Subject: [dts] [PATCH V1] test: add vhost/virtio pvp performance test based on qemu
Date: Tue, 20 Dec 2016 14:07:42 +0800 [thread overview]
Message-ID: <1482214062-7757-1-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 differnt qemu version. For exapmle: qemu2.5, qemu2.6, qemu2.7
3. Test vector performance on virtio 1.0.
