+Core Scheduling
+===============
+Core scheduling support allows userspace to define groups of tasks that can
+share a core. These groups can be specified either for security usecases (one
+group of tasks don't trust another), or for performance usecases (some
+workloads may benefit from running on the same core as they don't need the same
+hardware resources of the shared core, or may prefer different cores if they
+do share hardware resource needs). This document only describes the security
+usecase.
+
+Security usecase
+----------------
+A cross-HT attack involves the attacker and victim running on different Hyper
+Threads of the same core. MDS and L1TF are examples of such attacks.  The only
+full mitigation of cross-HT attacks is to disable Hyper Threading (HT). Core
+scheduling is a scheduler feature that can mitigate some (not all) cross-HT
+attacks. It allows HT to be turned on safely by ensuring that only tasks in a
+user-designated trusted group can share a core. This increase in core sharing
+can also improve performance, however it is not guaranteed that performance
+will always improve, though that is seen to be the case with a number of real
+world workloads. In theory, core scheduling aims to perform at least as good as
+when Hyper Threading is disabled. In practice, this is mostly the case though
+not always: as synchronizing scheduling decisions across 2 or more CPUs in a
+core involves additional overhead - especially when the system is lightly
+loaded. When ``total_threads <= N_CPUS/2``, the extra overhead may cause core
+scheduling to perform more poorly compared to SMT-disabled, where N_CPUS is the
+total number of CPUs. Please measure the performance of your workloads always.
+
+Usage
+-----
+Core scheduling support is enabled via the ``CONFIG_SCHED_CORE`` config option.
+Using this feature, userspace defines groups of tasks that can be co-scheduled
+on the same core. The core scheduler uses this information to make sure that
+tasks that are not in the same group never run simultaneously on a core, while
+doing its best to satisfy the system's scheduling requirements.
+
+Core scheduling can be enabled via the ``PR_SCHED_CORE`` prctl interface.
+This interface provides support for the creation of core scheduling groups, as
+well as admission and removal of tasks from created groups::
+
+    #include <sys/prctl.h>
+
+    int prctl(int option, unsigned long arg2, unsigned long arg3,
+            unsigned long arg4, unsigned long arg5);
+
+option:
+    ``PR_SCHED_CORE``
+
+arg2:
+    Command for operation, must be one off:
+
+    - ``PR_SCHED_CORE_GET`` -- get core_sched cookie of ``pid``.
+    - ``PR_SCHED_CORE_CREATE`` -- create a new unique cookie for ``pid``.
+    - ``PR_SCHED_CORE_SHARE_TO`` -- push core_sched cookie to ``pid``.
+    - ``PR_SCHED_CORE_SHARE_FROM`` -- pull core_sched cookie from ``pid``.
+
+arg3:
+    ``pid`` of the task for which the operation applies.
+
+arg4:
+    ``pid_type`` for which the operation applies. It is of type ``enum pid_type``.
+    For example, if arg4 is ``PIDTYPE_TGID``, then the operation of this command
+    will be performed for all tasks in the task group of ``pid``.
+
+arg5:
+    userspace pointer to an unsigned long for storing the cookie returned by
+    ``PR_SCHED_CORE_GET`` command. Should be 0 for all other commands.
+
+In order for a process to push a cookie to, or pull a cookie from a process, it
+is required to have the ptrace access mode: `PTRACE_MODE_READ_REALCREDS` to the
+process.
+
+Building hierarchies of tasks
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The simplest way to build hierarchies of threads/processes which share a
+cookie and thus a core is to rely on the fact that the core-sched cookie is
+inherited across forks/clones and execs, thus setting a cookie for the
+'initial' script/executable/daemon will place every spawned child in the
+same core-sched group.
+
+Cookie Transferral
+~~~~~~~~~~~~~~~~~~
+Transferring a cookie between the current and other tasks is possible using
+PR_SCHED_CORE_SHARE_FROM and PR_SCHED_CORE_SHARE_TO to inherit a cookie from a
+specified task or a share a cookie with a task. In combination this allows a
+simple helper program to pull a cookie from a task in an existing core
+scheduling group and share it with already running tasks.
+
+Design/Implementation
+---------------------
+Each task that is tagged is assigned a cookie internally in the kernel. As
+mentioned in `Usage`_, tasks with the same cookie value are assumed to trust
+each other and share a core.
+
+The basic idea is that, every schedule event tries to select tasks for all the
+siblings of a core such that all the selected tasks running on a core are
+trusted (same cookie) at any point in time. Kernel threads are assumed trusted.
+The idle task is considered special, as it trusts everything and everything
+trusts it.
+
+During a schedule() event on any sibling of a core, the highest priority task on
+the sibling's core is picked and assigned to the sibling calling schedule(), if
+the sibling has the task enqueued. For rest of the siblings in the core,
+highest priority task with the same cookie is selected if there is one runnable
+in their individual run queues. If a task with same cookie is not available,
+the idle task is selected.  Idle task is globally trusted.
+
+Once a task has been selected for all the siblings in the core, an IPI is sent to
+siblings for whom a new task was selected. Siblings on receiving the IPI will
+switch to the new task immediately. If an idle task is selected for a sibling,
+then the sibling is considered to be in a `forced idle` state. I.e., it may
+have tasks on its on runqueue to run, however it will still have to run idle.
+More on this in the next section.
+
+Forced-idling of hyperthreads
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The scheduler tries its best to find tasks that trust each other such that all
+tasks selected to be scheduled are of the highest priority in a core.  However,
+it is possible that some runqueues had tasks that were incompatible with the
+highest priority ones in the core. Favoring security over fairness, one or more
+siblings could be forced to select a lower priority task if the highest
+priority task is not trusted with respect to the core wide highest priority
+task.  If a sibling does not have a trusted task to run, it will be forced idle
+by the scheduler (idle thread is scheduled to run).
+
+When the highest priority task is selected to run, a reschedule-IPI is sent to
+the sibling to force it into idle. This results in 4 cases which need to be
+considered depending on whether a VM or a regular usermode process was running
+on either HT::
+
+          HT1 (attack)            HT2 (victim)
+   A      idle -> user space      user space -> idle
+   B      idle -> user space      guest -> idle
+   C      idle -> guest           user space -> idle
+   D      idle -> guest           guest -> idle
+
+Note that for better performance, we do not wait for the destination CPU
+(victim) to enter idle mode. This is because the sending of the IPI would bring
+the destination CPU immediately into kernel mode from user space, or VMEXIT
+in the case of guests. At best, this would only leak some scheduler metadata
+which may not be worth protecting. It is also possible that the IPI is received
+too late on some architectures, but this has not been observed in the case of
+x86.
+
+Trust model
+~~~~~~~~~~~
+Core scheduling maintains trust relationships amongst groups of tasks by
+assigning them a tag that is the same cookie value.
+When a system with core scheduling boots, all tasks are considered to trust
+each other. This is because the core scheduler does not have information about
+trust relationships until userspace uses the above mentioned interfaces, to
+communicate them. In other words, all tasks have a default cookie value of 0.
+and are considered system-wide trusted. The forced-idling of siblings running
+cookie-0 tasks is also avoided.
+
+Once userspace uses the above mentioned interfaces to group sets of tasks, tasks
+within such groups are considered to trust each other, but do not trust those
+outside. Tasks outside the group also don't trust tasks within.
+
+Limitations of core-scheduling
+------------------------------
+Core scheduling tries to guarantee that only trusted tasks run concurrently on a
+core. But there could be small window of time during which untrusted tasks run
+concurrently or kernel could be running concurrently with a task not trusted by
+kernel.
+
+IPI processing delays
+~~~~~~~~~~~~~~~~~~~~~
+Core scheduling selects only trusted tasks to run together. IPI is used to notify
+the siblings to switch to the new task. But there could be hardware delays in
+receiving of the IPI on some arch (on x86, this has not been observed). This may
+cause an attacker task to start running on a CPU before its siblings receive the
+IPI. Even though cache is flushed on entry to user mode, victim tasks on siblings
+may populate data in the cache and micro architectural buffers after the attacker
+starts to run and this is a possibility for data leak.
+
+Open cross-HT issues that core scheduling does not solve
+--------------------------------------------------------
+1. For MDS
+~~~~~~~~~~
+Core scheduling cannot protect against MDS attacks between an HT running in
+user mode and another running in kernel mode. Even though both HTs run tasks
+which trust each other, kernel memory is still considered untrusted. Such
+attacks are possible for any combination of sibling CPU modes (host or guest mode).
+
+2. For L1TF
+~~~~~~~~~~~
+Core scheduling cannot protect against an L1TF guest attacker exploiting a
+guest or host victim. This is because the guest attacker can craft invalid
+PTEs which are not inverted due to a vulnerable guest kernel. The only
+solution is to disable EPT (Extended Page Tables).
+
+For both MDS and L1TF, if the guest vCPU is configured to not trust each
+other (by tagging separately), then the guest to guest attacks would go away.
+Or it could be a system admin policy which considers guest to guest attacks as
+a guest problem.
+
+Another approach to resolve these would be to make every untrusted task on the
+system to not trust every other untrusted task. While this could reduce
+parallelism of the untrusted tasks, it would still solve the above issues while
+allowing system processes (trusted tasks) to share a core.
+
+3. Protecting the kernel (IRQ, syscall, VMEXIT)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Unfortunately, core scheduling does not protect kernel contexts running on
+sibling hyperthreads from one another. Prototypes of mitigations have been posted
+to LKML to solve this, but it is debatable whether such windows are practically
+exploitable, and whether the performance overhead of the prototypes are worth
+it (not to mention, the added code complexity).
+
+Other Use cases
+---------------
+The main use case for Core scheduling is mitigating the cross-HT vulnerabilities
+with SMT enabled. There are other use cases where this feature could be used:
+
+- Isolating tasks that needs a whole core: Examples include realtime tasks, tasks
+  that uses SIMD instructions etc.
+- Gang scheduling: Requirements for a group of tasks that needs to be scheduled
+  together could also be realized using core scheduling. One example is vCPUs of
+  a VM.

