Original question:

DRA80XMEVM: How to capture TIOVX kernel performance report

TDA4VM: Quarries regarding C7x DSP

Part Number: TDA4VM

Hello,
We are using TI provided pre-built 07.03.00.05 rootfs image for the DSP tests and have the following queries

1. TI OpenVX performance app produces empty HTML report. We followed the steps mentioned in the TIOVX User guide and got empty report. Can you let us know as to how the published results were generated for this BSP release?

2. We have developed DSP tests based on OpenVX kernels and would like to run them on C7X as well. Is there a plan to support these OpenVX kernels for C7X as well?
Regards,
 Pallab

    Hello Pallab,

    Answers to your questions below:

    1. I will take a look and try to replicate this issue on my end.

    2. We are planning on enabling the standard OpenVX kernels on C7x in the 8.2 SDK release.  However, we do not have plans to fully optimize these kernels for the C7x, they will only be recompiled for C7x from C66x.

    Regards,

    Hello Pallab,

    I double checked this on my end and was able to successfully generate this file.  Could you please try removing the /opt/vision_apps/test_data/output directory, then re-creating this directory?  Please then run "./vx_app_conformance.out --filter=tiovxPerf*" and let me know if the html report was successfully generated at /opt/vision_apps/test_data/output/tiovx_performance.html.

    Regards,

    Lucas

    Hi Lucas,

         We tried to run conformance test as per steps mentioned in your last comment but still the generated html file is empty.

    Hello Pallab,

    To clarify, is the file 0 bytes or does it have the header data but no performance data?

    Hi Lucas,

          That files contains  not even header also. Everytime we  run conformance test that file get created without any data(no header and performance data).

    Hello Pallab,

    I am not sure why this is the case.  We have not been able to replicate this on our end.

    As an alternative, you can update this to instead print to the console instead of writing to this file.  In order to do so, you can update the function PrintPerf in tiovx/conformance/test_tiovx/test_perf.c to simply print the values and test name rather than print it to file.
