92 It adds support for LCD brightness control and some hotkeys.
94 If you have a Fujitsu laptop, say Y or M here.
96 config FUJITSU_LAPTOP_DEBUG
97 bool "Verbose debug mode for Fujitsu Laptop Extras"
98 depends on FUJITSU_LAPTOP
101 Enables extra debug output from the fujitsu extras driver, at the
102 expense of a slight increase in driver size.
104 If you are not sure, say N here.
107 tristate "HP Compaq TC1100 Tablet WMI Extras (EXPERIMENTAL)"
109 depends on EXPERIMENTAL
113 This is a driver for the WMI extensions (wireless and bluetooth power
114 control) of the HP Compaq TC1100 tablet.

141 More information about this driver is available at
142 <http://0pointer.de/lennart/tchibo.html>.
144 If you have an MSI S270 laptop, say Y or M here.
146 config PANASONIC_LAPTOP
147 tristate "Panasonic Laptop Extras"
148 depends on INPUT && ACPI
149 depends on BACKLIGHT_CLASS_DEVICE
151 This driver adds support for access to backlight control and hotkeys
152 on Panasonic Let's Note laptops.
154 If you have a Panasonic Let's note laptop (such as the R1(N variant),
155 R2, R3, R5, T2, W2 and Y2 series), say Y.
158 tristate "Compal Laptop Extras"
160 depends on BACKLIGHT_CLASS_DEVICE
162 This is a driver for laptops built by Compal:
169 It adds support for Bluetooth, WLAN and LCD brightness control.
171 If you have an Compal FL9x/IFL9x/FT00 laptop, say Y or M here.
174 tristate "Sony Laptop Extras"
176 select BACKLIGHT_CLASS_DEVICE
180 This mini-driver drives the SNC and SPIC devices present in the ACPI
181 BIOS of the Sony Vaio laptops.
183 It gives access to some extra laptop functionalities like Bluetooth,
184 screen brightness control, Fn keys and allows powering on/off some
187 Read <file:Documentation/laptops/sony-laptop.txt> for more information.
190 bool "Sonypi compatibility"
191 depends on SONY_LAPTOP
193 Build the sonypi driver compatibility code into the sony-laptop driver.
196 tristate "ThinkPad ACPI Laptop Extras"
199 select BACKLIGHT_LCD_SUPPORT
200 select BACKLIGHT_CLASS_DEVICE
208 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
209 support for Fn-Fx key combinations, Bluetooth control, video
210 output switching, ThinkLight control, UltraBay eject and more.
211 For more information about this driver see
212 <file:Documentation/laptops/thinkpad-acpi.txt> and
213 <http://ibm-acpi.sf.net/> .
215 This driver was formerly known as ibm-acpi.
217 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
219 config THINKPAD_ACPI_DEBUGFACILITIES
220 bool "Maintainer debug facilities"
221 depends on THINKPAD_ACPI
224 Enables extra stuff in the thinkpad-acpi which is completely useless
225 for normal use. Read the driver source to find out what it does.
227 Say N here, unless you were told by a kernel maintainer to do
230 config THINKPAD_ACPI_DEBUG
231 bool "Verbose debug mode"
232 depends on THINKPAD_ACPI
235 Enables extra debugging information, at the expense of a slightly
236 increase in driver size.
238 If you are not sure, say N here.
240 config THINKPAD_ACPI_UNSAFE_LEDS
241 bool "Allow control of important LEDs (unsafe)"
242 depends on THINKPAD_ACPI
245 Overriding LED state on ThinkPads can mask important
246 firmware alerts (like critical battery condition), or misled
247 the user into damaging the hardware (undocking or ejecting
248 the bay while buses are still active), etc.
250 LED control on the ThinkPad is write-only (with very few
251 exceptions on very ancient models), which makes it
252 impossible to know beforehand if important information will
253 be lost when one changes LED state.
255 Users that know what they are doing can enable this option
256 and the driver will allow control of every LED, including
257 the ones on the dock stations.
259 Never enable this option on a distribution kernel.
261 Say N here, unless you are building a kernel for your own
262 use, and need to control the important firmware LEDs.
264 config THINKPAD_ACPI_DOCK
265 bool "Legacy Docking Station Support"
266 depends on THINKPAD_ACPI
267 depends on ACPI_DOCK=n
270 Allows the thinkpad_acpi driver to handle docking station events.
271 This support was made obsolete by the generic ACPI docking station
272 support (CONFIG_ACPI_DOCK). It will allow locking and removing the
273 laptop from the docking station, but will not properly connect PCI
276 If you are not sure, say N here.
278 config THINKPAD_ACPI_BAY
279 bool "Legacy Removable Bay Support"
280 depends on THINKPAD_ACPI
283 Allows the thinkpad_acpi driver to handle removable bays. It will
284 electrically disable the device in the bay, and also generate
285 notifications when the bay lever is ejected or inserted.
