As you may know, a few of us are experimenting with multi-runqueue scheduler implementations. One area of concern is where to place realtime tasks. It has been my assumption, that POSIX RT semantics require a specific ordering of tasks such as SCHED_FIFO and SCHED_RR. To accommodate this ordering, I further believe that the simplest solution is to ensure that all realtime tasks reside on the same runqueue. In our MQ scheduler we have a separate runqueue for all realtime tasks. The problem is that maintaining a separate realtime runqueue is a pain and results in some fairly complex/ugly code.
Since I'm not a realtime expert, I would like to ask if my assumption about strict ordering of RT tasks is accurate. Also, is anyone aware of other ways to approach this problem?
