This is a pipeline queue test case that aims at testing the following: 1. Measure the end-to-end performance of an event dev with a ethernet dev. 2. Maintain packet ordering from Rx to Tx. The pipeline queue test configures the eventdev with Q queues and P ports, where Q is (nb_ethdev * nb_stages) + nb_ethdev and P is nb_workers. The user can choose the number of workers and number of stages through the --wlcores and the --stlist application command line arguments respectively. The probed ethernet devices act as producer(s) for this application. The ethdevs are configured as event Rx adapters that enables them to injects events to eventdev based the first stage schedule type list requested by the user through --stlist the command line argument. Based on the number of stages to process(selected through --stlist), the application forwards the event to next upstream queue and when it reaches last stage in the pipeline if the event type is ATOMIC it is enqueued onto ethdev Tx queue else to maintain ordering the event type is set to ATOMIC and enqueued onto the last stage queue. On packet Tx, application increments the number events processed and print periodically in one second to get the number of events processed in one second. Note: The --prod_type_ethdev is mandatory for running the application. Example command to run pipeline queue test: sudo build/app/dpdk-test-eventdev -c 0xf -s 0x8 --vdev=event_sw0 -- \ --test=pipeline_queue --wlcore=1 --prod_type_ethdev --stlist=ao Signed-off-by: Pavan Nikhilesh <pbhagavatula@caviumnetworks.com> Acked-by: Harry van Haaren <harry.van.haaren@intel.com>
