65 This is the new Linux driver for Asus laptops. It may also support some
66 MEDION, JVC or VICTOR laptops. It makes all the extra buttons generate
67 standard ACPI events and input events. It also adds
68 support for video output switching, LCD backlight control, Bluetooth and
69 Wlan control, and most importantly, allows you to blink those fancy LEDs.
71 For more information and a userspace daemon for handling the extra
72 buttons see <http://acpi4asus.sf.net>.

100 config FUJITSU_LAPTOP
101 tristate "Fujitsu Laptop Extras"
104 depends on BACKLIGHT_CLASS_DEVICE
105 depends on LEDS_CLASS || LEDS_CLASS=n
107 This is a driver for laptops built by Fujitsu:
109 * P2xxx/P5xxx/S6xxx/S7xxx series Lifebooks
110 * Possibly other Fujitsu laptop models
111 * Tested with S6410 and S7020
113 It adds support for LCD brightness control and some hotkeys.
115 If you have a Fujitsu laptop, say Y or M here.
117 config FUJITSU_LAPTOP_DEBUG
118 bool "Verbose debug mode for Fujitsu Laptop Extras"
119 depends on FUJITSU_LAPTOP
122 Enables extra debug output from the fujitsu extras driver, at the
123 expense of a slight increase in driver size.
125 If you are not sure, say N here.
128 tristate "HP Compaq TC1100 Tablet WMI Extras (EXPERIMENTAL)"
130 depends on EXPERIMENTAL
134 This is a driver for the WMI extensions (wireless and bluetooth power
135 control) of the HP Compaq TC1100 tablet.
138 tristate "HP WMI extras"
141 depends on RFKILL || RFKILL = n
143 Say Y here if you want to support WMI-based hotkeys on HP laptops and
144 to read data from WMI such as docking or ambient light sensor state.

150 tristate "MSI Laptop Extras"
152 depends on BACKLIGHT_CLASS_DEVICE
154 depends on SERIO_I8042
156 This is a driver for laptops built by MSI (MICRO-STAR
159 MSI MegaBook S270 (MS-1013)
160 Cytron/TCM/Medion/Tchibo MD96100/SAM2000
162 It adds support for Bluetooth, WLAN and LCD brightness control.
164 More information about this driver is available at
165 <http://0pointer.de/lennart/tchibo.html>.
167 If you have an MSI S270 laptop, say Y or M here.
169 config PANASONIC_LAPTOP
170 tristate "Panasonic Laptop Extras"
171 depends on INPUT && ACPI
172 depends on BACKLIGHT_CLASS_DEVICE
174 This driver adds support for access to backlight control and hotkeys
175 on Panasonic Let's Note laptops.
177 If you have a Panasonic Let's note laptop (such as the R1(N variant),
178 R2, R3, R5, T2, W2 and Y2 series), say Y.
181 tristate "Compal Laptop Extras"
183 depends on BACKLIGHT_CLASS_DEVICE
186 depends on POWER_SUPPLY
188 This is a driver for laptops built by Compal:
195 It adds support for Bluetooth, WLAN and LCD brightness control.
197 If you have an Compal FL9x/IFL9x/FT00 laptop, say Y or M here.
200 tristate "Sony Laptop Extras"
202 select BACKLIGHT_CLASS_DEVICE
206 This mini-driver drives the SNC and SPIC devices present in the ACPI
207 BIOS of the Sony Vaio laptops.
209 It gives access to some extra laptop functionalities like Bluetooth,
210 screen brightness control, Fn keys and allows powering on/off some
213 Read <file:Documentation/laptops/sony-laptop.txt> for more information.
216 bool "Sonypi compatibility"
217 depends on SONY_LAPTOP
219 Build the sonypi driver compatibility code into the sony-laptop driver.
222 tristate "ThinkPad ACPI Laptop Extras"
225 depends on RFKILL || RFKILL = n
226 select BACKLIGHT_LCD_SUPPORT
227 select BACKLIGHT_CLASS_DEVICE
233 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
234 support for Fn-Fx key combinations, Bluetooth control, video
235 output switching, ThinkLight control, UltraBay eject and more.
236 For more information about this driver see
237 <file:Documentation/laptops/thinkpad-acpi.txt> and
238 <http://ibm-acpi.sf.net/> .
240 This driver was formerly known as ibm-acpi.
242 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
243 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
244 Note that if you want ThinkPad-ACPI to be built-in instead of
245 modular, ALSA and rfkill will also have to be built-in.
247 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
249 config THINKPAD_ACPI_ALSA_SUPPORT
250 bool "Console audio control ALSA interface"
251 depends on THINKPAD_ACPI
253 depends on SND = y || THINKPAD_ACPI = SND
256 Enables monitoring of the built-in console audio output control
257 (headphone and speakers), which is operated by the mute and (in
258 some ThinkPad models) volume hotkeys.
