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.

478 ThinkPads starting with the R50, T41, and X40 are supported. The

512 For more information about this driver see
513 <file:Documentation/admin-guide/laptops/thinkpad-acpi.rst> and

516 This driver was formerly known as ibm-acpi.
518 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
519 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
520 Note that if you want ThinkPad-ACPI to be built-in instead of
521 modular, ALSA and rfkill will also have to be built-in.
523 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
525 config THINKPAD_ACPI_ALSA_SUPPORT
526 bool "Console audio control ALSA interface"
527 depends on THINKPAD_ACPI
529 depends on SND = y || THINKPAD_ACPI = SND
532 Enables monitoring of the built-in console audio output control
533 (headphone and speakers), which is operated by the mute and (in
534 some ThinkPad models) volume hotkeys.
536 If this option is enabled, ThinkPad-ACPI will export an ALSA card
537 with a single read-only mixer control, which should be used for
538 on-screen-display feedback purposes by the Desktop Environment.
540 Optionally, the driver will also allow software control (the
541 ALSA mixer will be made read-write). Please refer to the driver
542 documentation for details.
544 All IBM models have both volume and mute control. Newer Lenovo
545 models only have mute control (the volume hotkeys are just normal
546 keys and volume control is done through the main HDA mixer).

558 config THINKPAD_ACPI_DEBUG
559 bool "Verbose debug mode"

565 If you are not sure, say N here.
567 config THINKPAD_ACPI_UNSAFE_LEDS
568 bool "Allow control of important LEDs (unsafe)"
569 depends on THINKPAD_ACPI
571 Overriding LED state on ThinkPads can mask important
572 firmware alerts (like critical battery condition), or misled
573 the user into damaging the hardware (undocking or ejecting
574 the bay while buses are still active), etc.
576 LED control on the ThinkPad is write-only (with very few
577 exceptions on very ancient models), which makes it
578 impossible to know beforehand if important information will
579 be lost when one changes LED state.
581 Users that know what they are doing can enable this option
582 and the driver will allow control of every LED, including
583 the ones on the dock stations.
585 Never enable this option on a distribution kernel.
587 Say N here, unless you are building a kernel for your own
588 use, and need to control the important firmware LEDs.
590 config THINKPAD_ACPI_VIDEO
591 bool "Video output control support"
592 depends on THINKPAD_ACPI
595 Allows the thinkpad_acpi driver to provide an interface to control
596 the various video output ports.
598 This feature often won't work well, depending on ThinkPad model,
599 display state, video output devices in use, whether there is a X
600 server running, phase of the moon, and the current mood of
601 Schroedinger's cat. If you can use X.org's RandR to control
602 your ThinkPad's video output ports instead of this feature,
603 don't think twice: do it and say N here to save memory and avoid
604 bad interactions with X.org.
606 NOTE: access to this feature is limited to processes with the
607 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
608 where it interacts badly with X.org.
610 If you are not sure, say Y here but do try to check if you could
611 be using X.org RandR instead.
613 config THINKPAD_ACPI_HOTKEY_POLL
614 bool "Support NVRAM polling for hot keys"
615 depends on THINKPAD_ACPI
618 Some thinkpad models benefit from NVRAM polling to detect a few of
619 the hot key press events. If you know your ThinkPad model does not
620 need to do NVRAM polling to support any of the hot keys you use,
621 unselecting this option will save about 1kB of memory.
623 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
624 unlikely to need NVRAM polling in their latest BIOS versions.
626 NVRAM polling can detect at most the following keys: ThinkPad/Access
627 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
628 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

974 Certain ACPI based tablets with e.g. Silead or Chipone touchscreens
975 do not have enough data in ACPI tables for the touchscreen driver to
976 handle the touchscreen properly, as OEMs expect the data to be baked
977 into the tablet model specific version of the driver shipped with the
978 the OS-image for the device. This option supplies the missing info.
979 Enable this for x86 tablets with Silead or Chipone touchscreens.
981 config X86_ANDROID_TABLETS
982 tristate "X86 Android tablet support"
983 depends on I2C && SPI && SERIAL_DEV_BUS && ACPI && EFI && GPIOLIB
985 X86 tablets which ship with Android as (part of) the factory image
986 typically have various problems with their DSDTs. The factory kernels
987 shipped on these devices typically have device addresses and GPIOs
988 hardcoded in the kernel, rather than specified in their DSDT.
990 With the DSDT containing a random collection of devices which may or
991 may not actually be present. This driver contains various fixes for
992 such tablets, including instantiating kernel devices for devices which
993 are missing from the DSDT.

996 distro config say M here.
1002 bool "Intel Isolated Memory Region support"
1003 depends on X86_INTEL_QUARK && IOSF_MBI
1005 This option provides a means to manipulate Isolated Memory Regions.
1006 IMRs are a set of registers that define read and write access masks
1007 to prohibit certain system agents from accessing memory with 1 KiB
1010 IMRs make it possible to control read/write access to an address
1011 by hardware agents inside the SoC. Read and write masks can be
1014 - Dirty CPU snoop (write only)
1016 - PCI Virtual Channel 0/Virtual Channel 1
