DESCRIPTION
     The km driver provides support for the temperature sensors available in
     the AMD Family 10h and 11h processors.

     Each chip reports one temperature sensor.  Multiprocessor systems have
     one instance of km per chip.  The highest resolution supported by the
     driver is 0.125 degC.

     Sensor values are made available through the sysctl(8) interface.
