351 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.

352 Note that if you want ThinkPad-ACPI to be built-in instead of

368 If this option is enabled, ThinkPad-ACPI will export an ALSA card

369 with a single read-only mixer control, which should be used for

370 on-screen-display feedback purposes by the Desktop Environment.

371

372 Optionally, the driver will also allow software control (the

373 ALSA mixer will be made read-write). Please refer to the driver

374 documentation for details.

375

406 Overriding LED state on ThinkPads can mask important

407 firmware alerts (like critical battery condition), or misled

408 the user into damaging the hardware (undocking or ejecting

409 the bay while buses are still active), etc.

410

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

412 exceptions on very ancient models), which makes it

413 impossible to know beforehand if important information will

414 be lost when one changes LED state.

415

416 Users that know what they are doing can enable this option

417 and the driver will allow control of every LED, including

418 the ones on the dock stations.

419

420 Never enable this option on a distribution kernel.

435 server running, phase of the moon, and the current mood of

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

439 bad interactions with X.org.

440

441 NOTE: access to this feature is limited to processes with the

442 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms

443 where it interacts badly with X.org.

453 Some thinkpad models benefit from NVRAM polling to detect a few of

454 the hot key press events. If you know your ThinkPad model does not

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

456 unselecting this option will save about 1kB of memory.

457

458 ThinkPads T40 and newer, R52 and newer, and X31 and newer are

459 unlikely to need NVRAM polling in their latest BIOS versions.

460

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

620 This driver adds support for access to certain system settings

621 on "legacy free" Toshiba laptops. These laptops can be recognized by

622 their lack of a BIOS setup menu and APM support.

623

624 On these machines, all system configuration is handled through the

625 ACPI. This driver is required for access to controls not covered

626 by the general ACPI drivers, such as LCD brightness, video output,

627 etc.

628

629 This driver differs from the non-ACPI Toshiba laptop driver (located

630 under "Processor type and features") in several aspects.

631 Configuration is accessed by reading and writing text files in the

632 /proc tree instead of by program interface to /dev. Furthermore, no

633 power management functions are exposed, as those are handled by the

634 general ACPI drivers.

635

636 More information about this driver is available at

637 <http://memebeam.org/toys/ToshibaAcpiDriver>.

639 If you have a legacy free Toshiba laptop (such as the Libretto L1

640 series), say Y.

647 switch on modern Toshiba laptops with full ACPI support and

648 an RFKill switch.

649

650 This driver handles RFKill events for the TOS6205 Bluetooth,

651 and re-enables it when the switch is set back to the 'on'

652 position.

666 detects a sudden move or a harsh vibration, as well as an

667 ACPI notify event 0x81 whenever the movement or vibration has

668 been stabilized.

669

670 Also provides sysfs entries to get/set the desired protection

671 level and reseting the HDD protection interface.

743 This option provides a means to manipulate Isolated Memory Regions.

744 IMRs are a set of registers that define read and write access masks

745 to prohibit certain system agents from accessing memory with 1 KiB

746 granularity.

747

748 IMRs make it possible to control read/write access to an address

749 by hardware agents inside the SoC. Read and write masks can be

750 defined for:

751 - eSRAM flush

752 - Dirty CPU snoop (write only)

753 - RMU access

754 - PCI Virtual Channel 0/Virtual Channel 1

755 - SMM mode

756 - Non SMM mode

759 registers during its bootup process.

771 feature without proper support may void your hardware warranty.

772

773 If the proper BIOS support is found the driver will load and create

774 /sys/devices/system/ibm_rtl/. The "state" variable will indicate

775 whether or not the BIOS is in PRTM.

872 then reboots into Linux, the system may remain configured to resume

873 on suspend. In the absence of any userspace to support it, the system

874 will then remain awake until something triggers another suspend.
