    Phoronix: R600/700 Mesa Driver Picks Up Blit Support

    While a blitter module was introduced for Gallium3D that uses the 3D engine for blitting, this doesn't help those without blit support that are still running the "classic" Mesa driver stack. Over the night, however, blit support has arrived for the ATI R600/700 Mesa driver...

    Almost certainly not. Lucid is a long term support release, and I cannot imagine them updating to mesa 7.8 a bare month before release.

    Ok, that was just my assumption cause it worked before updating.

    Hm...after updating the kernel, libdrm, mesa and xf86-video-ati to the current git release vsync (that comes with irq support) doesn't work anymore. Is that related to blit support?

    I didn't found an error in dmesg and xorg.0.log.

    I'm using kernel 2.6.33rc4 on both, libdrm, mesa and xf86-video-ati from git but still 1.6.2 X server on both.
    Would upgrading to a more recent Xserver would make a difference?
    As I said before, this code will not affect gears performance. It will only improve performance for applications that use glCopyTexImage or glCopyTexSubImage. glxgears does not use textures at all.

    glxgears didn't change at all for me either with this patch. But QuakeLive did.

    Well, obviously, nobody's really interested in speeding up glxgears in itself, but since most people here seemed to get much higher fps, I figured I could test that, since I don't play games and thus don't plan to test QuakeLive.
    Well, never mind. I was merelly curious, I'm not that concerned.
