TDA4VM: multi-camera streaming failed and get dma callback warning

HI Dennis,

Dennis Tseng said:

ds90ub962 and ds90ub953

Could you please confirm if you are using ub962 or ub960 deserializer? 

The logs says ub960. Are you using the same?

Have you tried streaming this camera individually without any other components such as mosaic or display, to ensure that camera streaming part works fine?

Regards,

Nikhil

Both of them are using the same driver ds90ub960, that why the log always show ub960.

I have tried streaming camera individually and it looks not too bad. and also using v4l2-ctl stream-map to ensure that cameras data source are fine.

Here's another issue I found, when I run v4l2-ctl command on each camera individually, it will stuck at third or fourth one.

root@rovy-4vm:~# v4l2-ctl -d /dev/video-tevs-cam3 --stream-mmap

But if I run 4 cameras with v4l2-ctl at the same time, the issue will not happen.

Hello,

The engineer assigned is out of office, please expect a couple of day delay.

Best,

Josue

Hi Dennis,

Could you try reducing the resolution to 1080p? Please see the encoder and decoder limitations here: 3.7. Multimedia Video Codec — Processor SDK Linux for J721e Documentation

Dennis Tseng said:

Here's another issue I found, when I run v4l2-ctl command on each camera individually, it will stuck at third or fourth one.

This is a known issue where we see the CSI2RX SHIM DMA context channel 0 accepts all handled data. Due to the driver implementation, all of the other sensors are still streaming so when one (or a subset) of cameras in a multi-camera system is streaming, DMA context 0 accepts frames from different virtual channels.

This issue is being addressed internally but for the time being, streaming from one or a subset of cameras in a multi-camera system is not supported.

Thank you,

Fabiana

Appreciate and fully respect you reply the info. We really look forward to get a resolution on it.

Okay, I will test it as soon as possible.

Fabiana Jaimes said:

Our case 720p is smaller than 1080p  that should be good.

Beside, I didn't using any encoder or decoder in the stream pipe, so my case do not have these limitation I think.

Hi Dennis,

Do you see this issue when removing a camera from the system and running a 7 camera pipeline?

Thank you,

Fabiana

Yes, it still happen.

Hi Dennis,

Thank you for confirming. I will be running a few tests on my end. Expect a response from me by next week.

Thanks,

Fabiana

Hi Dennis,

This issue has been fixed in the next SDK version release that will be available later this month. I advise you to switch to that version once it is released.

Thank you,

Fabiana

Hi Fabiana,

Do you mean that the issue regarding single camera streaming (or fewer than N camera streaming, where N is the total number of cameras in the system) in a multi-camera setup is fixed in SDK10.0?

If so that is GREAT.  But, and I know this is a big ask, is it possible to provide us with a link to the specific patch that fixes it?  Moving from SDK9.1 to SDK10.0 is a big step and we'd like to (ideally) be able to patch the kernel or drivers to fix it.

Thanks,

John

Hi John,

This may have been pushed back to 10.02. Please allow me some time to look into the current status and discuss with my team.

Thank you,

Fabiana

Hi Fabiana,

Thanks.  In absence of this, one thing that may help is to understand how to stream all cameras, while only processing a one or more of those cameras.

For example, if we have 4 cameras connected into a DS90UB962, currently TI supports only streaming all 4 cameras at the same time due to the limitation you mentioned above.  How can we stream from all 4 cameras, but only process the stream from a subset of them?  Ideally, using gstreamer?

One thing that we've messed around with is gst-interpipe, which is a RidgeRun plugin.  It seems to work well enough, but has some latency accumulation issues, so it isn't very usable.

John

Hi John,

Could you please create a new thread to discuss this topic? Could you elaborate on what solution you're looking for with any pipelines diagrams? Take a look at this single/multi input, multi inference example and let me know if you're looking to do something similar: https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-sk-tda4vm/09_02_00/exports/edgeai-docs/common/edgeai_dataflows.html#id4

Thank you,

Fabiana

Hi Fabiana,

Sure. Will do. Sorry to derail this particular thread.

Can you please let us know what fixes are implemented in SDK10.0 for the CSI DMA issue, and if we can get specific patches identified so that we can see if we can backport to SDK9.1?

Thanks,

John

Hi Fabiana,

It will be helpful if you can provide the fixed patch for me to use on current SDK.
I think I don't want only fixed this and increase loading to update SDK version.

Hopefully a minimal change can fix it.

Thanks,

Dennis
