    Default Radeon VRAM Optimizations Coming, But Help Is Needed

    Phoronix: Radeon VRAM Optimizations Coming, But Help Is Needed

    Got a workload that runs badly on the r600g Radeon Gallium3D driver? You can help fix it! Optimizations are coming to the open-source Radeon Linux driver for video memory usage...

    I have a r600 and am willing to put a bit off effort in to helping, but i wonder if the problem is that vram detection in steam and xorg.

    Steam reports 1GB under windows, xorg reports a weird number around 800MB, steam says it desnt detect any VRAM.

    I've got a 6850 (pci express), 3200 (IGP), a 5400 (PCI), and a 7850... One of the machines I've got laying around is somewhat idle and can be reformatted at will.

    Anyone have any game suggestions?

    I guess I could start with Serious Sam 3, TF2, Oil Rush, and go from there.

    Expeditions: Conquistador? I'd do it myself, but I relegated the r600 card I have to my HTPC, so it's not equipped to run any games at the moment...

    ...I fail to see how this really matters to the topic at hand or at all, but: http://en.wikipedia.org/wiki/Lauri
    Lauri is an Estonian and Finnish male given name.

    That's unrelated to this; please open a bug and attach an apitrace.

    Yes, all r600g cards, integrated or not. Doesn't matter if they have dedicated VRAM or if they use system RAM, as that info is not recorded.

    I believe you need to start the game manually. Here's an example for Metro LL: https://bugs.freedesktop.org/show_bug.cgi?id=71239#c16

    OpenGL ES also counts? LLVM vs no-LLVM backend matter?
    Any API counts, including OpenVG or even the DX9 state tracker. LLVM or no LLVM doesn't matter.

    They wouldn't be useful in the current state. I don't have a SI card, so I can't do the SI side code (can't test). Would you like to help finish the SI side, so SI owners can record too?

    Others:
    Thanks to Pontostroy and pre-emptively to Veerappan and Adarion.

    Actually i unfairly blamed xorg, its close

    [ 25.566] (II) RADEON(0): [DRI2] Setup complete
    [ 25.566] (II) RADEON(0): [DRI2] DRI driver: r600
    [ 25.566] (II) RADEON(0): [DRI2] VDPAU driver: r600
    [ 25.566] (II) RADEON(0): Front buffer size: 8640K
    [ 25.566] (II) RADEON(0): VRAM usage limit set to 928335K
    [ 25.566] (==) RADEON(0): Backing store disabled
    [ 25.566] (II) RADEON(0): Direct rendering enabled

    Well, those oibaf drivers crashed compiz for me (wouldnt boot).
    Install fglrx, getting min 80fps on TF2 with min settings, was down to 13fps with stock radeon driver (with some corruption).
    Try and go back to open source radeon driver and its black screen...

    Long way to go.

    PS: steam doesnt detect vram with fglrx drivers either, so i assume its just a reporting problem not a detection problem.
