The X team and I would like to get a MRE for mesa stable point releases. As a first crack at this, I'm asking for a provisional MRE for mesa 8.0.3 in precise-updates.
Mesa releases micro releases from its stable branch; 8.0.3 is the third of these, there will be 8.0.4 shortly. The stable branch generally doesn't see further updates after the next major release, but some good fixes tend to be accumulated until then. Mesa is a bit of a special beast; it doesn't have in-source regression tests but it *does* have an extensive regression and conformance suite called piglit. Also, since Mesa touches hardware, running this regression suite as a part of the build on the buildds does not make sense. Instead I propose that we run piglit on the QA infrastructure - there's a wide variety of graphical hardware in there, so we can be reasonably confident that if piglit does not regress on the QA hardware then it will not regress elsewhere. (Bryce has already run piglit against 8.0.3 on all his hardware without regression) In the past we've failed to pick up any but the simplest bugfixes for mesa, both due to concerns about regressions and because all but the simplest fixes appear quite complex, making the SRU team justifiably nervous. I hope that piglit on the QA machines can sooth our concerns about regressions, and that the MRE can make it easier for the SRU team to accept.
