+ * Dynamic queue limits (dql) - Definitions
+ *
+ * Copyright (c) 2011, Tom Herbert <therbert@google.com>
+ *
+ * This header file contains the definitions for dynamic queue limits (dql).
+ * dql would be used in conjunction with a producer/consumer type queue
+ * (possibly a HW queue).  Such a queue would have these general properties:
+ *
+ *   1) Objects are queued up to some limit specified as number of objects.
+ *   2) Periodically a completion process executes which retires consumed
+ *      objects.
+ *   3) Starvation occurs when limit has been reached, all queued data has
+ *      actually been consumed, but completion processing has not yet run
+ *      so queuing new data is blocked.
+ *   4) Minimizing the amount of queued data is desirable.
+ *
+ * The goal of dql is to calculate the limit as the minimum number of objects
+ * needed to prevent starvation.
+ *
+ * The primary functions of dql are:
+ *    dql_queued - called when objects are enqueued to record number of objects
+ *    dql_avail - returns how many objects are available to be queued based
+ *      on the object limit and how many objects are already enqueued
+ *    dql_completed - called at completion time to indicate how many objects
+ *      were retired from the queue
+ *
+ * The dql implementation does not implement any locking for the dql data
+ * structures, the higher layer should provide this.  dql_queued should
+ * be serialized to prevent concurrent execution of the function; this
+ * is also true for  dql_completed.  However, dql_queued and dlq_completed  can
+ * be executed concurrently (i.e. they can be protected by different locks).

+ * @NL80211_CMD_UNEXPECTED_FRAME: Used by an application controlling an AP
+ *      (or GO) interface (i.e. hostapd) to ask for unexpected frames to
+ *      implement sending deauth to stations that send unexpected class 3
+ *      frames. Also used as the event sent by the kernel when such a frame
+ *      is received.
+ *      For the event, the %NL80211_ATTR_MAC attribute carries the TA and
+ *      other attributes like the interface index are present.
+ *      If used as the command it must have an interface index and you can
+ *      only unsubscribe from the event by closing the socket. Subscription
+ *      is also for %NL80211_CMD_UNEXPECTED_4ADDR_FRAME events.
+ *
+ * @NL80211_CMD_UNEXPECTED_4ADDR_FRAME: Sent as an event indicating that the
+ *      associated station identified by %NL80211_ATTR_MAC sent a 4addr frame

+ *      acknowleged. This is used to allow timing out inactive clients. Uses
+ *      %NL80211_ATTR_IFINDEX and %NL80211_ATTR_MAC. The command returns a

+ * @NL80211_CMD_REGISTER_BEACONS: Register this socket to receive beacons from

+ * internal transitions to various low-power modes which are transparent
  * to the rest of the driver stack (such as a driver that's ON gating off

