81H 02H UNC_THERMAL_THR
OTTLED_TEMP.CORE
_1
Cycles that the PCU records that core
1 is in the power throttled state due
to core’s temperature being above the
thermal throttling threshold.
81H 04H UNC_THERMAL_THR
OTTLED_TEMP.CORE
_2
Cycles that the PCU records that core
2 is in the power throttled state due
to core’s temperature being above the
thermal throttling threshold.
81H 08H UNC_THERMAL_THR
OTTLED_TEMP.CORE
_3
Cycles that the PCU records that core
3 is in the power throttled state due
to core’s temperature being above the
thermal throttling threshold.
