    perf test: Roundtrip name, don't assume 1 event per name · a8af6e48
    Ian Rogers authored
    Opening hardware names and a legacy cache event on a hybrid PMU opens
    it on each PMU. Parsing and checking indexes fails, as the parsed
    index is double the expected. Avoid checking the index by just
    comparing the names immediately after the parse.
    
    This change removes hard coded hybrid logic and removes assumptions
    about the expansion of an event. On hybrid the PMUs may or may not
    support an event and so using a distance isn't a consistent solution.
