ACPI/OSPM support for Linux is currently under development. As such,
this support is preliminary and EXPERIMENTAL. Configuring ACPI
support enables kernel interfaces that allow higher level software
(OSPM) to manipulate ACPI defined hardware and software interfaces,
including the evaluation of ACPI control methods. If unsure, choose
N here. Note, this option will enlarge your kernel by about 120K.
This support requires an ACPI compliant platform (hardware/firmware).
If both ACPI and Advanced Power Management (APM) support are
configured, whichever is loaded first shall be used.
This code DOES NOT currently provide a complete OSPM implementation
-- it has not yet reached APM's level of functionality. When fully
implemented, Linux ACPI/OSPM will provide a more robust functional
replacement for legacy configuration and power management
interfaces, including the Plug-and-Play BIOS specification (PnP
BIOS), the Multi-Processor Specification (MPS), and the Advanced
Power Management specification (APM).
Linux support for ACPI/OSPM is based on Intel Corporation's ACPI
Component Architecture (ACPI CA). The latest ACPI CA source code,
documentation, debug builds, and implementation status information
can be downloaded from:
<http://developer.intel.com/technology/iapc/acpi/downloads.htm>.
The ACPI Sourceforge project may also be of interest:
