This squashes all the radv development up until now into one for merging. History can be found: https://github.com/airlied/mesa/tree/semi-interesting This requires llvm 3.9 and is in no way considered a conformant vulkan implementation. It can run a number of vulkan applications, and supports all GPUs using the amdgpu kernel driver. Thanks to Intel for providing anv and spirv->nir, and Emil Velikov for reviewing build integration. Parts of this are: Reviewed-by: Nicolai Hähnle <nicolai.haehnle@amd.com> Acked-by: Edward O'Callaghan <funfunctor@folklore1984.net> Authors: Bas Nieuwenhuizen and Dave Airlie Signed-off-by: Dave Airlie <airlied@redhat.com>
