ACPI — ACPI Support
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.
