Subject: [dpdk-dev] [PATCH 0/2] support inflight share memory protocol feature
Date: Tue, 9 Jul 2019 02:39:57 +0800 [thread overview]
Message-ID: <20190708183959.50293-1-jin.yu@intel.com> (raw)
This patches series 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.
The example show how these new APIs work.
