507 This driver adds support for the ACPI-WMI (Windows Management
508 Instrumentation) mapper device (PNP0C14) found on some systems.
509
510 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
511 ACPI firmware to userspace - this is done through various vendor
512 defined methods and data blocks in a PNP0C14 device, which are then
513 made available for userspace to call.
514
515 The implementation of this in Linux currently only exposes this to
516 other kernel space drivers.
517
518 This driver is a required dependency to build the firmware specific
519 drivers needed on many machines, including Acer and HP laptops.

521 It is safe to enable this driver even if your DSDT doesn't define

542 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
543 support some Medion laptops (such as 9675 for example). It makes all
544 the extra buttons generate standard ACPI events that go through
545 /proc/acpi/events, and (on some models) adds support for changing the
546 display brightness and output, switching the LCD backlight on and off,
547 and most importantly, allows you to blink those fancy LEDs intended
548 for reporting mail and wireless status.
549
550 Note: display switching code is currently considered EXPERIMENTAL,
551 toying with these values may even lock your machine.
552
553 All settings are changed via /proc/acpi/asus directory entries. Owner
554 and group for these entries can be set with asus_uid and asus_gid
555 parameters.

589 This driver adds support for access to certain system settings

591 their lack of a BIOS setup menu and APM support.
592
593 On these machines, all system configuration is handled through the
594 ACPI. This driver is required for access to controls not covered
595 by the general ACPI drivers, such as LCD brightness, video output,
596 etc.
597
598 This driver differs from the non-ACPI Toshiba laptop driver (located
599 under "Processor type and features") in several aspects.
600 Configuration is accessed by reading and writing text files in the
601 /proc tree instead of by program interface to /dev. Furthermore, no
602 power management functions are exposed, as those are handled by the
603 general ACPI drivers.

686 The restricted access region control registers
687 (rar_registers) are used to pass address and
688 locking information on restricted access regions
689 to other drivers that use restricted access regions.
690
691 The restricted access regions are regions of memory
692 on the Intel MID Platform that are not accessible to
693 the x86 processor, but are accessible to dedicated
694 processors on board peripheral devices.
695
696 The purpose of the restricted access regions is to

698 programs running on the x86 processor.
