Subject: [dts] [PATCH V1 1/3] test_plans/vhost_cbdma_test_plan: modify test plan
Date: Thu, 9 Sep 2021 15:48:38 +0800 [thread overview]
Message-ID: <20210909074838.22153-1-weix.ling@intel.com> (raw)
1.Add client mode to start vhost and server mode to start virtio in case
1 and case 3.
2.Add new test case 6 and 7.
