Looking to issue with issue with odp_scheduling.c
Problem can be described with following code:
Each cpu does this:
1. code allocs some events and place them to queue.
2. odp_schedule_pause();
3. odp_schedule_multi() put them back to queue.
4. odp_schedule_resume();
5. odp_barrier_wait(&globals->barrier);
6. clear_sched_queues();
static void clear_sched_queues(void)
{
odp_event_t ev;
int cnt = 0;
while (1) {
ev = odp_schedule(NULL, ODP_SCHED_NO_WAIT);
if (ev == ODP_EVENT_INVALID)
break;
odp_event_free(ev);
cnt++;
}
printf("clear %d\n", cnt);
}
Now I see that some threads inside clear_sched_queues() clear more or
less events. But all of them exits because invalid queue was returned.
I.e. there are some events still in scheduler.
If I call clear_sched_queues() 2 or 3 times rest of events freeing.
Which looks like we have a race between threads somewhere...
Maxim.
