio del sistema e a caricare i moduli necessari per
+i dispositivi a 16-bit se il kernel è stato modularizzato e il sottosistema
+hotplug è in uso.
+
+Quota-tools
+-----------
+
+Il supporto per uid e gid a 32 bit richiedono l'uso della versione 2 del
+formato quota. La versione 3.07 e successive di quota-tools supportano
+questo formato. Usate la versione raccomandata nella lista qui sopra o una
+successiva.
+
+Micro codice per Intel IA32
+---------------------------
+
+Per poter aggiornare il micro codice per Intel IA32, è stato aggiunto un
+apposito driver; il driver è accessibile come un normale dispositivo a
+caratteri (misc). Se non state usando udev probabilmente sarà necessario
+eseguire i seguenti comandi come root prima di poterlo aggiornare::
+
+ mkdir /dev/cpu
+ mknod /dev/cpu/microcode c 10 184
+ chmod 0644 /dev/cpu/microcode
+
+Probabilmente, vorrete anche il programma microcode_ctl da usare con questo
+dispositivo.
+
+udev
+----
+
+``udev`` è un programma in spazio utente il cui scopo è quello di popolare
+dinamicamente la cartella ``/dev`` coi dispositivi effettivamente presenti.
+``udev`` sostituisce le funzionalità base di devfs, consentendo comunque
+nomi persistenti per i dispositivi.
+
+FUSE
+----
+
+Serve libfuse 2.4.0 o successiva. Il requisito minimo assoluto è 2.3.0 ma
+le opzioni di mount ``direct_io`` e ``kernel_cache`` non funzioneranno.
+
+
+Rete
+****
+
+Cambiamenti generali
+--------------------
+
+Se per quanto riguarda la configurazione di rete avete esigenze di un certo
+livello dovreste prendere in considerazione l'uso degli strumenti in ip-route2.
+
+Filtro dei pacchetti / NAT
+--------------------------
+
+Il codice per filtraggio dei pacchetti e il NAT fanno uso degli stessi
+strumenti come nelle versioni del kernel antecedenti la 2.4.x (iptables).
+Include ancora moduli di compatibilità per 2.2.x ipchains e 2.0.x ipdwadm.
+
+PPP
+---
+
+Il driver per PPP è stato ristrutturato per supportare collegamenti multipli e
+per funzionare su diversi livelli. Se usate PPP, aggiornate pppd almeno alla
+versione 2.4.0.
+
+Se non usate udev, dovete avere un file /dev/ppp che può essere creato da root
+col seguente comando::
+
+ mknod /dev/ppp c 108 0
+
+Isdn4k-utils
+------------
+
+Per via della modifica del campo per il numero di telefono, il pacchetto
+isdn4k-utils dev'essere ricompilato o (preferibilmente) aggiornato.
+
+NFS-utils
+---------
+
+Nei kernel più antichi (2.4 e precedenti), il server NFS doveva essere
+informato sui clienti ai quali si voleva fornire accesso via NFS. Questa
+informazione veniva passata al kernel quando un cliente montava un file-system
+mediante ``mountd``, oppure usando ``exportfs`` all'avvio del sistema.
+exportfs prende le informazioni circa i clienti attivi da ``/var/lib/nfs/rmtab``.
+
+Questo approccio è piuttosto delicato perché dipende dalla correttezza di
+rmtab, che non è facile da garantire, in particolare quando si cerca di
+implementare un *failover*. Anche quando il sistema funziona bene, ``rmtab``
+ha il problema di accumulare vecchie voci inutilizzate.
+
+Sui kernel più recenti il kernel ha la possibilità di informare mountd quando
+arriva una richiesta da una macchina sconosciuta, e mountd può dare al kernel
+le informazioni corrette per l'esportazione. Questo rimuove la dipendenza con
+``rmtab`` e significa che il kernel deve essere al corrente solo dei clienti
+attivi.
+
+Per attivare questa funzionalità, dovete eseguire il seguente comando prima di
+usare exportfs o mountd::
+
+ mount -t nfsd nfsd /proc/fs/nfsd
+
+Dove possibile, raccomandiamo di proteggere tutti i servizi NFS dall'accesso
+via internet mediante un firewall.
+
+mcelog
+------
+
+Quando ``CONFIG_x86_MCE`` è attivo, il programma mcelog processa e registra
+gli eventi *machine check*. Gli eventi *machine check* sono errori riportati
+dalla CPU. Incoraggiamo l'analisi di questi errori.

+clang-format
+============
+``clang-format`` è uno strumento per formattare codice C/C++/... secondo
+un gruppo di regole ed euristiche. Come tutti gli strumenti, non è perfetto
+e non copre tutti i singoli casi, ma è abbastanza buono per essere utile.
+
+``clang-format`` può essere usato per diversi fini:
+
+ - Per riformattare rapidamente un blocco di codice secondo lo stile del
+ kernel. Particolarmente utile quando si sposta del codice e lo si
+ allinea/ordina. Vedere it_clangformatreformat_.
+
+ - Identificare errori di stile, refusi e possibili miglioramenti nei
+ file che mantieni, le modifiche che revisioni, le differenze,
+ eccetera. Vedere it_clangformatreview_.
+
+ - Ti aiuta a seguire lo stile del codice, particolarmente utile per i
+ nuovi arrivati o per coloro che lavorano allo stesso tempo su diversi
+ progetti con stili di codifica differenti.
+
+Il suo file di configurazione è ``.clang-format`` e si trova nella cartella
+principale dei sorgenti del kernel. Le regole scritte in quel file tentano
+di approssimare le lo stile di codifica del kernel. Si tenta anche di seguire
+il più possibile
+:ref:`Documentation/translations/it_IT/process/coding-style.rst <it_codingstyle>`.
+Dato che non tutto il kernel segue lo stesso stile, potreste voler aggiustare
+le regole di base per un particolare sottosistema o cartella. Per farlo,
+potete sovrascriverle scrivendole in un altro file ``.clang-format`` in
+una sottocartella.
+
+Questo strumento è già stato incluso da molto tempo nelle distribuzioni
+Linux più popolari. Cercate ``clang-format`` nel vostro repositorio.
+Altrimenti, potete scaricare una versione pre-generata dei binari di LLVM/clang
+oppure generarlo dai codici sorgenti:
+
+ http://releases.llvm.org/download.html
+
+Troverete più informazioni ai seguenti indirizzi:
+
+ https://clang.llvm.org/docs/ClangFormat.html
+
+ https://clang.llvm.org/docs/ClangFormatStyleOptions.html
+
+
+.. _it_clangformatreview:
+
+Revisionare lo stile di codifica per file e modifiche
+-----------------------------------------------------
+
+Eseguendo questo programma, potrete revisionare un intero sottosistema,
+cartella o singoli file alla ricerca di errori di stile, refusi o
+miglioramenti.
+
+Per farlo, potete eseguire qualcosa del genere::
+
+ # Make sure your working directory is clean!
+ clang-format -i kernel/*.[ch]
+
+E poi date un'occhiata a *git diff*.
+
+Osservare le righe di questo diff è utile a migliorare/aggiustare
+le opzioni di stile nel file di configurazione; così come per verificare
+le nuove funzionalità/versioni di ``clang-format``.
+
+``clang-format`` è in grado di leggere diversi diff unificati, quindi
+potrete revisionare facilmente delle modifiche e *git diff*.
+La documentazione si trova al seguente indirizzo:
+
+ https://clang.llvm.org/docs/ClangFormat.html#script-for-patch-reformatting
+
+Per evitare che ``clang-format`` formatti alcune parti di un file, potete
+scrivere nel codice::
+
+ int formatted_code;
+ // clang-format off
+ void unformatted_code ;
+ // clang-format on
+ void formatted_code_again;
+
+Nonostante si attraente l'idea di utilizzarlo per mantenere un file
+sempre in sintonia con ``clang-format``, specialmente per file nuovi o
+se siete un manutentore, ricordatevi che altre persone potrebbero usare
+una versione diversa di ``clang-format`` oppure non utilizzarlo del tutto.
+Quindi, dovreste trattenervi dall'usare questi marcatori nel codice del
+kernel; almeno finché non vediamo che ``clang-format`` è diventato largamente
+utilizzato.

+------------------------------
+
+Utilizzando dei plugin per il vostro editor, potete riformattare una
+blocco (selezione) di codice con una singola combinazione di tasti.
+Questo è particolarmente utile: quando si riorganizza il codice, per codice
+complesso, macro multi-riga (e allineare le loro "barre"), eccetera.
+
+Ricordatevi che potete sempre aggiustare le modifiche in quei casi dove
+questo strumento non ha fatto un buon lavoro. Ma come prima approssimazione,
+può essere davvero molto utile.
+
+Questo programma si integra con molti dei più popolari editor. Alcuni di
+essi come vim, emacs, BBEdit, Visaul Studio, lo supportano direttamente.
+Al seguente indirizzo troverete le istruzioni:
+
+ https://clang.llvm.org/docs/ClangFormat.html
+
+Per Atom, Eclipse, Sublime Text, Visual Studio Code, XCode e altri editor
+e IDEs dovreste essere in grado di trovare dei plugin pronti all'uso.
+
+Per questo caso d'uso, considerate l'uso di un secondo ``.clang-format``
+che potete personalizzare con le vostre opzioni.
+Consultare it_clangformatextra_.
+
+
+.. _it_clangformatmissing:
+
+Cose non supportate
+-------------------
+
+``clang-format`` non ha il supporto per alcune cose che sono comuni nel
+codice del kernel. Sono facili da ricordare; quindi, se lo usate
+regolarmente, imparerete rapidamente a evitare/ignorare certi problemi.
+
+In particolare, quelli più comuni che noterete sono:
+
+ - Allineamento di ``#define`` su una singola riga, per esempio::
+
+ #define TRACING_MAP_BITS_DEFAULT 11
+ #define TRACING_MAP_BITS_MAX 17
+ #define TRACING_MAP_BITS_MIN 7
+
+ contro::
+
+ #define TRACING_MAP_BITS_DEFAULT 11
+ #define TRACING_MAP_BITS_MAX 17
+ #define TRACING_MAP_BITS_MIN 7
+
+ - Allineamento dei valori iniziali, per esempio::
+
+ static const struct file_operations uprobe_events_ops = {
+ .owner = THIS_MODULE,
+ .open = probes_open,
+ .read = seq_read,
+ .llseek = seq_lseek,
+ .release = seq_release,
+ .write = probes_write,
+ };
+
+ contro::
+
+ static const struct file_operations uprobe_events_ops = {
+ .owner = THIS_MODULE,
+ .open = probes_open,
+ .read = seq_read,
+ .llseek = seq_lseek,
+ .release = seq_release,
+ .write = probes_write,
+ };
+
+
+.. _it_clangformatextra:
+
+Funzionalità e opzioni aggiuntive
+---------------------------------
+
+Al fine di minimizzare le differenze fra il codice attuale e l'output
+del programma, alcune opzioni di stile e funzionalità non sono abilitate
+nella configurazione base. In altre parole, lo scopo è di rendere le
+differenze le più piccole possibili, permettendo la semplificazione
+della revisione di file, differenze e modifiche.
+
+In altri casi (per esempio un particolare sottosistema/cartella/file), lo
+stile del kernel potrebbe essere diverso e abilitare alcune di queste
+opzioni potrebbe dare risultati migliori.
+
+Per esempio:
+
+ - Allineare assegnamenti (``AlignConsecutiveAssignments``).
+
+ - Allineare dichiarazioni (``AlignConsecutiveDeclarations``).
+
+ - Riorganizzare il testo nei commenti (``ReflowComments``).
+
+ - Ordinare gli ``#include`` (``SortIncludes``).
+
+Piuttosto che per interi file, solitamente sono utili per la riformattazione
+di singoli blocchi. In alternativa, potete creare un altro file
+``.clang-format`` da utilizzare con il vostro editor/IDE.

+
+Stile del codice per il kernel Linux
+====================================
+
+Questo è un breve documento che descrive lo stile di codice preferito per
+il kernel Linux. Lo stile di codifica è molto personale e non voglio
+**forzare** nessuno ad accettare il mio, ma questo stile è quello che
+dev'essere usato per qualsiasi cosa che io sia in grado di mantenere, e l'ho
+preferito anche per molte altre cose. Per favore, almeno tenete in
+considerazione le osservazioni espresse qui.
+
+La prima cosa che suggerisco è quella di stamparsi una copia degli standard
+di codifica GNU e di NON leggerla. Bruciatela, è un grande gesto simbolico.
+
+Comunque, ecco i punti:
+
+1) Indentazione
+---------------
+
+La tabulazione (tab) è di 8 caratteri e così anche le indentazioni. Ci sono
+alcuni movimenti di eretici che vorrebbero l'indentazione a 4 (o perfino 2!)
+caratteri di profondità, che è simile al tentativo di definire il valore del
+pi-greco a 3.
+
+Motivazione: l'idea dell'indentazione è di definire chiaramente dove un blocco
+di controllo inizia e finisce. Specialmente quando siete rimasti a guardare lo
+schermo per 20 ore a file, troverete molto più facile capire i livelli di
+indentazione se questi sono larghi.
+
+Ora, alcuni rivendicano che un'indentazione da 8 caratteri sposta il codice
+troppo a destra e che quindi rende difficile la lettura su schermi a 80
+caratteri. La risposta a questa affermazione è che se vi servono più di 3
+livelli di indentazione, siete comunque fregati e dovreste correggere il vostro
+programma.
+
+In breve, l'indentazione ad 8 caratteri rende più facile la lettura, e in
+aggiunta vi avvisa quando state annidando troppo le vostre funzioni.
+Tenete ben a mente questo avviso.
+
+Al fine di facilitare l'indentazione del costrutto switch, si preferisce
+allineare sulla stessa colonna la parola chiave ``switch`` e i suoi
+subordinati ``case``. In questo modo si evita una doppia indentazione per
+i ``case``. Un esempio.:
+
+.. code-block:: c
+
+ switch (suffix) {
+ case 'G':
+ case 'g':
+ mem <<= 30;
+ break;
+ case 'M':
+ case 'm':
+ mem <<= 20;
+ break;
+ case 'K':
+ case 'k':
+ mem <<= 10;
+ /* fall through */
+ default:
+ break;
+ }
+
+A meno che non vogliate nascondere qualcosa, non mettete più istruzioni sulla
+stessa riga:
+
+.. code-block:: c
+
+ if (condition) do_this;
+ do_something_everytime;
+
+né mettete più assegnamenti sulla stessa riga. Lo stile del kernel
+è ultrasemplice. Evitate espressioni intricate.
+
+Al di fuori dei commenti, della documentazione ed escludendo i Kconfig, gli
+spazi non vengono mai usati per l'indentazione, e l'esempio qui sopra è
+volutamente errato.
+
+Procuratevi un buon editor di testo e non lasciate spazi bianchi alla fine
+delle righe.
+
+
+2) Spezzare righe lunghe e stringhe
+-----------------------------------
+
+Lo stile del codice riguarda la leggibilità e la manutenibilità utilizzando
+strumenti comuni.
+
+Il limite delle righe è di 80 colonne e questo e un limite fortemente
+desiderato.
+
+Espressioni più lunghe di 80 colonne saranno spezzettate in pezzi più piccoli,
+a meno che eccedere le 80 colonne non aiuti ad aumentare la leggibilità senza
+nascondere informazioni. I pezzi derivati sono sostanzialmente più corti degli
+originali e vengono posizionati più a destra. Lo stesso si applica, nei file
+d'intestazione, alle funzioni con una lista di argomenti molto lunga. Tuttavia,
+non spezzettate mai le stringhe visibili agli utenti come i messaggi di
+printk, questo perché inibireste la possibilità d'utilizzare grep per cercarle.
+
+3) Posizionamento di parentesi graffe e spazi
+---------------------------------------------
+
+Un altro problema che s'affronta sempre quando si parla di stile in C è
+il posizionamento delle parentesi graffe. Al contrario della dimensione
+dell'indentazione, non ci sono motivi tecnici sulla base dei quali scegliere
+una strategia di posizionamento o un'altra; ma il modo qui preferito,
+come mostratoci dai profeti Kernighan e Ritchie, è quello di
+posizionare la parentesi graffa di apertura per ultima sulla riga, e quella
+di chiusura per prima su una nuova riga, così:
+
+.. code-block:: c
+
+ if (x is true) {
+ we do y
+ }
+
+Questo è valido per tutte le espressioni che non siano funzioni (if, switch,
+for, while, do). Per esempio:
+
+.. code-block:: c
+
+ switch (action) {
+ case KOBJ_ADD:
+ return "add";
+ case KOBJ_REMOVE:
+ return "remove";
+ case KOBJ_CHANGE:
+ return "change";
+ default:
+ return NULL;
+ }
+
+Tuttavia, c'è il caso speciale, le funzioni: queste hanno la parentesi graffa
+di apertura all'inizio della riga successiva, quindi:
+
+.. code-block:: c
+
+ int function(int x)
+ {
+ body of function
+ }
+
+Eretici da tutto il mondo affermano che questa incoerenza è ...
+insomma ... incoerente, ma tutte le persone ragionevoli sanno che (a)
+K&R hanno **ragione** e (b) K&R hanno ragione. A parte questo, le funzioni
+sono comunque speciali (non potete annidarle in C).
+
+Notate che la graffa di chiusura è da sola su una riga propria, ad
+**eccezione** di quei casi dove è seguita dalla continuazione della stessa
+espressione, in pratica ``while`` nell'espressione do-while, oppure ``else``
+nell'espressione if-else, come questo:
+
+.. code-block:: c
+
+ do {
+ body of do-loop
+ } while (condition);
+
+e
+
+.. code-block:: c
+
+ if (x == y) {
+ ..
+ } else if (x > y) {
+ ...
+ } else {
+ ....
+ }
+
+Motivazione: K&R.
+
+Inoltre, notate che questo posizionamento delle graffe minimizza il numero
+di righe vuote senza perdere di leggibilità. In questo modo, dato che le
+righe sul vostro schermo non sono una risorsa illimitata (pensate ad uno
+terminale con 25 righe), avrete delle righe vuote da riempire con dei
+commenti.
+
+Non usate inutilmente le graffe dove una singola espressione è sufficiente.
+
+.. code-block:: c
+
+ if (condition)
+ action();
+
+e
+
+.. code-block:: none
+
+ if (condition)
+ do_this();
+ else
+ do_that();
+
+Questo non vale nel caso in cui solo un ramo dell'espressione if-else
+contiene una sola espressione; in quest'ultimo caso usate le graffe per
+entrambe i rami:
+
+.. code-block:: c
+
+ if (condition) {
+ do_this();
+ do_that();
+ } else {
+ otherwise();
+ }
+
+Inoltre, usate le graffe se un ciclo contiene più di una semplice istruzione:
+
+.. code-block:: c
+
+ while (condition) {
+ if (test)
+ do_something();
+ }
+
+3.1) Spazi
+**********
+
+Lo stile del kernel Linux per quanto riguarda gli spazi, dipende
+(principalmente) dalle funzioni e dalle parole chiave. Usate una spazio dopo
+(quasi tutte) le parole chiave. L'eccezioni più evidenti sono sizeof, typeof,
+alignof, e __attribute__, il cui aspetto è molto simile a quello delle
+funzioni (e in Linux, solitamente, sono usate con le parentesi, anche se il
+linguaggio non lo richiede; come ``sizeof info`` dopo aver dichiarato
+``struct fileinfo info``).
+
+Quindi utilizzate uno spazio dopo le seguenti parole chiave::
+
+ if, switch, case, for, do, while
+
+ma non con sizeof, typeof, alignof, o __attribute__. Ad esempio,
+
+.. code-block:: c
+
+
+ s = sizeof(struct file);
+
+Non aggiungete spazi attorno (dentro) ad un'espressione fra parentesi. Questo
+esempio è **brutto**:
+
+.. code-block:: c
+
+
+ s = sizeof( struct file );
+
+Quando dichiarate un puntatore ad una variabile o una funzione che ritorna un
+puntatore, il posto suggerito per l'asterisco ``*`` è adiacente al nome della
+variabile o della funzione, e non adiacente al nome del tipo. Esempi:
+
+.. code-block:: c
+
+
+ char *linux_banner;
+ unsigned long long memparse(char *ptr, char **retptr);
+ char *match_strdup(substring_t *s);
+
+Usate uno spazio attorno (da ogni parte) alla maggior parte degli operatori
+binari o ternari, come i seguenti::
+
+ = + - < > * / % | & ^ <= >= == != ? :
+
+ma non mettete spazi dopo gli operatori unari::
+
+ & * + - ~ ! sizeof typeof alignof __attribute__ defined
+
+nessuno spazio dopo l'operatore unario suffisso di incremento o decremento::
+
+ ++ --
+
+nessuno spazio dopo l'operatore unario prefisso di incremento o decremento::
+
+ ++ --
+
+e nessuno spazio attorno agli operatori dei membri di una struttura ``.`` e
+``->``.
+
+Non lasciate spazi bianchi alla fine delle righe. Alcuni editor con
+l'indentazione ``furba`` inseriranno gli spazi bianchi all'inizio di una nuova
+riga in modo appropriato, quindi potrete scrivere la riga di codice successiva
+immediatamente. Tuttavia, alcuni di questi stessi editor non rimuovono
+questi spazi bianchi quando non scrivete nulla sulla nuova riga, ad esempio
+perché volete lasciare una riga vuota. Il risultato è che finirete per avere
+delle righe che contengono spazi bianchi in coda.
+
+Git vi avviserà delle modifiche che aggiungono questi spazi vuoti di fine riga,
+e può opzionalmente rimuoverli per conto vostro; tuttavia, se state applicando
+una serie di modifiche, questo potrebbe far fallire delle modifiche successive
+perché il contesto delle righe verrà cambiato.
+
+4) Assegnare nomi
+-----------------
+
+C è un linguaggio spartano, e così dovrebbero esserlo i vostri nomi. Al
+contrario dei programmatori Modula-2 o Pascal, i programmatori C non usano
+nomi graziosi come ThisVariableIsATemporaryCounter. Un programmatore C
+chiamerebbe questa variabile ``tmp``, che è molto più facile da scrivere e
+non è una delle più difficili da capire.
+
+TUTTAVIA, nonostante i nomi con notazione mista siano da condannare, i nomi
+descrittivi per variabili globali sono un dovere. Chiamare una funzione
+globale ``pippo`` è un insulto.
+
+Le variabili GLOBALI (da usare solo se vi servono **davvero**) devono avere
+dei nomi descrittivi, così come le funzioni globali. Se avete una funzione
+che conta gli utenti attivi, dovreste chiamarla ``count_active_users()`` o
+qualcosa di simile, **non** dovreste chiamarla ``cntusr()``.
+
+Codificare il tipo di funzione nel suo nome (quella cosa chiamata notazione
+ungherese) fa male al cervello - il compilatore conosce comunque il tipo e
+può verificarli, e inoltre confonde i programmatori. Non c'è da
+sorprendersi che MicroSoft faccia programmi bacati.
+
+Le variabili LOCALI dovrebbero avere nomi corti, e significativi. Se avete
+un qualsiasi contatore di ciclo, probabilmente sarà chiamato ``i``.
+Chiamarlo ``loop_counter`` non è produttivo, non ci sono possibilità che
+``i`` possa non essere capito. Analogamente, ``tmp`` può essere una qualsiasi
+variabile che viene usata per salvare temporaneamente un valore.
+
+Se avete paura di fare casino coi nomi delle vostre variabili locali, allora
+avete un altro problema che è chiamato sindrome dello squilibrio dell'ormone
+della crescita delle funzioni. Vedere il capitolo 6 (funzioni).
+
+5) Definizione di tipi (typedef)
+--------------------------------
+
+Per favore non usate cose come ``vps_t``.
+Usare il typedef per strutture e puntatori è uno **sbaglio**. Quando vedete:
+
+.. code-block:: c
+
+ vps_t a;
+
+nei sorgenti, cosa significa?
+Se, invece, dicesse:
+
+.. code-block:: c
+
+ struct virtual_container *a;
+
+potreste dire cos'è effettivamente ``a``.
+
+Molte persone pensano che la definizione dei tipi ``migliori la leggibilità``.
+Non molto. Sono utili per:
+
+ (a) gli oggetti completamente opachi (dove typedef viene proprio usato allo
+ scopo di **nascondere** cosa sia davvero l'oggetto).
+
+ Esempio: ``pte_t`` eccetera sono oggetti opachi che potete usare solamente
+ con le loro funzioni accessorie.
+
+ .. note::
+ Gli oggetti opachi e le ``funzioni accessorie`` non sono, di per se,
+ una bella cosa. Il motivo per cui abbiamo cose come pte_t eccetera è
+ che davvero non c'è alcuna informazione portabile.
+
+ (b) i tipi chiaramente interi, dove l'astrazione **aiuta** ad evitare
+ confusione sul fatto che siano ``int`` oppure ``long``.
+
+ u8/u16/u32 sono typedef perfettamente accettabili, anche se ricadono
+ nella categoria (d) piuttosto che in questa.
+
+ .. note::
+
+ Ancora - dev'esserci una **ragione** per farlo. Se qualcosa è
+ ``unsigned long``, non c'è alcun bisogno di avere:
+
+ typedef unsigned long myfalgs_t;
+
+ ma se ci sono chiare circostanze in cui potrebbe essere ``unsigned int``
+ e in altre configurazioni ``unsigned long``, allora certamente typedef
+ è una buona scelta.
+
+ (c) quando di rado create letteralmente dei **nuovi** tipi su cui effettuare
+ verifiche.
+
+ (d) circostanze eccezionali, in cui si definiscono nuovi tipi identici a
+ quelli definiti dallo standard C99.
+
+ Nonostante ci voglia poco tempo per abituare occhi e cervello all'uso dei
+ tipi standard come ``uint32_t``, alcune persone ne obiettano l'uso.
+
+ Perciò, i tipi specifici di Linux ``u8/u16/u32/u64`` e i loro equivalenti
+ con segno, identici ai tipi standard, sono permessi- tuttavia, non sono
+ obbligatori per il nuovo codice.
+
+ (e) i tipi sicuri nella spazio utente.
+
+ In alcune strutture dati visibili dallo spazio utente non possiamo
+ richiedere l'uso dei tipi C99 e nemmeno i vari ``u32`` descritti prima.
+ Perciò, utilizziamo __u32 e tipi simili in tutte le strutture dati
+ condivise con lo spazio utente.
+
+Magari ci sono altri casi validi, ma la regola di base dovrebbe essere di
+non usare MAI MAI un typedef a meno che non rientri in una delle regole
+descritte qui.
+
+In generale, un puntatore, o una struttura a cui si ha accesso diretto in
+modo ragionevole, non dovrebbero **mai** essere definite con un typedef.
+
+6) Funzioni
+-----------
+
+Le funzioni dovrebbero essere brevi e carine, e fare una cosa sola. Dovrebbero
+occupare uno o due schermi di testo (come tutti sappiamo, la dimensione
+di uno schermo secondo ISO/ANSI è di 80x24), e fare una cosa sola e bene.
+
+La massima lunghezza di una funziona è inversamente proporzionale alla sua
+complessità e al livello di indentazione di quella funzione. Quindi, se avete
+una funzione che è concettualmente semplice ma che è implementata come un
+lunga (ma semplice) sequenza di caso-istruzione, dove avete molte piccole cose
+per molti casi differenti, allora va bene avere funzioni più lunghe.
+
+Comunque, se avete una funzione complessa e sospettate che uno studente
+non particolarmente dotato del primo anno delle scuole superiori potrebbe
+non capire cosa faccia la funzione, allora dovreste attenervi strettamente ai
+limiti. Usate funzioni di supporto con nomi descrittivi (potete chiedere al
+compilatore di renderle inline se credete che sia necessario per le
+prestazioni, e probabilmente farà un lavoro migliore di quanto avreste potuto
+fare voi).
+
+Un'altra misura delle funzioni sono il numero di variabili locali. Non
+dovrebbero eccedere le 5-10, oppure state sbagliando qualcosa. Ripensate la
+funzione, e dividetela in pezzettini. Generalmente, un cervello umano può
+seguire facilmente circa 7 cose diverse, di più lo confonderebbe. Lo sai
+d'essere brillante, ma magari vorresti riuscire a capire cos'avevi fatto due
+settimane prima.
+
+Nei file sorgenti, separate le funzioni con una riga vuota. Se la funzione è
+esportata, la macro **EXPORT** per questa funzione deve seguire immediatamente
+la riga della parentesi graffa di chiusura. Ad esempio:
+
+.. code-block:: c
+
+ int system_is_up(void)
+ {
+ return system_state == SYSTEM_RUNNING;
+ }
+ EXPORT_SYMBOL(system_is_up);
+
+Nei prototipi di funzione, includete i nomi dei parametri e i loro tipi.
+Nonostante questo non sia richiesto dal linguaggio C, in Linux viene preferito
+perché è un modo semplice per aggiungere informazioni importanti per il
+lettore.
+
+Non usate la parola chiave ``extern`` coi prototipi di funzione perché
+rende le righe più lunghe e non è strettamente necessario.
+
+7) Centralizzare il ritorno delle funzioni
+------------------------------------------
+
+Sebbene sia deprecata da molte persone, l'istruzione goto è impiegata di
+frequente dai compilatori sotto forma di salto incondizionato.
+
+L'istruzione goto diventa utile quando una funzione ha punti d'uscita multipli
+e vanno eseguite alcune procedure di pulizia in comune. Se non è necessario
+pulire alcunché, allora ritornate direttamente.
+
+Assegnate un nome all'etichetta di modo che suggerisca cosa fa la goto o
+perché esiste. Un esempio di un buon nome potrebbe essere ``out_free_buffer:``
+se la goto libera (free) un ``buffer``. Evitate l'uso di nomi GW-BASIC come
+``err1:`` ed ``err2:``, potreste doverli riordinare se aggiungete o rimuovete
+punti d'uscita, e inoltre rende difficile verificarne la correttezza.
+
+I motivo per usare le goto sono:
+
+- i salti incondizionati sono più facili da capire e seguire
+- l'annidamento si riduce
+- si evita di dimenticare, per errore, di aggiornare un singolo punto d'uscita
+- aiuta il compilatore ad ottimizzare il codice ridondante ;)
+
+.. code-block:: c
+
+ int fun(int a)
+ {
+ int result = 0;
+ char *buffer;
+
+ buffer = kmalloc(SIZE, GFP_KERNEL);
+ if (!buffer)
+ return -ENOMEM;
+
+ if (condition1) {
+ while (loop1) {
+ ...
+ }
+ result = 1;
+ goto out_free_buffer;
+ }
+ ...
+ out_free_buffer:
+ kfree(buffer);
+ return result;
+ }
+
+Un baco abbastanza comune di cui bisogna prendere nota è il ``one err bugs``
+che assomiglia a questo:
+
+.. code-block:: c
+
+ err:
+ kfree(foo->bar);
+ kfree(foo);
+ return ret;
+
+Il baco in questo codice è che in alcuni punti d'uscita la variabile ``foo`` è
+NULL. Normalmente si corregge questo baco dividendo la gestione dell'errore in
+due parti ``err_free_bar:`` e ``err_free_foo:``:
+
+.. code-block:: c
+
+ err_free_bar:
+ kfree(foo->bar);
+ err_free_foo:
+ kfree(foo);
+ return ret;
+
+Idealmente, dovreste simulare condizioni d'errore per verificare i vostri
+percorsi d'uscita.
+
+
+8) Commenti
+-----------
+
+I commenti sono una buona cosa, ma c'è anche il rischio di esagerare. MAI
+spiegare COME funziona il vostro codice in un commento: è molto meglio
+scrivere il codice di modo che il suo funzionamento sia ovvio, inoltre
+spiegare codice scritto male è una perdita di tempo.
+
+Solitamente, i commenti devono dire COSA fa il codice, e non COME lo fa.
+Inoltre, cercate di evitare i commenti nel corpo della funzione: se la
+funzione è così complessa che dovete commentarla a pezzi, allora dovreste
+tornare al punto 6 per un momento. Potete mettere dei piccoli commenti per
+annotare o avvisare il lettore circa un qualcosa di particolarmente arguto
+(o brutto), ma cercate di non esagerare. Invece, mettete i commenti in
+testa alla funzione spiegando alle persone cosa fa, e possibilmente anche
+il PERCHÉ.
+
+Per favore, quando commentate una funzione dell'API del kernel usate il
+formato kernel-doc. Per maggiori dettagli, leggete i file in
+:ref::ref:`Documentation/translations/it_IT/doc-guide/ <it_doc_guide>` e in
+``script/kernel-doc``.
+
+Lo stile preferito per i commenti più lunghi (multi-riga) è:
+
+.. code-block:: c
+
+ /*
+ * This is the preferred style for multi-line
+ * comments in the Linux kernel source code.
+ * Please use it consistently.
+ *
+ * Description: A column of asterisks on the left side,
+ * with beginning and ending almost-blank lines.
+ */
+
+Per i file in net/ e in drivers/net/ lo stile preferito per i commenti
+più lunghi (multi-riga) è leggermente diverso.
+
+.. code-block:: c
+
+ /* The preferred comment style for files in net/ and drivers/net
+ * looks like this.
+ *
+ * It is nearly the same as the generally preferred comment style,
+ * but there is no initial almost-blank line.
+ */
+
+È anche importante commentare i dati, sia per i tipi base che per tipi
+derivati. A questo scopo, dichiarate un dato per riga (niente virgole
+per una dichiarazione multipla). Questo vi lascerà spazio per un piccolo
+commento per spiegarne l'uso.
+
+
+9) Avete fatto un pasticcio
+---------------------------
+
+Va bene, li facciamo tutti. Probabilmente vi è stato detto dal vostro
+aiutante Unix di fiducia che ``GNU emacs`` formatta automaticamente il
+codice C per conto vostro, e avete notato che sì, in effetti lo fa, ma che
+i modi predefiniti non sono proprio allettanti (infatti, sono peggio che
+premere tasti a caso - un numero infinito di scimmie che scrivono in
+GNU emacs non faranno mai un buon programma).
+
+Quindi, potete sbarazzarvi di GNU emacs, o riconfigurarlo con valori più
+sensati. Per fare quest'ultima cosa, potete appiccicare il codice che
+segue nel vostro file .emacs:
+
+.. code-block:: none
+
+ (defun c-lineup-arglist-tabs-only (ignored)
+ "Line up argument lists by tabs, not spaces"
+ (let* ((anchor (c-langelem-pos c-syntactic-element))
+ (column (c-langelem-2nd-pos c-syntactic-element))
+ (offset (- (1+ column) anchor))
+ (steps (floor offset c-basic-offset)))
+ (* (max steps 1)