-* Renesas Multi Media Card Interface (MMCIF) Controller
-
-This file documents differences between the core properties in mmc.txt
-and the properties used by the MMCIF device.
-
-
-Required properties:
-
-- compatible: should be "renesas,mmcif-<soctype>", "renesas,sh-mmcif" as a
-  fallback. Examples with <soctype> are:
-	- "renesas,mmcif-r7s72100" for the MMCIF found in r7s72100 SoCs
-	- "renesas,mmcif-r8a73a4" for the MMCIF found in r8a73a4 SoCs
-	- "renesas,mmcif-r8a7740" for the MMCIF found in r8a7740 SoCs
-	- "renesas,mmcif-r8a7742" for the MMCIF found in r8a7742 SoCs
-	- "renesas,mmcif-r8a7743" for the MMCIF found in r8a7743 SoCs
-	- "renesas,mmcif-r8a7744" for the MMCIF found in r8a7744 SoCs
-	- "renesas,mmcif-r8a7745" for the MMCIF found in r8a7745 SoCs
-	- "renesas,mmcif-r8a7778" for the MMCIF found in r8a7778 SoCs
-	- "renesas,mmcif-r8a7790" for the MMCIF found in r8a7790 SoCs
-	- "renesas,mmcif-r8a7791" for the MMCIF found in r8a7791 SoCs
-	- "renesas,mmcif-r8a7793" for the MMCIF found in r8a7793 SoCs
-	- "renesas,mmcif-r8a7794" for the MMCIF found in r8a7794 SoCs
-	- "renesas,mmcif-sh73a0" for the MMCIF found in sh73a0 SoCs
-
-- interrupts: Some SoCs have only 1 shared interrupt, while others have either
-  2 or 3 individual interrupts (error, int, card detect). Below is the number
-  of interrupts for each SoC:
-    1: r8a73a4, r8a7742, r8a7743, r8a7744, r8a7745, r8a7778, r8a7790, r8a7791,
-       r8a7793, r8a7794
-    2: r8a7740, sh73a0
-    3: r7s72100
-
-- clocks: reference to the functional clock
-
-- dmas: reference to the DMA channels, one per channel name listed in the
-  dma-names property.
-- dma-names: must contain "tx" for the transmit DMA channel and "rx" for the
-  receive DMA channel.
-- max-frequency: Maximum operating clock frequency, driver uses default clock
-  frequency if it is not set.
-
-
-Example: R8A7790 (R-Car H2) MMCIF0

