    Phoronix: Mesa 12.0.3 Is An Emergency Release For Intel Users

    Emil Velikov announced the "emergency release" this morning of Mesa 12.0.3 as the latest stable installment for the Mesa 12.0 series...

    They really should update and complete their regession tests https://people.freedesktop.org/~nh/piglit/
    And this page mentions most tests are done only with
    • R300ND: Radeon 9700 Pro; 128MB VRAM
    • R420JI: Radeon X800 Pro by ASUS; 256MB VRAM
    • R500: Radeon X1650 Pro; 512MB VRAM

    as tested gpus - this canĀ“t be for real. Is there a site about mesa regession testing that is more up to date?

    Also this https://people.freedesktop.org/~nh/p...all/index.html
    it lists only amdgpus and only up to rs690
    where are intel nvidia and radeonSI gpus piglit-status?
    cheers, t

      He, he, when piglit release some version other then v1 8 years ago, maybe we can expect something meangful for users like that too

        Piglit hasn't seen a release in a very long time because it is used as a continuously improved suite of tests for a collection of graphics cards and go implementations. It's main audience is driver developers who want the latest git code anyway, and so no one has bothered to do regular releases.

        I can assure you that it is still actively maintained and that it works with many/all of the latest and greatest cards.

        I currently use piglit for both bisecting OpenGL regressions and for developing the OpenCL runtime on my Radeon 7850 (in my spare time), and I run it on my work laptop (haswell) occasionally for other reasons.

        ā€‹ā€‹ā€‹If the bug that caused these regressions didn't have a piglit test before, you can bet there probably will be one soon.

          sounds good at first but also a bit random.
          is there a test farm somewhere with all the GPUs from the last decade at intel and AMD with different distros and cpus etc.?
          You write "many/all of the latest and greatest cards". That does not fortify my trust.
          If only the cards get tested that the devs have in their workstations, then it is no wonder mesa is regressing so often....

            Regressions - typical Linux bad code excuse.. Few hours ago i upgrade my Intel Android x86 to 6 R1 with Mesa 12.0.2 and its worse than before..

              Intel have a CI server farm for their supported hardware that runs regression tests, pretty sure that includes piglit.
              Refer the talk by Mark Janes from Intel at XDC 2015.

              I recall there being some discussion of providing limited access to this for known, established external Mesa driver developers.

              Eric Anholt recently addressed the bit rot in running Mesa's smaller set of in-tree regression tests via Travis-CI, say for developers who have a forked repository on GitHub.

                maybe this is why mesa launch this for intel

                  Intel has their own system, but it's private and not accessible to you and me. I don't know if AMD has something similar or not - i think not, though.

                    Its in Android x86 package which are all devices and i have intel graphics.
