Some performance counter is missing in the new Arch?

Hi,

I can find there are some performance counter existing in the old chip but is missing in the new arch (RDNA).

Such as:

PAPixelsPerTriangle

But the RDNA chip doesn't have this perf counter:

Thanks,

Thanks for bringing this to our attention. I had forgotten all about PAPixelsPerTriangle as something that we used to support, and I do agree it would be a useful counter to bring back. I'll include this among the set of counters that we want to revisit and see if it will be possible to bring back in a future release.
