  209. Optionally, the driver will also allow software control (the
  210. ALSA mixer will be made read-write). Please refer to the driver
  211. documentation for details.

  237. Overriding LED state on ThinkPads can mask important
  238. firmware alerts (like critical battery condition), or misled
  239. the user into damaging the hardware (undocking or ejecting
  240. the bay while buses are still active), etc.
  241. LED control on the ThinkPad is write-only (with very few
  242. exceptions on very ancient models), which makes it
  243. impossible to know beforehand if important information will
  244. be lost when one changes LED state.
  245. Users that know what they are doing can enable this option
  246. and the driver will allow control of every LED, including
  247. the ones on the dock stations.
  248. Never enable this option on a distribution kernel.
  249. Say N here, unless you are building a kernel for your own
  250. use, and need to control the important firmware LEDs.

  260. server running, phase of the moon, and the current mood of
  261. Schroedinger's cat. If you can use X.org's RandR to control
  262. your ThinkPad's video output ports instead of this feature,
  263. don't think twice: do it and say N here to save memory and avoid
  264. bad interactions with X.org.
  265. NOTE: access to this feature is limited to processes with the
  266. CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
  267. where it interacts badly with X.org.
  268. If you are not sure, say Y here but do try to check if you could

  273. default y
  274. ---help---
  275. Some thinkpad models benefit from NVRAM polling to detect a few of
  276. the hot key press events. If you know your ThinkPad model does not
  277. need to do NVRAM polling to support any of the hot keys you use,
  278. unselecting this option will save about 1kB of memory.
  279. ThinkPads T40 and newer, R52 and newer, and X31 and newer are
  280. unlikely to need NVRAM polling in their latest BIOS versions.
  281. NVRAM polling can detect at most the following keys: ThinkPad/Access
  282. IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
  283. Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

  316. This driver adds support for the ACPI-WMI (Windows Management

  318. ACPI-WMI is a proprietary extension to ACPI to expose parts of the
  319. ACPI firmware to userspace - this is done through various vendor
  320. defined methods and data blocks in a PNP0C14 device, which are then
  321. made available for userspace to call.

  323. other kernel space drivers.
  324. This driver is a required dependency to build the firmware specific

  349. and most importantly, allows you to blink those fancy LEDs intended
  350. for reporting mail and wireless status.
  351. Note: display switching code is currently considered EXPERIMENTAL,
  352. toying with these values may even lock your machine.
  353. All settings are changed via /proc/acpi/asus directory entries. Owner

  381. their lack of a BIOS setup menu and APM support.
  382. On these machines, all system configuration is handled through the
  383. ACPI. This driver is required for access to controls not covered
  384. by the general ACPI drivers, such as LCD brightness, video output,
  385. etc.
  386. This driver differs from the non-ACPI Toshiba laptop driver (located
  387. under "Processor type and features") in several aspects.
  388. Configuration is accessed by reading and writing text files in the
  389. /proc tree instead of by program interface to /dev. Furthermore, no
  390. power management functions are exposed, as those are handled by the
  391. general ACPI drivers.
