38 tristate "Asus Laptop Extras (EXPERIMENTAL)"
40 depends on EXPERIMENTAL && !ACPI_ASUS
43 select BACKLIGHT_CLASS_DEVICE
46 This is the new Linux driver for Asus laptops. It may also support some
47 MEDION, JVC or VICTOR laptops. It makes all the extra buttons generate
48 standard ACPI events that go through /proc/acpi/events. It also adds
49 support for video output switching, LCD backlight control, Bluetooth and
50 Wlan control, and most importantly, allows you to blink those fancy LEDs.
52 For more information and a userspace daemon for handling the extra
53 buttons see <http://acpi4asus.sf.net/>.
55 If you have an ACPI-compatible ASUS laptop, say Y or M here.
58 tristate "Dell Laptop Extras (EXPERIMENTAL)"
61 depends on EXPERIMENTAL
62 depends on BACKLIGHT_CLASS_DEVICE
64 depends on POWER_SUPPLY
67 This driver adds support for rfkill and backlight control to Dell
71 tristate "Fujitsu Laptop Extras"
74 depends on BACKLIGHT_CLASS_DEVICE
76 This is a driver for laptops built by Fujitsu:
78 * P2xxx/P5xxx/S6xxx/S7xxx series Lifebooks
79 * Possibly other Fujitsu laptop models
80 * Tested with S6410 and S7020
82 It adds support for LCD brightness control and some hotkeys.
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.
107 tristate "HP WMI extras"
112 Say Y here if you want to support WMI-based hotkeys on HP laptops and
113 to read data from WMI such as docking or ambient light sensor state.
115 To compile this driver as a module, choose M here: the module will
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
129 It adds support for Bluetooth, WLAN and LCD brightness control.
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 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
207 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
208 Note that if you want ThinkPad-ACPI to be built-in instead of
209 modular, ALSA and rfkill will also have to be built-in.
211 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
213 config THINKPAD_ACPI_ALSA_SUPPORT
214 bool "Console audio control ALSA interface"
215 depends on THINKPAD_ACPI
217 depends on SND = y || THINKPAD_ACPI = SND
220 Enables monitoring of the built-in console audio output control
221 (headphone and speakers), which is operated by the mute and (in
222 some ThinkPad models) volume hotkeys.
224 If this option is enabled, ThinkPad-ACPI will export an ALSA card
225 with a single read-only mixer control, which should be used for
226 on-screen-display feedback purposes by the Desktop Environment.
228 Optionally, the driver will also allow software control (the
229 ALSA mixer will be made read-write). Please refer to the driver
230 documentation for details.
232 All IBM models have both volume and mute control. Newer Lenovo
233 models only have mute control (the volume hotkeys are just normal
234 keys and volume control is done through the main HDA mixer).
236 config THINKPAD_ACPI_DEBUGFACILITIES
237 bool "Maintainer debug facilities"
238 depends on THINKPAD_ACPI
241 Enables extra stuff in the thinkpad-acpi which is completely useless
242 for normal use. Read the driver source to find out what it does.
244 Say N here, unless you were told by a kernel maintainer to do
247 config THINKPAD_ACPI_DEBUG
248 bool "Verbose debug mode"
249 depends on THINKPAD_ACPI
252 Enables extra debugging information, at the expense of a slightly
253 increase in driver size.
255 If you are not sure, say N here.
257 config THINKPAD_ACPI_UNSAFE_LEDS
258 bool "Allow control of important LEDs (unsafe)"
259 depends on THINKPAD_ACPI
262 Overriding LED state on ThinkPads can mask important
263 firmware alerts (like critical battery condition), or misled
264 the user into damaging the hardware (undocking or ejecting
265 the bay while buses are still active), etc.
267 LED control on the ThinkPad is write-only (with very few
268 exceptions on very ancient models), which makes it
269 impossible to know beforehand if important information will
270 be lost when one changes LED state.
272 Users that know what they are doing can enable this option
273 and the driver will allow control of every LED, including
274 the ones on the dock stations.
276 Never enable this option on a distribution kernel.
278 Say N here, unless you are building a kernel for your own
279 use, and need to control the important firmware LEDs.