-		dmas = <&dmac0 0xd1>, <&dmac0 0xd2>;
-		dma-names = "tx", "rx";
-		max-frequency = <97500000>;

+humidity is expressed as a percentage. In sysfs interface, all values are
+scaled by 1000, i.e. the value for 31.5 degrees celsius is 31500.
+
+Usage Notes
+-----------
+
+The device communicates with the I2C protocol. Sensors can have the I2C
+address 0x44. See Documentation/i2c/instantiating-devices.rst for methods
+to instantiate the device.

+Bus lock detection and handling
+===============================
+
+:Copyright: |copy| 2021 Intel Corporation
+:Authors: - Fenghua Yu <fenghua.yu@intel.com>
+          - Tony Luck <tony.luck@intel.com>
+
+Problem
+=======
+
+A split lock is any atomic operation whose operand crosses two cache lines.
+Since the operand spans two cache lines and the operation must be atomic,
+the system locks the bus while the CPU accesses the two cache lines.
+
+A bus lock is acquired through either split locked access to writeback (WB)
+memory or any locked access to non-WB memory. This is typically thousands of
+cycles slower than an atomic operation within a cache line. It also disrupts
+performance on other cores and brings the whole system to its knees.
+
+Detection
+=========
+
+Intel processors may support either or both of the following hardware
+mechanisms to detect split locks and bus locks.
+
+#AC exception for split lock detection
+--------------------------------------
+
+Beginning with the Tremont Atom CPU split lock operations may raise an
+Alignment Check (#AC) exception when a split lock operation is attemped.
+
+#DB exception for bus lock detection
+------------------------------------
+
+Some CPUs have the ability to notify the kernel by an #DB trap after a user
+instruction acquires a bus lock and is executed. This allows the kernel to
+terminate the application or to enforce throttling.
+
+Software handling
+=================
+
+The kernel #AC and #DB handlers handle bus lock based on the kernel
+parameter "split_lock_detect". Here is a summary of different options:
+
++------------------+----------------------------+-----------------------+
+|split_lock_detect=|#AC for split lock		|#DB for bus lock	|
++------------------+----------------------------+-----------------------+
+|off	  	   |Do nothing			|Do nothing		|
++------------------+----------------------------+-----------------------+
+|warn		   |Kernel OOPs			|Warn once per task and |
+|(default)	   |Warn once per task and	|and continues to run.  |
+|		   |disable future checking	|			|
+|		   |When both features are	|			|
+|		   |supported, warn in #AC	|			|
++------------------+----------------------------+-----------------------+
+|fatal		   |Kernel OOPs			|Send SIGBUS to user.	|
+|		   |Send SIGBUS to user		|			|
+|		   |When both features are	|			|
+|		   |supported, fatal in #AC	|			|
++------------------+----------------------------+-----------------------+
+|ratelimit:N	   |Do nothing			|Limit bus lock rate to	|
+|(0 < N <= 1000)   |				|N bus locks per second	|
+|		   |				|system wide and warn on|
+|		   |				|bus locks.		|
++------------------+----------------------------+-----------------------+
+
+Usages
+======
+
+Detecting and handling bus lock may find usages in various areas:
+
+It is critical for real time system designers who build consolidated real
+time systems. These systems run hard real time code on some cores and run
+"untrusted" user processes on other cores. The hard real time cannot afford
+to have any bus lock from the untrusted processes to hurt real time
+performance. To date the designers have been unable to deploy these
+solutions as they have no way to prevent the "untrusted" user code from
+generating split lock and bus lock to block the hard real time code to
+access memory during bus locking.
+
+It's also useful for general computing to prevent guests or user
+applications from slowing down the overall system by executing instructions
+with bus lock.
+
+
+Guidance
+========
+off
+---
+
+Disable checking for split lock and bus lock. This option can be useful if
+there are legacy applications that trigger these events at a low rate so
+that mitigation is not needed.
+
+warn
+----
+
+A warning is emitted when a bus lock is detected which allows to identify
+the offending application. This is the default behavior.
+
+fatal
+-----
+
+In this case, the bus lock is not tolerated and the process is killed.
+
+ratelimit
+---------
+
+A system wide bus lock rate limit N is specified where 0 < N <= 1000. This
+allows a bus lock rate up to N bus locks per second. When the bus lock rate
+is exceeded then any task which is caught via the buslock #DB exception is
+throttled by enforced sleeps until the rate goes under the limit again.
+
+This is an effective mitigation in cases where a minimal impact can be
+tolerated, but an eventual Denial of Service attack has to be prevented. It
+allows to identify the offending processes and analyze whether they are
+malicious or just badly written.
+
+Selecting a rate limit of 1000 allows the bus to be locked for up to about
+seven million cycles each second (assuming 7000 cycles for each bus
+lock). On a 2 GHz processor that would be about 0.35% system slowdown.

