98 tristate "Fujitsu Laptop Extras"
101 depends on BACKLIGHT_CLASS_DEVICE
103 This is a driver for laptops built by Fujitsu:
105 * P2xxx/P5xxx/S6xxx/S7xxx series Lifebooks
106 * Possibly other Fujitsu laptop models
107 * Tested with S6410 and S7020
109 It adds support for LCD brightness control and some hotkeys.
111 If you have a Fujitsu laptop, say Y or M here.
113 config FUJITSU_LAPTOP_DEBUG
114 bool "Verbose debug mode for Fujitsu Laptop Extras"
115 depends on FUJITSU_LAPTOP
118 Enables extra debug output from the fujitsu extras driver, at the
119 expense of a slight increase in driver size.
121 If you are not sure, say N here.
124 tristate "HP Compaq TC1100 Tablet WMI Extras (EXPERIMENTAL)"
126 depends on EXPERIMENTAL
130 This is a driver for the WMI extensions (wireless and bluetooth power
131 control) of the HP Compaq TC1100 tablet.
134 tristate "HP WMI extras"

158 More information about this driver is available at
159 <http://0pointer.de/lennart/tchibo.html>.
161 If you have an MSI S270 laptop, say Y or M here.
163 config PANASONIC_LAPTOP
164 tristate "Panasonic Laptop Extras"
165 depends on INPUT && ACPI
166 depends on BACKLIGHT_CLASS_DEVICE
168 This driver adds support for access to backlight control and hotkeys
169 on Panasonic Let's Note laptops.
171 If you have a Panasonic Let's note laptop (such as the R1(N variant),
172 R2, R3, R5, T2, W2 and Y2 series), say Y.
175 tristate "Compal Laptop Extras"
177 depends on BACKLIGHT_CLASS_DEVICE
179 This is a driver for laptops built by Compal:
186 It adds support for Bluetooth, WLAN and LCD brightness control.
188 If you have an Compal FL9x/IFL9x/FT00 laptop, say Y or M here.
191 tristate "Sony Laptop Extras"
193 select BACKLIGHT_CLASS_DEVICE
197 This mini-driver drives the SNC and SPIC devices present in the ACPI
198 BIOS of the Sony Vaio laptops.
200 It gives access to some extra laptop functionalities like Bluetooth,
201 screen brightness control, Fn keys and allows powering on/off some
204 Read <file:Documentation/laptops/sony-laptop.txt> for more information.
207 bool "Sonypi compatibility"
208 depends on SONY_LAPTOP
210 Build the sonypi driver compatibility code into the sony-laptop driver.
213 tristate "ThinkPad ACPI Laptop Extras"
216 depends on RFKILL || RFKILL = n
217 select BACKLIGHT_LCD_SUPPORT
218 select BACKLIGHT_CLASS_DEVICE
224 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
225 support for Fn-Fx key combinations, Bluetooth control, video
226 output switching, ThinkLight control, UltraBay eject and more.
227 For more information about this driver see
228 <file:Documentation/laptops/thinkpad-acpi.txt> and
229 <http://ibm-acpi.sf.net/> .
231 This driver was formerly known as ibm-acpi.
233 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
235 config THINKPAD_ACPI_DEBUGFACILITIES
236 bool "Maintainer debug facilities"
237 depends on THINKPAD_ACPI
240 Enables extra stuff in the thinkpad-acpi which is completely useless
241 for normal use. Read the driver source to find out what it does.
243 Say N here, unless you were told by a kernel maintainer to do
246 config THINKPAD_ACPI_DEBUG
247 bool "Verbose debug mode"
248 depends on THINKPAD_ACPI
251 Enables extra debugging information, at the expense of a slightly
252 increase in driver size.
254 If you are not sure, say N here.
256 config THINKPAD_ACPI_UNSAFE_LEDS
257 bool "Allow control of important LEDs (unsafe)"
258 depends on THINKPAD_ACPI
261 Overriding LED state on ThinkPads can mask important
262 firmware alerts (like critical battery condition), or misled
263 the user into damaging the hardware (undocking or ejecting
264 the bay while buses are still active), etc.
266 LED control on the ThinkPad is write-only (with very few
267 exceptions on very ancient models), which makes it
268 impossible to know beforehand if important information will
269 be lost when one changes LED state.
271 Users that know what they are doing can enable this option
272 and the driver will allow control of every LED, including
273 the ones on the dock stations.
275 Never enable this option on a distribution kernel.
277 Say N here, unless you are building a kernel for your own
278 use, and need to control the important firmware LEDs.
