9.3.2.2 SAMPROD: Sample/Production
This location contains the sample/production field, which is a two-bit field and is LSB
aligned. All Q-spec material will use a value of 00b. All S-spec material will use a value
of 01b. All other values0 are reserved. Writes to this register have no effect.
Example: A processor with a Qxxx mark (engineering sample) will have offset 14h set
to 00h. A processor with an Sxxxx mark (production unit) will use 01h at offset 14h.
9.3.2.3 Processor Thread and Core Information
This location contains information regarding the number of cores and threads on the
processor. Writes to this register have no effect. Data format is binary.
Example: The Intel® Xeon® E7 v2 processor has up to 15 cores and two threads
per core.
