    +Kernel driver peci-cputemp
    +==========================
    +
    +Supported chips:
    + One of Intel server CPUs listed below which is connected to a PECI bus.
    + * Intel Xeon E5/E7 v3 server processors

    +Description
    +-----------
    +
    +This driver implements a generic PECI hwmon feature which provides Digital
    +Thermal Sensor (DTS) thermal readings of the CPU package and CPU cores that are
    +accessible using the PECI Client Command Suite via the processor PECI client.
    +
    +All temperature values are given in millidegree Celsius and will be measurable
    +only when the target CPU is powered on.
    +
    +sysfs attributes
    +----------------
    +
    +temp1_label "Die"
    +temp1_input Provides current die temperature of the CPU package.
    +temp1_max Provides thermal control temperature of the CPU package
    + which is also known as Tcontrol.
    +temp1_crit Provides shutdown temperature of the CPU package which
    + is also known as the maximum processor junction
    + temperature, Tjmax or Tprochot.
    +temp1_crit_hyst Provides the hysteresis value from Tcontrol to Tjmax of
    + the CPU package.
    +
    +temp2_label "Tcontrol"
    +temp2_input Provides current Tcontrol temperature of the CPU
    + package which is also known as Fan Temperature target.
    + Indicates the relative value from thermal monitor trip
    + temperature at which fans should be engaged.
    +temp2_crit Provides Tcontrol critical value of the CPU package
    + which is same to Tjmax.
    +
    +temp3_label "Tthrottle"
    +temp3_input Provides current Tthrottle temperature of the CPU
    + package. Used for throttling temperature. If this value
    + is allowed and lower than Tjmax - the throttle will
    + occur and reported at lower than Tjmax.
    +
    +temp4_label "Tjmax"
    +temp4_input Provides the maximum junction temperature, Tjmax of the
    + CPU package.
    +
    +temp[5-*]_label Provides string "Core X", where X is resolved core
    + number.
    +temp[5-*]_input Provides current temperature of each core.
    +temp[5-*]_max Provides thermal control temperature of the core.
    +temp[5-*]_crit Provides shutdown temperature of the core.
    +temp[5-*]_crit_hyst Provides the hysteresis value from Tcontrol to Tjmax of
    + the core.

    +This driver implements a generic PECI hwmon feature which provides Digital
    +Thermal Sensor (DTS) thermal readings of DIMM components that are accessible
    +using the PECI Client Command Suite via the processor PECI client.
    +
    +All temperature values are given in millidegree Celsius and will be measurable
    +only when the target CPU is powered on.
    +
    +sysfs attributes
    +----------------
    +
    +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.
    +
    +Note:
    + DIMM temperature attributes will appear when the client CPU's BIOS
    + completes memory training and testing.
