18.11.5 Performance Monitoring and Intel
®
TSX
Chapter 16 of Intel® 64 and IA-32 Architectures Software Developer’s Manual, Volume 1 describes the details of
Intel® Transactional Synchronization Extensions (Intel TSX). This section describes performance monitoring
support for Intel TSX.
If a processor supports Intel TSX, the core PMU enhances it’s IA32_PERFEVTSELx MSR with two additional bit fields
for event filtering. Support for Intel TSX is indicated by either (a) CPUID.(EAX=7, ECX=0):RTM[bit 11]=1, or (b) if
CPUID.07H.EBX.HLE [bit 4] = 1. The TSX-enhanced layout of IA32_PERFEVTSELx is shown in Figure 18-40. The
two additional bit fields are:
