121 config FUJITSU_LAPTOP_DEBUG
122 bool "Verbose debug mode for Fujitsu Laptop Extras"
123 depends on FUJITSU_LAPTOP
126 Enables extra debug output from the fujitsu extras driver, at the
127 expense of a slight increase in driver size.
129 If you are not sure, say N here.
132 tristate "HP Compaq TC1100 Tablet WMI Extras (EXPERIMENTAL)"
134 depends on EXPERIMENTAL
138 This is a driver for the WMI extensions (wireless and bluetooth power
139 control) of the HP Compaq TC1100 tablet.
142 tristate "HP laptop accelerometer"

192 config PANASONIC_LAPTOP
193 tristate "Panasonic Laptop Extras"
194 depends on INPUT && ACPI
195 depends on BACKLIGHT_CLASS_DEVICE
196 select INPUT_SPARSEKMAP
198 This driver adds support for access to backlight control and hotkeys
199 on Panasonic Let's Note laptops.
201 If you have a Panasonic Let's note laptop (such as the R1(N variant),
202 R2, R3, R5, T2, W2 and Y2 series), say Y.

221 If you have an Compal FL9x/IFL9x/FT00 laptop, say Y or M here.
224 tristate "Sony Laptop Extras"
226 select BACKLIGHT_CLASS_DEVICE
230 This mini-driver drives the SNC and SPIC devices present in the ACPI
231 BIOS of the Sony Vaio laptops.
233 It gives access to some extra laptop functionalities like Bluetooth,
234 screen brightness control, Fn keys and allows powering on/off some
237 Read <file:Documentation/laptops/sony-laptop.txt> for more information.

245 config IDEAPAD_LAPTOP
246 tristate "Lenovo IdeaPad Laptop Extras"
248 depends on RFKILL && INPUT
249 select INPUT_SPARSEKMAP
251 This is a driver for the rfkill switches on Lenovo IdeaPad netbooks.
254 tristate "ThinkPad ACPI Laptop Extras"
257 depends on RFKILL || RFKILL = n
258 select BACKLIGHT_LCD_SUPPORT
259 select BACKLIGHT_CLASS_DEVICE
265 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
266 support for Fn-Fx key combinations, Bluetooth control, video
267 output switching, ThinkLight control, UltraBay eject and more.
268 For more information about this driver see
269 <file:Documentation/laptops/thinkpad-acpi.txt> and
270 <http://ibm-acpi.sf.net/> .
272 This driver was formerly known as ibm-acpi.
274 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
275 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
276 Note that if you want ThinkPad-ACPI to be built-in instead of
277 modular, ALSA and rfkill will also have to be built-in.
279 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
281 config THINKPAD_ACPI_ALSA_SUPPORT
282 bool "Console audio control ALSA interface"
283 depends on THINKPAD_ACPI
285 depends on SND = y || THINKPAD_ACPI = SND
288 Enables monitoring of the built-in console audio output control
289 (headphone and speakers), which is operated by the mute and (in
290 some ThinkPad models) volume hotkeys.
292 If this option is enabled, ThinkPad-ACPI will export an ALSA card
293 with a single read-only mixer control, which should be used for
294 on-screen-display feedback purposes by the Desktop Environment.
296 Optionally, the driver will also allow software control (the
297 ALSA mixer will be made read-write). Please refer to the driver
298 documentation for details.
300 All IBM models have both volume and mute control. Newer Lenovo
301 models only have mute control (the volume hotkeys are just normal
302 keys and volume control is done through the main HDA mixer).
304 config THINKPAD_ACPI_DEBUGFACILITIES
305 bool "Maintainer debug facilities"
306 depends on THINKPAD_ACPI
309 Enables extra stuff in the thinkpad-acpi which is completely useless
310 for normal use. Read the driver source to find out what it does.
312 Say N here, unless you were told by a kernel maintainer to do
315 config THINKPAD_ACPI_DEBUG
316 bool "Verbose debug mode"
317 depends on THINKPAD_ACPI
320 Enables extra debugging information, at the expense of a slightly
