Intel® Xeon® Processor 7000 Series Specification Update

This document is an update to the specifications contained in the Affected Documents and Related Documents tables below. This document is a compilation of device and documentation errata, specification clarifications, and changes. It is intended for hardware system manufacturers and software developers of applications, operating systems, or tools. Information types defined in Nomenclature are consolidated into the specification update and are no longer published in other documents. This document may also contain information that was not previously published.

NOTES:

• The Extended Family corresponds to bits [27:20] of the EDX register after RESET, bits [27:20] of the EAX register after the CPUID instruction is executed with a 1 in the EAX register, and the generation field of the Device ID register accessible through Boundary Scan.
• The Extended Model corresponds to bits [19:16] of the EDX register after RESET, bits [19:16] of the EAX register after the CPUID instruction is executed with a 1 in the EAX register, and the model field of the Device ID register accessible through Boundary Scan.
• The Type corresponds to bits [13:12] of the EDX register after RESET, bits [13:12] of the EAX register after the CPUID instruction is executed with a 1 in the EAX register, and the generation field of the Device ID register accessible through Boundary Scan.
• The Family corresponds to bits [11:8] of the EDX register after RESET, bits [11:8] of the EAX register after the CPUID instruction is executed with a 1 in the EAX register, and the generation field of the Device ID register accessible through Boundary Scan.
• The Model corresponds to bits [7:4] of the EDX register after RESET, bits [7:4] of the EAX register after the CPUID instruction is executed with a 1 in the EAX register, and the model field of the Device ID register accessible through Boundary Scan. Cache and TLB descriptor parameters are provided in the EAX, EBX, ECX, and EDX registers after the CPUID instruction is executed with a 2 in the EAX register. Please refer to the AP-485 Intel® Processor Identification and the CPUID Instruction Application Note for further information on the CPUID instruction.
