112 * Tested with S6410 and S7020
114 It adds support for LCD brightness control and some hotkeys.
116 If you have a Fujitsu laptop, say Y or M here.
118 config FUJITSU_LAPTOP_DEBUG
119 bool "Verbose debug mode for Fujitsu Laptop Extras"
120 depends on FUJITSU_LAPTOP
123 Enables extra debug output from the fujitsu extras driver, at the
124 expense of a slight increase in driver size.
126 If you are not sure, say N here.
129 tristate "HP Compaq TC1100 Tablet WMI Extras (EXPERIMENTAL)"
131 depends on EXPERIMENTAL
135 This is a driver for the WMI extensions (wireless and bluetooth power
136 control) of the HP Compaq TC1100 tablet.
139 tristate "HP WMI extras"
142 depends on RFKILL || RFKILL = n

151 tristate "MSI Laptop Extras"
153 depends on BACKLIGHT_CLASS_DEVICE
155 depends on SERIO_I8042
157 This is a driver for laptops built by MSI (MICRO-STAR
160 MSI MegaBook S270 (MS-1013)
161 Cytron/TCM/Medion/Tchibo MD96100/SAM2000

171 tristate "Panasonic Laptop Extras"
172 depends on INPUT && ACPI
173 depends on BACKLIGHT_CLASS_DEVICE
174 select INPUT_SPARSEKMAP
176 This driver adds support for access to backlight control and hotkeys
177 on Panasonic Let's Note laptops.
179 If you have a Panasonic Let's note laptop (such as the R1(N variant),
180 R2, R3, R5, T2, W2 and Y2 series), say Y.
183 tristate "Compal Laptop Extras"
185 depends on BACKLIGHT_CLASS_DEVICE
188 depends on POWER_SUPPLY
190 This is a driver for laptops built by Compal:
197 It adds support for Bluetooth, WLAN and LCD brightness control.
199 If you have an Compal FL9x/IFL9x/FT00 laptop, say Y or M here.
202 tristate "Sony Laptop Extras"
204 select BACKLIGHT_CLASS_DEVICE
208 This mini-driver drives the SNC and SPIC devices present in the ACPI
209 BIOS of the Sony Vaio laptops.
211 It gives access to some extra laptop functionalities like Bluetooth,
212 screen brightness control, Fn keys and allows powering on/off some
215 Read <file:Documentation/laptops/sony-laptop.txt> for more information.
218 bool "Sonypi compatibility"
219 depends on SONY_LAPTOP
221 Build the sonypi driver compatibility code into the sony-laptop driver.
224 tristate "Lenovo IdeaPad ACPI Laptop Extras"
228 This is a driver for the rfkill switches on Lenovo IdeaPad netbooks.
231 tristate "ThinkPad ACPI Laptop Extras"
234 depends on RFKILL || RFKILL = n
235 select BACKLIGHT_LCD_SUPPORT
236 select BACKLIGHT_CLASS_DEVICE
242 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
243 support for Fn-Fx key combinations, Bluetooth control, video
244 output switching, ThinkLight control, UltraBay eject and more.
245 For more information about this driver see
246 <file:Documentation/laptops/thinkpad-acpi.txt> and
247 <http://ibm-acpi.sf.net/> .
249 This driver was formerly known as ibm-acpi.
251 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
252 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
253 Note that if you want ThinkPad-ACPI to be built-in instead of
254 modular, ALSA and rfkill will also have to be built-in.
256 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
258 config THINKPAD_ACPI_ALSA_SUPPORT
259 bool "Console audio control ALSA interface"
260 depends on THINKPAD_ACPI
262 depends on SND = y || THINKPAD_ACPI = SND
265 Enables monitoring of the built-in console audio output control
266 (headphone and speakers), which is operated by the mute and (in
267 some ThinkPad models) volume hotkeys.
269 If this option is enabled, ThinkPad-ACPI will export an ALSA card
270 with a single read-only mixer control, which should be used for
271 on-screen-display feedback purposes by the Desktop Environment.
273 Optionally, the driver will also allow software control (the
274 ALSA mixer will be made read-write). Please refer to the driver
275 documentation for details.
277 All IBM models have both volume and mute control. Newer Lenovo
278 models only have mute control (the volume hotkeys are just normal
279 keys and volume control is done through the main HDA mixer).
281 config THINKPAD_ACPI_DEBUGFACILITIES
282 bool "Maintainer debug facilities"
283 depends on THINKPAD_ACPI
286 Enables extra stuff in the thinkpad-acpi which is completely useless
287 for normal use. Read the driver source to find out what it does.
