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

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