20 * The kernel collects the number of events it couldn't send in a stretch and
21 * when possible sends this number in a PERF_RECORD_LOST event. The number of
22 * such "chunks" of lost events is stored in .nr_events[PERF_EVENT_LOST] while
23 * total_lost tells exactly how many events the kernel in fact lost, i.e. it is
24 * the sum of all struct lost_event.lost fields reported.
25 *
26 * The total_period is needed because by default auto-freq is used, so
27 * multipling nr_events[PERF_EVENT_SAMPLE] by a frequency isn't possible to get
28 * the total number of low level events, it is necessary to to sum all struct
29 * sample_event.period and stash the result in total_period.