-	  Specify the amount of low memory to reserve for the BIOS.
-
-	  The first page contains BIOS data structures that the kernel
-	  must not use, so that page must always be reserved.
-
-	  By default we reserve the first 64K of physical RAM, as a
-	  number of BIOSes are known to corrupt that memory range
-	  during events such as suspend/resume or monitor cable
-	  insertion, so it must not be used by the kernel.
-
-	  You can set this to 4 if you are absolutely sure that you
-	  trust the BIOS to get all its memory reservations and usages
-	  right.  If you know your BIOS have problems beyond the
-	  default 64K area, you can set this to 640 to avoid using the
-	  entire low memory range.
-
-	  If you have doubts about the BIOS (e.g. suspend/resume does
-	  not work or there's kernel crashes after certain hardware
-	  hotplug events) then you might want to enable
-	  X86_CHECK_BIOS_CORRUPTION=y to allow the kernel to check
-	  typical corruption patterns.
-
-	  Leave this to the default value of 64 if you are unsure.

- * ALI M14xx chipset EIDE controller
- *
- * Works for ALI M1439/1443/1445/1487/1489 chipsets.
- *
- * Adapted from code developed by derekn@vw.ece.cmu.edu.  -ml
- * Derek's notes follow:
- *
- * I think the code should be pretty understandable,
- * but I'll be happy to (try to) answer questions.
- *
- * The critical part is in the setupDrive function.  The initRegisters
- * function doesn't seem to be necessary, but the DOS driver does it, so
- * I threw it in.
- *
- * I've only tested this on my system, which only has one disk.  I posted
- * it to comp.sys.linux.hardware, so maybe some other people will try it
- * out.
- *
- * Derek Noonburg  (derekn@ece.cmu.edu)
- * 95-sep-26
- *
- * Update 96-jul-13:
- *
- * I've since upgraded to two disks and a CD-ROM, with no trouble, and
- * I've also heard from several others who have used it successfully.
- * This driver appears to work with both the 1443/1445 and the 1487/1489
- * chipsets.  I've added support for PIO mode 4 for the 1487.  This
- * seems to work just fine on the 1443 also, although I'm not sure it's
- * advertised as supporting mode 4.  (I've been running a WDC AC21200 in
- * mode 4 for a while now with no trouble.)  -Derek

- *
- *  Version 0.97 worked for everybody.
- *

- *  liug@mama.indstate.edu, and others.
- *
- *  Version 0.01	Initial version, hacked out of ide.c,
- *			and #include'd rather than compiled separately.
- *			This will get cleaned up in a subsequent release.
- *
- *  Version 0.02	Fixes for vlb initialization code, enable prefetch
- *			for versions 'B' and 'C' of chip by default,
- *			some code cleanup.
- *
- *  Version 0.03	Added reset of secondary interface,
- *			and black list for devices which are not compatible
- *			with prefetch mode. Separate function for setting
- *			prefetch is added, possibly it will be called some
- *			day from ioctl processing code.
- *
- *  Version 0.04	Now configs/compiles separate from ide.c
- *
- *  Version 0.05	Major rewrite of interface timing code.
- *			Added new function cmd640_set_mode to set PIO mode
- *			from ioctl call. New drives added to black list.
- *
- *  Version 0.06	More code cleanup. Prefetch is enabled only for
- *			detected hard drives, not included in prefetch
- *			black list.
- *
- *  Version 0.07	Changed to more conservative drive tuning policy.
- *			Unknown drives, which report PIO < 4 are set to
- *			(reported_PIO - 1) if it is supported, or to PIO0.
- *			List of known drives extended by info provided by
- *			CMD at their ftp site.
- *
- *  Version 0.08	Added autotune/noautotune support.
- *
- *  Version 0.09	Try to be smarter about 2nd port enabling.
- *  Version 0.10	Be nice and don't reset 2nd port.
- *  Version 0.11	Try to handle more weird situations.
- *
- *  Version 0.12	Lots of bug fixes from Laszlo Peter
- *			irq unmasking disabled for reliability.
- *			try to be even smarter about the second port.
- *			tidy up source code formatting.
- *  Version 0.13	permit irq unmasking again.
- *  Version 0.90	massive code cleanup, some bugs fixed.
- *			defaults all drives to PIO mode0, prefetch off.
- *			autotune is OFF by default, with compile time flag.
- *			prefetch can be turned OFF/ON using "hdparm -p8/-p9"
- *			 (requires hdparm-3.1 or newer)
- *  Version 0.91	first release to linux-kernel list.
- *  Version 0.92	move initial reg dump to separate callable function
- *			change "readahead" to "prefetch" to avoid confusion
- *  Version 0.95	respect original BIOS timings unless autotuning.
- *			tons of code cleanup and rearrangement.
- *			added CONFIG_BLK_DEV_CMD640_ENHANCED option
- *			prevent use of unmask when prefetch is on
- *  Version 0.96	prevent use of io_32bit when prefetch is off
- *  Version 0.97	fix VLB secondary interface for sjd@slip.net
- *			other minor tune-ups:  0.96 was very good.
- *  Version 0.98	ignore PCI version when disabled by BIOS
- *  Version 0.99	display setup/active/recovery clocks with PIO mode
- *  Version 1.00	Mmm.. cannot depend on PCMD_ENA in all systems
- *  Version 1.01	slow/fast devsel can be selected with "hdparm -p6/-p7"
- *			 ("fast" is necessary for 32bit I/O in some systems)
- *  Version 1.02	fix bug that resulted in slow "setup times"

