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.
117 tristate "HP WMI extras"

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 depends on RFKILL || RFKILL = n
200 select BACKLIGHT_LCD_SUPPORT
201 select BACKLIGHT_CLASS_DEVICE
207 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
208 support for Fn-Fx key combinations, Bluetooth control, video
209 output switching, ThinkLight control, UltraBay eject and more.
210 For more information about this driver see
211 <file:Documentation/laptops/thinkpad-acpi.txt> and
212 <http://ibm-acpi.sf.net/> .
214 This driver was formerly known as ibm-acpi.
216 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
218 config THINKPAD_ACPI_DEBUGFACILITIES
219 bool "Maintainer debug facilities"
220 depends on THINKPAD_ACPI
223 Enables extra stuff in the thinkpad-acpi which is completely useless
224 for normal use. Read the driver source to find out what it does.
226 Say N here, unless you were told by a kernel maintainer to do
229 config THINKPAD_ACPI_DEBUG
230 bool "Verbose debug mode"
231 depends on THINKPAD_ACPI
234 Enables extra debugging information, at the expense of a slightly
235 increase in driver size.
237 If you are not sure, say N here.
239 config THINKPAD_ACPI_UNSAFE_LEDS
240 bool "Allow control of important LEDs (unsafe)"
241 depends on THINKPAD_ACPI
244 Overriding LED state on ThinkPads can mask important
245 firmware alerts (like critical battery condition), or misled
246 the user into damaging the hardware (undocking or ejecting
247 the bay while buses are still active), etc.
249 LED control on the ThinkPad is write-only (with very few
250 exceptions on very ancient models), which makes it
251 impossible to know beforehand if important information will
252 be lost when one changes LED state.
254 Users that know what they are doing can enable this option
255 and the driver will allow control of every LED, including
256 the ones on the dock stations.
258 Never enable this option on a distribution kernel.
260 Say N here, unless you are building a kernel for your own
261 use, and need to control the important firmware LEDs.
263 config THINKPAD_ACPI_DOCK
264 bool "Legacy Docking Station Support"
265 depends on THINKPAD_ACPI
266 depends on ACPI_DOCK=n
269 Allows the thinkpad_acpi driver to handle docking station events.
270 This support was made obsolete by the generic ACPI docking station
271 support (CONFIG_ACPI_DOCK). It will allow locking and removing the
272 laptop from the docking station, but will not properly connect PCI
275 If you are not sure, say N here.
277 config THINKPAD_ACPI_BAY
278 bool "Legacy Removable Bay Support"
279 depends on THINKPAD_ACPI
282 Allows the thinkpad_acpi driver to handle removable bays. It will
283 electrically disable the device in the bay, and also generate
284 notifications when the bay lever is ejected or inserted.
286 If you are not sure, say Y here.
288 config THINKPAD_ACPI_VIDEO
289 bool "Video output control support"
290 depends on THINKPAD_ACPI
293 Allows the thinkpad_acpi driver to provide an interface to control
294 the various video output ports.
296 This feature often won't work well, depending on ThinkPad model,
297 display state, video output devices in use, whether there is a X
298 server running, phase of the moon, and the current mood of
299 Schroedinger's cat. If you can use X.org's RandR to control
300 your ThinkPad's video output ports instead of this feature,
301 don't think twice: do it and say N here to save some memory.
303 If you are not sure, say Y here.
305 config THINKPAD_ACPI_HOTKEY_POLL
306 bool "Support NVRAM polling for hot keys"
307 depends on THINKPAD_ACPI
310 Some thinkpad models benefit from NVRAM polling to detect a few of
311 the hot key press events. If you know your ThinkPad model does not
312 need to do NVRAM polling to support any of the hot keys you use,
313 unselecting this option will save about 1kB of memory.
315 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
316 unlikely to need NVRAM polling in their latest BIOS versions.
318 NVRAM polling can detect at most the following keys: ThinkPad/Access
319 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
320 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
322 If you are not sure, say Y here. The driver enables polling only if
323 it is strictly necessary to do so.
326 tristate "Thermal Management driver for Intel menlow platform"
327 depends on ACPI_THERMAL
330 ACPI thermal management enhancement driver on
331 Intel Menlow platform.
336 tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
339 depends on EXPERIMENTAL
340 depends on RFKILL || RFKILL = n
341 select BACKLIGHT_CLASS_DEVICE
344 This driver supports the Fn-Fx keys on Eee PC laptops.
345 It also adds the ability to switch camera/wlan on/off.
347 If you have an Eee PC laptop, say Y or M here.
354 This driver adds support for the ACPI-WMI (Windows Management
355 Instrumentation) mapper device (PNP0C14) found on some systems.
357 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
358 ACPI firmware to userspace - this is done through various vendor
359 defined methods and data blocks in a PNP0C14 device, which are then
360 made available for userspace to call.
362 The implementation of this in Linux currently only exposes this to
363 other kernel space drivers.
365 This driver is a required dependency to build the firmware specific
366 drivers needed on many machines, including Acer and HP laptops.
368 It is safe to enable this driver even if your DSDT doesn't define
369 any ACPI-WMI devices.
372 tristate "ASUS/Medion Laptop Extras"
374 select BACKLIGHT_CLASS_DEVICE
376 This driver provides support for extra features of ACPI-compatible
377 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
378 support some Medion laptops (such as 9675 for example). It makes all
379 the extra buttons generate standard ACPI events that go through
380 /proc/acpi/events, and (on some models) adds support for changing the
381 display brightness and output, switching the LCD backlight on and off,
382 and most importantly, allows you to blink those fancy LEDs intended
383 for reporting mail and wireless status.
385 Note: display switching code is currently considered EXPERIMENTAL,
386 toying with these values may even lock your machine.
388 All settings are changed via /proc/acpi/asus directory entries. Owner
389 and group for these entries can be set with asus_uid and asus_gid
392 More information and a userspace daemon for handling the extra buttons
393 at <http://sourceforge.net/projects/acpi4asus/>.
395 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
396 driver is still under development, so if your laptop is unsupported or
397 something works not quite as expected, please use the mailing list
398 available on the above page (acpi4asus-user@lists.sourceforge.net).
400 NOTE: This driver is deprecated and will probably be removed soon,
401 use asus-laptop instead.
404 tristate "Toshiba Laptop Extras"
407 depends on RFKILL || RFKILL = n
409 select BACKLIGHT_CLASS_DEVICE
411 This driver adds support for access to certain system settings
412 on "legacy free" Toshiba laptops. These laptops can be recognized by
413 their lack of a BIOS setup menu and APM support.
415 On these machines, all system configuration is handled through the
416 ACPI. This driver is required for access to controls not covered
417 by the general ACPI drivers, such as LCD brightness, video output,
420 This driver differs from the non-ACPI Toshiba laptop driver (located
421 under "Processor type and features") in several aspects.
422 Configuration is accessed by reading and writing text files in the
423 /proc tree instead of by program interface to /dev. Furthermore, no
424 power management functions are exposed, as those are handled by the
425 general ACPI drivers.
427 More information about this driver is available at
428 <http://memebeam.org/toys/ToshibaAcpiDriver>.
