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, whichever is loaded first shall be used.
|
|
|
|
The ACPI SourceForge project contains the latest source code,
|
|
documentation, tools, mailing list subscription, and other
|
|
information. This project is available at:
|
|
<http://sourceforge.net/projects/acpi>
|
|
|
|
Linux support for ACPI is based on Intel Corporation's ACPI
|
|
Component Architecture (ACPI CA). For more information see:
|
|
<http://developer.intel.com/technology/iapc/acpi>
|
|
|
|
ACPI is an open industry specification co-developed by Compaq,
|
|
Intel, Microsoft, Phoenix, and Toshiba. The specification is
|
|
available at:

---help---
|
|
This option adds support for ACPI suspend states.
|
|
|
|
With this option, you will be able to put the system "to sleep".
|
|
Sleep states are low power states for the system and devices. All
|
|
of the system operating state is saved to either memory or disk
|
|
(depending on the state), to allow the system to resume operation
|
|
quickly at your request.
|
|
|
|
Although this option sounds really nifty, barely any of the device
|
|
drivers have been converted to the new driver model and hence few
|
|
have proper power management support.
|
|
|
|
This option is not recommended for anyone except those doing driver
|
|
power management development.

This driver provides support for extra features of ACPI-compatible
|
|
ASUS laptops. As some of Medion laptops are made by ASUS, it may also
|
|
support some Medion laptops (such as 9675 for example). It makes all
|
|
the extra buttons generate standard ACPI events that go through
|
|
/proc/acpi/events, and (on some models) adds support for changing the
|
|
display brightness and output, switching the LCD backlight on and off,
|
|
and most importantly, allows you to blink those fancy LEDs intended
|
|
for reporting mail and wireless status.
|
|
|
|
Note: display switching code is currently considered EXPERIMENTAL,
|
|
toying with these values may even lock your machine.
|
|
|
|
All settings are changed via /proc/acpi/asus directory entries. Owner
|
|
and group for these entries can be set with asus_uid and asus_gid
|
|
parameters.

This driver adds support for access to certain system settings

on "legacy free" Toshiba laptops. These laptops can be recognized by
|
|
their lack of a BIOS setup menu and APM support.
|
|
|
|
On these machines, all system configuration is handled through the
|
|
ACPI. This driver is required for access to controls not covered
|
|
by the general ACPI drivers, such as LCD brightness, video output,
|
|
etc.
|
|
|
|
This driver differs from the non-ACPI Toshiba laptop driver (located
|
|
under "Processor type and features") in several aspects.
|
|
Configuration is accessed by reading and writing text files in the
|
|
/proc tree instead of by program interface to /dev. Furthermore, no
|
|
power management functions are exposed, as those are handled by the
|
|
general ACPI drivers.
