Subject: [dts] [PATCH V2] test: add vhost/virtio pvp performance test based on qemu
Date: Wed, 21 Dec 2016 16:27:49 +0800	[thread overview]
Message-ID: <1482308869-9080-1-git-send-email-lei.a.yao@intel.com> (raw)

From: lei yao <lei.a.yao@intel.com>

The test case include 3 part:
1. virtio 0.95 performance test
virtio0.95 is the default version for qemu. Vector, normal, mergeable path will be tested on this version
2. Test vector performance on virtio 1.0.
