3 Advanced Configuration and Power Interface (ACPI) support for Linux requires an
|
|
al@19583
|
4 ACPI-compliant platform (hardware/firmware), and assumes the presence of
|
|
al@19583
|
5 OS-directed configuration and power management (OSPM) software.

7 Linux ACPI provides a robust functional replacement for several legacy
|
|
al@19583
|
8 configuration and power management interfaces, including the Plug-and-Play BIOS
|
|
al@19583
|
9 specification (PnP BIOS), the MultiProcessor Specification (MPS), and the
|
|
al@19583
|
10 Advanced Power Management (APM) specification. If both ACPI and APM support are
|
|
al@19583
|
11 configured, ACPI is used.

16 Linux support for ACPI is based on Intel Corporation's ACPI Component
|
|
al@19583
|
17 Architecture (ACPI CA). For more information on the ACPI CA, see:

20 ACPI is an open industry specification originally co-developed by
|
|
al@19583
|
21 Hewlett-Packard, Intel, Microsoft, Phoenix, and Toshiba. Currently, it is
|
|
al@19583
|
22 developed by the ACPI Specification Working Group (ASWG) under the UEFI Forum
|
|
al@19583
|
23 and any UEFI member can join the ASWG and contribute to the ACPI specification.
