380 depends on RFKILL || RFKILL = n
381 depends on ACPI_VIDEO || ACPI_VIDEO = n
382 depends on BACKLIGHT_CLASS_DEVICE
388 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
389 support for Fn-Fx key combinations, Bluetooth control, video
390 output switching, ThinkLight control, UltraBay eject and more.
391 For more information about this driver see
392 <file:Documentation/laptops/thinkpad-acpi.txt> and
393 <http://ibm-acpi.sf.net/> .
395 This driver was formerly known as ibm-acpi.
397 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
398 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
399 Note that if you want ThinkPad-ACPI to be built-in instead of
400 modular, ALSA and rfkill will also have to be built-in.
402 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
404 config THINKPAD_ACPI_ALSA_SUPPORT
405 bool "Console audio control ALSA interface"
406 depends on THINKPAD_ACPI
408 depends on SND = y || THINKPAD_ACPI = SND
411 Enables monitoring of the built-in console audio output control
412 (headphone and speakers), which is operated by the mute and (in
413 some ThinkPad models) volume hotkeys.
415 If this option is enabled, ThinkPad-ACPI will export an ALSA card
416 with a single read-only mixer control, which should be used for
417 on-screen-display feedback purposes by the Desktop Environment.
419 Optionally, the driver will also allow software control (the
420 ALSA mixer will be made read-write). Please refer to the driver
421 documentation for details.
423 All IBM models have both volume and mute control. Newer Lenovo
424 models only have mute control (the volume hotkeys are just normal
425 keys and volume control is done through the main HDA mixer).

438 config THINKPAD_ACPI_DEBUG
439 bool "Verbose debug mode"
440 depends on THINKPAD_ACPI
443 Enables extra debugging information, at the expense of a slightly
444 increase in driver size.
446 If you are not sure, say N here.
448 config THINKPAD_ACPI_UNSAFE_LEDS
449 bool "Allow control of important LEDs (unsafe)"
450 depends on THINKPAD_ACPI
453 Overriding LED state on ThinkPads can mask important
454 firmware alerts (like critical battery condition), or misled
455 the user into damaging the hardware (undocking or ejecting
456 the bay while buses are still active), etc.
458 LED control on the ThinkPad is write-only (with very few
459 exceptions on very ancient models), which makes it
460 impossible to know beforehand if important information will
461 be lost when one changes LED state.
463 Users that know what they are doing can enable this option
464 and the driver will allow control of every LED, including
465 the ones on the dock stations.
467 Never enable this option on a distribution kernel.
469 Say N here, unless you are building a kernel for your own
470 use, and need to control the important firmware LEDs.
472 config THINKPAD_ACPI_VIDEO
473 bool "Video output control support"
474 depends on THINKPAD_ACPI
477 Allows the thinkpad_acpi driver to provide an interface to control
478 the various video output ports.
480 This feature often won't work well, depending on ThinkPad model,
481 display state, video output devices in use, whether there is a X
482 server running, phase of the moon, and the current mood of
483 Schroedinger's cat. If you can use X.org's RandR to control
484 your ThinkPad's video output ports instead of this feature,
485 don't think twice: do it and say N here to save memory and avoid
486 bad interactions with X.org.
488 NOTE: access to this feature is limited to processes with the
489 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
490 where it interacts badly with X.org.
492 If you are not sure, say Y here but do try to check if you could
493 be using X.org RandR instead.
495 config THINKPAD_ACPI_HOTKEY_POLL
496 bool "Support NVRAM polling for hot keys"
497 depends on THINKPAD_ACPI
500 Some thinkpad models benefit from NVRAM polling to detect a few of
501 the hot key press events. If you know your ThinkPad model does not
502 need to do NVRAM polling to support any of the hot keys you use,
503 unselecting this option will save about 1kB of memory.
505 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
506 unlikely to need NVRAM polling in their latest BIOS versions.
508 NVRAM polling can detect at most the following keys: ThinkPad/Access
509 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
510 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
512 If you are not sure, say Y here. The driver enables polling only if
513 it is strictly necessary to do so.
516 tristate "Thinkpad Hard Drive Active Protection System (hdaps)"
521 This driver provides support for the IBM Hard Drive Active Protection
522 System (hdaps), which provides an accelerometer and other misc. data.
523 ThinkPads starting with the R50, T41, and X40 are supported. The
524 accelerometer data is readable via sysfs.
526 This driver also provides an absolute input class device, allowing
527 the laptop to act as a pinball machine-esque joystick.
529 If your ThinkPad is not recognized by the driver, please update to latest
530 BIOS. This is especially the case for some R52 ThinkPads.
532 Say Y here if you have an applicable laptop and want to experience
533 the awesome power of hdaps.

