Hi Joerg,
I see your point(s). First, to the second point, I
should (and will) add a check to the AMD Family/Model coupled to this change.
Also, I will append the patch(es) to include the perf IOMMU PMU so that this
change is put into context.
Thanks for your time and advise.
Best Regards,
Steve

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 support.
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?
Cheers,
Joerg
