    Default The New R300 Register Allocator Is Still Being Developed

    Phoronix: The New R300 Register Allocator Is Still Being Developed

    Tom Stellard, the student developer who participated in last year's Google Summer of Code to improve the R300 GLSL compiler for the open-source ATI/AMD driver, is still around and contributing to upstream Mesa. Last month he announced his new R300 register allocator being ready for wider testing. He's now announced further improvements on this GPU register allocator for Mesa...

    Its nice with all the work being done, but isn't the performance of the R300 at an acceptable level now? Maybe focusing on code for newer chips would give more in the long run?

    At the moment, a lot of work is going into improving the core mesa functionality but using the r300-r500 chips. Some of the work is being done specifically for the r300 drivers, but a lot of it can carry over to benefit other drivers as well.

    I'm not familiar with the code itself, but I'm guessing no. It may be useful in optimizing register allocation in general, but it might also only work for r300.

    Good grief. Stop complaining about what other people choose to spend their free time on.

    This is one of the "quirks" of open source IMO. In a world where features & quality is all that matters you simply cannot treat parts of the infrastructure as "hobby projects". Of course you cannot force people to work on certain things so....

    And yes you can always install a blob but FOSS needs to have a feature complete graphic stack at some point.

    It will always be a hobby project as long as it's free.

    The kernel has managed to do something that the graphics people haven't. It managed to create a financially sustainable ecosystem around it that allows it to be free and open and -more important- support the people working on it. At least some of them.

    This was presumably achieved because the kernel was cheaper and better in every way compared to the competition.

    And thats the challenge to the graphics people. Can they create an ecosystem that can sustain itself and be attractive for companies or whatever to put their money on?

    Wayland is getting some attention. Intel is employing the main dev and nokia people hack on it. Also they got meego running on it but thats only part of the graphic stack. Mesa/G3D needs to find a way of becoming more attractive.

    I am not complaining about his work...
