-Description
------------
-
-This driver permits reading of the internal temperature sensor of AMD
-Family 10h/11h/12h/14h/15h processors.
-
-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.
-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.
