+ Set this to 'Y' to change the network device link
+ framing from '802.3' to 'raw-ip'.
+
+ The netdev will change to reflect the link framing
+ mode. The netdev is an ordinary ethernet device in
+ '802.3' mode, and the driver expects to exchange
+ frames with an ethernet header over the USB link. The
+ netdev is a headerless p-t-p device in 'raw-ip' mode,
+ and the driver expects to echange IPv4 or IPv6 packets
+ without any L2 header over the USB link.
+
+ Userspace is in full control of firmware configuration
+ through the delegation of the QMI protocol. Userspace
+ is responsible for coordination of driver and firmware
+ link framing mode, changing this setting to 'Y' if the
+ firmware is configured for 'raw-ip' mode.

- any new rendering to the frame buffer until the page flip completes.

- operation.
- </para>
- <para>
- After locating the appropriate encoders, the helper function will
- call the <methodname>mode_fixup</methodname> encoder and CRTC helper
- operations to adjust the requested mode, or reject it completely in
- which case an error will be returned to the application. If the new
- configuration after mode adjustment is identical to the current

- the adjusted mode differs from the current mode, or if the

- provided, the helper function performs a full mode set sequence by

- flows from the entity's output to one or more entity inputs. Pads should not
- be confused with physical pins at chip boundaries.</para>

-
-Writeback
-=========
-
-Page cache is dirtied through buffered writes and shared mmaps and
-written asynchronously to the backing filesystem by the writeback
-mechanism. Writeback sits between the memory and IO domains and
-regulates the proportion of dirty memory by balancing dirtying and
-write IOs.
-
-On traditional cgroup hierarchies, relationships between different
-controllers cannot be established making it impossible for writeback
-to operate accounting for cgroup resource restrictions and all
-writeback IOs are attributed to the root cgroup.
-
-If both the blkio and memory controllers are used on the v2 hierarchy
-and the filesystem supports cgroup writeback, writeback operations
-correctly follow the resource restrictions imposed by both memory and
-blkio controllers.
-
-Writeback examines both system-wide and per-cgroup dirty memory status
-and enforces the more restrictive of the two. Also, writeback control
-parameters which are absolute values - vm.dirty_bytes and
-vm.dirty_background_bytes - are distributed across cgroups according
-to their current writeback bandwidth.
-
-There's a peculiarity stemming from the discrepancy in ownership
-granularity between memory controller and writeback. While memory
-controller tracks ownership per page, writeback operates on inode
-basis. cgroup writeback bridges the gap by tracking ownership by
-inode but migrating ownership if too many foreign pages, pages which
-don't match the current inode ownership, have been encountered while
-writing back the inode.
-
-This is a conscious design choice as writeback operations are
-inherently tied to inodes making strictly following page ownership
-complicated and inefficient. The only use case which suffers from
-this compromise is multiple cgroups concurrently dirtying disjoint
-regions of the same inode, which is an unlikely use case and decided
-to be unsupported. Note that as memory controller assigns page
-ownership on the first use and doesn't update it until the page is
-released, even if cgroup writeback strictly follows page ownership,
-multiple cgroups dirtying overlapping areas wouldn't work as expected.
-In general, write-sharing an inode across multiple cgroups is not well
-supported.
-
-Filesystem support for cgroup writeback
----------------------------------------
-
-A filesystem can make writeback IOs cgroup-aware by updating
-address_space_operations->writepage[s]() to annotate bio's using the
-following two functions.
-
-* wbc_init_bio(@wbc, @bio)
-
- Should be called for each bio carrying writeback data and associates
- the bio with the inode's owner cgroup. Can be called anytime
- between bio allocation and submission.
-
-* wbc_account_io(@wbc, @page, @bytes)
-
- Should be called for each data segment being written out. While
- this function doesn't care exactly when it's called during the
- writeback session, it's the easiest and most natural to call it as
- data segments are added to a bio.
-
-With writeback bio's annotated, cgroup support can be enabled per
-super_block by setting MS_CGROUPWB in ->s_flags. This allows for
-selective disabling of cgroup writeback support which is helpful when
-certain filesystem features, e.g. journaled data mode, are
-incompatible.
-
-wbc_init_bio() binds the specified bio to its cgroup. Depending on
-the configuration, the bio may be executed at a lower priority and if
-the writeback session is holding shared resources, e.g. a journal
-entry, may lead to priority inversion. There is no one easy solution
-for the problem. Filesystems can try to work around specific problem
-cases by skipping wbc_init_bio() or using bio_associate_blkcg()
-directly.

