TDA4VM: v4l2 capture video error when using pcie ep at the same time

Hi,

Could you please provide detailed steps what you are following?

We could review this and try to reproduce the same at our end.

Regards,
Nikhil

steps:

1: connect the pcie1(j22)  to  host PC(x86+ubuntu18.04).

2: config the pcie1 of  sk-evm run as pcie endpoint just as the the instruction processor-sdk-linux-docs/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/PCIe/PCIe_End_Point.html

3: Run  pcitest.sh on  PC  side to send "read" command  always, (it is easily do to change the script to support it) 

4：run yavta on board to capture vide ,command like  "yavta /dev/video2 -c10 -n4 -s3856x2177 -fUYVY -Ftest_video.raw ", of course,we changed the v4l2 driver to support my sensor which support 3856X2177@30hz ,. You can capture used default sensor imx219 image too.  just like command "yavta /dev/video2 -c1 -n4 -s1920x1080 -fSRGGB10 -Ftest_video.raw"

5: used yuv tool just like 7yuv to view the video file test_vide.raw. you will find this issue.

Hi,

Can the pcitest.sh being run on the pc side be shared?

Apart from this can you clarify the following things for me:

• How frequently are you reading the data from RC side?
• How is it being ensured that the raw video data is being read over PCIe? I would assume that the pcie-epf has to know from where to read the data. Have you configured the corresponding BARs?
• There might be some read before write type of thing also going on for the raw data. Have you made any changes to ensure that this doesn't happen?

thanks Tanmay!

• How frequently are you reading the data from RC side?

          I read the data always ,the script is below.

• How is it being ensured that the raw video data is being read over PCIe? I would assume that the pcie-epf has to know from where to read the data. Have you configured the corresponding BARs?

        I have debuged with uvc camera(VGA)  or a fixed data to test pcie driver developed myself, It work ok.    I didin't edit the bar config of the test example. 

• There might be some read before write type of thing also going on for the raw data. Have you made any changes to ensure that this doesn't happen?

        I have saved the raw data to a file  by tool yavta and check it was ok.it seemed myself v4l2 driver works.

Hi,

Please let me know if my understanding is correct here regarding the issue.

Could you confirm if the 3rd usecase is OK or NOT OK?

Regards,

Nikhil

thanks Tanmay!

    Yes,You summarized it very well. it is ok for 3 too.    It was ok when we send some fixed image  by PCIE.

    I can supplement an idea that I can use a low resolution such as 640X480 (RGB format) from a UVC camera for real-time capture and PCIe transmission,It was work too.

hi Nikhil,can you have some new idea about this issue? 

I have checked dma channels ,the mipi-csi driver  used dma applied channel from 1 to 35  at fist (ti_csi2rx_init_dma()) but only used 1, The pcie applied dma channel 36 and used it, no  found  dma channel conflict .

Hi,

duke zuo said:

Could you do the same experiment with a lower resolution input data that uses csi-rx? (As UVC does not use csi-rx)

Could you also enable the trace logs or get timestamps from the csi-rx driver and the pcie. As this could be seen if the real time contraints are not met (i.e., if pcie is slow and csi-rx is fast, there are chances that the frames are dropped or corrupted)

Could you profile both to confirm if this is happening in your case?

Meanwhile could you share your kernal (boot) logs? Wanted to check if there are any resource errors here.

Regards,

Nikhil

thanks Nikhil!  I will try to  if we can used vga fromat by  imx219.  the kernel long  is below:

hi Nikhil:

    I have got tested result  with imx219 here:

1: VGA and no pcie transmit,  video ok

2: VGA and  pcie , video ok

3: 1080p and no pcie ,video ok

4: 1080p and pcie , video not ok

what do you think about it?

  Picture like this from sensor imx219 

hi Nikhil:

   I have test with uvc camera ,which support 4K format(3264X2448  , YUYV4:2:2), and find it works,I doubted something wrong with mipi-csi driver.what do you think about it?

Hi,

Here, I'm suspecting that the real time constraint of the csi-rx to maintain the FPS is being challenged here by the transmit rate of the pcie.

In order to check this, Could you provide me below two information?

duke zuo said:

4: 1080p and pcie , video not ok

1. Could you reduce the FPS of imx319 in the above case? I believe you are currently transmitting at 30 FPS right? If yes, could you reduce it further using v4l2 set commands?

