I am working with RTEMS 5 - SMP enabled. I have 2 questions. 1) I am trying to synchronize the rate monotonic timer(id2) of a thread with the rate monotonic timer(id1) of another thread. To do that I have the following lines in one of the threads.
rtems_rate_monotonic_get_status(id1, remaining_time) rtems_rate_monotonic_period(id2, deadline - remaining_time) Inorder for this to work correctly, the thread should not be pre-empted between the two function calls. When I tried to use rtems_interrupt_local_disable(), it creates a runtime error INTERNAL_ERROR_BAD_THREAD_DISPATCH_ENVIRONMENT. Is there another way to temporarily disable thread pre-emption until the two functions completes execution? 2) What would be the best way to implement a thread in RTEMS that has a Deadline != Period. One way to do it is by using multiple rate monotonic timers inside each thread. But what would be a better implementation when the outermost timer(period) is common for all the threads?
