Hi!
Is there a way to detect (and prevent) the CPU overload in RT thread?
I've found no solutions in the archive.
Would something like this work?
while(1) {
ret = pthread_wait_np();
start_time = gethrtime();
if (overload++) {
suspend thread!
}
// Do some RT work.
rt_step();
rt_step_count++;
rt_task_spent_time += gethrtime() - start_time;
overload--;
}
If the rt_step takes too long to finish, what exactly happens?
The idea is to skip (miss) the overload--;
Is there any better solution to this overloading problem?
