26 the Plug-and-Play BIOS specification (PnP BIOS), the
28 Management (APM) specification. If both ACPI and APM support
29 are configured, ACPI is used.
31 Linux support for ACPI is based on Intel Corporation's ACPI
32 Component Architecture (ACPI CA). For more information on the
33 ACPI CA, see:
36 ACPI is an open industry specification originally co-developed by
37 Hewlett-Packard, Intel, Microsoft, Phoenix, and Toshiba. Currently,
38 it is developed by the ACPI Specification Working Group (ASWG) under

158 Thus this option is a debug option that helps to write ACPI drivers
159 and can be used to identify ACPI code or EC firmware bugs.