+
+Questo farà funzionare meglio emacs con lo stile del kernel per i file che
+si trovano nella cartella ``~/src/linux-trees``.
+
+Ma anche se doveste fallire nell'ottenere una formattazione sensata in emacs
+non tutto è perduto: usate ``indent``.
+
+Ora, ancora, GNU indent ha la stessa configurazione decerebrata di GNU emacs,
+ed è per questo che dovete passargli alcune opzioni da riga di comando.
+Tuttavia, non è così terribile, perché perfino i creatori di GNU indent
+riconoscono l'autorità di K&R (le persone del progetto GNU non sono cattive,
+sono solo mal indirizzate sull'argomento), quindi date ad indent le opzioni
+``-kr -i8`` (che significa ``K&R, 8 caratteri di indentazione``), o utilizzate
+``scripts/Lindent`` che indenterà usando l'ultimo stile.
+
+``indent`` ha un sacco di opzioni, e specialmente quando si tratta di
+riformattare i commenti dovreste dare un'occhiata alle pagine man.
+Ma ricordatevi: ``indent`` non è un correttore per una cattiva programmazione.
+
+Da notare che potete utilizzare anche ``clang-format`` per aiutarvi con queste
+regole, per riformattare rapidamente ad automaticamente alcune parti del
+vostro codice, e per revisionare interi file al fine di identificare errori
+di stile, refusi e possibilmente anche delle migliorie. È anche utile per
+ordinare gli ``#include``, per allineare variabili/macro, per ridistribuire
+il testo e altre cose simili.
+Per maggiori dettagli, consultate il file
+:ref:`Documentation/translations/it_IT/process/clang-format.rst <it_clangformat>`.
+
+
+10) File di configurazione Kconfig
+----------------------------------
+
+Per tutti i file di configurazione Kconfig* che si possono trovare nei
+sorgenti, l'indentazione è un po' differente. Le linee dopo un ``config``
+sono indentate con un tab, mentre il testo descrittivo è indentato di
+ulteriori due spazi. Esempio::
+
+ config AUDIT
+ bool "Auditing support"
+ depends on NET
+ help
+ Enable auditing infrastructure that can be used with another
+ kernel subsystem, such as SELinux (which requires this for
+ logging of avc messages output). Does not do system-call
+ auditing without CONFIG_AUDITSYSCALL.
+
+Le funzionalità davvero pericolose (per esempio il supporto alla scrittura
+per certi filesystem) dovrebbero essere dichiarate chiaramente come tali
+nella stringa di titolo::
+
+ config ADFS_FS_RW
+ bool "ADFS write support (DANGEROUS)"
+ depends on ADFS_FS
+ ...
+
+Per la documentazione completa sui file di configurazione, consultate
+il documento Documentation/translations/it_IT/kbuild/kconfig-language.txt
+
+
+11) Strutture dati
+------------------
+
+Le strutture dati che hanno una visibilità superiore al contesto del
+singolo thread in cui vengono create e distrutte, dovrebbero sempre
+avere un contatore di riferimenti. Nel kernel non esiste un
+*garbage collector* (e fuori dal kernel i *garbage collector* sono lenti
+e inefficienti), questo significa che **dovete** assolutamente avere un
+contatore di riferimenti per ogni cosa che usate.
+
+Avere un contatore di riferimenti significa che potete evitare la
+sincronizzazione e permette a più utenti di accedere alla struttura dati
+in parallelo - e non doversi preoccupare di una struttura dati che
+improvvisamente sparisce dalla loro vista perché il loro processo dormiva
+o stava facendo altro per un attimo.
+
+Da notare che la sincronizzazione **non** si sostituisce al conteggio dei
+riferimenti. La sincronizzazione ha lo scopo di mantenere le strutture
+dati coerenti, mentre il conteggio dei riferimenti è una tecnica di gestione
+della memoria. Solitamente servono entrambe le cose, e non vanno confuse fra
+di loro.
+
+Quando si hanno diverse classi di utenti, le strutture dati possono avere
+due livelli di contatori di riferimenti. Il contatore di classe conta
+il numero dei suoi utenti, e il contatore globale viene decrementato una
+sola volta quando il contatore di classe va a zero.
+
+Un esempio di questo tipo di conteggio dei riferimenti multi-livello può
+essere trovato nella gestore della memoria (``struct mm_sturct``: mm_user e
+mm_count), e nel codice dei filesystem (``struct super_block``: s_count e
+s_active).
+
+Ricordatevi: se un altro thread può trovare la vostra struttura dati, e non
+avete un contatore di riferimenti per essa, quasi certamente avete un baco.
+
+12) Macro, enumerati e RTL
+---------------------------
+
+I nomi delle macro che definiscono delle costanti e le etichette degli
+enumerati sono scritte in maiuscolo.
+
+.. code-block:: c
+
+ #define CONSTANT 0x12345
+
+Gli enumerati sono da preferire quando si definiscono molte costanti correlate.
+
+I nomi delle macro in MAIUSCOLO sono preferibili ma le macro che assomigliano
+a delle funzioni possono essere scritte in minuscolo.
+
+Generalmente, le funzioni inline sono preferibili rispetto alle macro che
+sembrano funzioni.
+
+Le macro che contengono più istruzioni dovrebbero essere sempre chiuse in un
+blocco do - while:
+
+.. code-block:: c
+
+ #define macrofun(a, b, c) \
+ do { \
+ if (a == 5) \
+ do_this(b, c); \
+ } while (0)
+
+Cose da evitare quando si usano le macro:
+
+1) le macro che hanno effetti sul flusso del codice:
+
+.. code-block:: c
+
+ #define FOO(x) \
+ do { \
+ if (blah(x) < 0) \
+ return -EBUGGERED; \
+ } while (0)
+
+sono **proprio** una pessima idea. Sembra una chiamata a funzione ma termina
+la funzione chiamante; non cercate di rompere il decodificatore interno di
+chi legge il codice.
+
+2) le macro che dipendono dall'uso di una variabile locale con un nome magico:
+
+.. code-block:: c
+
+ #define FOO(val) bar(index, val)
+
+potrebbe sembrare una bella cosa, ma è dannatamente confusionario quando uno
+legge il codice e potrebbe romperlo con una cambiamento che sembra innocente.
+
+3) le macro con argomenti che sono utilizzati come l-values; questo potrebbe
+ritorcervisi contro se qualcuno, per esempio, trasforma FOO in una funzione
+inline.
+
+4) dimenticatevi delle precedenze: le macro che definiscono espressioni devono
+essere racchiuse fra parentesi. State attenti a problemi simili con le macro
+parametrizzate.
+
+.. code-block:: c
+
+ #define CONSTANT 0x4000
+ #define CONSTEXP (CONSTANT | 3)
+
+5) collisione nello spazio dei nomi quando si definisce una variabile locale in
+una macro che sembra una funzione:
+
+.. code-block:: c
+
+ #define FOO(x) \
+ ({ \
+ typeof(x) ret; \
+ ret = calc_ret(x); \
+ (ret); \
+ })
+
+ret è un nome comune per una variabile locale - __foo_ret difficilmente
+andrà in conflitto con una variabile già esistente.
+
+Il manuale di cpp si occupa esaustivamente delle macro. Il manuale di sviluppo
+di gcc copre anche l'RTL che viene usato frequentemente nel kernel per il
+linguaggio assembler.
+
+13) Visualizzare i messaggi del kernel
+--------------------------------------
+
+Agli sviluppatori del kernel piace essere visti come dotti. Tenete un occhio
+di riguardo per l'ortografia e farete una belle figura. In inglese, evitate
+l'uso di parole mozzate come ``dont``: usate ``do not`` oppure ``don't``.
+Scrivete messaggi concisi, chiari, e inequivocabili.
+
+I messaggi del kernel non devono terminare con un punto fermo.
+
+Scrivere i numeri fra parentesi (%d) non migliora alcunché e per questo
+dovrebbero essere evitati.
+
+Ci sono alcune macro per la diagnostica in <linux/device.h> che dovreste
+usare per assicurarvi che i messaggi vengano associati correttamente ai
+dispositivi e ai driver, e che siano etichettati correttamente: dev_err(),
+dev_warn(), dev_info(), e così via. Per messaggi che non sono associati ad
+alcun dispositivo, <linux/printk.h> definisce pr_info(), pr_warn(), pr_err(),
+eccetera.
+
+Tirar fuori un buon messaggio di debug può essere una vera sfida; e quando
+l'avete può essere d'enorme aiuto per risolvere problemi da remoto.
+Tuttavia, i messaggi di debug sono gestiti differentemente rispetto agli
+altri. Le funzioni pr_XXX() stampano incondizionatamente ma pr_debug() no;
+essa non viene compilata nella configurazione predefinita, a meno che
+DEBUG o CONFIG_DYNAMIC_DEBUG non vengono impostati. Questo vale anche per
+dev_dbg() e in aggiunta VERBOSE_DEBUG per aggiungere i messaggi dev_vdbg().
+
+Molti sottosistemi hanno delle opzioni di debug in Kconfig che aggiungono
+-DDEBUG nei corrispettivi Makefile, e in altri casi aggiungono #define DEBUG
+in specifici file. Infine, quando un messaggio di debug dev'essere stampato
+incondizionatamente, per esempio perché siete già in una sezione di debug
+racchiusa in #ifdef, potete usare printk(KERN_DEBUG ...).
+
+14) Assegnare memoria
+---------------------
+
+Il kernel fornisce i seguenti assegnatori ad uso generico:
+kmalloc(), kzalloc(), kmalloc_array(), kcalloc(), vmalloc(), e vzalloc().
+Per maggiori informazioni, consultate la documentazione dell'API.
+
+Il modo preferito per passare la dimensione di una struttura è il seguente:
+
+.. code-block:: c
+
+ p = kmalloc(sizeof(*p), ...);
+
+La forma alternativa, dove il nome della struttura viene scritto interamente,
+peggiora la leggibilità e introduce possibili bachi quando il tipo di
+puntatore cambia tipo ma il corrispondente sizeof non viene aggiornato.
+
+Il valore di ritorno è un puntatore void, effettuare un cast su di esso è
+ridondante. La conversione fra un puntatore void e un qualsiasi altro tipo
+di puntatore è garantito dal linguaggio di programmazione C.
+
+Il modo preferito per assegnare un vettore è il seguente:
+
+.. code-block:: c
+
+ p = kmalloc_array(n, sizeof(...), ...);
+
+Il modo preferito per assegnare un vettore a zero è il seguente:
+
+.. code-block:: c
+
+ p = kcalloc(n, sizeof(...), ...);
+
+Entrambe verificano la condizione di overflow per la dimensione
+d'assegnamento n * sizeof(...), se accade ritorneranno NULL.
+
+15) Il morbo inline
+-------------------
+
+Sembra che ci sia la percezione errata che gcc abbia una qualche magica
+opzione "rendimi più veloce" chiamata ``inline``. In alcuni casi l'uso di
+inline è appropriato (per esempio in sostituzione delle macro, vedi
+capitolo 12), ma molto spesso non lo è. L'uso abbondante della parola chiave
+inline porta ad avere un kernel più grande, che si traduce in un sistema nel
+suo complesso più lento per via di una cache per le istruzioni della CPU più
+grande e poi semplicemente perché ci sarà meno spazio disponibile per una
+pagina di cache. Pensateci un attimo; una fallimento nella cache causa una
+ricerca su disco che può tranquillamente richiedere 5 millisecondi. Ci sono
+TANTI cicli di CPU che potrebbero essere usati in questi 5 millisecondi.
+
+Spesso le persone dicono che aggiungere inline a delle funzioni dichiarate
+static e utilizzare una sola volta è sempre una scelta vincente perché non
+ci sono altri compromessi. Questo è tecnicamente vero ma gcc è in grado di
+trasformare automaticamente queste funzioni in inline; i problemi di
+manutenzione del codice per rimuovere gli inline quando compare un secondo
+utente surclassano il potenziale vantaggio nel suggerire a gcc di fare una
+cosa che avrebbe fatto comunque.
+
+16) Nomi e valori di ritorno delle funzioni
+-------------------------------------------
+
+Le funzioni possono ritornare diversi tipi di valori, e uno dei più comuni
+è quel valore che indica se una funzione ha completato con successo o meno.
+Questo valore può essere rappresentato come un codice di errore intero
+(-Exxx = fallimento, 0 = successo) oppure un booleano di successo
+(0 = fallimento, non-zero = successo).
+
+Mischiare questi due tipi di rappresentazioni è un terreno fertile per
+i bachi più insidiosi. Se il linguaggio C includesse una forte distinzione
+fra gli interi e i booleani, allora il compilatore potrebbe trovare questi
+errori per conto nostro ... ma questo non c'è. Per evitare di imbattersi
+in questo tipo di baco, seguite sempre la seguente convenzione::
+
+ Se il nome di una funzione è un'azione o un comando imperativo,
+ essa dovrebbe ritornare un codice di errore intero. Se il nome
+ è un predicato, la funzione dovrebbe ritornare un booleano di
+ "successo"
+
+Per esempio, ``add work`` è un comando, e la funzione add_work() ritorna 0
+in caso di successo o -EBUSY in caso di fallimento. Allo stesso modo,
+``PCI device present`` è un predicato, e la funzione pci_dev_present() ritorna
+1 se trova il dispositivo corrispondente con successo, altrimenti 0.
+
+Tutte le funzioni esportate (EXPORT) devono rispettare questa convenzione, e
+così dovrebbero anche tutte le funzioni pubbliche. Le funzioni private
+(static) possono non seguire questa convenzione, ma è comunque raccomandato
+che lo facciano.
+
+Le funzioni il cui valore di ritorno è il risultato di una computazione,
+piuttosto che l'indicazione sul successo di tale computazione, non sono
+soggette a questa regola. Solitamente si indicano gli errori ritornando un
+qualche valore fuori dai limiti. Un tipico esempio è quello delle funzioni
+che ritornano un puntatore; queste utilizzano NULL o ERR_PTR come meccanismo
+di notifica degli errori.
+
+17) L'uso di bool
+-----------------
+
+Nel kernel Linux il tipo bool deriva dal tipo _Bool dello standard C99.
+Un valore bool può assumere solo i valori 0 o 1, e implicitamente o
+esplicitamente la conversione a bool converte i valori in vero (*true*) o
+falso (*false*). Quando si usa un tipo bool il costrutto !! non sarà più
+necessario, e questo va ad eliminare una certa serie di bachi.
+
+Quando si usano i valori booleani, dovreste utilizzare le definizioni di true
+e false al posto dei valori 1 e 0.
+
+Per il valore di ritorno delle funzioni e per le variabili sullo stack, l'uso
+del tipo bool è sempre appropriato. L'uso di bool viene incoraggiato per
+migliorare la leggibilità e spesso è molto meglio di 'int' nella gestione di
+valori booleani.
+
+Non usate bool se per voi sono importanti l'ordine delle righe di cache o
+la loro dimensione; la dimensione e l'allineamento cambia a seconda
+dell'architettura per la quale è stato compilato. Le strutture che sono state
+ottimizzate per l'allineamento o la dimensione non dovrebbero usare bool.
+
+Se una struttura ha molti valori true/false, considerate l'idea di raggrupparli
+in un intero usando campi da 1 bit, oppure usate un tipo dalla larghezza fissa,
+come u8.
+
+Come per gli argomenti delle funzioni, molti valori true/false possono essere
+raggruppati in un singolo argomento a bit denominato 'flags'; spesso 'flags' è
+un'alternativa molto più leggibile se si hanno valori costanti per true/false.
+
+Detto ciò, un uso parsimonioso di bool nelle strutture dati e negli argomenti
+può migliorare la leggibilità.
+
+18) Non reinventate le macro del kernel
+---------------------------------------
+
+Il file di intestazione include/linux/kernel.h contiene un certo numero
+di macro che dovreste usare piuttosto che implementarne una qualche variante.
+Per esempio, se dovete calcolare la lunghezza di un vettore, sfruttate la
+macro:
+
+.. code-block:: c
+
+ #define ARRAY_SIZE(x) (sizeof(x) / sizeof((x)[0]))
+
+Analogamente, se dovete calcolare la dimensione di un qualche campo di una
+struttura, usate
+
+.. code-block:: c
+
+ #define FIELD_SIZEOF(t, f) (sizeof(((t*)0)->f))
+
+Ci sono anche le macro min() e max() che, se vi serve, effettuano un controllo
+rigido sui tipi. Sentitevi liberi di leggere attentamente questo file
+d'intestazione per scoprire cos'altro è stato definito che non dovreste
+reinventare nel vostro codice.
+
+19) Linee di configurazione degli editor e altre schifezze
+-----------------------------------------------------------
+
+Alcuni editor possono interpretare dei parametri di configurazione integrati
+nei file sorgenti e indicati con dai marcatori speciali. Per esempio, emacs
+interpreta le linee marcate nel seguente modo:
+
+.. code-block:: c
+
+ -*- mode: c -*-
+
+O come queste:
+
+.. code-block:: c
+
+ /*
+ Local Variables:
+ compile-command: "gcc -DMAGIC_DEBUG_FLAG foo.c"
+ End:
+ */
+
+Vim interpreta i marcatori come questi:
+
+.. code-block:: c
+
+ /* vim:set sw=8 noet */
+
+Non includete nessuna di queste cose nei file sorgenti. Le persone hanno le
+proprie configurazioni personali per l'editor, e i vostri sorgenti non
+dovrebbero sovrascrivergliele. Questo vale anche per i marcatori
+d'indentazione e di modalità d'uso. Le persone potrebbero aver configurato una
+modalità su misura, oppure potrebbero avere qualche altra magia per far
+funzionare bene l'indentazione.
+
+20) Inline assembly
+-------------------
+
+Nel codice specifico per un'architettura, potreste aver bisogno di codice
+*inline assembly* per interfacciarvi col processore o con una funzionalità
+specifica della piattaforma. Non esitate a farlo quando è necessario.
+Comunque, non usatele gratuitamente quando il C può fare la stessa cosa.
+Potete e dovreste punzecchiare l'hardware in C quando è possibile.
+
+Considerate la scrittura di una semplice funzione che racchiude pezzi comuni
+di codice assembler piuttosto che continuare a riscrivere delle piccole
+varianti. Ricordatevi che l' *inline assembly* può utilizzare i parametri C.
+
+Il codice assembler più corposo e non banale dovrebbe andare nei file .S,
+coi rispettivi prototipi C definiti nei file d'intestazione. I prototipi C
+per le funzioni assembler dovrebbero usare ``asmlinkage``.
+
+Potreste aver bisogno di marcare il vostro codice asm come volatile al fine
+d'evitare che GCC lo rimuova quando pensa che non ci siano effetti collaterali.
+Non c'è sempre bisogno di farlo, e farlo quando non serve limita le
+ottimizzazioni.
+
+Quando scrivete una singola espressione *inline assembly* contenente più
+istruzioni, mettete ognuna di queste istruzioni in una stringa e riga diversa;
+ad eccezione dell'ultima stringa/istruzione, ognuna deve terminare con ``\n\t``
+al fine di allineare correttamente l'assembler che verrà generato:
+
+.. code-block:: c
+
+ asm ("magic %reg1, #42\n\t"
+ "more_magic %reg2, %reg3"
+ : /* outputs */ : /* inputs */ : /* clobbers */);
+
+21) Compilazione sotto condizione
+---------------------------------
+
+Ovunque sia possibile, non usate le direttive condizionali del preprocessore
+(#if, #ifdef) nei file .c; farlo rende il codice difficile da leggere e da
+seguire. Invece, usate queste direttive nei file d'intestazione per definire
+le funzioni usate nei file .c, fornendo i relativi stub nel caso #else,
+e quindi chiamate queste funzioni senza condizioni di preprocessore. Il
+compilatore non produrrà alcun codice per le funzioni stub, produrrà gli
+stessi risultati, e la logica rimarrà semplice da seguire.
+
+È preferibile non compilare intere funzioni piuttosto che porzioni d'esse o
+porzioni d'espressioni. Piuttosto che mettere una ifdef in un'espressione,
+fattorizzate parte dell'espressione, o interamente, in funzioni e applicate
+la direttiva condizionale su di esse.
+
+Se avete una variabile o funzione che potrebbe non essere usata in alcune
+configurazioni, e quindi il compilatore potrebbe avvisarvi circa la definizione
+inutilizzata, marcate questa definizione come __maybe_used piuttosto che
+racchiuderla in una direttiva condizionale del preprocessore. (Comunque,
+se una variabile o funzione è *sempre* inutilizzata, rimuovetela).
+
+Nel codice, dov'è possibile, usate la macro IS_ENABLED per convertire i
+simboli Kconfig in espressioni booleane C, e quindi usatela nelle classiche
+condizioni C:
+
+.. code-block:: c
+
+ if (IS_ENABLED(CONFIG_SOMETHING)) {
+ ...
+ }
+
+Il compilatore valuterà la condizione come costante (constant-fold), e quindi
+includerà o escluderà il blocco di codice come se fosse in un #ifdef, quindi
+non ne aumenterà il tempo di esecuzione. Tuttavia, questo permette al
+compilatore C di vedere il codice nel blocco condizionale e verificarne la
+correttezza (sintassi, tipi, riferimenti ai simboli, eccetera). Quindi
+dovete comunque utilizzare #ifdef se il codice nel blocco condizionale esiste
+solo quando la condizione è soddisfatta.
+
+Alla fine di un blocco corposo di #if o #ifdef (più di alcune linee),
+mettete un commento sulla stessa riga di #endif, annotando la condizione
+che termina. Per esempio:
+
+.. code-block:: c
+
+ #ifdef CONFIG_SOMETHING
+ ...
+ #endif /* CONFIG_SOMETHING */

+Come partecipare allo sviluppo del kernel Linux
+===============================================
+
+Questo è il documento fulcro di quanto trattato sull'argomento.
+Esso contiene le istruzioni su come diventare uno sviluppatore
+del kernel Linux e spiega come lavorare con la comunità di
+sviluppo kernel Linux. Il documento non tratterà alcun aspetto
+tecnico relativo alla programmazione del kernel, ma vi aiuterà
+indirizzandovi sulla corretta strada.

+
+Introduzione
+------------
+Dunque, volete imparare come diventare sviluppatori del kernel Linux?
+O vi è stato detto dal vostro capo, "Vai, scrivi un driver Linux per
+questo dispositivo". Bene, l'obbiettivo di questo documento è quello
+di insegnarvi tutto ciò che dovete sapere per raggiungere il vostro
+scopo descrivendo il procedimento da seguire e consigliandovi
+su come lavorare con la comunità. Il documento cercherà, inoltre,
+di spiegare alcune delle ragioni per le quali la comunità lavora in un
+modo suo particolare.
+
+Il kernel è scritto prevalentemente nel linguaggio C con alcune parti
+specifiche dell'architettura scritte in linguaggio assembly.
+Per lo sviluppo kernel è richiesta una buona conoscenza del linguaggio C.
+L'assembly (di qualsiasi architettura) non è richiesto, a meno che non
+pensiate di fare dello sviluppo di basso livello per un'architettura.
+Sebbene essi non siano un buon sostituto ad un solido studio del
+linguaggio C o ad anni di esperienza, i seguenti libri sono, se non

+Il kernel è stato scritto usando GNU C e la toolchain GNU.
+Sebbene si attenga allo standard ISO C89, esso utilizza una serie di
+estensioni che non sono previste in questo standard. Il kernel è un
+ambiente C indipendente, che non ha alcuna dipendenza dalle librerie
+C standard, così alcune parti del C standard non sono supportate.
+Le divisioni ``long long`` e numeri in virgola mobile non sono permessi.
+Qualche volta è difficile comprendere gli assunti che il kernel ha
+riguardo gli strumenti e le estensioni in uso, e sfortunatamente non
+esiste alcuna indicazione definitiva. Per maggiori informazioni, controllate,
+la pagina `info gcc`.
+
+Tenete a mente che state cercando di apprendere come lavorare con la comunità
+di sviluppo già esistente. Questo è un gruppo eterogeneo di persone, con alti
+standard di codifica, di stile e di procedura. Questi standard sono stati
+creati nel corso del tempo basandosi su quanto hanno riscontrato funzionare al
+meglio per un squadra così grande e geograficamente sparsa. Cercate di
+imparare, in anticipo, il più possibile circa questi standard, poichè ben
+spiegati; non aspettatevi che gli altri si adattino al vostro modo di fare
+o a quello della vostra azienda.

+Documentazione
+--------------
+I sorgenti del kernel Linux hanno una vasta base di documenti che vi
+insegneranno come interagire con la comunità del kernel. Quando nuove
+funzionalità vengono aggiunte al kernel, si raccomanda di aggiungere anche i
+relativi file di documentatione che spiegano come usarele.
+Quando un cambiamento del kernel genera anche un cambiamento nell'interfaccia
+con lo spazio utente, è raccomandabile che inviate una notifica o una
+correzione alle pagine *man* spiegando tale modifica agli amministratori di
+queste pagine all'indirizzo mtk.manpages@gmail.com, aggiungendo
+in CC la lista linux-api@vger.kernel.org.
+
+Di seguito una lista di file che sono presenti nei sorgente del kernel e che
+è richiesto che voi leggiate:
+
+ :ref:`Documentation/translations/it_IT/admin-guide/README.rst <it_readme>`
+ Questo file da una piccola anteprima del kernel Linux e descrive il
+ minimo necessario per configurare e generare il kernel. I novizi
+ del kernel dovrebbero iniziare da qui.
+
+ :ref:`Documentation/translations/it_IT/process/changes.rst <it_changes>`
+
+ Questo file fornisce una lista dei pacchetti software necessari
+ a compilare e far funzionare il kernel con successo.
+
+ :ref:`Documentation/translations/it_IT/process/coding-style.rst <it_codingstyle>`
+
+ Questo file descrive lo stile della codifica per il kernel Linux,
+ e parte delle motivazioni che ne sono alla base. Tutto il nuovo codice deve
+ seguire le linee guida in questo documento. Molti amministratori
+ accetteranno patch solo se queste osserveranno tali regole, e molte
+ persone revisioneranno il codice solo se scritto nello stile appropriato.
+
+ :ref:`Documentation/translations/it_IT/process/submitting-patches.rst <it_submittingpatches>` e
+ :ref:`Documentation/translations/it_IT/process/submitting-drivers.rst <it_submittingdrivers>`
+
+ Questo file descrive dettagliatamente come creare ed inviare una patch
+ con successo, includendo (ma non solo questo):
+
+ - Contenuto delle email
+ - Formato delle email
+ - I destinatari delle email
+
+ Seguire tali regole non garantirà il successo (tutte le patch sono soggette
+ a controlli realitivi a contenuto e stile), ma non seguirle lo precluderà
+ sempre.
+
+ Altre ottime descrizioni di come creare buone patch sono:
+
+ "The Perfect Patch"
+ https://www.ozlabs.org/~akpm/stuff/tpp.txt
+
+ "Linux kernel patch submission format"
+ http://linux.yyz.us/patch-format.html
+
+ :ref:`Documentation/process/translations/it_IT/stable-api-nonsense.rst <it_stable_api_nonsense>`
+
+ Questo file descrive la motivazioni sottostanti la conscia decisione di
+ non avere un API stabile all'interno del kernel, incluso cose come:
+
+ - Sottosistemi shim-layers (per compatibilità?)
+ - Portabilità fra Sistemi Operativi dei driver.
+ - Attenuare i rapidi cambiamenti all'interno dei sorgenti del kernel
+ (o prevenirli)
+
+ Questo documento è vitale per la comprensione della filosifia alla base
+ dello sviluppo di Linux ed è molto importante per le persone che arrivano
+ da esperienze con altri Sistemi Operativi.
+
+ :ref:`Documentation/translations/it_IT/admin-guide/security-bugs.rst <it_securitybugs>`
+ Se ritenete di aver trovato un problema di sicurezza nel kernel Linux,
+ seguite i passaggi scritti in questo documento per notificarlo agli
+ sviluppatori del kernel, ed aiutare la risoluzione del problema.
+
+ :ref:`Documentation/translations/it_IT/process/management-style.rst <it_managementstyle>`
+ Questo documento descrive come i manutentori del kernel Linux operano
+ e la filosofia comune alla base del loro metodo. Questa è un'importante
+ lettura per tutti coloro che sono nuovi allo sviluppo del kernel (o per
+ chi è semplicemente curioso), poiché risolve molti dei più comuni
+ fraintendimenti e confusioni dovuti al particolare comportamento dei
+ manutentori del kernel.

