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"

146 tristate "MSI Laptop Extras"
148 depends on BACKLIGHT_CLASS_DEVICE
150 This is a driver for laptops built by MSI (MICRO-STAR
153 MSI MegaBook S270 (MS-1013)
154 Cytron/TCM/Medion/Tchibo MD96100/SAM2000
156 It adds support for Bluetooth, WLAN and LCD brightness control.
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_VIDEO
281 bool "Video output control support"
282 depends on THINKPAD_ACPI
285 Allows the thinkpad_acpi driver to provide an interface to control
286 the various video output ports.
288 This feature often won't work well, depending on ThinkPad model,
289 display state, video output devices in use, whether there is a X
290 server running, phase of the moon, and the current mood of
291 Schroedinger's cat. If you can use X.org's RandR to control
292 your ThinkPad's video output ports instead of this feature,
293 don't think twice: do it and say N here to save some memory.
295 If you are not sure, say Y here.
297 config THINKPAD_ACPI_HOTKEY_POLL
298 bool "Support NVRAM polling for hot keys"
299 depends on THINKPAD_ACPI
302 Some thinkpad models benefit from NVRAM polling to detect a few of
303 the hot key press events. If you know your ThinkPad model does not
304 need to do NVRAM polling to support any of the hot keys you use,
305 unselecting this option will save about 1kB of memory.
307 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
308 unlikely to need NVRAM polling in their latest BIOS versions.
310 NVRAM polling can detect at most the following keys: ThinkPad/Access
311 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
312 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
314 If you are not sure, say Y here. The driver enables polling only if
315 it is strictly necessary to do so.
318 tristate "Thermal Management driver for Intel menlow platform"
319 depends on ACPI_THERMAL
322 ACPI thermal management enhancement driver on
323 Intel Menlow platform.
328 tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
331 depends on EXPERIMENTAL
332 depends on RFKILL || RFKILL = n
333 depends on HOTPLUG_PCI
334 select BACKLIGHT_CLASS_DEVICE
337 This driver supports the Fn-Fx keys on Eee PC laptops.
339 It also gives access to some extra laptop functionalities like
340 Bluetooth, backlight and allows powering on/off some other
343 If you have an Eee PC laptop, say Y or M here.
350 This driver adds support for the ACPI-WMI (Windows Management
351 Instrumentation) mapper device (PNP0C14) found on some systems.
353 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
354 ACPI firmware to userspace - this is done through various vendor
355 defined methods and data blocks in a PNP0C14 device, which are then
356 made available for userspace to call.
358 The implementation of this in Linux currently only exposes this to
359 other kernel space drivers.
361 This driver is a required dependency to build the firmware specific
362 drivers needed on many machines, including Acer and HP laptops.
364 It is safe to enable this driver even if your DSDT doesn't define
365 any ACPI-WMI devices.
368 tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
370 select BACKLIGHT_CLASS_DEVICE
372 This driver provides support for extra features of ACPI-compatible
373 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
374 support some Medion laptops (such as 9675 for example). It makes all
375 the extra buttons generate standard ACPI events that go through
376 /proc/acpi/events, and (on some models) adds support for changing the
377 display brightness and output, switching the LCD backlight on and off,
378 and most importantly, allows you to blink those fancy LEDs intended
379 for reporting mail and wireless status.
381 Note: display switching code is currently considered EXPERIMENTAL,
382 toying with these values may even lock your machine.
384 All settings are changed via /proc/acpi/asus directory entries. Owner
385 and group for these entries can be set with asus_uid and asus_gid
388 More information and a userspace daemon for handling the extra buttons
389 at <http://acpi4asus.sf.net>.
391 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
392 driver is still under development, so if your laptop is unsupported or
393 something works not quite as expected, please use the mailing list
394 available on the above page (acpi4asus-user@lists.sourceforge.net).
396 NOTE: This driver is deprecated and will probably be removed soon,
397 use asus-laptop instead.
400 tristate "Toshiba Laptop Extras"
403 depends on RFKILL || RFKILL = n
405 select BACKLIGHT_CLASS_DEVICE
407 This driver adds support for access to certain system settings
408 on "legacy free" Toshiba laptops. These laptops can be recognized by
409 their lack of a BIOS setup menu and APM support.
411 On these machines, all system configuration is handled through the
412 ACPI. This driver is required for access to controls not covered
413 by the general ACPI drivers, such as LCD brightness, video output,
416 This driver differs from the non-ACPI Toshiba laptop driver (located
417 under "Processor type and features") in several aspects.
418 Configuration is accessed by reading and writing text files in the
419 /proc tree instead of by program interface to /dev. Furthermore, no
420 power management functions are exposed, as those are handled by the
421 general ACPI drivers.
423 More information about this driver is available at
424 <http://memebeam.org/toys/ToshibaAcpiDriver>.
