| |
| This driver was formerly known as ibm-acpi. |

| Enables monitoring of the built-in console audio output control |

| Optionally, the driver will also allow software control (the |
| ALSA mixer will be made read-write). Please refer to the driver |
| documentation for details. |

| your ThinkPad's video output ports instead of this feature, |
| don't think twice: do it and say N here to save memory and avoid |
| bad interactions with X.org. |
| |
| NOTE: access to this feature is limited to processes with the |

| ---help--- |
| Some thinkpad models benefit from NVRAM polling to detect a few of |
| the hot key press events. If you know your ThinkPad model does not |
| need to do NVRAM polling to support any of the hot keys you use, |
| unselecting this option will save about 1kB of memory. |
| |
| ThinkPads T40 and newer, R52 and newer, and X31 and newer are |
| unlikely to need NVRAM polling in their latest BIOS versions. |
| |
| NVRAM polling can detect at most the following keys: ThinkPad/Access |
| IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute, |
| Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12). |

| This driver adds support for the ACPI-WMI (Windows Management |

| |
| ACPI-WMI is a proprietary extension to ACPI to expose parts of the |
| ACPI firmware to userspace - this is done through various vendor |
| defined methods and data blocks in a PNP0C14 device, which are then |
| made available for userspace to call. |
| |
| The implementation of this in Linux currently only exposes this to |
| other kernel space drivers. |
| |
| This driver is a required dependency to build the firmware specific |

| support some Medion laptops (such as 9675 for example). It makes all |
| the extra buttons generate standard ACPI events that go through |
| /proc/acpi/events, and (on some models) adds support for changing the |
| display brightness and output, switching the LCD backlight on and off, |
| and most importantly, allows you to blink those fancy LEDs intended |
| for reporting mail and wireless status. |
| |
| Note: display switching code is currently considered EXPERIMENTAL, |
| toying with these values may even lock your machine. |
