| * when possible sends this number in a PERF_RECORD_LOST event. The number of |
| * such "chunks" of lost events is stored in .nr_events[PERF_EVENT_LOST] while |
| * total_lost tells exactly how many events the kernel in fact lost, i.e. it is |
| * the sum of all struct lost_event.lost fields reported. |
| * |
| * The total_period is needed because by default auto-freq is used, so |
| * multipling nr_events[PERF_EVENT_SAMPLE] by a frequency isn't possible to get |
| * the total number of low level events, it is necessary to to sum all struct |
| * sample_event.period and stash the result in total_period. |
