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