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