A Dlibperf-sampling.txt34 It requires root access, because it uses hardware cycles event.
36 The `sampling.c` example profiles/samples all CPUs with hardware cycles, in a
80 Once the setup is complete we start by defining cycles event using the `struct perf_event_attr`:
107 Now we create libperf's event list, which will serve as holder for the cycles event:
118 We create libperf's event for the cycles attribute we defined earlier and add it to the list:
124 56 fprintf(stderr, "failed to create cycles\n");
158 From this moment the cycles event is sampling.
