Processor Uncore Configuration Registers
4.4.3.1 Stepping Revision ID (SRID)
This register contains the revision number of the processor.
The SRID is a 4-bit hardwired value assigned by Intel, based on product’s stepping. The
SRID is not a directly addressable PCI register. The SRID value is reflected through the
RID register when appropriately addressed. The 4 bits of the SRID are reflected as the
two least significant bits of the major and minor revision field respectively. See
Table 4-1.
4.4.3.2 Compatible Revision ID (CRID)
The CRID is an 4-bit hardwired value assigned by Intel during manufacturing process.
Normally, the value assigned as the CRID will be identical to the SRID value of a
previous stepping of the product with which the new product is deemed “compatible”.
The CRID is not a directly addressable PCI register. The CRID value is reflected through
the RID register when appropriately addressed.The 4 bits of the CRID are reflected as
the two least significant bits of the major and minor revision field respectively. See
Table 4-1.
