AmpereOne CPPC CPUFreq Schedutil vs. Performance Governor Benchmarks
Similar to the ACPI CPUFreq and AMD/Intel P-State CPU frequency scaling driver and scaling governor benchmarks and power efficiency comparisons I routinely do on Phoronix, when recently having the Supermicro AmpereOne server in the lab with the 192-core A192-32X processor, I carried out some CPPC CPUFreq schedutil vs. performance governor benchmarks for curiosity and reference purposes while looking at the performance and power efficiency.
