Documentation/gpu: Add explanation about AMD Pipes and Queues Pipes and Queues are two common vocabulary that pervades discussions around amdgpu core features. The definition and explanation of those components are spread around multiple places in the code, mailing list, and Gitlab, which sometimes leads to the wrong interpretation of these concepts. This commit attempts to centralize the definition and explanation of Pipe and Queue from amdgpu perspective in a kernel doc. Most of the information in this doc was derived from: - https://lore.kernel.org/amd-gfx/CADnq5_Pcz2x4aJzKbVrN3jsZhD6sTydtDw=6PaN4O3m4t+Grtg@mail.gmail.com/T/#m9a670b55ab20e0f7c46c80f802a0a4be255a719d - https://gitlab.freedesktop.org/mesa/mesa/-/issues/11759 Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Rodrigo Siqueira <siqueira@igalia.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
