Hi,
In the odp_pktio validation – a pktio is created and it is configured
with a PKTIN queue.
Packets are then enqueued to the out queue of the device.
In the function *wait_for_packet***I think is an issue when an event
is received.
There is the following condition :
*if*(queue != ODP_QUEUE_INVALID)
ev = queue_deq_wait_time(queue, ns);
*else*
ev = odp_schedule(NULL, ns);
The *queue* that comes as input param, is the PKTIN queue which is a
scheduled queue.
As it can be noticed the queue_deq_wait_time will be called (PKTN
queue is valid) and there,
*an explicit dequeue operation will be performed on a scheduled queue
*which is not OK.
So a schedule would be proper instead of explicit dequeue.
A possible fix is to check for *queue type instead of validity*, and
if the queue is POLL then take the corresponding branch:
*if*(*odp_queue_type(*queue) == ODP_QUEUE_TYPE_POLL)
ev = queue_deq_wait_time(queue, ns);
*else*
ev = odp_schedule(NULL, ns);
Regards,
Radu
