thinkpad, smapi, superio, rtcmosram and thinkpadpm are device drivers for certain ThinkPad components in the form of loadable kernel modules.

The thinkpad driver merely loads the other driver modules as needed. It also provides access to the other drivers on non-devfs systems. The smapi driver is the interface to the IBM System Management Application Program Interface (SMAPI) BIOS found in some ThinkPads. The superio driver controls the Super I/O chip. The rtcmosram driver provides access to the RT/CMOS nonvolatile RAM. The thinkpadpm driver makes available certain power management functions.

Each module adds an entry under /proc/driver/thinkpad named like itself which contains some information about itself.

The thinkpad module takes the following parameters.

enable_smapi=n

Disable (0) or enable (1) use of the smapi module

enable_superio=n

Disable (0) or enable (1) use of the superio module

enable_rtcmosram=n

Disable (0) or enable (1) use of the rtcmosram module

enable_thinkpadpm=n

Disable (0) or enable (1) use of the thinkpadpm module

The user requires write permission on the device file in order to change settings or to "sedate" the machine.

/proc/driver/thinkpad

Files containing information about the drivers are in this directory.

/dev/thinkpad

This is a directory containing the following special device files:

/dev/thinkpad/thinkpad

Special device file (char, major 10, minor 170) through which ThinkPad devices are controlled

/dev/thinkpad/smapi

Special device file through which the SMAPI BIOS may be accessed

/dev/thinkpad/superio

Special device file through which the Super I/O chip may be controlled

/dev/thinkpad/rtcmosram

Special device file through which the RT CMOS RAM chip may be controlled

/dev/thinkpad/thinkpadpm

Special device file through which certain ThinkPad power management actions may be performed

None known.
