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 
 allow the PECI host, 
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 
.
