448
449 LED control on the ThinkPad is write-only (with very few

451 impossible to know beforehand if important information will
452 be lost when one changes LED state.

621 This driver adds support for the ACPI-WMI (Windows Management
622 Instrumentation) mapper device (PNP0C14) found on some systems.
623
624 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
625 ACPI firmware to userspace - this is done through various vendor
626 defined methods and data blocks in a PNP0C14 device, which are then
627 made available for userspace to call.
628
629 The implementation of this in Linux currently only exposes this to
630 other kernel space drivers.
631
632 This driver is a required dependency to build the firmware specific
633 drivers needed on many machines, including Acer and HP laptops.
634
635 It is safe to enable this driver even if your DSDT doesn't define

565
566 LED control on the ThinkPad is write-only (with very few
567 exceptions on very ancient models), which makes it
568 impossible to know beforehand if important information will
569 be lost when one changes LED state.
570

610 need to do NVRAM polling to support any of the hot keys you use,
611 unselecting this option will save about 1kB of memory.
612
613 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
614 unlikely to need NVRAM polling in their latest BIOS versions.

840 This driver adds support for access to certain system settings
841 on "legacy free" Toshiba laptops. These laptops can be recognized by
842 their lack of a BIOS setup menu and APM support.
843
844 On these machines, all system configuration is handled through the
845 ACPI. This driver is required for access to controls not covered
846 by the general ACPI drivers, such as LCD brightness, video output,
847 etc.
848
849 This driver differs from the non-ACPI Toshiba laptop driver (located
850 under "Processor type and features") in several aspects.
851 Configuration is accessed by reading and writing text files in the
852 /proc tree instead of by program interface to /dev. Furthermore, no
853 power management functions are exposed, as those are handled by the
854 general ACPI drivers.
