POWER_LIMITATION_LOG: Sticky log bit indicating that the power has transitioned
out of its limitation status since the last time SW cleared this bit. Set by HW on a 0 to
1 transition of Power Limitation Status.
10
0h
ROV
POWER_LIMITATION_STATUS: Indicates that either IA is running at P-state below
the (max P-state - offset) or that GT is running at P-state below its P1 frequency.

0h
RW0C
THRESHOLD2_LOG: Sticky log bit that asserts on a 0 to 1 or 1 to 0 transition of the
Threshold2_Status bit. HW controls this transition.
8
0h
ROV
THRESHOLD2_STATUS: Indicates that the current temperature (bits 23:16 of this
register) is equal to or higher than the Threshold2 defined in the
IA32_PACKAGE_THERM_INTERRUPT MSR. Note that because temperature and
thresholds are defined as negative offsets, a higher number means a lower
temperature.