287 If you are not sure, say Y here.
289 config THINKPAD_ACPI_VIDEO
290 bool "Video output control support"
291 depends on THINKPAD_ACPI
294 Allows the thinkpad_acpi driver to provide an interface to control
295 the various video output ports.
297 This feature often won't work well, depending on ThinkPad model,
298 display state, video output devices in use, whether there is a X
299 server running, phase of the moon, and the current mood of
300 Schroedinger's cat. If you can use X.org's RandR to control
301 your ThinkPad's video output ports instead of this feature,
302 don't think twice: do it and say N here to save some memory.
304 If you are not sure, say Y here.
306 config THINKPAD_ACPI_HOTKEY_POLL
307 bool "Support NVRAM polling for hot keys"
308 depends on THINKPAD_ACPI
311 Some thinkpad models benefit from NVRAM polling to detect a few of
312 the hot key press events. If you know your ThinkPad model does not
313 need to do NVRAM polling to support any of the hot keys you use,
314 unselecting this option will save about 1kB of memory.
316 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
317 unlikely to need NVRAM polling in their latest BIOS versions.
319 NVRAM polling can detect at most the following keys: ThinkPad/Access
320 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
321 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
323 If you are not sure, say Y here. The driver enables polling only if
324 it is strictly necessary to do so.
327 tristate "Thermal Management driver for Intel menlow platform"
328 depends on ACPI_THERMAL
331 ACPI thermal management enhancement driver on
332 Intel Menlow platform.
337 tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
340 depends on EXPERIMENTAL
341 select BACKLIGHT_CLASS_DEVICE
345 This driver supports the Fn-Fx keys on Eee PC laptops.
346 It also adds the ability to switch camera/wlan on/off.
348 If you have an Eee PC laptop, say Y or M here.
355 This driver adds support for the ACPI-WMI (Windows Management
356 Instrumentation) mapper device (PNP0C14) found on some systems.
358 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
359 ACPI firmware to userspace - this is done through various vendor
360 defined methods and data blocks in a PNP0C14 device, which are then
361 made available for userspace to call.
363 The implementation of this in Linux currently only exposes this to
364 other kernel space drivers.
366 This driver is a required dependency to build the firmware specific
367 drivers needed on many machines, including Acer and HP laptops.
369 It is safe to enable this driver even if your DSDT doesn't define
370 any ACPI-WMI devices.
373 tristate "ASUS/Medion Laptop Extras"
375 select BACKLIGHT_CLASS_DEVICE
377 This driver provides support for extra features of ACPI-compatible
378 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
379 support some Medion laptops (such as 9675 for example). It makes all
380 the extra buttons generate standard ACPI events that go through
381 /proc/acpi/events, and (on some models) adds support for changing the
382 display brightness and output, switching the LCD backlight on and off,
383 and most importantly, allows you to blink those fancy LEDs intended
384 for reporting mail and wireless status.
386 Note: display switching code is currently considered EXPERIMENTAL,
387 toying with these values may even lock your machine.
389 All settings are changed via /proc/acpi/asus directory entries. Owner
390 and group for these entries can be set with asus_uid and asus_gid
393 More information and a userspace daemon for handling the extra buttons
394 at <http://sourceforge.net/projects/acpi4asus/>.
396 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
397 driver is still under development, so if your laptop is unsupported or
398 something works not quite as expected, please use the mailing list
399 available on the above page (acpi4asus-user@lists.sourceforge.net).
401 NOTE: This driver is deprecated and will probably be removed soon,
402 use asus-laptop instead.
405 tristate "Toshiba Laptop Extras"
411 select BACKLIGHT_CLASS_DEVICE
413 This driver adds support for access to certain system settings
414 on "legacy free" Toshiba laptops. These laptops can be recognized by
415 their lack of a BIOS setup menu and APM support.
417 On these machines, all system configuration is handled through the
418 ACPI. This driver is required for access to controls not covered
419 by the general ACPI drivers, such as LCD brightness, video output,
422 This driver differs from the non-ACPI Toshiba laptop driver (located
423 under "Processor type and features") in several aspects.
424 Configuration is accessed by reading and writing text files in the
425 /proc tree instead of by program interface to /dev. Furthermore, no
426 power management functions are exposed, as those are handled by the
427 general ACPI drivers.
429 More information about this driver is available at
430 <http://memebeam.org/toys/ToshibaAcpiDriver>.
