Here's the relevant code from odp_crypto.c:
/* If specified during creation post event to completion queue */
if (ODP_QUEUE_INVALID != session->compl_queue) {
odp_event_t completion_event;
odp_crypto_generic_op_result_t *op_result;
/* Linux generic will always use packet for completion event */
completion_event = odp_packet_to_event(params->out_pkt);
_odp_buffer_event_type_set(
odp_buffer_from_event(completion_event),
ODP_EVENT_CRYPTO_COMPL);
/* Asynchronous, build result (no HW so no errors) and send it*/
op_result = get_op_result_from_event(completion_event);
op_result->magic = OP_RESULT_MAGIC;
op_result->result = local_result;
if (odp_queue_enq(session->compl_queue, completion_event)) {
odp_event_free(completion_event);
return -1;
}
/* Indicate to caller operation was async */
*posted = 1;
} else {
/* Synchronous, simply return results */
if (!result)
return -1;
*result = local_result;
/* Indicate to caller operation was sync */
*posted = 0;
}
return 0;
So crypto completion events are piggybacked onto packets since you need a
packet as the result of the operation. odp_event_type() should return
ODP_CRYPTO_COMPL for this event.
Do you have the snippet of code that's seeing something different you can
share?
