Description
Data (dword)
Read status of
N/A "Wake on PECI"
mode bit
Returns the total run
N/A
time.
Returns the
maximum processor
N/A
die temperature in
PECI format.
Read the maximum
DTS temperature of
a particular core or
N/A the System Agent
within the processor
die in relative PECI
temperature format
Returns the
maximum processor
N/A junction
temperature and
processor T
CONTROL
Read the thermal
status register and
optionally clear any
log bits. The register
includes status and
N/A
log bits for TCC
activation,
PROCHOT_N
assertion and Critical
Temperature.

Averaging Constant
Constant
Read the time for
which the processor
has been operating
N/A
in a lowered power
state due to internal
TCC activation.
Reads the current
N/A limit on the VCC
power plane
Returns the value of
the energy
consumed by just
N/A
the VCC power plane
or entire CPU
package.
