I think the PVRs need work.

You have:

+004e0100,1,power9.json,core
+004e0000,1,power9.json,core

The first is P9 DD1, but the second doesn't exist. We have it in the
kernel, but with a mask of 0xffff0000. From memory the perf code doesn't
do any masking or anything fancy, it looks for an exact match.

So for starters you should probably drop that one and add 0x004e1200 and
0x004e0200.