+1. Introduction
+
+1-1. Terminology
+
+"cgroup" stands for "control group" and is never capitalized. The
+singular form is used to designate the whole feature and also as a
+qualifier as in "cgroup controllers". When explicitly referring to
+multiple individual control groups, the plural form "cgroups" is used.
+
+
+1-2. What is cgroup?
+
+cgroup is a mechanism to organize processes hierarchically and
+distribute system resources along the hierarchy in a controlled and
+configurable manner.
+
+cgroup is largely composed of two parts - the core and controllers.
+cgroup core is primarily responsible for hierarchically organizing
+processes. A cgroup controller is usually responsible for
+distributing a specific type of system resource along the hierarchy
+although there are utility controllers which serve purposes other than
+resource distribution.
+
+cgroups form a tree structure and every process in the system belongs
+to one and only one cgroup. All threads of a process belong to the
+same cgroup. On creation, all processes are put in the cgroup that
+the parent process belongs to at the time. A process can be migrated
+to another cgroup. Migration of a process doesn't affect already
+existing descendant processes.
+
+Following certain structural constraints, controllers may be enabled or
+disabled selectively on a cgroup. All controller behaviors are
+hierarchical - if a controller is enabled on a cgroup, it affects all
+processes which belong to the cgroups consisting the inclusive
+sub-hierarchy of the cgroup. When a controller is enabled on a nested
+cgroup, it always restricts the resource distribution further. The
+restrictions set closer to the root in the hierarchy can not be
+overridden from further away.
+
+
+2. Basic Operations
+
+2-1. Mounting
+
+Unlike v1, cgroup v2 has only single hierarchy. The cgroup v2
+hierarchy can be mounted with the following mount command.
+
+ # mount -t cgroup2 none $MOUNT_POINT
+
+cgroup2 filesystem has the magic number 0x63677270 ("cgrp"). All
+controllers which support v2 and are not bound to a v1 hierarchy are
+automatically bound to the v2 hierarchy and show up at the root.
+Controllers which are not in active use in the v2 hierarchy can be
+bound to other hierarchies. This allows mixing v2 hierarchy with the
+legacy v1 multiple hierarchies in a fully backward compatible way.
+
+A controller can be moved across hierarchies only after the controller
+is no longer referenced in its current hierarchy. Because per-cgroup
+controller states are destroyed asynchronously and controllers may
+have lingering references, a controller may not show up immediately on
+the v2 hierarchy after the final umount of the previous hierarchy.
+Similarly, a controller should be fully disabled to be moved out of
+the unified hierarchy and it may take some time for the disabled
+controller to become available for other hierarchies; furthermore, due
+to inter-controller dependencies, other controllers may need to be
+disabled too.
+
+While useful for development and manual configurations, moving
+controllers dynamically between the v2 and other hierarchies is
+strongly discouraged for production use. It is recommended to decide
+the hierarchies and controller associations before starting using the
+controllers after system boot.
+
+
+2-2. Organizing Processes
+
+Initially, only the root cgroup exists to which all processes belong.
+A child cgroup can be created by creating a sub-directory.
+
+ # mkdir $CGROUP_NAME
+
+A given cgroup may have multiple child cgroups forming a tree
+structure. Each cgroup has a read-writable interface file
+"cgroup.procs". When read, it lists the PIDs of all processes which
+belong to the cgroup one-per-line. The PIDs are not ordered and the
+same PID may show up more than once if the process got moved to
+another cgroup and then back or the PID got recycled while reading.
+
+A process can be migrated into a cgroup by writing its PID to the
+target cgroup's "cgroup.procs" file. Only one process can be migrated
+on a single write(2) call. If a process is composed of multiple
+threads, writing the PID of any thread migrates all threads of the
+process.
+
+When a process forks a child process, the new process is born into the
+cgroup that the forking process belongs to at the time of the
+operation. After exit, a process stays associated with the cgroup
+that it belonged to at the time of exit until it's reaped; however, a
+zombie process does not appear in "cgroup.procs" and thus can't be
+moved to another cgroup.
+
+A cgroup which doesn't have any children or live processes can be
+destroyed by removing the directory. Note that a cgroup which doesn't
+have any children and is associated only with zombie processes is
+considered empty and can be removed.
+
+ # rmdir $CGROUP_NAME
+
+"/proc/$PID/cgroup" lists a process's cgroup membership. If legacy
+cgroup is in use in the system, this file may contain multiple lines,
+one for each hierarchy. The entry for cgroup v2 is always in the
+format "0::$PATH".
+
+ # cat /proc/842/cgroup
+ ...
+ 0::/test-cgroup/test-cgroup-nested
+
+If the process becomes a zombie and the cgroup it was associated with
+is removed subsequently, " (deleted)" is appended to the path.
+
+ # cat /proc/842/cgroup
+ ...
+ 0::/test-cgroup/test-cgroup-nested (deleted)
+
+
+2-3. [Un]populated Notification
+
+Each non-root cgroup has a "cgroup.events" file which contains
+"populated" field indicating whether the cgroup's sub-hierarchy has
+live processes in it. Its value is 0 if there is no live process in
+the cgroup and its descendants; otherwise, 1. poll and [id]notify
+events are triggered when the value changes. This can be used, for
+example, to start a clean-up operation after all processes of a given
+sub-hierarchy have exited. The populated state updates and
+notifications are recursive. Consider the following sub-hierarchy
+where the numbers in the parentheses represent the numbers of processes
+in each cgroup.
+
+ A(4) - B(0) - C(1)
+ \ D(0)
+
+A, B and C's "populated" fields would be 1 while D's 0. After the one
+process in C exits, B and C's "populated" fields would flip to "0" and
+file modified events will be generated on the "cgroup.events" files of
+both cgroups.
+
+
+2-4. Controlling Controllers
+
+2-4-1. Enabling and Disabling
+
+Each cgroup has a "cgroup.controllers" file which lists all
+controllers available for the cgroup to enable.
+
+ # cat cgroup.controllers
+ cpu io memory
+
+No controller is enabled by default. Controllers can be enabled and
+disabled by writing to the "cgroup.subtree_control" file.
+
+ # echo "+cpu +memory -io" > cgroup.subtree_control
+
+Only controllers which are listed in "cgroup.controllers" can be
+enabled. When multiple operations are specified as above, either they
+all succeed or fail. If multiple operations on the same controller
+are specified, the last one is effective.
+
+Enabling a controller in a cgroup indicates that the distribution of
+the target resource across its immediate children will be controlled.
+Consider the following sub-hierarchy. The enabled controllers are
+listed in parentheses.
+
+ A(cpu,memory) - B(memory) - C()
+ \ D()
+
+As A has "cpu" and "memory" enabled, A will control the distribution
+of CPU cycles and memory to its children, in this case, B. As B has
+"memory" enabled but not "CPU", C and D will compete freely on CPU
+cycles but their division of memory available to B will be controlled.
+
+As a controller regulates the distribution of the target resource to
+the cgroup's children, enabling it creates the controller's interface
+files in the child cgroups. In the above example, enabling "cpu" on B
+would create the "cpu." prefixed controller interface files in C and
+D. Likewise, disabling "memory" from B would remove the "memory."
+prefixed controller interface files from C and D. This means that the
+controller interface files - anything which doesn't start with
+"cgroup." are owned by the parent rather than the cgroup itself.
+
+
+2-4-2. Top-down Constraint
+
+Resources are distributed top-down and a cgroup can further distribute
+a resource only if the resource has been distributed to it from the
+parent. This means that all non-root "cgroup.subtree_control" files
+can only contain controllers which are enabled in the parent's
+"cgroup.subtree_control" file. A controller can be enabled only if
+the parent has the controller enabled and a controller can't be
+disabled if one or more children have it enabled.
+
+
+2-4-3. No Internal Process Constraint
+
+Non-root cgroups can only distribute resources to their children when
+they don't have any processes of their own. In other words, only
+cgroups which don't contain any processes can have controllers enabled
+in their "cgroup.subtree_control" files.
+
+This guarantees that, when a controller is looking at the part of the
+hierarchy which has it enabled, processes are always only on the
+leaves. This rules out situations where child cgroups compete against
+internal processes of the parent.
+
+The root cgroup is exempt from this restriction. Root contains
+processes and anonymous resource consumption which can't be associated
+with any other cgroups and requires special treatment from most
+controllers. How resource consumption in the root cgroup is governed
+is up to each controller.
+
+Note that the restriction doesn't get in the way if there is no
+enabled controller in the cgroup's "cgroup.subtree_control". This is
+important as otherwise it wouldn't be possible to create children of a
+populated cgroup. To control resource distribution of a cgroup, the
+cgroup must create children and transfer all its processes to the
+children before enabling controllers in its "cgroup.subtree_control"
+file.
+
+
+2-5. Delegation
+
+2-5-1. Model of Delegation
+
+A cgroup can be delegated to a less privileged user by granting write
+access of the directory and its "cgroup.procs" file to the user. Note
+that resource control interface files in a given directory control the
+distribution of the parent's resources and thus must not be delegated
+along with the directory.
+
+Once delegated, the user can build sub-hierarchy under the directory,
+organize processes as it sees fit and further distribute the resources
+it received from the parent. The limits and other settings of all
+resource controllers are hierarchical and regardless of what happens
+in the delegated sub-hierarchy, nothing can escape the resource
+restrictions imposed by the parent.
+
+Currently, cgroup doesn't impose any restrictions on the number of
+cgroups in or nesting depth of a delegated sub-hierarchy; however,
+this may be limited explicitly in the future.
+
+
+2-5-2. Delegation Containment
+
+A delegated sub-hierarchy is contained in the sense that processes
+can't be moved into or out of the sub-hierarchy by the delegatee. For
+a process with a non-root euid to migrate a target process into a
+cgroup by writing its PID to the "cgroup.procs" file, the following
+conditions must be met.
+
+- The writer's euid must match either uid or suid of the target process.
+
+- The writer must have write access to the "cgroup.procs" file.
+
+- The writer must have write access to the "cgroup.procs" file of the
+ common ancestor of the source and destination cgroups.
+
+The above three constraints ensure that while a delegatee may migrate
+processes around freely in the delegated sub-hierarchy it can't pull
+in from or push out to outside the sub-hierarchy.
+
+For an example, let's assume cgroups C0 and C1 have been delegated to
+user U0 who created C00, C01 under C0 and C10 under C1 as follows and
+all processes under C0 and C1 belong to U0.
+
+ ~~~~~~~~~~~~~ - C0 - C00
+ ~ cgroup ~ \ C01
+ ~ hierarchy ~
+ ~~~~~~~~~~~~~ - C1 - C10
+
+Let's also say U0 wants to write the PID of a process which is
+currently in C10 into "C00/cgroup.procs". U0 has write access to the
+file and uid match on the process; however, the common ancestor of the
+source cgroup C10 and the destination cgroup C00 is above the points
+of delegation and U0 would not have write access to its "cgroup.procs"
+files and thus the write will be denied with -EACCES.
+
+
+2-6. Guidelines
+
+2-6-1. Organize Once and Control
+
+Migrating a process across cgroups is a relatively expensive operation
+and stateful resources such as memory are not moved together with the
+process. This is an explicit design decision as there often exist
+inherent trade-offs between migration and various hot paths in terms
+of synchronization cost.
+
+As such, migrating processes across cgroups frequently as a means to
+apply different resource restrictions is discouraged. A workload
+should be assigned to a cgroup according to the system's logical and
+resource structure once on start-up. Dynamic adjustments to resource
+distribution can be made by changing controller configuration through
+the interface files.
+
+
+2-6-2. Avoid Name Collisions
+
+Interface files for a cgroup and its children cgroups occupy the same
+directory and it is possible to create children cgroups which collide
+with interface files.
+
+All cgroup core interface files are prefixed with "cgroup." and each
+controller's interface files are prefixed with the controller name and
+a dot. A controller's name is composed of lower case alphabets and
+'_'s but never begins with an '_' so it can be used as the prefix
+character for collision avoidance. Also, interface file names won't
+start or end with terms which are often used in categorizing workloads
+such as job, service, slice, unit or workload.
+
+cgroup doesn't do anything to prevent name collisions and it's the
+user's responsibility to avoid them.
+
+
+3. Resource Distribution Models
+
+cgroup controllers implement several resource distribution schemes
+depending on the resource type and expected use cases. This section
+describes major schemes in use along with their expected behaviors.
+
+
+3-1. Weights
+
+A parent's resource is distributed by adding up the weights of all
+active children and giving each the fraction matching the ratio of its
+weight against the sum. As only children which can make use of the
+resource at the moment participate in the distribution, this is
+work-conserving. Due to the dynamic nature, this model is usually
+used for stateless resources.
+
+All weights are in the range [1, 10000] with the default at 100. This
+allows symmetric multiplicative biases in both directions at fine
+enough granularity while staying in the intuitive range.
+
+As long as the weight is in range, all configuration combinations are
+valid and there is no reason to reject configuration changes or
+process migrations.
+
+"cpu.weight" proportionally distributes CPU cycles to active children
+and is an example of this type.
+
+
+3-2. Limits
+
+A child can only consume upto the configured amount of the resource.
+Limits can be over-committed - the sum of the limits of children can
+exceed the amount of resource available to the parent.
+
+Limits are in the range [0, max] and defaults to "max", which is noop.
+
+As limits can be over-committed, all configuration combinations are
+valid and there is no reason to reject configuration changes or
+process migrations.
+
+"io.max" limits the maximum BPS and/or IOPS that a cgroup can consume
+on an IO device and is an example of this type.
+
+
+3-3. Protections
+
+A cgroup is protected to be allocated upto the configured amount of
+the resource if the usages of all its ancestors are under their
+protected levels. Protections can be hard guarantees or best effort
+soft boundaries. Protections can also be over-committed in which case
+only upto the amount available to the parent is protected among
+children.
+
+Protections are in the range [0, max] and defaults to 0, which is
+noop.
+
+As protections can be over-committed, all configuration combinations
+are valid and there is no reason to reject configuration changes or
+process migrations.
+
+"memory.low" implements best-effort memory protection and is an
+example of this type.
+
+
+3-4. Allocations
+
+A cgroup is exclusively allocated a certain amount of a finite
+resource. Allocations can't be over-committed - the sum of the
+allocations of children can not exceed the amount of resource
+available to the parent.
+
+Allocations are in the range [0, max] and defaults to 0, which is no
+resource.
+
+As allocations can't be over-committed, some configuration
+combinations are invalid and should be rejected. Also, if the
+resource is mandatory for execution of processes, process migrations
+may be rejected.
+
+"cpu.rt.max" hard-allocates realtime slices and is an example of this
+type.
+
+
+4. Interface Files
+
+4-1. Format
+
+All interface files should be in one of the following formats whenever
+possible.
+
+ New-line separated values
+ (when only one value can be written at once)
+
+ VAL0\n
+ VAL1\n
+ ...
+
+ Space separated values
+ (when read-only or multiple values can be written at once)
+
+ VAL0 VAL1 ...\n
+
+ Flat keyed
+
+ KEY0 VAL0\n
+ KEY1 VAL1\n
+ ...
+
+ Nested keyed
+
+ KEY0 SUB_KEY0=VAL00 SUB_KEY1=VAL01...
+ KEY1 SUB_KEY0=VAL10 SUB_KEY1=VAL11...
+ ...
+
+For a writable file, the format for writing should generally match
+reading; however, controllers may allow omitting later fields or
+implement restricted shortcuts for most common use cases.
+
+For both flat and nested keyed files, only the values for a single key
+can be written at a time. For nested keyed files, the sub key pairs
+may be specified in any order and not all pairs have to be specified.
+
+
+4-2. Conventions
+
+- Settings for a single feature should be contained in a single file.
+
+- The root cgroup should be exempt from resource control and thus
+ shouldn't have resource control interface files. Also,
+ informational files on the root cgroup which end up showing global
+ information available elsewhere shouldn't exist.
+
+- If a controller implements weight based resource distribution, its
+ interface file should be named "weight" and have the range [1,
+ 10000] with 100 as the default. The values are chosen to allow
+ enough and symmetric bias in both directions while keeping it
+ intuitive (the default is 100%).
+
+- If a controller implements an absolute resource guarantee and/or
+ limit, the interface files should be named "min" and "max"
+ respectively. If a controller implements best effort resource
+ guarantee and/or limit, the interface files should be named "low"
+ and "high" respectively.
+
+ In the above four control files, the special token "max" should be
+ used to represent upward infinity for both reading and writing.
+
+- If a setting has a configurable default value and keyed specific
+ overrides, the default entry should be keyed with "default" and
+ appear as the first entry in the file.
+
+ The default value can be updated by writing either "default $VAL" or
+ "$VAL".
+
+ When writing to update a specific override, "default" can be used as
+ the value to indicate removal of the override. Override entries
+ with "default" as the value must not appear when read.
+
+ For example, a setting which is keyed by major:minor device numbers
+ with integer values may look like the following.
+
+ # cat cgroup-example-interface-file
+ default 150
+ 8:0 300
+
+ The default value can be updated by
+
+ # echo 125 > cgroup-example-interface-file
+
+ or
+
+ # echo "default 125" > cgroup-example-interface-file
+
+ An override can be set by
+
+ # echo "8:16 170" > cgroup-example-interface-file
+
+ and cleared by
+
+ # echo "8:0 default" > cgroup-example-interface-file
+ # cat cgroup-example-interface-file
+ default 125
+ 8:16 170
+
+- For events which are not very high frequency, an interface file
+ "events" should be created which lists event key value pairs.
+ Whenever a notifiable event happens, file modified event should be
+ generated on the file.
+
+
+4-3. Core Interface Files
+
+All cgroup core files are prefixed with "cgroup."
+
+ cgroup.procs
+
+ A read-write new-line separated values file which exists on
+ all cgroups.
+
+ When read, it lists the PIDs of all processes which belong to
+ the cgroup one-per-line. The PIDs are not ordered and the
+ same PID may show up more than once if the process got moved
+ to another cgroup and then back or the PID got recycled while
+ reading.
+
+ A PID can be written to migrate the process associated with
+ the PID to the cgroup. The writer should match all of the
+ following conditions.
+
+ - Its euid is either root or must match either uid or suid of
+ the target process.
+
+ - It must have write access to the "cgroup.procs" file.
+
+ - It must have write access to the "cgroup.procs" file of the
+ common ancestor of the source and destination cgroups.
+
+ When delegating a sub-hierarchy, write access to this file
+ should be granted along with the containing directory.
+
+ cgroup.controllers
+
+ A read-only space separated values file which exists on all
+ cgroups.
+
+ It shows space separated list of all controllers available to
+ the cgroup. The controllers are not ordered.
+
+ cgroup.subtree_control
+
+ A read-write space separated values file which exists on all
+ cgroups. Starts out empty.
+
+ When read, it shows space separated list of the controllers
+ which are enabled to control resource distribution from the
+ cgroup to its children.
+
+ Space separated list of controllers prefixed with '+' or '-'
+ can be written to enable or disable controllers. A controller
+ name prefixed with '+' enables the controller and '-'
+ disables. If a controller appears more than once on the list,
+ the last one is effective. When multiple enable and disable
+ operations are specified, either all succeed or all fail.
+
+ cgroup.events
+
+ A read-only flat-keyed file which exists on non-root cgroups.
+ The following entries are defined. Unless specified
+ otherwise, a value change in this file generates a file
+ modified event.
+
+ populated
+
+ 1 if the cgroup or its descendants contains any live
+ processes; otherwise, 0.
+
+
+5. Controllers
+
+5-1. CPU
+
+[NOTE: The interface for the cpu controller hasn't been merged yet]
+
+The "cpu" controllers regulates distribution of CPU cycles. This
+controller implements weight and absolute bandwidth limit models for
+normal scheduling policy and absolute bandwidth allocation model for
+realtime scheduling policy.
+
+
+5-1-1. CPU Interface Files
+
+All time durations are in microseconds.
+
+ cpu.stat
+
+ A read-only flat-keyed file which exists on non-root cgroups.
+
+ It reports the following six stats.
+
+ usage_usec
+ user_usec
+ system_usec
+ nr_periods
+ nr_throttled
+ throttled_usec
+
+ cpu.weight
+
+ A read-write single value file which exists on non-root
+ cgroups. The default is "100".
+
+ The weight in the range [1, 10000].
+
+ cpu.max
+
+ A read-write two value file which exists on non-root cgroups.
+ The default is "max 100000".
+
+ The maximum bandwidth limit. It's in the following format.
+
+ $MAX $PERIOD
+
+ which indicates that the group may consume upto $MAX in each
+ $PERIOD duration. "max" for $MAX indicates no limit. If only
+ one number is written, $MAX is updated.
+
+ cpu.rt.max
+
+ [NOTE: The semantics of this file is still under discussion and the
+ interface hasn't been merged yet]
+
+ A read-write two value file which exists on all cgroups.
+ The default is "0 100000".
+
+ The maximum realtime runtime allocation. Over-committing
+ configurations are disallowed and process migrations are
+ rejected if not enough bandwidth is available. It's in the
+ following format.
+
+ $MAX $PERIOD
+
+ which indicates that the group may consume upto $MAX in each
+ $PERIOD duration. If only one number is written, $MAX is
+ updated.
+
+
+5-2. Memory
+
+The "memory" controller regulates distribution of memory. Memory is
+stateful and implements both limit and protection models. Due to the
+intertwining between memory usage and reclaim pressure and the
+stateful nature of memory, the distribution model is relatively
+complex.
+
+While not completely water-tight, all major memory usages by a given
+cgroup are tracked so that the total memory consumption can be
+accounted and controlled to a reasonable extent. Currently, the
+following types of memory usages are tracked.
+
+- Userland memory - page cache and anonymous memory.
+
+- Kernel data structures such as dentries and inodes.
+
+- TCP socket buffers.
+
+The above list may expand in the future for better coverage.
+
+
+5-2-1. Memory Interface Files
+
+All memory amounts are in bytes. If a value which is not aligned to
+PAGE_SIZE is written, the value may be rounded up to the closest
+PAGE_SIZE multiple when read back.
+
+ memory.current
+
+ A read-only single value file which exists on non-root
+ cgroups.
+
+ The total amount of memory currently being used by the cgroup
+ and its descendants.
+
+ memory.low
+
+ A read-write single value file which exists on non-root
+ cgroups. The default is "0".
+
+ Best-effort memory protection. If the memory usages of a
+ cgroup and all its ancestors are below their low boundaries,
+ the cgroup's memory won't be reclaimed unless memory can be
+ reclaimed from unprotected cgroups.
+
+ Putting more memory than generally available under this
+ protection is discouraged.
+
+ memory.high
+
+ A read-write single value file which exists on non-root
+ cgroups. The default is "max".
+
+ Memory usage throttle limit. This is the main mechanism to
+ control memory usage of a cgroup. If a cgroup's usage goes
+ over the high boundary, the processes of the cgroup are
+ throttled and put under heavy reclaim pressure.
+
+ Going over the high limit never invokes the OOM killer and
+ under extreme conditions the limit may be breached.
+
+ memory.max
+
+ A read-write single value file which exists on non-root
+ cgroups. The default is "max".
+
+ Memory usage hard limit. This is the final protection
+ mechanism. If a cgroup's memory usage reaches this limit and
+ can't be reduced, the OOM killer is invoked in the cgroup.
+ Under certain circumstances, the usage may go over the limit
+ temporarily.
+
+ This is the ultimate protection mechanism. As long as the
+ high limit is used and monitored properly, this limit's
+ utility is limited to providing the final safety net.
+
+ memory.events
+
+ A read-only flat-keyed file which exists on non-root cgroups.
+ The following entries are defined. Unless specified
+ otherwise, a value change in this file generates a file
+ modified event.
+
+ low
+
+ The number of times the cgroup is reclaimed due to
+ high memory pressure even though its usage is under
+ the low boundary. This usually indicates that the low
+ boundary is over-committed.
+
+ high
+
+ The number of times processes of the cgroup are
+ throttled and routed to perform direct memory reclaim
+ because the high memory boundary was exceeded. For a
+ cgroup whose memory usage is capped by the high limit
+ rather than global memory pressure, this event's
+ occurrences are expected.
+
+ max
+
+ The number of times the cgroup's memory usage was
+ about to go over the max boundary. If direct reclaim
+ fails to bring it down, the OOM killer is invoked.
+
+ oom
+
+ The number of times the OOM killer has been invoked in
+ the cgroup. This may not exactly match the number of
+ processes killed but should generally be close.
+
+ memory.stat
+
+ A read-only flat-keyed file which exists on non-root cgroups.
+
+ This breaks down the cgroup's memory footprint into different
+ types of memory, type-specific details, and other information
+ on the state and past events of the memory management system.
+
+ All memory amounts are in bytes.
+
+ The entries are ordered to be human readable, and new entries
+ can show up in the middle. Don't rely on items remaining in a
+ fixed position; use the keys to look up specific values!
+
+ anon
+
+ Amount of memory used in anonymous mappings such as
+ brk(), sbrk(), and mmap(MAP_ANONYMOUS)
+
+ file
+
+ Amount of memory used to cache filesystem data,
+ including tmpfs and shared memory.
+
+ file_mapped
+
+ Amount of cached filesystem data mapped with mmap()
+
+ file_dirty
+
+ Amount of cached filesystem data that was modified but
+ not yet written back to disk
+
+ file_writeback
+
+ Amount of cached filesystem data that was modified and
+ is currently being written back to disk
+
+ inactive_anon
+ active_anon
+ inactive_file
+ active_file
+ unevictable
+
+ Amount of memory, swap-backed and filesystem-backed,
+ on the internal memory management lists used by the
+ page reclaim algorithm
+
+ pgfault
+
+ Total number of page faults incurred
+
+ pgmajfault
+
+ Number of major page faults incurred
+
+ memory.swap.current
+
+ A read-only single value file which exists on non-root
+ cgroups.
+
+ The total amount of swap currently being used by the cgroup
+ and its descendants.
+
+ memory.swap.max
+
+ A read-write single value file which exists on non-root
+ cgroups. The default is "max".
+
+ Swap usage hard limit. If a cgroup's swap usage reaches this
+ limit, anonymous meomry of the cgroup will not be swapped out.
+
+
+5-2-2. General Usage
+
+"memory.high" is the main mechanism to control memory usage.
+Over-committing on high limit (sum of high limits > available memory)
+and letting global memory pressure to distribute memory according to
+usage is a viable strategy.
+
+Because breach of the high limit doesn't trigger the OOM killer but
+throttles the offending cgroup, a management agent has ample
+opportunities to monitor and take appropriate actions such as granting
+more memory or terminating the workload.
+
+Determining whether a cgroup has enough memory is not trivial as
+memory usage doesn't indicate whether the workload can benefit from
+more memory. For example, a workload which writes data received from
+network to a file can use all available memory but can also operate as
+performant with a small amount of memory. A measure of memory
+pressure - how much the workload is being impacted due to lack of
+memory - is necessary to determine whether a workload needs more
+memory; unfortunately, memory pressure monitoring mechanism isn't
+implemented yet.
+
+
+5-2-3. Memory Ownership
+
+A memory area is charged to the cgroup which instantiated it and stays
+charged to the cgroup until the area is released. Migrating a process
+to a different cgroup doesn't move the memory usages that it
+instantiated while in the previous cgroup to the new cgroup.
+
+A memory area may be used by processes belonging to different cgroups.
+To which cgroup the area will be charged is in-deterministic; however,
+over time, the memory area is likely to end up in a cgroup which has
+enough memory allowance to avoid high reclaim pressure.
+
+If a cgroup sweeps a considerable amount of memory which is expected
+to be accessed repeatedly by other cgroups, it may make sense to use
+POSIX_FADV_DONTNEED to relinquish the ownership of memory areas
+belonging to the affected files to ensure correct memory ownership.
+
+
+5-3. IO
+
+The "io" controller regulates the distribution of IO resources. This
+controller implements both weight based and absolute bandwidth or IOPS
+limit distribution; however, weight based distribution is available
+only if cfq-iosched is in use and neither scheme is available for
+blk-mq devices.
+
+
+5-3-1. IO Interface Files
+
+ io.stat
+
+ A read-only nested-keyed file which exists on non-root
+ cgroups.
+
+ Lines are keyed by $MAJ:$MIN device numbers and not ordered.
+ The following nested keys are defined.
+
+ rbytes Bytes read
+ wbytes Bytes written
+ rios Number of read IOs
+ wios Number of write IOs
+
+ An example read output follows.
+
+ 8:16 rbytes=1459200 wbytes=314773504 rios=192 wios=353
+ 8:0 rbytes=90430464 wbytes=299008000 rios=8950 wios=1252
+
+ io.weight
+
+ A read-write flat-keyed file which exists on non-root cgroups.
+ The default is "default 100".
+
+ The first line is the default weight applied to devices
+ without specific override. The rest are overrides keyed by
+ $MAJ:$MIN device numbers and not ordered. The weights are in
+ the range [1, 10000] and specifies the relative amount IO time
+ the cgroup can use in relation to its siblings.
+
+ The default weight can be updated by writing either "default
+ $WEIGHT" or simply "$WEIGHT". Overrides can be set by writing
+ "$MAJ:$MIN $WEIGHT" and unset by writing "$MAJ:$MIN default".
+
+ An example read output follows.
+
+ default 100
+ 8:16 200
+ 8:0 50
+
+ io.max
+
+ A read-write nested-keyed file which exists on non-root
+ cgroups.
+
+ BPS and IOPS based IO limit. Lines are keyed by $MAJ:$MIN
+ device numbers and not ordered. The following nested keys are
+ defined.
+
+ rbps Max read bytes per second
+ wbps Max write bytes per second
+ riops Max read IO operations per second
+ wiops Max write IO operations per second
+
+ When writing, any number of nested key-value pairs can be
+ specified in any order. "max" can be specified as the value
+ to remove a specific limit. If the same key is specified
+ multiple times, the outcome is undefined.
+
+ BPS and IOPS are measured in each IO direction and IOs are
+ delayed if limit is reached. Temporary bursts are allowed.
+
+ Setting read limit at 2M BPS and write at 120 IOPS for 8:16.
+
+ echo "8:16 rbps=2097152 wiops=120" > io.max
+
+ Reading returns the following.
+
+ 8:16 rbps=2097152 wbps=max riops=max wiops=120
+
+ Write IOPS limit can be removed by writing the following.
+
+ echo "8:16 wiops=max" > io.max
+
+ Reading now returns the following.
+
+ 8:16 rbps=2097152 wbps=max riops=max wiops=max
+
+
+5-3-2. Writeback
+
+Page cache is dirtied through buffered writes and shared mmaps and
+written asynchronously to the backing filesystem by the writeback
+mechanism. Writeback sits between the memory and IO domains and
+regulates the proportion of dirty memory by balancing dirtying and
+write IOs.
+
+The io controller, in conjunction with the memory controller,
+implements control of page cache writeback IOs. The memory controller
+defines the memory domain that dirty memory ratio is calculated and
+maintained for and the io controller defines the io domain which
+writes out dirty pages for the memory domain. Both system-wide and
+per-cgroup dirty memory states are examined and the more restrictive
+of the two is enforced.
+
+cgroup writeback requires explicit support from the underlying
+filesystem. Currently, cgroup writeback is implemented on ext2, ext4
+and btrfs. On other filesystems, all writeback IOs are attributed to
+the root cgroup.
+
+There are inherent differences in memory and writeback management
+which affects how cgroup ownership is tracked. Memory is tracked per
+page while writeback per inode. For the purpose of writeback, an
+inode is assigned to a cgroup and all IO requests to write dirty pages
+from the inode are attributed to that cgroup.
+
+As cgroup ownership for memory is tracked per page, there can be pages
+which are associated with different cgroups than the one the inode is
+associated with. These are called foreign pages. The writeback
+constantly keeps track of foreign pages and, if a particular foreign
+cgroup becomes the majority over a certain period of time, switches
+the ownership of the inode to that cgroup.
+
+While this model is enough for most use cases where a given inode is
+mostly dirtied by a single cgroup even when the main writing cgroup
+changes over time, use cases where multiple cgroups write to a single
+inode simultaneously are not supported well. In such circumstances, a
+significant portion of IOs are likely to be attributed incorrectly.
+As memory controller assigns page ownership on the first use and
+doesn't update it until the page is released, even if writeback
+strictly follows page ownership, multiple cgroups dirtying overlapping
+areas wouldn't work as expected. It's recommended to avoid such usage
+patterns.
+
+The sysctl knobs which affect writeback behavior are applied to cgroup
+writeback as follows.
+
+ vm.dirty_background_ratio
+ vm.dirty_ratio
+
+ These ratios apply the same to cgroup writeback with the
+ amount of available memory capped by limits imposed by the
+ memory controller and system-wide clean memory.
+
+ vm.dirty_background_bytes
+ vm.dirty_bytes
+
+ For cgroup writeback, this is calculated into ratio against
+ total available memory and applied the same way as
+ vm.dirty[_background]_ratio.
+
+
+P. Information on Kernel Programming
+
+This section contains kernel programming information in the areas
+where interacting with cgroup is necessary. cgroup core and
+controllers are not covered.
+
+
+P-1. Filesystem Support for Writeback
+
+A filesystem can support cgroup writeback by updating
+address_space_operations->writepage[s]() to annotate bio's using the
+following two functions.
+
+ wbc_init_bio(@wbc, @bio)
+
+ Should be called for each bio carrying writeback data and
+ associates the bio with the inode's owner cgroup. Can be
+ called anytime between bio allocation and submission.
+
+ wbc_account_io(@wbc, @page, @bytes)
+
+ Should be called for each data segment being written out.
+ While this function doesn't care exactly when it's called
+ during the writeback session, it's the easiest and most
+ natural to call it as data segments are added to a bio.
+
+With writeback bio's annotated, cgroup support can be enabled per
+super_block by setting SB_I_CGROUPWB in ->s_iflags. This allows for
+selective disabling of cgroup writeback support which is helpful when
+certain filesystem features, e.g. journaled data mode, are
+incompatible.
+
+wbc_init_bio() binds the specified bio to its cgroup. Depending on
+the configuration, the bio may be executed at a lower priority and if
+the writeback session is holding shared resources, e.g. a journal
+entry, may lead to priority inversion. There is no one easy solution
+for the problem. Filesystems can try to work around specific problem
+cases by skipping wbc_init_bio() or using bio_associate_blkcg()
+directly.
+
+
+D. Deprecated v1 Core Features
+
+- Multiple hierarchies including named ones are not supported.
+
+- All mount options and remounting are not supported.
+
+- The "tasks" file is removed and "cgroup.procs" is not sorted.
+
+- "cgroup.clone_children" is removed.
+
+- /proc/cgroups is meaningless for v2. Use "cgroup.controllers" file
+ at the root instead.
+
+
+R. Issues with v1 and Rationales for v2
+
+R-1. Multiple Hierarchies
+
+cgroup v1 allowed an arbitrary number of hierarchies and each
+hierarchy could host any number of controllers. While this seemed to
+provide a high level of flexibility, it wasn't useful in practice.
+
+For example, as there is only one instance of each controller, utility
+type controllers such as freezer which can be useful in all
+hierarchies could only be used in one. The issue is exacerbated by
+the fact that controllers couldn't be moved to another hierarchy once
+hierarchies were populated. Another issue was that all controllers
+bound to a hierarchy were forced to have exactly the same view of the
+hierarchy. It wasn't possible to vary the granularity depending on
+the specific controller.
+
+In practice, these issues heavily limited which controllers could be
+put on the same hierarchy and most configurations resorted to putting
+each controller on its own hierarchy. Only closely related ones, such
+as the cpu and cpuacct controllers, made sense to be put on the same
+hierarchy. This often meant that userland ended up managing multiple
+similar hierarchies repeating the same steps on each hierarchy
+whenever a hierarchy management operation was necessary.
+
+Furthermore, support for multiple hierarchies came at a steep cost.
+It greatly complicated cgroup core implementation but more importantly
+the support for multiple hierarchies restricted how cgroup could be
+used in general and what controllers was able to do.
+
+There was no limit on how many hierarchies there might be, which meant
+that a thread's cgroup membership couldn't be described in finite
+length. The key might contain any number of entries and was unlimited
+in length, which made it highly awkward to manipulate and led to
+addition of controllers which existed only to identify membership,
+which in turn exacerbated the original problem of proliferating number
+of hierarchies.
+
+Also, as a controller couldn't have any expectation regarding the
+topologies of hierarchies other controllers might be on, each
+controller had to assume that all other controllers were attached to
+completely orthogonal hierarchies. This made it impossible, or at
+least very cumbersome, for controllers to cooperate with each other.
+
+In most use cases, putting controllers on hierarchies which are
+completely orthogonal to each other isn't necessary. What usually is
+called for is the ability to have differing levels of granularity
+depending on the specific controller. In other words, hierarchy may
+be collapsed from leaf towards root when viewed from specific
+controllers. For example, a given configuration might not care about
+how memory is distributed beyond a certain level while still wanting
+to control how CPU cycles are distributed.
+
+
+R-2. Thread Granularity
+
+cgroup v1 allowed threads of a process to belong to different cgroups.
+This didn't make sense for some controllers and those controllers
+ended up implementing different ways to ignore such situations but
+much more importantly it blurred the line between API exposed to
+individual applications and system management interface.
+
+Generally, in-process knowledge is available only to the process
+itself; thus, unlike service-level organization of processes,
+categorizing threads of a process requires active participation from
+the application which owns the target process.
+
+cgroup v1 had an ambiguously defined delegation model which got abused
+in combination with thread granularity. cgroups were delegated to
+individual applications so that they can create and manage their own
+sub-hierarchies and control resource distributions along them. This
+effectively raised cgroup to the status of a syscall-like API exposed
+to lay programs.
+
+First of all, cgroup has a fundamentally inadequate interface to be
+exposed this way. For a process to access its own knobs, it has to
+extract the path on the target hierarchy from /proc/self/cgroup,
+construct the path by appending the name of the knob to the path, open
+and then read and/or write to it. This is not only extremely clunky
+and unusual but also inherently racy. There is no conventional way to
+define transaction across the required steps and nothing can guarantee
+that the process would actually be operating on its own sub-hierarchy.
+
+cgroup controllers implemented a number of knobs which would never be
+accepted as public APIs because they were just adding control knobs to
+system-management pseudo filesystem. cgroup ended up with interface
+knobs which were not properly abstracted or refined and directly
+revealed kernel internal details. These knobs got exposed to
+individual applications through the ill-defined delegation mechanism
+effectively abusing cgroup as a shortcut to implementing public APIs
+without going through the required scrutiny.
+
+This was painful for both userland and kernel. Userland ended up with
+misbehaving and poorly abstracted interfaces and kernel exposing and
+locked into constructs inadvertently.
+
+
+R-3. Competition Between Inner Nodes and Threads
+
+cgroup v1 allowed threads to be in any cgroups which created an
+interesting problem where threads belonging to a parent cgroup and its
+children cgroups competed for resources. This was nasty as two
+different types of entities competed and there was no obvious way to
+settle it. Different controllers did different things.
+
+The cpu controller considered threads and cgroups as equivalents and
+mapped nice levels to cgroup weights. This worked for some cases but
+fell flat when children wanted to be allocated specific ratios of CPU
+cycles and the number of internal threads fluctuated - the ratios
+constantly changed as the number of competing entities fluctuated.
+There also were other issues. The mapping from nice level to weight
+wasn't obvious or universal, and there were various other knobs which
+simply weren't available for threads.
+
+The io controller implicitly created a hidden leaf node for each
+cgroup to host the threads. The hidden leaf had its own copies of all
+the knobs with "leaf_" prefixed. While this allowed equivalent
+control over internal threads, it was with serious drawbacks. It
+always added an extra layer of nesting which wouldn't be necessary
+otherwise, made the interface messy and significantly complicated the
+implementation.
+
+The memory controller didn't have a way to control what happened
+between internal tasks and child cgroups and the behavior was not
+clearly defined. There were attempts to add ad-hoc behaviors and
+knobs to tailor the behavior to specific workloads which would have
+led to problems extremely difficult to resolve in the long term.
+
+Multiple controllers struggled with internal tasks and came up with
+different ways to deal with it; unfortunately, all the approaches were
+severely flawed and, furthermore, the widely different behaviors
+made cgroup as a whole highly inconsistent.
+
+This clearly is a problem which needs to be addressed from cgroup core
+in a uniform way.
+
+
+R-4. Other Interface Issues
+
+cgroup v1 grew without oversight and developed a large number of
+idiosyncrasies and inconsistencies. One issue on the cgroup core side
+was how an empty cgroup was notified - a userland helper binary was
+forked and executed for each event. The event delivery wasn't
+recursive or delegatable. The limitations of the mechanism also led
+to in-kernel event delivery filtering mechanism further complicating
+the interface.
+
+Controller interfaces were problematic too. An extreme example is
+controllers completely ignoring hierarchical organization and treating
+all cgroups as if they were all located directly under the root
+cgroup. Some controllers exposed a large amount of inconsistent
+implementation details to userland.
+
+There also was no consistency across controllers. When a new cgroup
+was created, some controllers defaulted to not imposing extra
+restrictions while others disallowed any resource usage until
+explicitly configured. Configuration knobs for the same type of
+control used widely differing naming schemes and formats. Statistics
+and information knobs were named arbitrarily and used different
+formats and units even in the same controller.
+
+cgroup v2 establishes common conventions where appropriate and updates
+controllers so that they expose minimal and consistent interfaces.
+
+
+R-5. Controller Issues and Remedies
+
+R-5-1. Memory
+
+The original lower boundary, the soft limit, is defined as a limit
+that is per default unset. As a result, the set of cgroups that
+global reclaim prefers is opt-in, rather than opt-out. The costs for
+optimizing these mostly negative lookups are so high that the
+implementation, despite its enormous size, does not even provide the
+basic desirable behavior. First off, the soft limit has no
+hierarchical meaning. All configured groups are organized in a global
+rbtree and treated like equal peers, regardless where they are located
+in the hierarchy. This makes subtree delegation impossible. Second,
+the soft limit reclaim pass is so aggressive that it not just
+introduces high allocation latencies into the system, but also impacts
+system performance due to overreclaim, to the point where the feature
+becomes self-defeating.
+
+The memory.low boundary on the other hand is a top-down allocated
+reserve. A cgroup enjoys reclaim protection when it and all its
+ancestors are below their low boundaries, which makes delegation of
+subtrees possible. Secondly, new cgroups have no reserve per default
+and in the common case most cgroups are eligible for the preferred
+reclaim pass. This allows the new low boundary to be efficiently
+implemented with just a minor addition to the generic reclaim code,
+without the need for out-of-band data structures and reclaim passes.
+Because the generic reclaim code considers all cgroups except for the
+ones running low in the preferred first reclaim pass, overreclaim of
+individual groups is eliminated as well, resulting in much better
+overall workload performance.
+
+The original high boundary, the hard limit, is defined as a strict
+limit that can not budge, even if the OOM killer has to be called.
+But this generally goes against the goal of making the most out of the
+available memory. The memory consumption of workloads varies during
+runtime, and that requires users to overcommit. But doing that with a
+strict upper limit requires either a fairly accurate prediction of the
+working set size or adding slack to the limit. Since working set size
+estimation is hard and error prone, and getting it wrong results in
+OOM kills, most users tend to err on the side of a looser limit and
+end up wasting precious resources.
+
+The memory.high boundary on the other hand can be set much more
+conservatively. When hit, it throttles allocations by forcing them
+into direct reclaim to work off the excess, but it never invokes the
+OOM killer. As a result, a high boundary that is chosen too
+aggressively will not terminate the processes, but instead it will
+lead to gradual performance degradation. The user can monitor this
+and make corrections until the minimal memory footprint that still
+gives acceptable performance is found.
+
+In extreme cases, with many concurrent allocations and a complete
+breakdown of reclaim progress within the group, the high boundary can
+be exceeded. But even then it's mostly better to satisfy the
+allocation from the slack available in other groups or the rest of the
+system than killing the group. Otherwise, memory.max is there to
+limit this type of spillover and ultimately contain buggy or even
+malicious applications.
+
+The combined memory+swap accounting and limiting is replaced by real
+control over swap space.
+
+The main argument for a combined memory+swap facility in the original
+cgroup design was that global or parental pressure would always be
+able to swap all anonymous memory of a child group, regardless of the
+child's own (possibly untrusted) configuration. However, untrusted
+groups can sabotage swapping by other means - such as referencing its
+anonymous memory in a tight loop - and an admin can not assume full
+swappability when overcommitting untrusted jobs.
+
+For trusted jobs, on the other hand, a combined counter is not an
+intuitive userspace interface, and it flies in the face of the idea
+that cgroup controllers should account and limit specific physical
+resources. Swap space is a resource like all others in the system,
+and that's why unified hierarchy allows distributing it separately.

