ACPI and power management updates for 3.15-rc1

Browse Source 
- Device PM QoS support for latency tolerance constraints on systems with
    hardware interfaces allowing such constraints to be specified.  That is
    necessary to prevent hardware-driven power management from becoming
    overly aggressive on some systems and to prevent power management
    features leading to excessive latencies from being used in some cases.
 
  - Consolidation of the handling of ACPI hotplug notifications for device
    objects.  This causes all device hotplug notifications to go through
    the root notify handler (that was executed for all of them anyway
    before) that propagates them to individual subsystems, if necessary,
    by executing callbacks provided by those subsystems (those callbacks
    are associated with struct acpi_device objects during device
    enumeration).  As a result, the code in question becomes both smaller
    in size and more straightforward and all of those changes should not
    affect users.
 
  - ACPICA update, including fixes related to the handling of _PRT in cases
    when it is broken and the addition of "Windows 2013" to the list of
    supported "features" for _OSI (which is necessary to support systems
    that work incorrectly or don't even boot without it).  Changes from
    Bob Moore and Lv Zheng.
 
  - Consolidation of ACPI _OST handling from Jiang Liu.
 
  - ACPI battery and AC fixes allowing unusual system configurations to
    be handled by that code from Alexander Mezin.
 
  - New device IDs for the ACPI LPSS driver from Chiau Ee Chew.
 
  - ACPI fan and thermal optimizations related to system suspend and resume
    from Aaron Lu.
 
  - Cleanups related to ACPI video from Jean Delvare.

Pull ACPI and power management updates from Rafael Wysocki:
 "The majority of this material spent some time in linux-next, some of
  it even several weeks.  There are a few relatively fresh commits in
  it, but they are mostly fixes and simple cleanups.

  ACPI took the lead this time, both in terms of the number of commits
  and the number of modified lines of code, cpufreq follows and there
  are a few changes in the PM core and in cpuidle too.

  A new feature that already got some LWN.net's attention is the device
  PM QoS extension allowing latency tolerance requirements to be
  propagated from leaf devices to their ancestors with hardware
  interfaces for specifying latency tolerance.  That should help systems
  with hardware-driven power management to avoid going too far with it
  in cases when there are latency tolerance constraints.

  There also are some significant changes in the ACPI core related to
  the way in which hotplug notifications are handled.  They affect PCI
  hotplug (ACPIPHP) and the ACPI dock station code too.  The bottom line
  is that all those notification now go through the root notify handler
  and are propagated to the interested subsystems by means of callbacks
  instead of having to install a notify handler for each device object
  that we can potentially get hotplug notifications for.

  In addition to that ACPICA will now advertise "Windows 2013"
  compatibility for _OSI, because some systems out there don't work
  correctly if that is not done (some of them don't even boot).

  On the system suspend side of things, all of the device suspend and
  resume callbacks, except for ->prepare() and ->complete(), are now
  going to be executed asynchronously as that turns out to speed up
  system suspend and resume on some platforms quite significantly and we
  have a few more optimizations in that area.

  Apart from that, there are some new device IDs and fixes and cleanups
  all over.  In particular, the system suspend and resume handling by
  cpufreq should be improved and the cpuidle menu governor should be a
  bit more robust now.

  Specifics:

   - Device PM QoS support for latency tolerance constraints on systems
     with hardware interfaces allowing such constraints to be specified.
     That is necessary to prevent hardware-driven power management from
     becoming overly aggressive on some systems and to prevent power
     management features leading to excessive latencies from being used
     in some cases.

   - Consolidation of the handling of ACPI hotplug notifications for
     device objects.  This causes all device hotplug notifications to go
     through the root notify handler (that was executed for all of them
     anyway before) that propagates them to individual subsystems, if
     necessary, by executing callbacks provided by those subsystems
     (those callbacks are associated with struct acpi_device objects
     during device enumeration).  As a result, the code in question
     becomes both smaller in size and more straightforward and all of
     those changes should not affect users.

   - ACPICA update, including fixes related to the handling of _PRT in
     cases when it is broken and the addition of "Windows 2013" to the

2. PM QoS per-device latency and flags framework
For each device, there are two lists of PM QoS requests. One is maintained
along with the aggregated target of latency value and the other is for PM QoS
flags. Values are updated in response to changes of the request list.
For each device, there are three lists of PM QoS requests. Two of them are
maintained along with the aggregated targets of resume latency and active
state latency tolerance (in microseconds) and the third one is for PM QoS flags.
Values are updated in response to changes of the request list.
Target latency value is simply the minimum of the request values held in the
parameter list elements. The PM QoS flags aggregate value is a gather (bitwise
OR) of all list elements' values. Two device PM QoS flags are defined currently:
PM_QOS_FLAG_NO_POWER_OFF and PM_QOS_FLAG_REMOTE_WAKEUP.

Active state latency tolerance
This device PM QoS type is used to support systems in which hardware may switch
to energy-saving operation modes on the fly. In those systems, if the operation
mode chosen by the hardware attempts to save energy in an overly aggressive way,
it may cause excess latencies to be visible to software, causing it to miss
certain protocol requirements or target frame or sample rates etc.
If there is a latency tolerance control mechanism for a given device available
to software, the .set_latency_tolerance callback in that device's dev_pm_info
structure should be populated. The routine pointed to by it is should implement
whatever is necessary to transfer the effective requirement value to the
hardware.
Whenever the effective latency tolerance changes for the device, its
.set_latency_tolerance() callback will be executed and the effective value will
be passed to it. If that value is negative, which means that the list of
latency tolerance requirements for the device is empty, the callback is expected
to switch the underlying hardware latency tolerance control mechanism to an
autonomous mode if available. If that value is PM_QOS_LATENCY_ANY, in turn, and
the hardware supports a special "no requirement" setting, the callback is
expected to use it. That allows software to prevent the hardware from
automatically updating the device's latency tolerance in response to its power
state changes (e.g. during transitions from D3cold to D0), which generally may
be done in the autonomous latency tolerance control mode.
If .set_latency_tolerance() is present for the device, sysfs attribute
pm_qos_latency_tolerance_us will be present in the devivce's power directory.
Then, user space can use that attribute to specify its latency tolerance
requirement for the device, if any. Writing "any" to it means "no requirement,
but do not let the hardware control latency tolerance" and writing "auto" to it
allows the hardware to be switched to the autonomous mode if there are no other
requirements from the kernel side in the device's list.
Kernel code can use the functions described above along with the
DEV_PM_QOS_LATENCY_TOLERANCE device PM QoS type to add, remove and update
latency tolerance requirements for devices.
