intel processor identification utility too big

It provides fine-grained information on branches taken in a program, but that means there can be a vast amount of trace data. Intel PT essentially provides control flow tracing, and you can get all the technical details in the Intel Processor Trace chapter in the Intel SDM ( ).Ĭontrol flow tracing is different from other kinds of performance analysis and debugging. Intel processors (Broadwell or newer, or Apollo Lake or newer) have a performance analysis and debugging feature called Intel® Processor Trace, or Intel® PT for short. Introduction What is Intel® Processor Trace 17 Appendix: Intel PT capabilities on different processors.

15 Example: Using PTWRITE to measure the time of an individual instruction.13 Example: Detecting System Management Mode (SMM).10 Example: Looking at Intel PT trace packets.9 Example: Using SQL to analyze latencies.5 Example: Tracing power events and CPU frequency.4 Example: Tracing short-running commands.3 Example: Tracing your own code : Hello World.2.1 Downloading and building the latest perf tools.1.1.3.2 Intel® Transactional Synchronization Extensions (Intel® TSX).1.1.2.4 Intel PT vs Branch Trace Store (BTS).1.1.2.3 Intel PT vs Last Branch Record (LBR).1.1.2.1 Intel PT vs Performance Counters.1.1.1.6 Process only a fraction of the data collected.1.1.1 Reducing and handling the massive amount of trace data.