321 increase in driver size.
323 If you are not sure, say N here.
325 config THINKPAD_ACPI_UNSAFE_LEDS
326 bool "Allow control of important LEDs (unsafe)"
327 depends on THINKPAD_ACPI
330 Overriding LED state on ThinkPads can mask important
331 firmware alerts (like critical battery condition), or misled
332 the user into damaging the hardware (undocking or ejecting
333 the bay while buses are still active), etc.
335 LED control on the ThinkPad is write-only (with very few
336 exceptions on very ancient models), which makes it
337 impossible to know beforehand if important information will
338 be lost when one changes LED state.
340 Users that know what they are doing can enable this option
341 and the driver will allow control of every LED, including
342 the ones on the dock stations.
344 Never enable this option on a distribution kernel.
346 Say N here, unless you are building a kernel for your own
347 use, and need to control the important firmware LEDs.
349 config THINKPAD_ACPI_VIDEO
350 bool "Video output control support"
351 depends on THINKPAD_ACPI
354 Allows the thinkpad_acpi driver to provide an interface to control
355 the various video output ports.
357 This feature often won't work well, depending on ThinkPad model,
358 display state, video output devices in use, whether there is a X
359 server running, phase of the moon, and the current mood of
360 Schroedinger's cat. If you can use X.org's RandR to control
361 your ThinkPad's video output ports instead of this feature,
362 don't think twice: do it and say N here to save memory and avoid
363 bad interactions with X.org.
365 NOTE: access to this feature is limited to processes with the
366 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
367 where it interacts badly with X.org.
369 If you are not sure, say Y here but do try to check if you could
370 be using X.org RandR instead.
372 config THINKPAD_ACPI_HOTKEY_POLL
373 bool "Support NVRAM polling for hot keys"
374 depends on THINKPAD_ACPI
377 Some thinkpad models benefit from NVRAM polling to detect a few of
378 the hot key press events. If you know your ThinkPad model does not
379 need to do NVRAM polling to support any of the hot keys you use,
380 unselecting this option will save about 1kB of memory.
382 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
383 unlikely to need NVRAM polling in their latest BIOS versions.
385 NVRAM polling can detect at most the following keys: ThinkPad/Access
386 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
387 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
389 If you are not sure, say Y here. The driver enables polling only if
390 it is strictly necessary to do so.
393 tristate "Thinkpad Hard Drive Active Protection System (hdaps)"
394 depends on INPUT && X86
398 This driver provides support for the IBM Hard Drive Active Protection
399 System (hdaps), which provides an accelerometer and other misc. data.
400 ThinkPads starting with the R50, T41, and X40 are supported. The
401 accelerometer data is readable via sysfs.
403 This driver also provides an absolute input class device, allowing
404 the laptop to act as a pinball machine-esque joystick.
406 If your ThinkPad is not recognized by the driver, please update to latest
407 BIOS. This is especially the case for some R52 ThinkPads.
409 Say Y here if you have an applicable laptop and want to experience
410 the awesome power of hdaps.
413 tristate "Thermal Management driver for Intel menlow platform"
414 depends on ACPI_THERMAL
417 ACPI thermal management enhancement driver on
418 Intel Menlow platform.
423 tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
426 depends on EXPERIMENTAL
427 depends on RFKILL || RFKILL = n
428 depends on HOTPLUG_PCI
429 select BACKLIGHT_CLASS_DEVICE

