Lately, I have been part of multiple discussions around GPU recovery and other concepts associated with GFX/Compute. Most of the debate is spread around GitLab issues, emails, and some meeting conversations. This patchset aims to consolidate all that information into a single kernel-doc, which can be collaboratively improved and shared with other people.
In this series, you will find new amdgpu glossary entries, more details about the IPs' interconnections, and a description of the ring buffer. This series includes multiple SVG diagrams; for this reason, it might be good to apply this series locally. Finally, keep in mind that I tried to fill in some gaps between information, and hopefully, my description matches the reality.
