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

+All these processors have a sensor, but on those for Socket F or AM2+,
+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.
+
+Due to technical reasons, the driver can detect only the mainboard's
+socket type, not the processor's actual capabilities. Therefore, if you
+are using an AM3 processor on an AM2+ mainboard, you can safely use the
+"force=1" 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.