- *	IDE tuning and bus mastering support for the CS5510/CS5520

- *
- *	The practical upshot of this is that we must always tune the

- * From: andy@cercle.cts.com (Dyan Wile)
- *
- * Below is a patch for DTC-2278 - alike software-programmable controllers
- * The code enables the secondary IDE controller and the PIO4 (3?) timings on
- * the primary (EIDE). You may probably have to enable the 32-bit support to
- * get the full speed. You better get the disk interrupts disabled ( hdparm -u0
- * /dev/hd.. ) for the drives connected to the EIDE interface. (I get my
- * filesystem  corrupted with -u1, but under heavy disk load only :-)
- *
- * This card is now forced to use the "serialize" feature,
- * and irq-unmasking is disallowed.  If io_32bit is enabled,
- * it must be done for BOTH drives on each interface.
- *
- * This code was written for the DTC2278E, but might work with any of these:
- *
- * DTC2278S has only a single IDE interface.
- * DTC2278D has two IDE interfaces and is otherwise identical to the S version.
- * DTC2278E also has serial ports and a printer port
- * DTC2278EB: has onboard BIOS, and "works like a charm" -- Kent Bradford <kent@theory.caltech.edu>
- *
- * There may be a fourth controller type. The S and D versions use the
- * Winbond chip, and I think the E version does also.

- * Thanks to HighPoint Technologies for their assistance, and hardware.
- * Special Thanks to Jon Burchmore in SanDiego for the deep pockets, his
- * donation of an ABit BP6 mainboard, processor, and memory acellerated
- * development and support.
- *
- *
- * HighPoint has its own drivers (open source except for the RAID part)
- * available from http://www.highpoint-tech.com/USA_new/service_support.htm 
- * This may be useful to anyone wanting to work on this driver, however  do not
- * trust  them too much since the code tends to become less and less meaningful
- * as the time passes... :-/
- *
- * Note that final HPT370 support was done by force extraction of GPL.
- *
- * - add function for getting/setting power status of drive
- * - the HPT370's state machine can get confused. reset it before each dma 
- *   xfer to prevent that from happening.
- * - reset state engine whenever we get an error.
- * - check for busmaster state at end of dma. 
- * - use new highpoint timings.
- * - detect bus speed using highpoint register.
- * - use pll if we don't have a clock table. added a 66MHz table that's
- *   just 2x the 33MHz table.
- * - removed turnaround. NOTE: we never want to switch between pll and
- *   pci clocks as the chip can glitch in those cases. the highpoint
- *   approved workaround slows everything down too much to be useful. in
- *   addition, we would have to serialize access to each chip.
- * 	Adrian Sun <a.sun@sun.com>
- *
- * add drive timings for 66MHz PCI bus,
- * fix ATA Cable signal detection, fix incorrect /proc info
- * add /proc display for per-drive PIO/DMA/UDMA mode and
- * per-channel ATA-33/66 Cable detect.
- * 	Duncan Laurie <void@sun.com>
- *
- * fixup /proc output for multiple controllers
- *	Tim Hockin <thockin@sun.com>
- *
- * On hpt366: 
- * Reset the hpt366 on error, reset on dma
- * Fix disabling Fast Interrupt hpt366.
- * 	Mike Waychison <crlf@sun.com>
- *
- * Added support for 372N clocking and clock switching. The 372N needs
- * different clocks on read/write. This requires overloading rw_disk and
- * other deeply crazy things. Thanks to <http://www.hoerstreich.de> for
- * keeping me sane. 
- *		Alan Cox <alan@lxorguk.ukuu.org.uk>
- *
- * - fix the clock turnaround code: it was writing to the wrong ports when
- *   called for the secondary channel, caching the current clock mode per-
- *   channel caused the cached register value to get out of sync with the
- *   actual one, the channels weren't serialized, the turnaround shouldn't
- *   be done on 66 MHz PCI bus
- * - disable UltraATA/100 for HPT370 by default as the 33 MHz clock being used
- *   does not allow for this speed anyway
- * - avoid touching disabled channels (e.g. HPT371/N are single channel chips,
- *   their primary channel is kind of virtual, it isn't tied to any pins)
- * - fix/remove bad/unused timing tables and use one set of tables for the whole
- *   HPT37x chip family; save space by introducing the separate transfer mode
- *   table in which the mode lookup is done
- * - use f_CNT value saved by  the HighPoint BIOS as reading it directly gives
- *   the wrong PCI frequency since DPLL has already been calibrated by BIOS;
- *   read it only from the function 0 of HPT374 chips
- * - fix the hotswap code:  it caused RESET- to glitch when tristating the bus,
- *   and for HPT36x the obsolete HDIO_TRISTATE_HWIF handler was called instead
- * - pass to init_chipset() handlers a copy of the IDE PCI device structure as
- *   they tamper with its fields
- * - pass  to the init_setup handlers a copy of the ide_pci_device_t structure
- *   since they may tamper with its fields
- * - prefix the driver startup messages with the real chip name
- * - claim the extra 240 bytes of I/O space for all chips
- * - optimize the UltraDMA filtering and the drive list lookup code
- * - use pci_get_slot() to get to the function 1 of HPT36x/374
- * - cache offset of the channel's misc. control registers (MCRs) being used
- *   throughout the driver
- * - only touch the relevant MCR when detecting the cable type on HPT374's
- *   function 1
- * - rename all the register related variables consistently
- * - move all the interrupt twiddling code from the speedproc handlers into
- *   init_hwif_hpt366(), also grouping all the DMA related code together there
- * - merge HPT36x/HPT37x speedproc handlers, fix PIO timing register mask and
- *   separate the UltraDMA and MWDMA masks there to avoid changing PIO timings
- *   when setting an UltraDMA mode
- * - fix hpt3xx_tune_drive() to set the PIO mode requested, not always select
- *   the best possible one
- * - clean up DMA timeout handling for HPT370
- * - switch to using the enumeration type to differ between the numerous chip
- *   variants, matching PCI device/revision ID with the chip type early, at the
- *   init_setup stage
- * - extend the hpt_info structure to hold the DPLL and PCI clock frequencies,
- *   stop duplicating it for each channel by storing the pointer in the pci_dev
- *   structure: first, at the init_setup stage, point it to a static "template"
- *   with only the chip type and its specific base DPLL frequency, the highest
- *   UltraDMA mode, and the chip settings table pointer filled,  then, at the
- *   init_chipset stage, allocate per-chip instance  and fill it with the rest
- *   of the necessary information
- * - get rid of the constant thresholds in the HPT37x PCI clock detection code,
- *   switch  to calculating  PCI clock frequency based on the chip's base DPLL
- *   frequency
- * - switch to using the  DPLL clock and enable UltraATA/133 mode by default on
- *   anything  newer than HPT370/A (except HPT374 that is not capable of this
- *   mode according to the manual)
- * - fold PCI clock detection and DPLL setup code into init_chipset_hpt366(),
- *   also fixing the interchanged 25/40 MHz PCI clock cases for HPT36x chips;
- *   unify HPT36x/37x timing setup code and the speedproc handlers by joining
- *   the register setting lists into the table indexed by the clock selected
- * - set the correct hwif->ultra_mask for each individual chip
- * - add Ultra and MW DMA mode filtering for the HPT37[24] based SATA cards
- * - stop resetting HPT370's state machine before each DMA transfer as that has
- *   caused more harm than good

