Constant MAX_EQPD_COMBINATIONS 

const MAX_EQPD_COMBINATIONS: u128 = 100_000;

Upper bound on the number of equivalence performance domain combinations to consider, to keep the number of combinations manageable. The performance domains of a processor may not collapse into a few equivalence performance domains – per-core binning, for one, could give every core its own performance table.
