+vhost event idx interrupt modei with CBDMA test plan
+====================================================
+
+Description
+===========
+
+Vhost event idx interrupt need test with l3fwd-power sample with CBDMA channel,
+send small packets from virtio-net to vhost side, check vhost-user cores can be
+wakeup status，and vhost-user cores should be sleep status after stop sending
+packets from virtioside.
+
+.. note::
+
+ 1.For packed virtqueue virtio-net test, need qemu version > 4.2.0 and VM kernel version > 5.1, and packed ring multi-queues not support reconnect in qemu yet.
+ 2.For split virtqueue virtio-net with multi-queues server mode test, better to use qemu version >= 5.2.0, dut to qemu(v4.2.0~v5.1.0) exist split ring multi-queues reconnection issue.
+ 3.Kernel version > 4.8.0, mostly linux distribution don't support vfio-noiommu mode by default,
+ so testing this case need rebuild kernel to enable vfio-noiommu.
+ 4.When DMA devices are bound to vfio driver, VA mode is the default and recommended. For PA mode, page by page mapping may exceed IOMMU's max capability, better to use 1G guest hugepage.
+ 5.DPDK local patch that about vhost pmd is needed when testing Vhost asynchronous data path with testpmd.
+
+Prerequisites
+=============
+Topology
+--------
+Test flow: Virtio-net --> Vhost-user
+
+General set up
+--------------
+1. Compile DPDK::
+
+ # CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=static <dpdk build dir>
+ # ninja -C <dpdk build dir> -j 110
+ For example:
+ CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=static x86_64-native-linuxapp-gcc
+ ninja -C x86_64-native-linuxapp-gcc -j 110
