Intel® Processor Trace
Intel® Processor Trace (Intel® PT) is a tracing capability added to Intel® Architecture, for use in software debug and profiling. Intel® PT provides the capability for more precise software control flow and timing information, with limited impact on software execution. This provides an enhanced ability to debug software crashes, hangs, or other anomalies, as well as responsiveness and short-duration performance issues.
Intel® VTune™ Amplifier for Systems and the Intel® System Debugger are part of Intel® System Studio 2015 (and newer) product, which includes updates for the new debug and trace features, including Intel® PT and Intel® Trace Hub.
Intel® System Studio 2015 is available for download at https://software.intel.com/en-us/system-studio.
An update to the Linux* performance utility, with support for Intel® PT, is available for download at https://github.com/virtuoso/linux-perf/tree/intel_pt. It requires rebuilding the kernel and the perf utility.