-
-
-1. Background
-
-cgroup allows an arbitrary number of hierarchies and each hierarchy
-can host any number of controllers. While this seems to provide a
-high level of flexibility, it isn't quite useful in practice.
-
-For example, as there is only one instance of each controller, utility
-type controllers such as freezer which can be useful in all
-hierarchies can only be used in one. The issue is exacerbated by the
-fact that controllers can't be moved around once hierarchies are
-populated. Another issue is that all controllers bound to a hierarchy
-are forced to have exactly the same view of the hierarchy. It isn't
-possible to vary the granularity depending on the specific controller.
-
-In practice, these issues heavily limit which controllers can be put
-on the same hierarchy and most configurations resort to putting each
-controller on its own hierarchy. Only closely related ones, such as
-the cpu and cpuacct controllers, make sense to put on the same
-hierarchy. This often means that userland ends up managing multiple
-similar hierarchies repeating the same steps on each hierarchy
-whenever a hierarchy management operation is necessary.
-
-Unfortunately, support for multiple hierarchies comes at a steep cost.
-Internal implementation in cgroup core proper is dazzlingly
-complicated but more importantly the support for multiple hierarchies
-restricts how cgroup is used in general and what controllers can do.
-
-There's no limit on how many hierarchies there may be, which means
-that a task's cgroup membership can't be described in finite length.
-The key may contain any varying number of entries and is unlimited in
-length, which makes it highly awkward to handle and leads to addition
-of controllers which exist only to identify membership, which in turn
-exacerbates the original problem.
-
-Also, as a controller can't have any expectation regarding what shape
-of hierarchies other controllers would be on, each controller has to
-assume that all other controllers are operating on completely
-orthogonal hierarchies. This makes it impossible, or at least very
-cumbersome, for controllers to cooperate with each other.
-
-In most use cases, putting controllers on hierarchies which are
-completely orthogonal to each other isn't necessary. What usually is
-called for is the ability to have differing levels of granularity
-depending on the specific controller. In other words, hierarchy may
-be collapsed from leaf towards root when viewed from specific
-controllers. For example, a given configuration might not care about
-how memory is distributed beyond a certain level while still wanting
-to control how CPU cycles are distributed.
-
-Unified hierarchy is the next version of cgroup interface. It aims to
-address the aforementioned issues by having more structure while
-retaining enough flexibility for most use cases. Various other
-general and controller-specific interface issues are also addressed in
-the process.
-
-
-2. Basic Operation
-
-2-1. Mounting
-
-Currently, unified hierarchy can be mounted with the following mount
-command. Note that this is still under development and scheduled to
-change soon.
-
- mount -t cgroup -o __DEVEL__sane_behavior cgroup $MOUNT_POINT
-
-All controllers which support the unified hierarchy and are not bound
-to other hierarchies are automatically bound to unified hierarchy and
-show up at the root of it. Controllers which are enabled only in the
-root of unified hierarchy can be bound to other hierarchies. This
-allows mixing unified hierarchy with the traditional multiple
-hierarchies in a fully backward compatible way.
-
-A controller can be moved across hierarchies only after the controller
-is no longer referenced in its current hierarchy. Because per-cgroup
-controller states are destroyed asynchronously and controllers may
-have lingering references, a controller may not show up immediately on
-the unified hierarchy after the final umount of the previous
-hierarchy. Similarly, a controller should be fully disabled to be
-moved out of the unified hierarchy and it may take some time for the
-disabled controller to become available for other hierarchies;
-furthermore, due to dependencies among controllers, other controllers
-may need to be disabled too.
-
-While useful for development and manual configurations, dynamically
-moving controllers between the unified and other hierarchies is
-strongly discouraged for production use. It is recommended to decide
-the hierarchies and controller associations before starting using the
-controllers.
-
-
-2-2. cgroup.subtree_control
-
-All cgroups on unified hierarchy have a "cgroup.subtree_control" file
-which governs which controllers are enabled on the children of the
-cgroup. Let's assume a hierarchy like the following.
-
- root - A - B - C
- \ D
-
-root's "cgroup.subtree_control" file determines which controllers are
-enabled on A. A's on B. B's on C and D. This coincides with the
-fact that controllers on the immediate sub-level are used to
-distribute the resources of the parent. In fact, it's natural to
-assume that resource control knobs of a child belong to its parent.
-Enabling a controller in a "cgroup.subtree_control" file declares that
-distribution of the respective resources of the cgroup will be
-controlled. Note that this means that controller enable states are
-shared among siblings.
-
-When read, the file contains a space-separated list of currently
-enabled controllers. A write to the file should contain a
-space-separated list of controllers with '+' or '-' prefixed (without
-the quotes). Controllers prefixed with '+' are enabled and '-'
-disabled. If a controller is listed multiple times, the last entry
-wins. The specific operations are executed atomically - either all
-succeed or fail.
-
-
-2-3. cgroup.controllers
-
-Read-only "cgroup.controllers" file contains a space-separated list of
-controllers which can be enabled in the cgroup's
-"cgroup.subtree_control" file.
-
-In the root cgroup, this lists controllers which are not bound to
-other hierarchies and the content changes as controllers are bound to
-and unbound from other hierarchies.
-
-In non-root cgroups, the content of this file equals that of the
-parent's "cgroup.subtree_control" file as only controllers enabled
-from the parent can be used in its children.
-
-
-3. Structural Constraints
-
-3-1. Top-down
-
-As it doesn't make sense to nest control of an uncontrolled resource,
-all non-root "cgroup.subtree_control" files can only contain
-controllers which are enabled in the parent's "cgroup.subtree_control"
-file. A controller can be enabled only if the parent has the
-controller enabled and a controller can't be disabled if one or more
-children have it enabled.
-
-
-3-2. No internal tasks
-
-One long-standing issue that cgroup faces is the competition between
-tasks belonging to the parent cgroup and its children cgroups. This
-is inherently nasty as two different types of entities compete and
-there is no agreed-upon obvious way to handle it. Different
-controllers are doing different things.
-
-The cpu controller considers tasks and cgroups as equivalents and maps
-nice levels to cgroup weights. This works for some cases but falls
-flat when children should be allocated specific ratios of CPU cycles
-and the number of internal tasks fluctuates - the ratios constantly
-change as the number of competing entities fluctuates. There also are
-other issues. The mapping from nice level to weight isn't obvious or
-universal, and there are various other knobs which simply aren't
-available for tasks.
-
-The io controller implicitly creates a hidden leaf node for each
-cgroup to host the tasks. The hidden leaf has its own copies of all
-the knobs with "leaf_" prefixed. While this allows equivalent control
-over internal tasks, it's with serious drawbacks. It always adds an
-extra layer of nesting which may not be necessary, makes the interface
-messy and significantly complicates the implementation.
-
-The memory controller currently doesn't have a way to control what
-happens between internal tasks and child cgroups and the behavior is
-not clearly defined. There have been attempts to add ad-hoc behaviors
-and knobs to tailor the behavior to specific workloads. Continuing
-this direction will lead to problems which will be extremely difficult
-to resolve in the long term.
-
-Multiple controllers struggle with internal tasks and came up with
-different ways to deal with it; unfortunately, all the approaches in
-use now are severely flawed and, furthermore, the widely different
-behaviors make cgroup as whole highly inconsistent.
-
-It is clear that this is something which needs to be addressed from
-cgroup core proper in a uniform way so that controllers don't need to
-worry about it and cgroup as a whole shows a consistent and logical
-behavior. To achieve that, unified hierarchy enforces the following
-structural constraint:
-
- Except for the root, only cgroups which don't contain any task may
- have controllers enabled in their "cgroup.subtree_control" files.
-
-Combined with other properties, this guarantees that, when a
-controller is looking at the part of the hierarchy which has it
-enabled, tasks are always only on the leaves. This rules out
-situations where child cgroups compete against internal tasks of the
-parent.
-
-There are two things to note. Firstly, the root cgroup is exempt from
-the restriction. Root contains tasks and anonymous resource
-consumption which can't be associated with any other cgroup and
-requires special treatment from most controllers. How resource
-consumption in the root cgroup is governed is up to each controller.
-
-Secondly, the restriction doesn't take effect if there is no enabled
-controller in the cgroup's "cgroup.subtree_control" file. This is
-important as otherwise it wouldn't be possible to create children of a
-populated cgroup. To control resource distribution of a cgroup, the
-cgroup must create children and transfer all its tasks to the children
-before enabling controllers in its "cgroup.subtree_control" file.
-
-
-4. Delegation
-
-4-1. Model of delegation
-
-A cgroup can be delegated to a less privileged user by granting write
-access of the directory and its "cgroup.procs" file to the user. Note
-that the resource control knobs in a given directory concern the
-resources of the parent and thus must not be delegated along with the
-directory.
-
-Once delegated, the user can build sub-hierarchy under the directory,
-organize processes as it sees fit and further distribute the resources
-it got from the parent. The limits and other settings of all resource
-controllers are hierarchical and regardless of what happens in the
-delegated sub-hierarchy, nothing can escape the resource restrictions
-imposed by the parent.
-
-Currently, cgroup doesn't impose any restrictions on the number of
-cgroups in or nesting depth of a delegated sub-hierarchy; however,
-this may in the future be limited explicitly.
-
-
-4-2. Common ancestor rule
-
-On the unified hierarchy, to write to a "cgroup.procs" file, in
-addition to the usual write permission to the file and uid match, the
-writer must also have write access to the "cgroup.procs" file of the
-common ancestor of the source and destination cgroups. This prevents
-delegatees from smuggling processes across disjoint sub-hierarchies.
-
-Let's say cgroups C0 and C1 have been delegated to user U0 who created
-C00, C01 under C0 and C10 under C1 as follows.
-
- ~~~~~~~~~~~~~ - C0 - C00
- ~ cgroup ~ \ C01
- ~ hierarchy ~
- ~~~~~~~~~~~~~ - C1 - C10
-
-C0 and C1 are separate entities in terms of resource distribution
-regardless of their relative positions in the hierarchy. The
-resources the processes under C0 are entitled to are controlled by
-C0's ancestors and may be completely different from C1. It's clear
-that the intention of delegating C0 to U0 is allowing U0 to organize
-the processes under C0 and further control the distribution of C0's
-resources.
-
-On traditional hierarchies, if a task has write access to "tasks" or
-"cgroup.procs" file of a cgroup and its uid agrees with the target, it
-can move the target to the cgroup. In the above example, U0 will not
-only be able to move processes in each sub-hierarchy but also across
-the two sub-hierarchies, effectively allowing it to violate the
-organizational and resource restrictions implied by the hierarchical
-structure above C0 and C1.
-
-On the unified hierarchy, let's say U0 wants to write the pid of a
-process which has a matching uid and is currently in C10 into
-"C00/cgroup.procs". U0 obviously has write access to the file and
-migration permission on the process; however, the common ancestor of
-the source cgroup C10 and the destination cgroup C00 is above the
-points of delegation and U0 would not have write access to its
-"cgroup.procs" and thus be denied with -EACCES.
-
-
-5. Other Changes
-
-5-1. [Un]populated Notification
-
-cgroup users often need a way to determine when a cgroup's
-subhierarchy becomes empty so that it can be cleaned up. cgroup
-currently provides release_agent for it; unfortunately, this mechanism
-is riddled with issues.
-
-- It delivers events by forking and execing a userland binary
- specified as the release_agent. This is a long deprecated method of
- notification delivery. It's extremely heavy, slow and cumbersome to
- integrate with larger infrastructure.
-
-- There is single monitoring point at the root. There's no way to
- delegate management of a subtree.
-
-- The event isn't recursive. It triggers when a cgroup doesn't have
- any tasks or child cgroups. Events for internal nodes trigger only
- after all children are removed. This again makes it impossible to
- delegate management of a subtree.
-
-- Events are filtered from the kernel side. A "notify_on_release"
- file is used to subscribe to or suppress release events. This is
- unnecessarily complicated and probably done this way because event
- delivery itself was expensive.
-
-Unified hierarchy implements "populated" field in "cgroup.events"
-interface file which can be used to monitor whether the cgroup's
-subhierarchy has tasks in it or not. Its value is 0 if there is no
-task in the cgroup and its descendants; otherwise, 1. poll and
-[id]notify events are triggered when the value changes.
-
-This is significantly lighter and simpler and trivially allows
-delegating management of subhierarchy - subhierarchy monitoring can
-block further propagation simply by putting itself or another process
-in the subhierarchy and monitor events that it's interested in from
-there without interfering with monitoring higher in the tree.
-
-In unified hierarchy, the release_agent mechanism is no longer
-supported and the interface files "release_agent" and
-"notify_on_release" do not exist.
-
-
-5-2. Other Core Changes
-
-- None of the mount options is allowed.
-
-- remount is disallowed.
-
-- rename(2) is disallowed.
-
-- The "tasks" file is removed. Everything should at process
- granularity. Use the "cgroup.procs" file instead.
-
-- The "cgroup.procs" file is not sorted. pids will be unique unless
- they got recycled in-between reads.
-
-- The "cgroup.clone_children" file is removed.
-
-- /proc/PID/cgroup keeps reporting the cgroup that a zombie belonged
- to before exiting. If the cgroup is removed before the zombie is
- reaped, " (deleted)" is appeneded to the path.
-
-
-5-3. Controller File Conventions
-
-5-3-1. Format
-
-In general, all controller files should be in one of the following
-formats whenever possible.
-
-- Values only files
-
- VAL0 VAL1...\n
-
-- Flat keyed files
-
- KEY0 VAL0\n
- KEY1 VAL1\n
- ...
-
-- Nested keyed files
-
- KEY0 SUB_KEY0=VAL00 SUB_KEY1=VAL01...
- KEY1 SUB_KEY0=VAL10 SUB_KEY1=VAL11...
- ...
-
-For a writeable file, the format for writing should generally match
-reading; however, controllers may allow omitting later fields or
-implement restricted shortcuts for most common use cases.
-
-For both flat and nested keyed files, only the values for a single key
-can be written at a time. For nested keyed files, the sub key pairs
-may be specified in any order and not all pairs have to be specified.
-
-
-5-3-2. Control Knobs
-
-- Settings for a single feature should generally be implemented in a
- single file.
-
-- In general, the root cgroup should be exempt from resource control
- and thus shouldn't have resource control knobs.
-
-- If a controller implements ratio based resource distribution, the
- control knob should be named "weight" and have the range [1, 10000]
- and 100 should be the default value. The values are chosen to allow
- enough and symmetric bias in both directions while keeping it
- intuitive (the default is 100%).
-
-- If a controller implements an absolute resource guarantee and/or
- limit, the control knobs should be named "min" and "max"
- respectively. If a controller implements best effort resource
- gurantee and/or limit, the control knobs should be named "low" and
- "high" respectively.
-
- In the above four control files, the special token "max" should be
- used to represent upward infinity for both reading and writing.
-
-- If a setting has configurable default value and specific overrides,
- the default settings should be keyed with "default" and appear as
- the first entry in the file. Specific entries can use "default" as
- its value to indicate inheritance of the default value.
-
-- For events which are not very high frequency, an interface file
- "events" should be created which lists event key value pairs.
- Whenever a notifiable event happens, file modified event should be
- generated on the file.
-
-
-5-4. Per-Controller Changes
-
-5-4-1. io
-
-- blkio is renamed to io. The interface is overhauled anyway. The
- new name is more in line with the other two major controllers, cpu
- and memory, and better suited given that it may be used for cgroup
- writeback without involving block layer.
-
-- Everything including stat is always hierarchical making separate
- recursive stat files pointless and, as no internal node can have
- tasks, leaf weights are meaningless. The operation model is
- simplified and the interface is overhauled accordingly.
-
- io.stat
-
- The stat file. The reported stats are from the point where
- bio's are issued to request_queue. The stats are counted
- independent of which policies are enabled. Each line in the
- file follows the following format. More fields may later be
- added at the end.
-
- $MAJ:$MIN rbytes=$RBYTES wbytes=$WBYTES rios=$RIOS wrios=$WIOS
-
- io.weight
-
- The weight setting, currently only available and effective if
- cfq-iosched is in use for the target device. The weight is
- between 1 and 10000 and defaults to 100. The first line
- always contains the default weight in the following format to
- use when per-device setting is missing.
-
- default $WEIGHT
-
- Subsequent lines list per-device weights of the following
- format.
-
- $MAJ:$MIN $WEIGHT
-
- Writing "$WEIGHT" or "default $WEIGHT" changes the default
- setting. Writing "$MAJ:$MIN $WEIGHT" sets per-device weight
- while "$MAJ:$MIN default" clears it.
-
- This file is available only on non-root cgroups.
-
- io.max
-
- The maximum bandwidth and/or iops setting, only available if
- blk-throttle is enabled. The file is of the following format.
-
- $MAJ:$MIN rbps=$RBPS wbps=$WBPS riops=$RIOPS wiops=$WIOPS
-
- ${R|W}BPS are read/write bytes per second and ${R|W}IOPS are
- read/write IOs per second. "max" indicates no limit. Writing
- to the file follows the same format but the individual
- settings may be omitted or specified in any order.
-
- This file is available only on non-root cgroups.
-
-
-5-4-2. cpuset
-
-- Tasks are kept in empty cpusets after hotplug and take on the masks
- of the nearest non-empty ancestor, instead of being moved to it.
-
-- A task can be moved into an empty cpuset, and again it takes on the
- masks of the nearest non-empty ancestor.
-
-
-5-4-3. memory
-
-- use_hierarchy is on by default and the cgroup file for the flag is
- not created.
-
-- The original lower boundary, the soft limit, is defined as a limit
- that is per default unset. As a result, the set of cgroups that
- global reclaim prefers is opt-in, rather than opt-out. The costs
- for optimizing these mostly negative lookups are so high that the
- implementation, despite its enormous size, does not even provide the
- basic desirable behavior. First off, the soft limit has no
- hierarchical meaning. All configured groups are organized in a
- global rbtree and treated like equal peers, regardless where they
- are located in the hierarchy. This makes subtree delegation
- impossible. Second, the soft limit reclaim pass is so aggressive
- that it not just introduces high allocation latencies into the
- system, but also impacts system performance due to overreclaim, to
- the point where the feature becomes self-defeating.
-
- The memory.low boundary on the other hand is a top-down allocated
- reserve. A cgroup enjoys reclaim protection when it and all its
- ancestors are below their low boundaries, which makes delegation of
- subtrees possible. Secondly, new cgroups have no reserve per
- default and in the common case most cgroups are eligible for the
- preferred reclaim pass. This allows the new low boundary to be
- efficiently implemented with just a minor addition to the generic
- reclaim code, without the need for out-of-band data structures and
- reclaim passes. Because the generic reclaim code considers all
- cgroups except for the ones running low in the preferred first
- reclaim pass, overreclaim of individual groups is eliminated as
- well, resulting in much better overall workload performance.
-
-- The original high boundary, the hard limit, is defined as a strict
- limit that can not budge, even if the OOM killer has to be called.
- But this generally goes against the goal of making the most out of
- the available memory. The memory consumption of workloads varies
- during runtime, and that requires users to overcommit. But doing
- that with a strict upper limit requires either a fairly accurate
- prediction of the working set size or adding slack to the limit.
- Since working set size estimation is hard and error prone, and
- getting it wrong results in OOM kills, most users tend to err on the
- side of a looser limit and end up wasting precious resources.
-
- The memory.high boundary on the other hand can be set much more
- conservatively. When hit, it throttles allocations by forcing them
- into direct reclaim to work off the excess, but it never invokes the
- OOM killer. As a result, a high boundary that is chosen too
- aggressively will not terminate the processes, but instead it will
- lead to gradual performance degradation. The user can monitor this
- and make corrections until the minimal memory footprint that still
- gives acceptable performance is found.
-
- In extreme cases, with many concurrent allocations and a complete
- breakdown of reclaim progress within the group, the high boundary
- can be exceeded. But even then it's mostly better to satisfy the
- allocation from the slack available in other groups or the rest of
- the system than killing the group. Otherwise, memory.max is there
- to limit this type of spillover and ultimately contain buggy or even
- malicious applications.
-
-- The original control file names are unwieldy and inconsistent in
- many different ways. For example, the upper boundary hit count is
- exported in the memory.failcnt file, but an OOM event count has to
- be manually counted by listening to memory.oom_control events, and
- lower boundary / soft limit events have to be counted by first
- setting a threshold for that value and then counting those events.
- Also, usage and limit files encode their units in the filename.
- That makes the filenames very long, even though this is not
- information that a user needs to be reminded of every time they type
- out those names.
-
- To address these naming issues, as well as to signal clearly that
- the new interface carries a new configuration model, the naming
- conventions in it necessarily differ from the old interface.
-
-- The original limit files indicate the state of an unset limit with a
- Very High Number, and a configured limit can be unset by echoing -1
- into those files. But that very high number is implementation and
- architecture dependent and not very descriptive. And while -1 can
- be understood as an underflow into the highest possible value, -2 or
- -10M etc. do not work, so it's not consistent.
-
- memory.low, memory.high, and memory.max will use the string "max" to
- indicate and set the highest possible value.
-
-6. Planned Changes
-
-6-1. CAP for resource control
-
-Unified hierarchy will require one of the capabilities(7), which is
-yet to be decided, for all resource control related knobs. Process
-organization operations - creation of sub-cgroups and migration of
-processes in sub-hierarchies may be delegated by changing the
-ownership and/or permissions on the cgroup directory and
-"cgroup.procs" interface file; however, all operations which affect
-resource control - writes to a "cgroup.subtree_control" file or any
-controller-specific knobs - will require an explicit CAP privilege.
-
-This, in part, is to prevent the cgroup interface from being
-inadvertently promoted to programmable API used by non-privileged
-binaries. cgroup exposes various aspects of the system in ways which
-aren't properly abstracted for direct consumption by regular programs.
-This is an administration interface much closer to sysctl knobs than
-system calls. Even the basic access model, being filesystem path
-based, isn't suitable for direct consumption. There's no way to
-access "my cgroup" in a race-free way or make multiple operations
-atomic against migration to another cgroup.
-
-Another aspect is that, for better or for worse, the cgroup interface
-goes through far less scrutiny than regular interfaces for
-unprivileged userland. The upside is that cgroup is able to expose
-useful features which may not be suitable for general consumption in a
-reasonable time frame. It provides a relatively short path between
-internal details and userland-visible interface. Of course, this
-shortcut comes with high risk. We go through what we go through for
-general kernel APIs for good reasons. It may end up leaking internal
-details in a way which can exert significant pain by locking the
-kernel into a contract that can't be maintained in a reasonable
-manner.
-
-Also, due to the specific nature, cgroup and its controllers don't
-tend to attract attention from a wide scope of developers. cgroup's
-short history is already fraught with severely mis-designed
-interfaces, unnecessary commitments to and exposing of internal
-details, broken and dangerous implementations of various features.
-
-Keeping cgroup as an administration interface is both advantageous for
-its role and imperative given its nature. Some of the cgroup features
-may make sense for unprivileged access. If deemed justified, those
-must be further abstracted and implemented as a different interface,
-be it a system call or process-private filesystem, and survive through
-the scrutiny that any interface for general consumption is required to
-go through.
-
-Requiring CAP is not a complete solution but should serve as a
-significant deterrent against spraying cgroup usages in non-privileged
-programs.

