Bjorn Helgaas1c48aa32009-02-19 14:45:47 -070015 Linux requires an ACPI-compliant platform (hardware/firmware),
Linus Torvalds1da177e2005-04-16 15:20:36 -070016 and assumes the presence of OS-directed configuration and power
17 management (OSPM) software. This option will enlarge your

20 Linux ACPI provides a robust functional replacement for several
21 legacy configuration and power management interfaces, including
22 the Plug-and-Play BIOS specification (PnP BIOS), the
23 MultiProcessor Specification (MPS), and the Advanced Power
24 Management (APM) specification. If both ACPI and APM support
Bjorn Helgaas1c48aa32009-02-19 14:45:47 -070025 are configured, ACPI is used.

Thomas Renninger1195a092010-07-16 13:11:31 +020098 An Embedded Controller typically is available on laptops and reads

Thomas Renninger500de3dd2010-07-29 22:30:24 +0200100 The kernel accesses the EC through ACPI parsed code provided by BIOS

102 code being involved.
Thomas Renninger1195a092010-07-16 13:11:31 +0200103 Thus this option is a debug option that helps to write ACPI drivers
