AMD has announce it will start rolling out in January an open source set of tools called GPUOpen. The "All Open" stack will contain open source modules for two parallel stacks, each containing modules for OpenGL graphics, motion video codecs, and OpenCL GPU computation. The "Professional/Gamer" stack will include the open source motion-video module and a closed source OpenGL module. Its final OpenCL module will support both OpenCL and Vulkan. Linux will gain access to a full open source, high-performance driver stack, with the only constraint being that developers must use Vulkan instead of the older OpenGL.