289 Say N here, unless you were told by a kernel maintainer to do
292 config THINKPAD_ACPI_DEBUG
293 bool "Verbose debug mode"
294 depends on THINKPAD_ACPI
297 Enables extra debugging information, at the expense of a slightly
298 increase in driver size.
300 If you are not sure, say N here.
302 config THINKPAD_ACPI_UNSAFE_LEDS
303 bool "Allow control of important LEDs (unsafe)"
304 depends on THINKPAD_ACPI
307 Overriding LED state on ThinkPads can mask important
308 firmware alerts (like critical battery condition), or misled
309 the user into damaging the hardware (undocking or ejecting
310 the bay while buses are still active), etc.
312 LED control on the ThinkPad is write-only (with very few
313 exceptions on very ancient models), which makes it
314 impossible to know beforehand if important information will
315 be lost when one changes LED state.
317 Users that know what they are doing can enable this option
318 and the driver will allow control of every LED, including
319 the ones on the dock stations.
321 Never enable this option on a distribution kernel.
323 Say N here, unless you are building a kernel for your own
324 use, and need to control the important firmware LEDs.
326 config THINKPAD_ACPI_VIDEO
327 bool "Video output control support"
328 depends on THINKPAD_ACPI
331 Allows the thinkpad_acpi driver to provide an interface to control
332 the various video output ports.
334 This feature often won't work well, depending on ThinkPad model,
335 display state, video output devices in use, whether there is a X
336 server running, phase of the moon, and the current mood of
337 Schroedinger's cat. If you can use X.org's RandR to control
338 your ThinkPad's video output ports instead of this feature,
339 don't think twice: do it and say N here to save memory and avoid
340 bad interactions with X.org.
342 NOTE: access to this feature is limited to processes with the
343 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
344 where it interacts badly with X.org.
346 If you are not sure, say Y here but do try to check if you could
347 be using X.org RandR instead.
349 config THINKPAD_ACPI_HOTKEY_POLL
350 bool "Support NVRAM polling for hot keys"
351 depends on THINKPAD_ACPI
354 Some thinkpad models benefit from NVRAM polling to detect a few of
355 the hot key press events. If you know your ThinkPad model does not
356 need to do NVRAM polling to support any of the hot keys you use,
357 unselecting this option will save about 1kB of memory.
359 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
360 unlikely to need NVRAM polling in their latest BIOS versions.
362 NVRAM polling can detect at most the following keys: ThinkPad/Access
363 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
364 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
366 If you are not sure, say Y here. The driver enables polling only if
367 it is strictly necessary to do so.
370 tristate "Thermal Management driver for Intel menlow platform"
371 depends on ACPI_THERMAL
374 ACPI thermal management enhancement driver on
375 Intel Menlow platform.
380 tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
383 depends on EXPERIMENTAL
384 depends on RFKILL || RFKILL = n
385 depends on HOTPLUG_PCI
386 select BACKLIGHT_CLASS_DEVICE
390 select INPUT_SPARSEKMAP
392 This driver supports the Fn-Fx keys on Eee PC laptops.
394 It also gives access to some extra laptop functionalities like
395 Bluetooth, backlight and allows powering on/off some other
398 If you have an Eee PC laptop, say Y or M here.
401 tristate "Eee PC WMI Hotkey Driver (EXPERIMENTAL)"
404 depends on EXPERIMENTAL
405 depends on BACKLIGHT_CLASS_DEVICE
406 select INPUT_SPARSEKMAP
408 Say Y here if you want to support WMI-based hotkeys on Eee PC laptops.
410 To compile this driver as a module, choose M here: the module will
417 This driver adds support for the ACPI-WMI (Windows Management
418 Instrumentation) mapper device (PNP0C14) found on some systems.
420 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
421 ACPI firmware to userspace - this is done through various vendor
422 defined methods and data blocks in a PNP0C14 device, which are then
423 made available for userspace to call.
425 The implementation of this in Linux currently only exposes this to
426 other kernel space drivers.
428 This driver is a required dependency to build the firmware specific
429 drivers needed on many machines, including Acer and HP laptops.
431 It is safe to enable this driver even if your DSDT doesn't define
432 any ACPI-WMI devices.
