132. vhost-user interrupt mode test plan

132.1. Description

Vhost-user interrupt need test with l3fwd-power sample, small packets send from virtio-user to vhost side, check vhost-user cores can be wakeup,and vhost-user cores should be back to sleep after stop sending packets from virtio side.

132.2. Test flow

Virtio-user –> Vhost-user

132.3. Test Case1: Wake up split ring vhost-user core with l3fwd-power sample

  1. Launch virtio-user with server mode:

    ./testpmd -l 7-8 -n 4 --no-pci --file-prefix=virtio \
    --vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/sock0,server=1,queues=1 -- -i
    
  2. Build l3fwd-power sample and launch l3fwd-power with a virtual vhost device:

    ./l3fwd-power -l 0-3 -n 4 --no-pci \
    --vdev 'eth_vhost0,iface=/tmp/sock0,queues=1,client=1' -- -p 0x1 --parse-ptype 1 --config "(0,0,2)"
    
  3. Send packet by testpmd, check vhost-user core will keep wakeup status:

    testpmd>set fwd txonly
    testpmd>start
    
  4. Stop and restart testpmd again, check vhost-user core will sleep and wakeup again.

132.4. Test Case2: Wake up split ring vhost-user cores with l3fwd-power sample when multi queues are enabled

  1. Launch virtio-user with server mode:

    ./testpmd -l 1-5 -n 4 --no-pci --file-prefix=virtio \
    --vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/sock0,server=1,queues=4 -- -i --rxq=4 --txq=4 --rss-ip
    
  2. Build l3fwd-power sample and launch l3fwd-power with a virtual vhost device:

    ./l3fwd-power -l 9-12 -n 4 --no-pci --log-level=9 \
    --vdev 'eth_vhost0,iface=/tmp/sock0,queues=4,client=1' -- -p 0x1 --parse-ptype 1 \
    --config "(0,0,9),(0,1,10),(0,2,11),(0,3,12)"
    
  3. Send packet by testpmd, check vhost-user multi-cores will keep wakeup status:

    testpmd>set fwd txonly
    testpmd>start
    
  4. Stop and restart testpmd again, check vhost-user cores will sleep and wakeup again.

132.5. Test Case3: Wake up packed ring vhost-user core with l3fwd-power sample

  1. Launch virtio-user with server mode:

    ./testpmd -l 7-8 -n 4 --no-pci --file-prefix=virtio \
    --vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/sock0,server=1,queues=1,packed_vq=1 -- -i
    
  2. Build l3fwd-power sample and launch l3fwd-power with a virtual vhost device:

    ./l3fwd-power -l 0-3 -n 4 --no-pci \
    --vdev 'eth_vhost0,iface=/tmp/sock0,queues=1,client=1' -- -p 0x1 --parse-ptype 1 --config "(0,0,2)"
    
  3. Send packet by testpmd, check vhost-user core will keep wakeup status:

    testpmd>set fwd txonly
    testpmd>start
    
  4. Stop and restart testpmd again, check vhost-user core will sleep and wakeup again.

132.6. Test Case4: Wake up packed ring vhost-user cores with l3fwd-power sample when multi queues are enabled

  1. Launch virtio-user with server mode:

    ./testpmd -l 1-5 -n 4 --no-pci --file-prefix=virtio \
    --vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/sock0,server=1,queues=4,packed_vq=1,mrg_rxbuf=0 -- -i --rxq=4 --txq=4 --rss-ip
    
  2. Build l3fwd-power sample and launch l3fwd-power with a virtual vhost device:

    ./l3fwd-power -l 9-12 -n 4 --no-pci --log-level=9 \
    --vdev 'eth_vhost0,iface=/tmp/sock0,queues=4,client=1' -- -p 0x1 --parse-ptype 1 \
    --config "(0,0,9),(0,1,10),(0,2,11),(0,3,12)"
    
  3. Send packet by testpmd, check vhost-user multi-cores will keep wakeup status:

    testpmd>set fwd txonly
    testpmd>start
    
  4. Stop and restart testpmd again, check vhost-user cores will sleep and wakeup again.

132.7. Test Case5: Wake up split ring vhost-user cores with l3fwd-power sample when multi queues and cbdma are enabled

  1. Launch virtio-user with server mode:

    ./testpmd -l 1-5 -n 4 --no-pci --file-prefix=virtio \
    --vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/sock0,server=1,queues=4 -- -i --rxq=4 --txq=4 --rss-ip
    
  2. Bind 4 cbdma ports to igb_uio driver, then launch l3fwd-power with a virtual vhost device:

    ./l3fwd-power -l 9-12 -n 4 --log-level=9 \
    --vdev 'eth_vhost0,iface=/tmp/sock0,queues=4,client=1,dmas=[txq0@80:04.0;txq1@80:04.1;txq2@80:04.2;txq3@80:04.3]' -- -p 0x1 --parse-ptype 1 \
    --config "(0,0,9),(0,1,10),(0,2,11),(0,3,12)"
    
  3. Send packet by testpmd, check vhost-user multi-cores will keep wakeup status:

    testpmd>set fwd txonly
    testpmd>start
    
  4. Stop and restart testpmd again, check vhost-user cores will sleep and wakeup again.
