    Phoronix: RadeonSI GLAMOR 2D Performance vs. Catalyst

    While the RadeonSI Gallium3D driver continues making much headway as the modern open-source AMD Gallium3D Linux graphics driver along with the GLAMOR library it depends upon for 2D acceleration, the 2D performance of the Linux desktop is still quite poor compared to the proprietary Catalyst driver...

    Isn't it possible to use EXA for 2D acceleration? Very recently, kwin's compositor failed and the only way for me to get it to work was to get rid of EXA and force enable GLAMOR. My performance has taken a huge hit and some windows get visually glitchy because of it. This happened in the latest update I got (I'm using Arch).

      This is the one saving grace of having a laptop with switchable graphics (enduro): The vast bulk of the 2D work (ie, desktop) is handled by the Intel driver, so I haven't really run into much of this.

      I'd be curious to see how improved 2D rendering would effect 3D applications

        I'm pretty sure radeonsi only supports GLAMOR for 2D: http://www.phoronix.com/scan.php?pag...tem&px=MTEzNjk

            Hello, since in the end the final use of these drivers is for recreational purposes, and the increased use is through wine, you might consider doing some leaked benchmarks using wine + wine + wow and gw2? I think the only way to bring new people to linux is through the experience of the game, and these two games now holding a slice of the market, we are talking about 15/17 million users, increase efforts to improve Codest securities and also take away the 1% is not a small thing.

              interesting - totally different numbers and quite some wins over catalyst. I am running suse 13.1 too. It defaults mesa 9.3 and kernel 3.11. So Michaels git stuff regressed quite a bit in some 2d workloads...

                Bad timing. A patch that improves performance of line drawing hugely is just being reviewed on the glamor mailing list...

                  Great, but this still means it won't make it into 14.04, and even Arch won't see it until at least Spring. IE, March 2014. At the earliest. Meanwhile, the SI gpus have been shipping since January 2012.

                  I'm just worried by the time the driver works well enough for someone who wants to use Mesa, AMD won't be selling cards of this architecture anymore. It is like how, right now, if you want a good AMD card on Mesa under Linux, you need to go search ebay for a 6000 series.

                    He's using those repository (created by him!) to get the latest mesa/llvm from git, and the latest kernel rc.
