-vhost dequeue zero-copy test plan
-=================================
-
-Description
-===========
-
-Vhost dequeue zero-copy is a performance optimization for vhost, the copy in the dequeue path is avoided in order to improve the performance. The test cases cover split ring and packed ring.
-Notice:
-
-* All packed ring case need special qemu version.
-* In the PVP case, when packet size is 1518B, 10G nic could be the performance bottleneck, so we use 40G traffic genarator and 40G nic.
-* Also as vhost zero copy mbufs should be consumed as soon as possible, don't start send packets at vhost side before VM and virtio-pmd launched.
-
-Test flow
-=========
-
-TG --> NIC --> Vhost --> Virtio --> Vhost --> NIC --> TG
-
-Test Case 1: pvp split ring dequeue zero-copy test
-==================================================
-
-1. Bind one 40G port to igb_uio, then launch testpmd by below command::
-
- rm -rf vhost-net*
- ./testpmd -c 0xe -n 4 \
- --vdev 'eth_vhost0,iface=vhost-net,queues=1,dequeue-zero-copy=1' -- \
- -i --nb-cores=1 --txd=1024 --rxd=1024 --txfreet=992
- testpmd>set fwd mac
-
-2. Launch VM with mrg_rxbuf feature on, note that qemu_version need > qemu_2.10 for support adjusting parameter rx_queue_size::
-
- qemu-system-x86_64 -name vm1 \
- -cpu host -enable-kvm -m 4096 -object memory-backend-file,id=mem,size=4096M,mem-path=/mnt/huge,share=on -numa node,memdev=mem -mem-prealloc \
- -smp cores=5,sockets=1 -drive file=/home/osimg/ubuntu16.img \
- -monitor unix:/tmp/vm2_monitor.sock,server,nowait -net nic,macaddr=00:00:00:08:e8:aa,addr=1f \
- -net user,hostfwd=tcp:127.0.0.1:6002-:22 \
- -chardev socket,id=char0,path=./vhost-net \
- -netdev type=vhost-user,id=mynet1,chardev=char0,vhostforce \
- -device virtio-net-pci,mac=52:54:00:00:00:01,netdev=mynet1,mrg_rxbuf=on,rx_queue_size=1024,tx_queue_size=1024 \
- -vnc :10
-
-3. On VM, bind virtio net to igb_uio and run testpmd::
-
- ./dpdk-devbind.py --bind=igb_uio xx:xx.x
- ./testpmd -c 0x3 -n 4 -- -i --nb-cores=1 --txd=1024 --rxd=1024
- testpmd>set fwd mac
- testpmd>start
-
-4. Start testpmd at host side after VM and virtio-pmd launched::
-
- testpmd>start
-
-5. Send packets by packet generator with different packet sizes (64,128,256,512,1024,1518), show throughput with below command::
-
- testpmd>show port stats all
-
-6. Repeat the test with dequeue-zero-copy=0, compare the performance gains or degradation. For small packet, we may expect ~20% performance drop, but for big packet, we expect ~20% performance gains.
-

-DPDK Test suite.
-Test the performance of dequeue zero-copy.
-There are three topology test (PVP/VM2VM/VM2NIC) for this feature.
-And this testsuite implement the topology of PVP.
-Testsuite vm2vm_net_perf implement the topology VM2VM
-Testsuite gso implement the topology VM2NIC
-To run this suite, the qemu version should support packed ring.

I thought you want to say "has removed" , rather than "will remove"

Please remove it from test_plans/index.rst too.
Can't pass doc build:

