vm2vm vhost-user/virtio-pmd test plan
=====================================
-This test plan includes vm2vm mergeable, normal and vector_rx path test with virtio 0.95 and virtio 1.0,
-also add mergeable and normal path test with virtio 1.1. Specially, three mergeable path cases check the
-payload of each packets are valid by using pdump.
-Note: Blow cases 9-11 which have cbdma usage should add dpdk local path to support async vhostpmd.
+Description
+===========
-Test flow
+This test plan includes vm2vm mergeable, normal and vector_rx path test with virtio 0.95 and virtio 1.0.
+Since qemu 4.2.0, Packed virtqueue mergeable path and Packed virtqueue non-mergeable path can be supported.
+then also add mergeable and non-mergeable path test with virtio 1.1.
+
+For more about dpdk-testpmd sample, please refer to the DPDK docments:
+https://doc.dpdk.org/guides/testpmd_app_ug/run_app.html
+
+For virtio-user vdev parameter, you can refer to the DPDK docments:
+https://doc.dpdk.org/guides/nics/virtio.html#virtio-paths-selection-and-usage.
+
+Prerequisites
+=============
+
+Topology
+--------
+ Test flow: Virtio-pmd-->Vhost-user-->Testpmd-->Vhost-user-->Virtio-pmd
+
+Hardware
+--------
+ Supportted NICs: ALL
+
+Software
+--------
+ Trex:http://trex-tgn.cisco.com/trex/release/v2.26.tar.gz
+
+General set up
+--------------
+1. Compile DPDK::
+
+ # CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=<dpdk build dir>
+ # ninja -C <dpdk build dir> -j 110
+
+2. Get the PCI device ID and DMA device ID of DUT, for example, 0000:18:00.0 is PCI device ID, 0000:00:04.0, 0000:00:04.1 is DMA device ID::
+
+ <dpdk dir># ./usertools/dpdk-devbind.py -s
+
+ Network devices using kernel driver
+ ===================================
+ 0000:18:00.0 'Device 159b' if=ens785f0 drv=ice unused=vfio-pci
+
+ DMA devices using kernel driver
+ ===============================

-3. On VM1 and VM2, bind virtio device with vfio-pci driver::
-
- modprobe vfio
- modprobe vfio-pci
- echo 1 > /sys/module/vfio/parameters/enable_unsafe_noiommu_mode
- ./usertools/dpdk-devbind.py --force --bind=vfio-pci 0000:00:05.0
-
-4. Launch testpmd in VM1::
-
- ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 0x3 -n 4 -- -i --tx-offloads=0x00 --enable-hw-vlan-strip --txq=8 --rxq=8 --txd=1024 --rxd=1024 --max-pkt-len=9600 --rx-offloads=0x00002000
- testpmd>set mac fwd
- testpmd>start
-
-5. Launch testpmd in VM2 and send imix pkts, check imix packets can looped between two VMs for 1 mins and 8 queues all have packets rx/tx::
-
- ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 0x3 -n 4 -- -i --tx-offloads=0x00 --enable-hw-vlan-strip --txq=8 --rxq=8 --txd=1024 --rxd=1024 --max-pkt-len=9600 --rx-offloads=0x00002000
- testpmd>set mac fwd
- testpmd>set txpkts 64,256,512,1024,20000,64,256,512,1024,20000
- testpmd>start tx_first 32
- testpmd>show port stats all
- testpmd>stop
-
-6. Quit VM2 and relaunch VM2 with split ring::
-
- taskset -c 6-16 qemu-system-x86_64 -name vm1 -enable-kvm -cpu host -smp 9 -m 4096 \
- -object memory-backend-file,id=mem,size=4096M,mem-path=/mnt/huge,share=on \
- -numa node,memdev=mem -mem-prealloc -drive file=/home/osimg/ubuntu20-04.img \
- -chardev socket,path=/tmp/vm2_qga0.sock,server,nowait,id=vm2_qga0 -device virtio-serial \
- -device virtserialport,chardev=vm2_qga0,name=org.qemu.guest_agent.2 -daemonize \
- -monitor unix:/tmp/vm2_monitor.sock,server,nowait -device e1000,netdev=nttsip1 \
- -netdev user,id=nttsip1,hostfwd=tcp:127.0.0.1:6002-:22 \
- -chardev socket,id=char0,path=./vhost-net0 \
- -netdev type=vhost-user,id=netdev0,chardev=char0,vhostforce,queues=8 \
- -device virtio-net-pci,netdev=netdev0,mac=52:54:00:00:00:01,disable-modern=false,mrg_rxbuf=on,mq=on,vectors=40,csum=on,guest_csum=on,host_tso4=on,guest_tso4=on,guest_ecn=on,guest_ufo=on,host_ufo=on -vnc :10
-
-7. Bind virtio device with vfio-pci driver, launch testpmd in VM2 and send imix pkts, check imix packets can looped between two VMs for 1 mins and 8 queues all have packets rx/tx::
-
