Only the AMD/mesa devs can reasonably deal with the insane complexity of the GL stack (linux(drm) + libdrm + llvm + mesa(GL) + xserver + xf86-video-amdgpu). But they won't be able to do anything if you don't run the latest git version of the code (linux + mesa) and provide an easily reproducible and free (as in free beer) case (or some AMD/mesa devs own your games). -------------------------------------------------------------------------------- I run such a 64bits system. If you can reproduce the issue with a free (as in free beer) game, I'll be pleased to test it to see if it happens on my system. or You would need to compile and run the following linux kernel: "git://people.freedesktop.org/~agd5f/linux branch", "amd-staging-drm-next" branch Unfortunately, Southern Islands hardware shader compiler is llvm, you would need to compile the latest git llvm-project (a massive pain). Idem for libdrm, mesa, the xserver, and the amdgpu xserver driver. -------------------------------------------------------------------------------- -- Sylvain _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
