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

517 tristate "Eee PC WMI Driver (EXPERIMENTAL)"
520 This is a driver for newer Eee PC laptops. It adds extra features
521 like wireless radio and bluetooth control, leds, hotkeys, backlight...
523 For more informations, see
524 <file:Documentation/ABI/testing/sysfs-platform-asus-wmi>
526 If you have an ACPI-WMI compatible Eee PC laptop (>= 1000), say Y or M
533 This driver adds support for the ACPI-WMI (Windows Management
534 Instrumentation) mapper device (PNP0C14) found on some systems.
536 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
537 ACPI firmware to userspace - this is done through various vendor
538 defined methods and data blocks in a PNP0C14 device, which are then
539 made available for userspace to call.
541 The implementation of this in Linux currently only exposes this to
542 other kernel space drivers.
544 This driver is a required dependency to build the firmware specific
545 drivers needed on many machines, including Acer and HP laptops.
547 It is safe to enable this driver even if your DSDT doesn't define
548 any ACPI-WMI devices.
551 tristate "MSI WMI extras"
554 depends on BACKLIGHT_CLASS_DEVICE
555 select INPUT_SPARSEKMAP
557 Say Y here if you want to support WMI-based hotkeys on MSI laptops.
559 To compile this driver as a module, choose M here: the module will
563 tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
565 select BACKLIGHT_CLASS_DEVICE
567 This driver provides support for extra features of ACPI-compatible
568 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
569 support some Medion laptops (such as 9675 for example). It makes all
570 the extra buttons generate standard ACPI events that go through
571 /proc/acpi/events, and (on some models) adds support for changing the
572 display brightness and output, switching the LCD backlight on and off,
573 and most importantly, allows you to blink those fancy LEDs intended
574 for reporting mail and wireless status.
576 Note: display switching code is currently considered EXPERIMENTAL,
577 toying with these values may even lock your machine.
579 All settings are changed via /proc/acpi/asus directory entries. Owner
580 and group for these entries can be set with asus_uid and asus_gid
583 More information and a userspace daemon for handling the extra buttons
584 at <http://acpi4asus.sf.net>.
586 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
587 driver is still under development, so if your laptop is unsupported or
588 something works not quite as expected, please use the mailing list
589 available on the above page (acpi4asus-user@lists.sourceforge.net).
591 NOTE: This driver is deprecated and will probably be removed soon,
592 use asus-laptop instead.
594 config TOPSTAR_LAPTOP
595 tristate "Topstar Laptop Extras"
598 select INPUT_SPARSEKMAP
600 This driver adds support for hotkeys found on Topstar laptops.
602 If you have a Topstar laptop, say Y or M here.
605 tristate "Toshiba Laptop Extras"
609 depends on BACKLIGHT_CLASS_DEVICE
611 depends on RFKILL || RFKILL = n
613 select INPUT_SPARSEKMAP
615 This driver adds support for access to certain system settings
616 on "legacy free" Toshiba laptops. These laptops can be recognized by
617 their lack of a BIOS setup menu and APM support.
619 On these machines, all system configuration is handled through the
620 ACPI. This driver is required for access to controls not covered
621 by the general ACPI drivers, such as LCD brightness, video output,
624 This driver differs from the non-ACPI Toshiba laptop driver (located
625 under "Processor type and features") in several aspects.
626 Configuration is accessed by reading and writing text files in the
627 /proc tree instead of by program interface to /dev. Furthermore, no
628 power management functions are exposed, as those are handled by the
629 general ACPI drivers.
631 More information about this driver is available at

706 depends on PCI && X86_MRST
709 This driver allows other kernel drivers access to the
710 contents of the restricted access region control registers.
712 The restricted access region control registers
713 (rar_registers) are used to pass address and
714 locking information on restricted access regions
715 to other drivers that use restricted access regions.
717 The restricted access regions are regions of memory
718 on the Intel MID Platform that are not accessible to
719 the x86 processor, but are accessible to dedicated
720 processors on board peripheral devices.
722 The purpose of the restricted access regions is to
723 protect sensitive data from compromise by unauthorized
724 programs running on the x86 processor.
727 tristate "Intel Intelligent Power Sharing"
730 Intel Calpella platforms support dynamic power sharing between the
731 CPU and GPU, maximizing performance in a given TDP. This driver,

741 This module will allow you the enter and exit PRTM in the BIOS via
742 sysfs on platforms that support this feature. System in PRTM will
743 not receive CPU-generated SMIs for recoverable errors. Use of this
744 feature without proper support may void your hardware warranty.
746 If the proper BIOS support is found the driver will load and create
747 /sys/devices/system/ibm_rtl/. The "state" variable will indicate
748 whether or not the BIOS is in PRTM.