281 config THINKPAD_ACPI_VIDEO
282 bool "Video output control support"
283 depends on THINKPAD_ACPI
286 Allows the thinkpad_acpi driver to provide an interface to control
287 the various video output ports.
289 This feature often won't work well, depending on ThinkPad model,
290 display state, video output devices in use, whether there is a X
291 server running, phase of the moon, and the current mood of
292 Schroedinger's cat. If you can use X.org's RandR to control
293 your ThinkPad's video output ports instead of this feature,
294 don't think twice: do it and say N here to save some memory.
296 If you are not sure, say Y here.
298 config THINKPAD_ACPI_HOTKEY_POLL
299 bool "Support NVRAM polling for hot keys"
300 depends on THINKPAD_ACPI
303 Some thinkpad models benefit from NVRAM polling to detect a few of
304 the hot key press events. If you know your ThinkPad model does not
305 need to do NVRAM polling to support any of the hot keys you use,
306 unselecting this option will save about 1kB of memory.
308 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
309 unlikely to need NVRAM polling in their latest BIOS versions.
311 NVRAM polling can detect at most the following keys: ThinkPad/Access
312 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
313 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
315 If you are not sure, say Y here. The driver enables polling only if
316 it is strictly necessary to do so.
319 tristate "Thermal Management driver for Intel menlow platform"
320 depends on ACPI_THERMAL
323 ACPI thermal management enhancement driver on
324 Intel Menlow platform.
329 tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
332 depends on EXPERIMENTAL
333 select BACKLIGHT_CLASS_DEVICE
337 This driver supports the Fn-Fx keys on Eee PC laptops.
338 It also adds the ability to switch camera/wlan on/off.
340 If you have an Eee PC laptop, say Y or M here.
347 This driver adds support for the ACPI-WMI (Windows Management
348 Instrumentation) mapper device (PNP0C14) found on some systems.
350 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
351 ACPI firmware to userspace - this is done through various vendor
352 defined methods and data blocks in a PNP0C14 device, which are then
353 made available for userspace to call.
355 The implementation of this in Linux currently only exposes this to
356 other kernel space drivers.
358 This driver is a required dependency to build the firmware specific
359 drivers needed on many machines, including Acer and HP laptops.
361 It is safe to enable this driver even if your DSDT doesn't define
362 any ACPI-WMI devices.
365 tristate "ASUS/Medion Laptop Extras"
367 select BACKLIGHT_CLASS_DEVICE
369 This driver provides support for extra features of ACPI-compatible
370 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
371 support some Medion laptops (such as 9675 for example). It makes all
372 the extra buttons generate standard ACPI events that go through
373 /proc/acpi/events, and (on some models) adds support for changing the
374 display brightness and output, switching the LCD backlight on and off,
375 and most importantly, allows you to blink those fancy LEDs intended
376 for reporting mail and wireless status.
378 Note: display switching code is currently considered EXPERIMENTAL,
379 toying with these values may even lock your machine.
381 All settings are changed via /proc/acpi/asus directory entries. Owner
382 and group for these entries can be set with asus_uid and asus_gid
385 More information and a userspace daemon for handling the extra buttons
386 at <http://sourceforge.net/projects/acpi4asus/>.
388 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
389 driver is still under development, so if your laptop is unsupported or
390 something works not quite as expected, please use the mailing list
391 available on the above page (acpi4asus-user@lists.sourceforge.net).
393 NOTE: This driver is deprecated and will probably be removed soon,
394 use asus-laptop instead.
397 tristate "Toshiba Laptop Extras"
403 select BACKLIGHT_CLASS_DEVICE
405 This driver adds support for access to certain system settings
406 on "legacy free" Toshiba laptops. These laptops can be recognized by
407 their lack of a BIOS setup menu and APM support.
409 On these machines, all system configuration is handled through the
410 ACPI. This driver is required for access to controls not covered
411 by the general ACPI drivers, such as LCD brightness, video output,
414 This driver differs from the non-ACPI Toshiba laptop driver (located
415 under "Processor type and features") in several aspects.
416 Configuration is accessed by reading and writing text files in the
417 /proc tree instead of by program interface to /dev. Furthermore, no
418 power management functions are exposed, as those are handled by the
419 general ACPI drivers.
421 More information about this driver is available at
422 <http://memebeam.org/toys/ToshibaAcpiDriver>.
