[PATCH] D94395: [X86] AMD Zen 3 Scheduler Model

[Ganesh Gopalasubramanian via Phabricator via llvm-commits]

GGanesh added a comment.

Regarding the pipe events, the patch in kernel.org had just copy pasted events from zen1 and zen2. Apparently, I learnt that these events are restricted and at present not really ready for public for znver3. That is what is reflected in the kernel patch as well. If we notice, PMCx000 is incorrectly mapped and doesn't really count the 6 pipes. 
Is there any workaround that you guys suggest. I understand that these are pfm counters and are dynamic in nature. However, for the model, (at least for the throughput numbers) shall I publish our internal numbers running the internally enabled libpfm4 library? This is restricted in its immediate purpose which I understand however at present it may act as a work around for the throughput and llvm-mca numbers.
I am going through the modifications\corrections made in the by @lebedev.ri  in the meantime.
