In CXL-land at least, I don't think it is our intent to keep spec revisions, sections, tables updated in general. That makes me think the only places where this patch should reference 3.1 is for the new items you added. All the extra spec updates can be omitted. Maybe perf folks are different about this? It's a nit.

I would say unless you are working in a specific part and updating that register block or adding a new definitions I would just leave it alone. Otherwise it's a lot of code churn. Will take that spelling correction though. > > Thanks, > Davidlohr >

I will send a v2 then only updating comments in the event groups where new events are added (and the typo fix).
