We are currently running some experiments with RTEMS in SMP and were
faced with some problems. We were hoping someone with a better
understanding of the operating system mechanisms could help us figure
out what to do.
We are using the EDF (Earliest Deadline First) scheduler for RTEMS-SMP
and the Rate Monotonic Manager.
We were trying to run some periodic tasks that have a constrained
deadline. (e.g., Task1 - Deadline: 30 ticks - Period: 1000 ticks)
The use case of constrained deadlines is currently not supported. I
think we would have to modify the rate monotonic objects to support it
or create a new object. You have to combine a normal timer for the
period with a deadline initialization at period begin.
