  • Ticket #4545

    • Property Summary changed from The SMP EDF scheduler has to better check the affinity set of a thread to The SMP EDF scheduler can only support more restricted affinity sets of a thread
  • Ticket #4545 – Description

    initial v1  
    1 The SMP EDF scheduler supports a one-to-one and one-to-all thread to processor affinity. Currently it accepts affinity sets which are a proper subset of the online processor containing at least two processors owned by the scheduler. In this case it sets a one-to-one thread to processor affinity. This leads to undefined behaviour if a processor is removed since the higher level check in rtems_scheduler_remove_processor() does not account for this implementation detail.
