3.5.2.4.5. Run the Reference Example Application

  1. After the reference application is built, run it:

    $ ./build/mcdma-test -- -h

  2. This command will display the available options in the application as shown in the image below:
  3. Do a PIO test to check if the setup is correct. If successful, the application will show a Pass status.

    [root@BAPVENC011T perfq]# ./build/mcdma-test -- -b 0000:01:00.0 -o

    Here -b should be provided with the correct BDF in the system.

  4. The DPDK driver can be used with the AVST/AXIST Packet Generate/Check design example to test the packet generator and checker design.

    The following diagram shows the testing strategy.

    Configuration in examples/mcdma-test/perfq/perfq_app.h

    In the case of static channel mapping, modify the following parameters: 
    • /* PF count starts from 1 */
#define IFC_QDMA_CUR_PF <pf number>
• /* VF count starts from 1. Zero implies PF was used instead of VF */
#define IFC_QDMA_CUR_VF <vf number>
• /* Number of PFs */
#define IFC_QDMA_PFS <number of PFs>
/* Channels available per PF */
#define IFC_QDMA_PER_PF_CHNLS <number of channels per PF>
• /* Channels available per VF */
#define IFC_QDMA_PER_VF_CHNLS <number of channels per VF>
• /* Number of VFs per PF */
#define IFC_QDMA_PER_PF_VFS <number of VFs per PF>

    perfq_app command line parameters:

    Command: 
    $ ./build/mcdma-test -m 8192 --file-prefix=pf0 --\
 -b 0000:01:00.0 -p 32768 -d 2 -c 1 -a 2 -l 5 -z -n
    Configuration:
    1. 1 channel (-c 1)
    2. Packet generator bidirectional (-z)
    3. Payload length of 32,768 bytes in each descriptor (-p 32768)
    4. Transfer the data every 5 seconds (-l 5)
    5. Dump the progress log every second (-d 2)
    6. Configure the number of channels in ED (-n)
    7. Number of threads to be used for DMA purpose. (-a 2)
    Note: This hardware test was run with the Stratix® 10 GX H-tile PCIe Gen3 x16 configuration.

  5. The DPDK driver can also be used with the AVST/AXIST Device-side Packet Loopback design example to test loopback.

    The following diagram shows the testing strategy.

    Command: $ ./build/mcdma-test -m 8192 --file-prefix=pf0 -l 0-15 -- -b 0000:01:00.0 -p 32768 -d 2 -c 1 -a 2 -l 5 -i

    Configuration:
    1. 1 channel (-c 1)
    2. Packet generator bidirectional (-i)
    3. Payload length of 64 bytes in each descriptor (-p 32768)
    4. Transfer the data every 5 seconds (-l 5)
    5. Dump the progress log every second (-d 2)
    Note: This hardware test was run with the Stratix® 10 GX H-tile PCIe Gen3 x16 configuration.
