ctx_resched | We want to maintain the following priority of scheduling:* - CPU pinned (EVENT_CPU | EVENT_PINNED)* - task pinned (EVENT_PINNED)* - CPU flexible (EVENT_CPU | EVENT_FLEXIBLE)* - task flexible (EVENT_FLEXIBLE) |
ctx_sched_out | |
perf_pmu_sched_task | This function provides the context switch callback to the lower code* layer. It is invoked ONLY when the context switch callback is enabled.* This callback is relevant even to per-cpu events; for example multi event |
perf_event_context_sched_in | |
perf_adjust_freq_unthr_context | mbine freq adjustment with unthrottling to avoid two passes over the* events. At the same time, make sure, having freq events does not change* the rate of unthrottling as that would introduce bias. |
