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).
