Currently, the initial scheduler is round robin and preempts the current running task when the RTC fires a interrupt. We would like to improve this by:

  • Adding time slices to tasks, e.g. will preempt after 10ms instead of whatever the interrupt is set to.
  • Add the ability for a task to preempt itself, e.g. via a syscall.
  • Maybe add priorities to tasks
  • Only run the idle task when there are no tasks to run
  • Add task termination
  • Add more queues for:
    • Ready queue
    • Waiting: I/O / Sleep
