98 tristate "Fujitsu Laptop Extras"
101 depends on BACKLIGHT_CLASS_DEVICE
102 depends on LEDS_CLASS || LEDS_CLASS=n
104 This is a driver for laptops built by Fujitsu:
106 * P2xxx/P5xxx/S6xxx/S7xxx series Lifebooks
107 * Possibly other Fujitsu laptop models
108 * Tested with S6410 and S7020
110 It adds support for LCD brightness control and some hotkeys.
112 If you have a Fujitsu laptop, say Y or M here.
114 config FUJITSU_LAPTOP_DEBUG
115 bool "Verbose debug mode for Fujitsu Laptop Extras"
116 depends on FUJITSU_LAPTOP
119 Enables extra debug output from the fujitsu extras driver, at the
120 expense of a slight increase in driver size.
122 If you are not sure, say N here.
125 tristate "HP Compaq TC1100 Tablet WMI Extras (EXPERIMENTAL)"
127 depends on EXPERIMENTAL
131 This is a driver for the WMI extensions (wireless and bluetooth power
132 control) of the HP Compaq TC1100 tablet.
135 tristate "HP WMI extras"
138 depends on RFKILL || RFKILL = n
140 Say Y here if you want to support WMI-based hotkeys on HP laptops and
141 to read data from WMI such as docking or ambient light sensor state.
143 To compile this driver as a module, choose M here: the module will
147 tristate "MSI Laptop Extras"
149 depends on BACKLIGHT_CLASS_DEVICE
151 This is a driver for laptops built by MSI (MICRO-STAR
154 MSI MegaBook S270 (MS-1013)
155 Cytron/TCM/Medion/Tchibo MD96100/SAM2000
157 It adds support for Bluetooth, WLAN and LCD brightness control.
159 More information about this driver is available at
160 <http://0pointer.de/lennart/tchibo.html>.
162 If you have an MSI S270 laptop, say Y or M here.
164 config PANASONIC_LAPTOP
165 tristate "Panasonic Laptop Extras"
166 depends on INPUT && ACPI
167 depends on BACKLIGHT_CLASS_DEVICE
169 This driver adds support for access to backlight control and hotkeys
170 on Panasonic Let's Note laptops.
172 If you have a Panasonic Let's note laptop (such as the R1(N variant),
173 R2, R3, R5, T2, W2 and Y2 series), say Y.
176 tristate "Compal Laptop Extras"
178 depends on BACKLIGHT_CLASS_DEVICE
180 This is a driver for laptops built by Compal:
187 It adds support for Bluetooth, WLAN and LCD brightness control.
189 If you have an Compal FL9x/IFL9x/FT00 laptop, say Y or M here.
192 tristate "Sony Laptop Extras"
194 select BACKLIGHT_CLASS_DEVICE
198 This mini-driver drives the SNC and SPIC devices present in the ACPI
199 BIOS of the Sony Vaio laptops.
201 It gives access to some extra laptop functionalities like Bluetooth,
202 screen brightness control, Fn keys and allows powering on/off some
205 Read <file:Documentation/laptops/sony-laptop.txt> for more information.
208 bool "Sonypi compatibility"
209 depends on SONY_LAPTOP
211 Build the sonypi driver compatibility code into the sony-laptop driver.
214 tristate "ThinkPad ACPI Laptop Extras"
217 depends on RFKILL || RFKILL = n
218 select BACKLIGHT_LCD_SUPPORT
219 select BACKLIGHT_CLASS_DEVICE
225 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
226 support for Fn-Fx key combinations, Bluetooth control, video
227 output switching, ThinkLight control, UltraBay eject and more.
228 For more information about this driver see
229 <file:Documentation/laptops/thinkpad-acpi.txt> and
230 <http://ibm-acpi.sf.net/> .
232 This driver was formerly known as ibm-acpi.
234 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
236 config THINKPAD_ACPI_ALSA_SUPPORT
237 bool "Console audio control ALSA interface"
238 depends on THINKPAD_ACPI
240 depends on SND = y || THINKPAD_ACPI = SND
243 Enables monitoring of the built-in console audio output control
244 (headphone and speakers), which is operated by the mute and (in
245 some ThinkPad models) volume hotkeys.
247 If this option is enabled, ThinkPad-ACPI will export an ALSA card
248 with a single read-only mixer control, which should be used for
249 on-screen-display feedback purposes by the Desktop Environment.
251 Optionally, the driver will also allow software control (the
252 ALSA mixer will be made read-write). Please refer to the driver
253 documentation for details.
255 All IBM models have both volume and mute control. Newer Lenovo
256 models only have mute control (the volume hotkeys are just normal
257 keys and volume control is done through the main HDA mixer).
259 config THINKPAD_ACPI_DEBUGFACILITIES
260 bool "Maintainer debug facilities"
261 depends on THINKPAD_ACPI
264 Enables extra stuff in the thinkpad-acpi which is completely useless
265 for normal use. Read the driver source to find out what it does.
267 Say N here, unless you were told by a kernel maintainer to do
270 config THINKPAD_ACPI_DEBUG
271 bool "Verbose debug mode"
272 depends on THINKPAD_ACPI
275 Enables extra debugging information, at the expense of a slightly
276 increase in driver size.
278 If you are not sure, say N here.
280 config THINKPAD_ACPI_UNSAFE_LEDS
281 bool "Allow control of important LEDs (unsafe)"
282 depends on THINKPAD_ACPI
285 Overriding LED state on ThinkPads can mask important
286 firmware alerts (like critical battery condition), or misled
287 the user into damaging the hardware (undocking or ejecting
288 the bay while buses are still active), etc.
