-Description
------------
-This driver permits reading the DTS (Digital Temperature Sensor) embedded
-inside Intel CPUs. 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).