- * ht6560b Timing values:
- *
- * I reviewed some assembler source listings of htide drivers and found
- * out how they setup those cycle time interfacing values, as they at Holtek
- * call them. IDESETUP.COM that is supplied with the drivers figures out
- * optimal values and fetches those values to drivers. I found out that
- * they use Select register to fetch timings to the ide board right after
- * interface switching. After that it was quite easy to add code to
- * ht6560b.c.
- *
- * IDESETUP.COM gave me values 0x24, 0x45, 0xaa, 0xff that worked fine
- * for hda and hdc. But hdb needed higher values to work, so I guess
- * that sometimes it is necessary to give higher value than IDESETUP
- * gives.   [see cmd640.c for an extreme example of this. -ml]
- *
- * Perhaps I should explain something about these timing values:
- * The higher nibble of value is the Recovery Time  (rt) and the lower nibble
- * of the value is the Active Time  (at). Minimum value 2 is the fastest and
- * the maximum value 15 is the slowest. Default values should be 15 for both.
- * So 0x24 means 2 for rt and 4 for at. Each of the drives should have
- * both values, and IDESETUP gives automatically rt=15 st=15 for CDROMs or
- * similar. If value is too small there will be all sorts of failures.
- *
- * Timing byte consists of
- *	High nibble:  Recovery Cycle Time  (rt)
- *	     The valid values range from 2 to 15. The default is 15.
- *
- *	Low nibble:   Active Cycle Time	   (at)
- *	     The valid values range from 2 to 15. The default is 15.
- *
- * You can obtain optimized timing values by running Holtek IDESETUP.COM
- * for DOS. DOS drivers get their timing values from command line, where
- * the first value is the Recovery Time and the second value is the
- * Active Time for each drive. Smaller value gives higher speed.
- * In case of failures you should probably fall back to a higher value.

