The sensors can be in core, uncore, memory controller, or -other components in a package. The feature is first implemented in Intel Sandy -Bridge platform. - -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 -value of temperature register is in fact a delta from TjMax. - -Temperature known as TjMax is the maximum junction temperature of package. -We get this from MSR_IA32_TEMPERATURE_TARGET. If the MSR is not accessible, -we define TjMax as 100 degrees Celsius. At this temperature, protection -mechanism will perform actions to forcibly cool down the package. 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 - Package temperature (in millidegrees Celsius). -temp1_max - All cooling devices should be turned on. -temp1_crit - Maximum junction temperature (in millidegrees Celsius). -temp1_crit_alarm - Set when Out-of-spec bit is set, never clears. - Correct CPU operation is no longer guaranteed. |