  *
- * The externally visible transitions are handled with the help of the following
- * callbacks included in this structure:
- *
- * @prepare: Prepare the device for the upcoming transition, but do NOT change
- *      its hardware state.  Prevent new children of the device from being
- *      registered after @prepare() returns (the driver's subsystem and
- *      generally the rest of the kernel is supposed to prevent new calls to the
- *      probe method from being made too once @prepare() has succeeded).  If
- *      @prepare() detects a situation it cannot handle (e.g. registration of a
- *      child already in progress), it may return -EAGAIN, so that the PM core
- *      can execute it once again (e.g. after the new child has been registered)
- *      to recover from the race condition.  This method is executed for all
- *      kinds of suspend transitions and is followed by one of the suspend
- *      callbacks: @suspend(), @freeze(), or @poweroff().
- *      The PM core executes @prepare() for all devices before starting to
- *      execute suspend callbacks for any of them, so drivers may assume all of
- *      the other devices to be present and functional while @prepare() is being
- *      executed.  In particular, it is safe to make GFP_KERNEL memory
- *      allocations from within @prepare().  However, drivers may NOT assume
- *      anything about the availability of the user space at that time and it
- *      is not correct to request firmware from within @prepare() (it's too
- *      late to do that).  [To work around this limitation, drivers may
- *      register suspend and hibernation notifiers that are executed before the
- *      freezing of tasks.]
+ * The externally visible transitions are handled with the help of callbacks
+ * included in this structure in such a way that two levels of callbacks are
+ * involved.  First, the PM core executes callbacks provided by PM domains,
+ * device types, classes and bus types.  They are the subsystem-level callbacks
+ * supposed to execute callbacks provided by device drivers, although they may
+ * choose not to do that.  If the driver callbacks are executed, they have to
+ * collaborate with the subsystem-level callbacks to achieve the goals
+ * appropriate for the given system transition, given transition phase and the
+ * subsystem the device belongs to.
+ *
+ * @prepare: The principal role of this callback is to prevent new children of
+ *      the device from being registered after it has returned (the driver's
+ *      subsystem and generally the rest of the kernel is supposed to prevent
+ *      new calls to the probe method from being made too once @prepare() has
+ *      succeeded).  If @prepare() detects a situation it cannot handle (e.g.
+ *      registration of a child already in progress), it may return -EAGAIN, so
+ *      that the PM core can execute it once again (e.g. after a new child has
+ *      been registered) to recover from the race condition.
+ *      This method is executed for all kinds of suspend transitions and is
+ *      followed by one of the suspend callbacks: @suspend(), @freeze(), or
+ *      @poweroff().  The PM core executes subsystem-level @prepare() for all
+ *      devices before starting to invoke suspend callbacks for any of them, so
+ *      generally devices may be assumed to be functional or to respond to
+ *      runtime resume requests while @prepare() is being executed.  However,
+ *      device drivers may NOT assume anything about the availability of user
+ *      space at that time and it is NOT valid to request firmware from within
+ *      @prepare() (it's too late to do that).  It also is NOT valid to allocate
+ *      substantial amounts of memory from @prepare() in the GFP_KERNEL mode.
+ *      [To work around these limitations, drivers may register suspend and
+ *      hibernation notifiers to be executed before the freezing of tasks.]
  *
  * @complete: Undo the changes made by @prepare().  This method is executed for
  *      all kinds of resume transitions, following one of the resume callbacks:
  *      @resume(), @thaw(), @restore().  Also called if the state transition
- *      fails before the driver's suspend callback (@suspend(), @freeze(),
- *      @poweroff()) can be executed (e.g. if the suspend callback fails for one
+ *      fails before the driver's suspend callback: @suspend(), @freeze() or
+ *      @poweroff(), can be executed (e.g. if the suspend callback fails for one
  *      of the other devices that the PM core has unsuccessfully attempted to
  *      suspend earlier).
- *      The PM core executes @complete() after it has executed the appropriate
- *      resume callback for all devices.
+ *      The PM core executes subsystem-level @complete() after it has executed
+ *      the appropriate resume callbacks for all devices.
  *
  * @suspend: Executed before putting the system into a sleep state in which the
- *      contents of main memory are preserved.  Quiesce the device, put it into
- *      a low power state appropriate for the upcoming system state (such as
- *      PCI_D3hot), and enable wakeup events as appropriate.
+ *      contents of main memory are preserved.  The exact action to perform
+ *      depends on the device's subsystem (PM domain, device type, class or bus
+ *      type), but generally the device must be quiescent after subsystem-level
+ *      @suspend() has returned, so that it doesn't do any I/O or DMA.
+ *      Subsystem-level @suspend() is executed for all devices after invoking
+ *      subsystem-level @prepare() for all of them.
  *
  * @resume: Executed after waking the system up from a sleep state in which the
- *      contents of main memory were preserved.  Put the device into the
- *      appropriate state, according to the information saved in memory by the
- *      preceding @suspend().  The driver starts working again, responding to
- *      hardware events and software requests.  The hardware may have gone
- *      through a power-off reset, or it may have maintained state from the
- *      previous suspend() which the driver may rely on while resuming.  On most
- *      platforms, there are no restrictions on availability of resources like
- *      clocks during @resume().
+ *      contents of main memory were preserved.  The exact action to perform
+ *      depends on the device's subsystem, but generally the driver is expected
+ *      to start working again, responding to hardware events and software
+ *      requests (the device itself may be left in a low-power state, waiting
+ *      for a runtime resume to occur).  The state of the device at the time its
+ *      driver's @resume() callback is run depends on the platform and subsystem
+ *      the device belongs to.  On most platforms, there are no restrictions on
+ *      availability of resources like clocks during @resume().
+ *      Subsystem-level @resume() is executed for all devices after invoking
+ *      subsystem-level @resume_noirq() for all of them.
  *
  * @freeze: Hibernation-specific, executed before creating a hibernation image.
- *      Quiesce operations so that a consistent image can be created, but do NOT
- *      otherwise put the device into a low power device state and do NOT emit
- *      system wakeup events.  Save in main memory the device settings to be
- *      used by @restore() during the subsequent resume from hibernation or by
- *      the subsequent @thaw(), if the creation of the image or the restoration
- *      of main memory contents from it fails.
+ *      Analogous to @suspend(), but it should not enable the device to signal
+ *      wakeup events or change its power state.  The majority of subsystems
+ *      (with the notable exception of the PCI bus type) expect the driver-level
+ *      @freeze() to save the device settings in memory to be used by @restore()
+ *      during the subsequent resume from hibernation.
+ *      Subsystem-level @freeze() is executed for all devices after invoking
+ *      subsystem-level @prepare() for all of them.
  *
  * @thaw: Hibernation-specific, executed after creating a hibernation image OR
- *      if the creation of the image fails.  Also executed after a failing
+ *      if the creation of an image has failed.  Also executed after a failing
  *      attempt to restore the contents of main memory from such an image.
  *      Undo the changes made by the preceding @freeze(), so the device can be
  *      operated in the same way as immediately before the call to @freeze().
+ *      Subsystem-level @thaw() is executed for all devices after invoking
+ *      subsystem-level @thaw_noirq() for all of them.  It also may be executed
+ *      directly after @freeze() in case of a transition error.
  *
  * @poweroff: Hibernation-specific, executed after saving a hibernation image.
- *      Quiesce the device, put it into a low power state appropriate for the
- *      upcoming system state (such as PCI_D3hot), and enable wakeup events as
- *      appropriate.
+ *      Analogous to @suspend(), but it need not save the device's settings in
+ *      memory.
+ *      Subsystem-level @poweroff() is executed for all devices after invoking
+ *      subsystem-level @prepare() for all of them.
  *
  * @restore: Hibernation-specific, executed after restoring the contents of main
- *      memory from a hibernation image.  Driver starts working again,
- *      responding to hardware events and software requests.  Drivers may NOT
- *      make ANY assumptions about the hardware state right prior to @restore().
- *      On most platforms, there are no restrictions on availability of
- *      resources like clocks during @restore().
- *
- * @suspend_noirq: Complete the operations of ->suspend() by carrying out any
- *      actions required for suspending the device that need interrupts to be
- *      disabled
- *
- * @resume_noirq: Prepare for the execution of ->resume() by carrying out any
- *      actions required for resuming the device that need interrupts to be
- *      disabled
- *
- * @freeze_noirq: Complete the operations of ->freeze() by carrying out any
- *      actions required for freezing the device that need interrupts to be
- *      disabled

