    Phoronix: The Grinch That Stole The Radeon Gallium3D Performance?

    There are some significant performance drops right now on Mesa master for the forthcoming 7.12/8.0 release concerning the Gallium3D driver for older ATI Radeon graphics processors. The performance of the R300g driver is now setback compared to earlier Mesa releases.

    The regressed commits should be published on Christmas.

    Also, please compare the visual output. Maybe about three screenshots over the duration of the test.
    Just to show whether it's just a performance regression or whether it actually renders more and better.

    Don't you actually mean this is an R300g issue, which does not include support for any RadeonHD models?

    I notice you didn't check out r600g, which does support all the RadeonHD models.

    Also worth a mention but not really a big issue is r100 and r200, but those cards are so old that I doubt anyone using them is running anything too stressful on the GPU.

    Phoronix, where they post better articles than just reprints of ads.

    Bug reports that generate revenue maintain the tester's income and interest, as well as awareness in the community. In the graphics community a lot of the developers read Phoronix so the message isn't being lost (as evidence, it looks like they already found this regression).

    Kudos Michael.
