+This driver permits reading temperature sensor embedded inside Intel Core CPU. +Temperature is measured in degrees Celsius and measurement resolution is +1 degree C. Valid temperatures are from 0 to TjMax degrees C, because +the actual temperature is in fact a delta from TjMax. + +Temperature known as TjMax is the maximum junction temperature of processor. +Intel defines this temperature as 85C or 100C. At this temperature, protection +mechanism will perform actions to forcibly cool down the processor. Alarm +may be raised, if the temperature grows enough (more than TjMax) to trigger +the Out-Of-Spec bit. Following table summarizes the exported sysfs files: + +temp1_input - Core temperature (in milidegrees of Celsius). +temp1_crit - Maximum junction temperature (in milidegrees of Celsius). +temp1_crit_alarm - Set when Out-of-spec bit is set, never clears. + Correct CPU operation is no longer guaranteed. +temp1_label - Contains string with the "Core X", where X is processor + number. + +The TjMax temperature is set to 85C if undocumented model specific register +(UMSR) 0xee has bit 30 set. If not the TjMax is 100C as documented in processor +datasheet. Intel will not disclose this information to individuals. How to get it working:
