 229           This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
 230           support for Fn-Fx key combinations, Bluetooth control, video

 232           For more information about this driver see

 234           <http://ibm-acpi.sf.net/> .
 235
 236           This driver was formerly known as ibm-acpi.
 237
 238           Extra functionality will be available if the rfkill (CONFIG_RFKILL)
 239           and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
 240           Note that if you want ThinkPad-ACPI to be built-in instead of
 241           modular, ALSA and rfkill will also have to be built-in.

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

 294           Overriding LED state on ThinkPads can mask important

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

 326           don't think twice: do it and say N here to save memory and avoid
 327           bad interactions with X.org.
 328
 329           NOTE: access to this feature is limited to processes with the
 330           CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
 331           where it interacts badly with X.org.

 343           need to do NVRAM polling to support any of the hot keys you use,

 345
 346           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 347           unlikely to need NVRAM polling in their latest BIOS versions.
 348
 349           NVRAM polling can detect at most the following keys: ThinkPad/Access
 350           IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
 351           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

 394
 395           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 396           ACPI firmware to userspace - this is done through various vendor
 397           defined methods and data blocks in a PNP0C14 device, which are then
 398           made available for userspace to call.
 399
 400           The implementation of this in Linux currently only exposes this to
 401           other kernel space drivers.

 404           drivers needed on many machines, including Acer and HP laptops.
 405
 406           It is safe to enable this driver even if your DSDT doesn't define
 407           any ACPI-WMI devices.
 408
 409 config MSI_WMI
 410         tristate "MSI WMI extras"
 411         depends on ACPI_WMI
 412         depends on INPUT
 413         depends on BACKLIGHT_CLASS_DEVICE
 414         select INPUT_SPARSEKMAP
 415         help
 416          Say Y here if you want to support WMI-based hotkeys on MSI laptops.
 417
 418          To compile this driver as a module, choose M here: the module will
 419          be called msi-wmi.
 420
 421 config ACPI_ASUS
 422         tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
 423         depends on ACPI
 424         select BACKLIGHT_CLASS_DEVICE
 425         ---help---
 426           This driver provides support for extra features of ACPI-compatible
 427           ASUS laptops. As some of Medion laptops are made by ASUS, it may also
 428           support some Medion laptops (such as 9675 for example).  It makes all
 429           the extra buttons generate standard ACPI events that go through
 430           /proc/acpi/events, and (on some models) adds support for changing the
 431           display brightness and output, switching the LCD backlight on and off,
 432           and most importantly, allows you to blink those fancy LEDs intended
 433           for reporting mail and wireless status.
 434
 435           Note: display switching code is currently considered EXPERIMENTAL,
 436           toying with these values may even lock your machine.
 437
 438           All settings are changed via /proc/acpi/asus directory entries. Owner
 439           and group for these entries can be set with asus_uid and asus_gid
 440           parameters.
 441
 442           More information and a userspace daemon for handling the extra buttons
 443           at <http://acpi4asus.sf.net>.
 444
 445           If you have an ACPI-compatible ASUS laptop, say Y or M here. This
 446           driver is still under development, so if your laptop is unsupported or
 447           something works not quite as expected, please use the mailing list
 448           available on the above page (acpi4asus-user@lists.sourceforge.net).
 449
 450           NOTE: This driver is deprecated and will probably be removed soon,
 451           use asus-laptop instead.
 452
 453 config TOPSTAR_LAPTOP
 454         tristate "Topstar Laptop Extras"
 455         depends on ACPI
 456         depends on INPUT
 457         ---help---
 458           This driver adds support for hotkeys found on Topstar laptops.
 459
 460           If you have a Topstar laptop, say Y or M here.
 461
 462 config ACPI_TOSHIBA
 463         tristate "Toshiba Laptop Extras"
 464         depends on ACPI
 465         depends on INPUT

 467         select INPUT_POLLDEV
 468         select BACKLIGHT_CLASS_DEVICE
 469         ---help---
 470           This driver adds support for access to certain system settings
 471           on "legacy free" Toshiba laptops.  These laptops can be recognized by
 472           their lack of a BIOS setup menu and APM support.
 473
 474           On these machines, all system configuration is handled through the
 475           ACPI.  This driver is required for access to controls not covered
 476           by the general ACPI drivers, such as LCD brightness, video output,
 477           etc.
 478
 479           This driver differs from the non-ACPI Toshiba laptop driver (located
 480           under "Processor type and features") in several aspects.
 481           Configuration is accessed by reading and writing text files in the
 482           /proc tree instead of by program interface to /dev.  Furthermore, no
 483           power management functions are exposed, as those are handled by the
 484           general ACPI drivers.
 485
 486           More information about this driver is available at
 487           <http://memebeam.org/toys/ToshibaAcpiDriver>.
 488
 489           If you have a legacy free Toshiba laptop (such as the Libretto L1
 490           series), say Y.

 492 config TOSHIBA_BT_RFKILL
 493         tristate "Toshiba Bluetooth RFKill switch support"
 494         depends on ACPI
 495         ---help---
 496           This driver adds support for Bluetooth events for the RFKill
 497           switch on modern Toshiba laptops with full ACPI support and
 498           an RFKill switch.
 499
 500           This driver handles RFKill events for the TOS6205 Bluetooth,
 501           and re-enables it when the switch is set back to the 'on'
 502           position.
 503
 504           If you have a modern Toshiba laptop with a Bluetooth and an
 505           RFKill switch (such as the Portege R500), say Y.
