Deadline tasks behave differently of other tasks because deadline task's also depend on their period, deadline and runtime.
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.
Daniel Bristot de Oliveira (3): sched: Move deadline container_of() helper functions into sched.h sched/deadline: Tracepoints for deadline scheduler tools lib traceevent: Implements '%' operation
Steven Rostedt (Red Hat) (1): tracing: Add __print_ns_to_secs() and __print_ns_without_secs() helpers
