Subject: [dpdk-dev] [PATCH v3 2/5] lib/ring: add zero copy APIs
Date: Thu, 22 Oct 2020 23:43:40 -0500 [thread overview]
Message-ID: <20201023044343.13462-3-honnappa.nagarahalli@arm.com> (raw)
In-Reply-To: <20201023044343.13462-1-honnappa.nagarahalli@arm.com>
Add zero-copy APIs. These APIs provide the capability to
copy the data to/from the ring memory directly, without
having a temporary copy (for ex: an array of mbufs on
the stack). Use cases that involve copying large amount
of data to/from the ring can benefit from these APIs.

+ * @file
+ * @b EXPERIMENTAL: this API may change without prior notice
+ * It is not recommended to include this file directly.
+ * Please include <rte_ring_elem.h> instead.
+ *
+ * Ring Peek Zero Copy APIs
+ * These APIs make it possible to split public enqueue/dequeue API
+ * into 3 parts:
+ * - enqueue/dequeue start
+ * - copy data to/from the ring
+ * - enqueue/dequeue finish
+ * Along with the advantages of the peek APIs, these APIs provide the ability
+ * to avoid copying of the data to temporary area (for ex: array of mbufs
+ * on the stack).
+ *
+ * Note that currently these APIs are available only for two sync modes:
+ * 1) Single Producer/Single Consumer (RTE_RING_SYNC_ST)
+ * 2) Serialized Producer/Serialized Consumer (RTE_RING_SYNC_MT_HTS).
+ * It is user's responsibility to create/init ring with appropriate sync
+ * modes selected.
+ *
+ * Following are some examples showing the API usage.
+ * 1)
+ * struct elem_obj {uint64_t a; uint32_t b, c;};
+ * struct elem_obj *obj;
+ *
+ * // Create ring with sync type RTE_RING_SYNC_ST or RTE_RING_SYNC_MT_HTS
+ * // Reserve space on the ring
+ * n = rte_ring_enqueue_zc_bulk_elem_start(r, sizeof(elem_obj), 1, &zcd, NULL);
+ *
+ * // Produce the data directly on the ring memory
+ * obj = (struct elem_obj *)zcd->ptr1;
+ * obj.a = rte_get_a();
+ * obj.b = rte_get_b();
+ * obj.c = rte_get_c();
+ * rte_ring_enqueue_zc_elem_finish(ring, n);
+ *
+ * 2)
+ * // Create ring with sync type RTE_RING_SYNC_ST or RTE_RING_SYNC_MT_HTS
+ * // Reserve space on the ring
+ * n = rte_ring_enqueue_zc_burst_start(r, 32, &zcd, NULL);
+ *
+ * // Pkt I/O core polls packets from the NIC
+ * if (n == 32)
+ * nb_rx = rte_eth_rx_burst(portid, queueid, zcd->ptr1, 32);
+ * else
+ * nb_rx = rte_eth_rx_burst(portid, queueid, zcd->ptr1, zcd->n1);
+ *
+ * // Provide packets to the packet processing cores
+ * rte_ring_enqueue_zc_finish(r, nb_rx);
+ *
+ * Note that between _start_ and _finish_ none other thread can proceed
+ * with enqueue/dequeue operation till _finish_ completes.
