PECI Interface
7.1.2.7.1 Package Identifier Read
This feature enables the PECI host to uniquely identify the PECI client processor. The
parameter field encodings shown in Tab le 7 - 8 allow the PECI host to access the
relevant processor information as described below.
• CPUID data: This is the equivalent of data that can be accessed through the
CPUID instruction execution. It contains processor type, stepping, model and
family ID information as shown in Figure 7-19.
• Platform ID data: The Platform ID data identifies the platform type that the
processor is being used on as per the encodings in Ta b l e 7 - 9 . The Platform ID data
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 Figure 7-20 is typically unique to the platform type and processor stepping.
• Uncore Device ID: This information can be used to uniquely identify the processor
device when combined with the Vendor Identification register content. Refer to the
appropriate register description for the exact Intel
