score: Fix CPU context usage on SMP We must not alter the is executing indicator in _CPU_Context_Initialize() since this would cause an invalid state during a self restart. The is executing indicator must be valid at creation time since otherwise _Thread_Kill_zombies() uses an undefined value for not started threads. This could result in a system life lock.

8:31 AM Changeset in rtems [38b59a6]4.11 by Sebastian Huber <sebastian.huber@…>
score: Implement forced thread migration The current implementation of task migration in RTEMS has some implications with respect to the interrupt latency. It is crucial to preserve the system invariant that a task can execute on at most one processor in the system at a time. This is accomplished with a boolean indicator in the task context. The processor architecture specific low-level task context switch code will mark that a task context is no longer executing and waits that the heir context stopped execution before it restores the heir context and resumes execution of the heir task. So there is one point in time in which a processor is without a task. This is essential to avoid cyclic dependencies in case multiple tasks migrate at once. Otherwise some supervising entity is necessary to prevent life-locks. Such a global supervisor would lead to scalability problems so this approach is not used. Currently the thread dispatch is performed with interrupts disabled. So in case the heir task is currently executing on another processor then this prolongs the time of disabled interrupts since one processor has to wait for another processor to make progress. It is difficult to avoid this issue with the interrupt latency since interrupts normally store the context of the interrupted task on its stack. In case a task is marked as not executing we must not use its task stack to store such an interrupt context. We cannot use the heir stack before it stopped execution on another processor. So if we enable interrupts during this transition we have to provide an alternative task independent stack for this time frame. This issue needs further investigation.

Allow Scheduler Simulator to "defer dispatch" until controlled This is needed to prevent a semaphore delete from triggering a preempt and breaking the mutex is owner debug check. Technically we are running the same thread until the API call returns. But from an RTEMS internals perspective, it was preempted at the _Object_Put(). When understanding this patch, it is important to remember that the Scheduler Simulator is single threaded and faking out RTEMS. This is one place where RTEMS would have preempted to a thread and when we returned to rtems_semaphore_delete(), the _Object_Put() call would have been made by the correct thread.
