After A Bumpy Cycle, AMD Performance Will Shine Brighter On Linux 5.11

On an AMD EPYC 7F52 box I've also been looking at the Linux 5.11 performance if using the ondemand governor rather than Schedutil. While most AMD boxes on newer Linux kernels are now defaulting to Schedutil on most distributions, Ondemand is the prior default for many distributions. The ondemand governor didn't regress on Linux 5.11 like Schedutil did where the AMD frequency invariance support is now utilized. But exciting is that it's looking like the patched CPUFreq is providing benefit under the ondemand governor too in some workloads.
