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

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

  158. support some Medion laptops (such as 9675 for example). It makes all
  159. the extra buttons generate standard ACPI events that go through
  160. /proc/acpi/events, and (on some models) adds support for changing the
  161. display brightness and output, switching the LCD backlight on and off,
  162. and most importantly, allows you to blink those fancy LEDs intended
  163. for reporting mail and wireless status.
  164. Note: display switching code is currently considered EXPERIMENTAL,
  165. toying with these values may even lock your machine.
  166. All settings are changed via /proc/acpi/asus directory entries. Owner

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