+Description
+-----------
+
+This driver permits reading of the internal temperature sensor of AMD
+Family 10h and 11h processors.
+
+All these processors have a sensor, but on older revisions of Family 10h
+processors, the sensor may return inconsistent values (erratum 319). The
+driver will refuse to load on these revisions unless you specify the
+"force=1" module parameter.
+
+There is one temperature measurement value, available as temp1_input in
+sysfs. It is measured in degrees Celsius with a resolution of 1/8th degree.
+Please note that it is defined as a relative value; to quote the AMD manual:
+
+  Tctl is the processor temperature control value, used by the platform to
+  control cooling systems. Tctl is a non-physical temperature on an
+  arbitrary scale measured in degrees. It does _not_ represent an actual
+  physical temperature like die or case temperature. Instead, it specifies
+  the processor temperature relative to the point at which the system must
+  supply the maximum cooling for the processor's specified maximum case
+  temperature and maximum thermal power dissipation.
+
+The maximum value for Tctl is available in the file temp1_max.
+
+If the BIOS has enabled hardware temperature control, the threshold at
+which the processor will throttle itself to avoid damage is available in
+temp1_crit and temp1_crit_hyst.
