+Kernel driver coretemp

+Description
+-----------
+
+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 value of temperature register 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 millidegrees Celsius).
+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.
+temp1_label      - Contains string "Core X", where X is processor
+                   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.