260 If this option is enabled, ThinkPad-ACPI will export an ALSA card
261 with a single read-only mixer control, which should be used for
262 on-screen-display feedback purposes by the Desktop Environment.
264 Optionally, the driver will also allow software control (the
265 ALSA mixer will be made read-write). Please refer to the driver
266 documentation for details.
268 All IBM models have both volume and mute control. Newer Lenovo
269 models only have mute control (the volume hotkeys are just normal
270 keys and volume control is done through the main HDA mixer).
272 config THINKPAD_ACPI_DEBUGFACILITIES
273 bool "Maintainer debug facilities"
274 depends on THINKPAD_ACPI
277 Enables extra stuff in the thinkpad-acpi which is completely useless
278 for normal use. Read the driver source to find out what it does.
280 Say N here, unless you were told by a kernel maintainer to do
283 config THINKPAD_ACPI_DEBUG
284 bool "Verbose debug mode"
285 depends on THINKPAD_ACPI
288 Enables extra debugging information, at the expense of a slightly
289 increase in driver size.
291 If you are not sure, say N here.
293 config THINKPAD_ACPI_UNSAFE_LEDS
294 bool "Allow control of important LEDs (unsafe)"
295 depends on THINKPAD_ACPI
298 Overriding LED state on ThinkPads can mask important
299 firmware alerts (like critical battery condition), or misled
300 the user into damaging the hardware (undocking or ejecting
301 the bay while buses are still active), etc.
303 LED control on the ThinkPad is write-only (with very few
304 exceptions on very ancient models), which makes it
305 impossible to know beforehand if important information will
306 be lost when one changes LED state.
308 Users that know what they are doing can enable this option
309 and the driver will allow control of every LED, including
310 the ones on the dock stations.
312 Never enable this option on a distribution kernel.
314 Say N here, unless you are building a kernel for your own
315 use, and need to control the important firmware LEDs.
317 config THINKPAD_ACPI_VIDEO
318 bool "Video output control support"
319 depends on THINKPAD_ACPI
322 Allows the thinkpad_acpi driver to provide an interface to control
323 the various video output ports.
325 This feature often won't work well, depending on ThinkPad model,
326 display state, video output devices in use, whether there is a X
327 server running, phase of the moon, and the current mood of
328 Schroedinger's cat. If you can use X.org's RandR to control
329 your ThinkPad's video output ports instead of this feature,
330 don't think twice: do it and say N here to save memory and avoid
331 bad interactions with X.org.
333 NOTE: access to this feature is limited to processes with the
334 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
335 where it interacts badly with X.org.
337 If you are not sure, say Y here but do try to check if you could
338 be using X.org RandR instead.
340 config THINKPAD_ACPI_HOTKEY_POLL
341 bool "Support NVRAM polling for hot keys"
342 depends on THINKPAD_ACPI
345 Some thinkpad models benefit from NVRAM polling to detect a few of
346 the hot key press events. If you know your ThinkPad model does not
347 need to do NVRAM polling to support any of the hot keys you use,
348 unselecting this option will save about 1kB of memory.
350 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
351 unlikely to need NVRAM polling in their latest BIOS versions.
353 NVRAM polling can detect at most the following keys: ThinkPad/Access
354 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
355 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
357 If you are not sure, say Y here. The driver enables polling only if
358 it is strictly necessary to do so.
361 tristate "Thermal Management driver for Intel menlow platform"
362 depends on ACPI_THERMAL
365 ACPI thermal management enhancement driver on
366 Intel Menlow platform.
371 tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
374 depends on EXPERIMENTAL
375 depends on RFKILL || RFKILL = n
376 depends on HOTPLUG_PCI
377 select BACKLIGHT_CLASS_DEVICE
381 select INPUT_SPARSEKMAP
383 This driver supports the Fn-Fx keys on Eee PC laptops.
385 It also gives access to some extra laptop functionalities like
386 Bluetooth, backlight and allows powering on/off some other
389 If you have an Eee PC laptop, say Y or M here.
392 tristate "Eee PC WMI Hotkey Driver (EXPERIMENTAL)"
395 depends on EXPERIMENTAL
396 depends on BACKLIGHT_CLASS_DEVICE
397 select INPUT_SPARSEKMAP
399 Say Y here if you want to support WMI-based hotkeys on Eee PC laptops.
401 To compile this driver as a module, choose M here: the module will
408 This driver adds support for the ACPI-WMI (Windows Management
409 Instrumentation) mapper device (PNP0C14) found on some systems.
411 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
412 ACPI firmware to userspace - this is done through various vendor
413 defined methods and data blocks in a PNP0C14 device, which are then
414 made available for userspace to call.
416 The implementation of this in Linux currently only exposes this to
417 other kernel space drivers.
419 This driver is a required dependency to build the firmware specific
420 drivers needed on many machines, including Acer and HP laptops.
