So first of all, this patch alone doesn't make sense. You should submit
it in a patch-set that enabled IOMMUv2 performance counters for the
end-user. This means together with the PMU implementation and tools

Further I don't see how this patch is specific to Family 15h Models
10h-1Fh as described in the subject-line.

Any comments on these two points?
