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.
117 tristate "HP WMI extras"

129 tristate "MSI Laptop Extras"
131 depends on BACKLIGHT_CLASS_DEVICE
133 This is a driver for laptops built by MSI (MICRO-STAR
136 MSI MegaBook S270 (MS-1013)
137 Cytron/TCM/Medion/Tchibo MD96100/SAM2000
139 It adds support for Bluetooth, WLAN and LCD brightness control.
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_ALSA_SUPPORT
220 bool "Console audio control ALSA interface"
221 depends on THINKPAD_ACPI
223 depends on SND = y || THINKPAD_ACPI = SND
226 Enables monitoring of the built-in console audio output control
227 (headphone and speakers), which is operated by the mute and (in
228 some ThinkPad models) volume hotkeys.
230 If this option is enabled, ThinkPad-ACPI will export an ALSA card
231 with a single read-only mixer control, which should be used for
232 on-screen-display feedback purposes by the Desktop Environment.
234 Optionally, the driver will also allow software control (the
235 ALSA mixer will be made read-write). Please refer to the driver
236 documentation for details.
238 All IBM models have both volume and mute control. Newer Lenovo
239 models only have mute control (the volume hotkeys are just normal
240 keys and volume control is done through the main HDA mixer).
242 config THINKPAD_ACPI_DEBUGFACILITIES
243 bool "Maintainer debug facilities"
244 depends on THINKPAD_ACPI
247 Enables extra stuff in the thinkpad-acpi which is completely useless
248 for normal use. Read the driver source to find out what it does.
250 Say N here, unless you were told by a kernel maintainer to do
253 config THINKPAD_ACPI_DEBUG
254 bool "Verbose debug mode"
255 depends on THINKPAD_ACPI
258 Enables extra debugging information, at the expense of a slightly
259 increase in driver size.
261 If you are not sure, say N here.
263 config THINKPAD_ACPI_UNSAFE_LEDS
264 bool "Allow control of important LEDs (unsafe)"
265 depends on THINKPAD_ACPI
268 Overriding LED state on ThinkPads can mask important
269 firmware alerts (like critical battery condition), or misled
270 the user into damaging the hardware (undocking or ejecting
271 the bay while buses are still active), etc.
273 LED control on the ThinkPad is write-only (with very few
274 exceptions on very ancient models), which makes it
275 impossible to know beforehand if important information will
276 be lost when one changes LED state.
278 Users that know what they are doing can enable this option
279 and the driver will allow control of every LED, including
280 the ones on the dock stations.
282 Never enable this option on a distribution kernel.
284 Say N here, unless you are building a kernel for your own
285 use, and need to control the important firmware LEDs.
287 config THINKPAD_ACPI_VIDEO
288 bool "Video output control support"
289 depends on THINKPAD_ACPI
292 Allows the thinkpad_acpi driver to provide an interface to control
293 the various video output ports.
295 This feature often won't work well, depending on ThinkPad model,
296 display state, video output devices in use, whether there is a X
297 server running, phase of the moon, and the current mood of
298 Schroedinger's cat. If you can use X.org's RandR to control
299 your ThinkPad's video output ports instead of this feature,
300 don't think twice: do it and say N here to save some memory.
302 If you are not sure, say Y here.
304 config THINKPAD_ACPI_HOTKEY_POLL
305 bool "Support NVRAM polling for hot keys"
306 depends on THINKPAD_ACPI
309 Some thinkpad models benefit from NVRAM polling to detect a few of
310 the hot key press events. If you know your ThinkPad model does not
311 need to do NVRAM polling to support any of the hot keys you use,
312 unselecting this option will save about 1kB of memory.
314 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
315 unlikely to need NVRAM polling in their latest BIOS versions.
317 NVRAM polling can detect at most the following keys: ThinkPad/Access
318 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
319 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
321 If you are not sure, say Y here. The driver enables polling only if
322 it is strictly necessary to do so.
325 tristate "Thermal Management driver for Intel menlow platform"
326 depends on ACPI_THERMAL
329 ACPI thermal management enhancement driver on
330 Intel Menlow platform.
335 tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
338 depends on EXPERIMENTAL
339 select BACKLIGHT_CLASS_DEVICE
343 This driver supports the Fn-Fx keys on Eee PC laptops.
344 It also adds the ability to switch camera/wlan on/off.
346 If you have an Eee PC laptop, say Y or M here.
353 This driver adds support for the ACPI-WMI (Windows Management
354 Instrumentation) mapper device (PNP0C14) found on some systems.
356 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
357 ACPI firmware to userspace - this is done through various vendor
358 defined methods and data blocks in a PNP0C14 device, which are then
359 made available for userspace to call.
361 The implementation of this in Linux currently only exposes this to
362 other kernel space drivers.
364 This driver is a required dependency to build the firmware specific
365 drivers needed on many machines, including Acer and HP laptops.
367 It is safe to enable this driver even if your DSDT doesn't define
368 any ACPI-WMI devices.
371 tristate "ASUS/Medion Laptop Extras"
373 select BACKLIGHT_CLASS_DEVICE
375 This driver provides support for extra features of ACPI-compatible
376 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
377 support some Medion laptops (such as 9675 for example). It makes all
378 the extra buttons generate standard ACPI events that go through
379 /proc/acpi/events, and (on some models) adds support for changing the
380 display brightness and output, switching the LCD backlight on and off,
381 and most importantly, allows you to blink those fancy LEDs intended
382 for reporting mail and wireless status.
384 Note: display switching code is currently considered EXPERIMENTAL,
385 toying with these values may even lock your machine.
387 All settings are changed via /proc/acpi/asus directory entries. Owner
388 and group for these entries can be set with asus_uid and asus_gid
391 More information and a userspace daemon for handling the extra buttons
392 at <http://sourceforge.net/projects/acpi4asus/>.
394 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
395 driver is still under development, so if your laptop is unsupported or
396 something works not quite as expected, please use the mailing list
397 available on the above page (acpi4asus-user@lists.sourceforge.net).
399 NOTE: This driver is deprecated and will probably be removed soon,
400 use asus-laptop instead.
403 tristate "Toshiba Laptop Extras"
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>.
