Original question:

SK-TDA4VM: Gstreamer object detection latency issues

SK-TDA4VM: TDA4VM restart issue, after changing display to weston and using glimagesink

Gokul Soman

Part Number: SK-TDA4VM
Other Parts Discussed in Thread: TDA4VM

As I have not been able to achieve high FPS (greater than 30 FPS) using kmssink, I had changed the display element in gstreamer to glimagesink. This was based on a previous query I had raised (Link).

Although the achievable FPS is higher, there is a restart issue that is occurring as of now. I am not able to diagnose the error as the restart of the board happens fairly quickly. The terminal output is as shown

The final line is the error that is displayed.

Kindly help resolve this issue.

I would also like to get more information on these 2 topics

1. How to optimize the targeting of DSPs so as to avoid bottlenecks, or overloading of any DSP

2. The significance of the parameter out-pool-size in tiovxdlpreproc gstreamer element, and how to determine the best value for this parameter

Thanks,

    Hi Gokul,

    As for the initial issue, could you try running the attached script before running the pipeline:

    tda4vm_gpu_fix.sh

    As for 1.), I would recommend using the perfstat tool to see which cores are being overloaded (at 100% usage): https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-sk-tda4vm/08_04_00/exports/docs/performance_visualizer.html#generating-performance-logs and move the plugins between the cores such that the DSPs are not overloaded.

    2.) I will need to check on this one, but our examples usually specify out-pool-size=4: https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-sk-tda4vm/08_04_00/exports/docs/data_flows.html

    Regards,

    Takuma

    Hi Gokul,

    Just got some more clarifications on 2). The out-pool-size should depend on where the bottleneck is, that is, if there is a GStreamer plugin that often waits for a buffer to be free due to all the buffers in the buffer pool being used, increasing the out-pool-size should improve the performance.

    Hi,

    I have tried reducing the frame rate below 20 to run this. This happens even when the DSPs are not overloaded (20 %).

    Specifically, the error that keeps on coming is this

    (4253) PVR:(Error): ScheduleTA: Skipping render from different gc/thread! [ :5864 ]

    Can you explain when this error pops up in the TDA4VM platform? And also any method to solve this?

    ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

    As of now, the current pipeline is such

    v4l2src device=/dev/video2 io-mode=2 ! image/jpeg, width=640, height=480 ! jpegdec ! tiovxdlcolorconvert target=1 ! video/x-raw, format=NV12 ! tiovxmultiscaler name=split_01
    split_01. ! queue max-size-buffers=2 leaky=2 ! video/x-raw, width=640, height=480 ! videoscale ! video/x-raw, width=640, height=640 ! tiovxdlpreproc data-type=3 target=0 channel-order=0 tensor-format=bgr out-pool-size=4 ! application/x-tensor-tiovx ! appsink name=pre_0 max-buffers=1 drop=true
    split_01. ! queue ! video/x-raw, width=640, height=480 ! tiovxdlcolorconvert target=1 out-pool-size=4 ! video/x-raw, format=RGB ! appsink name=sen_0 max-buffers=2 drop=true

    As a further input, I am using threading in my code --> different appsink pipelines outputs are taken in parallel threads in the python code. Could this be causing issue?

    Thanks,

    Gokul

    Hi Gokul,

    The PVR error is GPU related. Could you try running the script tda4vm_gpu_fix.sh that I sent two responses back?

    Hi,

    Based on this input

    1. I first changed the display to wayland

    2. Ran the gpu fix script

    3. Ran the rest of the code.

    The board does not restart, but becomes unusable, after which I have to manually restart (by pressing the reset button). The terminal also stops working.

    A section of the logs that is show in minicom is as such

    Hence the code does not work at all If I run the gpu_fix script, but works to some extent if I run without it.

    Thanks for your constant support.

    Hi Gokul,

    Could you also post the output from the gpu_fix script? I would like to make sure the registers are actually getting updated, since on my setup this script was able to fix the initial PVR issue.

    Also, please note that the gpu_fix script needs to run after each reboot, since the register changes are not persistent over reboot.

