    What about OpenGL support in r600g ?
    Reading GL3.txt, it looks like r600g supports OpenGL 3.2, GLSL 1.50 and Geometry Sharders but it's not the case in fact.

      I believe that r600g is still missing GLSL 1.50 in order to support OpenGL 3.2.

      If you head to a terminal, try:
      MESA_GLSL_VERSION_OVERRIDE=150 glxinfo

      On my radeonsi (7850) with a 2-week old mesa git checkout (currently bisecting something), I get:
      Code:
      OpenGL vendor string: X.Org
      OpenGL renderer string: Gallium 0.4 on AMD PITCAIRN
      OpenGL core profile version string: 3.2 (Core Profile) Mesa 10.0.0-devel (git-2be85e2)
      OpenGL core profile shading language version string: 1.50

        Megadrivers seems to be in this release. Did it also break gallium drivers for pre-1.15 X servers, or only classic (Intel)?

          r200 mega driver loads fine here if xserver 1.14 is patched with:

            wooooo

            I was so excited for the OpenCL changes, but to enable them is not that easy...
            One need to recompile Mesa with the enable flag, ok not too hard.
            BUT, to do that you need latest libcl, ok easy.
            BUT, for that you need latest clang, and for mesa, llvm needs to be in shared mode.

            Somehow the combination of all of that is that I have not been able to get there yet...
            Even with all the beautiful pkgbuild in aur... Hmmmm

              I followed the wiki pages and it works.For llvm you have to enable shared mode or it wont work.
              I have built it this way (the disable docs i put there because i had some ocaml related build errors initiall, not sure its needed):
              Code:
              ./configure --enable-experimental-targets=R600 --enable-targets=x86_64 --enable-shared --disable-docs --enable-optimized
              Dont forget to clone clang too in the llvm git's tools folder.

                Thanks, I was trying to reuse existing pkgbuilds, but maybe I should have written mine instead

                  Well I managed to install everything, but a simple test from here http://wiki.tiker.net/OpenCLHowTo crashes...

                  I will try again with mesa-master, I only got llvm and libclc master with Mesa 10.2.
                  Let's see if that makes a difference.

                    No difference... :/
