- 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.