+
+ :ref:`Documentation/translations/it_IT/process/applying-patches.rst <it_applying_patches>`
+ Una buona introduzione che descrivere esattamente cos'è una patch e come
+ applicarla ai differenti rami di sviluppo del kernel.
+
+Il kernel inoltre ha un vasto numero di documenti che possono essere
+automaticamente generati dal codice sorgente stesso o da file
+ReStructuredText (ReST), come questo. Esso include una completa
+descrizione dell'API interna del kernel, e le regole su come gestire la
+sincronizzazione (locking) correttamente
+
+Tutte queste tipologie di documenti possono essere generati in PDF o in
+HTML utilizzando::
+
+ make pdfdocs
+ make htmldocs
+
+rispettivamente dalla cartella principale dei sorgenti del kernel.
+
+I documenti che impiegano ReST saranno generati nella cartella
+Documentation/output.
+Questi posso essere generati anche in formato LaTex e ePub con::
+
+ make latexdocs
+ make epubdocs
+
+Diventare uno sviluppatore del kernel
+-------------------------------------
+Se non sapete nulla sullo sviluppo del kernel Linux, dovreste dare uno
+sguardo al progetto *Linux KernelNewbies*:
+
+ https://kernelnewbies.org
+
+Esso prevede un'utile lista di discussione dove potete porre più o meno ogni
+tipo di quesito relativo ai concetti fondamentali sullo sviluppo del kernel
+(assicuratevi di cercare negli archivi, prima di chiedere qualcosa alla
+quale è già stata fornita risposta in passato). Esistono inoltre, un canale IRC
+che potete usare per formulare domande in tempo reale, e molti documenti utili
+che vi faciliteranno nell'apprendimento dello sviluppo del kernel Linux.
+
+Il sito internet contiene informazioni di base circa l'organizzazione del
+codice, sottosistemi e progetti attuali (sia interni che esterni a Linux).
+Esso descrive, inoltre, informazioni logistiche di base, riguardanti ad esempio
+la compilazione del kernel e l'applicazione di una modifica.
+
+Se non sapete dove cominciare, ma volete cercare delle attività dalle quali
+partire per partecipare alla comunità di sviluppo, andate al progetto Linux
+Kernel Janitor's.
+
+ https://kernelnewbies.org/KernelJanitors
+
+È un buon posto da cui iniziare. Esso presenta una lista di problematiche
+relativamente semplici da sistemare e pulire all'interno della sorgente del
+kernel Linux. Lavorando con gli sviluppatori incaricati di questo progetto,
+imparerete le basi per l'inserimento delle vostre modifiche all'interno dei
+sorgenti del kernel Linux, e possibilmente, sarete indirizzati al lavoro
+successivo da svolgere, se non ne avrete ancora idea.
+
+Prima di apportare una qualsiasi modifica al codice del kernel Linux,
+è imperativo comprendere come tale codice funziona. A questo scopo, non c'è
+nulla di meglio che leggerlo direttamente (la maggior parte dei bit più
+complessi sono ben commentati), eventualmente anche con l'aiuto di strumenti
+specializzati. Uno degli strumenti che è particolarmente raccomandato è
+il progetto Linux Cross-Reference, che è in grado di presentare codice
+sorgente in un formato autoreferenziale ed indicizzato. Un eccellente ed
+aggiornata fonte di consultazione del codice del kernel la potete trovare qui:
+
+ https://elixir.bootlin.com/
+
+
+Il processo di sviluppo
+-----------------------
+Il processo di sviluppo del kernel Linux si compone di pochi "rami" principali
+e di molti altri rami per specifici sottosistemi. Questi rami sono:
+
+ - I sorgenti kernel 4.x
+ - I sorgenti stabili del kernel 4.x.y -stable
+ - Sorgenti dei sottosistemi del kernel e le loro modifiche
+ - Il kernel 4.x -next per test d'integrazione
+
+I sorgenti kernel 4.x
+~~~~~~~~~~~~~~~~~~~~~
+
+I kernel 4.x sono amministrati da Linus Torvald, e possono essere trovati
+su https://kernel.org nella cartella pub/linux/kernel/v4.x/. Il processo
+di sviluppo è il seguente:
+
+ - Non appena un nuovo kernel viene rilasciato si apre una finestra di due
+ settimane. Durante questo periodo i manutentori possono proporre a Linus
+ dei grossi cambiamenti; solitamente i cambiamenti che sono già stati
+ inseriti nel ramo -next del kernel per alcune settimane. Il modo migliore
+ per sottoporre dei cambiamenti è attraverso git (lo strumento usato per
+ gestire i sorgenti del kernel, più informazioni sul sito
+ https://git-scm.com/) ma anche delle patch vanno bene.
+
+ - Al termine delle due settimane un kernel -rc1 viene rilasciato e
+ l'obbiettivo ora è quello di renderlo il più solido possibile. A questo
+ punto la maggior parte delle patch dovrebbero correggere un'eventuale
+ regressione. I bachi che sono sempre esistiti non sono considerabili come
+ regressioni, quindi inviate questo tipo di cambiamenti solo se sono
+ importanti. Notate che un intero driver (o filesystem) potrebbe essere
+ accettato dopo la -rc1 poiché non esistono rischi di una possibile
+ regressione con tale cambiamento, fintanto che quest'ultimo è
+ auto-contenuto e non influisce su aree esterne al codice che è stato
+ aggiunto. git può essere utilizzato per inviare le patch a Linus dopo che
+ la -rc1 è stata rilasciata, ma è anche necessario inviare le patch ad
+ una lista di discussione pubblica per un'ulteriore revisione.
+
+ - Una nuova -rc viene rilasciata ogni volta che Linus reputa che gli attuali
+ sorgenti siano in uno stato di salute ragionevolmente adeguato ai test.
+ L'obiettivo è quello di rilasciare una nuova -rc ogni settimana.
+
+ - Il processo continua fino a che il kernel è considerato "pronto"; tale
+ processo dovrebbe durare circa in 6 settimane.
+
+È utile menzionare quanto scritto da Andrew Morton sulla lista di discussione
+kernel-linux in merito ai rilasci del kernel:
+
+ *"Nessuno sa quando un kernel verrà rilasciato, poichè questo è
+ legato allo stato dei bachi e non ad una cronologia preventiva."*
+
+I sorgenti stabili del kernel 4.x.y -stable
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+I kernel con versioni in 3-parti sono "kernel stabili". Essi contengono
+correzioni critiche relativamente piccole nell'ambito della sicurezza
+oppure significative regressioni scoperte in un dato 4.x kernel.
+
+Questo è il ramo raccomandato per gli utenti che vogliono un kernel recente
+e stabile e non sono interessati a dare il proprio contributo alla verifica
+delle versioni di sviluppo o sperimentali.
+
+Se non è disponibile alcun kernel 4.x.y., quello più aggiornato e stabile
+sarà il kernel 4.x con la numerazione più alta.
+
+4.x.y sono amministrati dal gruppo "stable" <stable@vger.kernel.org>, e sono
+rilasciati a seconda delle esigenze. Il normale periodo di rilascio è
+approssimativamente di due settimane, ma può essere più lungo se non si
+verificano problematiche urgenti. Un problema relativo alla sicurezza, invece,
+può determinare un rilascio immediato.
+
+Il file Documentation/process/stable-kernel-rules.rst (nei sorgenti) documenta
+quali tipologie di modifiche sono accettate per i sorgenti -stable, e come
+avviene il processo di rilascio.
+
+
+Sorgenti dei sottosistemi del kernel e le loro patch
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+I manutentori dei diversi sottosistemi del kernel --- ed anche molti
+sviluppatori di sottosistemi --- mostrano il loro attuale stato di sviluppo
+nei loro repositori. In questo modo, altri possono vedere cosa succede nelle
+diverse parti del kernel. In aree dove lo sviluppo è rapido, potrebbe essere
+chiesto ad uno sviluppatore di basare le proprie modifiche su questi repositori
+in modo da evitare i conflitti fra le sottomissioni ed altri lavori in corso
+
+La maggior parte di questi repositori sono git, ma esistono anche altri SCM
+in uso, o file di patch pubblicate come una serie quilt.
+Gli indirizzi dei repositori di sottosistema sono indicati nel file
+MAINTAINERS. Molti di questi posso essere trovati su https://git.kernel.org/.
+
+Prima che una modifica venga inclusa in questi sottosistemi, sarà soggetta ad
+una revisione che inizialmente avviene tramite liste di discussione (vedere la
+sezione dedicata qui sotto). Per molti sottosistemi del kernel, tale processo
+di revisione è monitorato con lo strumento patchwork.
+Patchwork offre un'interfaccia web che mostra le patch pubblicate, inclusi i
+commenti o le revisioni fatte, e gli amministratori possono indicare le patch
+come "in revisione", "accettate", o "rifiutate". Diversi siti Patchwork sono
+elencati al sito https://patchwork.kernel.org/.
+
+Il kernel 4.x -next per test d'integrazione
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Prima che gli aggiornamenti dei sottosistemi siano accorpati nel ramo
+principale 4.x, sarà necessario un test d'integrazione.
+A tale scopo, esiste un repositorio speciale di test nel quale virtualmente
+tutti i rami dei sottosistemi vengono inclusi su base quotidiana:
+
+ https://git.kernel.org/?p=linux/kernel/git/next/linux-next.git
+
+In questo modo, i kernel -next offrono uno sguardo riassuntivo su quello che
+ci si aspetterà essere nel kernel principale nel successivo periodo
+d'incorporazione.
+Coloro che vorranno fare dei test d'esecuzione del kernel -next sono più che
+benvenuti.
+
+
+Riportare Bug
+-------------
+
+https://bugzilla.kernel.org è dove gli sviluppatori del kernel Linux tracciano
+i bachi del kernel. Gli utenti sono incoraggiati nel riportare tutti i bachi
+che trovano utilizzando questo strumento.
+Per maggiori dettagli su come usare il bugzilla del kernel, guardare:
+
+ https://bugzilla.kernel.org/page.cgi?id=faq.html
+
+Il file admin-guide/reporting-bugs.rst nella cartella principale del kernel
+fornisce un buon modello sul come segnalare un baco nel kernel, e spiega quali
+informazioni sono necessarie agli sviluppatori per poter aiutare il
+rintracciamento del problema.
+
+Gestire i rapporti sui bug
+--------------------------
+
+Uno dei modi migliori per mettere in pratica le vostre capacità di hacking è
+quello di riparare bachi riportati da altre persone. Non solo aiuterete a far
+diventare il kernel più stabile, ma imparerete a riparare problemi veri dal
+mondo ed accrescerete le vostre competenze, e gli altri sviluppatori saranno
+al corrente della vostra presenza. Riparare bachi è una delle migliori vie per
+acquisire meriti tra gli altri sviluppatori, perchè non a molte persone piace
+perdere tempo a sistemare i bachi di altri.
+
+Per lavorare sui rapporti di bachi già riportati, andate su
+https://bugzilla.kernel.org.
+
+Liste di discussione
+--------------------
+
+Come descritto in molti dei documenti qui sopra, la maggior parte degli
+sviluppatori del kernel partecipano alla lista di discussione Linux Kernel.
+I dettagli su come iscriversi e disiscriversi dalla lista possono essere
+trovati al sito:
+
+ http://vger.kernel.org/vger-lists.html#linux-kernel
+
+Ci sono diversi archivi della lista di discussione. Usate un qualsiasi motore
+di ricerca per trovarli. Per esempio:
+
+ http://dir.gmane.org/gmane.linux.kernel
+
+É caldamente consigliata una ricerca in questi archivi sul tema che volete
+sollevare, prima di pubblicarlo sulla lista. Molte cose sono già state
+discusse in dettaglio e registrate negli archivi della lista di discussione.
+
+Molti dei sottosistemi del kernel hanno anche una loro lista di discussione
+dedicata. Guardate nel file MAINTAINERS per avere una lista delle liste di
+discussione e il loro uso.
+
+Molte di queste liste sono gestite su kernel.org. Per informazioni consultate
+la seguente pagina:
+
+ http://vger.kernel.org/vger-lists.html
+
+Per favore ricordatevi della buona educazione quando utilizzate queste liste.
+Sebbene sia un pò dozzinale, il seguente URL contiene alcune semplici linee
+guida per interagire con la lista (o con qualsiasi altra lista):
+
+ http://www.albion.com/netiquette/
+
+Se diverse persone rispondo alla vostra mail, la lista dei riceventi (copia
+conoscenza) potrebbe diventare abbastanza lunga. Non cancellate nessuno dalla
+lista di CC: senza un buon motivo, e non rispondete solo all'indirizzo
+della lista di discussione. Fateci l'abitudine perché capita spesso di
+ricevere la stessa email due volte: una dal mittente ed una dalla lista; e non
+cercate di modificarla aggiungendo intestazioni stravaganti, agli altri non
+piacerà.
+
+Ricordate di rimanere sempre in argomento e di mantenere le attribuzioni
+delle vostre risposte invariate; mantenete il "John Kernelhacker wrote ...:"
+in cima alla vostra replica e aggiungete le vostre risposte fra i singoli
+blocchi citati, non scrivete all'inizio dell'email.
+
+Se aggiungete patch alla vostra mail, assicuratevi che siano del tutto
+leggibili come indicato in Documentation/process/submitting-patches.rst.
+Gli sviluppatori kernel non vogliono avere a che fare con allegati o patch
+compresse; vogliono invece poter commentare le righe dei vostri cambiamenti,
+il che può funzionare solo in questo modo.
+Assicuratevi di utilizzare un gestore di mail che non alterì gli spazi ed i
+caratteri. Un ottimo primo test è quello di inviare a voi stessi una mail e
+cercare di sottoporre la vostra stessa patch. Se non funziona, sistemate il
+vostro programma di posta, o cambiatelo, finché non funziona.
+
+Ed infine, per favore ricordatevi di mostrare rispetto per gli altri
+sottoscriventi.
+
+Lavorare con la comunità
+------------------------
+
+L'obiettivo di questa comunità è quello di fornire il miglior kernel possibile.
+Quando inviate una modifica che volete integrare, sarà valutata esclusivamente
+dal punto di vista tecnico. Quindi, cosa dovreste aspettarvi?
+
+ - critiche
+ - commenti
+ - richieste di cambiamento
+ - richieste di spiegazioni
+ - nulla
+
+Ricordatevi che questo fa parte dell'integrazione della vostra modifica
+all'interno del kernel. Dovete essere in grado di accettare le critiche,
+valutarle a livello tecnico ed eventualmente rielaborare nuovamente le vostre
+modifiche o fornire delle chiare e concise motivazioni per le quali le
+modifiche suggerite non dovrebbero essere fatte.
+Se non riceverete risposte, aspettate qualche giorno e riprovate ancora,
+qualche volta le cose si perdono nell'enorme mucchio di email.
+
+Cosa non dovreste fare?
+
+ - aspettarvi che la vostra modifica venga accettata senza problemi
+ - mettervi sulla difensiva
+ - ignorare i commenti
+ - sottomettere nuovamente la modifica senza fare nessuno dei cambiamenti
+ richiesti
+
+In una comunità che è alla ricerca delle migliori soluzioni tecniche possibili,
+ci saranno sempre opinioni differenti sull'utilità di una modifica.
+Siate cooperativi e vogliate adattare la vostra idea in modo che sia inserita
+nel kernel. O almeno vogliate dimostrare che la vostra idea vale.
+Ricordatevi, sbagliare è accettato fintanto che siate disposti a lavorare verso
+una soluzione che è corretta.
+
+È normale che le risposte alla vostra prima modifica possa essere
+semplicemente una lista con dozzine di cose che dovreste correggere.
+Questo **non** implica che la vostra patch non sarà accettata, e questo
+**non** è contro di voi personalmente.
+Semplicemente correggete tutte le questioni sollevate contro la vostra modifica
+ed inviatela nuovamente.
+
+Differenze tra la comunità del kernel e le strutture aziendali
+--------------------------------------------------------------
+
+La comunità del kernel funziona diversamente rispetto a molti ambienti di
+sviluppo aziendali. Qui di seguito una lista di cose che potete provare a
+fare per evitare problemi:
+
+ Cose da dire riguardanti le modifiche da voi proposte:
+
+ - "Questo risolve più problematiche."
+ - "Questo elimina 2000 stringhe di codice."
+ - "Qui una modifica che spiega cosa sto cercando di fare."
+ - "L'ho testato su 5 diverse architetture.."
+ - "Qui una serie di piccole modifiche che.."
+ - "Questo aumenta le prestazioni di macchine standard..."
+
+ Cose che dovreste evitare di dire:
+
+ - "Lo abbiamo fatto in questo modo in AIX/ptx/Solaris, di conseguenza
+ deve per forza essere giusto..."
+ - "Ho fatto questo per 20 anni, quindi.."
+ - "Questo è richiesto dalla mia Azienda per far soldi"
+ - "Questo è per la linea di prodotti della nostra Azienda"
+ - "Ecco il mio documento di design di 1000 pagine che descrive ciò che ho
+ in mente"
+ - "Ci ho lavorato per 6 mesi..."
+ - "Ecco una patch da 5000 righe che.."
+ - "Ho riscritto il pasticcio attuale, ed ecco qua.."
+ - "Ho una scadenza, e questa modifica ha bisogno di essere approvata ora"
+
+Un'altra cosa nella quale la comunità del kernel si differenzia dai più
+classici ambienti di ingegneria del software è la natura "senza volto" delle
+interazioni umane. Uno dei benefici dell'uso delle email e di irc come forma
+primordiale di comunicazione è l'assenza di discriminazione basata su genere e
+razza. L'ambienti di lavoro Linux accetta donne e minoranze perchè tutto quello
+che sei è un indirizzo email. Aiuta anche l'aspetto internazionale nel
+livellare il terreno di gioco perchè non è possibile indovinare il genere
+basandosi sul nome di una persona. Un uomo può chiamarsi Andrea ed una donna
+potrebbe chiamarsi Pat. Gran parte delle donne che hanno lavorato al kernel
+Linux e che hanno espresso una personale opinione hanno avuto esperienze
+positive.
+
+La lingua potrebbe essere un ostacolo per quelle persone che non si trovano
+a loro agio con l'inglese. Una buona padronanza del linguaggio può essere
+necessaria per esporre le proprie idee in maniera appropiata all'interno
+delle liste di discussione, quindi è consigliabile che rileggiate le vostre
+email prima di inviarle in modo da essere certi che abbiano senso in inglese.
+
+
+Spezzare le vostre modifiche
+----------------------------
+
+La comunità del kernel Linux non accetta con piacere grossi pezzi di codice
+buttati lì tutti in una volta. Le modifiche necessitano di essere
+adeguatamente presentate, discusse, e suddivise in parti più piccole ed
+indipendenti. Questo è praticamente l'esatto opposto di quello che le
+aziende fanno solitamente. La vostra proposta dovrebbe, inoltre, essere
+presentata prestissimo nel processo di sviluppo, così che possiate ricevere
+un riscontro su quello che state facendo. Lasciate che la comunità
+senta che state lavorando con loro, e che non li stiate sfruttando come
+discarica per le vostre aggiunte. In ogni caso, non inviate 50 email nello
+stesso momento in una lista di discussione, il più delle volte la vostra serie
+di modifiche dovrebbe essere più piccola.
+
+I motivi per i quali dovreste frammentare le cose sono i seguenti:
+
+1) Piccole modifiche aumentano le probabilità che vengano accettate,
+ altrimenti richiederebbe troppo tempo o sforzo nel verificarne
+ la correttezza. Una modifica di 5 righe può essere accettata da un
+ manutentore con a mala pena una seconda occhiata. Invece, una modifica da
+ 500 linee può richiedere ore di rilettura per verificarne la correttezza
+ (il tempo necessario è esponenzialmente proporzionale alla dimensione della
+ modifica, o giù di lì)
+
+ Piccole modifiche sono inoltre molto facili da debuggare quando qualcosa
+ non va. È molto più facile annullare le modifiche una per una che
+ dissezionare una patch molto grande dopo la sua sottomissione (e rompere
+ qualcosa).
+
+2) È importante non solo inviare piccole modifiche, ma anche riscriverle e
+ semplificarle (o più semplicemente ordinarle) prima di sottoporle.
+
+Qui un'analogia dello sviluppatore kernel Al Viro:
+
+ *"Pensate ad un insegnante di matematica che corregge il compito
+ di uno studente (di matematica). L'insegnante non vuole vedere le
+ prove e gli errori commessi dallo studente prima che arrivi alla
+ soluzione. Vuole vedere la risposta più pulita ed elegante
+ possibile. Un buono studente lo sa, e non presenterebbe mai le
+ proprie bozze prima prima della soluzione finale"*
+
+ *"Lo stesso vale per lo sviluppo del kernel. I manutentori ed i
+ revisori non vogliono vedere il procedimento che sta dietro al
+ problema che uno sta risolvendo. Vogliono vedere una soluzione
+ semplice ed elegante."*
+
+Può essere una vera sfida il saper mantenere l'equilibrio fra una presentazione
+elegante della vostra soluzione, lavorare insieme ad una comunità e dibattere
+su un lavoro incompleto. Pertanto è bene entrare presto nel processo di
+revisione per migliorare il vostro lavoro, ma anche per riuscire a tenere le
+vostre modifiche in pezzettini che potrebbero essere già accettate, nonostante
+la vostra intera attività non lo sia ancora.
+
+In fine, rendetevi conto che non è accettabile inviare delle modifiche
+incomplete con la promessa che saranno "sistemate dopo".
+
+
+Giustificare le vostre modifiche
+--------------------------------
+
+Insieme alla frammentazione delle vostre modifiche, è altrettanto importante
+permettere alla comunità Linux di capire perché dovrebbero accettarle.
+Nuove funzionalità devono essere motivate come necessarie ed utili.
+
+
+Documentare le vostre modifiche
+-------------------------------
+
+Quando inviate le vostre modifiche, fate particolare attenzione a quello che
+scrivete nella vostra email. Questa diventerà il *ChangeLog* per la modifica,
+e sarà visibile a tutti per sempre. Dovrebbe descrivere la modifica nella sua
+interezza, contenendo:
+
+ - perchè la modifica è necessaria
+ - l'approccio d'insieme alla patch
+ - dettagli supplementari
+ - risultati dei test
+
+Per maggiori dettagli su come tutto ciò dovrebbe apparire, riferitevi alla
+sezione ChangeLog del documento:
+
+ "The Perfect Patch"
+ http://www.ozlabs.org/~akpm/stuff/tpp.txt
+
+A volte tutto questo è difficile da realizzare. Il perfezionamento di queste
+pratiche può richiedere anni (eventualmente). È un processo continuo di
+miglioramento che richiede molta pazienza e determinazione. Ma non mollate,
+si può fare. Molti lo hanno fatto prima, ed ognuno ha dovuto iniziare dove
+siete voi ora.

+Dichiarazioni sui driver per il kernel
+======================================
+
+Presa di posizione sui moduli per il kernel Linux
+-------------------------------------------------
+
+Noi, i sottoscritti sviluppatori del kernel, consideriamo pericoloso
+o indesiderato qualsiasi modulo o driver per il kernel Linux di tipo
+*a sorgenti chiusi* (*closed-source*). Ripetutamente, li abbiamo
+trovati deleteri per gli utenti Linux, le aziende, ed in generale
+l'ecosistema Linux. Questi moduli impediscono l'apertura, la stabilità,
+la flessibilità, e la manutenibilità del modello di sviluppo di Linux
+e impediscono ai loro utenti di beneficiare dell'esperienza dalla
+comunità Linux. I fornitori che distribuiscono codice a sorgenti chiusi
+obbligano i propri utenti a rinunciare ai principali vantaggi di Linux
+o a cercarsi nuovi fornitori.
+Perciò, al fine di sfruttare i vantaggi che codice aperto ha da offrire,
+come l'abbattimento dei costi e un supporto condiviso, spingiamo i
+fornitori ad adottare una politica di supporto ai loro clienti Linux
+che preveda il rilascio dei sorgenti per il kernel.
+
+Parliamo solo per noi stessi, e non per una qualsiasi azienda per la
+quale lavoriamo oggi, o abbiamo lavorato in passato, o lavoreremo in
+futuro.

+I numeri magici di Linux
+========================
+
+Questo documento è un registro dei numeri magici in uso. Quando
+aggiungete un numero magico ad una struttura, dovreste aggiungerlo anche
+a questo documento; la cosa migliore è che tutti i numeri magici usati
+dalle varie strutture siano unici.
+
+È **davvero** un'ottima idea proteggere le strutture dati del kernel con
+dei numeri magici. Questo vi permette in fase d'esecuzione di (a) verificare
+se una struttura è stata malmenata, o (b) avete passato a una procedura la
+struttura errata. Quest'ultimo è molto utile - particolarmente quando si passa
+una struttura dati tramite un puntatore void \*. Il codice tty, per esempio,
+effettua questa operazione con regolarità passando avanti e indietro le
+strutture specifiche per driver e discipline.
+
+Per utilizzare un numero magico, dovete dichiararlo all'inizio della struttura
+dati, come di seguito::
+
+ struct tty_ldisc {
+ int magic;
+ ...
+ };
+
+Per favore, seguite questa direttiva quando aggiungerete migliorie al kernel!
+Mi ha risparmiato un numero illimitato di ore di debug, specialmente nei casi
+più ostici dove si è andati oltre la dimensione di un vettore e la struttura
+dati che lo seguiva in memoria è stata sovrascritta. Seguendo questa
+direttiva, questi casi vengono identificati velocemente e in sicurezza.

+
+ Michael Chastain
+ <mailto:mec@shout.net>
+ 22 Sep 1997
+
+ Ora dovrebbe essere aggiornata a Linux 2.1.112. Dato che

+ Aggiornamento della tabella a Linux 2.5.45. Giusti nel congelamento

+ numero magico s'intrufoli prima del kernel 2.6.x.

