Has MQX ever supported non-preemptive scheduling?

MQX supports preemptive scheduling with a priority based and Round Robin priority based preemptive scheduling. The MQX LTS only supports a Preemptive Round Robin policy.

Has MQX ever supported a non-preemptive scheduler or policy?

Hello,

Sorry if I misunderstood your question, MQX classic supports these policies:

• FIFO (also called priority-based preemptive) scheduling is a core component - the active task is the highest-priority task that has been ready the longest.

• Round robin (also called time slice) scheduling is a core component - the active task is the highest-priority task that has been ready the longest without consuming its time slice.

• Explicit scheduling (using task queues) is an optional component - you can use task queues to explicitly schedule tasks or to create more complex synchronization mechanisms. Because task queues provide minimal functionality, they are fast. An application can specify a FIFO or round robin scheduling policy when it creates the task queue.

To providing a scheduling mechanism, task queues provide a simple and efficient way to synchronize tasks. You can suspend tasks in the task queue and remove them from the task queue.

MQX Lite only supports priority based pre-emptive scheduler.

Please let me know if this helps!!

Have a great day,
Sol
