Name:State based event timekeeping...* The basic idea is to use event->state to determine which (if any) time* fields to increment with the current delta. This means we only need to* update timestamps when we change state or when they are explicitly requested
Proto:static __always_inline enum perf_event_state __perf_effective_state(struct perf_event *event)
Type:enum perf_event_state
Parameter:
| Type | Parameter | Name |
|---|---|---|
| struct perf_event * | event |
| 611 | leader = group_leader |
| 613 | If state <= PERF_EVENT_STATE_OFF Then Return state |
| 616 | Return state |
| Name | Describe |
|---|---|
| __perf_update_times | |
| perf_install_in_context | Attach a performance event to a context.* Very similar to event_function_call, see comment there. |
