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.

654 If this option is enabled, ThinkPad-ACPI will export an ALSA card
655 with a single read-only mixer control, which should be used for
656 on-screen-display feedback purposes by the Desktop Environment.
658 Optionally, the driver will also allow software control (the
659 ALSA mixer will be made read-write). Please refer to the driver
660 documentation for details.
662 All IBM models have both volume and mute control. Newer Lenovo

685 config THINKPAD_ACPI_UNSAFE_LEDS
686 bool "Allow control of important LEDs (unsafe)"
687 depends on THINKPAD_ACPI
689 Overriding LED state on ThinkPads can mask important
690 firmware alerts (like critical battery condition), or misled
691 the user into damaging the hardware (undocking or ejecting
692 the bay while buses are still active), etc.
694 LED control on the ThinkPad is write-only (with very few
695 exceptions on very ancient models), which makes it
696 impossible to know beforehand if important information will
697 be lost when one changes LED state.
699 Users that know what they are doing can enable this option
700 and the driver will allow control of every LED, including
701 the ones on the dock stations.
703 Never enable this option on a distribution kernel.

710 depends on THINKPAD_ACPI
713 Allows the thinkpad_acpi driver to provide an interface to control
714 the various video output ports.
716 This feature often won't work well, depending on ThinkPad model,
717 display state, video output devices in use, whether there is a X
718 server running, phase of the moon, and the current mood of
719 Schroedinger's cat. If you can use X.org's RandR to control
720 your ThinkPad's video output ports instead of this feature,
721 don't think twice: do it and say N here to save memory and avoid
722 bad interactions with X.org.
724 NOTE: access to this feature is limited to processes with the
725 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
726 where it interacts badly with X.org.

729 be using X.org RandR instead.

732 bool "Support NVRAM polling for hot keys"
733 depends on THINKPAD_ACPI
736 Some thinkpad models benefit from NVRAM polling to detect a few of
737 the hot key press events. If you know your ThinkPad model does not
738 need to do NVRAM polling to support any of the hot keys you use,
739 unselecting this option will save about 1kB of memory.
741 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
742 unlikely to need NVRAM polling in their latest BIOS versions.
744 NVRAM polling can detect at most the following keys: ThinkPad/Access
745 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
746 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

777 The INT33FE ACPI device has a CRS table with I2cSerialBusV2
778 resources for Fuel Gauge Controller and (in the Type-C variant)
779 FUSB302 USB Type-C Controller and PI3USB30532 USB switch.
780 This driver instantiates i2c-clients for these, so that standard
781 i2c drivers for these chips can bind to the them.
