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
169 This mini-driver drives the SNC and SPIC devices present in the ACPI
170 BIOS of the Sony Vaio laptops.
172 It gives access to some extra laptop functionalities like Bluetooth,
173 screen brightness control, Fn keys and allows powering on/off some
176 Read <file:Documentation/laptops/sony-laptop.txt> for more information.
179 bool "Sonypi compatibility"
180 depends on SONY_LAPTOP
182 Build the sonypi driver compatibility code into the sony-laptop driver.
185 tristate "ThinkPad ACPI Laptop Extras"
188 select BACKLIGHT_LCD_SUPPORT
189 select BACKLIGHT_CLASS_DEVICE
197 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
198 support for Fn-Fx key combinations, Bluetooth control, video
199 output switching, ThinkLight control, UltraBay eject and more.
200 For more information about this driver see
201 <file:Documentation/laptops/thinkpad-acpi.txt> and
202 <http://ibm-acpi.sf.net/> .
204 This driver was formerly known as ibm-acpi.
206 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
208 config THINKPAD_ACPI_DEBUGFACILITIES
209 bool "Maintainer debug facilities"
210 depends on THINKPAD_ACPI
213 Enables extra stuff in the thinkpad-acpi which is completely useless
214 for normal use. Read the driver source to find out what it does.
216 Say N here, unless you were told by a kernel maintainer to do
219 config THINKPAD_ACPI_DEBUG
220 bool "Verbose debug mode"
221 depends on THINKPAD_ACPI
224 Enables extra debugging information, at the expense of a slightly
225 increase in driver size.
227 If you are not sure, say N here.
229 config THINKPAD_ACPI_UNSAFE_LEDS
230 bool "Allow control of important LEDs (unsafe)"
231 depends on THINKPAD_ACPI
234 Overriding LED state on ThinkPads can mask important
235 firmware alerts (like critical battery condition), or misled
236 the user into damaging the hardware (undocking or ejecting
237 the bay while buses are still active), etc.
239 LED control on the ThinkPad is write-only (with very few
240 exceptions on very ancient models), which makes it
241 impossible to know beforehand if important information will
242 be lost when one changes LED state.
244 Users that know what they are doing can enable this option
245 and the driver will allow control of every LED, including
246 the ones on the dock stations.
248 Never enable this option on a distribution kernel.
250 Say N here, unless you are building a kernel for your own
251 use, and need to control the important firmware LEDs.
253 config THINKPAD_ACPI_DOCK
254 bool "Legacy Docking Station Support"
255 depends on THINKPAD_ACPI
256 depends on ACPI_DOCK=n
259 Allows the thinkpad_acpi driver to handle docking station events.
260 This support was made obsolete by the generic ACPI docking station
261 support (CONFIG_ACPI_DOCK). It will allow locking and removing the
262 laptop from the docking station, but will not properly connect PCI
265 If you are not sure, say N here.
267 config THINKPAD_ACPI_BAY
268 bool "Legacy Removable Bay Support"
269 depends on THINKPAD_ACPI
272 Allows the thinkpad_acpi driver to handle removable bays. It will
273 electrically disable the device in the bay, and also generate
274 notifications when the bay lever is ejected or inserted.
276 If you are not sure, say Y here.
278 config THINKPAD_ACPI_VIDEO
279 bool "Video output control support"
280 depends on THINKPAD_ACPI
283 Allows the thinkpad_acpi driver to provide an interface to control
284 the various video output ports.
286 This feature often won't work well, depending on ThinkPad model,
287 display state, video output devices in use, whether there is a X
288 server running, phase of the moon, and the current mood of
289 Schroedinger's cat. If you can use X.org's RandR to control
290 your ThinkPad's video output ports instead of this feature,
291 don't think twice: do it and say N here to save some memory.
293 If you are not sure, say Y here.
295 config THINKPAD_ACPI_HOTKEY_POLL
296 bool "Support NVRAM polling for hot keys"
297 depends on THINKPAD_ACPI
300 Some thinkpad models benefit from NVRAM polling to detect a few of
301 the hot key press events. If you know your ThinkPad model does not
302 need to do NVRAM polling to support any of the hot keys you use,
303 unselecting this option will save about 1kB of memory.
305 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
306 unlikely to need NVRAM polling in their latest BIOS versions.
308 NVRAM polling can detect at most the following keys: ThinkPad/Access
309 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
310 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
312 If you are not sure, say Y here. The driver enables polling only if
313 it is strictly necessary to do so.
316 tristate "Thermal Management driver for Intel menlow platform"
317 depends on ACPI_THERMAL
320 ACPI thermal management enhancement driver on
321 Intel Menlow platform.
326 tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
329 depends on EXPERIMENTAL
330 select BACKLIGHT_CLASS_DEVICE
334 This driver supports the Fn-Fx keys on Eee PC laptops.
335 It also adds the ability to switch camera/wlan on/off.
337 If you have an Eee PC laptop, say Y or M here.
344 This driver adds support for the ACPI-WMI (Windows Management
345 Instrumentation) mapper device (PNP0C14) found on some systems.
347 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
348 ACPI firmware to userspace - this is done through various vendor
349 defined methods and data blocks in a PNP0C14 device, which are then
350 made available for userspace to call.
352 The implementation of this in Linux currently only exposes this to
353 other kernel space drivers.
355 This driver is a required dependency to build the firmware specific
356 drivers needed on many machines, including Acer and HP laptops.
358 It is safe to enable this driver even if your DSDT doesn't define
359 any ACPI-WMI devices.
362 tristate "ASUS/Medion Laptop Extras"
364 select BACKLIGHT_CLASS_DEVICE
366 This driver provides support for extra features of ACPI-compatible
367 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
368 support some Medion laptops (such as 9675 for example). It makes all
369 the extra buttons generate standard ACPI events that go through
370 /proc/acpi/events, and (on some models) adds support for changing the
371 display brightness and output, switching the LCD backlight on and off,
372 and most importantly, allows you to blink those fancy LEDs intended
373 for reporting mail and wireless status.
375 Note: display switching code is currently considered EXPERIMENTAL,
376 toying with these values may even lock your machine.
378 All settings are changed via /proc/acpi/asus directory entries. Owner
379 and group for these entries can be set with asus_uid and asus_gid
382 More information and a userspace daemon for handling the extra buttons
383 at <http://sourceforge.net/projects/acpi4asus/>.
385 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
386 driver is still under development, so if your laptop is unsupported or
387 something works not quite as expected, please use the mailing list
388 available on the above page (acpi4asus-user@lists.sourceforge.net).
390 NOTE: This driver is deprecated and will probably be removed soon,
391 use asus-laptop instead.
394 tristate "Toshiba Laptop Extras"
400 select BACKLIGHT_CLASS_DEVICE
402 This driver adds support for access to certain system settings
403 on "legacy free" Toshiba laptops. These laptops can be recognized by
404 their lack of a BIOS setup menu and APM support.
406 On these machines, all system configuration is handled through the
407 ACPI. This driver is required for access to controls not covered
408 by the general ACPI drivers, such as LCD brightness, video output,
411 This driver differs from the non-ACPI Toshiba laptop driver (located
412 under "Processor type and features") in several aspects.
413 Configuration is accessed by reading and writing text files in the
414 /proc tree instead of by program interface to /dev. Furthermore, no
415 power management functions are exposed, as those are handled by the
416 general ACPI drivers.
418 More information about this driver is available at
419 <http://memebeam.org/toys/ToshibaAcpiDriver>.
