  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
  34. available at:

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

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

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