BUILT IN - ARTICLE INTRO SECOND COMPONENT
Summary

Information on how Intel® Xeon® Processors support Intel® Processor Trace

Description

Unable to determine if an Intel® Xeon® Processor supports the Intel® Processor Trace feature.

Resolution

Intel® Processor Trace (Intel® PT) is an extension of Intel® Architecture and is supported starting with Intel® Xeon® Processors released in 2016 (formerly codenamed Broadwell) and later Intel® Xeon® Processors.

Notes
  • Earlier implementations of Intel® PT do not support tracing in Virtual-Machine Extensions (VMX) operation.  Starting with Intel® Xeon® Processors released in 2017 (formerly codenamed Skylake) support was added to allow Intel® PT to be used post-VXMON (instruction to enter VMX operation).
  • Hooks to virtualize Intel® PT for guest use was added starting with Intel® Xeon® Processors released in 2021 (formerly codenamed Ice Lake).

For further information, see the chapter on Intel® Processor Trace in the Intel® 64 and IA-32 Architectures Software Developer’s Manuals.
