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.

627 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
628 support for Fn-Fx key combinations, Bluetooth control, video
629 output switching, ThinkLight control, UltraBay eject and more.
630 For more information about this driver see
631 <file:Documentation/admin-guide/laptops/thinkpad-acpi.rst> and
632 <http://ibm-acpi.sf.net/> .
633
634 This driver was formerly known as ibm-acpi.
635
636 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
637 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
638 Note that if you want ThinkPad-ACPI to be built-in instead of
639 modular, ALSA and rfkill will also have to be built-in.
640

650 Enables monitoring of the built-in console audio output control
651 (headphone and speakers), which is operated by the mute and (in
652 some ThinkPad models) volume hotkeys.
653
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.
657
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.
661
662 All IBM models have both volume and mute control. Newer Lenovo
663 models only have mute control (the volume hotkeys are just normal
664 keys and volume control is done through the main HDA mixer).

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.
693
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.
698
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.

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

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.
723
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.

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.
740
741 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
742 unlikely to need NVRAM polling in their latest BIOS versions.
743
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).

749 it is strictly necessary to do so.

754 help
755 Many Bay Trail and Cherry Trail devices come with a camera attached
756 to Intel's Image Signal Processor. Linux currently does not have a
757 driver for these, so they do not work as a camera. Some of these
758 camera's have a LED which is controlled through a GPIO.
759
760 Some of these devices have a firmware issue where the LED gets turned
761 on at boot. This driver will turn the LED off at boot and also allows
762 controlling the LED (repurposing it) through the sysfs LED interface.
763
764 Which GPIO is attached to the LED is usually not described in the
765 ACPI tables, so this driver contains per-system info about the GPIO
766 inside the driver, this means that this driver only works on systems

796 with USB Type-C and Micro-B connectors. This driver supports both.

799 resources for Fuel Gauge Controller and (in the Type-C variant)
800 FUSB302 USB Type-C Controller and PI3USB30532 USB switch.

1188 firmware-node. This driver will instantiate separate i2c-clients
1189 for each device in the firmware-node.

1221 help
1222 This option provides a means to manipulate Isolated Memory Regions.
1223 IMRs are a set of registers that define read and write access masks
1224 to prohibit certain system agents from accessing memory with 1 KiB
1225 granularity.
1226
1227 IMRs make it possible to control read/write access to an address
1228 by hardware agents inside the SoC. Read and write masks can be
1229 defined for:
1230 - eSRAM flush
1231 - Dirty CPU snoop (write only)
1232 - RMU access
1233 - PCI Virtual Channel 0/Virtual Channel 1
1234 - SMM mode
1235 - Non SMM mode

1237 Quark contains a set of eight IMR registers and makes use of those
1238 registers during its bootup process.

1267 help
1268 Intel Smart Connect is a technology intended to permit devices to
1269 update state by resuming for a short period of time at regular
1270 intervals. If a user enables this functionality under Windows and
1271 then reboots into Linux, the system may remain configured to resume
1272 on suspend. In the absence of any userspace to support it, the system
1273 will then remain awake until something triggers another suspend.

1275 This driver checks to determine whether the device has Intel Smart
1276 Connect enabled, and if so disables it.
