5 methology to break down CPU pipeline execution into 4 bottlenecks:
10 Traditionally this was implemented by events in generic counters
13 perf stat --topdown implements this.
15 Full Top Down includes more levels that can break down the
24 fixed counters and do not require generic counters. This allows
27 % perf stat -a --topdown -I1000
64 metric event, and allow user programs to read the performance counters.
94 int slots_fd = perf_event_open(&slots, 0, -1, -1, 0);
109 int metrics_fd = perf_event_open(&metrics, 0, -1, slots_fd, 0);
