• cbbc0de70   ACPI: Use GPE reference counting to support shared GPEs ... Browse Code »

  To fix a bug and address the reviewers' comments regarding the ACPI
  GPE refcounting patch, do the following additional changes:

  o Remove the second argument of acpi_ev_enable_gpe(),
  'write_to_hardware', because it is not necessary any more.

  o Add the "bad parameter" test against 'type' in
  acpi_enable_gpe() and acpi_disable_gpe().

  o Make acpi_enable_gpe() only check 'status' for runtime GPEs if
  acpi_ev_enable_gpe() was actually called.

  o Make acpi_disable_gpe() return 'status' returned by
  acpi_ev_disable_gpe() and fix a bug where ACPI_GPE_TYPE_WAKE
  and ACPI_GPE_TYPE_RUNTIME were exchanged by mistake.

  o Add comments explaining why acpi_set_gpe() is used by the ACPI EC
  driver.

  ACPI GPEs may map to multiple devices. The current GPE interface
  only provides a mechanism for enabling and disabling GPEs, making
  it difficult to change the state of GPEs at runtime without extensive
  cooperation between devices.

  Add an API to allow devices to indicate whether or not they want
  their device's GPE to be enabled for both runtime and wakeup events.

  Remove the old GPE type handling entirely, which gets rid of various
  quirks, like the implicit disabling with GPE type setting. This
  requires a small amount of rework in order to ensure that non-wake
  GPEs are enabled by default to preserve existing behaviour.

  Based on patches from Matthew Garrett .

• c6b5774ca   ACPICA: Add 64-bit support to acpi_read and acpi_write ... Browse Code »

  Needed by drivers for new ACPi tables. Internal versions of
  these functions still use 32-bit max transfers, in order to
  minimize disruption and stack use for the standard ACPI registers
  (FADT-based).