422 It is safe to enable this driver even if your DSDT doesn't define
423 any ACPI-WMI devices.
426 tristate "MSI WMI extras"
429 depends on BACKLIGHT_CLASS_DEVICE
430 select INPUT_SPARSEKMAP
432 Say Y here if you want to support WMI-based hotkeys on MSI laptops.
434 To compile this driver as a module, choose M here: the module will
438 tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
440 select BACKLIGHT_CLASS_DEVICE
442 This driver provides support for extra features of ACPI-compatible
443 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
444 support some Medion laptops (such as 9675 for example). It makes all
445 the extra buttons generate standard ACPI events that go through
446 /proc/acpi/events, and (on some models) adds support for changing the
447 display brightness and output, switching the LCD backlight on and off,
448 and most importantly, allows you to blink those fancy LEDs intended
449 for reporting mail and wireless status.
451 Note: display switching code is currently considered EXPERIMENTAL,
452 toying with these values may even lock your machine.
454 All settings are changed via /proc/acpi/asus directory entries. Owner
455 and group for these entries can be set with asus_uid and asus_gid
458 More information and a userspace daemon for handling the extra buttons
459 at <http://acpi4asus.sf.net>.
461 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
462 driver is still under development, so if your laptop is unsupported or
463 something works not quite as expected, please use the mailing list
464 available on the above page (acpi4asus-user@lists.sourceforge.net).
466 NOTE: This driver is deprecated and will probably be removed soon,
467 use asus-laptop instead.
469 config TOPSTAR_LAPTOP
470 tristate "Topstar Laptop Extras"
474 This driver adds support for hotkeys found on Topstar laptops.
476 If you have a Topstar laptop, say Y or M here.
479 tristate "Toshiba Laptop Extras"
482 depends on RFKILL || RFKILL = n
484 select BACKLIGHT_CLASS_DEVICE
486 This driver adds support for access to certain system settings
487 on "legacy free" Toshiba laptops. These laptops can be recognized by
488 their lack of a BIOS setup menu and APM support.
490 On these machines, all system configuration is handled through the
491 ACPI. This driver is required for access to controls not covered
492 by the general ACPI drivers, such as LCD brightness, video output,
495 This driver differs from the non-ACPI Toshiba laptop driver (located
496 under "Processor type and features") in several aspects.
497 Configuration is accessed by reading and writing text files in the
498 /proc tree instead of by program interface to /dev. Furthermore, no
499 power management functions are exposed, as those are handled by the
500 general ACPI drivers.
502 More information about this driver is available at
503 <http://memebeam.org/toys/ToshibaAcpiDriver>.
505 If you have a legacy free Toshiba laptop (such as the Libretto L1
508 config TOSHIBA_BT_RFKILL
509 tristate "Toshiba Bluetooth RFKill switch support"
512 This driver adds support for Bluetooth events for the RFKill
513 switch on modern Toshiba laptops with full ACPI support and
516 This driver handles RFKill events for the TOS6205 Bluetooth,
517 and re-enables it when the switch is set back to the 'on'
520 If you have a modern Toshiba laptop with a Bluetooth and an
521 RFKill switch (such as the Portege R500), say Y.
524 tristate "CMPC Laptop Extras"
525 depends on X86 && ACPI
526 depends on RFKILL || RFKILL=n
528 select BACKLIGHT_CLASS_DEVICE
531 Support for Intel Classmate PC ACPI devices, including some
532 keys as input device, backlight device, tablet and accelerometer
536 bool "Intel SCU IPC Support"
540 IPC is used to bridge the communications between kernel and SCU on
541 some embedded Intel x86 platforms. This is not needed for PC-type
544 config GPIO_INTEL_PMIC
545 bool "Intel PMIC GPIO support"
546 depends on INTEL_SCU_IPC && GPIOLIB
548 Say Y here to support GPIO via the SCU IPC interface
549 on Intel MID platforms.
552 bool "Restricted Access Region Register Driver"
553 depends on PCI && X86_MRST
556 This driver allows other kernel drivers access to the
557 contents of the restricted access region control registers.
559 The restricted access region control registers
560 (rar_registers) are used to pass address and
561 locking information on restricted access regions
562 to other drivers that use restricted access regions.
564 The restricted access regions are regions of memory
565 on the Intel MID Platform that are not accessible to
566 the x86 processor, but are accessible to dedicated
567 processors on board peripheral devices.
569 The purpose of the restricted access regions is to
570 protect sensitive data from compromise by unauthorized
571 programs running on the x86 processor.
574 tristate "Intel Intelligent Power Sharing"
577 Intel Calpella platforms support dynamic power sharing between the
578 CPU and GPU, maximizing performance in a given TDP. This driver,
579 along with the CPU frequency and i915 drivers, provides that
580 functionality. If in doubt, say Y here; it will only load on
