448
449 LED control on the ThinkPad is write-only (with very few

451 impossible to know beforehand if important information will
452 be lost when one changes LED state.

621 This driver adds support for the ACPI-WMI (Windows Management
622 Instrumentation) mapper device (PNP0C14) found on some systems.
623
624 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
625 ACPI firmware to userspace - this is done through various vendor
626 defined methods and data blocks in a PNP0C14 device, which are then
627 made available for userspace to call.
628
629 The implementation of this in Linux currently only exposes this to
630 other kernel space drivers.
631
632 This driver is a required dependency to build the firmware specific
633 drivers needed on many machines, including Acer and HP laptops.
634
635 It is safe to enable this driver even if your DSDT doesn't define
636 any ACPI-WMI devices.

282 For more information about this driver see
283 <file:Documentation/laptops/thinkpad-acpi.txt> and
284 <http://ibm-acpi.sf.net/> .
285
286 This driver was formerly known as ibm-acpi.
287
288 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
289 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
290 Note that if you want ThinkPad-ACPI to be built-in instead of
291 modular, ALSA and rfkill will also have to be built-in.

302 Enables monitoring of the built-in console audio output control
303 (headphone and speakers), which is operated by the mute and (in
304 some ThinkPad models) volume hotkeys.
305
306 If this option is enabled, ThinkPad-ACPI will export an ALSA card
307 with a single read-only mixer control, which should be used for
308 on-screen-display feedback purposes by the Desktop Environment.
309
310 Optionally, the driver will also allow software control (the
311 ALSA mixer will be made read-write). Please refer to the driver
312 documentation for details.
313
314 All IBM models have both volume and mute control. Newer Lenovo
315 models only have mute control (the volume hotkeys are just normal

345 firmware alerts (like critical battery condition), or misled
346 the user into damaging the hardware (undocking or ejecting
347 the bay while buses are still active), etc.
348
349 LED control on the ThinkPad is write-only (with very few
350 exceptions on very ancient models), which makes it
351 impossible to know beforehand if important information will
352 be lost when one changes LED state.
353
354 Users that know what they are doing can enable this option
355 and the driver will allow control of every LED, including
356 the ones on the dock stations.
357
358 Never enable this option on a distribution kernel.

375 your ThinkPad's video output ports instead of this feature,
376 don't think twice: do it and say N here to save memory and avoid
377 bad interactions with X.org.
378
379 NOTE: access to this feature is limited to processes with the
380 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
381 where it interacts badly with X.org.

391 Some thinkpad models benefit from NVRAM polling to detect a few of
392 the hot key press events. If you know your ThinkPad model does not
393 need to do NVRAM polling to support any of the hot keys you use,
394 unselecting this option will save about 1kB of memory.
395
396 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
397 unlikely to need NVRAM polling in their latest BIOS versions.
398
399 NVRAM polling can detect at most the following keys: ThinkPad/Access
400 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
401 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