+L'interfaccia dei driver per il kernel Linux
+============================================
+
+(tutte le risposte alle vostre domande e altro)
+
+Greg Kroah-Hartman <greg@kroah.com>
+
+Questo è stato scritto per cercare di spiegare perché Linux **non ha
+un'interfaccia binaria, e non ha nemmeno un'interfaccia stabile**.
+
+.. note::
+
+ Questo articolo parla di interfacce **interne al kernel**, non delle
+ interfacce verso lo spazio utente.
+
+ L'interfaccia del kernel verso lo spazio utente è quella usata dai
+ programmi, ovvero le chiamate di sistema. Queste interfacce sono **molto**
+ stabili nel tempo e non verranno modificate. Ho vecchi programmi che sono
+ stati compilati su un kernel 0.9 (circa) e tuttora funzionano sulle versioni
+ 2.6 del kernel. Queste interfacce sono quelle che gli utenti e i
+ programmatori possono considerare stabili.
+
+Riepilogo generale
+------------------
+
+Pensate di volere un'interfaccia del kernel stabile, ma in realtà non la
+volete, e nemmeno sapete di non volerla. Quello che volete è un driver
+stabile che funzioni, e questo può essere ottenuto solo se il driver si trova
+nei sorgenti del kernel. Ci sono altri vantaggi nell'avere il proprio driver
+nei sorgenti del kernel, ognuno dei quali hanno reso Linux un sistema operativo
+robusto, stabile e maturo; questi sono anche i motivi per cui avete scelto
+Linux.
+
+Introduzione
+------------
+
+Solo le persone un po' strambe vorrebbero scrivere driver per il kernel con
+la costante preoccupazione per i cambiamenti alle interfacce interne. Per il
+resto del mondo, queste interfacce sono invisibili o non di particolare
+interesse.
+
+Innanzitutto, non tratterò **alcun** problema legale riguardante codice
+chiuso, nascosto, avvolto, blocchi binari, o qualsia altra cosa che descrive
+driver che non hanno i propri sorgenti rilasciati con licenza GPL. Per favore
+fate riferimento ad un avvocato per qualsiasi questione legale, io sono un
+programmatore e perciò qui vi parlerò soltanto delle questioni tecniche (non
+per essere superficiali sui problemi legali, sono veri e dovete esserne a
+conoscenza in ogni circostanza).
+
+Dunque, ci sono due tematiche principali: interfacce binarie del kernel e
+interfacce stabili nei sorgenti. Ognuna dipende dall'altra, ma discuteremo
+prima delle cose binarie per toglierle di mezzo.
+
+Interfaccia binaria del kernel
+------------------------------
+
+Supponiamo d'avere un'interfaccia stabile nei sorgenti del kernel, di
+conseguenza un'interfaccia binaria dovrebbe essere anche'essa stabile, giusto?
+Sbagliato. Prendete in considerazione i seguenti fatti che riguardano il
+kernel Linux:
+
+ - A seconda della versione del compilatore C che state utilizzando, diverse
+ strutture dati del kernel avranno un allineamento diverso, e possibilmente
+ un modo diverso di includere le funzioni (renderle inline oppure no).
+ L'organizzazione delle singole funzioni non è poi così importante, ma la
+ spaziatura (*padding*) nelle strutture dati, invece, lo è.
+
+ - In base alle opzioni che sono state selezionate per generare il kernel,
+ un certo numero di cose potrebbero succedere:
+
+ - strutture dati differenti potrebbero contenere campi differenti
+ - alcune funzioni potrebbero non essere implementate (per esempio,
+ alcuni *lock* spariscono se compilati su sistemi mono-processore)
+ - la memoria interna del kernel può essere allineata in differenti modi
+ a seconda delle opzioni di compilazione.
+
+ - Linux funziona su una vasta gamma di architetture di processore. Non esiste
+ alcuna possibilità che il binario di un driver per un'architettura funzioni
+ correttamente su un'altra.
+
+Alcuni di questi problemi possono essere risolti compilando il proprio modulo
+con la stessa identica configurazione del kernel, ed usando la stessa versione
+del compilatore usato per compilare il kernel. Questo è sufficiente se volete
+fornire un modulo per uno specifico rilascio su una specifica distribuzione
+Linux. Ma moltiplicate questa singola compilazione per il numero di
+distribuzioni Linux e il numero dei rilasci supportati da quest'ultime e vi
+troverete rapidamente in un incubo fatto di configurazioni e piattaforme
+hardware (differenti processori con differenti opzioni); dunque, anche per il
+singolo rilascio di un modulo, dovreste creare differenti versioni dello
+stesso.
+
+Fidatevi, se tenterete questa via, col tempo, diventerete pazzi; l'ho imparato
+a mie spese molto tempo fa...
+
+
+Interfaccia stabile nei sorgenti del kernel
+-------------------------------------------
+
+Se parlate con le persone che cercano di mantenere aggiornato un driver per
+Linux ma che non si trova nei sorgenti, allora per queste persone l'argomento
+sarà "ostico".
+
+Lo sviluppo del kernel Linux è continuo e viaggia ad un ritmo sostenuto, e non
+rallenta mai. Perciò, gli sviluppatori del kernel trovano bachi nelle
+interfacce attuali, o trovano modi migliori per fare le cose. Se le trovano,
+allora le correggeranno per migliorarle. In questo frangente, i nomi delle
+funzioni potrebbero cambiare, le strutture dati potrebbero diventare più grandi
+o più piccole, e gli argomenti delle funzioni potrebbero essere ripensati.
+Se questo dovesse succedere, nello stesso momento, tutte le istanze dove questa
+interfaccia viene utilizzata verranno corrette, garantendo che tutto continui
+a funzionare senza problemi.
+
+Portiamo ad esempio l'interfaccia interna per il sottosistema USB che ha subito
+tre ristrutturazioni nel corso della sua vita. Queste ristrutturazioni furono
+fatte per risolvere diversi problemi:
+
+ - È stato fatto un cambiamento da un flusso di dati sincrono ad uno
+ asincrono. Questo ha ridotto la complessità di molti driver e ha
+ aumentato la capacità di trasmissione di tutti i driver fino a raggiungere
+ quasi la velocità massima possibile.
+ - È stato fatto un cambiamento nell'allocazione dei pacchetti da parte del
+ sottosistema USB per conto dei driver, cosicché ora i driver devono fornire
+ più informazioni al sottosistema USB al fine di correggere un certo numero
+ di stalli.
+
+Questo è completamente l'opposto di quello che succede in alcuni sistemi
+operativi proprietari che hanno dovuto mantenere, nel tempo, il supporto alle
+vecchie interfacce USB. I nuovi sviluppatori potrebbero usare accidentalmente
+le vecchie interfacce e sviluppare codice nel modo sbagliato, portando, di
+conseguenza, all'instabilità del sistema.
+
+In entrambe gli scenari, gli sviluppatori hanno ritenuto che queste importanti
+modifiche erano necessarie, e quindi le hanno fatte con qualche sofferenza.
+Se Linux avesse assicurato di mantenere stabile l'interfaccia interna, si
+sarebbe dovuto procedere alla creazione di una nuova, e quelle vecchie, e
+mal funzionanti, avrebbero dovuto ricevere manutenzione, creando lavoro
+aggiuntivo per gli sviluppatori del sottosistema USB. Dato che gli
+sviluppatori devono dedicare il proprio tempo a questo genere di lavoro,
+chiedergli di dedicarne dell'altro, senza benefici, magari gratuitamente, non
+è contemplabile.
+
+Le problematiche relative alla sicurezza sono molto importanti per Linux.
+Quando viene trovato un problema di sicurezza viene corretto in breve tempo.
+A volte, per prevenire il problema di sicurezza, si sono dovute cambiare
+delle interfacce interne al kernel. Quando è successo, allo stesso tempo,
+tutti i driver che usavano quelle interfacce sono stati aggiornati, garantendo
+la correzione definitiva del problema senza doversi preoccupare di rivederlo
+per sbaglio in futuro. Se non si fossero cambiate le interfacce interne,
+sarebbe stato impossibile correggere il problema e garantire che non si sarebbe
+più ripetuto.
+
+Nel tempo le interfacce del kernel subiscono qualche ripulita. Se nessuno
+sta più usando un'interfaccia, allora questa verrà rimossa. Questo permette
+al kernel di rimanere il più piccolo possibile, e garantisce che tutte le
+potenziali interfacce sono state verificate nel limite del possibile (le
+interfacce inutilizzate sono impossibili da verificare).
+
+
+Cosa fare
+---------
+
+Dunque, se avete un driver per il kernel Linux che non si trova nei sorgenti
+principali del kernel, come sviluppatori, cosa dovreste fare? Rilasciare un
+file binario del driver per ogni versione del kernel e per ogni distribuzione,
+è un incubo; inoltre, tenere il passo con tutti i cambiamenti del kernel è un
+brutto lavoro.
+
+Semplicemente, fate sì che il vostro driver per il kernel venga incluso nei
+sorgenti principali (ricordatevi, stiamo parlando di driver rilasciati secondo
+una licenza compatibile con la GPL; se il vostro codice non ricade in questa
+categoria: buona fortuna, arrangiatevi, siete delle sanguisughe)
+
+Se il vostro driver è nei sorgenti del kernel e un'interfaccia cambia, il
+driver verrà corretto immediatamente dalla persona che l'ha modificata. Questo
+garantisce che sia sempre possibile compilare il driver, che funzioni, e tutto
+con un minimo sforzo da parte vostra.
+
+Avere il proprio driver nei sorgenti principali del kernel ha i seguenti
+vantaggi:
+
+ - La qualità del driver aumenterà e i costi di manutenzione (per lo
+ sviluppatore originale) diminuiranno.
+ - Altri sviluppatori aggiungeranno nuove funzionalità al vostro driver.
+ - Altri persone troveranno e correggeranno bachi nel vostro driver.
+ - Altri persone troveranno degli aggiustamenti da fare al vostro driver.
+ - Altri persone aggiorneranno il driver quando è richiesto da un cambiamento
+ di un'interfaccia.
+ - Il driver sarà automaticamente reso disponibile in tutte le distribuzioni
+ Linux senza dover chiedere a nessuna di queste di aggiungerlo.
+
+Dato che Linux supporta più dispositivi di qualsiasi altro sistema operativo,
+e che girano su molti più tipi di processori di qualsiasi altro sistema
+operativo; ciò dimostra che questo modello di sviluppo qualcosa di giusto,
+dopo tutto, lo fa :)

+
+Lista delle verifiche da fare prima di inviare una patch per il kernel Linux
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Qui troverete una lista di cose che uno sviluppatore dovrebbe fare per
+vedere le proprie patch accettate più rapidamente.
+
+Tutti questi punti integrano la documentazione fornita riguardo alla
+sottomissione delle patch, in particolare
+:ref:`Documentation/translations/it_IT/process/submitting-patches.rst <it_submittingpatches>`.
+
+1) Se state usando delle funzionalità del kernel allora includete (#include)
+ i file che le dichiarano/definiscono. Non dipendente dal fatto che un file
+ d'intestazione include anche quelli usati da voi.
+
+2) Compilazione pulita:
+
+ a) con le opzioni ``CONFIG`` negli stati ``=y``, ``=m`` e ``=n``. Nessun
+ avviso/errore di ``gcc`` e nessun avviso/errore dal linker.
+
+ b) con ``allnoconfig``, ``allmodconfig``
+
+ c) quando si usa ``O=builddir``
+
+3) Compilare per diverse architetture di processore usando strumenti per
+ la cross-compilazione o altri.
+
+4) Una buona architettura per la verifica della cross-compilazione è la ppc64
+ perché tende ad usare ``unsigned long`` per le quantità a 64-bit.
+
+5) Controllate lo stile del codice della vostra patch secondo le direttive
+ scritte in :ref:`Documentation/translations/it_IT/process/coding-style.rst <it_codingstyle>`.
+ Prima dell'invio della patch, usate il verificatore di stile
+ (``script/checkpatch.pl``) per scovare le violazioni più semplici.
+ Dovreste essere in grado di giustificare tutte le violazioni rimanenti nella
+ vostra patch.
+
+6) Le opzioni ``CONFIG``, nuove o modificate, non scombussolano il menu
+ di configurazione e sono preimpostate come disabilitate a meno che non
+ soddisfino i criteri descritti in ``Documentation/kbuild/kconfig-language.txt``
+ alla punto "Voci di menu: valori predefiniti".
+
+7) Tutte le nuove opzioni ``Kconfig`` hanno un messaggio di aiuto.
+
+8) La patch è stata accuratamente revisionata rispetto alle più importanti
+ configurazioni ``Kconfig``. Questo è molto difficile da fare
+ correttamente - un buono lavoro di testa sarà utile.
+
+9) Verificare con sparse.
+
+10) Usare ``make checkstack`` e ``make namespacecheck`` e correggere tutti i
+ problemi rilevati.
+
+ .. note::
+
+ ``checkstack`` non evidenzia esplicitamente i problemi, ma una funzione
+ che usa più di 512 byte sullo stack è una buona candidata per una
+ correzione.
+
+11) Includete commenti :ref:`kernel-doc <kernel_doc>` per documentare API
+ globali del kernel. Usate ``make htmldocs`` o ``make pdfdocs`` per
+ verificare i commenti :ref:`kernel-doc <kernel_doc>` ed eventualmente
+ correggerli.
+
+12) La patch è stata verificata con le seguenti opzioni abilitate
+ contemporaneamente: ``CONFIG_PREEMPT``, ``CONFIG_DEBUG_PREEMPT``,
+ ``CONFIG_DEBUG_SLAB``, ``CONFIG_DEBUG_PAGEALLOC``, ``CONFIG_DEBUG_MUTEXES``,
+ ``CONFIG_DEBUG_SPINLOCK``, ``CONFIG_DEBUG_ATOMIC_SLEEP``,
+ ``CONFIG_PROVE_RCU`` e ``CONFIG_DEBUG_OBJECTS_RCU_HEAD``.
+
+13) La patch è stata compilata e verificata in esecuzione con, e senza,
+ le opzioni ``CONFIG_SMP`` e ``CONFIG_PREEMPT``.
+
+14) Se la patch ha effetti sull'IO dei dischi, eccetera: allora dev'essere
+ verificata con, e senza, l'opzione ``CONFIG_LBDAF``.
+
+15) Tutti i percorsi del codice sono stati verificati con tutte le funzionalità
+ di lockdep abilitate.
+
+16) Tutti i nuovi elementi in ``/proc`` sono documentati in ``Documentation/``.
+
+17) Tutti i nuovi parametri d'avvio del kernel sono documentati in
+ ``Documentation/admin-guide/kernel-parameters.rst``.
+
+18) Tutti i nuovi parametri dei moduli sono documentati con ``MODULE_PARM_DESC()``.
+
+19) Tutte le nuove interfacce verso lo spazio utente sono documentate in
+ ``Documentation/ABI/``. Leggete ``Documentation/ABI/README`` per maggiori
+ informazioni. Le patch che modificano le interfacce utente dovrebbero
+ essere inviate in copia anche a linux-api@vger.kernel.org.
+
+20) Verifica che il kernel passi con successo ``make headers_check``
+
+21) La patch è stata verificata con l'iniezione di fallimenti in slab e
+ nell'allocazione di pagine. Vedere ``Documentation/fault-injection/``.
+
+ Se il nuovo codice è corposo, potrebbe essere opportuno aggiungere
+ l'iniezione di fallimenti specifici per il sottosistema.
+
+22) Il nuovo codice è stato compilato con ``gcc -W`` (usate
+ ``make EXTRA_CFLAGS=-W``). Questo genererà molti avvisi, ma è ottimo
+ per scovare bachi come "warning: comparison between signed and unsigned".
+
+23) La patch è stata verificata dopo essere stata inclusa nella serie di patch
+ -mm; questo al fine di assicurarsi che continui a funzionare assieme a
+ tutte le altre patch in coda e i vari cambiamenti nei sottosistemi VM, VFS
+ e altri.
+
+24) Tutte le barriere di sincronizzazione {per esempio, ``barrier()``,
+ ``rmb()``, ``wmb()``} devono essere accompagnate da un commento nei
+ sorgenti che ne spieghi la logica: cosa fanno e perché.
+
+25) Se la patch aggiunge nuove chiamate ioctl, allora aggiornate
+ ``Documentation/ioctl/ioctl-number.txt``.
+
+26) Se il codice che avete modificato dipende o usa una qualsiasi interfaccia o
+ funzionalità del kernel che è associata a uno dei seguenti simboli
+ ``Kconfig``, allora verificate che il kernel compili con diverse
+ configurazioni dove i simboli sono disabilitati e/o ``=m`` (se c'è la
+ possibilità) [non tutti contemporaneamente, solo diverse combinazioni
+ casuali]:
+
+ ``CONFIG_SMP``, ``CONFIG_SYSFS``, ``CONFIG_PROC_FS``, ``CONFIG_INPUT``,
+ ``CONFIG_PCI``, ``CONFIG_BLOCK``, ``CONFIG_PM``, ``CONFIG_MAGIC_SYSRQ``,
+ ``CONFIG_NET``, ``CONFIG_INET=n`` (ma l'ultimo con ``CONFIG_NET=y``).

