| This is a driver for the IBM and Lenovo ThinkPad laptops. It adds |
| support for Fn-Fx key combinations, Bluetooth control, video |
| output switching, ThinkLight control, UltraBay eject and more. |
| For more information about this driver see |
| <file:Documentation/admin-guide/laptops/thinkpad-acpi.rst> and |
| <http://ibm-acpi.sf.net/> . |
| |
| This driver was formerly known as ibm-acpi. |
| |
| Extra functionality will be available if the rfkill (CONFIG_RFKILL) |
| and/or ALSA (CONFIG_SND) subsystems are available in the kernel. |
| Note that if you want ThinkPad-ACPI to be built-in instead of |
| modular, ALSA and rfkill will also have to be built-in. |
| |
| If you have an IBM or Lenovo ThinkPad laptop, say Y or M here. |

| help |
| Enables monitoring of the built-in console audio output control |
| (headphone and speakers), which is operated by the mute and (in |
| some ThinkPad models) volume hotkeys. |
| |
| If this option is enabled, ThinkPad-ACPI will export an ALSA card |
| with a single read-only mixer control, which should be used for |
| on-screen-display feedback purposes by the Desktop Environment. |
| |
| Optionally, the driver will also allow software control (the |
| ALSA mixer will be made read-write). Please refer to the driver |
| documentation for details. |
| |
| All IBM models have both volume and mute control. Newer Lenovo |
| models only have mute control (the volume hotkeys are just normal |
| keys and volume control is done through the main HDA mixer). |
| |
| config THINKPAD_ACPI_DEBUGFACILITIES |

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