Upgrade from Dizzy to Fido breaks video stream

[chrgrff1]

We've got a custom TVP5147 driver that worked under Dizzy. We recently upgraded to Fido, and I'm getting mxc_v4l_dqueue timeouts now.

I diffed the kernel drivers in drivers/media/platform/mxc/capture and it doesn't look like there were any API changes to the ADV7180 or OV5640 drivers between Dizzy and Fido, so I'd hoped our driver would just continue to work.

I've attached the kernel log from a simple "gst-launch-1.0 imxv4l2src ! imxv4l2sink" to demonstrate the timeouts. I'm hoping there's a known upgrade path for me to take or that someone can point me in the right direction to debug this.

Thank you!

I can actually boot the Fido file system with the Dizzy kernel and get working video; the Dizzy file system with the Fido kernel gives me the same errors as above. That kind of hints that it's not anything like gstreamer but is in the kernel.

I'll inspect the Fido kernel configuration and device tree in more detail.

[Yuri]

Hello,

Looks like You have to adapt the TVP5147 driver to new kernel 3.14.28.

Have a great day,
Yuri

Hi Yuri,

Thank you for the response, but I'm not really sure where to go with it.

Since the drivers for the ADV7180 (which I used as a template) didn't change from 3.10 to 3.14, are there any specific changes you're aware of that I should look at? I see that the v4l2-intdev files were moved to the local directory, it looks like there were some changes to the IPU driver to support using CSI0 and CSI1, but since there were no API changes to the supported camera drivers, I would expect mine to still work.

It looks like the problem might be that csi_enc_callback is not getting called; I can see that ipu_request_irq is being called (and succeeds) with IPU_IRQ_CSI0_OUT_EOF, and that the V4L2 ioctls (STREAMON, QBUF, DQBUF) are being called, but csi_enc_callback is never run.

edit: Additionally, I can see that the driver is locked on the the NTSC signal, pixel clock and pixel data lines are active, etc.
