Subject: [dpdk-dev] [PATCH 0/1] lib/vhost: support async dequeue for split ring
Date: Wed, 2 Jun 2021 08:31:09 +0000 [thread overview]
Message-ID: <20210602083110.5530-1-yuanx.wang@intel.com> (raw)
This patch implements asynchronous dequeue data path for split ring.
A new asynchronous dequeue function is introduced. With this function,
the application can try to receive packets from the guest with
offloading large copies to the DMA engine, thus saving precious CPU
cycles.
