Just noticed that this one is not present at all in PPR 56176 Rev 3.06 - Jul 17, 2019 and that the umasks for the rest of the sub-counters in PMC0xAF are right shifted by one when compared to those in Zen1. As a result, the previous counter at umask 0x1 is no longer present.
I will update this counter to reflect what is documented in model 71h PPR 56176 Rev 3.06 - Jul 17, 2019.
