The first development release of Phoronix Test Suite 3.8-Bygland is now available for testing.

Phoronix Test Suite 3.8 will be the last release in the PTS3 series when it's released later this quarter, which will then be succeeded later this year by Phoronix Test Suite 4.0. Within Phoronix Test Suite 3.8 will be more significant improvements to our open-source benchmarking / automated testing framework, some of which have landed in this "milestone 1" release.

The most significant user-facing work in Phoronix Test Suite 3.8 Milestone 1 is the large internal re-work to pts_Graph, which handles generating all of the graphs and tables for displaying Phoronix Test Suite results. Read more interactive graphs for benchmarks to learn about the changes to pts_Graph that affect how these visuals are created. The improvements will allow for creating more interactive SVG graphs, faster rendering of graphs, and other special enhancements to the visuals on With Bygland Milestone 1, the pts_Graph should be generating graphs properly and similar to version 3.6, but some further work will still be landing this development cycle.

With Phoronix Test Suite 3.8 Milestone 1 are also hardware / software detection improvements for ARM-based systems. Thanks to testing and verification work from the PandaBoard ES and CompuLab Trim-Slice, there's a variety of improvements to enhance the embedded ARM benchmarking.

The MATISK testing module in Bygland has also received a number of improvements. Read How-To: Find The Mesa Performance Regressions for details about this latest auto testing work.

Beyond these changes, there's also some internal code clean-ups, other minor enhancements, and prep work for further Bygland changes and early Phoronix Test Suite 4.0 preparations. Listed below is the official change-log.
