Documentation/gpu: Add documentation about ring buffer

2025-12-08T18:56:32+00:00

AMDGPU heavily relies on ring buffers to manage its components; as a result, it has an elaborate mechanism of operation with multiple details around it. This commit introduces new documentation on ring buffers, detailing their management and expanding the explanation of Enforce isolation. Finally, this commit also adds the documentation available in the amdgpu_ring.c file to it.
