205. CryptoDev virtio unit Tests

205.1. Description

This document provides the plan for testing Cryptodev virtio API via Cryptodev unit tests. Unit tests include supported Hardware and Software PMD(polling mode device) and supported algorithms.

This test suite will run all cryptodev virtio related unit test cases. Alternatively, you could execute the unit tests manually by app/test DPDK application.

205.2. Unit Test List

  • cryptodev_virtio_autotest

205.3. Prerequisites

qemu version >= 2.12 and enable vhost-user-crypto:

./configure --target-list=x86_64-softmmu --enable-vhost-crypto --prefix=/root/qemu-2.12 && make && make install

the bin is in /root/qemu-2.12 folder, which is your specified

205.4. Test Case Setup

VM
HOST

In Host:

# Enable config item in dpdk:

enable CONFIG_RTE_LIBRTE_VHOST in config/common_base

# Build DPDK and app vhost_crypto

# Run the dpdk vhost sample:

./examples/vhost_crypto/build/vhost-crypto --file-prefix="vhost_crypto_1"
    [EAL options]
    [Cryptodev PMD]
    -- --cdev-queue-id 0
    --socket-file THE PATH OF SOCKET FILE

# bind vf or pf with driver vfio-pci:

usertools/dpdk-devbind.py --bind=vfio-pci 0000:60:00.0 0000:60:00.1

# Start VM by the qemu:

taskset -c 11,12,13,14 /root/qemu-2.12/bin/qemu-system-x86_64  -name vm0
    -enable-kvm -pidfile /tmp/.vm0.pid
    -cpu host -smp 4
    -m 5120 -object memory-backend-file,id=mem,size=5120M,mem-path=/mnt/huge,share=on -numa node,memdev=mem -mem-prealloc
    -net nic,vlan=0,macaddr=00:00:00:18:38:11,model=e1000,addr=1f -net user,vlan=0,hostfwd=tcp:10.67.111.126:6000-:22
    -device virtio-serial
    -device virtserialport,chardev=vm0_qga0,name=org.qemu.guest_agent.0
    -daemonize -monitor unix:/tmp/vm0_monitor.sock,server,nowait
    -vnc :1
    -chardev socket,path=/tmp/vm0_crypto0.sock,id=vm0_crypto0 -object cryptodev-vhost-user,id=cryptodev0,chardev=vm0_crypto0 -device virtio-crypto-pci,id=crypto0,cryptodev=cryptodev0
    -chardev socket,path=/tmp/vm0_crypto1.sock,id=vm0_crypto1 -object cryptodev-vhost-user,id=cryptodev1,chardev=vm0_crypto1 -device virtio-crypto-pci,id=crypto1,cryptodev=cryptodev1
    -drive file=/root/VMs/virtio_crypto_test_710_1.img
    -device vfio-pci,host=0000:60:00.0,id=pt_0
    -device vfio-pci,host=0000:60:00.1,id=pt_1

In VM:

# set virtio device:

modprobe uio_pci_generic
echo -n 0000:00:04.0 > /sys/bus/pci/drivers/virtio-pci/unbind
echo -n 0000:00:05.0 > /sys/bus/pci/drivers/virtio-pci/unbind
echo "1af4 1054" > /sys/bus/pci/drivers/uio_pci_generic/new_id

# Manually verify the app/test by this command, as example, in your build folder:

./app/test -c 1 -n 1
RTE>> cryptodev_virtio_autotest

Expected all tests could pass in testing.