435 This driver supports the Fn-Fx keys on Eee PC laptops.
437 It also gives access to some extra laptop functionalities like
438 Bluetooth, backlight and allows powering on/off some other

447 depends on EXPERIMENTAL
448 depends on BACKLIGHT_CLASS_DEVICE
449 depends on RFKILL || RFKILL = n
450 select INPUT_SPARSEKMAP
454 Say Y here if you want to support WMI-based hotkeys on Eee PC laptops.
456 To compile this driver as a module, choose M here: the module will
463 This driver adds support for the ACPI-WMI (Windows Management
464 Instrumentation) mapper device (PNP0C14) found on some systems.
466 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
467 ACPI firmware to userspace - this is done through various vendor
468 defined methods and data blocks in a PNP0C14 device, which are then
469 made available for userspace to call.
471 The implementation of this in Linux currently only exposes this to
472 other kernel space drivers.
474 This driver is a required dependency to build the firmware specific
475 drivers needed on many machines, including Acer and HP laptops.
477 It is safe to enable this driver even if your DSDT doesn't define
478 any ACPI-WMI devices.
481 tristate "MSI WMI extras"
484 depends on BACKLIGHT_CLASS_DEVICE
485 select INPUT_SPARSEKMAP
487 Say Y here if you want to support WMI-based hotkeys on MSI laptops.
489 To compile this driver as a module, choose M here: the module will
493 tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
495 select BACKLIGHT_CLASS_DEVICE
497 This driver provides support for extra features of ACPI-compatible
498 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
499 support some Medion laptops (such as 9675 for example). It makes all
500 the extra buttons generate standard ACPI events that go through
501 /proc/acpi/events, and (on some models) adds support for changing the
502 display brightness and output, switching the LCD backlight on and off,
503 and most importantly, allows you to blink those fancy LEDs intended
504 for reporting mail and wireless status.
506 Note: display switching code is currently considered EXPERIMENTAL,
507 toying with these values may even lock your machine.
509 All settings are changed via /proc/acpi/asus directory entries. Owner
510 and group for these entries can be set with asus_uid and asus_gid
513 More information and a userspace daemon for handling the extra buttons
514 at <http://acpi4asus.sf.net>.
516 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
517 driver is still under development, so if your laptop is unsupported or
518 something works not quite as expected, please use the mailing list
519 available on the above page (acpi4asus-user@lists.sourceforge.net).
521 NOTE: This driver is deprecated and will probably be removed soon,
522 use asus-laptop instead.
524 config TOPSTAR_LAPTOP
525 tristate "Topstar Laptop Extras"
528 select INPUT_SPARSEKMAP
530 This driver adds support for hotkeys found on Topstar laptops.
532 If you have a Topstar laptop, say Y or M here.
535 tristate "Toshiba Laptop Extras"
539 depends on BACKLIGHT_CLASS_DEVICE
541 depends on RFKILL || RFKILL = n
543 select INPUT_SPARSEKMAP
545 This driver adds support for access to certain system settings
546 on "legacy free" Toshiba laptops. These laptops can be recognized by
547 their lack of a BIOS setup menu and APM support.
549 On these machines, all system configuration is handled through the
550 ACPI. This driver is required for access to controls not covered
551 by the general ACPI drivers, such as LCD brightness, video output,
554 This driver differs from the non-ACPI Toshiba laptop driver (located
555 under "Processor type and features") in several aspects.
556 Configuration is accessed by reading and writing text files in the
557 /proc tree instead of by program interface to /dev. Furthermore, no
558 power management functions are exposed, as those are handled by the
559 general ACPI drivers.
561 More information about this driver is available at
562 <http://memebeam.org/toys/ToshibaAcpiDriver>.
564 If you have a legacy free Toshiba laptop (such as the Libretto L1
567 config TOSHIBA_BT_RFKILL
568 tristate "Toshiba Bluetooth RFKill switch support"
571 This driver adds support for Bluetooth events for the RFKill
572 switch on modern Toshiba laptops with full ACPI support and
575 This driver handles RFKill events for the TOS6205 Bluetooth,
576 and re-enables it when the switch is set back to the 'on'
579 If you have a modern Toshiba laptop with a Bluetooth and an
580 RFKill switch (such as the Portege R500), say Y.
583 tristate "CMPC Laptop Extras"
584 depends on X86 && ACPI
585 depends on RFKILL || RFKILL=n
587 select BACKLIGHT_CLASS_DEVICE
590 Support for Intel Classmate PC ACPI devices, including some
591 keys as input device, backlight device, tablet and accelerometer
595 bool "Intel SCU IPC Support"
599 IPC is used to bridge the communications between kernel and SCU on
600 some embedded Intel x86 platforms. This is not needed for PC-type
603 config INTEL_SCU_IPC_UTIL
604 tristate "Intel SCU IPC utility driver"
605 depends on INTEL_SCU_IPC
608 The IPC Util driver provides an interface with the SCU enabling
609 low level access for debug work and updating the firmware. Say
610 N unless you will be doing this on an Intel MID platform.
612 config GPIO_INTEL_PMIC
613 bool "Intel PMIC GPIO support"
614 depends on INTEL_SCU_IPC && GPIOLIB
616 Say Y here to support GPIO via the SCU IPC interface
617 on Intel MID platforms.
620 bool "Restricted Access Region Register Driver"
621 depends on PCI && X86_MRST
624 This driver allows other kernel drivers access to the
625 contents of the restricted access region control registers.
627 The restricted access region control registers
628 (rar_registers) are used to pass address and
629 locking information on restricted access regions
630 to other drivers that use restricted access regions.
632 The restricted access regions are regions of memory
633 on the Intel MID Platform that are not accessible to
634 the x86 processor, but are accessible to dedicated
635 processors on board peripheral devices.
637 The purpose of the restricted access regions is to
638 protect sensitive data from compromise by unauthorized
639 programs running on the x86 processor.
642 tristate "Intel Intelligent Power Sharing"
645 Intel Calpella platforms support dynamic power sharing between the
646 CPU and GPU, maximizing performance in a given TDP. This driver,
647 along with the CPU frequency and i915 drivers, provides that
648 functionality. If in doubt, say Y here; it will only load on
652 tristate "Device driver to enable PRTL support"
653 depends on X86 && PCI
655 Enable support for IBM Premium Real Time Mode (PRTM).
656 This module will allow you the enter and exit PRTM in the BIOS via
657 sysfs on platforms that support this feature. System in PRTM will
658 not receive CPU-generated SMIs for recoverable errors. Use of this
659 feature without proper support may void your hardware warranty.
661 If the proper BIOS support is found the driver will load and create
662 /sys/devices/system/ibm_rtl/. The "state" variable will indicate
663 whether or not the BIOS is in PRTM.
664 state = 0 (BIOS SMIs on)
665 state = 1 (BIOS SMIs off)
668 tristate "OLPC XO-1 software RF kill switch"
672 Support for enabling/disabling the WLAN interface on the OLPC XO-1
676 tristate "OLPC XO-1.5 ebook switch"
677 depends on ACPI && INPUT
679 Support for the ebook switch on the OLPC XO-1.5 laptop.
681 This switch is triggered as the screen is rotated and folded down to
682 convert the device into ebook form.
