17.9.1
Package Identifier Read (Index = 0)
This feature enables the PECI host to uniquely identify the PECI client processor. The
parameter field encodings shown in
typically the BMC, to access the relevant processor information as described below.
17.9.1.1
CPU ID Information
This is data field contains the equivalent information that can be accessed through
executing the Intel
®
architecture CPUID instruction. It contains the processor type,
stepping, model and family ID information as shown in
17.9.1.2
Platform ID
This is data field can be used to ensure processor microcode updates are compatible
with the processor. Note that the value of the Platform ID or Processor Flag[2:0] as
shown in
is typically unique to the platform type and processor stepping.
Refer to the processor Avoton/Rangeley SoC BIOS Writer’s Guide (BWG) for more
information.
17.9.1.3
Max Thread ID
This is data field 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. See
.
