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

307 with a single read-only mixer control, which should be used for

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.

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,

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
