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).

448
449 LED control on the ThinkPad is write-only (with very few

451 impossible to know beforehand if important information will
452 be lost when one changes LED state.

493 need to do NVRAM polling to support any of the hot keys you use,
494 unselecting this option will save about 1kB of memory.
495
496 ThinkPads T40 and newer, R52 and newer, and X31 and newer are

834 IMRs make it possible to control read/write access to an address
835 by hardware agents inside the SoC. Read and write masks can be
836 defined for:
837 - eSRAM flush
