17 Advanced Configuration and Power Interface (ACPI) support for
18 Linux requires an ACPI compliant platform (hardware/firmware),
19 and assumes the presence of OS-directed configuration and power
20 management (OSPM) software. This option will enlarge your
21 kernel by about 70K.
22
23 Linux ACPI provides a robust functional replacement for several
24 legacy configuration and power management interfaces, including
25 the Plug-and-Play BIOS specification (PnP BIOS), the
26 MultiProcessor Specification (MPS), and the Advanced Power
27 Management (APM) specification. If both ACPI and APM support
28 are configured, whichever is loaded first shall be used.
29
30 The ACPI SourceForge project contains the latest source code,
31 documentation, tools, mailing list subscription, and other
32 information. This project is available at:
33 <http://sourceforge.net/projects/acpi>
34
35 Linux support for ACPI is based on Intel Corporation's ACPI
36 Component Architecture (ACPI CA). For more information see:
37 <http://developer.intel.com/technology/iapc/acpi>
38
39 ACPI is an open industry specification co-developed by Compaq,
40 Intel, Microsoft, Phoenix, and Toshiba. The specification is
41 available at:

52 This option adds support for ACPI suspend states.
53
54 With this option, you will be able to put the system "to sleep".
55 Sleep states are low power states for the system and devices. All
56 of the system operating state is saved to either memory or disk
57 (depending on the state), to allow the system to resume operation
58 quickly at your request.
59
60 Although this option sounds really nifty, barely any of the device
61 drivers have been converted to the new driver model and hence few
62 have proper power management support.
