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. --- Toshi Kani (4): ACPI: Set hotplug _OST support bit to _OSC ACPI: Add acpi_evaluate_ost() for calling _OST ACPI: Add _OST support for ACPI CPU hotplug ACPI: Add _OST support for ACPI memory hotplug drivers/acpi/acpi_memhotplug.c | 43 +++++++++++++++++++++++++++++---------- drivers/acpi/bus.c | 5 ++++ drivers/acpi/processor_driver.c | 28 ++++++++++++++++++------- drivers/acpi/utils.c | 34 ++++++++++++++++++++++++++++++ include/acpi/acpi_bus.h | 3 ++ include/linux/acpi.h | 26 ++++++++++++++++++++++- 6 files changed, 119 insertions(+), 20 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