623 Say Y or M here if you have an ASUS notebook with an airplane mode
626 If you choose to compile this driver as a module the module will be
627 called asus-wireless.
633 This driver adds support for the ACPI-WMI (Windows Management
634 Instrumentation) mapper device (PNP0C14) found on some systems.
636 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
637 ACPI firmware to userspace - this is done through various vendor
638 defined methods and data blocks in a PNP0C14 device, which are then
639 made available for userspace to call.
641 The implementation of this in Linux currently only exposes this to
642 other kernel space drivers.
644 This driver is a required dependency to build the firmware specific

692 On these machines, all system configuration is handled through the
693 ACPI. This driver is required for access to controls not covered
694 by the general ACPI drivers, such as LCD brightness, video output,
697 This driver differs from the non-ACPI Toshiba laptop driver (located
698 under "Processor type and features") in several aspects.
699 Configuration is accessed by reading and writing text files in the

885 sysfs on platforms that support this feature. System in PRTM will
886 not receive CPU-generated SMIs for recoverable errors. Use of this
887 feature without proper support may void your hardware warranty.
889 If the proper BIOS support is found the driver will load and create
890 /sys/devices/system/ibm_rtl/. The "state" variable will indicate
891 whether or not the BIOS is in PRTM.
892 state = 0 (BIOS SMIs on)
893 state = 1 (BIOS SMIs off)

973 This driver provides support for modifying paramaters on systems
974 equipped with Intel's Rapid Start Technology. When put in an ACPI
975 sleep state, these devices will wake after either a configured
976 timeout or when the system battery reaches a critical state,
977 automatically copying memory contents to disk. On resume, the
978 firmware will copy the memory contents back to RAM and resume the OS
981 config INTEL_SMARTCONNECT
982 tristate "Intel Smart Connect disabling driver"
985 Intel Smart Connect is a technology intended to permit devices to
986 update state by resuming for a short period of time at regular
987 intervals. If a user enables this functionality under Windows and
988 then reboots into Linux, the system may remain configured to resume
989 on suspend. In the absence of any userspace to support it, the system
990 will then remain awake until something triggers another suspend.
992 This driver checks to determine whether the device has Intel Smart
993 Connect enabled, and if so disables it.
996 tristate "pvpanic device support"
999 This driver provides support for the pvpanic device. pvpanic is

1072 depends on X86_64 && SCHED_MC_PRIO
1074 This driver reads maximum performance ratio of each CPU and set up
1075 the scheduler priority metrics. In this way scheduler can prefer
1076 CPU with higher performance to schedule tasks.
1077 This driver is only required when the system is not using Hardware
1078 P-States (HWP). In HWP mode, priority can be read from ACPI tables.
1081 bool "Tablets with Silead touchscreens"
1082 depends on ACPI && DMI && I2C=y && INPUT
1084 Certain ACPI based tablets with Silead touchscreens do not have
1085 enough data in ACPI tables for the touchscreen driver to handle
1086 the touchscreen properly, as OEMs expected the data to be baked
1087 into the tablet model specific version of the driver shipped
1088 with the OS-image for the device. This option supplies the missing
1089 information. Enable this for x86 tablets with Silead touchscreens.
