This driver can read both the per-core and per-package -temperature using the appropriate sensors. The per-package sensor is new; -as of now, it is present only in the SandyBridge platform. The driver will -show the temperature of all cores inside a package under a single device -directory inside hwmon. - -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 processor, -which depends on the CPU model. See table below. 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: - -All Sysfs entries are named with their core_id (represented here by 'X'). -tempX_input - Core temperature (in millidegrees Celsius). -tempX_max - All cooling devices should be turned on (on Core2). -tempX_crit - Maximum junction temperature (in millidegrees Celsius). -tempX_crit_alarm - Set when Out-of-spec bit is set, never clears. - Correct CPU operation is no longer guaranteed. -tempX_label - Contains string "Core X", where X is processor - number. For Package temp, this will be "Physical id Y", - where Y is the package number. - -On CPU models which support it, TjMax is read from a model-specific register. -On other models, it is set to an arbitrary value based on weak heuristics. -If these heuristics don't work for you, you can pass the correct TjMax value -as a module parameter (tjmax). - -Appendix A.
