 230           This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
 231           support for Fn-Fx key combinations, Bluetooth control, video
 232           output switching, ThinkLight control, UltraBay eject and more.
 233           For more information about this driver see
 234           <file:Documentation/laptops/thinkpad-acpi.txt> and
 235           <http://ibm-acpi.sf.net/> .
 236
 237           This driver was formerly known as ibm-acpi.
 238
 239           Extra functionality will be available if the rfkill (CONFIG_RFKILL)
 240           and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
 241           Note that if you want ThinkPad-ACPI to be built-in instead of
 242           modular, ALSA and rfkill will also have to be built-in.

 254           (headphone and speakers), which is operated by the mute and (in
 255           some ThinkPad models) volume hotkeys.
 256
 257           If this option is enabled, ThinkPad-ACPI will export an ALSA card
 258           with a single read-only mixer control, which should be used for
 259           on-screen-display feedback purposes by the Desktop Environment.
 260
 261           Optionally, the driver will also allow software control (the
 262           ALSA mixer will be made read-write).  Please refer to the driver
 263           documentation for details.
 264
 265           All IBM models have both volume and mute control.  Newer Lenovo
 266           models only have mute control (the volume hotkeys are just normal
 267           keys and volume control is done through the main HDA mixer).

 295           Overriding LED state on ThinkPads can mask important

 297           the user into damaging the hardware (undocking or ejecting
 298           the bay while buses are still active), etc.
 299
 300           LED control on the ThinkPad is write-only (with very few
 301           exceptions on very ancient models), which makes it
 302           impossible to know beforehand if important information will
 303           be lost when one changes LED state.
 304
 305           Users that know what they are doing can enable this option
 306           and the driver will allow control of every LED, including
 307           the ones on the dock stations.
 308
 309           Never enable this option on a distribution kernel.
 310
 311           Say N here, unless you are building a kernel for your own

 323           display state, video output devices in use, whether there is a X
 324           server running, phase of the moon, and the current mood of
 325           Schroedinger's cat.  If you can use X.org's RandR to control
 326           your ThinkPad's video output ports instead of this feature,
 327           don't think twice: do it and say N here to save memory and avoid
 328           bad interactions with X.org.
 329
 330           NOTE: access to this feature is limited to processes with the
 331           CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
 332           where it interacts badly with X.org.

 342           Some thinkpad models benefit from NVRAM polling to detect a few of
 343           the hot key press events.  If you know your ThinkPad model does not
 344           need to do NVRAM polling to support any of the hot keys you use,
 345           unselecting this option will save about 1kB of memory.
 346
 347           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 348           unlikely to need NVRAM polling in their latest BIOS versions.
 349
 350           NVRAM polling can detect at most the following keys: ThinkPad/Access
 351           IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
 352           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

 404           This driver adds support for the ACPI-WMI (Windows Management
 405           Instrumentation) mapper device (PNP0C14) found on some systems.
 406
 407           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 408           ACPI firmware to userspace - this is done through various vendor
 409           defined methods and data blocks in a PNP0C14 device, which are then
 410           made available for userspace to call.
 411
 412           The implementation of this in Linux currently only exposes this to
 413           other kernel space drivers.
 414
 415           This driver is a required dependency to build the firmware specific
 416           drivers needed on many machines, including Acer and HP laptops.
 417
 418           It is safe to enable this driver even if your DSDT doesn't define
 419           any ACPI-WMI devices.

 437         ---help---
 438           This driver provides support for extra features of ACPI-compatible
 439           ASUS laptops. As some of Medion laptops are made by ASUS, it may also
 440           support some Medion laptops (such as 9675 for example).  It makes all
 441           the extra buttons generate standard ACPI events that go through
 442           /proc/acpi/events, and (on some models) adds support for changing the
 443           display brightness and output, switching the LCD backlight on and off,
 444           and most importantly, allows you to blink those fancy LEDs intended
 445           for reporting mail and wireless status.
 446
 447           Note: display switching code is currently considered EXPERIMENTAL,
 448           toying with these values may even lock your machine.
 449
 450           All settings are changed via /proc/acpi/asus directory entries. Owner
 451           and group for these entries can be set with asus_uid and asus_gid
 452           parameters.
 453
 454           More information and a userspace daemon for handling the extra buttons

 456
 457           If you have an ACPI-compatible ASUS laptop, say Y or M here. This
 458           driver is still under development, so if your laptop is unsupported or
 459           something works not quite as expected, please use the mailing list
 460           available on the above page (acpi4asus-user@lists.sourceforge.net).
 461
 462           NOTE: This driver is deprecated and will probably be removed soon,
 463           use asus-laptop instead.

 482           This driver adds support for access to certain system settings
 483           on "legacy free" Toshiba laptops.  These laptops can be recognized by
 484           their lack of a BIOS setup menu and APM support.
 485
 486           On these machines, all system configuration is handled through the
 487           ACPI.  This driver is required for access to controls not covered
 488           by the general ACPI drivers, such as LCD brightness, video output,
 489           etc.
 490
 491           This driver differs from the non-ACPI Toshiba laptop driver (located
 492           under "Processor type and features") in several aspects.
 493           Configuration is accessed by reading and writing text files in the
 494           /proc tree instead of by program interface to /dev.  Furthermore, no
 495           power management functions are exposed, as those are handled by the
 496           general ACPI drivers.

 512           This driver handles RFKill events for the TOS6205 Bluetooth,
 513           and re-enables it when the switch is set back to the 'on'
 514           position.