- *	There should be no way that an irq can happen before we're ready for it,
- *	so we needn't worry much about losing an "important" interrupt here.
- *
- *	On laptops (and "green" PCs), an unexpected interrupt occurs whenever

- *	looks "good", we just ignore the interrupt completely.
- *
- *	This routine assumes __cli() is in effect when called.
- *
- *	If an unexpected interrupt happens on irq15 while we are handling irq14
- *	and if the two interfaces are "serialized" (CMD640), then it looks like
- *	we could screw up by interfering with a new request being set up for 
- *	irq15.
- *
- *	In reality, this is a non-issue.  The new command is not sent unless 
- *	the drive is ready to accept one, in which case we know the drive is
- *	not trying to interrupt us.  And ide_set_handler() is always invoked
- *	before completing the issuance of any new drive command, so we will not

- * Polling for DSC (a single bit in the status register) is a very important

- *
- * 1. Before a read/write packet command, to ensure that we can transfer data
- * from/to the tape's data buffers, without causing an actual media access.
- * In case the tape is not ready yet, we take out our request from the device
- * request queue, so that ide.c could service requests from the other device
- * on the same interface in the meantime.
- *
- * 2. After the successful initialization of a "media access packet command",
- * which is a command that can take a long time to complete (the interval can
- * range from several seconds to even an hour). Again, we postpone our request
- * in the middle to free the bus for the other device. The polling frequency
- * here should be lower than the read/write frequency since those media access
- * commands are slow. We start from a "fast" frequency - IDETAPE_DSC_MA_FAST
- * (1 second), and if we don't receive DSC after IDETAPE_DSC_MA_THRESHOLD
- * (5 min), we switch it to a lower frequency - IDETAPE_DSC_MA_SLOW (1 min).
- *
- * We also set a timeout for the timer, in case something goes wrong. The
- * timeout should be longer then the maximum execution time of a tape operation.

- * Packet Command Interface
- *
- * The current Packet Command is available in drive->pc, and will not change
- * until we finish handling it. Each packet command is associated with a
- * callback function that will be called when the command is finished.
- *
- * The handling will be done in three stages:
- *
- * 1. ide_tape_issue_pc will send the packet command to the drive, and will set
- * the interrupt handler to ide_pc_intr.
- *
- * 2. On each interrupt, ide_pc_intr will be called. This step will be
- * repeated until the device signals us that no more interrupts will be issued.
- *
- * 3. ATAPI Tape media access commands have immediate status with a delayed
- * process. In case of a successful initiation of a media access packet command,
- * the DSC bit will be set when the actual execution of the command is finished.
- * Since the tape drive will not issue an interrupt, we have to poll for this
- * event. In this case, we define the request as "low priority request" by
- * setting rq_status to IDETAPE_RQ_POSTPONED, set a timer to poll for DSC and
- * exit the driver.
- *
- * ide.c will then give higher priority to requests which originate from the
- * other device, until will change rq_status to RQ_ACTIVE.
- *
- * 4. When the packet command is finished, it will be checked for errors.
- *
- * 5. In case an error was found, we queue a request sense packet command in
- * front of the request queue and retry the operation up to
- * IDETAPE_MAX_PC_RETRIES times.
- *
- * 6. In case no error was found, or we decided to give up and not to retry
- * again, the callback function will be called and then we will handle the next
- * request.

- *

- *  Documentation:
- *	Datasheet is freely available, some other documents under NDA.
- *
- *  The ITE8212 isn't exactly a standard IDE controller. It has two
- *  modes. In pass through mode then it is an IDE controller. In its smart
- *  mode its actually quite a capable hardware raid controller disguised
- *  as an IDE controller. Smart mode only understands DMA read/write and
- *  identify, none of the fancier commands apply. The IT8211 is identical
- *  in other respects but lacks the raid mode.
- *
- *  Errata:
- *  o	Rev 0x10 also requires master/slave hold the same DMA timings and
- *	cannot do ATAPI MWDMA.
- *  o	The identify data for raid volumes lacks CHS info (technically ok)
- *	but also fails to set the LBA28 and other bits. We fix these in
- *	the IDE probe quirk code.
- *  o	If you write LBA48 sized I/O's (ie > 256 sector) in smart mode
- *	raid then the controller firmware dies
- *  o	Smart mode without RAID doesn't clear all the necessary identify
- *	bits to reduce the command set to the one used
- *
- *  This has a few impacts on the driver
- *  - In pass through mode we do all the work you would expect
- *  - In smart mode the clocking set up is done by the controller generally
- *    but we must watch the other limits and filter.
- *  - There are a few extra vendor commands that actually talk to the
- *    controller but only work PIO with no IRQ.
- *
- *  Vendor areas of the identify block in smart mode are used for the
- *  timing and policy set up. Each HDD in raid mode also has a serial
- *  block on the disk. The hardware extra commands are get/set chip status,
- *  rebuild, get rebuild status.
- *
- *  In Linux the driver supports pass through mode as if the device was
- *  just another IDE controller. If the smart mode is running then
- *  volumes are managed by the controller firmware and each IDE "disk"
- *  is a raid volume. Even more cute - the controller can do automated
- *  hotplug and rebuild.
- *
- *  The pass through controller itself is a little demented. It has a
- *  flaw that it has a single set of PIO/MWDMA timings per channel so
- *  non UDMA devices restrict each others performance. It also has a
- *  single clock source per channel so mixed UDMA100/133 performance
- *  isn't perfect and we have to pick a clock. Thankfully none of this
- *  matters in smart mode. ATAPI DMA is not currently supported.
- *
- *  It seems the smart mode is a win for RAID1/RAID10 but otherwise not.
- *
- *  TODO
- *	-	ATAPI UDMA is ok but not MWDMA it seems
- *	-	RAID configuration ioctls
- *	-	Move to libata once it grows up

