344b4f9fe12SLen Brown	  This driver adds support for the ACPI-WMI (Windows Management
345b4f9fe12SLen Brown	  Instrumentation) mapper device (PNP0C14) found on some systems.
346b4f9fe12SLen Brown
347b4f9fe12SLen Brown	  ACPI-WMI is a proprietary extension to ACPI to expose parts of the
348b4f9fe12SLen Brown	  ACPI firmware to userspace - this is done through various vendor
349b4f9fe12SLen Brown	  defined methods and data blocks in a PNP0C14 device, which are then
350b4f9fe12SLen Brown	  made available for userspace to call.
351b4f9fe12SLen Brown
352b4f9fe12SLen Brown	  The implementation of this in Linux currently only exposes this to
353b4f9fe12SLen Brown	  other kernel space drivers.
354b4f9fe12SLen Brown
355b4f9fe12SLen Brown	  This driver is a required dependency to build the firmware specific
356b4f9fe12SLen Brown	  drivers needed on many machines, including Acer and HP laptops.
357b4f9fe12SLen Brown
358b4f9fe12SLen Brown	  It is safe to enable this driver even if your DSDT doesn't define
359b4f9fe12SLen Brown	  any ACPI-WMI devices.

366b4f9fe12SLen Brown	  This driver provides support for extra features of ACPI-compatible
367b4f9fe12SLen Brown	  ASUS laptops. As some of Medion laptops are made by ASUS, it may also
368b4f9fe12SLen Brown	  support some Medion laptops (such as 9675 for example).  It makes all
369b4f9fe12SLen Brown	  the extra buttons generate standard ACPI events that go through
370b4f9fe12SLen Brown	  /proc/acpi/events, and (on some models) adds support for changing the
371b4f9fe12SLen Brown	  display brightness and output, switching the LCD backlight on and off,
372b4f9fe12SLen Brown	  and most importantly, allows you to blink those fancy LEDs intended
373b4f9fe12SLen Brown	  for reporting mail and wireless status.
374b4f9fe12SLen Brown
375b4f9fe12SLen Brown	  Note: display switching code is currently considered EXPERIMENTAL,
376b4f9fe12SLen Brown	  toying with these values may even lock your machine.
377b4f9fe12SLen Brown
378b4f9fe12SLen Brown	  All settings are changed via /proc/acpi/asus directory entries. Owner
379b4f9fe12SLen Brown	  and group for these entries can be set with asus_uid and asus_gid
380b4f9fe12SLen Brown	  parameters.

385b4f9fe12SLen Brown	  If you have an ACPI-compatible ASUS laptop, say Y or M here. This
386b4f9fe12SLen Brown	  driver is still under development, so if your laptop is unsupported or
387b4f9fe12SLen Brown	  something works not quite as expected, please use the mailing list
388b4f9fe12SLen Brown	  available on the above page (acpi4asus-user@lists.sourceforge.net).

390b4f9fe12SLen Brown	  NOTE: This driver is deprecated and will probably be removed soon,
391b4f9fe12SLen Brown	  use asus-laptop instead.

402b4f9fe12SLen Brown	  This driver adds support for access to certain system settings
403b4f9fe12SLen Brown	  on "legacy free" Toshiba laptops.  These laptops can be recognized by
404b4f9fe12SLen Brown	  their lack of a BIOS setup menu and APM support.
405b4f9fe12SLen Brown
406b4f9fe12SLen Brown	  On these machines, all system configuration is handled through the
407b4f9fe12SLen Brown	  ACPI.  This driver is required for access to controls not covered
408b4f9fe12SLen Brown	  by the general ACPI drivers, such as LCD brightness, video output,
409b4f9fe12SLen Brown	  etc.

411b4f9fe12SLen Brown	  This driver differs from the non-ACPI Toshiba laptop driver (located
412b4f9fe12SLen Brown	  under "Processor type and features") in several aspects.
413b4f9fe12SLen Brown	  Configuration is accessed by reading and writing text files in the
414b4f9fe12SLen Brown	  /proc tree instead of by program interface to /dev.  Furthermore, no
415b4f9fe12SLen Brown	  power management functions are exposed, as those are handled by the
416b4f9fe12SLen Brown	  general ACPI drivers.
