Some drivers may support burst functionality only with the packets having same destination device and queue. The flag `RTE_EVENT_ETH_TX_ADAPTER_ENQUEUE_SAME_DEST` can be used to indicate this so the underlying driver, for drivers to utilize burst functionality appropriately. Signed-off-by: Nipun Gupta --- Changes in v2: - have separate internal API in tx adapter for sending burst packets to same eth dev, queue pair on the basis of the passed flag - fix compilation of examples/eventdev_pipeline/ app/test-eventdev/test_pipeline_common.h | 6 +++--- .../prog_guide/event_ethernet_tx_adapter.rst | 3 ++- .../eventdev_pipeline/pipeline_worker_tx.c | 2 +- .../rte_event_eth_tx_adapter.h | 19 +++++++++++++++++-- lib/librte_eventdev/rte_eventdev.c | 12 ++++++++++++ lib/librte_eventdev/rte_eventdev.h | 9 +++++++++ 6 files changed, 44 insertions(+), 7 deletions(-) diff --git a/app/test-eventdev/test_pipeline_common.h b/app/test-eventdev/test_pipeline_common.h index 0440b9e29..6e73c6ab2 100644 --- a/app/test-eventdev/test_pipeline_common.h +++ b/app/test-eventdev/test_pipeline_common.h @@ -106,7 +106,7 @@ pipeline_event_tx(const uint8_t dev, const uint8_t port, struct rte_event * const ev) { rte_event_eth_tx_adapter_txq_set(ev->mbuf, 0); - while (!rte_event_eth_tx_adapter_enqueue(dev, port, ev, 1)) + while (!rte_event_eth_tx_adapter_enqueue(dev, port, ev, 1, 0)) rte_pause(); } @@ -116,10 +116,10 @@ pipeline_event_tx_burst(const uint8_t dev, const uint8_t port, { uint16_t enq; - enq = rte_event_eth_tx_adapter_enqueue(dev, port, ev, nb_rx); + enq = rte_event_eth_tx_adapter_enqueue(dev, port, ev, nb_rx, 0); while (enq < nb_rx) { enq += rte_event_eth_tx_adapter_enqueue(dev, port, - ev + enq, nb_rx - enq); + ev + enq, nb_rx - enq, 0); } } diff --git a/doc/guides/prog_guide/event_ethernet_tx_adapter.rst b/doc/guides/prog_guide/event_ethernet_tx_adapter.rst index 192f9e1cf..a8c13e136 100644 --- a/doc/guides/prog_guide/event_ethernet_tx_adapter.rst +++ b/doc/guides/prog_guide/event_ethernet_tx_adapter.rst @@ -137,11 +137,12 @@ should use the ``rte_event_enqueue_burst()`` function. if (cap & RTE_EVENT_ETH_TX_ADAPTER_CAP_INTERNAL_PORT) { event.mbuf = m; + eq_flags = 0; m->port = tx_port; rte_event_eth_tx_adapter_txq_set(m, tx_queue_id); - rte_event_eth_tx_adapter_enqueue(dev_id, ev_port, &event, 1); + rte_event_eth_tx_adapter_enqueue(dev_id, ev_port, &event, 1, eq_flags); } else { event.queue_id = qid; /* event queue linked to adapter port */ diff --git a/examples/eventdev_pipeline/pipeline_worker_tx.c b/examples/eventdev_pipeline/pipeline_worker_tx.c index 8961cd656..a0f40c27c 100644 --- a/examples/eventdev_pipeline/pipeline_worker_tx.c +++ b/examples/eventdev_pipeline/pipeline_worker_tx.c @@ -40,7 +40,7 @@ worker_tx_pkt(const uint8_t dev, const uint8_t port, struct rte_event *ev) { exchange_mac(ev->mbuf); rte_event_eth_tx_adapter_txq_set(ev->mbuf, 0); - while (!rte_event_eth_tx_adapter_enqueue(dev, port, ev, 1)) + while (!rte_event_eth_tx_adapter_enqueue(dev, port, ev, 1, 0)) rte_pause(); } diff --git a/lib/librte_eventdev/rte_event_eth_tx_adapter.h b/lib/librte_eventdev/rte_event_eth_tx_adapter.h index c848261c4..f552b6023 100644 --- a/lib/librte_eventdev/rte_event_eth_tx_adapter.h +++ b/lib/librte_eventdev/rte_event_eth_tx_adapter.h @@ -300,6 +300,11 @@ rte_event_eth_tx_adapter_txq_get(struct rte_mbuf *pkt) int rte_event_eth_tx_adapter_event_port_get(uint8_t id, uint8_t *event_port_id); +#define RTE_EVENT_ETH_TX_ADAPTER_ENQUEUE_SAME_DEST 0x1 +/**< This flag is used when all the packets enqueued in the tx adapter are + * destined for the same Ethernet device, queue pair. + */ + /** * Enqueue a burst of events objects or an event object supplied in *rte_event* * structure on an event device designated by its *dev_id* through the event @@ -324,6 +329,10 @@ rte_event_eth_tx_adapter_event_port_get(uint8_t id, uint8_t *event_port_id); * The number of event objects to enqueue, typically number of * rte_event_port_attr_get(...RTE_EVENT_PORT_ATTR_ENQ_DEPTH...) * available for this port. + * @param flags + * See RTE_EVENT_ETH_TX_ADAPTER_ENQUEUE_ flags. + * #RTE_EVENT_ETH_TX_ADAPTER_ENQUEUE_SAME_DEST signifies that all the packets + * which are enqueued are destined for the same Ethernet device, queue pair. * * @return * The number of event objects actually enqueued on the event device.
