| Popis: | Fixed-Priority Scheduling with Deferred Preemption (FPDS) is a middle ground between Fixed-Priority Pre-emptive Scheduling and Fixed-Priority Non-preemptive Scheduling, and offers advantages with respect to context switch overhead and resource access control. In this paper we present our work on extending the real-time operating system RTAI/Linux with support for FPDS. We give an overview of possible alternatives, describe our design choices and implementation, and verify through a series of measurements that indicate that a FPDS implementation in a real-world RTOS is feasible with minimal overhead. |
