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).
- Initialized with IA32_THERM_INTERRUPT. When the CPU
- temperature reaches this temperature, an interrupt is
- generated and tempX_max_alarm is set.
-tempX_max_hyst - If the CPU temperature falls below than temperature,
- an interrupt is generated and tempX_max_alarm is reset.
-tempX_max_alarm - Set if the temperature reaches or exceeds tempX_max.
- Reset if the temperature drops to or below tempX_max_hyst.
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.
number. For Package temp, this will be "Physical id Y",
where Y is the package number.
-The TjMax temperature is set to 85 degrees C if undocumented model specific
-register (UMSR) 0xee has bit 30 set. If not the TjMax is 100 degrees C as
-(sometimes) documented in processor datasheet.
+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).