-Intel P-state driver
+Intel P-State driver
--------------------
-This driver provides an interface to control the P state selection for
-SandyBridge+ Intel processors. The driver can operate two different
-modes based on the processor model, legacy mode and Hardware P state (HWP)
-mode.
-
-In legacy mode, the Intel P-state implements two internal governors,
-performance and powersave, that differ from the general cpufreq governors of
-the same name (the general cpufreq governors implement target(), whereas the
-internal Intel P-state governors implement setpolicy()). The internal
-performance governor sets the max_perf_pct and min_perf_pct to 100; that is,
-the governor selects the highest available P state to maximize the performance
-of the core. The internal powersave governor selects the appropriate P state
-based on the current load on the CPU.
-
-In HWP mode P state selection is implemented in the processor
-itself. The driver provides the interfaces between the cpufreq core and
-the processor to control P state selection based on user preferences
-and reporting frequency to the cpufreq core. In this mode the
-internal Intel P-state governor code is disabled.
-
-In addition to the interfaces provided by the cpufreq core for
-controlling frequency the driver provides sysfs files for
-controlling P state selection. These files have been added to
-/sys/devices/system/cpu/intel_pstate/
-
- max_perf_pct: limits the maximum P state that will be requested by
- the driver stated as a percentage of the available performance. The
- available (P states) performance may be reduced by the no_turbo
+This driver provides an interface to control the P-State selection for the
+SandyBridge+ Intel processors.
+
+The following document explains P-States:
+http://events.linuxfoundation.org/sites/events/files/slides/LinuxConEurope_2015.pdf
+As stated in the document, P-State doesn’t exactly mean a frequency. However, for
+the sake of the relationship with cpufreq, P-State and frequency are used
+interchangeably.
+
+Understanding the cpufreq core governors and policies are important before
+discussing more details about the Intel P-State driver. Based on what callbacks
+a cpufreq driver provides to the cpufreq core, it can support two types of
+drivers:
+- with target_index() callback: In this mode, the drivers using cpufreq core
+simply provide the minimum and maximum frequency limits and an additional
+interface target_index() to set the current frequency. The cpufreq subsystem
+has a number of scaling governors ("performance", "powersave", "ondemand",
+etc.). Depending on which governor is in use, cpufreq core will call for
+transitions to a specific frequency using target_index() callback.
+- setpolicy() callback: In this mode, drivers do not provide target_index()
+callback, so cpufreq core can't request a transition to a specific frequency.
+The driver provides minimum and maximum frequency limits and callbacks to set a
+policy. The policy in cpufreq sysfs is referred to as the "scaling governor".
+The cpufreq core can request the driver to operate in any of the two policies:
+"performance: and "powersave". The driver decides which frequency to use based
+on the above policy selection considering minimum and maximum frequency limits.
+
+The Intel P-State driver falls under the latter category, which implements the
+setpolicy() callback. This driver decides what P-State to use based on the
+requested policy from the cpufreq core. If the processor is capable of
+selecting its next P-State internally, then the driver will offload this
+responsibility to the processor (aka HWP: Hardware P-States). If not, the
+driver implements algorithms to select the next P-State.
+
+Since these policies are implemented in the driver, they are not same as the
+cpufreq scaling governors implementation, even if they have the same name in
+the cpufreq sysfs (scaling_governors). For example the "performance" policy is
+similar to cpufreq’s "performance" governor, but "powersave" is completely
+different than the cpufreq "powersave" governor. The strategy here is similar
+to cpufreq "ondemand", where the requested P-State is related to the system load.
+
+Sysfs Interface
+
+In addition to the frequency-controlling interfaces provided by the cpufreq
+core, the driver provides its own sysfs files to control the P-State selection.
+These files have been added to /sys/devices/system/cpu/intel_pstate/.
+Any changes made to these files are applicable to all CPUs (even in a
+multi-package system).
+
+ max_perf_pct: Limits the maximum P-State that will be requested by
+ the driver. It states it as a percentage of the available performance. The
+ available (P-State) performance may be reduced by the no_turbo
setting described below.
- min_perf_pct: limits the minimum P state that will be requested by
- the driver stated as a percentage of the max (non-turbo)
+ min_perf_pct: Limits the minimum P-State that will be requested by
+ the driver. It states it as a percentage of the max (non-turbo)
performance level.
- no_turbo: limits the driver to selecting P states below the turbo
+ no_turbo: Limits the driver to selecting P-State below the turbo
frequency range.
- turbo_pct: displays the percentage of the total performance that
- is supported by hardware that is in the turbo range. This number
+ turbo_pct: Displays the percentage of the total performance that
+ is supported by hardware that is in the turbo range. This number
is independent of whether turbo has been disabled or not.
- num_pstates: displays the number of pstates that are supported
- by hardware. This number is independent of whether turbo has
+ num_pstates: Displays the number of P-States that are supported
+ by hardware. This number is independent of whether turbo has
been disabled or not.
+For example, if a system has these parameters:
+ Max 1 core turbo ratio: 0x21 (Max 1 core ratio is the maximum P-State)
+ Max non turbo ratio: 0x17
+ Minimum ratio : 0x08 (Here the ratio is called max efficiency ratio)
+
+Sysfs will show :
+ max_perf_pct:100, which corresponds to 1 core ratio
+ min_perf_pct:24, max_efficiency_ratio / max 1 Core ratio
+ no_turbo:0, turbo is not disabled
+ num_pstates:26 = (max 1 Core ratio - Max Efficiency Ratio + 1)
+ turbo_pct:39 = (max 1 core ratio - max non turbo ratio) / num_pstates
+
+Refer to "Intel® 64 and IA-32 Architectures Software Developer’s Manual
+Volume 3: System Programming Guide" to understand ratios.
+
+cpufreq sysfs for Intel P-State
+
+Since this driver registers with cpufreq, cpufreq sysfs is also presented.
+There are some important differences, which need to be considered.
+
+scaling_cur_freq: This displays the real frequency which was used during
+the last sample period instead of what is requested. Some other cpufreq driver,
+like acpi-cpufreq, displays what is requested (Some changes are on the
+way to fix this for acpi-cpufreq driver). The same is true for frequencies
+displayed at /proc/cpuinfo.
+
+scaling_governor: This displays current active policy. Since each CPU has a
+cpufreq sysfs, it is possible to set a scaling governor to each CPU. But this
+is not possible with Intel P-States, as there is one common policy for all
+CPUs. Here, the last requested policy will be applicable to all CPUs. It is
+suggested that one use the cpupower utility to change policy to all CPUs at the
+same time.
+
+scaling_setspeed: This attribute can never be used with Intel P-State.
+
+scaling_max_freq/scaling_min_freq: This interface can be used similarly to
+the max_perf_pct/min_perf_pct of Intel P-State sysfs. However since frequencies
+are converted to nearest possible P-State, this is prone to rounding errors.
+This method is not preferred to limit performance.
+
+affected_cpus: Not used
+related_cpus: Not used
+
For contemporary Intel processors, the frequency is controlled by the
-processor itself and the P-states exposed to software are related to
+processor itself and the P-State exposed to software is related to
performance levels. The idea that frequency can be set to a single
-frequency is fiction for Intel Core processors. Even if the scaling
-driver selects a single P state the actual frequency the processor
+frequency is fictional for Intel Core processors. Even if the scaling
+driver selects a single P-State, the actual frequency the processor
will run at is selected by the processor itself.