435 tristate "MSI WMI extras"
438 depends on BACKLIGHT_CLASS_DEVICE
439 select INPUT_SPARSEKMAP
441 Say Y here if you want to support WMI-based hotkeys on MSI laptops.
443 To compile this driver as a module, choose M here: the module will
447 tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
449 select BACKLIGHT_CLASS_DEVICE
451 This driver provides support for extra features of ACPI-compatible
452 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
453 support some Medion laptops (such as 9675 for example). It makes all
454 the extra buttons generate standard ACPI events that go through
455 /proc/acpi/events, and (on some models) adds support for changing the
456 display brightness and output, switching the LCD backlight on and off,
457 and most importantly, allows you to blink those fancy LEDs intended
458 for reporting mail and wireless status.
460 Note: display switching code is currently considered EXPERIMENTAL,
461 toying with these values may even lock your machine.
463 All settings are changed via /proc/acpi/asus directory entries. Owner
464 and group for these entries can be set with asus_uid and asus_gid
467 More information and a userspace daemon for handling the extra buttons
468 at <http://acpi4asus.sf.net>.
470 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
471 driver is still under development, so if your laptop is unsupported or
472 something works not quite as expected, please use the mailing list
473 available on the above page (acpi4asus-user@lists.sourceforge.net).
475 NOTE: This driver is deprecated and will probably be removed soon,
476 use asus-laptop instead.
478 config TOPSTAR_LAPTOP
479 tristate "Topstar Laptop Extras"
482 select INPUT_SPARSEKMAP
484 This driver adds support for hotkeys found on Topstar laptops.
486 If you have a Topstar laptop, say Y or M here.
489 tristate "Toshiba Laptop Extras"
491 depends on LEDS_CLASS
493 depends on BACKLIGHT_CLASS_DEVICE
495 depends on RFKILL || RFKILL = n
498 This driver adds support for access to certain system settings
499 on "legacy free" Toshiba laptops. These laptops can be recognized by
500 their lack of a BIOS setup menu and APM support.
502 On these machines, all system configuration is handled through the
503 ACPI. This driver is required for access to controls not covered
504 by the general ACPI drivers, such as LCD brightness, video output,
507 This driver differs from the non-ACPI Toshiba laptop driver (located
508 under "Processor type and features") in several aspects.
509 Configuration is accessed by reading and writing text files in the
510 /proc tree instead of by program interface to /dev. Furthermore, no
511 power management functions are exposed, as those are handled by the
512 general ACPI drivers.
514 More information about this driver is available at
515 <http://memebeam.org/toys/ToshibaAcpiDriver>.
517 If you have a legacy free Toshiba laptop (such as the Libretto L1
520 config TOSHIBA_BT_RFKILL
521 tristate "Toshiba Bluetooth RFKill switch support"
524 This driver adds support for Bluetooth events for the RFKill
525 switch on modern Toshiba laptops with full ACPI support and
528 This driver handles RFKill events for the TOS6205 Bluetooth,
529 and re-enables it when the switch is set back to the 'on'
532 If you have a modern Toshiba laptop with a Bluetooth and an
533 RFKill switch (such as the Portege R500), say Y.
536 tristate "CMPC Laptop Extras"
537 depends on X86 && ACPI
538 depends on RFKILL || RFKILL=n
540 select BACKLIGHT_CLASS_DEVICE
543 Support for Intel Classmate PC ACPI devices, including some
544 keys as input device, backlight device, tablet and accelerometer
548 bool "Intel SCU IPC Support"
552 IPC is used to bridge the communications between kernel and SCU on
553 some embedded Intel x86 platforms. This is not needed for PC-type
556 config GPIO_INTEL_PMIC
557 bool "Intel PMIC GPIO support"
558 depends on INTEL_SCU_IPC && GPIOLIB
560 Say Y here to support GPIO via the SCU IPC interface
561 on Intel MID platforms.
564 bool "Restricted Access Region Register Driver"
565 depends on PCI && X86_MRST
568 This driver allows other kernel drivers access to the
569 contents of the restricted access region control registers.
571 The restricted access region control registers
572 (rar_registers) are used to pass address and
573 locking information on restricted access regions
574 to other drivers that use restricted access regions.
576 The restricted access regions are regions of memory
577 on the Intel MID Platform that are not accessible to
578 the x86 processor, but are accessible to dedicated
579 processors on board peripheral devices.
581 The purpose of the restricted access regions is to
582 protect sensitive data from compromise by unauthorized
583 programs running on the x86 processor.
586 tristate "Intel Intelligent Power Sharing"
589 Intel Calpella platforms support dynamic power sharing between the
590 CPU and GPU, maximizing performance in a given TDP. This driver,
591 along with the CPU frequency and i915 drivers, provides that
592 functionality. If in doubt, say Y here; it will only load on
