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

401 your ThinkPad's video output ports instead of this feature,

403 bad interactions with X.org.
405 NOTE: access to this feature is limited to processes with the

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).

667 and re-enables it when the switch is set back to the 'on'
668 position.
670 If you have a modern Toshiba laptop with a Bluetooth and an
671 RFKill switch (such as the Portege R500), say Y.

727 depends on PCI && X86_MRST
728 default n
729 ---help---
730 This driver allows other kernel drivers access to the
731 contents of the restricted access region control registers.
733 The restricted access region control registers
734 (rar_registers) are used to pass address and
735 locking information on restricted access regions
736 to other drivers that use restricted access regions.
738 The restricted access regions are regions of memory
739 on the Intel MID Platform that are not accessible to
740 the x86 processor, but are accessible to dedicated
741 processors on board peripheral devices.
743 The purpose of the restricted access regions is to
744 protect sensitive data from compromise by unauthorized
745 programs running on the x86 processor.
747 config INTEL_IPS

750 ---help---
751 Intel Calpella platforms support dynamic power sharing between the
752 CPU and GPU, maximizing performance in a given TDP. This driver,
753 along with the CPU frequency and i915 drivers, provides that
754 functionality. If in doubt, say Y here; it will only load on
755 supported platforms.

761 Enable support for IBM Premium Real Time Mode (PRTM).
762 This module will allow you the enter and exit PRTM in the BIOS via
763 sysfs on platforms that support this feature. System in PRTM will
764 not receive CPU-generated SMIs for recoverable errors. Use of this
765 feature without proper support may void your hardware warranty.
767 If the proper BIOS support is found the driver will load and create
768 /sys/devices/system/ibm_rtl/. The "state" variable will indicate
769 whether or not the BIOS is in PRTM.
770 state = 0 (BIOS SMIs on)
771 state = 1 (BIOS SMIs off)

794 This module implements a driver for a wide range of different
795 Samsung laptops. It offers control over the different
796 function keys, wireless LED, LCD backlight level, and
797 sometimes provides a "performance_control" sysfs file to allow
798 the performance level of the laptop to be changed.
800 To compile this driver as a module, choose M here: the module
801 will be called samsung-laptop.
