  259. firmware alerts (like critical battery condition), or misled
  260. the user into damaging the hardware (undocking or ejecting
  261. the bay while buses are still active), etc.
  262. LED control on the ThinkPad is write-only (with very few
  263. exceptions on very ancient models), which makes it
  264. impossible to know beforehand if important information will
  265. be lost when one changes LED state.
  266. Users that know what they are doing can enable this option
  267. and the driver will allow control of every LED, including
  268. the ones on the dock stations.

  284. don't think twice: do it and say N here to save memory and avoid
  285. bad interactions with X.org.
  286. NOTE: access to this feature is limited to processes with the
  287. CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
  288. where it interacts badly with X.org.

  297. the hot key press events. If you know your ThinkPad model does not
  298. need to do NVRAM polling to support any of the hot keys you use,
  299. unselecting this option will save about 1kB of memory.
  300. ThinkPads T40 and newer, R52 and newer, and X31 and newer are
  301. unlikely to need NVRAM polling in their latest BIOS versions.
  302. NVRAM polling can detect at most the following keys: ThinkPad/Access

  304. Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

  377. It is safe to enable this driver even if your DSDT doesn't define
  378. any ACPI-WMI devices.

  394. This driver provides support for extra features of ACPI-compatible
  395. ASUS laptops. As some of Medion laptops are made by ASUS, it may also
  396. support some Medion laptops (such as 9675 for example). It makes all
  397. the extra buttons generate standard ACPI events that go through
  398. /proc/acpi/events, and (on some models) adds support for changing the
  399. display brightness and output, switching the LCD backlight on and off,
  400. and most importantly, allows you to blink those fancy LEDs intended
  401. for reporting mail and wireless status.
  402. Note: display switching code is currently considered EXPERIMENTAL,
  403. toying with these values may even lock your machine.
  404. All settings are changed via /proc/acpi/asus directory entries. Owner
  405. and group for these entries can be set with asus_uid and asus_gid
  406. parameters.
  407. More information and a userspace daemon for handling the extra buttons
  408. at <http://acpi4asus.sf.net>.
  409. If you have an ACPI-compatible ASUS laptop, say Y or M here. This
  410. driver is still under development, so if your laptop is unsupported or
  411. something works not quite as expected, please use the mailing list
  412. available on the above page (acpi4asus-user@lists.sourceforge.net).
  413. NOTE: This driver is deprecated and will probably be removed soon,
  414. use asus-laptop instead.

  434. This driver adds support for access to certain system settings
  435. on "legacy free" Toshiba laptops. These laptops can be recognized by
  436. their lack of a BIOS setup menu and APM support.
  437. On these machines, all system configuration is handled through the
  438. ACPI. This driver is required for access to controls not covered
  439. by the general ACPI drivers, such as LCD brightness, video output,
  440. etc.
  441. This driver differs from the non-ACPI Toshiba laptop driver (located
  442. under "Processor type and features") in several aspects.
  443. Configuration is accessed by reading and writing text files in the
  444. /proc tree instead of by program interface to /dev. Furthermore, no
  445. power management functions are exposed, as those are handled by the
  446. general ACPI drivers.
  447. More information about this driver is available at
  448. <http://memebeam.org/toys/ToshibaAcpiDriver>.

  457. an RFKill switch.
  458. This driver handles RFKill events for the TOS6205 Bluetooth,
  459. and re-enables it when the switch is set back to the 'on'
  460. position.

  501. This driver allows other kernel drivers access to the
  502. contents of the restricted access region control registers.
  503. The restricted access region control registers
  504. (rar_registers) are used to pass address and
  505. locking information on restricted access regions
  506. to other drivers that use restricted access regions.
  507. The restricted access regions are regions of memory
  508. on the Intel MID Platform that are not accessible to
  509. the x86 processor, but are accessible to dedicated
  510. processors on board peripheral devices.
  511. The purpose of the restricted access regions is to
  512. protect sensitive data from compromise by unauthorized
  513. programs running on the x86 processor.

  530. not receive CPU-generated SMIs for recoverable errors. Use of this
  531. feature without proper support may void your hardware warranty.
  532. If the proper BIOS support is found the driver will load and create
  533. /sys/devices/system/ibm_rtl/. The "state" variable will indicate
  534. whether or not the BIOS is in PRTM.
