    perf metric: Directly use counts rather than saved_value · 37cc8ad7
    Ian Rogers authored
    Bugs with double aggregation have been introduced because of
    aggregation of counters and again with saved_value. Remove the generic
    metric use-case. Update parse-metric and pmu-events tests to update
    aggregate rather than saved_value counts.
