Documentation/hwmon/k10temp says: | There is one temperature measurement value, available as temp1_input in | sysfs. It is measured in degrees Celsius with a resolution of 1/8th degre= e. | Please note that it is defined as a relative value; to quote the AMD manu= al: | | Tctl is the processor temperature control value, used by the platform to | control cooling systems.