290 LED control on the ThinkPad is write-only (with very few
291 exceptions on very ancient models), which makes it
292 impossible to know beforehand if important information will
293 be lost when one changes LED state.
295 Users that know what they are doing can enable this option
296 and the driver will allow control of every LED, including
297 the ones on the dock stations.
299 Never enable this option on a distribution kernel.
301 Say N here, unless you are building a kernel for your own
302 use, and need to control the important firmware LEDs.
304 config THINKPAD_ACPI_VIDEO
305 bool "Video output control support"
306 depends on THINKPAD_ACPI
309 Allows the thinkpad_acpi driver to provide an interface to control
310 the various video output ports.
312 This feature often won't work well, depending on ThinkPad model,
313 display state, video output devices in use, whether there is a X
314 server running, phase of the moon, and the current mood of
315 Schroedinger's cat. If you can use X.org's RandR to control
316 your ThinkPad's video output ports instead of this feature,
317 don't think twice: do it and say N here to save memory and avoid
318 bad interactions with X.org.
320 NOTE: access to this feature is limited to processes with the
321 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
322 where it interacts badly with X.org.
324 If you are not sure, say Y here but do try to check if you could
325 be using X.org RandR instead.
327 config THINKPAD_ACPI_HOTKEY_POLL
328 bool "Support NVRAM polling for hot keys"
329 depends on THINKPAD_ACPI
332 Some thinkpad models benefit from NVRAM polling to detect a few of
333 the hot key press events. If you know your ThinkPad model does not
334 need to do NVRAM polling to support any of the hot keys you use,
335 unselecting this option will save about 1kB of memory.
337 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
338 unlikely to need NVRAM polling in their latest BIOS versions.
340 NVRAM polling can detect at most the following keys: ThinkPad/Access
341 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
342 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
344 If you are not sure, say Y here. The driver enables polling only if
345 it is strictly necessary to do so.
348 tristate "Thermal Management driver for Intel menlow platform"
349 depends on ACPI_THERMAL
352 ACPI thermal management enhancement driver on
353 Intel Menlow platform.
358 tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
361 depends on EXPERIMENTAL
362 depends on RFKILL || RFKILL = n
363 depends on HOTPLUG_PCI
364 select BACKLIGHT_CLASS_DEVICE
367 This driver supports the Fn-Fx keys on Eee PC laptops.
369 It also gives access to some extra laptop functionalities like
370 Bluetooth, backlight and allows powering on/off some other
373 If you have an Eee PC laptop, say Y or M here.
380 This driver adds support for the ACPI-WMI (Windows Management
381 Instrumentation) mapper device (PNP0C14) found on some systems.
383 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
384 ACPI firmware to userspace - this is done through various vendor
385 defined methods and data blocks in a PNP0C14 device, which are then
386 made available for userspace to call.
388 The implementation of this in Linux currently only exposes this to
389 other kernel space drivers.
391 This driver is a required dependency to build the firmware specific
392 drivers needed on many machines, including Acer and HP laptops.
394 It is safe to enable this driver even if your DSDT doesn't define
395 any ACPI-WMI devices.
398 tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
400 select BACKLIGHT_CLASS_DEVICE
402 This driver provides support for extra features of ACPI-compatible
403 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
404 support some Medion laptops (such as 9675 for example). It makes all
405 the extra buttons generate standard ACPI events that go through
406 /proc/acpi/events, and (on some models) adds support for changing the
407 display brightness and output, switching the LCD backlight on and off,
408 and most importantly, allows you to blink those fancy LEDs intended
409 for reporting mail and wireless status.
411 Note: display switching code is currently considered EXPERIMENTAL,
412 toying with these values may even lock your machine.
414 All settings are changed via /proc/acpi/asus directory entries. Owner
415 and group for these entries can be set with asus_uid and asus_gid
418 More information and a userspace daemon for handling the extra buttons
419 at <http://acpi4asus.sf.net>.
421 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
422 driver is still under development, so if your laptop is unsupported or
423 something works not quite as expected, please use the mailing list
424 available on the above page (acpi4asus-user@lists.sourceforge.net).
426 NOTE: This driver is deprecated and will probably be removed soon,
427 use asus-laptop instead.
429 config TOPSTAR_LAPTOP
430 tristate "Topstar Laptop Extras"
434 This driver adds support for hotkeys found on Topstar laptops.
436 If you have a Topstar laptop, say Y or M here.
439 tristate "Toshiba Laptop Extras"
442 depends on RFKILL || RFKILL = n
444 select BACKLIGHT_CLASS_DEVICE
446 This driver adds support for access to certain system settings
447 on "legacy free" Toshiba laptops. These laptops can be recognized by
448 their lack of a BIOS setup menu and APM support.
450 On these machines, all system configuration is handled through the
451 ACPI. This driver is required for access to controls not covered
452 by the general ACPI drivers, such as LCD brightness, video output,
455 This driver differs from the non-ACPI Toshiba laptop driver (located
456 under "Processor type and features") in several aspects.
457 Configuration is accessed by reading and writing text files in the
458 /proc tree instead of by program interface to /dev. Furthermore, no
459 power management functions are exposed, as those are handled by the
460 general ACPI drivers.
462 More information about this driver is available at
463 <http://memebeam.org/toys/ToshibaAcpiDriver>.