+Inviare patch: la guida essenziale per vedere il vostro codice nel kernel
+=========================================================================
+
+Una persona o un'azienda che volesse inviare una patch al kernel potrebbe
+sentirsi scoraggiata dal processo di sottomissione, specialmente quando manca
+una certa familiarità col "sistema". Questo testo è una raccolta di
+suggerimenti che aumenteranno significativamente le probabilità di vedere le
+vostre patch accettate.
+
+Questo documento contiene un vasto numero di suggerimenti concisi. Per
+maggiori dettagli su come funziona il processo di sviluppo del kernel leggete
+:ref:`Documentation/translations/it_IT/process <it_development_process_main>`.
+Leggete anche :ref:`Documentation/translations/it_IT/process/submit-checklist.rst <it_submitchecklist>`
+per una lista di punti da verificare prima di inviare del codice. Se state
+inviando un driver, allora leggete anche :ref:`Documentation/translations/it_IT/process/submitting-drivers.rst <it_submittingdrivers>`;
+per delle patch relative alle associazioni per Device Tree leggete
+Documentation/devicetree/bindings/submitting-patches.txt.
+
+Molti di questi passi descrivono il comportamento di base del sistema di
+controllo di versione ``git``; se utilizzate ``git`` per preparare le vostre
+patch molto del lavoro più ripetitivo lo troverete già fatto per voi, tuttavia
+dovete preparare e documentare un certo numero di patch. Generalmente, l'uso
+di ``git`` renderà la vostra vita di sviluppatore del kernel più facile.
+
+0) Ottenere i sorgenti attuali
+------------------------------
+
+Se non avete un repositorio coi sorgenti del kernel più recenti, allora usate
+``git`` per ottenerli. Vorrete iniziare col repositorio principale che può
+essere recuperato col comando::
+
+ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
+
+Notate, comunque, che potreste non voler sviluppare direttamente coi sorgenti
+principali del kernel. La maggior parte dei manutentori hanno i propri
+sorgenti e desiderano che le patch siano preparate basandosi su di essi.
+Guardate l'elemento **T:** per un determinato sottosistema nel file MAINTANERS
+che troverete nei sorgenti, o semplicemente chiedete al manutentore nel caso
+in cui i sorgenti da usare non siano elencati il quel file.
+
+Esiste ancora la possibilità di scaricare un rilascio del kernel come archivio
+tar (come descritto in una delle prossime sezioni), ma questa è la via più
+complicata per sviluppare per il kernel.
+
+1) ``diff -up``
+---------------
+
+Se dovete produrre le vostre patch a mano, usate ``diff -up`` o ``diff -uprN``
+per crearle. Git produce di base le patch in questo formato; se state
+usando ``git``, potete saltare interamente questa sezione.
+
+Tutte le modifiche al kernel Linux avvengono mediate patch, come descritte
+in :manpage:`diff(1)`. Quando create la vostra patch, assicuratevi di
+crearla nel formato "unified diff", come l'argomento ``-u`` di
+:manpage:`diff(1)`.
+Inoltre, per favore usate l'argomento ``-p`` per mostrare la funzione C
+alla quale si riferiscono le diverse modifiche - questo rende il risultato
+di ``diff`` molto più facile da leggere. Le patch dovrebbero essere basate
+sulla radice dei sorgenti del kernel, e non sulle sue sottocartelle.
+
+Per creare una patch per un singolo file, spesso è sufficiente fare::
+
+ SRCTREE= linux
+ MYFILE= drivers/net/mydriver.c
+
+ cd $SRCTREE
+ cp $MYFILE $MYFILE.orig
+ vi $MYFILE # make your change
+ cd ..
+ diff -up $SRCTREE/$MYFILE{.orig,} > /tmp/patch
+
+Per creare una patch per molteplici file, dovreste spacchettare i sorgenti
+"vergini", o comunque non modificati, e fare un ``diff`` coi vostri.
+Per esempio::
+
+ MYSRC= /devel/linux
+
+ tar xvfz linux-3.19.tar.gz
+ mv linux-3.19 linux-3.19-vanilla
+ diff -uprN -X linux-3.19-vanilla/Documentation/dontdiff \
+ linux-3.19-vanilla $MYSRC > /tmp/patch
+
+``dontdiff`` è una lista di file che sono generati durante il processo di
+compilazione del kernel; questi dovrebbero essere ignorati in qualsiasi
+patch generata con :manpage:`diff(1)`.
+
+Assicuratevi che la vostra patch non includa file che non ne fanno veramente
+parte. Al fine di verificarne la correttezza, assicuratevi anche di
+revisionare la vostra patch -dopo- averla generata con :manpage:`diff(1)`.
+
+Se le vostre modifiche producono molte differenze, allora dovrete dividerle
+in patch indipendenti che modificano le cose in passi logici; leggete
+:ref:`split_changes`. Questo faciliterà la revisione da parte degli altri
+sviluppatori, il che è molto importante se volete che la patch venga accettata.
+
+Se state utilizzando ``git``, ``git rebase -i`` può aiutarvi nel procedimento.
+Se non usate ``git``, un'alternativa popolare è ``quilt``
+<http://savannah.nongnu.org/projects/quilt>.
+
+.. _it_describe_changes:
+
+2) Descrivete le vostre modifiche
+---------------------------------
+
+Descrivete il vostro problema. Esiste sempre un problema che via ha spinto
+ha fare il vostro lavoro, che sia la correzione di un baco da una riga o una
+nuova funzionalità da 5000 righe di codice. Convincete i revisori che vale
+la pena risolvere il vostro problema e che ha senso continuare a leggere oltre
+al primo paragrafo.
+
+Descrivete ciò che sarà visibile agli utenti. Chiari incidenti nel sistema
+e blocchi sono abbastanza convincenti, ma non tutti i bachi sono così evidenti.
+Anche se il problema è stato scoperto durante la revisione del codice,
+descrivete l'impatto che questo avrà sugli utenti. Tenete presente che
+la maggior parte delle installazioni Linux usa un kernel che arriva dai
+sorgenti stabili o dai sorgenti di una distribuzione particolare che prende
+singolarmente le patch dai sorgenti principali; quindi, includete tutte
+le informazioni che possono essere utili a capire le vostre modifiche:
+le circostanze che causano il problema, estratti da dmesg, descrizioni di
+un incidente di sistema, prestazioni di una regressione, picchi di latenza,
+blocchi, eccetera.
+
+Quantificare le ottimizzazioni e i compromessi. Se affermate di aver
+migliorato le prestazioni, il consumo di memoria, l'impatto sollo stack,
+o la dimensione del file binario, includete dei numeri a supporto della
+vostra dichiarazione. Ma ricordatevi di descrivere anche eventuali costi
+che non sono ovvi. Solitamente le ottimizzazioni non sono gratuite, ma sono
+un compromesso fra l'uso di CPU, la memoria e la leggibilità; o, quando si
+parla di ipotesi euristiche, fra differenti carichi. Descrivete i lati
+negativi che vi aspettate dall'ottimizzazione cosicché i revisori possano
+valutare i costi e i benefici.
+
+Una volta che il problema è chiaro, descrivete come lo risolvete andando
+nel dettaglio tecnico. È molto importante che descriviate la modifica
+in un inglese semplice cosicché i revisori possano verificare che il codice si
+comporti come descritto.
+
+I manutentori vi saranno grati se scrivete la descrizione della patch in un
+formato che sia compatibile con il gestore dei sorgenti usato dal kernel,
+``git``, come un "commit log". Leggete :ref:`it_explicit_in_reply_to`.
+
+Risolvete solo un problema per patch. Se la vostra descrizione inizia ad
+essere lunga, potrebbe essere un segno che la vostra patch necessita d'essere
+divisa. Leggete :ref:`split_changes`.
+
+Quando inviate o rinviate una patch o una serie, includete la descrizione
+completa delle modifiche e la loro giustificazione. Non limitatevi a dire che
+questa è la versione N della patch (o serie). Non aspettatevi che i
+manutentori di un sottosistema vadano a cercare le versioni precedenti per
+cercare la descrizione da aggiungere. In pratica, la patch (o serie) e la sua
+descrizione devono essere un'unica cosa. Questo aiuta i manutentori e i
+revisori. Probabilmente, alcuni revisori non hanno nemmeno ricevuto o visto
+le versioni precedenti della patch.
+
+Descrivete le vostro modifiche usando l'imperativo, per esempio "make xyzzy
+do frotz" piuttosto che "[This patch] makes xyzzy do frotz" or "[I] changed
+xyzzy to do frotz", come se steste dando ordini al codice di cambiare il suo
+comportamento.
+
+Se la patch corregge un baco conosciuto, fare riferimento a quel baco inserendo
+il suo numero o il suo URL. Se la patch è la conseguenza di una discussione
+su una lista di discussione, allora fornite l'URL all'archivio di quella
+discussione; usate i collegamenti a https://lkml.kernel.org/ con il
+``Message-Id``, in questo modo vi assicurerete che il collegamento non diventi
+invalido nel tempo.
+
+Tuttavia, cercate di rendere la vostra spiegazione comprensibile anche senza
+far riferimento a fonti esterne. In aggiunta ai collegamenti a bachi e liste
+di discussione, riassumente i punti più importanti della discussione che hanno
+portato alla creazione della patch.
+
+Se volete far riferimento a uno specifico commit, non usate solo
+l'identificativo SHA-1. Per cortesia, aggiungete anche la breve riga
+riassuntiva del commit per rendere la chiaro ai revisori l'oggetto.
+Per esempio::
+
+ Commit e21d2170f36602ae2708 ("video: remove unnecessary
+ platform_set_drvdata()") removed the unnecessary
+ platform_set_drvdata(), but left the variable "dev" unused,
+ delete it.
+
+Dovreste anche assicurarvi di usare almeno i primi 12 caratteri
+dell'identificativo SHA-1. Il repositorio del kernel ha *molti* oggetti e
+questo rende possibile la collisione fra due identificativi con pochi
+caratteri. Tenete ben presente che anche se oggi non ci sono collisioni con il
+vostro identificativo a 6 caratteri, potrebbero essercene fra 5 anni da oggi.
+
+Se la vostra patch corregge un baco in un commit specifico, per esempio avete
+trovato un problema usando ``git bisect``, per favore usate l'etichetta
+'Fixes:' indicando i primi 12 caratteri dell'identificativo SHA-1 seguiti
+dalla riga riassuntiva. Per esempio::
+
+ Fixes: e21d2170f366 ("video: remove unnecessary platform_set_drvdata()")
+
+La seguente configurazione di ``git config`` può essere usata per formattare
+i risultati dei comandi ``git log`` o ``git show`` come nell'esempio
+precedente::
+
+ [core]
+ abbrev = 12
+ [pretty]
+ fixes = Fixes: %h (\"%s\")
+
+.. _it_split_changes:
+
+3) Separate le vostre modifiche
+-------------------------------
+
+Separate ogni **cambiamento logico** in patch distinte.
+
+Per esempio, se i vostri cambiamenti per un singolo driver includono
+sia delle correzioni di bachi che miglioramenti alle prestazioni,
+allora separateli in due o più patch. Se i vostri cambiamenti includono
+un aggiornamento dell'API e un nuovo driver che lo sfrutta, allora separateli
+in due patch.
+
+D'altro canto, se fate una singola modifica su più file, raggruppate tutte
+queste modifiche in una singola patch. Dunque, un singolo cambiamento logico
+è contenuto in una sola patch.
+
+Il punto da ricordare è che ogni modifica dovrebbe fare delle modifiche
+che siano facilmente comprensibili e che possano essere verificate dai revisori.
+Ogni patch dovrebbe essere giustificabile di per sé.
+
+Se al fine di ottenere un cambiamento completo una patch dipende da un'altra,
+va bene. Semplicemente scrivete una nota nella descrizione della patch per
+farlo presente: **"this patch depends on patch X"**.
+
+Quando dividete i vostri cambiamenti in una serie di patch, prestate
+particolare attenzione alla verifica di ogni patch della serie; per ognuna
+il kernel deve compilare ed essere eseguito correttamente. Gli sviluppatori
+che usano ``git bisect`` per scovare i problemi potrebbero finire nel mezzo
+della vostra serie in un punto qualsiasi; non vi saranno grati se nel mezzo
+avete introdotto dei bachi.
+
+Se non potete condensare la vostra serie di patch in una più piccola, allora
+pubblicatene una quindicina alla volta e aspettate che vengano revisionate
+ed integrate.
+
+
+4) Verificate lo stile delle vostre modifiche
+---------------------------------------------
+
+Controllate che la vostra patch non violi lo stile del codice, maggiori
+dettagli sono disponibili in :ref:`Documentation/translations/it_IT/process/coding-style.rst <it_codingstyle>`.
+Non farlo porta semplicemente a una perdita di tempo da parte dei revisori e
+voi vedrete la vostra patch rifiutata, probabilmente senza nemmeno essere stata
+letta.
+
+Un'eccezione importante si ha quando del codice viene spostato da un file
+ad un altro -- in questo caso non dovreste modificare il codice spostato
+per nessun motivo, almeno non nella patch che lo sposta. Questo separa
+chiaramente l'azione di spostare il codice e il vostro cambiamento.
+Questo aiuta enormemente la revisione delle vere differenze e permette agli
+strumenti di tenere meglio la traccia della storia del codice.
+
+Prima di inviare una patch, verificatene lo stile usando l'apposito
+verificatore (scripts/checkpatch.pl). Da notare, comunque, che il verificator
+di stile dovrebbe essere visto come una guida, non come un sostituto al
+giudizio umano. Se il vostro codice è migliore nonostante una violazione
+dello stile, probabilmente è meglio lasciarlo com'è.
+
+Il verificatore ha tre diversi livelli di severità:
+ - ERROR: le cose sono molto probabilmente sbagliate
+ - WARNING: le cose necessitano d'essere revisionate con attenzione
+ - CHECK: le cose necessitano di un pensierino
+
+Dovreste essere in grado di giustificare tutte le eventuali violazioni rimaste
+nella vostra patch.
+
+
+5) Selezionate i destinatari della vostra patch
+-----------------------------------------------
+
+Dovreste sempre inviare una copia della patch ai manutentori dei sottosistemi
+interessati dalle modifiche; date un'occhiata al file MAINTAINERS e alla storia
+delle revisioni per scoprire chi si occupa del codice. Lo script
+scripts/get_maintainer.pl può esservi d'aiuto. Se non riuscite a trovare un
+manutentore per il sottosistema su cui state lavorando, allora Andrew Morton
+(akpm@linux-foundation.org) sarà la vostra ultima possibilità.
+
+Normalmente, dovreste anche scegliere una lista di discussione a cui inviare
+la vostra serie di patch. La lista di discussione linux-kernel@vger.kernel.org
+è proprio l'ultima spiaggia, il volume di email su questa lista fa si che
+diversi sviluppatori non la seguano. Guardate nel file MAINTAINERS per trovare
+la lista di discussione dedicata ad un sottosistema; probabilmente lì la vostra
+patch riceverà molta più attenzione. Tuttavia, per favore, non spammate le
+liste di discussione che non sono interessate al vostro lavoro.
+
+Molte delle liste di discussione relative al kernel vengono ospitate su
+vger.kernel.org; potete trovare un loro elenco alla pagina
+http://vger.kernel.org/vger-lists.html. Tuttavia, ci sono altre liste di
+discussione ospitate altrove.
+
+Non inviate più di 15 patch alla volta sulle liste di discussione vger!!!
+
+L'ultimo giudizio sull'integrazione delle modifiche accettate spetta a
+Linux Torvalds. Il suo indirizzo e-mail è <torvalds@linux-foundation.org>.
+Riceve moltissime e-mail, e, a questo punto, solo poche patch passano
+direttamente attraverso il suo giudizio; quindi, dovreste fare del vostro
+meglio per -evitare di- inviargli e-mail.
+
+Se avete una patch che corregge un baco di sicurezza che potrebbe essere
+sfruttato, inviatela a security@kernel.org. Per bachi importanti, un breve
+embargo potrebbe essere preso in considerazione per dare il tempo alle
+distribuzioni di prendere la patch e renderla disponibile ai loro utenti;
+in questo caso, ovviamente, la patch non dovrebbe essere inviata su alcuna
+lista di discussione pubblica.
+
+Patch che correggono bachi importanti su un kernel già rilasciato, dovrebbero
+essere inviate ai manutentori dei kernel stabili aggiungendo la seguente riga::
+
+ Cc: stable@vger.kernel.org
+
+nella vostra patch, nell'area dedicata alle firme (notate, NON come destinatario
+delle e-mail). In aggiunta a questo file, dovreste leggere anche
+:ref:`Documentation/translations/it_IT/process/stable-kernel-rules.rst <it_stable_kernel_rules>`
+
+Tuttavia, notate, che alcuni manutentori di sottosistema preferiscono avere
+l'ultima parola su quali patch dovrebbero essere aggiunte ai kernel stabili.
+La rete di manutentori, in particolare, non vorrebbe vedere i singoli
+sviluppatori aggiungere alle loro patch delle righe come quella sopracitata.
+
+Se le modifiche hanno effetti sull'interfaccia con lo spazio utente, per favore
+inviate una patch per le pagine man ai manutentori di suddette pagine (elencati
+nel file MAINTAINERS), o almeno una notifica circa la vostra modifica,
+cosicché l'informazione possa trovare la sua strada nel manuale. Le modifiche
+all'API dello spazio utente dovrebbero essere inviate in copia anche a
+linux-api@vger.kernel.org.
+
+Per le piccole patch potreste aggiungere in CC l'indirizzo
+*Trivial Patch Monkey trivial@kernel.org* che ha lo scopo di raccogliere
+le patch "banali". Date uno sguardo al file MAINTAINERS per vedere chi
+è l'attuale amministratore.
+
+Le patch banali devono rientrare in una delle seguenti categorie:
+
+- errori grammaticali nella documentazione
+- errori grammaticali negli errori che potrebbero rompere :manpage:`grep(1)`
+- correzione di avvisi di compilazione (riempirsi di avvisi inutili è negativo)
+- correzione di errori di compilazione (solo se correggono qualcosa sul serio)
+- rimozione di funzioni/macro deprecate
+- sostituzione di codice non potabile con uno portabile (anche in codice
+ specifico per un'architettura, dato che le persone copiano, fintanto che
+ la modifica sia banale)
+- qualsiasi modifica dell'autore/manutentore di un file (in pratica
+ "patch monkey" in modalità ritrasmissione)
+
+
+6) Niente: MIME, links, compressione, allegati. Solo puro testo
+----------------------------------------------------------------
+
+Linus e gli altri sviluppatori del kernel devono poter commentare
+le modifiche che sottomettete. Per uno sviluppatore è importante
+essere in grado di "citare" le vostre modifiche, usando normali
+programmi di posta elettronica, cosicché sia possibile commentare
+una porzione specifica del vostro codice.
+
+Per questa ragione tutte le patch devono essere inviate via e-mail
+come testo.
+
+.. warning::
+
+ Se decidete di copiare ed incollare la patch nel corpo dell'e-mail, state
+ attenti che il vostro programma non corrompa il contenuto con andate
+ a capo automatiche.
+
+La patch non deve essere un allegato MIME, compresso o meno. Molti
+dei più popolari programmi di posta elettronica non trasmettono un allegato
+MIME come puro testo, e questo rende impossibile commentare il vostro codice.
+Inoltre, un allegato MIME rende l'attività di Linus più laboriosa, diminuendo
+così la possibilità che il vostro allegato-MIME venga accettato.
+
+Eccezione: se il vostro servizio di posta storpia le patch, allora qualcuno
+potrebbe chiedervi di rinviarle come allegato MIME.
+
+Leggete :ref:`Documentation/translations/it_IT/process/email-clients.rst <it_email_clients>`
+per dei suggerimenti sulla configurazione del programmi di posta elettronica
+per l'invio di patch intatte.
+
+7) Dimensione delle e-mail
+--------------------------
+
+Le grosse modifiche non sono adatte ad una lista di discussione, e nemmeno
+per alcuni manutentori. Se la vostra patch, non compressa, eccede i 300 kB
+di spazio, allora caricatela in una spazio accessibile su internet fornendo
+l'URL (collegamento) ad essa. Ma notate che se la vostra patch eccede i 300 kB
+è quasi certo che necessiti comunque di essere spezzettata.
+
+8) Rispondere ai commenti di revisione
+--------------------------------------
+
+Quasi certamente i revisori vi invieranno dei commenti su come migliorare
+la vostra patch. Dovete rispondere a questi commenti; ignorare i revisori
+è un ottimo modo per essere ignorati. Riscontri o domande che non conducono
+ad una modifica del codice quasi certamente dovrebbero portare ad un commento
+nel changelog cosicché il prossimo revisore potrà meglio comprendere cosa stia
+accadendo.
+
+Assicuratevi di dire ai revisori quali cambiamenti state facendo e di
+ringraziarli per il loro tempo. Revisionare codice è un lavoro faticoso e che
+richiede molto tempo, e a volte i revisori diventano burberi. Tuttavia, anche
+in questo caso, rispondete con educazione e concentratevi sul problema che
+hanno evidenziato.
+
+9) Non scoraggiatevi - o impazientitevi
+---------------------------------------
+
+Dopo che avete inviato le vostre modifiche, siate pazienti e aspettate.
+I revisori sono persone occupate e potrebbero non ricevere la vostra patch
+immediatamente.
+
+Un tempo, le patch erano solite scomparire nel vuoto senza alcun commento,
+ma ora il processo di sviluppo funziona meglio. Dovreste ricevere commenti
+in una settimana o poco più; se questo non dovesse accadere, assicuratevi di
+aver inviato le patch correttamente. Aspettate almeno una settimana prima di
+rinviare le modifiche o sollecitare i revisori - probabilmente anche di più
+durante la finestra d'integrazione.
+
+10) Aggiungete PATCH nell'oggetto
+---------------------------------
+
+Dato l'alto volume di e-mail per Linus, e la lista linux-kernel, è prassi
+prefiggere il vostro oggetto con [PATCH]. Questo permette a Linus e agli
+altri sviluppatori del kernel di distinguere facilmente le patch dalle altre
+discussioni.
+
+
+11) Firmate il vostro lavoro - Il certificato d'origine dello sviluppatore
+--------------------------------------------------------------------------
+
+Per migliorare la tracciabilità su "chi ha fatto cosa", specialmente per
+quelle patch che per raggiungere lo stadio finale passano attraverso
+diversi livelli di manutentori, abbiamo introdotto la procedura di "firma"
+delle patch che vengono inviate per e-mail.
+
+La firma è una semplice riga alla fine della descrizione della patch che
+certifica che l'avete scritta voi o che avete il diritto di pubblicarla
+come patch open-source. Le regole sono abbastanza semplici: se potete
+certificare quanto segue:
+
+Il certificato d'origine dello sviluppatore 1.1
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Contribuendo a questo progetto, io certifico che:
+
+ (a) Il contributo è stato creato interamente, o in parte, da me e che
+ ho il diritto di inviarlo in accordo con la licenza open-source
+ indicata nel file; oppure
+
+ (b) Il contributo è basato su un lavoro precedente che, nei limiti
+ della mia conoscenza, è coperto da un'appropriata licenza
+ open-source che mi da il diritto di modificarlo e inviarlo,
+ le cui modifiche sono interamente o in parte mie, in accordo con
+ la licenza open-source (a meno che non abbia il permesso di usare
+ un'altra licenza) indicata nel file; oppure
+
+ (c) Il contributo mi è stato fornito direttamente da qualcuno che
+ ha certificato (a), (b) o (c) e non l'ho modificata.
+
+ (d) Capisco e concordo col fatto che questo progetto e i suoi
+ contributi sono pubblici e che un registro dei contributi (incluse
+ tutte le informazioni personali che invio con essi, inclusa la mia
+ firma) verrà mantenuto indefinitamente e che possa essere
+ ridistribuito in accordo con questo progetto o le licenze
+ open-source coinvolte.
+
+poi dovete solo aggiungere una riga che dice::
+
+ Signed-off-by: Random J Developer <random@developer.example.org>
+
+usando il vostro vero nome (spiacenti, non si accettano pseudonimi o
+contributi anonimi).
+
+Alcune persone aggiungono delle etichette alla fine. Per ora queste verranno
+ignorate, ma potete farlo per meglio identificare procedure aziendali interne o
+per aggiungere dettagli circa la firma.
+
+Se siete un manutentore di un sottosistema o di un ramo, qualche volta dovrete
+modificare leggermente le patch che avete ricevuto al fine di poterle
+integrare; questo perché il codice non è esattamente lo stesso nei vostri
+sorgenti e in quelli dei vostri contributori. Se rispettate rigidamente la
+regola (c), dovreste chiedere al mittente di rifare la patch, ma questo è
+controproducente e una totale perdita di tempo ed energia. La regola (b)
+vi permette di correggere il codice, ma poi diventa davvero maleducato cambiare
+la patch di qualcuno e addossargli la responsabilità per i vostri bachi.
+Per risolvere questo problema dovreste aggiungere una riga, fra l'ultimo
+Signed-off-by e il vostro, che spiega la vostra modifica. Nonostante non ci
+sia nulla di obbligatorio, un modo efficace è quello di indicare il vostro
+nome o indirizzo email fra parentesi quadre, seguito da una breve descrizione;
+questo renderà abbastanza visibile chi è responsabile per le modifiche
+dell'ultimo minuto. Per esempio::
+
+ Signed-off-by: Random J Developer <random@developer.example.org>
+ [lucky@maintainer.example.org: struct foo moved from foo.c to foo.h]
+ Signed-off-by: Lucky K Maintainer <lucky@maintainer.example.org>
+
+Questa pratica è particolarmente utile se siete i manutentori di un ramo
+stabile ma al contempo volete dare credito agli autori, tracciare e integrare
+le modifiche, e proteggere i mittenti dalle lamentele. Notate che in nessuna
+circostanza è permessa la modifica dell'identità dell'autore (l'intestazione
+From), dato che è quella che appare nei changelog.
+
+Un appunto speciale per chi porta il codice su vecchie versioni. Sembra che
+sia comune l'utile pratica di inserire un'indicazione circa l'origine della
+patch all'inizio del messaggio di commit (appena dopo la riga dell'oggetto)
+al fine di migliorare la tracciabilità. Per esempio, questo è quello che si
+vede nel rilascio stabile 3.x-stable::
+
+ Date: Tue Oct 7 07:26:38 2014 -0400
+
+ libata: Un-break ATA blacklist
+
+ commit 1c40279960bcd7d52dbdf1d466b20d24b99176c8 upstream.
+
+E qui quello che potrebbe vedersi su un kernel più vecchio dove la patch è
+stata applicata::
+
+ Date: Tue May 13 22:12:27 2008 +0200
+
+ wireless, airo: waitbusy() won't delay
+
+ [backport of 2.6 commit b7acbdfbd1f277c1eb23f344f899cfa4cd0bf36a]
+
+Qualunque sia il formato, questa informazione fornisce un importante aiuto
+alle persone che vogliono seguire i vostri sorgenti, e quelle che cercano
+dei bachi.
+
+
+12) Quando utilizzare Acked-by:, Cc:, e Co-developed-by:
+--------------------------------------------------------
+
+L'etichetta Signed-off-by: indica che il firmatario è stato coinvolto nello
+sviluppo della patch, o che era nel suo percorso di consegna.
+
+Se una persona non è direttamente coinvolta con la preparazione o gestione
+della patch ma desidera firmare e mettere agli atti la loro approvazione,
+allora queste persone possono chiedere di aggiungere al changelog della patch
+una riga Acked-by:.
+
+Acked-by: viene spesso utilizzato dai manutentori del sottosistema in oggetto
+quando quello stesso manutentore non ha contribuito né trasmesso la patch.
+
+Acked-by: non è formale come Signed-off-by:. Questo indica che la persona ha
+revisionato la patch e l'ha trovata accettabile. Per cui, a volte, chi
+integra le patch convertirà un "sì, mi sembra che vada bene" in un Acked-by:
+(ma tenete presente che solitamente è meglio chiedere esplicitamente).
+
+Acked-by: non indica l'accettazione di un'intera patch. Per esempio, quando
+una patch ha effetti su diversi sottosistemi e ha un Acked-by: da un
+manutentore di uno di questi, significa che il manutentore accetta quella
+parte di codice relativa al sottosistema che mantiene. Qui dovremmo essere
+giudiziosi. Quando si hanno dei dubbi si dovrebbe far riferimento alla
+discussione originale negli archivi della lista di discussione.
+
+Se una persona ha avuto l'opportunità di commentare la patch, ma non lo ha
+fatto, potete aggiungere l'etichetta ``Cc:`` alla patch. Questa è l'unica
+etichetta che può essere aggiunta senza che la persona in questione faccia
+alcunché - ma dovrebbe indicare che la persona ha ricevuto una copia della
+patch. Questa etichetta documenta che terzi potenzialmente interessati sono
+stati inclusi nella discussione.
+
+L'etichetta Co-developed-by: indica che la patch è stata scritta dall'autore in
+collaborazione con un altro sviluppatore. Qualche volta questo è utile quando
+più persone lavorano sulla stessa patch. Notate, questa persona deve avere
+nella patch anche una riga Signed-off-by:.
+
+
+13) Utilizzare Reported-by:, Tested-by:, Reviewed-by:, Suggested-by: e Fixes:
+-----------------------------------------------------------------------------
+
+L'etichetta Reported-by da credito alle persone che trovano e riportano i bachi
+e si spera che questo possa ispirarli ad aiutarci nuovamente in futuro.
+Rammentate che se il baco è stato riportato in privato, dovrete chiedere il
+permesso prima di poter utilizzare l'etichetta Reported-by.
+
+L'etichetta Tested-by: indica che la patch è stata verificata con successo
+(su un qualche sistema) dalla persona citata. Questa etichetta informa i
+manutentori che qualche verifica è stata fatta, fornisce un mezzo per trovare
+persone che possano verificare il codice in futuro, e garantisce che queste
+stesse persone ricevano credito per il loro lavoro.
+
+Reviewd-by:, invece, indica che la patch è stata revisionata ed è stata
+considerata accettabile in accordo con la dichiarazione dei revisori:
+
+Dichiarazione di svista dei revisori
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Offrendo la mia etichetta Reviewed-by, dichiaro quanto segue:
+
+ (a) Ho effettuato una revisione tecnica di questa patch per valutarne
+ l'adeguatezza ai fini dell'inclusione nel ramo principale del
+ kernel.
+
+ (b) Tutti i problemi e le domande riguardanti la patch sono stati
+ comunicati al mittente. Sono soddisfatto dalle risposte
+ del mittente.
+
+ (c) Nonostante ci potrebbero essere cose migliorabili in queste
+ sottomissione, credo che sia, in questo momento, (1) una modifica
+ di interesse per il kernel, e (2) libera da problemi che
+ potrebbero metterne in discussione l'integrazione.
+
+ (d) Nonostante abbia revisionato la patch e creda che vada bene,
+ non garantisco (se non specificato altrimenti) che questa
+ otterrà quello che promette o funzionerà correttamente in tutte
+ le possibili situazioni.
+
+L'etichetta Reviewed-by è la dichiarazione di un parere sulla bontà di
+una modifica che si ritiene appropriata e senza alcun problema tecnico
+importante. Qualsiasi revisore interessato (quelli che lo hanno fatto)
+possono offrire il proprio Reviewed-by per la patch. Questa etichetta serve
+a dare credito ai revisori e a informare i manutentori sul livello di revisione
+che è stato fatto sulla patch. L'etichetta Reviewd-by, quando fornita da
+revisori conosciuti per la loro conoscenza sulla materia in oggetto e per la
+loro serietà nella revisione, accrescerà le probabilità che la vostra patch
+venga integrate nel kernel.
+
+L'etichetta Suggested-by: indica che l'idea della patch è stata suggerita
+dalla persona nominata e le da credito. Tenete a mente che questa etichetta
+non dovrebbe essere aggiunta senza un permesso esplicito, specialmente se
+l'idea non è stata pubblicata in un forum pubblico. Detto ciò, dando credito
+a chi ci fornisce delle idee, si spera di poterli ispirare ad aiutarci
+nuovamente in futuro.
+
+L'etichetta Fixes: indica che la patch corregge un problema in un commit
+precedente. Serve a chiarire l'origine di un baco, il che aiuta la revisione
+del baco stesso. Questa etichetta è di aiuto anche per i manutentori dei
+kernel stabili al fine di capire quale kernel deve ricevere la correzione.
+Questo è il modo suggerito per indicare che un baco è stato corretto nella
+patch. Per maggiori dettagli leggete :ref:`it_describe_changes`
+
+
+14) Il formato canonico delle patch
+-----------------------------------
+
+Questa sezione descrive il formato che dovrebbe essere usato per le patch.
+Notate che se state usando un repositorio ``git`` per salvare le vostre patch
+potere usare il comando ``git format-patch`` per ottenere patch nel formato
+appropriato. Lo strumento non crea il testo necessario, per cui, leggete
+le seguenti istruzioni.
+
+L'oggetto di una patch canonica è la riga::
+
+ Subject: [PATCH 001/123] subsystem: summary phrase
+
+Il corpo di una patch canonica contiene i seguenti elementi:
+
+ - Una riga ``from`` che specifica l'autore della patch, seguita
+ da una riga vuota (necessaria soltanto se la persona che invia la
+ patch non ne è l'autore).
+
+ - Il corpo della spiegazione, con linee non più lunghe di 75 caratteri,
+ che verrà copiato permanentemente nel changelog per descrivere la patch.
+
+ - Una riga vuota
+
+ - Le righe ``Signed-off-by:``, descritte in precedenza, che finiranno
+ anch'esse nel changelog.
+
+ - Una linea di demarcazione contenente semplicemente ``---``.
+
+ - Qualsiasi altro commento che non deve finire nel changelog.
+
+ - Le effettive modifiche al codice (il prodotto di ``diff``).
+
+Il formato usato per l'oggetto permette ai programmi di posta di usarlo
+per ordinare le patch alfabeticamente - tutti i programmi di posta hanno
+questa funzionalità - dato che al numero sequenziale si antepongono degli zeri;
+in questo modo l'ordine numerico ed alfabetico coincidono.
+
+Il ``subsystem`` nell'oggetto dell'email dovrebbe identificare l'area
+o il sottosistema modificato dalla patch.
+
+La ``summary phrase`` nell'oggetto dell'email dovrebbe descrivere brevemente
+il contenuto della patch. La ``summary phrase`` non dovrebbe essere un nome
+di file. Non utilizzate la stessa ``summary phrase`` per tutte le patch in
+una serie (dove una ``serie di patch`` è una sequenza ordinata di diverse
+patch correlate).
+
+Ricordatevi che la ``summary phrase`` della vostra email diventerà un
+identificatore globale ed unico per quella patch. Si propaga fino al
+changelog ``git``. La ``summary phrase`` potrà essere usata in futuro
+dagli sviluppatori per riferirsi a quella patch. Le persone vorranno
+cercare la ``summary phrase`` su internet per leggere le discussioni che la
+riguardano. Potrebbe anche essere l'unica cosa che le persone vedranno
+quando, in due o tre mesi, riguarderanno centinaia di patch usando strumenti
+come ``gitk`` o ``git log --oneline``.
+
+Per queste ragioni, dovrebbe essere lunga fra i 70 e i 75 caratteri, e deve
+descrivere sia cosa viene modificato, sia il perché sia necessario. Essere
+brevi e descrittivi è una bella sfida, ma questo è quello che fa un riassunto
+ben scritto.
+
+La ``summary phrase`` può avere un'etichetta (*tag*) di prefisso racchiusa fra
+le parentesi quadre "Subject: [PATCH <tag>...] <summary phrase>".
+Le etichette non verranno considerate come parte della frase riassuntiva, ma
+indicano come la patch dovrebbe essere trattata. Fra le etichette più comuni
+ci sono quelle di versione che vengono usate quando una patch è stata inviata
+più volte (per esempio, "v1, v2, v3"); oppure "RFC" per indicare che si
+attendono dei commenti (*Request For Comments*). Se ci sono quattro patch
+nella serie, queste dovrebbero essere enumerate così: 1/4, 2/4, 3/4, 4/4.
+Questo assicura che gli sviluppatori capiranno l'ordine in cui le patch
+dovrebbero essere applicate, e per tracciare quelle che hanno revisionate o
+che hanno applicato.
+
+Un paio di esempi di oggetti::
+
+ Subject: [PATCH 2/5] ext2: improve scalability of bitmap searching
+ Subject: [PATCH v2 01/27] x86: fix eflags tracking
+
+La riga ``from`` dev'essere la prima nel corpo del messaggio ed è nel
+formato:
+
+ From: Original Author <author@example.com>
+
+La riga ``from`` indica chi verrà accreditato nel changelog permanente come
+l'autore della patch. Se la riga ``from`` è mancante, allora per determinare
+l'autore da inserire nel changelog verrà usata la riga ``From``
+nell'intestazione dell'email.
+
+Il corpo della spiegazione verrà incluso nel changelog permanente, per cui
+deve aver senso per un lettore esperto che è ha dimenticato i dettagli della
+discussione che hanno portato alla patch. L'inclusione di informazioni
+sui problemi oggetto dalla patch (messaggi del kernel, messaggi di oops,
+eccetera) è particolarmente utile per le persone che potrebbero cercare fra
+i messaggi di log per la patch che li tratta. Se la patch corregge un errore
+di compilazione, non sarà necessario includere proprio _tutto_ quello che
+è uscito dal compilatore; aggiungete solo quello che è necessario per far si
+che la vostra patch venga trovata. Come nella ``summary phrase``, è importante
+essere sia brevi che descrittivi.
+
+La linea di demarcazione ``---`` serve essenzialmente a segnare dove finisce
+il messaggio di changelog.
+
+Aggiungere il ``diffstat`` dopo ``---`` è un buon uso di questo spazio, per
+mostrare i file che sono cambiati, e il numero di file aggiunto o rimossi.
+Un ``diffstat`` è particolarmente utile per le patch grandi. Altri commenti
+che sono importanti solo per i manutentori, quindi inadatti al changelog
+permanente, dovrebbero essere messi qui. Un buon esempio per questo tipo
+di commenti potrebbe essere quello di descrivere le differenze fra le versioni
+della patch.
+
+Se includete un ``diffstat`` dopo ``---``, usate le opzioni ``-p 1 -w70``
+cosicché i nomi dei file elencati non occupino troppo spazio (facilmente
+rientreranno negli 80 caratteri, magari con qualche indentazione).
+(``git`` genera di base dei diffstat adatti).
+
+Maggiori dettagli sul formato delle patch nei riferimenti qui di seguito.
+
+.. _it_explicit_in_reply_to:
+
+15) Usare esplicitamente In-Reply-To nell'intestazione
+------------------------------------------------------
+
+Aggiungere manualmente In-Reply-To: nell'intestazione dell'e-mail
+potrebbe essere d'aiuto per associare una patch ad una discussione
+precedente, per esempio per collegare la correzione di un baco con l'e-mail
+che lo riportava. Tuttavia, per serie di patch multiple è generalmente
+sconsigliato l'uso di In-Reply-To: per collegare precedenti versioni.
+In questo modo versioni multiple di una patch non diventeranno un'ingestibile
+giungla di riferimenti all'interno dei programmi di posta. Se un collegamento
+è utile, potete usare https://lkml.kernel.org/ per ottenere i collegamenti
+ad una versione precedente di una serie di patch (per esempio, potete usarlo
+per l'email introduttiva alla serie).
+
+16) Inviare richieste ``git pull``
+----------------------------------
+
+Se avete una serie di patch, potrebbe essere più conveniente per un manutentore
+tirarle dentro al repositorio del sottosistema attraverso l'operazione
+``git pull``. Comunque, tenete presente che prendere patch da uno sviluppatore
+in questo modo richiede un livello di fiducia più alto rispetto a prenderle da
+una lista di discussione. Di conseguenza, molti manutentori sono riluttanti
+ad accettare richieste di *pull*, specialmente dagli sviluppatori nuovi e
+quindi sconosciuti. Se siete in dubbio, potete fare una richiesta di *pull*
+come messaggio introduttivo ad una normale pubblicazione di patch, così
+il manutentore avrà la possibilità di scegliere come integrarle.
+
+Una richiesta di *pull* dovrebbe avere nell'oggetto [GIT] o [PULL].
+La richiesta stessa dovrebbe includere il nome del repositorio e quello del
+ramo su una singola riga; dovrebbe essere più o meno così::
+
+ Please pull from
+
+ git://jdelvare.pck.nerim.net/jdelvare-2.6 i2c-for-linus
+
+ to get these changes:
+
+Una richiesta di *pull* dovrebbe includere anche un messaggio generico
+che dica cos'è incluso, una lista delle patch usando ``git shortlog``, e una
+panoramica sugli effetti della serie di patch con ``diffstat``. Il modo più
+semplice per ottenere tutte queste informazioni è, ovviamente, quello di
+lasciar fare tutto a ``git`` con il comando ``git request-pull``.
+
+Alcuni manutentori (incluso Linus) vogliono vedere le richieste di *pull*
+da commit firmati con GPG; questo fornisce una maggiore garanzia sul fatto
+che siate stati proprio voi a fare la richiesta. In assenza di tale etichetta
+firmata Linus, in particolare, non prenderà alcuna patch da siti pubblici come
+GitHub.
+
+Il primo passo verso la creazione di questa etichetta firmata è quello di
+creare una chiave GNUPG ed averla fatta firmare da uno o più sviluppatori
+principali del kernel. Questo potrebbe essere difficile per i nuovi
+sviluppatori, ma non ci sono altre vie. Andare alle conferenze potrebbe
+essere un buon modo per trovare sviluppatori che possano firmare la vostra
+chiave.
+
+Una volta che avete preparato la vostra serie di patch in ``git``, e volete che
+qualcuno le prenda, create una etichetta firmata col comando ``git tag -s``.
+Questo creerà una nuova etichetta che identifica l'ultimo commit della serie

+
+Perché la parola chiave "volatile" non dovrebbe essere usata
+------------------------------------------------------------
+
+Spesso i programmatori C considerano volatili quelle variabili che potrebbero
+essere cambiate al di fuori dal thread di esecuzione corrente; come risultato,
+a volte saranno tentati dall'utilizzare *volatile* nel kernel per le
+strutture dati condivise. In altre parole, gli è stato insegnato ad usare
+*volatile* come una variabile atomica di facile utilizzo, ma non è così.
+L'uso di *volatile* nel kernel non è quasi mai corretto; questo documento ne
+descrive le ragioni.
+
+Il punto chiave da capire su *volatile* è che il suo scopo è quello di
+sopprimere le ottimizzazioni, che non è quasi mai quello che si vuole.
+Nel kernel si devono proteggere le strutture dati condivise contro accessi
+concorrenti e indesiderati: questa è un'attività completamente diversa.
+Il processo di protezione contro gli accessi concorrenti indesiderati eviterà
+anche la maggior parte dei problemi relativi all'ottimizzazione in modo più
+efficiente.
+
+Come *volatile*, le primitive del kernel che rendono sicuro l'accesso ai dati
+(spinlock, mutex, barriere di sincronizzazione, ecc) sono progettate per
+prevenire le ottimizzazioni indesiderate. Se vengono usate opportunamente,
+non ci sarà bisogno di utilizzare *volatile*. Se vi sembra che *volatile* sia
+comunque necessario, ci dev'essere quasi sicuramente un baco da qualche parte.
+In un pezzo di codice kernel scritto a dovere, *volatile* può solo servire a
+rallentare le cose.
+
+Considerate questo tipico blocco di codice kernel::
+
+ spin_lock(&the_lock);
+ do_something_on(&shared_data);
+ do_something_else_with(&shared_data);
+ spin_unlock(&the_lock);
+
+Se tutto il codice seguisse le regole di sincronizzazione, il valore di un
+dato condiviso non potrebbe cambiare inaspettatamente mentre si trattiene un
+lock. Un qualsiasi altro blocco di codice che vorrà usare quel dato rimarrà
+in attesa del lock. Gli spinlock agiscono come barriere di sincronizzazione
+- sono stati esplicitamente scritti per agire così - il che significa che gli
+accessi al dato condiviso non saranno ottimizzati. Quindi il compilatore
+potrebbe pensare di sapere cosa ci sarà nel dato condiviso ma la chiamata
+spin_lock(), che agisce come una barriera di sincronizzazione, gli imporrà di
+dimenticarsi tutto ciò che sapeva su di esso.
+
+Se il dato condiviso fosse stato dichiarato come *volatile*, la
+sincronizzazione rimarrebbe comunque necessaria. Ma verrà impedito al
+compilatore di ottimizzare gli accessi al dato anche _dentro_ alla sezione
+critica, dove sappiamo che in realtà nessun altro può accedervi. Mentre si
+trattiene un lock, il dato condiviso non è *volatile*. Quando si ha a che
+fare con dei dati condivisi, un'opportuna sincronizzazione rende inutile
+l'uso di *volatile* - anzi potenzialmente dannoso.
+
+L'uso di *volatile* fu originalmente pensato per l'accesso ai registri di I/O
+mappati in memoria. All'interno del kernel, l'accesso ai registri, dovrebbe
+essere protetto dai lock, ma si potrebbe anche desiderare che il compilatore
+non "ottimizzi" l'accesso ai registri all'interno di una sezione critica.
+Ma, all'interno del kernel, l'accesso alla memoria di I/O viene sempre fatto
+attraverso funzioni d'accesso; accedere alla memoria di I/O direttamente
+con i puntatori è sconsigliato e non funziona su tutte le architetture.
+Queste funzioni d'accesso sono scritte per evitare ottimizzazioni indesiderate,
+quindi, di nuovo, *volatile* è inutile.
+
+Un'altra situazione dove qualcuno potrebbe essere tentato dall'uso di
+*volatile*, è nel caso in cui il processore è in un'attesa attiva sul valore
+di una variabile. Il modo giusto di fare questo tipo di attesa è il seguente::
+
+ while (my_variable != what_i_want)
+ cpu_relax();
+
+La chiamata cpu_relax() può ridurre il consumo di energia del processore
+o cedere il passo ad un processore hyperthreaded gemello; funziona anche come
+una barriera per il compilatore, quindi, ancora una volta, *volatile* non è
+necessario. Ovviamente, tanto per puntualizzare, le attese attive sono
+generalmente un atto antisociale.
+
+Ci sono comunque alcune rare situazioni dove l'uso di *volatile* nel kernel
+ha senso:
+
+ - Le funzioni d'accesso sopracitate potrebbero usare *volatile* su quelle
+ architetture che supportano l'accesso diretto alla memoria di I/O.
+ In pratica, ogni chiamata ad una funzione d'accesso diventa una piccola
+ sezione critica a se stante, e garantisce che l'accesso avvenga secondo
+ le aspettative del programmatore.
+
+ - I codice *inline assembly* che fa cambiamenti nella memoria, ma che non
+ ha altri effetti espliciti, rischia di essere rimosso da GCC. Aggiungere
+ la parola chiave *volatile* a questo codice ne previene la rimozione.
+
+ - La variabile jiffies è speciale in quanto assume un valore diverso ogni
+ volta che viene letta ma può essere lette senza alcuna sincronizzazione.
+ Quindi jiffies può essere *volatile*, ma l'aggiunta ad altre variabili di
+ questo è sconsigliata. Jiffies è considerata uno "stupido retaggio"
+ (parole di Linus) in questo contesto; correggerla non ne varrebbe la pena e
+ causerebbe più problemi.
+
+ - I puntatori a delle strutture dati in una memoria coerente che potrebbe
+ essere modificata da dispositivi di I/O può, a volte, essere legittimamente
+ *volatile*. Un esempio pratico può essere quello di un adattatore di rete
+ che utilizza un puntatore ad un buffer circolare, questo viene cambiato
+ dall'adattatore per indicare quali descrittori sono stati processati.
+
+Per la maggior parte del codice, nessuna delle giustificazioni sopracitate può
+essere considerata. Di conseguenza, l'uso di *volatile* è probabile che venga
+visto come un baco e porterà a verifiche aggiuntive. Gli sviluppatori tentati
+dall'uso di *volatile* dovrebbero fermarsi e pensare a cosa vogliono davvero
+ottenere.
+
+Le modifiche che rimuovono variabili *volatile* sono generalmente ben accette
+- purché accompagnate da una giustificazione che dimostri che i problemi di
+concorrenza siano stati opportunamente considerati.

