[VV]: I had a question on the eventdev initialization API in the above
multi-process setting. The following are the objects and API to init each of
them. For each of these can you confirm whether it needs to be called in the
PRIMARY process only or even the SECONDARY process must call these. The reason
for the question is that the shared memory must be safely initialized once.
Event device itself: rte_event_dev_configure, rte_event_dev_start
Ports: rte_event_port_setup
Queues: rte_event_queue_setup
Port-Queue-Links: rte_event_port_link
I don't think it matters if those calls are made from the primary or
secondary process. Please note however, those call are not thread-safe,
so external synchronization is required the calls are made from multiple
threads/processes.