+When HWP mode is not used, debugfs files have also been added to allow the
+tuning of the internal governor algorithm. These files are located at
+/sys/kernel/debug/pstate_snb/. The algorithm uses a PID (Proportional

p_gain_pct
sample_rate_ms
setpoint
+
+To adjust these parameters, some understanding of driver implementation is
+necessary. There are some tweeks described here, but be very careful. Adjusting
+them requires expert level understanding of power and performance relationship.
+These limits are only useful when the "powersave" policy is active.
+
+-To make the system more responsive to load changes, sample_rate_ms can
+be adjusted (current default is 10ms).
+-To make the system use higher performance, even if the load is lower, setpoint
+can be adjusted to a lower number. This will also lead to faster ramp up time
+to reach the maximum P-State.
+If there are no derivative and integral coefficients, The next P-State will be
+equal to:
+ current P-State - ((setpoint - current cpu load) * p_gain_pct)
+
+For example, if the current PID parameters are (Which are defaults for the core
+processors like SandyBridge):
+ deadband = 0
+ d_gain_pct = 0
+ i_gain_pct = 0
+ p_gain_pct = 20
+ sample_rate_ms = 10
+ setpoint = 97
+
+If the current P-State = 0x08 and current load = 100, this will result in the
+next P-State = 0x08 - ((97 - 100) * 0.2) = 8.6 (rounded to 9). Here the P-State
+goes up by only 1. If during next sample interval the current load doesn't
+change and still 100, then P-State goes up by one again. This process will
+continue as long as the load is more than the setpoint until the maximum P-State
+is reached.
+
+For the same load at setpoint = 60, this will result in the next P-State
+= 0x08 - ((60 - 100) * 0.2) = 16
+So by changing the setpoint from 97 to 60, there is an increase of the
+next P-State from 9 to 16. So this will make processor execute at higher
+P-State for the same CPU load. If the load continues to be more than the
+setpoint during next sample intervals, then P-State will go up again till the
+maximum P-State is reached. But the ramp up time to reach the maximum P-State
+will be much faster when the setpoint is 60 compared to 97.
+
+Debugging Intel P-State driver
+
+Event tracing
+To debug P-State transition, the Linux event tracing interface can be used.
+There are two specific events, which can be enabled (Provided the kernel
+configs related to event tracing are enabled).
+
+# cd /sys/kernel/debug/tracing/
+# echo 1 > events/power/pstate_sample/enable

+If function level tracing is required, the Linux ftrace interface can be used.

+called, we can set ftrace filter to intel_pstate_set_pstate.

+ - dynamic-power-coefficient
+ Usage: optional
+ Value type: <prop-encoded-array>
+ Definition: A u32 value that represents the running time dynamic
+ power coefficient in units of mW/MHz/uVolt^2. The
+ coefficient can either be calculated from power
+ measurements or derived by analysis.
+
+ The dynamic power consumption of the CPU is
+ proportional to the square of the Voltage (V) and
+ the clock frequency (f). The coefficient is used to
+ calculate the dynamic power as below -
+
+ Pdyn = dynamic-power-coefficient * V^2 * f
+
+ where voltage is in uV, frequency is in MHz.

+* ARM Secure world bindings
+
+ARM CPUs with TrustZone support have two distinct address spaces,
+"Normal" and "Secure". Most devicetree consumers (including the Linux
+kernel) are not TrustZone aware and run entirely in either the Normal
+world or the Secure world. However some devicetree consumers are
+TrustZone aware and need to be able to determine whether devices are
+visible only in the Secure address space, only in the Normal address
+space, or visible in both. (One example of that situation would be a
+virtual machine which boots Secure firmware and wants to tell the
+firmware about the layout of the machine via devicetree.)
+
+The general principle of the naming scheme for Secure world bindings
+is that any property that needs a different value in the Secure world
+can be supported by prefixing the property name with "secure-". So for
+instance "secure-foo" would override "foo". For property names with
+a vendor prefix, the Secure variant of "vendor,foo" would be
+"vendor,secure-foo". If there is no "secure-" property then the Secure
+world value is the same as specified for the Normal world by the
+non-prefixed property. However, only the properties listed below may
+validly have "secure-" versions; this list will be enlarged on a
+case-by-case basis.
+
+Defining the bindings in this way means that a device tree which has
+been annotated to indicate the presence of Secure-only devices can
+still be processed unmodified by existing Non-secure software (and in
+particular by the kernel).
+
+Note that it is still valid for bindings intended for purely Secure
+world consumers (like kernels that run entirely in Secure) to simply
+describe the view of Secure world using the standard bindings. These
+secure- bindings only need to be used where both the Secure and Normal
+world views need to be described in a single device tree.
+
+Valid Secure world properties:
+
+- secure-status : specifies whether the device is present and usable
+ in the secure world. The combination of this with "status" allows
+ the various possible combinations of device visibility to be
+ specified. If "secure-status" is not specified it defaults to the
+ same value as "status"; if "status" is not specified either then
+ both default to "okay". This means the following combinations are
+ possible:
+
+ /* Neither specified: default to visible in both S and NS */
+ secure-status = "okay"; /* visible in both */
+ status = "okay"; /* visible in both */
+ status = "okay"; secure-status = "okay"; /* visible in both */
+ secure-status = "disabled"; /* NS-only */
+ status = "okay"; secure-status = "disabled"; /* NS-only */
+ status = "disabled"; secure-status = "okay"; /* S-only */
+ status = "disabled"; /* disabled in both */
+ status = "disabled"; secure-status = "disabled"; /* disabled in both */

+UniPhier System Bus
+
+The UniPhier System Bus is an external bus that connects on-board devices to
+the UniPhier SoC. It is a simple (semi-)parallel bus with address, data, and
+some control signals. It supports up to 8 banks (chip selects).
+
+Before any access to the bus, the bus controller must be configured; the bus
+controller registers provide the control for the translation from the offset
+within each bank to the CPU-viewed address. The needed setup includes the base
+address, the size of each bank. Optionally, some timing parameters can be
+optimized for faster bus access.
+
+Required properties:
+- compatible: should be "socionext,uniphier-system-bus".
+- reg: offset and length of the register set for the bus controller device.
+- #address-cells: should be 2. The first cell is the bank number (chip select).
+ The second cell is the address offset within the bank.
+- #size-cells: should be 1.
+- ranges: should provide a proper address translation from the System Bus to
+ the parent bus.
+
+Note:
+The address region(s) that can be assigned for the System Bus is implementation
+defined. Some SoCs can use 0x00000000-0x0fffffff and 0x40000000-0x4fffffff,
+while other SoCs can only use 0x40000000-0x4fffffff. There might be additional
+limitations depending on SoCs and the boot mode. The address translation is
+arbitrary as long as the banks are assigned in the supported address space with
+the required alignment and they do not overlap one another.
+For example, it is possible to map:
+ bank 0 to 0x42000000-0x43ffffff, bank 5 to 0x46000000-0x46ffffff
+It is also possible to map:
+ bank 0 to 0x48000000-0x49ffffff, bank 5 to 0x44000000-0x44ffffff
+There is no reason to stick to a particular translation mapping, but the
+"ranges" property should provide a "reasonable" default that is known to work.
+The software should initialize the bus controller according to it.
+
+Example:
+
+ system-bus {
+ compatible = "socionext,uniphier-system-bus";
+ reg = <0x58c00000 0x400>;
+ #address-cells = <2>;
+ #size-cells = <1>;
+ ranges = <1 0x00000000 0x42000000 0x02000000
+ 5 0x00000000 0x46000000 0x01000000>;
+
+ ethernet@1,01f00000 {
+ compatible = "smsc,lan9115";
+ reg = <1 0x01f00000 0x1000>;
+ interrupts = <0 48 4>
+ phy-mode = "mii";
+ };
+
+ uart@5,00200000 {
+ compatible = "ns16550a";
+ reg = <5 0x00200000 0x20>;
+ interrupts = <0 49 4>
+ clock-frequency = <12288000>;
+ };
+ };
+
+In this example,
+ - the Ethernet device is connected at the offset 0x01f00000 of CS1 and
+ mapped to 0x43f00000 of the parent bus.
+ - the UART device is connected at the offset 0x00200000 of CS5 and
+ mapped to 0x46200000 of the parent bus.

