Description
Advanced Configuration and Power Interface (ACPI) support for Linux
requires ACPI-compliant hardware and firmware, and assumes
the presence of OS-directed configuration and power management (OSPM)
software. This option will enlarge your kernel by about 70 KB.
Linux ACPI provides a robust functional replacement for several legacy
configuration and power management interfaces, including the
Plug-and-Play BIOS specification (PnP BIOS), the MultiProcessor
Specification (MPS), and the Advanced Power Management (APM)
specification. If both ACPI and APM support are configured, whichever
is loaded first will be used.
The ACPI SourceForge project at
http://sourceforge.net/projects/acpi contains the latest source code,
documentation, tools, mailing list subscription, and other information.
Linux support for ACPI is based on Intel Corporation's ACPI Component
Architecture (ACPI CA). For more information, see
http://developer.intel.com/technology/iapc/acpi.
ACPI is an open industry specification co-developed by Compaq, Intel,
Microsoft, Phoenix, and Toshiba. The specification is available at
http://www.acpi.info.
