    Default Benchmarks Of AMD's Newest Gallium3D Driver

    Phoronix: Benchmarks Of AMD's Newest Gallium3D Driver

    While we have already published two exciting articles today looking at the native ZFS file-system for Linux and also new benchmarks of OpenSolaris / BSD / Linux, here's a third article for the day. We might as well test our new Phoronix serving infrastructure while already having excess load today due to Slashdot, etc (it's good practice for OpenBenchmarking.org), so here are benchmarks of AMD's newest Gallium3D driver compared to their classic open-source Mesa driver and also their proprietary Catalyst driver. Oh yeah, a fourth article is also in the queue for today or the very near future when AMD has a major Linux driver announcement to share.

    Default how to try

    Is there currently any noob-friendly way to try it out on Ubuntu 10.10 so that compiz also works? As in all pre-made packages and such.

    what is the "bottleneck" that keeps the gallium drivers from performing at the same -or similar- level as the proprietary ones???


    is it something in the state trackers or something in the lower parts ??

    Its about 100 developers working full time.

    i expected that to be honest


    thanks for the answer and the codes mr Airlie


    but...
    isn't there any ways to attract more developers in that area ie. an fsf/linux foundation campaign, or try to raise more money (for paying devs) from the industry, or propose some Thesis on Universities on the subject or whatever

    A slightly more useful answer might include what the specific bottlenecks are that you'd put the first 5 of those 100 developers on. Pretend I was a GPU driver development rockstar, I was hired by AMD full-time, you were my boss, and you could tell me to work on anything you wanted in any particular order: what would you want me to do first?

    Maybe you should read Jerome's letter and the rest in that thread?

    Indeed, that's a good read, and excellent work on the part of jglisse. Thanks.

    The first task would be to find the bottlenecks. With a graphics driver that is usually a pretty significant task on its own. The graphics driver and the GPU are largely decoupled by a large command buffer and periodic synchronization events so your normal "run the app and see where the time goes" approach doesn't work so well.

    It's more like "run the app, see where the time goes, develop a theory, talk to a few people, if they don't totally demolish your theory then write a bunch of code, see if it makes that app go faster, be happy because it does, test your change on other apps, get PO'ed because your change makes the other apps run slower, repeat".

    Finding bottlenecks would be a good job for the first 5 developers.