+ARM System Controller ICST clocks
+
+The ICS525 and ICS307 oscillators are produced by Integrated Devices
+Technology (IDT). ARM integrated these oscillators deeply into their
+reference designs by adding special control registers that manage such
+oscillators to their system controllers.
+
+The ARM system controller contains logic to serialize and initialize
+an ICST clock request after a write to the 32 bit register at an offset
+into the system controller. Furthermore, to even be able to alter one of
+these frequencies, the system controller must first be unlocked by
+writing a special token to another offset in the system controller.
+
+The ICST oscillator must be provided inside a system controller node.
+
+Required properties:
+- lock-offset: the offset address into the system controller where the
+ unlocking register is located
+- vco-offset: the offset address into the system controller where the
+ ICST control register is located (even 32 bit address)
+- compatible: must be one of "arm,syscon-icst525" or "arm,syscon-icst307"
+- #clock-cells: must be <0>
+- clocks: parent clock, since the ICST needs a parent clock to derive its
+ frequency from, this attribute is compulsory.

+Binding for Samsung S2M and S5M family clock generator block
+============================================================
+
+This is a part of device tree bindings for S2M and S5M family multi-function
+devices.
+More information can be found in bindings/mfd/sec-core.txt file.
+
+The S2MPS11/13/15 and S5M8767 provide three(AP/CP/BT) buffered 32.768 kHz
+outputs. The S2MPS14 provides two (AP/BT) buffered 32.768 KHz outputs.
+
+To register these as clocks with common clock framework instantiate under
+main device node a sub-node named "clocks".
+
+It uses the common clock binding documented in:
+ - Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+
+Required properties of the "clocks" sub-node:
+ - #clock-cells: should be 1.
+ - compatible: Should be one of: "samsung,s2mps11-clk", "samsung,s2mps13-clk",
+ "samsung,s2mps14-clk", "samsung,s5m8767-clk"
+ The S2MPS15 uses the same compatible as S2MPS13, as both provides similar
+ clocks.
+
+
+Each clock is assigned an identifier and client nodes use this identifier
+to specify the clock which they consume.

+Binding for ST's CPUFreq driver
+===============================
+
+ST's CPUFreq driver attempts to read 'process' and 'version' attributes
+from the SoC, then supplies the OPP framework with 'prop' and 'supported
+hardware' information respectively. The framework is then able to read
+the DT and operate in the usual way.
+
+For more information about the expected DT format [See: ../opp/opp.txt].
+
+Frequency Scaling only
+----------------------
+
+No vendor specific driver required for this.
+
+Located in CPU's node:
+
+- operating-points : [See: ../power/opp.txt]

+* STMicroelectronics STM32 DMA controller
+
+The STM32 DMA is a general-purpose direct memory access controller capable of
+supporting 8 independent DMA channels. Each channel can have up to 8 requests.
+
+Required properties:
+- compatible: Should be "st,stm32-dma"
+- reg: Should contain DMA registers location and length. This should include
+ all of the per-channel registers.
+- interrupts: Should contain all of the per-channel DMA interrupts in
+ ascending order with respect to the DMA channel index.
+- clocks: Should contain the input clock of the DMA instance.
+- #dma-cells : Must be <4>. See DMA client paragraph for more details.
+
+Optional properties:
+- resets: Reference to a reset controller asserting the DMA controller
+- st,mem2mem: boolean; if defined, it indicates that the controller supports
+ memory-to-memory transfer
+
+Example:
+
+ dma2: dma-controller@40026400 {
+ compatible = "st,stm32-dma";
+ reg = <0x40026400 0x400>;
+ interrupts = <56>,
+ <57>,
+ <58>,
+ <59>,
+ <60>,
+ <68>,
+ <69>,
+ <70>;
+ clocks = <&clk_hclk>;
+ #dma-cells = <4>;
+ st,mem2mem;
+ resets = <&rcc 150>;
+ };
+
+* DMA client
+
+DMA clients connected to the STM32 DMA controller must use the format
+described in the dma.txt file, using a five-cell specifier for each
+channel: a phandle plus four integer cells.
+The four cells in order are:
+
+1. The channel id
+2. The request line number
+3. A 32bit mask specifying the DMA channel configuration which are device
+ dependent:
+ -bit 9: Peripheral Increment Address
+ 0x0: no address increment between transfers
+ 0x1: increment address between transfers
+ -bit 10: Memory Increment Address
+ 0x0: no address increment between transfers
+ 0x1: increment address between transfers
+ -bit 15: Peripheral Increment Offset Size
+ 0x0: offset size is linked to the peripheral bus width
+ 0x1: offset size is fixed to 4 (32-bit alignment)
+ -bit 16-17: Priority level
+ 0x0: low
+ 0x1: medium
+ 0x2: high
+ 0x3: very high
+5. A 32bit mask specifying the DMA FIFO threshold configuration which are device
+ dependent:
+ -bit 0-1: Fifo threshold
+ 0x0: 1/4 full FIFO
+ 0x1: 1/2 full FIFO
+ 0x2: 3/4 full FIFO
+ 0x3: full FIFO
+
+Example:
+
+ usart1: serial@40011000 {
+ compatible = "st,stm32-usart", "st,stm32-uart";
+ reg = <0x40011000 0x400>;

+* Ingenic JZ4780 NAND/BCH
+
+This file documents the device tree bindings for NAND flash devices on the
+JZ4780. NAND devices are connected to the NEMC controller (described in
+memory-controllers/ingenic,jz4780-nemc.txt), and thus NAND device nodes must
+be children of the NEMC node.
+
+Required NAND controller device properties:
+- compatible: Should be set to "ingenic,jz4780-nand".
+- reg: For each bank with a NAND chip attached, should specify a bank number,
+ an offset of 0 and a size of 0x1000000 (i.e. the whole NEMC bank).
+
+Optional NAND controller device properties:
+- ingenic,bch-controller: To make use of the hardware BCH controller, this
+ property must contain a phandle for the BCH controller node. The required
+ properties for this node are described below. If this is not specified,
+ software BCH will be used instead.
+
+Optional children nodes:
+- Individual NAND chips are children of the NAND controller node.
+
+Required children node properties:
+- reg: An integer ranging from 1 to 6 representing the CS line to use.
+
+Optional children node properties:
+- nand-ecc-step-size: ECC block size in bytes.
+- nand-ecc-strength: ECC strength (max number of correctable bits).
+- nand-ecc-mode: String, operation mode of the NAND ecc mode. "hw" by default
+- nand-on-flash-bbt: boolean to enable on flash bbt option, if not present false
+- rb-gpios: GPIO specifier for the busy pin.
+- wp-gpios: GPIO specifier for the write protect pin.
+
+Optional child node of NAND chip nodes:
+- partitions: see Documentation/devicetree/bindings/mtd/partition.txt
+
+Example:
+
+nemc: nemc@13410000 {
+ ...
+
+ nandc: nand-controller@1 {
+ compatible = "ingenic,jz4780-nand";
+ reg = <1 0 0x1000000>; /* Bank 1 */

+* Renesas R-Car generation 3 USB 2.0 PHY
+
+This file provides information on what the device node for the R-Car generation
+3 USB 2.0 PHY contains.
+
+Required properties:
+- compatible: "renesas,usb2-phy-r8a7795" if the device is a part of an R8A7795
+ SoC.
+- reg: offset and length of the partial USB 2.0 Host register block.
+- reg-names: must be "usb2_host".
+- clocks: clock phandle and specifier pair(s).
+- #phy-cells: see phy-bindings.txt in the same directory, must be <0>.
+
+Optional properties:
+To use a USB channel where USB 2.0 Host and HSUSB (USB 2.0 Peripheral) are
+combined, the device tree node should set HSUSB properties to reg and reg-names
+properties. This is because HSUSB has registers to select USB 2.0 host or
+peripheral at that channel:
+- reg: offset and length of the partial HSUSB register block.
+- reg-names: must be "hsusb".
+- interrupts: interrupt specifier for the PHY.

+Example (R-Car H3):
+
+ usb-phy@ee080200 {
+ compatible = "renesas,usb2-phy-r8a7795";
+ reg = <0 0xee080200 0 0x700>, <0 0xe6590100 0 0x100>;

+The S2MPA01 device provide buck and LDO regulators.
+

+
+Optional properties of buck regulator nodes under "regulators" sub-node:
+ - regulator-ramp-delay: ramp delay in uV/us. May be 6250, 12500
+ (default), 25000, or 50000. May be 0 for disabling the ramp delay on

+ will be set for a particular group of bucks so provide the same
+ regulator-ramp-delay value for them.
+ Groups sharing ramp rate:
+ - buck{1,6},
+ - buck{2,4},

+
+The HiSilicon SAS controller supports SAS/SATA.
+
+Main node required properties:
+ - compatible : value should be as follows:
+ (a) "hisilicon,hip05-sas-v1" for v1 hw in hip05 chipset
+ - sas-addr : array of 8 bytes for host SAS address
+ - reg : Address and length of the SAS register
+ - hisilicon,sas-syscon: phandle of syscon used for sas control
+ - ctrl-reset-reg : offset to controller reset register in ctrl reg
+ - ctrl-reset-sts-reg : offset to controller reset status register in ctrl reg
+ - ctrl-clock-ena-reg : offset to controller clock enable register in ctrl reg
+ - queue-count : number of delivery and completion queues in the controller
+ - phy-count : number of phys accessible by the controller
+ - interrupts : Interrupts for phys, completion queues, and fatal
+ sources; the interrupts are ordered in 3 groups, as follows:
+ - Phy interrupts
+ - Completion queue interrupts
+ - Fatal interrupts
+ Phy interrupts : Each phy has 3 interrupt sources:
+ - broadcast
+ - phyup
+ - abnormal
+ The phy interrupts are ordered into groups of 3 per phy
+ (broadcast, phyup, and abnormal) in increasing order.
+ Completion queue interrupts : each completion queue has 1
+ interrupt source.

+Qualcomm Shared Memory State Machine
+
+The Shared Memory State Machine facilitates broadcasting of single bit state
+information between the processors in a Qualcomm SoC. Each processor is
+assigned 32 bits of state that can be modified. A processor can through a
+matrix of bitmaps signal subscription of notifications upon changes to a
+certain bit owned by a certain remote processor.
+
+- compatible:
+ Usage: required
+ Value type: <string>
+ Definition: must be one of:
+ "qcom,smsm"
+
+- qcom,ipc-N:
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: three entries specifying the outgoing ipc bit used for
+ signaling the N:th remote processor
+ - phandle to a syscon node representing the apcs registers
+ - u32 representing offset to the register within the syscon
+ - u32 representing the ipc bit within the register
+
+- qcom,local-host:
+ Usage: optional
+ Value type: <u32>
+ Definition: identifier of the local processor in the list of hosts, or
+ in other words specifier of the column in the subscription
+ matrix representing the local processor
+ defaults to host 0
+
+- #address-cells:
+ Usage: required
+ Value type: <u32>
+ Definition: must be 1
+
+- #size-cells:
+ Usage: required
+ Value type: <u32>
+ Definition: must be 0
+
+= SUBNODES
+Each processor's state bits are described by a subnode of the smsm device node.
+Nodes can either be flagged as an interrupt-controller to denote a remote
+processor's state bits or the local processors bits. The node names are not
+important.
+
+- reg:
+ Usage: required
+ Value type: <u32>
+ Definition: specifies the offset, in words, of the first bit for this
+ entry
+
+- #qcom,state-cells:
+ Usage: required for local entry
+ Value type: <u32>
+ Definition: must be 1 - denotes bit number
+
+- interrupt-controller:
+ Usage: required for remote entries
+ Value type: <empty>
+ Definition: marks the entry as a interrupt-controller and the state bits
+ to belong to a remote processor
+
+- #interrupt-cells:
+ Usage: required for remote entries
+ Value type: <u32>
+ Definition: must be 2 - denotes bit number and IRQ flags
+
+- interrupts:
+ Usage: required for remote entries
+ Value type: <prop-encoded-array>
+ Definition: one entry specifying remote IRQ used by the remote processor

+Wakeup M3 IPC Driver
+=====================
+
+The TI AM33xx and AM43xx family of devices use a small Cortex M3 co-processor
+(commonly referred to as Wakeup M3 or CM3) to help with various low power tasks
+that cannot be controlled from the MPU, like suspend/resume and certain deep
+C-states for CPU Idle. Once the wkup_m3_ipc driver uses the wkup_m3_rproc driver
+to boot the wkup_m3, it handles communication with the CM3 using IPC registers
+present in the SoC's control module and a mailbox. The wkup_m3_ipc exposes an
+API to allow the SoC PM code to execute specific PM tasks.
+
+Wkup M3 Device Node:
+====================
+A wkup_m3_ipc device node is used to represent the IPC registers within an
+SoC.
+
+Required properties:
+--------------------
+- compatible: Should be,
+ "ti,am3352-wkup-m3-ipc" for AM33xx SoCs
+ "ti,am4372-wkup-m3-ipc" for AM43xx SoCs
+- reg: Contains the IPC register address space to communicate
+ with the Wakeup M3 processor
+- interrupts: Contains the interrupt information for the wkup_m3
+ interrupt that signals the MPU.
+- ti,rproc: phandle to the wkup_m3 rproc node so the IPC driver
+ can boot it.
+- mboxes: phandles used by IPC framework to get correct mbox
+ channel for communication. Must point to appropriate
+ mbox_wkupm3 child node.
+
+Example:
+--------
+/* AM33xx */
+ l4_wkup: l4_wkup@44c00000 {
+ ...
+
+ scm: scm@210000 {

+Industrial IIO configfs support
+
+1. Overview
+
+Configfs is a filesystem-based manager of kernel objects. IIO uses some
+objects that could be easily configured using configfs (e.g.: devices,
+triggers).
+
+See Documentation/filesystems/configfs/configfs.txt for more information
+about how configfs works.
+
+2. Usage
+
+In order to use configfs support in IIO we need to select it at compile
+time via CONFIG_IIO_CONFIGFS config option.
+
+Then, mount the configfs filesystem (usually under /config directory):
+
+$ mkdir /config
+$ mount -t configfs none /config
+
+At this point, all default IIO groups will be created and can be accessed
+under /config/iio. Next chapters will describe available IIO configuration
+objects.
+
+3. Software triggers
+
+One of the IIO default configfs groups is the "triggers" group. It is
+automagically accessible when the configfs is mounted and can be found
+under /config/iio/triggers.
+
+IIO software triggers implementation offers support for creating multiple
+trigger types. A new trigger type is usually implemented as a separate
+kernel module following the interface in include/linux/iio/sw_trigger.h:
+
+/*
+ * drivers/iio/trigger/iio-trig-sample.c
+ * sample kernel module implementing a new trigger type
+ */
+#include <linux/iio/sw_trigger.h>
+
+
+static struct iio_sw_trigger *iio_trig_sample_probe(const char *name)
+{
+ /*
+ * This allocates and registers an IIO trigger plus other
+ * trigger type specific initialization.
+ */
+}
+
+static int iio_trig_hrtimer_remove(struct iio_sw_trigger *swt)
+{
+ /*
+ * This undoes the actions in iio_trig_sample_probe
+ */
+}
+
+static const struct iio_sw_trigger_ops iio_trig_sample_ops = {
+ .probe = iio_trig_sample_probe,
+ .remove = iio_trig_sample_remove,
+};
+
+static struct iio_sw_trigger_type iio_trig_sample = {
+ .name = "trig-sample",
+ .owner = THIS_MODULE,
+ .ops = &iio_trig_sample_ops,
+};
+
+module_iio_sw_trigger_driver(iio_trig_sample);
+
+Each trigger type has its own directory under /config/iio/triggers. Loading
+iio-trig-sample module will create 'trig-sample' trigger type directory
+/config/iio/triggers/trig-sample.
+
+We support the following interrupt sources (trigger types):
+ * hrtimer, uses high resolution timers as interrupt source
+
+3.1 Hrtimer triggers creation and destruction
+
+Loading iio-trig-hrtimer module will register hrtimer trigger types allowing
+users to create hrtimer triggers under /config/iio/triggers/hrtimer.
+
+e.g:
+
+$ mkdir /config/triggers/hrtimer/instance1
+$ rmdir /config/triggers/hrtimer/instance1
+
+Each trigger can have one or more attributes specific to the trigger type.
+
+3.2 "hrtimer" trigger types attributes
+
+"hrtimer" trigger type doesn't have any configurable attribute from /config dir.
+It does introduce the sampling_frequency attribute to trigger directory.

