Description |
|
----------- |
|
|
|
This driver implements a generic PECI hwmon feature which provides |
|
Temperature sensor on DIMM readings that are accessible via the processor PECI interface. |
|
|
|
All temperature values are given in millidegree Celsius and will be measurable |
|
only when the target CPU is powered on. |
|
|
|
Sysfs interface |

======================= ======================================================= |
|
|
|
temp[N]_label Provides string "DIMM CI", where C is DIMM channel and |
|
I is DIMM index of the populated DIMM. |
|
temp[N]_input Provides current temperature of the populated DIMM. |
|
temp[N]_max Provides thermal control temperature of the DIMM. |
|
temp[N]_crit Provides shutdown temperature of the DIMM. |
|

|
|
|
Note: |
|
DIMM temperature attributes will appear when the client CPU's BIOS |
|
completes memory training and testing.