- * @thaw_noirq: Prepare for the execution of ->thaw() by carrying out any
- *      actions required for thawing the device that need interrupts to be
- *      disabled
- *
- * @poweroff_noirq: Complete the operations of ->poweroff() by carrying out any
- *      actions required for handling the device that need interrupts to be
- *      disabled
- *
- * @restore_noirq: Prepare for the execution of ->restore() by carrying out any
- *      actions required for restoring the operations of the device that need
- *      interrupts to be disabled
+ *      memory from a hibernation image, analogous to @resume().
+ *
+ * @suspend_noirq: Complete the actions started by @suspend().  Carry out any
+ *      additional operations required for suspending the device that might be
+ *      racing with its driver's interrupt handler, which is guaranteed not to
+ *      run while @suspend_noirq() is being executed.
+ *      It generally is expected that the device will be in a low-power state
+ *      (appropriate for the target system sleep state) after subsystem-level
+ *      @suspend_noirq() has returned successfully.  If the device can generate
+ *      system wakeup signals and is enabled to wake up the system, it should be
+ *      configured to do so at that time.  However, depending on the platform
+ *      and device's subsystem, @suspend() may be allowed to put the device into
+ *      the low-power state and configure it to generate wakeup signals, in
+ *      which case it generally is not necessary to define @suspend_noirq().
+ *
+ * @resume_noirq: Prepare for the execution of @resume() by carrying out any
+ *      operations required for resuming the device that might be racing with
+ *      its driver's interrupt handler, which is guaranteed not to run while
+ *      @resume_noirq() is being executed.

+ * @freeze_noirq: Complete the actions started by @freeze().  Carry out any
+ *      additional operations required for freezing the device that might be
+ *      racing with its driver's interrupt handler, which is guaranteed not to
+ *      run while @freeze_noirq() is being executed.
+ *      The power state of the device should not be changed by either @freeze()
+ *      or @freeze_noirq() and it should not be configured to signal system
+ *      wakeup by any of these callbacks.
+ *
+ * @thaw_noirq: Prepare for the execution of @thaw() by carrying out any
+ *      operations required for thawing the device that might be racing with its