2. DLM Locks for management
-There are two locks for managing the device:
+There are three groups of locks for managing the device:
2.1 Bitmap lock resource (bm_lockres)
- The bm_lockres protects individual node bitmaps. They are named in the
- form bitmap001 for node 1, bitmap002 for node and so on. When a node
- joins the cluster, it acquires the lock in PW mode and it stays so
- during the lifetime the node is part of the cluster. The lock resource
- number is based on the slot number returned by the DLM subsystem. Since
- DLM starts node count from one and bitmap slots start from zero, one is
- subtracted from the DLM slot number to arrive at the bitmap slot number.
+ The bm_lockres protects individual node bitmaps. They are named in

+ resource number is based on the slot number returned by the DLM
+ subsystem. Since DLM starts node count from one and bitmap slots
+ start from zero, one is subtracted from the DLM slot number to arrive
+ at the bitmap slot number.
+
+ The LVB of the bitmap lock for a particular node records the range
+ of sectors that are being re-synced by that node. No other
+ node may write to those sectors. This is used when a new nodes
+ joins the cluster.
+
+2.2 Message passing locks
+
+ Each node has to communicate with other nodes when starting or ending
+ resync, and for metadata superblock updates. This communication is
+ managed through three locks: "token", "message", and "ack", together
+ with the Lock Value Block (LVB) of one of the "message" lock.
+
+2.3 new-device management
+
+ A single lock: "no-new-dev" is used to co-ordinate the addition of
+ new devices - this must be synchronized across the array.
+ Normally all nodes hold a concurrent-read lock on this device.
3. Communication
-Each node has to communicate with other nodes when starting or ending
-resync, and metadata superblock updates.
+ Messages can be broadcast to all nodes, and the sender waits for all
+ other nodes to acknowledge the message before proceeding. Only one
+ message can be processed at a time.
3.1 Message Types
- There are 3 types, of messages which are passed
+ There are six types of messages which are passed:
- 3.1.1 METADATA_UPDATED: informs other nodes that the metadata has been
- updated, and the node must re-read the md superblock. This is performed
- synchronously.
+ 3.1.1 METADATA_UPDATED: informs other nodes that the metadata has
+ been updated, and the node must re-read the md superblock. This is
+ performed synchronously. It is primarily used to signal device
+ failure.
- 3.1.2 RESYNC: informs other nodes that a resync is initiated or ended
- so that each node may suspend or resume the region.
+ 3.1.2 RESYNCING: informs other nodes that a resync is initiated or
+ ended so that each node may suspend or resume the region. Each
+ RESYNCING message identifies a range of the devices that the
+ sending node is about to resync. This over-rides any pervious
+ notification from that node: only one ranged can be resynced at a
+ time per-node.
+
+ 3.1.3 NEWDISK: informs other nodes that a device is being added to
+ the array. Message contains an identifier for that device. See
+ below for further details.
+
+ 3.1.4 REMOVE: A failed or spare device is being removed from the
+ array. The slot-number of the device is included in the message.
+
+ 3.1.5 RE_ADD: A failed device is being re-activated - the assumption
+ is that it has been determined to be working again.
+
+ 3.1.6 BITMAP_NEEDS_SYNC: if a node is stopped locally but the bitmap
+ isn't clean, then another node is informed to take the ownership of
+ resync.
3.2 Communication mechanism
The DLM LVB is used to communicate within nodes of the cluster. There
are three resources used for the purpose:
- 3.2.1 Token: The resource which protects the entire communication
+ 3.2.1 token: The resource which protects the entire communication

+
+6. Module interface.
+
+ There are 17 call-backs which the md core can make to the cluster
+ module. Understanding these can give a good overview of the whole
+ process.
+
+6.1 join(nodes) and leave()
+
+ These are called when an array is started with a clustered bitmap,
+ and when the array is stopped. join() ensures the cluster is
+ available and initializes the various resources.
+ Only the first 'nodes' nodes in the cluster can use the array.
+
+6.2 slot_number()
+
+ Reports the slot number advised by the cluster infrastructure.
+ Range is from 0 to nodes-1.
+
+6.3 resync_info_update()
+
+ This updates the resync range that is stored in the bitmap lock.
+ The starting point is updated as the resync progresses. The
+ end point is always the end of the array.
+ It does *not* send a RESYNCING message.
+
+6.4 resync_start(), resync_finish()
+
+ These are called when resync/recovery/reshape starts or stops.
+ They update the resyncing range in the bitmap lock and also
+ send a RESYNCING message. resync_start reports the whole
+ array as resyncing, resync_finish reports none of it.
+
+ resync_finish() also sends a BITMAP_NEEDS_SYNC message which
+ allows some other node to take over.
+
+6.5 metadata_update_start(), metadata_update_finish(),
+ metadata_update_cancel().
+
+ metadata_update_start is used to get exclusive access to
+ the metadata. If a change is still needed once that access is
+ gained, metadata_update_finish() will send a METADATA_UPDATE
+ message to all other nodes, otherwise metadata_update_cancel()
+ can be used to release the lock.
+
+6.6 area_resyncing()
+
+ This combines two elements of functionality.
+
+ Firstly, it will check if any node is currently resyncing
+ anything in a given range of sectors. If any resync is found,
+ then the caller will avoid writing or read-balancing in that
+ range.
+
+ Secondly, while node recovery is happening it reports that
+ all areas are resyncing for READ requests. This avoids races
+ between the cluster-filesystem and the cluster-RAID handling
+ a node failure.
+
+6.7 add_new_disk_start(), add_new_disk_finish(), new_disk_ack()
+
+ These are used to manage the new-disk protocol described above.
+ When a new device is added, add_new_disk_start() is called before
+ it is bound to the array and, if that succeeds, add_new_disk_finish()
+ is called the device is fully added.
+
+ When a device is added in acknowledgement to a previous
+ request, or when the device is declared "unavailable",
+ new_disk_ack() is called.
+
+6.8 remove_disk()
+
+ This is called when a spare or failed device is removed from
+ the array. It causes a REMOVE message to be send to other nodes.
+
+6.9 gather_bitmaps()
+
+ This sends a RE_ADD message to all other nodes and then
+ gathers bitmap information from all bitmaps. This combined
+ bitmap is then used to recovery the re-added device.
+
+6.10 lock_all_bitmaps() and unlock_all_bitmaps()
+
+ These are called when change bitmap to none. If a node plans
+ to clear the cluster raid's bitmap, it need to make sure no other
+ nodes are using the raid which is achieved by lock all bitmap
+ locks within the cluster, and also those locks are unlocked
+ accordingly.

-Linux kernel media framework
-============================
-
-This document describes the Linux kernel media framework, its data structures,
-functions and their usage.
-
-
-Introduction
-------------
-
-The media controller API is documented in DocBook format in
-Documentation/DocBook/media/v4l/media-controller.xml. This document will focus
-on the kernel-side implementation of the media framework.
-
-
-Abstract media device model
----------------------------
-
-Discovering a device internal topology, and configuring it at runtime, is one
-of the goals of the media framework. To achieve this, hardware devices are
-modelled as an oriented graph of building blocks called entities connected
-through pads.
-
-An entity is a basic media hardware building block. It can correspond to
-a large variety of logical blocks such as physical hardware devices
-(CMOS sensor for instance), logical hardware devices (a building block
-in a System-on-Chip image processing pipeline), DMA channels or physical
-connectors.
-
-A pad is a connection endpoint through which an entity can interact with
-other entities. Data (not restricted to video) produced by an entity
-flows from the entity's output to one or more entity inputs. Pads should
-not be confused with physical pins at chip boundaries.
-
-A link is a point-to-point oriented connection between two pads, either
-on the same entity or on different entities. Data flows from a source
-pad to a sink pad.
-
-
-Media device
-------------
-
-A media device is represented by a struct media_device instance, defined in
-include/media/media-device.h. Allocation of the structure is handled by the
-media device driver, usually by embedding the media_device instance in a
-larger driver-specific structure.
-
-Drivers register media device instances by calling
-
- media_device_register(struct media_device *mdev);
-
-The caller is responsible for initializing the media_device structure before
-registration. The following fields must be set:
-
- - dev must point to the parent device (usually a pci_dev, usb_interface or
- platform_device instance).
-
- - model must be filled with the device model name as a NUL-terminated UTF-8
- string. The device/model revision must not be stored in this field.
-
-The following fields are optional:
-
- - serial is a unique serial number stored as a NUL-terminated ASCII string.
- The field is big enough to store a GUID in text form. If the hardware
- doesn't provide a unique serial number this field must be left empty.
-
- - bus_info represents the location of the device in the system as a
- NUL-terminated ASCII string. For PCI/PCIe devices bus_info must be set to
- "PCI:" (or "PCIe:") followed by the value of pci_name(). For USB devices,
- the usb_make_path() function must be used. This field is used by
- applications to distinguish between otherwise identical devices that don't
- provide a serial number.
-
- - hw_revision is the hardware device revision in a driver-specific format.
- When possible the revision should be formatted with the KERNEL_VERSION
- macro.
-
- - driver_version is formatted with the KERNEL_VERSION macro. The version
- minor must be incremented when new features are added to the userspace API
- without breaking binary compatibility. The version major must be
- incremented when binary compatibility is broken.
-
-Upon successful registration a character device named media[0-9]+ is created.
-The device major and minor numbers are dynamic. The model name is exported as
-a sysfs attribute.
-
-Drivers unregister media device instances by calling
-
- media_device_unregister(struct media_device *mdev);
-
-Unregistering a media device that hasn't been registered is *NOT* safe.
-
-
-Entities, pads and links
-------------------------
-
-- Entities
-
-Entities are represented by a struct media_entity instance, defined in
-include/media/media-entity.h. The structure is usually embedded into a
-higher-level structure, such as a v4l2_subdev or video_device instance,
-although drivers can allocate entities directly.
-
-Drivers initialize entities by calling
-
- media_entity_init(struct media_entity *entity, u16 num_pads,
- struct media_pad *pads, u16 extra_links);
-
-The media_entity name, type, flags, revision and group_id fields can be
-initialized before or after calling media_entity_init. Entities embedded in
-higher-level standard structures can have some of those fields set by the
-higher-level framework.
-
-As the number of pads is known in advance, the pads array is not allocated
-dynamically but is managed by the entity driver. Most drivers will embed the
-pads array in a driver-specific structure, avoiding dynamic allocation.
-
-Drivers must set the direction of every pad in the pads array before calling
-media_entity_init. The function will initialize the other pads fields.
-
-Unlike the number of pads, the total number of links isn't always known in
-advance by the entity driver. As an initial estimate, media_entity_init
-pre-allocates a number of links equal to the number of pads plus an optional
-number of extra links. The links array will be reallocated if it grows beyond
-the initial estimate.
-
-Drivers register entities with a media device by calling
-
- media_device_register_entity(struct media_device *mdev,
- struct media_entity *entity);
-
-Entities are identified by a unique positive integer ID. Drivers can provide an
-ID by filling the media_entity id field prior to registration, or request the
-media controller framework to assign an ID automatically. Drivers that provide
-IDs manually must ensure that all IDs are unique. IDs are not guaranteed to be
-contiguous even when they are all assigned automatically by the framework.
-
-Drivers unregister entities by calling
-
- media_device_unregister_entity(struct media_entity *entity);
-
-Unregistering an entity will not change the IDs of the other entities, and the
-ID will never be reused for a newly registered entity.
-
-When a media device is unregistered, all its entities are unregistered
-automatically. No manual entities unregistration is then required.
-
-Drivers free resources associated with an entity by calling
-
- media_entity_cleanup(struct media_entity *entity);
-
-This function must be called during the cleanup phase after unregistering the
-entity. Note that the media_entity instance itself must be freed explicitly by
-the driver if required.
-
-Entities have flags that describe the entity capabilities and state.
-
- MEDIA_ENT_FL_DEFAULT indicates the default entity for a given type.
- This can be used to report the default audio and video devices or the
- default camera sensor.
-
-Logical entity groups can be defined by setting the group ID of all member
-entities to the same non-zero value. An entity group serves no purpose in the
-kernel, but is reported to userspace during entities enumeration. The group_id
-field belongs to the media device driver and must not by touched by entity
-drivers.
-
-Media device drivers should define groups if several entities are logically
-bound together. Example usages include reporting
-
- - ALSA, VBI and video nodes that carry the same media stream
- - lens and flash controllers associated with a sensor
-
-- Pads
-
-Pads are represented by a struct media_pad instance, defined in
-include/media/media-entity.h. Each entity stores its pads in a pads array
-managed by the entity driver. Drivers usually embed the array in a
-driver-specific structure.
-
-Pads are identified by their entity and their 0-based index in the pads array.
-Both information are stored in the media_pad structure, making the media_pad
-pointer the canonical way to store and pass link references.
-
-Pads have flags that describe the pad capabilities and state.
-
- MEDIA_PAD_FL_SINK indicates that the pad supports sinking data.
- MEDIA_PAD_FL_SOURCE indicates that the pad supports sourcing data.
-
-One and only one of MEDIA_PAD_FL_SINK and MEDIA_PAD_FL_SOURCE must be set for
-each pad.
-
-- Links
-
-Links are represented by a struct media_link instance, defined in
-include/media/media-entity.h. Each entity stores all links originating at or
-targeting any of its pads in a links array. A given link is thus stored
-twice, once in the source entity and once in the target entity. The array is
-pre-allocated and grows dynamically as needed.
-
-Drivers create links by calling
-
- media_entity_create_link(struct media_entity *source, u16 source_pad,
- struct media_entity *sink, u16 sink_pad,
- u32 flags);
-
-An entry in the link array of each entity is allocated and stores pointers
-to source and sink pads.
-
-Links have flags that describe the link capabilities and state.
-
- MEDIA_LNK_FL_ENABLED indicates that the link is enabled and can be used
- to transfer media data. When two or more links target a sink pad, only
- one of them can be enabled at a time.
- MEDIA_LNK_FL_IMMUTABLE indicates that the link enabled state can't be
- modified at runtime. If MEDIA_LNK_FL_IMMUTABLE is set, then
- MEDIA_LNK_FL_ENABLED must also be set since an immutable link is always
- enabled.
-
-
-Graph traversal
----------------
-
-The media framework provides APIs to iterate over entities in a graph.
-
-To iterate over all entities belonging to a media device, drivers can use the
-media_device_for_each_entity macro, defined in include/media/media-device.h.
-
- struct media_entity *entity;
-
- media_device_for_each_entity(entity, mdev) {
- /* entity will point to each entity in turn */
- ...
- }
-
-Drivers might also need to iterate over all entities in a graph that can be
-reached only through enabled links starting at a given entity. The media
-framework provides a depth-first graph traversal API for that purpose.
-
-Note that graphs with cycles (whether directed or undirected) are *NOT*
-supported by the graph traversal API. To prevent infinite loops, the graph
-traversal code limits the maximum depth to MEDIA_ENTITY_ENUM_MAX_DEPTH,
-currently defined as 16.
-
-Drivers initiate a graph traversal by calling
-
- media_entity_graph_walk_start(struct media_entity_graph *graph,
- struct media_entity *entity);
-
-The graph structure, provided by the caller, is initialized to start graph
-traversal at the given entity.
-
-Drivers can then retrieve the next entity by calling
-
- media_entity_graph_walk_next(struct media_entity_graph *graph);
-
-When the graph traversal is complete the function will return NULL.
-
-Graph traversal can be interrupted at any moment. No cleanup function call is
-required and the graph structure can be freed normally.
-
-Helper functions can be used to find a link between two given pads, or a pad
-connected to another pad through an enabled link
-
- media_entity_find_link(struct media_pad *source,
- struct media_pad *sink);
-
- media_entity_remote_pad(struct media_pad *pad);
-
-Refer to the kerneldoc documentation for more information.
-
-
-Use count and power handling
-----------------------------
-
-Due to the wide differences between drivers regarding power management needs,
-the media controller does not implement power management. However, the
-media_entity structure includes a use_count field that media drivers can use to
-track the number of users of every entity for power management needs.
-
-The use_count field is owned by media drivers and must not be touched by entity
-drivers. Access to the field must be protected by the media device graph_mutex
-lock.
-
-
-Links setup
------------
-
-Link properties can be modified at runtime by calling
-
- media_entity_setup_link(struct media_link *link, u32 flags);
-
-The flags argument contains the requested new link flags.
-
-The only configurable property is the ENABLED link flag to enable/disable a
-link. Links marked with the IMMUTABLE link flag can not be enabled or disabled.
-
-When a link is enabled or disabled, the media framework calls the
-link_setup operation for the two entities at the source and sink of the link,
-in that order. If the second link_setup call fails, another link_setup call is
-made on the first entity to restore the original link flags.
-
-Media device drivers can be notified of link setup operations by setting the
-media_device::link_notify pointer to a callback function. If provided, the
-notification callback will be called before enabling and after disabling
-links.
-
-Entity drivers must implement the link_setup operation if any of their links
-is non-immutable. The operation must either configure the hardware or store
-the configuration information to be applied later.
-
-Link configuration must not have any side effect on other links. If an enabled
-link at a sink pad prevents another link at the same pad from being enabled,
-the link_setup operation must return -EBUSY and can't implicitly disable the
-first enabled link.
-
-
-Pipelines and media streams
----------------------------
-
-When starting streaming, drivers must notify all entities in the pipeline to
-prevent link states from being modified during streaming by calling
-
- media_entity_pipeline_start(struct media_entity *entity,
- struct media_pipeline *pipe);
-
-The function will mark all entities connected to the given entity through
-enabled links, either directly or indirectly, as streaming.
-
-The media_pipeline instance pointed to by the pipe argument will be stored in
-every entity in the pipeline. Drivers should embed the media_pipeline structure
-in higher-level pipeline structures and can then access the pipeline through
-the media_entity pipe field.
-
-Calls to media_entity_pipeline_start() can be nested. The pipeline pointer must
-be identical for all nested calls to the function.
-
-media_entity_pipeline_start() may return an error. In that case, it will
-clean up any of the changes it did by itself.
-
-When stopping the stream, drivers must notify the entities with
-
- media_entity_pipeline_stop(struct media_entity *entity);
-
-If multiple calls to media_entity_pipeline_start() have been made the same
-number of media_entity_pipeline_stop() calls are required to stop streaming. The
-media_entity pipe field is reset to NULL on the last nested stop call.
-
-Link configuration will fail with -EBUSY by default if either end of the link is
-a streaming entity. Links that can be modified while streaming must be marked
-with the MEDIA_LNK_FL_DYNAMIC flag.
-
-If other operations need to be disallowed on streaming entities (such as
-changing entities configuration parameters) drivers can explicitly check the
-media_entity stream_count field to find out if an entity is streaming. This
-operation must be done with the media_device graph_mutex held.
-
-
-Link validation
----------------
-
-Link validation is performed by media_entity_pipeline_start() for any
-entity which has sink pads in the pipeline. The
-media_entity::link_validate() callback is used for that purpose. In
-link_validate() callback, entity driver should check that the properties of
-the source pad of the connected entity and its own sink pad match. It is up
-to the type of the entity (and in the end, the properties of the hardware)
-what matching actually means.
-
-Subsystems should facilitate link validation by providing subsystem specific
-helper functions to provide easy access for commonly needed information, and
-in the end provide a way to use driver-specific callbacks.

