Hence, the well known sched:sched_wakeup and sched:sched_switch tracepoints are not always enough to precisely explain the behavior of a deadline task with respect to the task's period, deadline and runtime consumption. This patch series implements tracepoints for the following deadline scheduler points of interest: - sched:sched_deadline_replenish: Informs the periodic runtime replenishment of a deadline task. - sched:sched_deadline_yield: Informs that a deadline task called sched_yield(), and will wait for the next period. - sched:sched_deadline_throttle: Informs that a task consumed all its available runtime and was throttled. - sched:sched_deadline_block: Informs that a deadline task went to sleep waiting to be awakened by another task.
