FWIW, that should be relatively easy to do in mesa/src/gallium/winsys/radeon/drm/radeon_drm_bo.c / libdrm/amdgpu/amgpu_vamgr.c by making every BO's userspace GPUVM address range larger than the BO size. The question is whether that can be enabled all the time or only for debugging, since it might cause the VM page tables to be less compact. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