+Userspace Notification
+======================
+
+The ``SECCOMP_RET_USER_NOTIF`` return code lets seccomp filters pass a
+particular syscall to userspace to be handled. This may be useful for
+applications like container managers, which wish to intercept particular
+syscalls (``mount()``, ``finit_module()``, etc.) and change their behavior.
+
+To acquire a notification FD, use the ``SECCOMP_FILTER_FLAG_NEW_LISTENER``
+argument to the ``seccomp()`` syscall:
+
+.. code-block:: c
+
+ fd = seccomp(SECCOMP_SET_MODE_FILTER, SECCOMP_FILTER_FLAG_NEW_LISTENER, &prog);
+
+which (on success) will return a listener fd for the filter, which can then be
+passed around via ``SCM_RIGHTS`` or similar. Note that filter fds correspond to
+a particular filter, and not a particular task. So if this task then forks,
+notifications from both tasks will appear on the same filter fd. Reads and
+writes to/from a filter fd are also synchronized, so a filter fd can safely
+have many readers.
+
+The interface for a seccomp notification fd consists of two structures:
+
+.. code-block:: c
+
+ struct seccomp_notif_sizes {
+ __u16 seccomp_notif;
+ __u16 seccomp_notif_resp;
+ __u16 seccomp_data;
+ };
+
+ struct seccomp_notif {
+ __u64 id;
+ __u32 pid;
+ __u32 flags;
+ struct seccomp_data data;
+ };
+
+ struct seccomp_notif_resp {
+ __u64 id;
+ __s64 val;
+ __s32 error;
+ __u32 flags;
+ };
+
+The ``struct seccomp_notif_sizes`` structure can be used to determine the size
+of the various structures used in seccomp notifications. The size of ``struct
+seccomp_data`` may change in the future, so code should use:
+
+.. code-block:: c
+
+ struct seccomp_notif_sizes sizes;
+ seccomp(SECCOMP_GET_NOTIF_SIZES, 0, &sizes);
+
+to determine the size of the various structures to allocate. See
+samples/seccomp/user-trap.c for an example.
+
+Users can read via ``ioctl(SECCOMP_IOCTL_NOTIF_RECV)`` (or ``poll()``) on a
+seccomp notification fd to receive a ``struct seccomp_notif``, which contains
+five members: the input length of the structure, a unique-per-filter ``id``,
+the ``pid`` of the task which triggered this request (which may be 0 if the
+task is in a pid ns not visible from the listener's pid namespace), a ``flags``
+member which for now only has ``SECCOMP_NOTIF_FLAG_SIGNALED``, representing
+whether or not the notification is a result of a non-fatal signal, and the
+``data`` passed to seccomp. Userspace can then make a decision based on this
+information about what to do, and ``ioctl(SECCOMP_IOCTL_NOTIF_SEND)`` a
+response, indicating what should be returned to userspace. The ``id`` member of
+``struct seccomp_notif_resp`` should be the same ``id`` as in ``struct
+seccomp_notif``.
+
+It is worth noting that ``struct seccomp_data`` contains the values of register
+arguments to the syscall, but does not contain pointers to memory. The task's
+memory is accessible to suitably privileged traces via ``ptrace()`` or
+``/proc/pid/mem``. However, care should be taken to avoid the TOCTOU mentioned
+above in this document: all arguments being read from the tracee's memory
+should be read into the tracer's memory before any policy decisions are made.
+This allows for an atomic decision on syscall arguments.

+With this capability enabled, KVM_GET_DIRTY_LOG will not automatically
+clear and write-protect all pages that are returned as dirty.
+Rather, userspace will have to do this operation separately using
+KVM_CLEAR_DIRTY_LOG.
+
+At the cost of a slightly more complicated operation, this provides better
+scalability and responsiveness for two reasons. First,
+KVM_CLEAR_DIRTY_LOG ioctl can operate on a 64-page granularity rather
+than requiring to sync a full memslot; this ensures that KVM does not
+take spinlocks for an extended period of time. Second, in some cases a
+large amount of time can pass between a call to KVM_GET_DIRTY_LOG and
+userspace actually using the data in the page. Pages can be modified
+during this time, which is inefficint for both the guest and userspace:
+the guest will incur a higher penalty due to write protection faults,
+while userspace can see false reports of dirty pages. Manual reprotection
+helps reducing this time, improving guest performance and reducing the
+number of dirty log false positives.

+ Mellanox watchdog drivers
+ for x86 based system switches
+
+This driver provides watchdog functionality for various Mellanox
+Ethernet and Infiniband switch systems.
+
+Mellanox watchdog device is implemented in a programmable logic device.
+
+There are 2 types of HW watchdog implementations.
+
+Type 1:
+Actual HW timeout can be defined as a power of 2 msec.
+e.g. timeout 20 sec will be rounded up to 32768 msec.
+The maximum timeout period is 32 sec (32768 msec.),
+Get time-left isn't supported
+
+Type 2:
+Actual HW timeout is defined in sec. and it's the same as
+a user-defined timeout.
+Maximum timeout is 255 sec.
+Get time-left is supported.
+
+Type 1 HW watchdog implementation exist in old systems and
+all new systems have type 2 HW watchdog.
+Two types of HW implementation have also different register map.
+
+Mellanox system can have 2 watchdogs: main and auxiliary.
+Main and auxiliary watchdog devices can be enabled together
+on the same system.
+There are several actions that can be defined in the watchdog:
+system reset, start fans on full speed and increase register counter.
+The last 2 actions are performed without a system reset.
+Actions without reset are provided for auxiliary watchdog device,
+which is optional.
+Watchdog can be started during a probe, in this case it will be
+pinged by watchdog core before watchdog device will be opened by
+user space application.
+Watchdog can be initialised in nowayout way, i.e. oncse started
+it can't be stopped.
+
+This mlx-wdt driver supports both HW watchdog implementations.
+
+Watchdog driver is probed from the common mlx_platform driver.
+Mlx_platform driver provides an appropriate set of registers for
+Mellanox watchdog device, identity name (mlx-wdt-main or mlx-wdt-aux),
+initial timeout, performed action in expiration and configuration flags.
+watchdog configuration flags: nowayout and start_at_boot, hw watchdog
+version - type1 or type2.
+The driver checks during initialization if the previous system reset
+was done by the watchdog. If yes, it makes a notification about this event.
+
+Access to HW registers is performed through a generic regmap interface.

-User Interface for Resource Allocation in Intel Resource Director Technology
-
-Copyright (C) 2016 Intel Corporation
-
-Fenghua Yu <fenghua.yu@intel.com>
-Tony Luck <tony.luck@intel.com>
-Vikas Shivappa <vikas.shivappa@intel.com>
-
-This feature is enabled by the CONFIG_INTEL_RDT Kconfig and the
-X86 /proc/cpuinfo flag bits:
-RDT (Resource Director Technology) Allocation - "rdt_a"
-CAT (Cache Allocation Technology) - "cat_l3", "cat_l2"
-CDP (Code and Data Prioritization ) - "cdp_l3", "cdp_l2"
-CQM (Cache QoS Monitoring) - "cqm_llc", "cqm_occup_llc"
-MBM (Memory Bandwidth Monitoring) - "cqm_mbm_total", "cqm_mbm_local"
-MBA (Memory Bandwidth Allocation) - "mba"
-
-To use the feature mount the file system:
-
- # mount -t resctrl resctrl [-o cdp[,cdpl2][,mba_MBps]] /sys/fs/resctrl
-
-mount options are:
-
-"cdp": Enable code/data prioritization in L3 cache allocations.
-"cdpl2": Enable code/data prioritization in L2 cache allocations.
-"mba_MBps": Enable the MBA Software Controller(mba_sc) to specify MBA
- bandwidth in MBps
-
-L2 and L3 CDP are controlled seperately.
-
-RDT features are orthogonal. A particular system may support only
-monitoring, only control, or both monitoring and control. Cache
-pseudo-locking is a unique way of using cache control to "pin" or
-"lock" data in the cache. Details can be found in
-"Cache Pseudo-Locking".
-
-
-The mount succeeds if either of allocation or monitoring is present, but
-only those files and directories supported by the system will be created.
-For more details on the behavior of the interface during monitoring
-and allocation, see the "Resource alloc and monitor groups" section.
-
-Info directory
---------------
-
-The 'info' directory contains information about the enabled
-resources. Each resource has its own subdirectory. The subdirectory
-names reflect the resource names.
-
-Each subdirectory contains the following files with respect to
-allocation:
-
-Cache resource(L3/L2) subdirectory contains the following files
-related to allocation:
-
-"num_closids": The number of CLOSIDs which are valid for this
- resource. The kernel uses the smallest number of
- CLOSIDs of all enabled resources as limit.
-
-"cbm_mask": The bitmask which is valid for this resource.
- This mask is equivalent to 100%.
-
-"min_cbm_bits": The minimum number of consecutive bits which
- must be set when writing a mask.
-
-"shareable_bits": Bitmask of shareable resource with other executing
- entities (e.g. I/O). User can use this when
- setting up exclusive cache partitions. Note that
- some platforms support devices that have their
- own settings for cache use which can over-ride
- these bits.
-"bit_usage": Annotated capacity bitmasks showing how all
- instances of the resource are used. The legend is:
- "0" - Corresponding region is unused. When the system's
- resources have been allocated and a "0" is found
- in "bit_usage" it is a sign that resources are
- wasted.
- "H" - Corresponding region is used by hardware only
- but available for software use. If a resource
- has bits set in "shareable_bits" but not all
- of these bits appear in the resource groups'
- schematas then the bits appearing in
- "shareable_bits" but no resource group will
- be marked as "H".
- "X" - Corresponding region is available for sharing and
- used by hardware and software. These are the
- bits that appear in "shareable_bits" as
- well as a resource group's allocation.
- "S" - Corresponding region is used by software
- and available for sharing.
- "E" - Corresponding region is used exclusively by
- one resource group. No sharing allowed.
- "P" - Corresponding region is pseudo-locked. No
- sharing allowed.
-
-Memory bandwitdh(MB) subdirectory contains the following files
-with respect to allocation:
-
-"min_bandwidth": The minimum memory bandwidth percentage which
- user can request.
-
-"bandwidth_gran": The granularity in which the memory bandwidth
- percentage is allocated. The allocated
- b/w percentage is rounded off to the next
- control step available on the hardware. The
- available bandwidth control steps are:
- min_bandwidth + N * bandwidth_gran.
-
-"delay_linear": Indicates if the delay scale is linear or
- non-linear. This field is purely informational
- only.
-
-If RDT monitoring is available there will be an "L3_MON" directory
-with the following files:
-
-"num_rmids": The number of RMIDs available. This is the
- upper bound for how many "CTRL_MON" + "MON"
- groups can be created.
-
-"mon_features": Lists the monitoring events if
- monitoring is enabled for the resource.
-
-"max_threshold_occupancy":
- Read/write file provides the largest value (in
- bytes) at which a previously used LLC_occupancy
- counter can be considered for re-use.
-
-Finally, in the top level of the "info" directory there is a file
-named "last_cmd_status". This is reset with every "command" issued
-via the file system (making new directories or writing to any of the
-control files). If the command was successful, it will read as "ok".
-If the command failed, it will provide more information that can be
-conveyed in the error returns from file operations. E.g.
-
- # echo L3:0=f7 > schemata
- bash: echo: write error: Invalid argument
- # cat info/last_cmd_status
- mask f7 has non-consecutive 1-bits
-
-Resource alloc and monitor groups
----------------------------------
-
-Resource groups are represented as directories in the resctrl file
-system. The default group is the root directory which, immediately
-after mounting, owns all the tasks and cpus in the system and can make
-full use of all resources.
-
-On a system with RDT control features additional directories can be
-created in the root directory that specify different amounts of each
-resource (see "schemata" below). The root and these additional top level
-directories are referred to as "CTRL_MON" groups below.
-
-On a system with RDT monitoring the root directory and other top level
-directories contain a directory named "mon_groups" in which additional
-directories can be created to monitor subsets of tasks in the CTRL_MON
-group that is their ancestor. These are called "MON" groups in the rest
-of this document.
-
-Removing a directory will move all tasks and cpus owned by the group it
-represents to the parent. Removing one of the created CTRL_MON groups
-will automatically remove all MON groups below it.
-
-All groups contain the following files:
-
-"tasks":
- Reading this file shows the list of all tasks that belong to
- this group. Writing a task id to the file will add a task to the
- group. If the group is a CTRL_MON group the task is removed from
- whichever previous CTRL_MON group owned the task and also from
- any MON group that owned the task. If the group is a MON group,
- then the task must already belong to the CTRL_MON parent of this
- group. The task is removed from any previous MON group.
-
-
-"cpus":
- Reading this file shows a bitmask of the logical CPUs owned by
- this group. Writing a mask to this file will add and remove
- CPUs to/from this group. As with the tasks file a hierarchy is
- maintained where MON groups may only include CPUs owned by the
- parent CTRL_MON group.
- When the resouce group is in pseudo-locked mode this file will
- only be readable, reflecting the CPUs associated with the
- pseudo-locked region.
-
-
-"cpus_list":
- Just like "cpus", only using ranges of CPUs instead of bitmasks.
-
-
-When control is enabled all CTRL_MON groups will also contain:
-
-"schemata":
- A list of all the resources available to this group.
- Each resource has its own line and format - see below for details.
-
-"size":
- Mirrors the display of the "schemata" file to display the size in
- bytes of each allocation instead of the bits representing the
- allocation.
-
-"mode":
- The "mode" of the resource group dictates the sharing of its
- allocations. A "shareable" resource group allows sharing of its
- allocations while an "exclusive" resource group does not. A
- cache pseudo-locked region is created by first writing
- "pseudo-locksetup" to the "mode" file before writing the cache
- pseudo-locked region's schemata to the resource group's "schemata"
- file. On successful pseudo-locked region creation the mode will
- automatically change to "pseudo-locked".
-
-When monitoring is enabled all MON groups will also contain:
-
-"mon_data":
- This contains a set of files organized by L3 domain and by
- RDT event. E.g. on a system with two L3 domains there will
- be subdirectories "mon_L3_00" and "mon_L3_01". Each of these
- directories have one file per event (e.g. "llc_occupancy",
- "mbm_total_bytes", and "mbm_local_bytes"). In a MON group these
- files provide a read out of the current value of the event for
- all tasks in the group. In CTRL_MON groups these files provide
- the sum for all tasks in the CTRL_MON group and all tasks in
- MON groups. Please see example section for more details on usage.
-
-Resource allocation rules
--------------------------
-When a task is running the following rules define which resources are
-available to it:
-
-1) If the task is a member of a non-default group, then the schemata
- for that group is used.
-
-2) Else if the task belongs to the default group, but is running on a
- CPU that is assigned to some specific group, then the schemata for the
- CPU's group is used.
-
-3) Otherwise the schemata for the default group is used.
-
-Resource monitoring rules
--------------------------
-1) If a task is a member of a MON group, or non-default CTRL_MON group
- then RDT events for the task will be reported in that group.
-
-2) If a task is a member of the default CTRL_MON group, but is running
- on a CPU that is assigned to some specific group, then the RDT events
- for the task will be reported in that group.
-
-3) Otherwise RDT events for the task will be reported in the root level
- "mon_data" group.
-
-
-Notes on cache occupancy monitoring and control
------------------------------------------------
-When moving a task from one group to another you should remember that
-this only affects *new* cache allocations by the task. E.g. you may have
-a task in a monitor group showing 3 MB of cache occupancy. If you move
-to a new group and immediately check the occupancy of the old and new
-groups you will likely see that the old group is still showing 3 MB and
-the new group zero. When the task accesses locations still in cache from
-before the move, the h/w does not update any counters. On a busy system
-you will likely see the occupancy in the old group go down as cache lines
-are evicted and re-used while the occupancy in the new group rises as
-the task accesses memory and loads into the cache are counted based on
-membership in the new group.
-
-The same applies to cache allocation control. Moving a task to a group
-with a smaller cache partition will not evict any cache lines. The
-process may continue to use them from the old partition.
-
-Hardware uses CLOSid(Class of service ID) and an RMID(Resource monitoring ID)
-to identify a control group and a monitoring group respectively. Each of
-the resource groups are mapped to these IDs based on the kind of group. The
-number of CLOSid and RMID are limited by the hardware and hence the creation of
-a "CTRL_MON" directory may fail if we run out of either CLOSID or RMID
-and creation of "MON" group may fail if we run out of RMIDs.
-
-max_threshold_occupancy - generic concepts
-------------------------------------------
-
-Note that an RMID once freed may not be immediately available for use as
-the RMID is still tagged the cache lines of the previous user of RMID.
-Hence such RMIDs are placed on limbo list and checked back if the cache
-occupancy has gone down. If there is a time when system has a lot of
-limbo RMIDs but which are not ready to be used, user may see an -EBUSY
-during mkdir.
-
-max_threshold_occupancy is a user configurable value to determine the
-occupancy at which an RMID can be freed.
-
-Schemata files - general concepts
----------------------------------
-Each line in the file describes one resource. The line starts with
-the name of the resource, followed by specific values to be applied
-in each of the instances of that resource on the system.
-
-Cache IDs
----------
-On current generation systems there is one L3 cache per socket and L2
-caches are generally just shared by the hyperthreads on a core, but this
-isn't an architectural requirement. We could have multiple separate L3
-caches on a socket, multiple cores could share an L2 cache. So instead
-of using "socket" or "core" to define the set of logical cpus sharing
-a resource we use a "Cache ID". At a given cache level this will be a
-unique number across the whole system (but it isn't guaranteed to be a
-contiguous sequence, there may be gaps). To find the ID for each logical
-CPU look in /sys/devices/system/cpu/cpu*/cache/index*/id
-
-Cache Bit Masks (CBM)
----------------------
-For cache resources we describe the portion of the cache that is available
-for allocation using a bitmask. The maximum value of the mask is defined
-by each cpu model (and may be different for different cache levels). It
-is found using CPUID, but is also provided in the "info" directory of
-the resctrl file system in "info/{resource}/cbm_mask". X86 hardware
-requires that these masks have all the '1' bits in a contiguous block. So
-0x3, 0x6 and 0xC are legal 4-bit masks with two bits set, but 0x5, 0x9
-and 0xA are not. On a system with a 20-bit mask each bit represents 5%
-of the capacity of the cache. You could partition the cache into four
-equal parts with masks: 0x1f, 0x3e0, 0x7c00, 0xf8000.
-
-Memory bandwidth Allocation and monitoring
-------------------------------------------
-
-For Memory bandwidth resource, by default the user controls the resource
-by indicating the percentage of total memory bandwidth.
-
-The minimum bandwidth percentage value for each cpu model is predefined
-and can be looked up through "info/MB/min_bandwidth". The bandwidth
-granularity that is allocated is also dependent on the cpu model and can
-be looked up at "info/MB/bandwidth_gran". The available bandwidth
-control steps are: min_bw + N * bw_gran. Intermediate values are rounded
-to the next control step available on the hardware.
-
-The bandwidth throttling is a core specific mechanism on some of Intel
-SKUs. Using a high bandwidth and a low bandwidth setting on two threads
-sharing a core will result in both threads being throttled to use the
-low bandwidth. The fact that Memory bandwidth allocation(MBA) is a core
-specific mechanism where as memory bandwidth monitoring(MBM) is done at
-the package level may lead to confusion when users try to apply control
-via the MBA and then monitor the bandwidth to see if the controls are
-effective. Below are such scenarios:
-
-1. User may *not* see increase in actual bandwidth when percentage
- values are increased:
-
-This can occur when aggregate L2 external bandwidth is more than L3
-external bandwidth. Consider an SKL SKU with 24 cores on a package and
-where L2 external is 10GBps (hence aggregate L2 external bandwidth is
-240GBps) and L3 external bandwidth is 100GBps. Now a workload with '20
-threads, having 50% bandwidth, each consuming 5GBps' consumes the max L3
-bandwidth of 100GBps although the percentage value specified is only 50%
-<< 100%. Hence increasing the bandwidth percentage will not yeild any
-more bandwidth. This is because although the L2 external bandwidth still
-has capacity, the L3 external bandwidth is fully used. Also note that
-this would be dependent on number of cores the benchmark is run on.
-
-2. Same bandwidth percentage may mean different actual bandwidth
- depending on # of threads:
-
-For the same SKU in #1, a 'single thread, with 10% bandwidth' and '4
-thread, with 10% bandwidth' can consume upto 10GBps and 40GBps although
-they have same percentage bandwidth of 10%. This is simply because as
-threads start using more cores in an rdtgroup, the actual bandwidth may
-increase or vary although user specified bandwidth percentage is same.
-
-In order to mitigate this and make the interface more user friendly,
-resctrl added support for specifying the bandwidth in MBps as well. The
-kernel underneath would use a software feedback mechanism or a "Software
-Controller(mba_sc)" which reads the actual bandwidth using MBM counters
-and adjust the memowy bandwidth percentages to ensure
-
- "actual bandwidth < user specified bandwidth".
-
-By default, the schemata would take the bandwidth percentage values
-where as user can switch to the "MBA software controller" mode using
-a mount option 'mba_MBps'. The schemata format is specified in the below
-sections.
-
-L3 schemata file details (code and data prioritization disabled)
-----------------------------------------------------------------
-With CDP disabled the L3 schemata format is:
-
- L3:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
-
-L3 schemata file details (CDP enabled via mount option to resctrl)
-------------------------------------------------------------------
-When CDP is enabled L3 control is split into two separate resources
-so you can specify independent masks for code and data like this:
-
- L3data:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
- L3code:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
-
-L2 schemata file details
-------------------------
-L2 cache does not support code and data prioritization, so the
-schemata format is always:
-
- L2:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
-
-Memory bandwidth Allocation (default mode)
-------------------------------------------
-
-Memory b/w domain is L3 cache.
-
- MB:<cache_id0>=bandwidth0;<cache_id1>=bandwidth1;...
-
-Memory bandwidth Allocation specified in MBps
----------------------------------------------
-
-Memory bandwidth domain is L3 cache.
-
- MB:<cache_id0>=bw_MBps0;<cache_id1>=bw_MBps1;...
-
-Reading/writing the schemata file
----------------------------------
-Reading the schemata file will show the state of all resources
-on all domains. When writing you only need to specify those values
-which you wish to change. E.g.
-
-# cat schemata
-L3DATA:0=fffff;1=fffff;2=fffff;3=fffff
-L3CODE:0=fffff;1=fffff;2=fffff;3=fffff
-# echo "L3DATA:2=3c0;" > schemata
-# cat schemata
-L3DATA:0=fffff;1=fffff;2=3c0;3=fffff
-L3CODE:0=fffff;1=fffff;2=fffff;3=fffff
-
-Cache Pseudo-Locking
---------------------
-CAT enables a user to specify the amount of cache space that an
-application can fill. Cache pseudo-locking builds on the fact that a
-CPU can still read and write data pre-allocated outside its current
-allocated area on a cache hit. With cache pseudo-locking, data can be
-preloaded into a reserved portion of cache that no application can
-fill, and from that point on will only serve cache hits. The cache
-pseudo-locked memory is made accessible to user space where an
-application can map it into its virtual address space and thus have
-a region of memory with reduced average read latency.
-
-The creation of a cache pseudo-locked region is triggered by a request
-from the user to do so that is accompanied by a schemata of the region
-to be pseudo-locked. The cache pseudo-locked region is created as follows:
-- Create a CAT allocation CLOSNEW with a CBM matching the schemata
- from the user of the cache region that will contain the pseudo-locked
- memory. This region must not overlap with any current CAT allocation/CLOS
- on the system and no future overlap with this cache region is allowed
- while the pseudo-locked region exists.
-- Create a contiguous region of memory of the same size as the cache
- region.
-- Flush the cache, disable hardware prefetchers, disable preemption.
-- Make CLOSNEW the active CLOS and touch the allocated memory to load
- it into the cache.
-- Set the previous CLOS as active.
-- At this point the closid CLOSNEW can be released - the cache
- pseudo-locked region is protected as long as its CBM does not appear in
- any CAT allocation. Even though the cache pseudo-locked region will from
- this point on not appear in any CBM of any CLOS an application running with
- any CLOS will be able to access the memory in the pseudo-locked region since
- the region continues to serve cache hits.
-- The contiguous region of memory loaded into the cache is exposed to
- user-space as a character device.
-
-Cache pseudo-locking increases the probability that data will remain
-in the cache via carefully configuring the CAT feature and controlling
-application behavior. There is no guarantee that data is placed in
-cache. Instructions like INVD, WBINVD, CLFLUSH, etc. can still evict
-“locked†data from cache. Power management C-states may shrink or
-power off cache. Deeper C-states will automatically be restricted on
-pseudo-locked region creation.
-
-It is required that an application using a pseudo-locked region runs
-with affinity to the cores (or a subset of the cores) associated
-with the cache on which the pseudo-locked region resides. A sanity check
-within the code will not allow an application to map pseudo-locked memory
-unless it runs with affinity to cores associated with the cache on which the
-pseudo-locked region resides. The sanity check is only done during the
-initial mmap() handling, there is no enforcement afterwards and the
-application self needs to ensure it remains affine to the correct cores.
-
-Pseudo-locking is accomplished in two stages:
-1) During the first stage the system administrator allocates a portion
- of cache that should be dedicated to pseudo-locking. At this time an
- equivalent portion of memory is allocated, loaded into allocated
- cache portion, and exposed as a character device.
-2) During the second stage a user-space application maps (mmap()) the
- pseudo-locked memory into its address space.
-
-Cache Pseudo-Locking Interface
-------------------------------
-A pseudo-locked region is created using the resctrl interface as follows:
-
-1) Create a new resource group by creating a new directory in /sys/fs/resctrl.
-2) Change the new resource group's mode to "pseudo-locksetup" by writing
- "pseudo-locksetup" to the "mode" file.
-3) Write the schemata of the pseudo-locked region to the "schemata" file. All
- bits within the schemata should be "unused" according to the "bit_usage"
- file.
-
-On successful pseudo-locked region creation the "mode" file will contain
-"pseudo-locked" and a new character device with the same name as the resource
-group will exist in /dev/pseudo_lock. This character device can be mmap()'ed
-by user space in order to obtain access to the pseudo-locked memory region.
-
-An example of cache pseudo-locked region creation and usage can be found below.
-
-Cache Pseudo-Locking Debugging Interface
----------------------------------------
-The pseudo-locking debugging interface is enabled by default (if
-CONFIG_DEBUG_FS is enabled) and can be found in /sys/kernel/debug/resctrl.
-
-There is no explicit way for the kernel to test if a provided memory
-location is present in the cache. The pseudo-locking debugging interface uses
-the tracing infrastructure to provide two ways to measure cache residency of
-the pseudo-locked region:
-1) Memory access latency using the pseudo_lock_mem_latency tracepoint. Data
- from these measurements are best visualized using a hist trigger (see
- example below). In this test the pseudo-locked region is traversed at
- a stride of 32 bytes while hardware prefetchers and preemption
- are disabled. This also provides a substitute visualization of cache
- hits and misses.
-2) Cache hit and miss measurements using model specific precision counters if
- available. Depending on the levels of cache on the system the pseudo_lock_l2
- and pseudo_lock_l3 tracepoints are available.
-
-When a pseudo-locked region is created a new debugfs directory is created for
-it in debugfs as /sys/kernel/debug/resctrl/<newdir>. A single
-write-only file, pseudo_lock_measure, is present in this directory. The
-measurement of the pseudo-locked region depends on the number written to this
-debugfs file:
-1 - writing "1" to the pseudo_lock_measure file will trigger the latency
- measurement captured in the pseudo_lock_mem_latency tracepoint. See
- example below.
-2 - writing "2" to the pseudo_lock_measure file will trigger the L2 cache
- residency (cache hits and misses) measurement captured in the
- pseudo_lock_l2 tracepoint. See example below.
-3 - writing "3" to the pseudo_lock_measure file will trigger the L3 cache
- residency (cache hits and misses) measurement captured in the
- pseudo_lock_l3 tracepoint.
-
-All measurements are recorded with the tracing infrastructure. This requires
-the relevant tracepoints to be enabled before the measurement is triggered.
-
-Example of latency debugging interface:
-In this example a pseudo-locked region named "newlock" was created. Here is
-how we can measure the latency in cycles of reading from this region and
-visualize this data with a histogram that is available if CONFIG_HIST_TRIGGERS
-is set:
-# :> /sys/kernel/debug/tracing/trace
-# echo 'hist:keys=latency' > /sys/kernel/debug/tracing/events/resctrl/pseudo_lock_mem_latency/trigger
-# echo 1 > /sys/kernel/debug/tracing/events/resctrl/pseudo_lock_mem_latency/enable
-# echo 1 > /sys/kernel/debug/resctrl/newlock/pseudo_lock_measure
-# echo 0 > /sys/kernel/debug/tracing/events/resctrl/pseudo_lock_mem_latency/enable
-# cat /sys/kernel/debug/tracing/events/resctrl/pseudo_lock_mem_latency/hist
-
-# event histogram
-#
-# trigger info: hist:keys=latency:vals=hitcount:sort=hitcount:size=2048 [active]
-#
-
-{ latency: 456 } hitcount: 1
-{ latency: 50 } hitcount: 83
-{ latency: 36 } hitcount: 96
-{ latency: 44 } hitcount: 174
-{ latency: 48 } hitcount: 195
-{ latency: 46 } hitcount: 262
-{ latency: 42 } hitcount: 693
-{ latency: 40 } hitcount: 3204
-{ latency: 38 } hitcount: 3484
-
-Totals:
- Hits: 8192
- Entries: 9
- Dropped: 0
-
-Example of cache hits/misses debugging:
-In this example a pseudo-locked region named "newlock" was created on the L2
-cache of a platform. Here is how we can obtain details of the cache hits
-and misses using the platform's precision counters.
-
-# :> /sys/kernel/debug/tracing/trace
-# echo 1 > /sys/kernel/debug/tracing/events/resctrl/pseudo_lock_l2/enable
-# echo 2 > /sys/kernel/debug/resctrl/newlock/pseudo_lock_measure
-# echo 0 > /sys/kernel/debug/tracing/events/resctrl/pseudo_lock_l2/enable

