•
Max Thread ID
: The maximum Thread ID data provides the number of supported
processor threads. Note that this value is dependent on the number of cores within
the processor as determined by the processor SKU and is independent of whether
certain cores or corresponding threads are enabled or disabled.
•
CPU Microcode Update Revision
: Reflects the revision number for the microcode
update and power control unit firmware updates on the processor sample. The
revision data is a unique 32-bit identifier that reflects a combination of specific
versions of the processor microcode and PCU control firmware.
•
Machine Check Status
: Returns error information as logged by the processor
power control unit.

Package Power SKU Unit Read
This feature enables the PECI host to read the units of time, energy and power used in
the processor and DRAM power control registers for calculating power and timing
parameters. In
, the default value of the power unit field [19:16] is 0111b,
energy unit [11:8] is 0000b and the time unit [3:0] is 0011b. Actual unit values are
calculated as shown in
