Thread: Radeon Gallium on ubuntu

Hybrid View

    Default Radeon Gallium on ubuntu

    Hi.

    I would like to experiment with gallium for radeon. So, does anybody knows if there are available packages with gallium drivers for lucid?

    Else (sorry for the newbie questions) I guess I have to build everything from GIT. What parameters should I pass to configure scripts so that everything is Ok? Also, in order to use gallium I have to edit my xorg.conf to load radeong?

    Thank you.

    git clone git://anongit.freedesktop.org/mesa/mesa
    ./autogen.sh
    ./configure --enable-gallium-radeon --with-state-trackers=dri,glx
    cd mesa/lib/gallium/
    ln -s radeong_dri.so r300_dri.so
    export LIBGL_DRIVERS_PATH=<PATH TO>/mesa/lib/gallium/

    the applications you start from this console will use gallium now. check with glxinfo for GL2.1

    AFAIK there are no packages yet.

    So for r600 does this line change to:?
    Code:
    ln -s radeong_dri.so r600_dri.so

    I make it, but it gives
    OpenGL vendor string: Advanced Micro Devices, Inc.
    OpenGL renderer string: Mesa DRI R600 (RS780 9614) 20090101 TCL DRI2
    OpenGL version string: 1.4 (2.0 Mesa 7.8-devel)
    OpenGL extensions:...
    at glxinfo. Also says
    "direct rendering: No"
    with this hack.
    Whats wrong?

    you have to remove fglrx (or workaround its libGL)

    I don't have fglrx for the months. And removed it already.
    And I can verify that my libGL is from mesa trunk.

    I run glxinfo utility with strace and see that:
    open("/home/compile/svn/gallium/lib64/gallium/r600_dri.so", O_RDONLY) = 4
    and doesn't try to open any other r600_dri.so,
    So I think radeong_dri.so initiated successfully but gallium doesn't want to run I think.
    Weird.

    AFAIK, no work has started on the r600 gallium driver. It's only the r300g driver that's usable, and I believe it covers archs up to r500.

    So is radeong just common code between r300g and the forthcoming r600g?

    The git pull ***** command doesn't seem to work on Ubuntu Karmic. Any tips for a git non-expert?
