235	  <http://ibm-acpi.sf.net/> .
236
237	  This driver was formerly known as ibm-acpi.
238
239	  Extra functionality will be available if the rfkill (CONFIG_RFKILL)
240	  and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
241	  Note that if you want ThinkPad-ACPI to be built-in instead of
242	  modular, ALSA and rfkill will also have to be built-in.
243

253	  Enables monitoring of the built-in console audio output control

256
257	  If this option is enabled, ThinkPad-ACPI will export an ALSA card
258	  with a single read-only mixer control, which should be used for
259	  on-screen-display feedback purposes by the Desktop Environment.
260
261	  Optionally, the driver will also allow software control (the
262	  ALSA mixer will be made read-write).  Please refer to the driver
263	  documentation for details.
264
265	  All IBM models have both volume and mute control.  Newer Lenovo
266	  models only have mute control (the volume hotkeys are just normal

291	bool "Allow control of important LEDs (unsafe)"
292	depends on THINKPAD_ACPI
293	default n
294	---help---
295	  Overriding LED state on ThinkPads can mask important
296	  firmware alerts (like critical battery condition), or misled
297	  the user into damaging the hardware (undocking or ejecting
298	  the bay while buses are still active), etc.
299
300	  LED control on the ThinkPad is write-only (with very few
301	  exceptions on very ancient models), which makes it
302	  impossible to know beforehand if important information will
303	  be lost when one changes LED state.
304
305	  Users that know what they are doing can enable this option
306	  and the driver will allow control of every LED, including
307	  the ones on the dock stations.
308
309	  Never enable this option on a distribution kernel.
310
311	  Say N here, unless you are building a kernel for your own
312	  use, and need to control the important firmware LEDs.

314config THINKPAD_ACPI_VIDEO
315	bool "Video output control support"

319	  Allows the thinkpad_acpi driver to provide an interface to control
320	  the various video output ports.
321
322	  This feature often won't work well, depending on ThinkPad model,
323	  display state, video output devices in use, whether there is a X
324	  server running, phase of the moon, and the current mood of
325	  Schroedinger's cat.  If you can use X.org's RandR to control
326	  your ThinkPad's video output ports instead of this feature,
327	  don't think twice: do it and say N here to save memory and avoid
328	  bad interactions with X.org.
329
330	  NOTE: access to this feature is limited to processes with the
331	  CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
332	  where it interacts badly with X.org.
333
334	  If you are not sure, say Y here but do try to check if you could
335	  be using X.org RandR instead.

338	bool "Support NVRAM polling for hot keys"
339	depends on THINKPAD_ACPI
340	default y
341	---help---
342	  Some thinkpad models benefit from NVRAM polling to detect a few of
343	  the hot key press events.  If you know your ThinkPad model does not
344	  need to do NVRAM polling to support any of the hot keys you use,
345	  unselecting this option will save about 1kB of memory.
346
347	  ThinkPads T40 and newer, R52 and newer, and X31 and newer are
348	  unlikely to need NVRAM polling in their latest BIOS versions.
349
350	  NVRAM polling can detect at most the following keys: ThinkPad/Access
351	  IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
352	  Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
353

406
407	  ACPI-WMI is a proprietary extension to ACPI to expose parts of the

410	  made available for userspace to call.
411
412	  The implementation of this in Linux currently only exposes this to
