It allows recording the detailed trace of activity while the processor executes the code. One might use the recorded trace to reconstruct the code flow. It means, to find out the executed code paths, determine branches taken, and so forth. The abovementioned feature is described in Intel(R) 64 and IA-32 Architectures Software Developer's Manual Volume 3C: System Programming Guide, Part 3, Chapter 36: "Intel Processor Trace." This patch series implements an interface that Dom0 could use in order to enable IPT for particular vCPUs in DomU, allowing for external monitoring. Such a feature has numerous applications like malware monitoring, fuzzing, or performance testing.
