84 If you have a Fujitsu laptop, say Y or M here.
86 config FUJITSU_LAPTOP_DEBUG
87 bool "Verbose debug mode for Fujitsu Laptop Extras"
88 depends on FUJITSU_LAPTOP
91 Enables extra debug output from the fujitsu extras driver, at the
92 expense of a slight increase in driver size.
94 If you are not sure, say N here.
97 tristate "HP Compaq TC1100 Tablet WMI Extras (EXPERIMENTAL)"
99 depends on EXPERIMENTAL
103 This is a driver for the WMI extensions (wireless and bluetooth power
104 control) of the HP Compaq TC1100 tablet.

119 tristate "MSI Laptop Extras"
121 depends on BACKLIGHT_CLASS_DEVICE
123 This is a driver for laptops built by MSI (MICRO-STAR
126 MSI MegaBook S270 (MS-1013)
127 Cytron/TCM/Medion/Tchibo MD96100/SAM2000

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