22 help
23 This driver adds support for the ACPI-WMI (Windows Management
24 Instrumentation) mapper device (PNP0C14) found on some systems.
25
26 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
27 ACPI firmware to userspace - this is done through various vendor
28 defined methods and data blocks in a PNP0C14 device, which are then
29 made available for userspace to call.
30
31 The implementation of this in Linux currently only exposes this to
32 other kernel space drivers.
33
34 This driver is a required dependency to build the firmware specific
35 drivers needed on many machines, including Acer and HP laptops.
36
37 It is safe to enable this driver even if your DSDT doesn't define
38 any ACPI-WMI devices.

619 Some thinkpad models benefit from NVRAM polling to detect a few of
620 the hot key press events. If you know your ThinkPad model does not
621 need to do NVRAM polling to support any of the hot keys you use,
622 unselecting this option will save about 1kB of memory.
623
624 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
625 unlikely to need NVRAM polling in their latest BIOS versions.
626
627 NVRAM polling can detect at most the following keys: ThinkPad/Access
628 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
629 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

777 This driver adds support for access to certain system settings
778 on "legacy free" Toshiba laptops. These laptops can be recognized by
779 their lack of a BIOS setup menu and APM support.
780
781 On these machines, all system configuration is handled through the
782 ACPI. This driver is required for access to controls not covered
783 by the general ACPI drivers, such as LCD brightness, video output,
784 etc.
785
786 This driver differs from the non-ACPI Toshiba laptop driver (located
787 under "Processor type and features") in several aspects.
788 Configuration is accessed by reading and writing text files in the
789 /proc tree instead of by program interface to /dev. Furthermore, no
790 power management functions are exposed, as those are handled by the
791 general ACPI drivers.
