We were previously relying on a side effect of the critical section in smp_process_pending_messages(): when exiting that section, it would process any pending deferred calls. Instead of relying on that, make the deferred invocations explicit by calling deferred_call_execute_pending() in exit_trap(). This ensures that deferred calls get processed before entering the scheduler at the end of exit_trap(). Since thread unblocking happens via deferred calls, the threads don't have to wait until the next scheduling opportunity when they could be ready *now*. :^) This was the main reason Tom's SMP branch ran slowly in non-SMP mode. |
