228 For more information about this driver see
229 <file:Documentation/laptops/thinkpad-acpi.txt> and

257 config THINKPAD_ACPI_UNSAFE_LEDS
258 bool "Allow control of important LEDs (unsafe)"
259 depends on THINKPAD_ACPI
260 default n
261 ---help---
262 Overriding LED state on ThinkPads can mask important
263 firmware alerts (like critical battery condition), or misled
264 the user into damaging the hardware (undocking or ejecting
265 the bay while buses are still active), etc.
266
267 LED control on the ThinkPad is write-only (with very few
268 exceptions on very ancient models), which makes it
269 impossible to know beforehand if important information will
270 be lost when one changes LED state.
271
272 Users that know what they are doing can enable this option
273 and the driver will allow control of every LED, including
274 the ones on the dock stations.
275
276 Never enable this option on a distribution kernel.
277
278 Say N here, unless you are building a kernel for your own
279 use, and need to control the important firmware LEDs.
280

284 default y
285 ---help---
286 Allows the thinkpad_acpi driver to provide an interface to control
287 the various video output ports.
288
289 This feature often won't work well, depending on ThinkPad model,
290 display state, video output devices in use, whether there is a X
291 server running, phase of the moon, and the current mood of
292 Schroedinger's cat. If you can use X.org's RandR to control
293 your ThinkPad's video output ports instead of this feature,
294 don't think twice: do it and say N here to save some memory.
295
296 If you are not sure, say Y here.
297
298 config THINKPAD_ACPI_HOTKEY_POLL
299 bool "Support NVRAM polling for hot keys"
300 depends on THINKPAD_ACPI
301 default y
302 ---help---
303 Some thinkpad models benefit from NVRAM polling to detect a few of
304 the hot key press events. If you know your ThinkPad model does not
305 need to do NVRAM polling to support any of the hot keys you use,
306 unselecting this option will save about 1kB of memory.
307
308 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
309 unlikely to need NVRAM polling in their latest BIOS versions.
310
311 NVRAM polling can detect at most the following keys: ThinkPad/Access
312 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
313 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
314
315 If you are not sure, say Y here. The driver enables polling only if
316 it is strictly necessary to do so.

352 help
353 This driver adds support for the ACPI-WMI (Windows Management
354 Instrumentation) mapper device (PNP0C14) found on some systems.
355
356 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
357 ACPI firmware to userspace - this is done through various vendor
358 defined methods and data blocks in a PNP0C14 device, which are then
359 made available for userspace to call.
360
361 The implementation of this in Linux currently only exposes this to
362 other kernel space drivers.
363
364 This driver is a required dependency to build the firmware specific
365 drivers needed on many machines, including Acer and HP laptops.
366
367 It is safe to enable this driver even if your DSDT doesn't define
368 any ACPI-WMI devices.

385 select BACKLIGHT_CLASS_DEVICE
386 ---help---
387 This driver provides support for extra features of ACPI-compatible
388 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
389 support some Medion laptops (such as 9675 for example). It makes all
390 the extra buttons generate standard ACPI events that go through
391 /proc/acpi/events, and (on some models) adds support for changing the
392 display brightness and output, switching the LCD backlight on and off,
393 and most importantly, allows you to blink those fancy LEDs intended
394 for reporting mail and wireless status.
395
396 Note: display switching code is currently considered EXPERIMENTAL,
397 toying with these values may even lock your machine.
398
399 All settings are changed via /proc/acpi/asus directory entries. Owner
400 and group for these entries can be set with asus_uid and asus_gid
401 parameters.

407 driver is still under development, so if your laptop is unsupported or
408 something works not quite as expected, please use the mailing list
409 available on the above page (acpi4asus-user@lists.sourceforge.net).

431 This driver adds support for access to certain system settings
432 on "legacy free" Toshiba laptops. These laptops can be recognized by
433 their lack of a BIOS setup menu and APM support.
434
435 On these machines, all system configuration is handled through the
436 ACPI. This driver is required for access to controls not covered
437 by the general ACPI drivers, such as LCD brightness, video output,
438 etc.
439
440 This driver differs from the non-ACPI Toshiba laptop driver (located
441 under "Processor type and features") in several aspects.
442 Configuration is accessed by reading and writing text files in the
443 /proc tree instead of by program interface to /dev. Furthermore, no
444 power management functions are exposed, as those are handled by the
445 general ACPI drivers.
