43 This driver permits reading of the internal temperature sensor of AMD
44 Family 10h/11h/12h/14h/15h processors.
46 All these processors have a sensor, but on those for Socket F or AM2+,
47 the sensor may return inconsistent values (erratum 319). The driver
48 will refuse to load on these revisions unless you specify the "force=1"
51 Due to technical reasons, the driver can detect only the mainboard's
52 socket type, not the processor's actual capabilities. Therefore, if you
53 are using an AM3 processor on an AM2+ mainboard, you can safely use the
56 There is one temperature measurement value, available as temp1_input in
57 sysfs. It is measured in degrees Celsius with a resolution of 1/8th degree.
58 Please note that it is defined as a relative value; to quote the AMD manual:
60 Tctl is the processor temperature control value, used by the platform to
61 control cooling systems. Tctl is a non-physical temperature on an
62 arbitrary scale measured in degrees. It does _not_ represent an actual
63 physical temperature like die or case temperature. Instead, it specifies
64 the processor temperature relative to the point at which the system must
65 supply the maximum cooling for the processor's specified maximum case
66 temperature and maximum thermal power dissipation.
68 The maximum value for Tctl is available in the file temp1_max.
70 If the BIOS has enabled hardware temperature control, the threshold at
71 which the processor will throttle itself to avoid damage is available in
72 temp1_crit and temp1_crit_hyst.
