Subject: [PATCH v2 0/7] ACPI: Add _OST support for ACPI hotplug
Date: Tue, 8 May 2012 14:12:17 -0600 [thread overview]
Message-ID: <1336507944-10219-1-git-send-email-toshi.kani@hp.com> (raw)
This patchset supports ACPI OSPM Status Indication (_OST) method for
ACPI CPU/memory/container hotplug operations and sysfs eject. After
ACPI hotplug operation has completed, OSPM calls _OST to indicate the
status of the operation to the platform. If _OST is not present, this
patchset has no effect on the platform.
This _OST support can be enabled or disabled with a new config option
CONFIG_ACPI_HOTPLUG_OST. This option is disabled by default. When
this option is disabled, this patchset has no effect on the platform.
The _OST definition can be found in section 6.3.5 of ACPI 5.0 spec.
The HPPF spec below also describes hotplug flows with _OST.
DIG64 Hot-Plug & Partitioning Flow (HPPF) Specification R1.0
http://www.dig64.org/home/DIG64_HPPF_R1_0.pdf
The changes have been tested with simulated _OST methods.
v2:
- Added CONFIG_ACPI_HOTPLUG_OST option.
- Added _OST support for container hotplug and sysfs eject.
- Reordered patchset to enable _OST support bit of _OSC in the
last patch.