    Regards,

    Hi,

    Attaching the output of the gpu_fix script here

    -------------------------------------------

    I tried some more things to locate the error. All of the output is taken through minicom.

    If I run the gpu fix script first, and then initialize weston, I'm getting the error as such.

    Hence, I am initializing weston first and then running the gpu fix script. Which does not cause any errors.

    After this, even if I try a simple pipeline, as such

    gst-launch-1.0 v4l2src device=/dev/video2 ! image/jpeg, width=640, height=480, framerate=60/1 ! jpegdec ! glimagesink

    , I am getting errors as such

    If I only initialize the weston, and skip the gpu fix script, atleast the pipeline mentioned above will run. Although the PVR error will be displayed in this case

    The main problem for me in executing my script is the restart issue. Would like any points that may help regarding this.

    Thanks and Regards,

    Hi Gokul,

    It is probably due to the version of GPU driver. If you have the bandwidth, can you see if you can follow this guide using PSDK 8.4 instead of 8.2 to update GPU PVR driver to 1.15: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1094811/faq-tda4vm-how-do-i-update-the-gpu-driver-to-a-newer-version

    If not, I will need around 1 to 2 days to generate/test the binaries that would work with the Edge AI SDK 8.4 image.

    Regards,

    Takuma

    Hi,

    I tried to do this part. But in the end, the image I built does not have many of the required functions that were available in the balena-etcher image.

    This includes

    - onnxruntime (import error)

    - tiovx gstreamer elements

    If these are also present, then I maybe able to port the code into this.

    ---------------------------------------------

    Were you asking me to flash the 8.4 balena-etcher image first to sd card, and then use the generated .ko file (step 8) in that image?

    Regards,

    Gokul

    Yes, exactly. Could you try copying in the following into the rootfs partition of the SD card:

    8_4_sdk_new_gpu_driver.zip

    These are the latest GPU drivers available, compiled for the latest 8.4 SDK. I have tested this combination out and so far have not seen the PVR error messages.

    Hi,

    Tried the method you told. Still facing errors --> no restart, but inference is not happening

    - In minicom, the error is as such

    Hi Gokul,

    If this is on the 8.2 SDK version, could you try running the following script:

    sk_pmic_reboot_fix.sh

    We had a bug that was fixed in 8.4 SDK version where the board will reboot itself in certain circumstances.

    As for the logs:

    For the first set of logs shared with the tidss (TI display sub system) issues, it looks like a display/GPU issue. It may be the drivers I shared were not happy with the system - I compiled the binaries for 8.4, but if you are on 8.2, I can recompile and test them on that version as well before sharing.

    As for the second set of logs, they are related to TIDL (TI Deep Learning) node, which is called by the runtimes like ONNX or TFLite runtimes. These seem separate from the issues that we were having, since the TIDL error messages should be unrelated to GPU or display. These error messages may come up if the application shuts itself off in a weird state, and usually fixed by a reboot of the board. Do these error messages come up after rebooting?

    Lastly, thank you for your patience with this debug. We will continue to debug on our end as well, and hopefully we can work out a fix together.

    Regards,

    Takuma

    The two sets of logs are coming together. I just kept two terminals open, one in minicom, and one in SSH. I was taking the outputs that were coming in each terminal in this case. I ran the code on the 8.4 version of TI SDK, so dont really know what happened there..

    It would be great if you can compile the binaries for 8.2. In the 8.4 one, I am facing the previous error logs, constant glitches on screen, and no bounding boxes being displayed. I will test it on that as well from my side.

    I will try the script provided by you as well, and update you if any issues are obtained on that side.

    Regards

    Hi Gokul,

    I posted on our previous thread the solution to the original issue where kmssink was capping at 30 FPS: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1159489/sk-tda4vm-gstreamer-object-detection-latency-issues

    We will continue to look into the issue with glimagesink/GPU, but let us know if the changes to the GStreamer pipeline I posted in our previous thread will unblock you.

    Regards,

    Takuma

    Hi Gokul,

    I have not heard back in a while, but were you able to work around the issue being faced? Or is this still an open issue?

    Regards,

    Takuma
