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.

518 This driver was formerly known as ibm-acpi.
520 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
521 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
522 Note that if you want ThinkPad-ACPI to be built-in instead of
523 modular, ALSA and rfkill will also have to be built-in.

528 bool "Console audio control ALSA interface"
529 depends on THINKPAD_ACPI
531 depends on SND = y || THINKPAD_ACPI = SND
534 Enables monitoring of the built-in console audio output control
535 (headphone and speakers), which is operated by the mute and (in
536 some ThinkPad models) volume hotkeys.
538 If this option is enabled, ThinkPad-ACPI will export an ALSA card
539 with a single read-only mixer control, which should be used for
540 on-screen-display feedback purposes by the Desktop Environment.
542 Optionally, the driver will also allow software control (the
543 ALSA mixer will be made read-write). Please refer to the driver
544 documentation for details.
546 All IBM models have both volume and mute control. Newer Lenovo
547 models only have mute control (the volume hotkeys are just normal
548 keys and volume control is done through the main HDA mixer).

560 config THINKPAD_ACPI_DEBUG
561 bool "Verbose debug mode"

564 Enables extra debugging information, at the expense of a slightly

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

1012 IMRs are a set of registers that define read and write access masks
1013 to prohibit certain system agents from accessing memory with 1 KiB
1016 IMRs make it possible to control read/write access to an address
1017 by hardware agents inside the SoC. Read and write masks can be
1020 - Dirty CPU snoop (write only)
1022 - PCI Virtual Channel 0/Virtual Channel 1
