Release Notes: This version has a new ucevent tool for monitoring uncore metrics like memory bandwidth, power management, QPI, last level caches, and others in a friendly manner on Sandy Bridge EP. The toplev cycle decomposition tool now supports more metrics and more CPUs. Event files for ocperf were updated for supported CPUs. There were various bugfixes and other enhancements.
Release Notes: This version added "toplev.py" for implementing high level cycle decomposition for Intel Ivy Bridge (and Sandy Bridge and Haswell in more limited ways). This allows you to determine which part of the CPU pipeline is a bottleneck for a workload. It also has plotting tools that plot the result, and pebs-grabber, which tracks raw PEBS data through perf. A new tool for normalizing "perf stat -Ixxx -x" output has been added.
Release Notes: This is the current release snapshot. pmu-tools is on a rolling release model.
