Subject: [PATCH v4 0/6] ACPI: Add _OST support for ACPI hotplug
Date: Wed, 23 May 2012 20:25:18 -0600 [thread overview]
Message-ID: <1337826324-16802-1-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
an ACPI hotplug operation has completed, OSPM calls _OST to indicate
the result of the operation to the platform. If a platform does not
support _OST, this patchset has no effect on the platform.
This _OST support is enabled when all relevant ACPI hotplug operations,
such as CPU, memory and container hotplug, are enabled. This assures
consistent behavior among the hotplug operations with regarding the
_OST support.
Some platforms may require the OS to support _OST in order to support
ACPI hotplug operations. For example, if a platform has the management
console where user can request a hotplug operation from, this _OST
support would be required for the management console to show the result
of the hotplug request to user.
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.
v4:
- Removed CONFIG_ACPI_HOTPLUG_OST option.
v3:
- Added more descriptions to the change logs.
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.
