Open Source Graphics 101: Getting Started - Boris Brezillon, Collabora

Open Source Graphics 101: Getting Started - Boris Brezillon, Collabora GPUs are complex beasts, especially when you come from the CPU world and don't know about all those GPU-specific concepts, or what massively parallel and deeply pipelined computing implies. Throughout this talk, we will try to give a rough overview of some basic concepts (GPU pipeline stages, shaders, ...), how they are exposed to users (APIs like OpenGL, Vulkan or DirectX) and provide some extra details about the standard open-source stack providing those APIs (Mesa).