+Undefined Behavior Sanitizer - UBSAN
+
+Overview
+--------
+
+UBSAN is a runtime undefined behaviour checker.
+
+UBSAN uses compile-time instrumentation to catch undefined behavior (UB).
+Compiler inserts code that perform certain kinds of checks before operations
+that may cause UB. If check fails (i.e. UB detected) __ubsan_handle_*
+function called to print error message.
+
+GCC has that feature since 4.9.x [1] (see -fsanitize=undefined option and
+its suboptions). GCC 5.x has more checkers implemented [2].
+
+Report example

+Usage
+-----
+
+To enable UBSAN configure kernel with:
+
+ CONFIG_UBSAN=y
+
+and to check the entire kernel:
+
+ CONFIG_UBSAN_SANITIZE_ALL=y
+
+To enable instrumentation for specific files or directories, add a line
+similar to the following to the respective kernel Makefile:
+
+ For a single file (e.g. main.o):
+ UBSAN_SANITIZE_main.o := y
+
+ For all files in one directory:
+ UBSAN_SANITIZE := y
+
+To exclude files from being instrumented even if
+CONFIG_UBSAN_SANITIZE_ALL=y, use:
+
+ UBSAN_SANITIZE_main.o := n
+ and:
+ UBSAN_SANITIZE := n
+
+Detection of unaligned accesses controlled through the separate option -
+CONFIG_UBSAN_ALIGNMENT. It's off by default on architectures that support
+unaligned accesses (CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS=y). One could
+still enable it in config, just note that it will produce a lot of UBSAN
+reports.

+before. Otherwise you can proceed to process the huge pmd and the
+hugepage natively. Once finished you can drop the page table lock.
+
+== Refcounts and transparent huge pages ==
+
+Refcounting on THP is mostly consistent with refcounting on other compound
+pages:
+
+ - get_page()/put_page() and GUP operate in head page's ->_count.
+
+ - ->_count in tail pages is always zero: get_page_unless_zero() never
+ succeed on tail pages.
+
+ - map/unmap of the pages with PTE entry increment/decrement ->_mapcount
+ on relevant sub-page of the compound page.
+
+ - map/unmap of the whole compound page accounted in compound_mapcount
+ (stored in first tail page).
+
+PageDoubleMap() indicates that ->_mapcount in all subpages is offset up by one.
+This additional reference is required to get race-free detection of unmap of
+subpages when we have them mapped with both PMDs and PTEs.
+
+This is optimization required to lower overhead of per-subpage mapcount
+tracking. The alternative is alter ->_mapcount in all subpages on each
+map/unmap of the whole compound page.
+
+We set PG_double_map when a PMD of the page got split for the first time,
+but still have PMD mapping. The addtional references go away with last
+compound_mapcount.
split_huge_page internally has to distribute the refcounts in the head
-page to the tail pages before clearing all PG_head/tail bits from the
-page structures. It can do that easily for refcounts taken by huge pmd
-mappings. But the GUI API as created by hugetlbfs (that returns head
-and tail pages if running get_user_pages on an address backed by any
-hugepage), requires the refcount to be accounted on the tail pages and
-not only in the head pages, if we want to be able to run
-split_huge_page while there are gup pins established on any tail
-page. Failure to be able to run split_huge_page if there's any gup pin
-on any tail page, would mean having to split all hugepages upfront in
-get_user_pages which is unacceptable as too many gup users are
-performance critical and they must work natively on hugepages like
-they work natively on hugetlbfs already (hugetlbfs is simpler because
-hugetlbfs pages cannot be split so there wouldn't be requirement of
-accounting the pins on the tail pages for hugetlbfs). If we wouldn't
-account the gup refcounts on the tail pages during gup, we won't know
-anymore which tail page is pinned by gup and which is not while we run
-split_huge_page. But we still have to add the gup pin to the head page
-too, to know when we can free the compound page in case it's never
-split during its lifetime. That requires changing not just
-get_page, but put_page as well so that when put_page runs on a tail
-page (and only on a tail page) it will find its respective head page,
-and then it will decrease the head page refcount in addition to the
-tail page refcount. To obtain a head page reliably and to decrease its
-refcount without race conditions, put_page has to serialize against
-__split_huge_page_refcount using a special per-page lock called
-compound_lock.
+page to the tail pages before clearing all PG_head/tail bits from the page
+structures. It can be done easily for refcounts taken by page table
+entries. But we don't have enough information on how to distribute any
+additional pins (i.e. from get_user_pages). split_huge_page() fails any
+requests to split pinned huge page: it expects page count to be equal to
+sum of mapcount of all sub-pages plus one (split_huge_page caller must
+have reference for head page).
+
+split_huge_page uses migration entries to stabilize page->_count and
+page->_mapcount.
+
+We safe against physical memory scanners too: the only legitimate way
+scanner can get reference to a page is get_page_unless_zero().
+
+All tail pages has zero ->_count until atomic_add(). It prevent scanner
+from geting reference to tail page up to the point. After the atomic_add()
+we don't care about ->_count value. We already known how many references
+with should uncharge from head page.
+
+For head page get_page_unless_zero() will succeed and we don't mind. It's
+clear where reference should go after split: it will stay on head page.
+
+Note that split_huge_pmd() doesn't have any limitation on refcounting:
+pmd can be split at any point and never fails.
+
+== Partial unmap and deferred_split_huge_page() ==
+
+Unmapping part of THP (with munmap() or other way) is not going to free
+memory immediately. Instead, we detect that a subpage of THP is not in use
+in page_remove_rmap() and queue the THP for splitting if memory pressure
+comes. Splitting will free up unused subpages.
+
+Splitting the page right away is not an option due to locking context in
+the place where we can detect partial unmap. It's also might be
+counterproductive since in many cases partial unmap unmap happens during
+exit(2) if an THP crosses VMA boundary.
+
+Function deferred_split_huge_page() is used to queue page for splitting.
+The splitting itself will happen when we get memory pressure via shrinker
+interface.

+ * @maxY: max height for modes
+ *
+ * Based on the helper callbacks implemented by @connector in struct

+ *
+ * Intended to be used as a generic implementation of the ->fill_modes()

+ * filtering and detection.
+ *
+ * The basic procedure is as follows
+ *
+ * 1. All modes currently on the connector's modes list are marked as stale
+ *
+ * 2. New modes are added to the connector's probed_modes list with
+ * drm_mode_probed_add(). New modes start their life with status as OK.
+ * Modes are added from a single source using the following priority order.
+ *
+ * - debugfs 'override_edid' (used for testing only)
+ * - firmware EDID (drm_load_edid_firmware())
+ * - connector helper ->get_modes() vfunc
+ * - if the connector status is connector_status_connected, standard
+ * VESA DMT modes up to 1024x768 are automatically added
+ * (drm_add_modes_noedid())
+ *
+ * Finally modes specified via the kernel command line (video=...) are
+ * added in addition to what the earlier probes produced
+ * (drm_helper_probe_add_cmdline_mode()). These modes are generated
+ * using the VESA GTF/CVT formulas.
+ *
+ * 3. Modes are moved from the probed_modes list to the modes list. Potential
+ * duplicates are merged together (see drm_mode_connector_list_update()).
+ * After this step the probed_modes list will be empty again.
+ *
+ * 4. Any non-stale mode on the modes list then undergoes validation
+ *
+ * - drm_mode_validate_basic() performs basic sanity checks
+ * - drm_mode_validate_size() filters out modes larger than @maxX and @maxY
+ * (if specified)
+ * - drm_mode_validate_flag() checks the modes againt basic connector
+ * capabilites (interlace_allowed,doublescan_allowed,stereo_allowed)
+ * - the optional connector ->mode_valid() helper can perform driver and/or
+ * hardware specific checks
+ *
+ * 5. Any mode whose status is not OK is pruned from the connector's modes list,
+ * accompanied by a debug message indicating the reason for the mode's
+ * rejection (see drm_mode_prune_invalid()).

+ * Details:
+ * When the AUTO mode is the only conversion mode enabled, if the AUTO
+ * mode feature is disabled with bit GPADC_AUTO_CTRL. AUTO_CONV1_EN = 0
+ * or bit GPADC_AUTO_CTRL. AUTO_CONV0_EN = 0 during a conversion, the
+ * conversion mechanism can be seen as locked meaning that all following
+ * conversion will give 0 as a result. Bit GPADC_STATUS.GPADC_AVAILABLE
+ * will stay at 0 meaning that GPADC is busy. An RT conversion can unlock
+ * the GPADC.
+ *
+ * Workaround(s):
+ * To avoid the lock mechanism, the workaround to follow before any stop
+ * conversion request is:
+ * Force the GPADC state machine to be ON by using the GPADC_CTRL1.
+ * GPADC_FORCE bit = 1
+ * Shutdown the GPADC AUTO conversion using
+ * GPADC_AUTO_CTRL.SHUTDOWN_CONV[01] = 0.
+ * After 100us, force the GPADC state machine to be OFF by using the
+ * GPADC_CTRL1. GPADC_FORCE bit = 0

+/*
+ * For DMA buffers the storage is sub-divided into so called blocks. Each block
+ * has its own memory buffer. The size of the block is the granularity at which
+ * memory is exchanged between the hardware and the application. Increasing the
+ * basic unit of data exchange from one sample to one block decreases the
+ * management overhead that is associated with each sample. E.g. if we say the
+ * management overhead for one exchange is x and the unit of exchange is one
+ * sample the overhead will be x for each sample. Whereas when using a block
+ * which contains n samples the overhead per sample is reduced to x/n. This
+ * allows to achieve much higher samplerates than what can be sustained with
+ * the one sample approach.
+ *
+ * Blocks are exchanged between the DMA controller and the application via the
+ * means of two queues. The incoming queue and the outgoing queue. Blocks on the
+ * incoming queue are waiting for the DMA controller to pick them up and fill
+ * them with data. Block on the outgoing queue have been filled with data and
+ * are waiting for the application to dequeue them and read the data.
+ *
+ * A block can be in one of the following states:
+ * * Owned by the application. In this state the application can read data from
+ * the block.
+ * * On the incoming list: Blocks on the incoming list are queued up to be
+ * processed by the DMA controller.
+ * * Owned by the DMA controller: The DMA controller is processing the block
+ * and filling it with data.
+ * * On the outgoing list: Blocks on the outgoing list have been successfully
+ * processed by the DMA controller and contain data. They can be dequeued by
+ * the application.
+ * * Dead: A block that is dead has been marked as to be freed. It might still
+ * be owned by either the application or the DMA controller at the moment.
+ * But once they are done processing it instead of going to either the
+ * incoming or outgoing queue the block will be freed.
+ *
+ * In addition to this blocks are reference counted and the memory associated
+ * with both the block structure as well as the storage memory for the block
+ * will be freed when the last reference to the block is dropped. This means a
+ * block must not be accessed without holding a reference.
+ *
+ * The iio_dma_buffer implementation provides a generic infrastructure for
+ * managing the blocks.
+ *
+ * A driver for a specific piece of hardware that has DMA capabilities need to
+ * implement the submit() callback from the iio_dma_buffer_ops structure. This
+ * callback is supposed to initiate the DMA transfer copying data from the
+ * converter to the memory region of the block. Once the DMA transfer has been
+ * completed the driver must call iio_dma_buffer_block_done() for the completed
+ * block.
+ *
+ * Prior to this it must set the bytes_used field of the block contains
+ * the actual number of bytes in the buffer. Typically this will be equal to the
+ * size of the block, but if the DMA hardware has certain alignment requirements
+ * for the transfer length it might choose to use less than the full size. In
+ * either case it is expected that bytes_used is a multiple of the bytes per
+ * datum, i.e. the block must not contain partial samples.
+ *
+ * The driver must call iio_dma_buffer_block_done() for each block it has
+ * received through its submit_block() callback, even if it does not actually
+ * perform a DMA transfer for the block, e.g. because the buffer was disabled
+ * before the block transfer was started. In this case it should set bytes_used
+ * to 0.
+ *
+ * In addition it is recommended that a driver implements the abort() callback.
+ * It will be called when the buffer is disabled and can be used to cancel
+ * pending and stop active transfers.
+ *
+ * The specific driver implementation should use the default callback
+ * implementations provided by this module for the iio_buffer_access_funcs
+ * struct. It may overload some callbacks with custom variants if the hardware
+ * has special requirements that are not handled by the generic functions. If a
+ * driver chooses to overload a callback it has to ensure that the generic
+ * callback is called from within the custom callback.

- This option sets IPMMU/IPMMUI address space size by
- adjusting the 1st level page table size. The page table size
- is calculated as follows:
-
- page table size = number of page table entries * 4 bytes
- number of page table entries = address space size / 1 MiB

+ * Transmit half-duplex flow control, under software control for 10/100-Mbps

+ * carrier.
+ * halfdup_retransmit:
+ * Number of retransmission attempts following a collision.
+ * If this is exceeded dTSEC aborts transmission due to excessive collisions.
+ * The standard specifies the attempt limit to be 15.
+ * halfdup_coll_window:
+ * The number of bytes of the frame during which collisions may occur.
+ * The default value of 55 corresponds to the frame byte at the end of the
+ * standard 512-bit slot time window. If collisions are detected after this
+ * byte, the late collision event is asserted and transmission of current
+ * frame is aborted.
+ * tx_pad_crc:
+ * Pad and append CRC. If set, the MAC pads all ransmitted short frames and
+ * appends a CRC to every frame regardless of padding requirement.
+ * tx_pause_time:
+ * Transmit pause time value. This pause value is used as part of the pause
+ * frame to be sent when a transmit pause frame is initiated.
+ * If set to 0 this disables transmission of pause frames.
+ * preamble_len:
+ * Length, in bytes, of the preamble field preceding each Ethernet
+ * start-of-frame delimiter byte. The default value of 0x7 should be used in
+ * order to guarantee reliable operation with IEEE 802.3 compliant hardware.
+ * rx_prepend:
+ * Packet alignment padding length. The specified number of bytes (1-31)
+ * of zero padding are inserted before the start of each received frame.
+ * For Ethernet, where optional preamble extraction is enabled, the padding
+ * appears before the preamble, otherwise the padding precedes the
+ * layer 2 header.
+ *
+ * This structure contains basic dTSEC configuration and must be passed to
+ * init() function. A default set of configuration values can be
+ * obtained by calling set_dflts().
