[dpdk-dev] Question about rte_manage_timer() and eal_intr_handle_interrupts

[Somnath Kotur]

Hi Anatoly/keith,
                     I just tried using rte_eal_alarm_set() in the driver
like so:

rte_eal_alarm_set(US_PER_S * 2, timer0_cb, (void *)data);

The moment i start this off, i stop getting async events/interrupt
notifications in my driver ...I'm hitting the same problem as it was before
with rte_timer_manage() as well.
What is going wrong here ? Something we are missing ?

Thanks
Som
