259 | ||
260 | If this option is enabled, ThinkPad-ACPI will export an ALSA card | |

298 | Overriding LED state on ThinkPads can mask important | |

300 | the user into damaging the hardware (undocking or ejecting | |
301 | the bay while buses are still active), etc. | |
302 | ||
303 | LED control on the ThinkPad is write-only (with very few | |
304 | exceptions on very ancient models), which makes it | |
305 | impossible to know beforehand if important information will | |

346 | the hot key press events. If you know your ThinkPad model does not | |
347 | need to do NVRAM polling to support any of the hot keys you use, | |
348 | unselecting this option will save about 1kB of memory. | |
349 | ||
350 | ThinkPads T40 and newer, R52 and newer, and X31 and newer are | |

462 | driver is still under development, so if your laptop is unsupported or | |
463 | something works not quite as expected, please use the mailing list | |
464 | available on the above page (acpi4asus-user@lists.sourceforge.net). | |

486 | This driver adds support for access to certain system settings | |
487 | on "legacy free" Toshiba laptops. These laptops can be recognized by | |
488 | their lack of a BIOS setup menu and APM support. | |
489 | ||
490 | On these machines, all system configuration is handled through the | |
491 | ACPI. This driver is required for access to controls not covered | |
492 | by the general ACPI drivers, such as LCD brightness, video output, | |
493 | etc. | |
494 | ||
495 | This driver differs from the non-ACPI Toshiba laptop driver (located | |
496 | under "Processor type and features") in several aspects. | |
497 | Configuration is accessed by reading and writing text files in the | |
498 | /proc tree instead of by program interface to /dev. Furthermore, no | |
499 | power management functions are exposed, as those are handled by the | |
500 | general ACPI drivers. | |
501 | ||
502 | More information about this driver is available at | |

513 | switch on modern Toshiba laptops with full ACPI support and | |
514 | an RFKill switch. | |
515 | ||
516 | This driver handles RFKill events for the TOS6205 Bluetooth, | |
517 | and re-enables it when the switch is set back to the 'on' | |
518 | position. | |
519 | ||
520 | If you have a modern Toshiba laptop with a Bluetooth and an | |
521 | RFKill switch (such as the Portege R500), say Y. | |

555 | ---help--- | |
556 | This driver allows other kernel drivers access to the | |
557 | contents of the restricted access region control registers. | |
558 | ||
559 | The restricted access region control registers | |
560 | (rar_registers) are used to pass address and | |
561 | locking information on restricted access regions | |
562 | to other drivers that use restricted access regions. | |
563 | ||
564 | The restricted access regions are regions of memory | |
565 | on the Intel MID Platform that are not accessible to | |
566 | the x86 processor, but are accessible to dedicated | |
567 | processors on board peripheral devices. | |
568 | ||
569 | The purpose of the restricted access regions is to | |
570 | protect sensitive data from compromise by unauthorized | |
571 | programs running on the x86 processor. | |
