Subject: [PATCH v9 1/4] ethdev: add API for mbufs recycle mode
Date: Wed,  2 Aug 2023 16:08:09 +0800	[thread overview]
Message-ID: <20230802080812.559463-2-feifei.wang2@arm.com> (raw)
In-Reply-To: <20230802080812.559463-1-feifei.wang2@arm.com>

Add 'rte_eth_recycle_rx_queue_info_get' and 'rte_eth_recycle_mbufs'
APIs to recycle used mbufs from a transmit queue of an Ethernet device,
and move these mbufs into a mbuf ring for a receive queue of an Ethernet
device. This can bypass mempool 'put/get' operations hence saving CPU
cycles.

For each recycling mbufs, the rte_eth_recycle_mbufs() function performs
the following operations:
- Copy used *rte_mbuf* buffer pointers from Tx mbuf ring into Rx mbuf
ring.
- Replenish the Rx descriptors with the recycling *rte_mbuf* mbufs freed
from the Tx mbuf ring.

+* **Add mbufs recycling support. **
+
+  Added ``rte_eth_recycle_rx_queue_info_get`` and ``rte_eth_recycle_mbufs``
+  APIs which allow the user to copy used mbufs from the Tx mbuf ring
+  into the Rx mbuf ring. This feature supports the case that the Rx Ethernet
+  device is different from the Tx Ethernet device with respective driver
+  callback functions in ``rte_eth_recycle_mbufs``.
