As core part of heuristic merged to for-next tree, I send another patch with shannon entropy calculation, as that metric will cover another part of cases. That also will cover most of silesia corpus data. P.S. i reverse ported it, so: https://github.com/Nefelim4ag/companalyze For now that only for guess kernel counters for specific data, i.e. no policy logic. Only RAW counters. To know if tunning needed on specific data case and easy check that heuristic see for that data.
