10 bool "ACPI (Advanced Configuration and Power Interface) Support"
16 Advanced Configuration and Power Interface (ACPI) support for
17 Linux requires an ACPI-compliant platform (hardware/firmware),
22 Linux ACPI provides a robust functional replacement for several
26 Management (APM) specification. If both ACPI and APM support
27 are configured, ACPI is used.
29 The project home page for the Linux ACPI subsystem is here:
30 <https://01.org/linux-acpi>
32 Linux support for ACPI is based on Intel Corporation's ACPI
33 Component Architecture (ACPI CA). For more information on the
34 ACPI CA, see:
37 ACPI is an open industry specification originally co-developed by
39 it is developed by the ACPI Specification Working Group (ASWG) under

132 The kernel accesses the EC through ACPI parsed code provided by BIOS
133 tables. This option allows to access the EC directly without ACPI
135 Thus this option is a debug option that helps to write ACPI drivers
136 and can be used to identify ACPI code or EC firmware bugs.