280 config THINKPAD_ACPI_DOCK
281 bool "Legacy Docking Station Support"
282 depends on THINKPAD_ACPI
283 depends on ACPI_DOCK=n
286 Allows the thinkpad_acpi driver to handle docking station events.
287 This support was made obsolete by the generic ACPI docking station
288 support (CONFIG_ACPI_DOCK). It will allow locking and removing the
289 laptop from the docking station, but will not properly connect PCI
292 If you are not sure, say N here.
294 config THINKPAD_ACPI_BAY
295 bool "Legacy Removable Bay Support"
296 depends on THINKPAD_ACPI
299 Allows the thinkpad_acpi driver to handle removable bays. It will
300 electrically disable the device in the bay, and also generate
301 notifications when the bay lever is ejected or inserted.
303 If you are not sure, say Y here.
305 config THINKPAD_ACPI_VIDEO
306 bool "Video output control support"
307 depends on THINKPAD_ACPI
310 Allows the thinkpad_acpi driver to provide an interface to control
311 the various video output ports.
313 This feature often won't work well, depending on ThinkPad model,
314 display state, video output devices in use, whether there is a X
315 server running, phase of the moon, and the current mood of
316 Schroedinger's cat. If you can use X.org's RandR to control
317 your ThinkPad's video output ports instead of this feature,
318 don't think twice: do it and say N here to save some memory.
320 If you are not sure, say Y here.
322 config THINKPAD_ACPI_HOTKEY_POLL
323 bool "Support NVRAM polling for hot keys"
324 depends on THINKPAD_ACPI
327 Some thinkpad models benefit from NVRAM polling to detect a few of
328 the hot key press events. If you know your ThinkPad model does not
329 need to do NVRAM polling to support any of the hot keys you use,
330 unselecting this option will save about 1kB of memory.
332 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
333 unlikely to need NVRAM polling in their latest BIOS versions.
335 NVRAM polling can detect at most the following keys: ThinkPad/Access
336 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
337 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
339 If you are not sure, say Y here. The driver enables polling only if
340 it is strictly necessary to do so.
343 tristate "Thermal Management driver for Intel menlow platform"
344 depends on ACPI_THERMAL
347 ACPI thermal management enhancement driver on
348 Intel Menlow platform.
353 tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
356 depends on EXPERIMENTAL
357 depends on RFKILL || RFKILL = n
358 select BACKLIGHT_CLASS_DEVICE
361 This driver supports the Fn-Fx keys on Eee PC laptops.
363 It also gives access to some extra laptop functionalities like
364 Bluetooth, backlight and allows powering on/off some other
367 If you have an Eee PC laptop, say Y or M here.
374 This driver adds support for the ACPI-WMI (Windows Management
375 Instrumentation) mapper device (PNP0C14) found on some systems.
377 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
378 ACPI firmware to userspace - this is done through various vendor
379 defined methods and data blocks in a PNP0C14 device, which are then
380 made available for userspace to call.
382 The implementation of this in Linux currently only exposes this to
383 other kernel space drivers.
385 This driver is a required dependency to build the firmware specific
386 drivers needed on many machines, including Acer and HP laptops.
388 It is safe to enable this driver even if your DSDT doesn't define
389 any ACPI-WMI devices.
392 tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
394 select BACKLIGHT_CLASS_DEVICE
396 This driver provides support for extra features of ACPI-compatible
397 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
398 support some Medion laptops (such as 9675 for example). It makes all
399 the extra buttons generate standard ACPI events that go through
400 /proc/acpi/events, and (on some models) adds support for changing the
401 display brightness and output, switching the LCD backlight on and off,
402 and most importantly, allows you to blink those fancy LEDs intended
403 for reporting mail and wireless status.
405 Note: display switching code is currently considered EXPERIMENTAL,
406 toying with these values may even lock your machine.
408 All settings are changed via /proc/acpi/asus directory entries. Owner
409 and group for these entries can be set with asus_uid and asus_gid
412 More information and a userspace daemon for handling the extra buttons
413 at <http://acpi4asus.sf.net>.
415 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
416 driver is still under development, so if your laptop is unsupported or
417 something works not quite as expected, please use the mailing list
418 available on the above page (acpi4asus-user@lists.sourceforge.net).
420 NOTE: This driver is deprecated and will probably be removed soon,
421 use asus-laptop instead.
424 tristate "Toshiba Laptop Extras"
427 depends on RFKILL || RFKILL = n
429 select BACKLIGHT_CLASS_DEVICE
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.
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,
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.
447 More information about this driver is available at
448 <http://memebeam.org/toys/ToshibaAcpiDriver>.