-
-Examples for RDT allocation usage:
-
-Example 1
----------
-On a two socket machine (one L3 cache per socket) with just four bits
-for cache bit masks, minimum b/w of 10% with a memory bandwidth
-granularity of 10%
-
-# mount -t resctrl resctrl /sys/fs/resctrl
-# cd /sys/fs/resctrl
-# mkdir p0 p1
-# echo "L3:0=3;1=c\nMB:0=50;1=50" > /sys/fs/resctrl/p0/schemata
-# echo "L3:0=3;1=3\nMB:0=50;1=50" > /sys/fs/resctrl/p1/schemata
-
-The default resource group is unmodified, so we have access to all parts
-of all caches (its schemata file reads "L3:0=f;1=f").
-
-Tasks that are under the control of group "p0" may only allocate from the
-"lower" 50% on cache ID 0, and the "upper" 50% of cache ID 1.
-Tasks in group "p1" use the "lower" 50% of cache on both sockets.
-
-Similarly, tasks that are under the control of group "p0" may use a
-maximum memory b/w of 50% on socket0 and 50% on socket 1.
-Tasks in group "p1" may also use 50% memory b/w on both sockets.
-Note that unlike cache masks, memory b/w cannot specify whether these
-allocations can overlap or not. The allocations specifies the maximum
-b/w that the group may be able to use and the system admin can configure
-the b/w accordingly.
-
-If the MBA is specified in MB(megabytes) then user can enter the max b/w in MB
-rather than the percentage values.
-
-# echo "L3:0=3;1=c\nMB:0=1024;1=500" > /sys/fs/resctrl/p0/schemata
-# echo "L3:0=3;1=3\nMB:0=1024;1=500" > /sys/fs/resctrl/p1/schemata
-
-In the above example the tasks in "p1" and "p0" on socket 0 would use a max b/w
-of 1024MB where as on socket 1 they would use 500MB.
-
-Example 2
----------
-Again two sockets, but this time with a more realistic 20-bit mask.
-
-Two real time tasks pid=1234 running on processor 0 and pid=5678 running on
-processor 1 on socket 0 on a 2-socket and dual core machine. To avoid noisy
-neighbors, each of the two real-time tasks exclusively occupies one quarter
-of L3 cache on socket 0.
-
-# mount -t resctrl resctrl /sys/fs/resctrl
-# cd /sys/fs/resctrl
-
-First we reset the schemata for the default group so that the "upper"
-50% of the L3 cache on socket 0 and 50% of memory b/w cannot be used by
-ordinary tasks:
-
-# echo "L3:0=3ff;1=fffff\nMB:0=50;1=100" > schemata
-
-Next we make a resource group for our first real time task and give
-it access to the "top" 25% of the cache on socket 0.
-
-# mkdir p0
-# echo "L3:0=f8000;1=fffff" > p0/schemata
-
-Finally we move our first real time task into this resource group. We
-also use taskset(1) to ensure the task always runs on a dedicated CPU
-on socket 0. Most uses of resource groups will also constrain which
-processors tasks run on.
-
-# echo 1234 > p0/tasks
-# taskset -cp 1 1234
-
-Ditto for the second real time task (with the remaining 25% of cache):
-
-# mkdir p1
-# echo "L3:0=7c00;1=fffff" > p1/schemata
-# echo 5678 > p1/tasks
-# taskset -cp 2 5678
-
-For the same 2 socket system with memory b/w resource and CAT L3 the
-schemata would look like(Assume min_bandwidth 10 and bandwidth_gran is
-10):
-
-For our first real time task this would request 20% memory b/w on socket
-0.
-
-# echo -e "L3:0=f8000;1=fffff\nMB:0=20;1=100" > p0/schemata
-
-For our second real time task this would request an other 20% memory b/w
-on socket 0.
-
-# echo -e "L3:0=f8000;1=fffff\nMB:0=20;1=100" > p0/schemata
-
-Example 3
----------
-
-A single socket system which has real-time tasks running on core 4-7 and
-non real-time workload assigned to core 0-3. The real-time tasks share text
-and data, so a per task association is not required and due to interaction
-with the kernel it's desired that the kernel on these cores shares L3 with
-the tasks.
-
-# mount -t resctrl resctrl /sys/fs/resctrl
-# cd /sys/fs/resctrl
-
-First we reset the schemata for the default group so that the "upper"
-50% of the L3 cache on socket 0, and 50% of memory bandwidth on socket 0
-cannot be used by ordinary tasks:
-
-# echo "L3:0=3ff\nMB:0=50" > schemata
-
-Next we make a resource group for our real time cores and give it access
-to the "top" 50% of the cache on socket 0 and 50% of memory bandwidth on
-socket 0.
-
-# mkdir p0
-# echo "L3:0=ffc00\nMB:0=50" > p0/schemata
-
-Finally we move core 4-7 over to the new group and make sure that the
-kernel and the tasks running there get 50% of the cache. They should
-also get 50% of memory bandwidth assuming that the cores 4-7 are SMT
-siblings and only the real time threads are scheduled on the cores 4-7.
-
-# echo F0 > p0/cpus
-
-Example 4
----------
-
-The resource groups in previous examples were all in the default "shareable"
-mode allowing sharing of their cache allocations. If one resource group
-configures a cache allocation then nothing prevents another resource group
-to overlap with that allocation.
-
-In this example a new exclusive resource group will be created on a L2 CAT
-system with two L2 cache instances that can be configured with an 8-bit
-capacity bitmask. The new exclusive resource group will be configured to use
-25% of each cache instance.
-
-# mount -t resctrl resctrl /sys/fs/resctrl/
-# cd /sys/fs/resctrl
-
-First, we observe that the default group is configured to allocate to all L2
-cache:
-
-# cat schemata
-L2:0=ff;1=ff
-
-We could attempt to create the new resource group at this point, but it will
-fail because of the overlap with the schemata of the default group:
-# mkdir p0
-# echo 'L2:0=0x3;1=0x3' > p0/schemata
-# cat p0/mode
-shareable
-# echo exclusive > p0/mode
--sh: echo: write error: Invalid argument
-# cat info/last_cmd_status
-schemata overlaps
-
-To ensure that there is no overlap with another resource group the default
-resource group's schemata has to change, making it possible for the new
-resource group to become exclusive.
-# echo 'L2:0=0xfc;1=0xfc' > schemata
-# echo exclusive > p0/mode
-# grep . p0/*
-p0/cpus:0
-p0/mode:exclusive
-p0/schemata:L2:0=03;1=03
-p0/size:L2:0=262144;1=262144
-
-A new resource group will on creation not overlap with an exclusive resource
-group:
-# mkdir p1
-# grep . p1/*
-p1/cpus:0
-p1/mode:shareable
-p1/schemata:L2:0=fc;1=fc
-p1/size:L2:0=786432;1=786432
-
-The bit_usage will reflect how the cache is used:
-# cat info/L2/bit_usage
-0=SSSSSSEE;1=SSSSSSEE
-
-A resource group cannot be forced to overlap with an exclusive resource group:
-# echo 'L2:0=0x1;1=0x1' > p1/schemata
--sh: echo: write error: Invalid argument
-# cat info/last_cmd_status
-overlaps with exclusive group
-
-Example of Cache Pseudo-Locking
--------------------------------
-Lock portion of L2 cache from cache id 1 using CBM 0x3. Pseudo-locked
-region is exposed at /dev/pseudo_lock/newlock that can be provided to
-application for argument to mmap().
-
-# mount -t resctrl resctrl /sys/fs/resctrl/
-# cd /sys/fs/resctrl
-
-Ensure that there are bits available that can be pseudo-locked, since only
-unused bits can be pseudo-locked the bits to be pseudo-locked needs to be
-removed from the default resource group's schemata:
-# cat info/L2/bit_usage
-0=SSSSSSSS;1=SSSSSSSS
-# echo 'L2:1=0xfc' > schemata
-# cat info/L2/bit_usage
-0=SSSSSSSS;1=SSSSSS00
-
-Create a new resource group that will be associated with the pseudo-locked
-region, indicate that it will be used for a pseudo-locked region, and
-configure the requested pseudo-locked region capacity bitmask:
-
-# mkdir newlock
-# echo pseudo-locksetup > newlock/mode
-# echo 'L2:1=0x3' > newlock/schemata
-

-Locking between applications
-----------------------------
-
-Certain operations on the resctrl filesystem, composed of read/writes
-to/from multiple files, must be atomic.
-
-As an example, the allocation of an exclusive reservation of L3 cache
-involves:
-
- 1. Read the cbmmasks from each directory or the per-resource "bit_usage"
- 2. Find a contiguous set of bits in the global CBM bitmask that is clear
- in any of the directory cbmmasks
- 3. Create a new directory
- 4. Set the bits found in step 2 to the new directory "schemata" file
-
-If two applications attempt to allocate space concurrently then they can
-end up allocating the same bits so the reservations are shared instead of
-exclusive.
-
-To coordinate atomic operations on the resctrlfs and to avoid the problem
-above, the following locking procedure is recommended:
-
-Locking is based on flock, which is available in libc and also as a shell
-script command
-
-Write lock:
-
- A) Take flock(LOCK_EX) on /sys/fs/resctrl
- B) Read/write the directory structure.
- C) funlock
-
-Read lock:
-
- A) Take flock(LOCK_SH) on /sys/fs/resctrl
- B) If success read the directory structure.
- C) funlock
-
-Example with bash:
-
-# Atomically read directory structure
-$ flock -s /sys/fs/resctrl/ find /sys/fs/resctrl
-
-# Read directory contents and create new subdirectory
-
-$ cat create-dir.sh
-find /sys/fs/resctrl/ > output.txt
-mask = function-of(output.txt)
-mkdir /sys/fs/resctrl/newres/
-echo mask > /sys/fs/resctrl/newres/schemata
-
-$ flock /sys/fs/resctrl/ ./create-dir.sh
-
-Example with C:
-
-/*
- * Example code do take advisory locks
- * before accessing resctrl filesystem
- */
-#include <sys/file.h>
-#include <stdlib.h>
-
-void resctrl_take_shared_lock(int fd)
-{
- int ret;
-
- /* take shared lock on resctrl filesystem */
- ret = flock(fd, LOCK_SH);
- if (ret) {
- perror("flock");
- exit(-1);
- }

-
-void resctrl_take_exclusive_lock(int fd)
-{
- int ret;
-
- /* release lock on resctrl filesystem */
- ret = flock(fd, LOCK_EX);

- exit(-1);
- }

-{
- int ret;
-
- /* take shared lock on resctrl filesystem */
- ret = flock(fd, LOCK_UN);
- if (ret) {
- perror("flock");
- exit(-1);
- }
-}
-
-void main(void)
-{
- int fd, ret;
-
- fd = open("/sys/fs/resctrl", O_DIRECTORY);
- if (fd == -1) {
- perror("open");
- exit(-1);
- }
- resctrl_take_shared_lock(fd);
- /* code to read directory contents */

-Examples for RDT Monitoring along with allocation usage:
-
-Reading monitored data
-----------------------
-Reading an event file (for ex: mon_data/mon_L3_00/llc_occupancy) would
-show the current snapshot of LLC occupancy of the corresponding MON
-group or CTRL_MON group.
-
-
-Example 1 (Monitor CTRL_MON group and subset of tasks in CTRL_MON group)
----------
-On a two socket machine (one L3 cache per socket) with just four bits
-for cache bit masks
-
-# mount -t resctrl resctrl /sys/fs/resctrl
-# cd /sys/fs/resctrl
-# mkdir p0 p1
-# echo "L3:0=3;1=c" > /sys/fs/resctrl/p0/schemata
-# echo "L3:0=3;1=3" > /sys/fs/resctrl/p1/schemata
-# echo 5678 > p1/tasks
-# echo 5679 > p1/tasks
-
-The default resource group is unmodified, so we have access to all parts
-of all caches (its schemata file reads "L3:0=f;1=f").
-
-Tasks that are under the control of group "p0" may only allocate from the
-"lower" 50% on cache ID 0, and the "upper" 50% of cache ID 1.
-Tasks in group "p1" use the "lower" 50% of cache on both sockets.
-
-Create monitor groups and assign a subset of tasks to each monitor group.
-
-# cd /sys/fs/resctrl/p1/mon_groups
-# mkdir m11 m12
-# echo 5678 > m11/tasks
-# echo 5679 > m12/tasks
-
-fetch data (data shown in bytes)
-
-# cat m11/mon_data/mon_L3_00/llc_occupancy
-16234000
-# cat m11/mon_data/mon_L3_01/llc_occupancy
-14789000
-# cat m12/mon_data/mon_L3_00/llc_occupancy
-16789000
-
-The parent ctrl_mon group shows the aggregated data.
-
-# cat /sys/fs/resctrl/p1/mon_data/mon_l3_00/llc_occupancy
-31234000
-
-Example 2 (Monitor a task from its creation)
----------
-On a two socket machine (one L3 cache per socket)
-
-# mount -t resctrl resctrl /sys/fs/resctrl
-# cd /sys/fs/resctrl
-# mkdir p0 p1
-
-An RMID is allocated to the group once its created and hence the <cmd>
-below is monitored from its creation.
-
-# echo $$ > /sys/fs/resctrl/p1/tasks
-# <cmd>
-
-Fetch the data
-
-# cat /sys/fs/resctrl/p1/mon_data/mon_l3_00/llc_occupancy
-31789000
-
-Example 3 (Monitor without CAT support or before creating CAT groups)
----------
-
-Assume a system like HSW has only CQM and no CAT support. In this case
-the resctrl will still mount but cannot create CTRL_MON directories.
-But user can create different MON groups within the root group thereby
-able to monitor all tasks including kernel threads.
-
-This can also be used to profile jobs cache size footprint before being
-able to allocate them to different allocation groups.
-
-# mount -t resctrl resctrl /sys/fs/resctrl
-# cd /sys/fs/resctrl
-# mkdir mon_groups/m01
-# mkdir mon_groups/m02
-
-# echo 3478 > /sys/fs/resctrl/mon_groups/m01/tasks
-# echo 2467 > /sys/fs/resctrl/mon_groups/m02/tasks
-
-Monitor the groups separately and also get per domain data. From the
-below its apparent that the tasks are mostly doing work on
-domain(socket) 0.
-
-# cat /sys/fs/resctrl/mon_groups/m01/mon_L3_00/llc_occupancy
-31234000
-# cat /sys/fs/resctrl/mon_groups/m01/mon_L3_01/llc_occupancy
-34555
-# cat /sys/fs/resctrl/mon_groups/m02/mon_L3_00/llc_occupancy
-31234000
-# cat /sys/fs/resctrl/mon_groups/m02/mon_L3_01/llc_occupancy
-32789
-
-
-Example 4 (Monitor real time tasks)
------------------------------------
-
-A single socket system which has real time tasks running on cores 4-7
-and non real time tasks on other cpus. We want to monitor the cache
-occupancy of the real time threads on these cores.
-
-# mount -t resctrl resctrl /sys/fs/resctrl
-# cd /sys/fs/resctrl
-# mkdir p1
-
-Move the cpus 4-7 over to p1
-# echo f0 > p1/cpus
-
-View the llc occupancy snapshot
-
-# cat /sys/fs/resctrl/p1/mon_data/mon_L3_00/llc_occupancy

+User Interface for Resource Control feature
+
+Intel refers to this feature as Intel Resource Director Technology(Intel(R) RDT).
+AMD refers to this feature as AMD Platform Quality of Service(AMD QoS).
+
+Copyright (C) 2016 Intel Corporation
+
+Fenghua Yu <fenghua.yu@intel.com>
+Tony Luck <tony.luck@intel.com>
+Vikas Shivappa <vikas.shivappa@intel.com>
+
+This feature is enabled by the CONFIG_X86_CPU_RESCTRL and the x86 /proc/cpuinfo
+flag bits:
+RDT (Resource Director Technology) Allocation - "rdt_a"
+CAT (Cache Allocation Technology) - "cat_l3", "cat_l2"
+CDP (Code and Data Prioritization ) - "cdp_l3", "cdp_l2"
+CQM (Cache QoS Monitoring) - "cqm_llc", "cqm_occup_llc"
+MBM (Memory Bandwidth Monitoring) - "cqm_mbm_total", "cqm_mbm_local"
+MBA (Memory Bandwidth Allocation) - "mba"
+
+To use the feature mount the file system:
+
+ # mount -t resctrl resctrl [-o cdp[,cdpl2][,mba_MBps]] /sys/fs/resctrl
+
+mount options are:
+
+"cdp": Enable code/data prioritization in L3 cache allocations.
+"cdpl2": Enable code/data prioritization in L2 cache allocations.
+"mba_MBps": Enable the MBA Software Controller(mba_sc) to specify MBA
+ bandwidth in MBps
+
+L2 and L3 CDP are controlled seperately.
+
+RDT features are orthogonal. A particular system may support only
+monitoring, only control, or both monitoring and control. Cache
+pseudo-locking is a unique way of using cache control to "pin" or
+"lock" data in the cache. Details can be found in
+"Cache Pseudo-Locking".
+
+
+The mount succeeds if either of allocation or monitoring is present, but
+only those files and directories supported by the system will be created.
+For more details on the behavior of the interface during monitoring
+and allocation, see the "Resource alloc and monitor groups" section.
+
+Info directory
+--------------
+
+The 'info' directory contains information about the enabled
+resources. Each resource has its own subdirectory. The subdirectory
+names reflect the resource names.
+
+Each subdirectory contains the following files with respect to
+allocation:
+
+Cache resource(L3/L2) subdirectory contains the following files
+related to allocation:
+
+"num_closids": The number of CLOSIDs which are valid for this
+ resource. The kernel uses the smallest number of
+ CLOSIDs of all enabled resources as limit.
+
+"cbm_mask": The bitmask which is valid for this resource.
+ This mask is equivalent to 100%.
+
+"min_cbm_bits": The minimum number of consecutive bits which
+ must be set when writing a mask.
+
+"shareable_bits": Bitmask of shareable resource with other executing
+ entities (e.g. I/O). User can use this when
+ setting up exclusive cache partitions. Note that
+ some platforms support devices that have their
+ own settings for cache use which can over-ride
+ these bits.
+"bit_usage": Annotated capacity bitmasks showing how all
+ instances of the resource are used. The legend is:
+ "0" - Corresponding region is unused. When the system's
+ resources have been allocated and a "0" is found
+ in "bit_usage" it is a sign that resources are
+ wasted.
+ "H" - Corresponding region is used by hardware only
+ but available for software use. If a resource
+ has bits set in "shareable_bits" but not all
+ of these bits appear in the resource groups'
+ schematas then the bits appearing in
+ "shareable_bits" but no resource group will
+ be marked as "H".
+ "X" - Corresponding region is available for sharing and
+ used by hardware and software. These are the
+ bits that appear in "shareable_bits" as
+ well as a resource group's allocation.
+ "S" - Corresponding region is used by software
+ and available for sharing.
+ "E" - Corresponding region is used exclusively by
+ one resource group. No sharing allowed.
+ "P" - Corresponding region is pseudo-locked. No
+ sharing allowed.
+
+Memory bandwitdh(MB) subdirectory contains the following files
+with respect to allocation:
+
+"min_bandwidth": The minimum memory bandwidth percentage which
+ user can request.
+
+"bandwidth_gran": The granularity in which the memory bandwidth
+ percentage is allocated. The allocated
+ b/w percentage is rounded off to the next
+ control step available on the hardware. The
+ available bandwidth control steps are:
+ min_bandwidth + N * bandwidth_gran.
+
+"delay_linear": Indicates if the delay scale is linear or
+ non-linear. This field is purely informational
+ only.
+
+If RDT monitoring is available there will be an "L3_MON" directory
+with the following files:
+
+"num_rmids": The number of RMIDs available. This is the
+ upper bound for how many "CTRL_MON" + "MON"
+ groups can be created.
+
+"mon_features": Lists the monitoring events if
+ monitoring is enabled for the resource.
+
+"max_threshold_occupancy":
+ Read/write file provides the largest value (in
+ bytes) at which a previously used LLC_occupancy
+ counter can be considered for re-use.
+
+Finally, in the top level of the "info" directory there is a file
+named "last_cmd_status". This is reset with every "command" issued
+via the file system (making new directories or writing to any of the
+control files). If the command was successful, it will read as "ok".
+If the command failed, it will provide more information that can be
+conveyed in the error returns from file operations. E.g.
+
+ # echo L3:0=f7 > schemata
+ bash: echo: write error: Invalid argument
+ # cat info/last_cmd_status
+ mask f7 has non-consecutive 1-bits
+
+Resource alloc and monitor groups
+---------------------------------
+
+Resource groups are represented as directories in the resctrl file
+system. The default group is the root directory which, immediately
+after mounting, owns all the tasks and cpus in the system and can make
+full use of all resources.
+
+On a system with RDT control features additional directories can be
+created in the root directory that specify different amounts of each
+resource (see "schemata" below). The root and these additional top level
+directories are referred to as "CTRL_MON" groups below.
+
+On a system with RDT monitoring the root directory and other top level
+directories contain a directory named "mon_groups" in which additional
+directories can be created to monitor subsets of tasks in the CTRL_MON
+group that is their ancestor. These are called "MON" groups in the rest
+of this document.
+
+Removing a directory will move all tasks and cpus owned by the group it
+represents to the parent. Removing one of the created CTRL_MON groups
+will automatically remove all MON groups below it.
+
+All groups contain the following files:
+
+"tasks":
+ Reading this file shows the list of all tasks that belong to
+ this group. Writing a task id to the file will add a task to the
+ group. If the group is a CTRL_MON group the task is removed from
+ whichever previous CTRL_MON group owned the task and also from
+ any MON group that owned the task. If the group is a MON group,
+ then the task must already belong to the CTRL_MON parent of this
+ group. The task is removed from any previous MON group.
+
+
+"cpus":
+ Reading this file shows a bitmask of the logical CPUs owned by
+ this group. Writing a mask to this file will add and remove
+ CPUs to/from this group. As with the tasks file a hierarchy is
+ maintained where MON groups may only include CPUs owned by the
+ parent CTRL_MON group.
+ When the resouce group is in pseudo-locked mode this file will
+ only be readable, reflecting the CPUs associated with the
+ pseudo-locked region.
+
+
+"cpus_list":
+ Just like "cpus", only using ranges of CPUs instead of bitmasks.
+
+
+When control is enabled all CTRL_MON groups will also contain:
+
+"schemata":
+ A list of all the resources available to this group.
+ Each resource has its own line and format - see below for details.
+
+"size":
+ Mirrors the display of the "schemata" file to display the size in
+ bytes of each allocation instead of the bits representing the
+ allocation.
+
+"mode":
+ The "mode" of the resource group dictates the sharing of its
+ allocations. A "shareable" resource group allows sharing of its
+ allocations while an "exclusive" resource group does not. A
+ cache pseudo-locked region is created by first writing
+ "pseudo-locksetup" to the "mode" file before writing the cache
+ pseudo-locked region's schemata to the resource group's "schemata"
+ file. On successful pseudo-locked region creation the mode will
+ automatically change to "pseudo-locked".
+
+When monitoring is enabled all MON groups will also contain:
+
+"mon_data":
+ This contains a set of files organized by L3 domain and by
+ RDT event. E.g. on a system with two L3 domains there will
+ be subdirectories "mon_L3_00" and "mon_L3_01". Each of these
+ directories have one file per event (e.g. "llc_occupancy",
+ "mbm_total_bytes", and "mbm_local_bytes"). In a MON group these
+ files provide a read out of the current value of the event for
+ all tasks in the group. In CTRL_MON groups these files provide
+ the sum for all tasks in the CTRL_MON group and all tasks in
+ MON groups. Please see example section for more details on usage.
+
+Resource allocation rules
+-------------------------
+When a task is running the following rules define which resources are
+available to it:
+
+1) If the task is a member of a non-default group, then the schemata
+ for that group is used.
+
+2) Else if the task belongs to the default group, but is running on a
+ CPU that is assigned to some specific group, then the schemata for the
+ CPU's group is used.
+
+3) Otherwise the schemata for the default group is used.
+
+Resource monitoring rules
+-------------------------
+1) If a task is a member of a MON group, or non-default CTRL_MON group
+ then RDT events for the task will be reported in that group.
+
+2) If a task is a member of the default CTRL_MON group, but is running
+ on a CPU that is assigned to some specific group, then the RDT events
+ for the task will be reported in that group.
+
+3) Otherwise RDT events for the task will be reported in the root level
+ "mon_data" group.
+
+
+Notes on cache occupancy monitoring and control
+-----------------------------------------------
+When moving a task from one group to another you should remember that
+this only affects *new* cache allocations by the task. E.g. you may have
+a task in a monitor group showing 3 MB of cache occupancy. If you move
+to a new group and immediately check the occupancy of the old and new
+groups you will likely see that the old group is still showing 3 MB and
+the new group zero. When the task accesses locations still in cache from
+before the move, the h/w does not update any counters. On a busy system
+you will likely see the occupancy in the old group go down as cache lines
+are evicted and re-used while the occupancy in the new group rises as
+the task accesses memory and loads into the cache are counted based on
+membership in the new group.
+
+The same applies to cache allocation control. Moving a task to a group
+with a smaller cache partition will not evict any cache lines. The
+process may continue to use them from the old partition.
+
+Hardware uses CLOSid(Class of service ID) and an RMID(Resource monitoring ID)
+to identify a control group and a monitoring group respectively. Each of
+the resource groups are mapped to these IDs based on the kind of group. The
+number of CLOSid and RMID are limited by the hardware and hence the creation of
+a "CTRL_MON" directory may fail if we run out of either CLOSID or RMID
+and creation of "MON" group may fail if we run out of RMIDs.
+
+max_threshold_occupancy - generic concepts
+------------------------------------------
+
+Note that an RMID once freed may not be immediately available for use as
+the RMID is still tagged the cache lines of the previous user of RMID.
+Hence such RMIDs are placed on limbo list and checked back if the cache
+occupancy has gone down. If there is a time when system has a lot of
+limbo RMIDs but which are not ready to be used, user may see an -EBUSY
+during mkdir.
+
+max_threshold_occupancy is a user configurable value to determine the
+occupancy at which an RMID can be freed.
+
+Schemata files - general concepts
+---------------------------------
+Each line in the file describes one resource. The line starts with
+the name of the resource, followed by specific values to be applied
+in each of the instances of that resource on the system.
+
+Cache IDs
+---------
+On current generation systems there is one L3 cache per socket and L2
+caches are generally just shared by the hyperthreads on a core, but this
+isn't an architectural requirement. We could have multiple separate L3
+caches on a socket, multiple cores could share an L2 cache. So instead
+of using "socket" or "core" to define the set of logical cpus sharing
+a resource we use a "Cache ID". At a given cache level this will be a
+unique number across the whole system (but it isn't guaranteed to be a
+contiguous sequence, there may be gaps). To find the ID for each logical
+CPU look in /sys/devices/system/cpu/cpu*/cache/index*/id
+
+Cache Bit Masks (CBM)
+---------------------
+For cache resources we describe the portion of the cache that is available
+for allocation using a bitmask. The maximum value of the mask is defined
+by each cpu model (and may be different for different cache levels). It
+is found using CPUID, but is also provided in the "info" directory of
+the resctrl file system in "info/{resource}/cbm_mask". X86 hardware
+requires that these masks have all the '1' bits in a contiguous block. So
+0x3, 0x6 and 0xC are legal 4-bit masks with two bits set, but 0x5, 0x9
+and 0xA are not. On a system with a 20-bit mask each bit represents 5%
+of the capacity of the cache. You could partition the cache into four
+equal parts with masks: 0x1f, 0x3e0, 0x7c00, 0xf8000.
+
+Memory bandwidth Allocation and monitoring
+------------------------------------------
+
+For Memory bandwidth resource, by default the user controls the resource
+by indicating the percentage of total memory bandwidth.
+
+The minimum bandwidth percentage value for each cpu model is predefined
+and can be looked up through "info/MB/min_bandwidth". The bandwidth
+granularity that is allocated is also dependent on the cpu model and can
+be looked up at "info/MB/bandwidth_gran". The available bandwidth
+control steps are: min_bw + N * bw_gran. Intermediate values are rounded
+to the next control step available on the hardware.
+
+The bandwidth throttling is a core specific mechanism on some of Intel
+SKUs. Using a high bandwidth and a low bandwidth setting on two threads
+sharing a core will result in both threads being throttled to use the
+low bandwidth. The fact that Memory bandwidth allocation(MBA) is a core
+specific mechanism where as memory bandwidth monitoring(MBM) is done at
+the package level may lead to confusion when users try to apply control
+via the MBA and then monitor the bandwidth to see if the controls are
+effective. Below are such scenarios:
+
+1. User may *not* see increase in actual bandwidth when percentage
+ values are increased:
+
+This can occur when aggregate L2 external bandwidth is more than L3
+external bandwidth. Consider an SKL SKU with 24 cores on a package and
+where L2 external is 10GBps (hence aggregate L2 external bandwidth is
+240GBps) and L3 external bandwidth is 100GBps. Now a workload with '20
+threads, having 50% bandwidth, each consuming 5GBps' consumes the max L3
+bandwidth of 100GBps although the percentage value specified is only 50%
+<< 100%. Hence increasing the bandwidth percentage will not yeild any
+more bandwidth. This is because although the L2 external bandwidth still
+has capacity, the L3 external bandwidth is fully used. Also note that
+this would be dependent on number of cores the benchmark is run on.
+
+2. Same bandwidth percentage may mean different actual bandwidth
+ depending on # of threads:
+
+For the same SKU in #1, a 'single thread, with 10% bandwidth' and '4
+thread, with 10% bandwidth' can consume upto 10GBps and 40GBps although
+they have same percentage bandwidth of 10%. This is simply because as
+threads start using more cores in an rdtgroup, the actual bandwidth may
+increase or vary although user specified bandwidth percentage is same.
+
+In order to mitigate this and make the interface more user friendly,
+resctrl added support for specifying the bandwidth in MBps as well. The
+kernel underneath would use a software feedback mechanism or a "Software
+Controller(mba_sc)" which reads the actual bandwidth using MBM counters
+and adjust the memowy bandwidth percentages to ensure
+
+ "actual bandwidth < user specified bandwidth".
+
+By default, the schemata would take the bandwidth percentage values
+where as user can switch to the "MBA software controller" mode using
+a mount option 'mba_MBps'. The schemata format is specified in the below
+sections.

