Overview
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.