- * PIIX4. Older device documentation is now a bit tricky to find.
- *
- * Errata of note:
- *
- * Unfixable
- *	PIIX4    errata #9	- Only on ultra obscure hw
- *	ICH3	 errata #13     - Not observed to affect real hw
- *				  by Intel
- *
- * Things we must deal with
- *	PIIX4	errata #10	- BM IDE hang with non UDMA
- *				  (must stop/start dma to recover)
- *	440MX   errata #15	- As PIIX4 errata #10
- *	PIIX4	errata #15	- Must not read control registers
- * 				  during a PIO transfer
- *	440MX   errata #13	- As PIIX4 errata #15
- *	ICH2	errata #21	- DMA mode 0 doesn't work right
- *	ICH0/1  errata #55	- As ICH2 errata #21
- *	ICH2	spec c #9	- Extra operations needed to handle
- *				  drive hotswap [NOT YET SUPPORTED]
- *	ICH2    spec c #20	- IDE PRD must not cross a 64K boundary
- *				  and must be dword aligned
- *	ICH2    spec c #24	- UDMA mode 4,5 t85/86 should be 6ns not 3.3
- *
- * Should have been BIOS fixed:
- *	450NX:	errata #19	- DMA hangs on old 450NX
- *	450NX:  errata #20	- DMA hangs on old 450NX
- *	450NX:  errata #25	- Corruption with DMA on old 450NX
- *	ICH3    errata #15      - IDE deadlock under high load
- *				  (BIOS must set dev 31 fn 0 bit 23)
- *	ICH3	errata #18	- Don't use native mode

- *	If you have strange problems with nVidia chipset systems please

- * The original SiS5513 comes from a SiS5511/55112/5513 chipset. The original

- * or SiS5596, we can assume we see the first MWDMA-16 capable SiS5513 chip.
- *
- * Later SiS chipsets integrated the 5513 functionality into the NorthBridge,
- * starting with SiS5571 and up to SiS745. The PCI ID didn't change, though. We
- * can figure out that we have a more modern and more capable 5513 by looking
- * for the respective NorthBridge IDs.
- *
- * Even later (96x family) SiS chipsets use the MuTIOL link and place the 5513
- * into the SouthBrige. Here we cannot rely on looking up the NorthBridge PCI
- * ID, while the now ATA-133 capable 5513 still has the same PCI ID.
- * Fortunately the 5513 can be 'unmasked' by fiddling with some config space
- * bits, changing its device id to the true one - 5517 for 961 and 5518 for
- * 962/963.

+ * @skip_off:	If set to true the IRQ handler will attempt to check if any of

+ *		fail fatal_cnt times this callback or BUG() is called. This

+ *		disabling the regulator. If protection succeeded this may
+ *		return 0. If anything else is returned the core assumes final
+ *		protection failed and calls BUG() as a last resort.
+ * @map_event:	Driver callback to map IRQ status into regulator devices with
+ *		events / errors. NOTE: callback MUST initialize both the
+ *		errors and notifs for all rdevs which it signals having
+ *		active events as core does not clean the map data.
+ *		REGULATOR_FAILED_RETRY can be returned to indicate that the
+ *		status reading from IC failed. If this is repeated for
+ *		fatal_cnt times the core will call die() callback or BUG()
+ *		as a last resort to protect the HW.
+ * @renable:	Optional callback to check status (if HW supports that) before
+ *		re-enabling IRQ. If implemented this should clear the error
+ *		flags so that errors fetched by regulator_get_error_flags()
+ *		are updated. If callback is not implemented then errors are
+ *		assumed to be cleared and IRQ is re-enabled.
+ *		REGULATOR_FAILED_RETRY can be returned to
+ *		indicate that the status reading from IC failed. If this is
+ *		repeated for 'fatal_cnt' times the core will call die()
+ *		callback or BUG() as a last resort to protect the HW.
+ *		Returning zero indicates that the problem in HW has been solved
+ *		and IRQ will be re-enabled. Returning REGULATOR_ERROR_ON
+ *		indicates the error condition is still active and keeps IRQ
+ *		disabled. Please note that returning REGULATOR_ERROR_ON does
+ *		not retrigger evaluating what events are active or resending

+ * After BFS we get a lock dependency path (linked via ->parent of lock_list),
+ * printing out each lock in the dependency path will help on understanding how
+ * the deadlock could happen. Here are some details about dependency path
+ * printing:
+ *
+ * 1)	A lock_list can be either forwards or backwards for a lock dependency,
+ * 	for a lock dependency A -> B, there are two lock_lists:
+ *
+ * 	a)	lock_list in the ->locks_after list of A, whose ->class is B and
+ * 		->links_to is A. In this case, we can say the lock_list is
+ * 		"A -> B" (forwards case).
+ *
+ * 	b)	lock_list in the ->locks_before list of B, whose ->class is A
+ * 		and ->links_to is B. In this case, we can say the lock_list is
+ * 		"B <- A" (bacwards case).
+ *
+ * 	The ->trace of both a) and b) point to the call trace where B was
+ * 	acquired with A held.
+ *
+ * 2)	A "helper" lock_list is introduced during BFS, this lock_list doesn't
+ * 	represent a certain lock dependency, it only provides an initial entry
+ * 	for BFS. For example, BFS may introduce a "helper" lock_list whose
+ * 	->class is A, as a result BFS will search all dependencies starting with
+ * 	A, e.g. A -> B or A -> C.
+ *
+ * 	The notation of a forwards helper lock_list is like "-> A", which means
+ * 	we should search the forwards dependencies starting with "A", e.g A -> B
+ * 	or A -> C.
+ *
+ * 	The notation of a bacwards helper lock_list is like "<- B", which means
+ * 	we should search the backwards dependencies ending with "B", e.g.
+ * 	B <- A or B <- C.
