[dts] [PATCH V4] test: add vhost/virtio pvp performance test
lei,yao
lei.a.yao at intel.com
Thu Dec 22 06:17:28 CET 2016
From: lei yao <lei.a.yao at intel.com>
The test case include 2 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.
Change in V4
The cmd is changed to based on self.target
