Revision 9aba0adae8c773ba0c0adc7c4d97768e044166cb authored by Ian Rogers on 11 November 2021, 00:21:09 UTC, committed by Arnaldo Carvalho de Melo on 13 November 2021, 21:11:50 UTC
Events like uncore_imc/cas_count_read/ on Skylake open multiple events and then aggregate in the metric leader. To determine the average value per event the number of these events is needed. Add a source_count function that returns this value by counting the number of events with the given metric leader. For most events the value is 1 but for uncore_imc/cas_count_read/ it can yield values like 6. Add a generic test, but manually tested with a test metric that uses the function.
