      Advanced Configuration and Power Interface (ACPI) support for 

      Linux requires an ACPI-compliant platform (hardware/firmware),

      and assumes the presence of OS-directed configuration and power

      management (OSPM) software.  This option will enlarge your 

      kernel by about 70K.

​

      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, ACPI is used.

​

      The project home page for the Linux ACPI subsystem is here:

      <https://01.org/linux-acpi>

​

      Linux support for ACPI is based on Intel Corporation's ACPI

      Component Architecture (ACPI CA).  For more information on the

      ACPI CA, see:

      <http://acpica.org/>

​

      ACPI is an open industry specification originally co-developed by

      Hewlett-Packard, Intel, Microsoft, Phoenix, and Toshiba. Currently,

      it is developed by the ACPI Specification Working Group (ASWG) under

      the UEFI Forum and any UEFI member can join the ASWG and contribute

      to the ACPI specification.

      The specification is available at:

      <http://www.acpi.info>
