Over the prior RFC v4 patches, there have just been some minor alterations and fixes to the code. New to the patch series are test results included for AMD EPYC 9004 "Genoa" with some staggering results: up to 44% faster than the current mainline kernel! With the ChaCha20-xiangshan benchmark, the time on that AMD EPYC Genoa test system drops from 50,868 ms to just 28,349 ms with cache aware scheduling. On older AMD EPYC Milan they didn't find any performance benefit. Meanwhile on Intel's own Sapphire Rapids server used for testing, they found Hackbench showing some benefit in select cases. Or for the ChaCha20-xiangshan up to a ~10% improvement. phoronix.com
