Because in print_aggr, aggr_get_id needs index (not cpu id) to find core/pkg id. Also, evsel cpu maps should be used to get aggregated id. Here is an example. Counting events cycles,uncore_imc_0/cas_count_read/. (Uncore event has cpumask 0,18) "perf stat -e cycles,uncore_imc_0/cas_count_read/ -C0,18 --per-core sleep 2" Without this patch, it failes to get CPU 18 result.
