Subject: [PATCH 0/5] ACPI: Add _OST support for ACPI hotplug
Date: Tue, 10 Apr 2012 16:21:46 -0600 [thread overview]
Message-ID: <1334096510-17319-1-git-send-email-toshi.kani@hp.com> (raw)
This series of patches supports ACPI _OST (OSPM Status Indication)
method for ACPI-based CPU and memory hotplug operations. After
ACPI-based hotplug operation completed, OSPM calls _OST to convey
the completion status to ACPI firmware. If _OST is not present,
this change 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 change was tested by overriding DSDT with fake _OST methods.
