23 This driver adds support for the ACPI-WMI (Windows Management
24 Instrumentation) mapper device (PNP0C14) found on some systems.
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.
31 The implementation of this in Linux currently only exposes this to
32 other kernel space drivers.
34 This driver is a required dependency to build the firmware specific
35 drivers needed on many machines, including Acer and HP laptops.

543 System (hdaps), which provides an accelerometer and other misc. data.
544 ThinkPads starting with the R50, T41, and X40 are supported. The

585 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
586 Note that if you want ThinkPad-ACPI to be built-in instead of
587 modular, ALSA and rfkill will also have to be built-in.

598 Enables monitoring of the built-in console audio output control
599 (headphone and speakers), which is operated by the mute and (in
600 some ThinkPad models) volume hotkeys.
602 If this option is enabled, ThinkPad-ACPI will export an ALSA card
603 with a single read-only mixer control, which should be used for
604 on-screen-display feedback purposes by the Desktop Environment.
606 Optionally, the driver will also allow software control (the
607 ALSA mixer will be made read-write). Please refer to the driver
608 documentation for details.
610 All IBM models have both volume and mute control. Newer Lenovo

633 config THINKPAD_ACPI_UNSAFE_LEDS
634 bool "Allow control of important LEDs (unsafe)"
635 depends on THINKPAD_ACPI
637 Overriding LED state on ThinkPads can mask important
638 firmware alerts (like critical battery condition), or misled
639 the user into damaging the hardware (undocking or ejecting
640 the bay while buses are still active), etc.
642 LED control on the ThinkPad is write-only (with very few
643 exceptions on very ancient models), which makes it
644 impossible to know beforehand if important information will
645 be lost when one changes LED state.
647 Users that know what they are doing can enable this option
648 and the driver will allow control of every LED, including
649 the ones on the dock stations.
651 Never enable this option on a distribution kernel.
653 Say N here, unless you are building a kernel for your own
654 use, and need to control the important firmware LEDs.

657 bool "Video output control support"
658 depends on THINKPAD_ACPI
661 Allows the thinkpad_acpi driver to provide an interface to control
662 the various video output ports.
664 This feature often won't work well, depending on ThinkPad model,
665 display state, video output devices in use, whether there is a X
666 server running, phase of the moon, and the current mood of
667 Schroedinger's cat. If you can use X.org's RandR to control
668 your ThinkPad's video output ports instead of this feature,
669 don't think twice: do it and say N here to save memory and avoid
670 bad interactions with X.org.
672 NOTE: access to this feature is limited to processes with the
673 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
674 where it interacts badly with X.org.
676 If you are not sure, say Y here but do try to check if you could
677 be using X.org RandR instead.
679 config THINKPAD_ACPI_HOTKEY_POLL
680 bool "Support NVRAM polling for hot keys"
681 depends on THINKPAD_ACPI
684 Some thinkpad models benefit from NVRAM polling to detect a few of
685 the hot key press events. If you know your ThinkPad model does not
686 need to do NVRAM polling to support any of the hot keys you use,
687 unselecting this option will save about 1kB of memory.
689 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
690 unlikely to need NVRAM polling in their latest BIOS versions.
692 NVRAM polling can detect at most the following keys: ThinkPad/Access
693 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
694 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
696 If you are not sure, say Y here. The driver enables polling only if
697 it is strictly necessary to do so.

830 on "legacy free" Toshiba laptops. These laptops can be recognized by
831 their lack of a BIOS setup menu and APM support.
833 On these machines, all system configuration is handled through the
834 ACPI. This driver is required for access to controls not covered
835 by the general ACPI drivers, such as LCD brightness, video output,
838 This driver differs from the non-ACPI Toshiba laptop driver (located
839 under "Processor type and features") in several aspects.
840 Configuration is accessed by reading and writing text files in the
841 /proc tree instead of by program interface to /dev. Furthermore, no

1048 X86 tablets which ship with Android as (part of) the factory image
1049 typically have various problems with their DSDTs. The factory kernels
1050 shipped on these devices typically have device addresses and GPIOs
1051 hardcoded in the kernel, rather than specified in their DSDT.
1053 With the DSDT containing a random collection of devices which may or
1054 may not actually be present. This driver contains various fixes for
1055 such tablets, including instantiating kernel devices for devices which
1056 are missing from the DSDT.

1074 by hardware agents inside the SoC. Read and write masks can be
1077 - Dirty CPU snoop (write only)
1079 - PCI Virtual Channel 0/Virtual Channel 1
