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 <[email protected]>