2. Could you profile the transmit rate of one frame of the pcie when using imx319?

Regards,

Nikhil

I have found some driver log : "Failed to drain DMA. Next frame might be bogus"  if we run  pcie at the same time. and no pcie no this log. Is it helpful to resolve  the issue?

thank Nikhil

1. Could you reduce the FPS of imx319 in the above case? I believe you are currently transmitting at 30 FPS right? If yes, could you reduce it further using v4l2 set commands?

Yes, you are right, we used 30fps to test while i uvc used 2fps for 4k.   I will try reduce fps to test again.

2. Could you profile the transmit rate of one frame of the pcie when using imx319?

We checked  the pcie write rate is about 1.5G Byte/s  with PCIE3.0 , 2 lane here.

"Could you also enable the trace logs or get timestamps from the csi-rx driver and the pcie. As this could be seen if the real time contraints are not met (i.e., if pcie is slow and csi-rx is fast, there are chances that the frames are dropped or corrupted)

Could you profile both to confirm if this is happening in your case?"

Sorry, I have  missed this advice, I am testing video capturing  and PCIe separately now.  It seem the pcie speed is more fast than mipi-csi speed now. 

Hi,

duke zuo said:

Failed to drain DMA. Next frame might be bogus

This usually comes when there are frame drops.

We could first confirm if this is the case by reducing the fps.

Post that, I think we could either try increasing the number of buffers provided to csi-rx. I think, currently it is 4 (may be we could try increasing it to 6 and test this)

Regards,

Nikhil

hi, Nikhi,

        We have test with fps 15 and video format is 3840*2160, It work!  the video i saved in device or stored in pc views ok now! thank your advice!  

Hi,

Please let me know if this satisfies your usecase? Or is there a target FPS you are looking for?

Regards,

Nikhil

No,We  need 2 ways raw16 videos which must supported 3586X2177@30 hz and transmited video data  to host PC   by pcie In our really  project. This image sensor is not support 15 fps, so we have to switch another image sensor to debug tomorrow.

      By the way, When we runed pcie test program, We found offset of timestamp for v4l2 videobuf  were  over 33mm(30hz) when we used  3840*2160@30hz from our image sensor,  these are over 70ms often and sometime they  even reached 80ms, Other if we reduce fps to 15 hz, these were almost  66ms(15). 

Are there  some conflicts about DMA resource? what do you think about it? Thanks.

Hi,

I'm suspecting that the application might not be returning the buffers on time back to csi.

Could you try increasing the number of buffers and check again for 30fps?

Regards,

Nikhil

We increased the buffers number when used v4l2  VIDIOC_REQBUFS command and get the same result. 

By the way, If I reduce pcie fragment size from 1M to 128k and it caused  the pcie write rate decreased  much and  get v4l2  video frame ok with  format 3840*2160@30hz, So I have to discard video frame when used pcie writed to PC host.It is not met our project usecase. I think it will be better for  mipi-csi if pcie used dma resoure little.  but if we will capture 2 way videos by 2 mipi-csi interface with format 3840*2160@30hz, It need much DMA  resource too. how can i resolve it?

Hi ,Nikhil,   nice to receive your response,  From this  designed referent, It seem  it can receive 16M pixs@30 fps from 2 mipi-csi, it met our usecase  2X 8M@30 fps, It  used ISP at the same time and it need dma too. so it seem  UDMA bandwidth is enough. What do you think abou it?

By the way, I found some odd code in sdk source about pcie test file (linux-5.10.120+gitAUTOINC+95b90aa828-g95b90aa828/drivers/pci/endpoint/functions/pci-epf-test.c)

/*
* wait 1ms inorder for the write to complete. Without this delay L3
* error in observed in the host system.
*/
usleep_range(1000, 2000);

I have tested it can been redueced to 300us once sent a pcie packet (128K) and pc received ok(if it is less 300us, Host pc often lost packet), but for so much frame size 16M, it will cause  delay so much  (3588X2177X2/128/1024 x300=35ms) for one frame.  I want to know can we resolve the delay issue here? 

Hi Duke,

May I know how are you directing the output of csi to the pcie test? Are there any modifications made? 

As this is not a usecase that we have tested, it would be great if you could share your source code so that the internal experts could review the same regarding the buffer handling and pcie transactions.

Regards,

Nikhil

Hi Nikhil,

    I can shre you my drive and test code about  deivce and pc host side,  please tell me your email. thanks!   

We have change the fragment size to 165k and now it can capture one mipi video and pcie transmit ok.

Hi Duke,

Does this resolve your issue?

Regards,

Nikhil

haha,We need to communicate well with our customer for one mipi ,one pcie .
