Subject: [dpdk-dev] [PATCH v4 0/2] vhost: support inflight share memory protocol feature
Date: Thu, 1 Aug 2019 04:40:48 +0800 [thread overview]
Message-ID: <20190731204050.40633-1-jin.yu@intel.com> (raw)
In-Reply-To: <20190725212335.9675>
This patches introduces two new messages VHOST_USER_GET_INFLIGHT_FD
and VHOST_USER_SET_INFLIGHT_FD to support transferring a shared
buffer between qemu and backend. This shared buffer is used to process
inflight I/O when backend reconnect
Now It can both support split and packed ring. The example code show
how these APIs work and the test has passed.
