As you are touching this file can you change following things:
Need to increase the delay to a value similar to other tc.
service_lcore_running_check(void)
{
uint64_t tick = service_tick;
- rte_delay_ms(SERVICE_DELAY * 10);
+ rte_delay_ms(100);
/* if (tick != service_tick) we know the lcore as polled the service */
return tick != service_tick;
}
As service_mt_unsafe_poll and service_mt_safe_poll use the same function body and
are called one after the other we need to wait for them to complete before
proceeding to the next tc i.e service_mt_unsafe_poll -> wait for the cores to
complete -> service_mt_safe_poll else it will lead to unintended side effects.
