136. Eventdev Pipeline SW PMD Tests

136.1. Prerequisites

136.2. Test Case: Keep the packets order with default stage in single-flow and multi-flow

Description: the packets’ order which will pass through a same flow should be guaranteed.

  1. Run the sample with below command:

    # ./build/eventdev_pipeline --vdev event_sw0 -- -r2 -t4 -e8 -w F0 -s1 -n0 -c32 -W1000 -D
    
    Parameters:
    -r2, -t4, -e8: allocate cores to rx, tx and shedular
    -w: allocate cores to workers
    -s1: the sample only contain 1 stage
    -n0: the sample will run forever without a packets num limit
    
  2. Send traffic from ixia device with same 5 tuple(single-link) and with different 5-tuple(multi-flow)

  3. Observe the packets received by ixia device, ensure packets in each flow remain in order, but note that flows may be re-ordered compared to eachother.

136.3. Test Case: Keep the packets order with one ordered stage in single-flow and multi-flow

Description: the sample only guarantee that keep the packets order with only one stage.

  1. Run the sample with below command:

    # ./build/eventdev_pipeline --vdev event_sw0 -- -r2 -t4 -e8 -w F0 -s1 -n0 -c32 -W1000 -o -D
    
  2. Send traffic from ixia device with same 5 tuple(single-link) and with different 5-tuple(multi-flow)

  3. Observe the packets received by ixia device, check the packets order.

136.4. Test Case: Check load-balance behavior with default type in single-flow and multi-flow situations

Description: In multi-flow situation, sample should have a good load-blanced behavior; in single-flow, the load-balanced behavior is not guaranteed;

  1. Run the sample with below command:

    # ./build/eventdev_pipeline --vdev event_sw0 -- -r2 -t4 -e8 -w F0 -s1 -n0 -c32 -W1000 -D
    

2. Use traffic generator to send huge number of packets: In single-flow situation, traffic generator will send packets with the same 5-tuple which is used to calculate rss value; In multi-flow situation, traffice generator will send packets with different 5-tuple;

  1. Check the load-balance bahavior by the workload of every worker.

136.5. Test Case: Check load-balance behavior with order type stage in single-flow and multi-flow situations

Description: A good load-balanced behavior should be guaranteed in both single-flow and multi-flow situations.

  1. Run the sample with below command:

    # ./build/eventdev_pipeline --vdev event_sw0 -- -r2 -t4 -e8 -w F0 -s1 -n0 -c32 -W1000 -o -D
    

2. Use traffic generator to send huge number of packets: In single-flow situation, traffic generator will send packets with the same 5-tuple which is used to calculate rss value; In multi-flow situation, traffice generator will send packets with different 5-tuple;

  1. Check the load-balance bahavior by the workload of every worker.

136.6. Test Case: Check load-balance behavior with parallel type stage in single-flow and multi-flow situations

Description: A good load-balanced behavior should be guaranteed in both single-flow and multi-flow situations.

  1. Run the sample with below command:

    # ./build/eventdev_pipeline --vdev event_sw0 -- -r2 -t4 -e8 -w F0 -s1 -n0 -c32 -W1000 -p -D
    

2. Use traffic generator to send huge number of packets: In single-flow situation, traffic generator will send packets with the same 5-tuple which is used to calculate rss value; In multi-flow situation, traffic generator will send packets with different 5-tuple;

  1. Check the load-balance bahavior by the workload of every worker.

136.7. Test Case: Performance test for default type of stage

Description: Execute performance test with atomic type of stage in single-flow and multi-flow situation. We use 4 worker and 2 stage as the test background.

  1. Run the sample with below command:

    # ./build/eventdev_pipeline --vdev event_sw0 -- -r2 -t4 -e8 -w F0 -s2 -n0 -c32
    
  2. use traffic generator to send huge number of packets(with same 5-tuple and different 5-tuple)

  3. observe the speed of packets received.

136.8. Test Case: Performance test for parallel type of stage

Description: Execute performance test with parallel type of stage in single-flow and multi-flow situation. We use 4 worker and 2 stage as the test background.

  1. Run the sample with below command:

    # ./build/eventdev_pipeline --vdev event_sw0 -- -r2 -t4 -e8 -w F0 -s2 -n0 -c32 -p
    
  2. use traffic generator to send huge number of packets(with same 5-tuple and different 5-tuple)

  3. observe the speed of packets received.

136.9. Test Case: Performance test for ordered type of stage

Description: Execute performance test with ordered type of stage in single-flow and multi-flow situation. We use 4 worker and 2 stage as the test background.

  1. Run the sample with below command:

    # ./build/eventdev_pipeline --vdev event_sw0 -- -r2 -t4 -e8 -w F0 -s2 -n0 -c32 -o
    
  2. use traffic generator to send huge number of packets(with same 5-tuple and different 5-tuple)

  3. observe the speed of packets received.

136.10. Test Case: Basic forward test for all type of stage

Description: Execute basic forward test with all type of stage.

  1. Run the sample with below command:

    # ./build/eventdev_pipeline --vdev event_sw0 -- -r2 -t4 -e8 -w F0 -s1 -n0 -c32
    
  2. use traffic generator to send some packets and verify the sample could forward them normally