-vhost dequeue zero-copy test plan
-=================================
-
-Description
-===========
-
-Vhost dequeue zero-copy is a performance optimization for vhost, the copy in the dequeue path is avoided in order to improve the performance. The test cases cover split ring and packed ring.
-Notice:
-
-* All packed ring case need special qemu version.
-* In the PVP case, when packet size is 1518B, 10G nic could be the performance bottleneck, so we use 40G traffic genarator and 40G nic.
-* Also as vhost zero copy mbufs should be consumed as soon as possible, don't start send packets at vhost side before VM and virtio-pmd launched.
-
-Test flow
-=========
-
-TG --> NIC --> Vhost --> Virtio --> Vhost --> NIC --> TG
-
-Test Case 1: pvp split ring dequeue zero-copy test
-==================================================
-
-1. Bind one 40G port to igb_uio, then launch testpmd by below command::
-
- rm -rf vhost-net*
- ./testpmd -c 0xe -n 4 \
- --vdev 'eth_vhost0,iface=vhost-net,queues=1,dequeue-zero-copy=1' -- \
- -i --nb-cores=1 --txd=1024 --rxd=1024 --txfreet=992
- testpmd>set fwd mac
-
-2. Launch VM with mrg_rxbuf feature on, note that qemu_version need > qemu_2.10 for support adjusting parameter rx_queue_size::
-
- qemu-system-x86_64 -name vm1 \
- -cpu host -enable-kvm -m 4096 -object memory-backend-file,id=mem,size=4096M,mem-path=/mnt/huge,share=on -numa node,memdev=mem -mem-prealloc \
- -smp cores=5,sockets=1 -drive file=/home/osimg/ubuntu16.img \
- -monitor unix:/tmp/vm2_monitor.sock,server,nowait -net nic,macaddr=00:00:00:08:e8:aa,addr=1f \
- -net user,hostfwd=tcp:127.0.0.1:6002-:22 \
- -chardev socket,id=char0,path=./vhost-net \
- -netdev type=vhost-user,id=mynet1,chardev=char0,vhostforce \
- -device virtio-net-pci,mac=52:54:00:00:00:01,netdev=mynet1,mrg_rxbuf=on,rx_queue_size=1024,tx_queue_size=1024 \
- -vnc :10
-
-3. On VM, bind virtio net to igb_uio and run testpmd::
-
- ./dpdk-devbind.py --bind=igb_uio xx:xx.x
- ./testpmd -c 0x3 -n 4 -- -i --nb-cores=1 --txd=1024 --rxd=1024
- testpmd>set fwd mac
- testpmd>start
-
-4. Start testpmd at host side after VM and virtio-pmd launched::
-
- testpmd>start
-
-5. Send packets by packet generator with different packet sizes (64,128,256,512,1024,1518), show throughput with below command::
-
- testpmd>show port stats all
-
-6. Repeat the test with dequeue-zero-copy=0, compare the performance gains or degradation. For small packet, we may expect ~20% performance drop, but for big packet, we expect ~20% performance gains.
-

-
- testpmd>show port stats all
-
-6. Relaunch testpmd at virtio side in VM for driver reloading::

-
-Test Case 9: pvp packed ring dequeue zero-copy test with ring size is not power of 2
-====================================================================================
-
-1. Bind one port to igb_uio, then launch vhost by below command::
-
- rm -rf vhost-net*
- ./x86_64-native-linuxapp-gcc/app/testpmd -n 4 -l 2-4 \
- --file-prefix=vhost --vdev 'net_vhost0,iface=vhost-net,queues=1,client=1,dequeue-zero-copy=1' \
- -- -i --nb-cores=1 --txd=1024 --rxd=1024 --txfreet=992
- testpmd>set fwd mac
- testpmd>start
-
-2. Launch virtio-user by below command::
-
- ./x86_64-native-linuxapp-gcc/app/testpmd -n 4 -l 5-6 \
- --no-pci --file-prefix=virtio \
- --vdev=net_virtio_user0,mac=00:01:02:03:04:05,path=./vhost-net,in_order=0,mrg_rxbuf=1,packed_vq=1,queue_size=1025,server=1 \
- -- -i --rx-offloads=0x10 --nb-cores=1 --txd=1025 --rxd=1025
- >set fwd mac
- >start
-
-3. Send packet with packet generator with different packet size,includes [64, 128, 256, 512, 1024, 1518], check the throughput with below command::
-
- testpmd>show port stats all
-
-4. Repeat the test with dequeue-zero-copy=0, compare the performance gains or degradation. For small packet, we may expect ~20% performance drop, but for big packet, we expect ~20% performance gains.
