• 2430d12c9   PM: describe kernel policy regarding wakeup defaults (v. 2) ... Browse Code »

  This patch (as1381b) updates a comment describing the kernel's policy
  toward enabling wakeup by default.

  It also makes device_set_wakeup_capable() actually do something when
  CONFIG_PM isn't enabled. It's not clear this is necessary; however if
  it isn't then device_init_wakeup() and device_can_wakeup() should also
  be do-nothing routines. Furthermore, I don't expect this change to
  have any noticeable effect -- but if it does then clearly the old
  behavior was wrong.

  Also change couple of stubs implemented as macros in !CONFIG_PM case
  in statinc inline functions to provide proper typechecking of
  arguments regardless of config.

• c300bd2fb   PCI: include linux/pm_wakeup.h for device_set_wakeup_capable ... Browse Code »

  drivers/pci/pci.c needs pm_wakeup.h since it uses device_set_wakup_capable().
  The latter also needs to be stubbed out for !CONFIG_PM.

• eb9d0fe40   PCI ACPI: Rework PCI handling of wake-up ... Browse Code »

  * Introduce function acpi_pm_device_sleep_wake() for enabling and
  disabling the system wake-up capability of devices that are power
  manageable by ACPI.

  * Introduce function acpi_bus_can_wakeup() allowing other (dependent)
  subsystems to check if ACPI is able to enable the system wake-up
  capability of given device.

  * Introduce callback .sleep_wake() in struct pci_platform_pm_ops and
  for the ACPI PCI 'driver' make it use acpi_pm_device_sleep_wake().

  * Introduce callback .can_wakeup() in struct pci_platform_pm_ops and
  for the ACPI 'driver' make it use acpi_bus_can_wakeup().

  * Move the PME# handlig code out of pci_enable_wake() and split it
  into two functions, pci_pme_capable() and pci_pme_active(),
  allowing the caller to check if given device is capable of
  generating PME# from given power state and to enable/disable the
  device's PME# functionality, respectively.

  * Modify pci_enable_wake() to use the new ACPI callbacks and the new
  PME#-related functions.

  * Drop the generic .platform_enable_wakeup() callback that is not
  used any more.

  * Introduce device_set_wakeup_capable() that will set the
  power.can_wakeup flag of given device.

  * Rework PCI device PM initialization so that, if given device is
  capable of generating wake-up events, either natively through the
  PME# mechanism, or with the help of the platform, its
  power.can_wakeup flag is set and its power.should_wakeup flag is
  unset as appropriate.

  * Make ACPI set the power.can_wakeup flag for devices found to be
  wake-up capable by it.

  * Make the ACPI wake-up code enable/disable GPEs for devices that
  have the wakeup.flags.prepared flag set (which means that their
  wake-up power has been enabled).

• 9a3df1f7d   PM: Convert wakeup flag accessors to inline functions ... Browse Code »

  This patch (as1058) improves the wakeup macros in include/linux/pm.h.
  All but the trivial ones are converted to inline routines, which
  requires moving them to a separate header file since they depend on
  the definition of struct device.