+
+ L3:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
+
+L3 schemata file details (CDP enabled via mount option to resctrl)
+------------------------------------------------------------------
+When CDP is enabled L3 control is split into two separate resources
+so you can specify independent masks for code and data like this:
+
+ L3data:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
+ L3code:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
+
+L2 schemata file details
+------------------------
+L2 cache does not support code and data prioritization, so the
+schemata format is always:
+
+ L2:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
+
+Memory bandwidth Allocation (default mode)
+------------------------------------------
+
+Memory b/w domain is L3 cache.
+
+ MB:<cache_id0>=bandwidth0;<cache_id1>=bandwidth1;...
+
+Memory bandwidth Allocation specified in MBps
+---------------------------------------------
+
+Memory bandwidth domain is L3 cache.
+
+ MB:<cache_id0>=bw_MBps0;<cache_id1>=bw_MBps1;...
+
+Reading/writing the schemata file
+---------------------------------
+Reading the schemata file will show the state of all resources
+on all domains. When writing you only need to specify those values
+which you wish to change. E.g.
+
+# cat schemata
+L3DATA:0=fffff;1=fffff;2=fffff;3=fffff
+L3CODE:0=fffff;1=fffff;2=fffff;3=fffff
+# echo "L3DATA:2=3c0;" > schemata
+# cat schemata
+L3DATA:0=fffff;1=fffff;2=3c0;3=fffff
+L3CODE:0=fffff;1=fffff;2=fffff;3=fffff
+
+Cache Pseudo-Locking
+--------------------
+CAT enables a user to specify the amount of cache space that an
+application can fill. Cache pseudo-locking builds on the fact that a
+CPU can still read and write data pre-allocated outside its current
+allocated area on a cache hit. With cache pseudo-locking, data can be
+preloaded into a reserved portion of cache that no application can
+fill, and from that point on will only serve cache hits. The cache
+pseudo-locked memory is made accessible to user space where an
+application can map it into its virtual address space and thus have
+a region of memory with reduced average read latency.
+
+The creation of a cache pseudo-locked region is triggered by a request
+from the user to do so that is accompanied by a schemata of the region
+to be pseudo-locked. The cache pseudo-locked region is created as follows:
+- Create a CAT allocation CLOSNEW with a CBM matching the schemata
+ from the user of the cache region that will contain the pseudo-locked
+ memory. This region must not overlap with any current CAT allocation/CLOS
+ on the system and no future overlap with this cache region is allowed
+ while the pseudo-locked region exists.
+- Create a contiguous region of memory of the same size as the cache
+ region.
+- Flush the cache, disable hardware prefetchers, disable preemption.
+- Make CLOSNEW the active CLOS and touch the allocated memory to load
+ it into the cache.
+- Set the previous CLOS as active.
+- At this point the closid CLOSNEW can be released - the cache
+ pseudo-locked region is protected as long as its CBM does not appear in
+ any CAT allocation. Even though the cache pseudo-locked region will from
+ this point on not appear in any CBM of any CLOS an application running with
+ any CLOS will be able to access the memory in the pseudo-locked region since
+ the region continues to serve cache hits.
+- The contiguous region of memory loaded into the cache is exposed to
+ user-space as a character device.
+
+Cache pseudo-locking increases the probability that data will remain
+in the cache via carefully configuring the CAT feature and controlling
+application behavior. There is no guarantee that data is placed in
+cache. Instructions like INVD, WBINVD, CLFLUSH, etc. can still evict
+“locked†data from cache. Power management C-states may shrink or
+power off cache. Deeper C-states will automatically be restricted on
+pseudo-locked region creation.
+
+It is required that an application using a pseudo-locked region runs
+with affinity to the cores (or a subset of the cores) associated
+with the cache on which the pseudo-locked region resides. A sanity check
+within the code will not allow an application to map pseudo-locked memory
+unless it runs with affinity to cores associated with the cache on which the
+pseudo-locked region resides. The sanity check is only done during the
+initial mmap() handling, there is no enforcement afterwards and the
+application self needs to ensure it remains affine to the correct cores.
+
+Pseudo-locking is accomplished in two stages:
+1) During the first stage the system administrator allocates a portion
+ of cache that should be dedicated to pseudo-locking. At this time an
+ equivalent portion of memory is allocated, loaded into allocated
+ cache portion, and exposed as a character device.
+2) During the second stage a user-space application maps (mmap()) the
+ pseudo-locked memory into its address space.
+
+Cache Pseudo-Locking Interface
+------------------------------
+A pseudo-locked region is created using the resctrl interface as follows:
+
+1) Create a new resource group by creating a new directory in /sys/fs/resctrl.
+2) Change the new resource group's mode to "pseudo-locksetup" by writing
+ "pseudo-locksetup" to the "mode" file.
+3) Write the schemata of the pseudo-locked region to the "schemata" file. All
+ bits within the schemata should be "unused" according to the "bit_usage"
+ file.
+
+On successful pseudo-locked region creation the "mode" file will contain
+"pseudo-locked" and a new character device with the same name as the resource
+group will exist in /dev/pseudo_lock. This character device can be mmap()'ed
+by user space in order to obtain access to the pseudo-locked memory region.
+
+An example of cache pseudo-locked region creation and usage can be found below.
+
+Cache Pseudo-Locking Debugging Interface
+---------------------------------------
+The pseudo-locking debugging interface is enabled by default (if
+CONFIG_DEBUG_FS is enabled) and can be found in /sys/kernel/debug/resctrl.
+
+There is no explicit way for the kernel to test if a provided memory
+location is present in the cache. The pseudo-locking debugging interface uses
+the tracing infrastructure to provide two ways to measure cache residency of
+the pseudo-locked region:
+1) Memory access latency using the pseudo_lock_mem_latency tracepoint. Data
+ from these measurements are best visualized using a hist trigger (see
+ example below). In this test the pseudo-locked region is traversed at
+ a stride of 32 bytes while hardware prefetchers and preemption
+ are disabled. This also provides a substitute visualization of cache
+ hits and misses.
+2) Cache hit and miss measurements using model specific precision counters if
+ available. Depending on the levels of cache on the system the pseudo_lock_l2
+ and pseudo_lock_l3 tracepoints are available.
+
+When a pseudo-locked region is created a new debugfs directory is created for
+it in debugfs as /sys/kernel/debug/resctrl/<newdir>. A single
+write-only file, pseudo_lock_measure, is present in this directory. The
+measurement of the pseudo-locked region depends on the number written to this
+debugfs file:
+1 - writing "1" to the pseudo_lock_measure file will trigger the latency
+ measurement captured in the pseudo_lock_mem_latency tracepoint. See
+ example below.
+2 - writing "2" to the pseudo_lock_measure file will trigger the L2 cache
+ residency (cache hits and misses) measurement captured in the
+ pseudo_lock_l2 tracepoint. See example below.
+3 - writing "3" to the pseudo_lock_measure file will trigger the L3 cache
+ residency (cache hits and misses) measurement captured in the
+ pseudo_lock_l3 tracepoint.
+
+All measurements are recorded with the tracing infrastructure. This requires
+the relevant tracepoints to be enabled before the measurement is triggered.
+
+Example of latency debugging interface:
+In this example a pseudo-locked region named "newlock" was created. Here is
+how we can measure the latency in cycles of reading from this region and
+visualize this data with a histogram that is available if CONFIG_HIST_TRIGGERS
+is set:
+# :> /sys/kernel/debug/tracing/trace
+# echo 'hist:keys=latency' > /sys/kernel/debug/tracing/events/resctrl/pseudo_lock_mem_latency/trigger
+# echo 1 > /sys/kernel/debug/tracing/events/resctrl/pseudo_lock_mem_latency/enable
+# echo 1 > /sys/kernel/debug/resctrl/newlock/pseudo_lock_measure
+# echo 0 > /sys/kernel/debug/tracing/events/resctrl/pseudo_lock_mem_latency/enable
+# cat /sys/kernel/debug/tracing/events/resctrl/pseudo_lock_mem_latency/hist
+
+# event histogram
+#
+# trigger info: hist:keys=latency:vals=hitcount:sort=hitcount:size=2048 [active]
+#
+
+{ latency: 456 } hitcount: 1
+{ latency: 50 } hitcount: 83
+{ latency: 36 } hitcount: 96
+{ latency: 44 } hitcount: 174
+{ latency: 48 } hitcount: 195
+{ latency: 46 } hitcount: 262
+{ latency: 42 } hitcount: 693
+{ latency: 40 } hitcount: 3204
+{ latency: 38 } hitcount: 3484
+
+Totals:
+ Hits: 8192
+ Entries: 9
+ Dropped: 0
+
+Example of cache hits/misses debugging:
+In this example a pseudo-locked region named "newlock" was created on the L2
+cache of a platform. Here is how we can obtain details of the cache hits
+and misses using the platform's precision counters.
+
+# :> /sys/kernel/debug/tracing/trace
+# echo 1 > /sys/kernel/debug/tracing/events/resctrl/pseudo_lock_l2/enable

+
+
+Examples for RDT allocation usage:
+
+Example 1
+---------
+On a two socket machine (one L3 cache per socket) with just four bits
+for cache bit masks, minimum b/w of 10% with a memory bandwidth
+granularity of 10%
+
+# mount -t resctrl resctrl /sys/fs/resctrl
+# cd /sys/fs/resctrl
+# mkdir p0 p1
+# echo "L3:0=3;1=c\nMB:0=50;1=50" > /sys/fs/resctrl/p0/schemata
+# echo "L3:0=3;1=3\nMB:0=50;1=50" > /sys/fs/resctrl/p1/schemata
+
+The default resource group is unmodified, so we have access to all parts
+of all caches (its schemata file reads "L3:0=f;1=f").
+
+Tasks that are under the control of group "p0" may only allocate from the
+"lower" 50% on cache ID 0, and the "upper" 50% of cache ID 1.
+Tasks in group "p1" use the "lower" 50% of cache on both sockets.
+
+Similarly, tasks that are under the control of group "p0" may use a
+maximum memory b/w of 50% on socket0 and 50% on socket 1.
+Tasks in group "p1" may also use 50% memory b/w on both sockets.
+Note that unlike cache masks, memory b/w cannot specify whether these
+allocations can overlap or not. The allocations specifies the maximum
+b/w that the group may be able to use and the system admin can configure
+the b/w accordingly.
+
+If the MBA is specified in MB(megabytes) then user can enter the max b/w in MB
+rather than the percentage values.
+
+# echo "L3:0=3;1=c\nMB:0=1024;1=500" > /sys/fs/resctrl/p0/schemata
+# echo "L3:0=3;1=3\nMB:0=1024;1=500" > /sys/fs/resctrl/p1/schemata
+
+In the above example the tasks in "p1" and "p0" on socket 0 would use a max b/w
+of 1024MB where as on socket 1 they would use 500MB.
+
+Example 2
+---------
+Again two sockets, but this time with a more realistic 20-bit mask.
+
+Two real time tasks pid=1234 running on processor 0 and pid=5678 running on
+processor 1 on socket 0 on a 2-socket and dual core machine. To avoid noisy
+neighbors, each of the two real-time tasks exclusively occupies one quarter
+of L3 cache on socket 0.
+
+# mount -t resctrl resctrl /sys/fs/resctrl
+# cd /sys/fs/resctrl
+
+First we reset the schemata for the default group so that the "upper"
+50% of the L3 cache on socket 0 and 50% of memory b/w cannot be used by
+ordinary tasks:
+
+# echo "L3:0=3ff;1=fffff\nMB:0=50;1=100" > schemata
+
+Next we make a resource group for our first real time task and give
+it access to the "top" 25% of the cache on socket 0.
+
+# mkdir p0
+# echo "L3:0=f8000;1=fffff" > p0/schemata
+
+Finally we move our first real time task into this resource group. We
+also use taskset(1) to ensure the task always runs on a dedicated CPU
+on socket 0. Most uses of resource groups will also constrain which
+processors tasks run on.
+
+# echo 1234 > p0/tasks
+# taskset -cp 1 1234
+
+Ditto for the second real time task (with the remaining 25% of cache):
+
+# mkdir p1
+# echo "L3:0=7c00;1=fffff" > p1/schemata
+# echo 5678 > p1/tasks
+# taskset -cp 2 5678
+
+For the same 2 socket system with memory b/w resource and CAT L3 the
+schemata would look like(Assume min_bandwidth 10 and bandwidth_gran is
+10):
+
+For our first real time task this would request 20% memory b/w on socket
+0.
+
+# echo -e "L3:0=f8000;1=fffff\nMB:0=20;1=100" > p0/schemata
+
+For our second real time task this would request an other 20% memory b/w
+on socket 0.
+
+# echo -e "L3:0=f8000;1=fffff\nMB:0=20;1=100" > p0/schemata
+
+Example 3
+---------
+
+A single socket system which has real-time tasks running on core 4-7 and
+non real-time workload assigned to core 0-3. The real-time tasks share text
+and data, so a per task association is not required and due to interaction
+with the kernel it's desired that the kernel on these cores shares L3 with
+the tasks.
+
+# mount -t resctrl resctrl /sys/fs/resctrl
+# cd /sys/fs/resctrl
+
+First we reset the schemata for the default group so that the "upper"
+50% of the L3 cache on socket 0, and 50% of memory bandwidth on socket 0
+cannot be used by ordinary tasks:
+
+# echo "L3:0=3ff\nMB:0=50" > schemata
+
+Next we make a resource group for our real time cores and give it access
+to the "top" 50% of the cache on socket 0 and 50% of memory bandwidth on
+socket 0.
+
+# mkdir p0
+# echo "L3:0=ffc00\nMB:0=50" > p0/schemata
+
+Finally we move core 4-7 over to the new group and make sure that the
+kernel and the tasks running there get 50% of the cache. They should
+also get 50% of memory bandwidth assuming that the cores 4-7 are SMT
+siblings and only the real time threads are scheduled on the cores 4-7.
+
+# echo F0 > p0/cpus
+
+Example 4
+---------
+
+The resource groups in previous examples were all in the default "shareable"
+mode allowing sharing of their cache allocations. If one resource group
+configures a cache allocation then nothing prevents another resource group
+to overlap with that allocation.
+
+In this example a new exclusive resource group will be created on a L2 CAT
+system with two L2 cache instances that can be configured with an 8-bit
+capacity bitmask. The new exclusive resource group will be configured to use
+25% of each cache instance.
+
+# mount -t resctrl resctrl /sys/fs/resctrl/
+# cd /sys/fs/resctrl
+
+First, we observe that the default group is configured to allocate to all L2
+cache:
+
+# cat schemata
+L2:0=ff;1=ff
+
+We could attempt to create the new resource group at this point, but it will
+fail because of the overlap with the schemata of the default group:
+# mkdir p0
+# echo 'L2:0=0x3;1=0x3' > p0/schemata
+# cat p0/mode
+shareable
+# echo exclusive > p0/mode
+-sh: echo: write error: Invalid argument
+# cat info/last_cmd_status
+schemata overlaps
+
+To ensure that there is no overlap with another resource group the default
+resource group's schemata has to change, making it possible for the new
+resource group to become exclusive.
+# echo 'L2:0=0xfc;1=0xfc' > schemata
+# echo exclusive > p0/mode
+# grep . p0/*
+p0/cpus:0
+p0/mode:exclusive
+p0/schemata:L2:0=03;1=03
+p0/size:L2:0=262144;1=262144
+
+A new resource group will on creation not overlap with an exclusive resource
+group:
+# mkdir p1
+# grep . p1/*
+p1/cpus:0
+p1/mode:shareable
+p1/schemata:L2:0=fc;1=fc
+p1/size:L2:0=786432;1=786432
+
+The bit_usage will reflect how the cache is used:
+# cat info/L2/bit_usage
+0=SSSSSSEE;1=SSSSSSEE
+
+A resource group cannot be forced to overlap with an exclusive resource group:
+# echo 'L2:0=0x1;1=0x1' > p1/schemata
+-sh: echo: write error: Invalid argument
+# cat info/last_cmd_status
+overlaps with exclusive group
+
+Example of Cache Pseudo-Locking
+-------------------------------
+Lock portion of L2 cache from cache id 1 using CBM 0x3. Pseudo-locked
+region is exposed at /dev/pseudo_lock/newlock that can be provided to
+application for argument to mmap().
+
+# mount -t resctrl resctrl /sys/fs/resctrl/
+# cd /sys/fs/resctrl
+
+Ensure that there are bits available that can be pseudo-locked, since only
+unused bits can be pseudo-locked the bits to be pseudo-locked needs to be
+removed from the default resource group's schemata:
+# cat info/L2/bit_usage
+0=SSSSSSSS;1=SSSSSSSS
+# echo 'L2:1=0xfc' > schemata
+# cat info/L2/bit_usage
+0=SSSSSSSS;1=SSSSSS00
+
+Create a new resource group that will be associated with the pseudo-locked
+region, indicate that it will be used for a pseudo-locked region, and
+configure the requested pseudo-locked region capacity bitmask:
+
+# mkdir newlock
+# echo pseudo-locksetup > newlock/mode
+# echo 'L2:1=0x3' > newlock/schemata
+
+On success the resource group's mode will change to pseudo-locked, the
+bit_usage will reflect the pseudo-locked region, and the character device
+exposing the pseudo-locked region will exist:
+
+# cat newlock/mode
+pseudo-locked
+# cat info/L2/bit_usage
+0=SSSSSSSS;1=SSSSSSPP
+# ls -l /dev/pseudo_lock/newlock
+crw------- 1 root root 243, 0 Apr 3 05:01 /dev/pseudo_lock/newlock

+
+Locking between applications
+----------------------------
+
+Certain operations on the resctrl filesystem, composed of read/writes
+to/from multiple files, must be atomic.
+
+As an example, the allocation of an exclusive reservation of L3 cache
+involves:
+
+ 1. Read the cbmmasks from each directory or the per-resource "bit_usage"
+ 2. Find a contiguous set of bits in the global CBM bitmask that is clear
+ in any of the directory cbmmasks
+ 3. Create a new directory
+ 4. Set the bits found in step 2 to the new directory "schemata" file
+
+If two applications attempt to allocate space concurrently then they can
+end up allocating the same bits so the reservations are shared instead of
+exclusive.
+
+To coordinate atomic operations on the resctrlfs and to avoid the problem
+above, the following locking procedure is recommended:
+
+Locking is based on flock, which is available in libc and also as a shell
+script command
+
+Write lock:
+
+ A) Take flock(LOCK_EX) on /sys/fs/resctrl
+ B) Read/write the directory structure.
+ C) funlock
+
+Read lock:
+
+ A) Take flock(LOCK_SH) on /sys/fs/resctrl
+ B) If success read the directory structure.
+ C) funlock
+
+Example with bash:
+
+# Atomically read directory structure
+$ flock -s /sys/fs/resctrl/ find /sys/fs/resctrl
+
+# Read directory contents and create new subdirectory
+
+$ cat create-dir.sh
+find /sys/fs/resctrl/ > output.txt
+mask = function-of(output.txt)
+mkdir /sys/fs/resctrl/newres/
+echo mask > /sys/fs/resctrl/newres/schemata
+
+$ flock /sys/fs/resctrl/ ./create-dir.sh
+
+Example with C:
+
+/*
+ * Example code do take advisory locks
+ * before accessing resctrl filesystem
+ */
+#include <sys/file.h>
+#include <stdlib.h>
+
+void resctrl_take_shared_lock(int fd)
+{
+ int ret;
+
+ /* take shared lock on resctrl filesystem */
+ ret = flock(fd, LOCK_SH);
+ if (ret) {
+ perror("flock");
+ exit(-1);
+ }
+}
+
+void resctrl_take_exclusive_lock(int fd)
+{
+ int ret;
+
+ /* release lock on resctrl filesystem */
+ ret = flock(fd, LOCK_EX);
+ if (ret) {
+ perror("flock");
+ exit(-1);
+ }
+}
+
+void resctrl_release_lock(int fd)
+{
+ int ret;
+
+ /* take shared lock on resctrl filesystem */
+ ret = flock(fd, LOCK_UN);
+ if (ret) {
+ perror("flock");
+ exit(-1);
+ }
+}
+
+void main(void)
+{
+ int fd, ret;
+
+ fd = open("/sys/fs/resctrl", O_DIRECTORY);
+ if (fd == -1) {
+ perror("open");
+ exit(-1);
+ }
+ resctrl_take_shared_lock(fd);
+ /* code to read directory contents */
+ resctrl_release_lock(fd);
+
+ resctrl_take_exclusive_lock(fd);
+ /* code to read and write directory contents */
+ resctrl_release_lock(fd);
+}
+
+Examples for RDT Monitoring along with allocation usage:
+
+Reading monitored data
+----------------------
+Reading an event file (for ex: mon_data/mon_L3_00/llc_occupancy) would
+show the current snapshot of LLC occupancy of the corresponding MON
+group or CTRL_MON group.
+
+
+Example 1 (Monitor CTRL_MON group and subset of tasks in CTRL_MON group)
+---------
+On a two socket machine (one L3 cache per socket) with just four bits
+for cache bit masks
+
+# mount -t resctrl resctrl /sys/fs/resctrl
+# cd /sys/fs/resctrl
+# mkdir p0 p1
+# echo "L3:0=3;1=c" > /sys/fs/resctrl/p0/schemata
+# echo "L3:0=3;1=3" > /sys/fs/resctrl/p1/schemata
+# echo 5678 > p1/tasks
+# echo 5679 > p1/tasks
+
+The default resource group is unmodified, so we have access to all parts
+of all caches (its schemata file reads "L3:0=f;1=f").
+
+Tasks that are under the control of group "p0" may only allocate from the
+"lower" 50% on cache ID 0, and the "upper" 50% of cache ID 1.
+Tasks in group "p1" use the "lower" 50% of cache on both sockets.
+
+Create monitor groups and assign a subset of tasks to each monitor group.
+
+# cd /sys/fs/resctrl/p1/mon_groups
+# mkdir m11 m12
+# echo 5678 > m11/tasks
+# echo 5679 > m12/tasks
+
+fetch data (data shown in bytes)
+
+# cat m11/mon_data/mon_L3_00/llc_occupancy
+16234000

+The parent ctrl_mon group shows the aggregated data.
+
+# cat /sys/fs/resctrl/p1/mon_data/mon_l3_00/llc_occupancy

+
+Example 2 (Monitor a task from its creation)
+---------
+On a two socket machine (one L3 cache per socket)
+
+# mount -t resctrl resctrl /sys/fs/resctrl
+# cd /sys/fs/resctrl
+# mkdir p0 p1
+
+An RMID is allocated to the group once its created and hence the <cmd>
+below is monitored from its creation.
+
+# echo $$ > /sys/fs/resctrl/p1/tasks
+# <cmd>
+
+Fetch the data
+
+# cat /sys/fs/resctrl/p1/mon_data/mon_l3_00/llc_occupancy
+31789000
+
+Example 3 (Monitor without CAT support or before creating CAT groups)
+---------
+
+Assume a system like HSW has only CQM and no CAT support. In this case
+the resctrl will still mount but cannot create CTRL_MON directories.
+But user can create different MON groups within the root group thereby
+able to monitor all tasks including kernel threads.
+
+This can also be used to profile jobs cache size footprint before being
+able to allocate them to different allocation groups.
+
+# mount -t resctrl resctrl /sys/fs/resctrl
+# cd /sys/fs/resctrl
+# mkdir mon_groups/m01
+# mkdir mon_groups/m02
+
+# echo 3478 > /sys/fs/resctrl/mon_groups/m01/tasks
+# echo 2467 > /sys/fs/resctrl/mon_groups/m02/tasks
+
+Monitor the groups separately and also get per domain data. From the
+below its apparent that the tasks are mostly doing work on
+domain(socket) 0.
+
+# cat /sys/fs/resctrl/mon_groups/m01/mon_L3_00/llc_occupancy
+31234000
+# cat /sys/fs/resctrl/mon_groups/m01/mon_L3_01/llc_occupancy

+# cat /sys/fs/resctrl/mon_groups/m02/mon_L3_00/llc_occupancy
+31234000
+# cat /sys/fs/resctrl/mon_groups/m02/mon_L3_01/llc_occupancy
+32789
+
+
+Example 4 (Monitor real time tasks)
+-----------------------------------
+
+A single socket system which has real time tasks running on cores 4-7
+and non real time tasks on other cpus. We want to monitor the cache
+occupancy of the real time threads on these cores.
+
+# mount -t resctrl resctrl /sys/fs/resctrl
+# cd /sys/fs/resctrl
+# mkdir p1
+
+Move the cpus 4-7 over to p1
+# echo f0 > p1/cpus
+
+View the llc occupancy snapshot
+
+# cat /sys/fs/resctrl/p1/mon_data/mon_L3_00/llc_occupancy

+Passing boot parameters to the kernel.
+
+Boot parameters are represented as a TLV list in the memory. Please see
+arch/xtensa/include/asm/bootparam.h for definition of the bp_tag structure and
+tag value constants. First entry in the list must have type BP_TAG_FIRST, last
+entry must have type BP_TAG_LAST. The address of the first list entry is
+passed to the kernel in the register a2. The address type depends on MMU type:
+- For configurations without MMU, with region protection or with MPU the
+ address must be the physical address.
+- For configurations with region translarion MMU or with MMUv3 and CONFIG_MMU=n
+ the address must be a valid address in the current mapping. The kernel will
+ not change the mapping on its own.
+- For configurations with MMUv2 the address must be a virtual address in the
+ default virtual mapping (0xd0000000..0xffffffff).
+- For configurations with MMUv3 and CONFIG_MMU=y the address may be either a
+ virtual or physical address. In either case it must be within the default
+ virtual mapping. It is considered physical if it is within the range of
+ physical addresses covered by the default KSEG mapping (XCHAL_KSEG_PADDR..
+ XCHAL_KSEG_PADDR + XCHAL_KSEG_SIZE), otherwise it is considered virtual.

- PCI is the name of a bus system, i.e., the way the CPU talks to
- the other stuff inside your box. Find out if your board/platform
- has PCI.
-
- Note: PCIe support for Synopsys Device will be available only
- when HAPS DX is configured with PCIe RC bitmap. If you have PCI,
- say Y, otherwise N.

Use optimized AES assembler routines for ARM platforms.
+ On ARM processors without the Crypto Extensions, this is the
+ fastest AES implementation for single blocks. For multiple
+ blocks, the NEON bit-sliced implementation is usually faster.
+
+ This implementation may be vulnerable to cache timing attacks,
+ since it uses lookup tables. However, as countermeasures it
+ disables IRQs and preloads the tables; it is hoped this makes
+ such attacks very difficult.

- * NEON doesn't have a rotate instruction. The alternatives are, more or less:
- *
- * (a) vshl.u32 + vsri.u32 (needs temporary register)
- * (b) vshl.u32 + vshr.u32 + vorr (needs temporary register)
- * (c) vrev32.16 (16-bit rotations only)
- * (d) vtbl.8 + vtbl.8 (multiple of 8 bits rotations only,
- * needs index vector)
- *
- * ChaCha20 has 16, 12, 8, and 7-bit rotations. For the 12 and 7-bit
- * rotations, the only choices are (a) and (b). We use (a) since it takes
- * two-thirds the cycles of (b) on both Cortex-A7 and Cortex-A53.
- *
- * For the 16-bit rotation, we use vrev32.16 since it's consistently fastest
- * and doesn't need a temporary register.
- *
- * For the 8-bit rotation, we use vtbl.8 + vtbl.8. On Cortex-A7, this sequence
- * is twice as fast as (a), even when doing (a) on multiple registers
- * simultaneously to eliminate the stall between vshl and vsri. Also, it
- * parallelizes better when temporary registers are scarce.
- *
- * A disadvantage is that on Cortex-A53, the vtbl sequence is the same speed as
- * (a), so the need to load the rotation table actually makes the vtbl method
- * slightly slower overall on that CPU (~1.3% slower ChaCha20). Still, it
- * seems to be a good compromise to get a more significant speed boost on some
- * CPUs, e.g. ~4.8% faster ChaCha20 on Cortex-A7.

+ * The hardware supports concatenation of up to 16 tables at stage2 entry
+ * level and we use the feature whenever possible, which means we resolve 4
+ * additional bits of address at the entry level.
*
- * Now, the minimum number of bits resolved at any level is (PAGE_SHIFT - 3).
- * On arm64, the smallest PAGE_SIZE supported is 4k, which means
- * (PAGE_SHIFT - 3) > 4 holds for all page sizes.
- * This implies, the total number of page table levels at stage2 expected
- * by the hardware is actually the number of levels required for (IPA_SHIFT - 4)
- * in normal translations(e.g, stage1), since we cannot have another level in
- * the range (IPA_SHIFT, IPA_SHIFT - 4).
+ * This implies, the total number of page table levels required for
+ * IPA_SHIFT at stage2 expected by the hardware can be calculated using
+ * the same logic used for the (non-collapsable) stage1 page tables but for
+ * (IPA_SHIFT - 4).

+ * Some Loongson 3 CPUs have a bug wherein execution of a memory access (load,
+ * store or pref) in between an ll & sc can cause the sc instruction to
+ * erroneously succeed, breaking atomicity. Whilst it's unusual to write code
+ * containing such sequences, this bug bites harder than we might otherwise
+ * expect due to reordering & speculation:
+ *
+ * 1) A memory access appearing prior to the ll in program order may actually
+ * be executed after the ll - this is the reordering case.
+ *
+ * In order to avoid this we need to place a memory barrier (ie. a sync
+ * instruction) prior to every ll instruction, in between it & any earlier
+ * memory access instructions. Many of these cases are already covered by
+ * smp_mb__before_llsc() but for the remaining cases, typically ones in
+ * which multiple CPUs may operate on a memory location but ordering is not
+ * usually guaranteed, we use loongson_llsc_mb() below.
+ *
+ * This reordering case is fixed by 3A R2 CPUs, ie. 3A2000 models and later.
+ *
+ * 2) If a conditional branch exists between an ll & sc with a target outside
+ * of the ll-sc loop, for example an exit upon value mismatch in cmpxchg()
+ * or similar, then misprediction of the branch may allow speculative
+ * execution of memory accesses from outside of the ll-sc loop.
+ *
+ * In order to avoid this we need a memory barrier (ie. a sync instruction)
+ * at each affected branch target, for which we also use loongson_llsc_mb()
+ * defined below.
+ *

- # This function encrypts eight consecutive ChaCha20 blocks by loading
- # the state matrix in AVX registers eight times. As we need some
- # scratch registers, we save the first four registers on the stack. The
- # algorithm performs each operation on the corresponding word of each
- # state matrix, hence requires no word shuffling. For final XORing step
- # we transpose the matrix by interleaving 32-, 64- and then 128-bit
- # words, which allows us to do XOR in AVX registers. 8/16-bit word
- # rotation is done with the slightly better performing byte shuffling,
- # 7/12-bit word rotation uses traditional shift+OR.

- # This function encrypts four consecutive ChaCha20 blocks by loading the
- # the state matrix in SSE registers four times. As we need some scratch
- # registers, we save the first four registers on the stack. The
- # algorithm performs each operation on the corresponding word of each
- # state matrix, hence requires no word shuffling. For final XORing step
- # we transpose the matrix by interleaving 32- and then 64-bit words,
- # which allows us to do XOR in SSE registers. 8/16-bit word rotation is
- # done with the slightly better performing SSSE3 byte shuffling,
- # 7/12-bit word rotation uses traditional shift+OR.

- * Feedback loop for MBA software controller (mba_sc)
- *
- * mba_sc is a feedback loop where we periodically read MBM counters and
- * adjust the bandwidth percentage values via the IA32_MBA_THRTL_MSRs so
- * that:
- *
- * current bandwdith(cur_bw) < user specified bandwidth(user_bw)
- *
- * This uses the MBM counters to measure the bandwidth and MBA throttle
- * MSRs to control the bandwidth for a particular rdtgrp. It builds on the
- * fact that resctrl rdtgroups have both monitoring and control.
- *
- * The frequency of the checks is 1s and we just tag along the MBM overflow
- * timer. Having 1s interval makes the calculation of bandwidth simpler.
- *
- * Although MBA's goal is to restrict the bandwidth to a maximum, there may
- * be a need to increase the bandwidth to avoid uncecessarily restricting
- * the L2 <-> L3 traffic.
- *
- * Since MBA controls the L2 external bandwidth where as MBM measures the
- * L3 external bandwidth the following sequence could lead to such a
- * situation.
- *
- * Consider an rdtgroup which had high L3 <-> memory traffic in initial
- * phases -> mba_sc kicks in and reduced bandwidth percentage values -> but
- * after some time rdtgroup has mostly L2 <-> L3 traffic.
- *
- * In this case we may restrict the rdtgroup's L2 <-> L3 traffic as its
- * throttle MSRs already have low percentage values. To avoid
- * unnecessarily restricting such rdtgroups, we also increase the bandwidth.
