CamHAL[ERR] Failed to find DevName for cameraId: 0, get video node: ov13b10 , devname: /dev/v4l-subdev1

[ChocolateLoverRaj]

I have an IPU6 camera and I installed drivers for it with these commands:

sudo dnf update \
  --enablerepo=updates-testing \
  --enablerepo=rpmfusion-free-updates-testing \
  --enablerepo=rpmfusion-nonfree-updates-testing \
  'kernel*' '*v4l2loopback' -y

sudo dnf install \
  --enablerepo=updates-testing \
  --enablerepo=rpmfusion-free-updates-testing \
  --enablerepo=rpmfusion-nonfree-updates-testing \
  akmod-intel-ipu6 -y

On firefox, the camera is just a black rectangle. When running sudo -E gst-launch-1.0 icamerasrc buffer-count=7 ! video/x-raw,format=NV12,width=1280,height=720 ! videoconvert ! ximagesink, I get this error:

CamHAL[ERR] Failed to find DevName for cameraId: 0, get video node: ov13b10 , devname: /dev/v4l-subdev1

Am I missing something? What should I do to get the camera to work? Is there something Intel needs to fix for it to work?

[brmarkus]

Can you provide a config file for your camera sensor (based on one of the existing files)?

[ChocolateLoverRaj]

I don't know where the file ov13b10.aiqb is located. How can I find it?

[brmarkus]

This is what you could provide - this is what the error log messages say, that "there is no aiqb file:ov13b10".

There are several config files provided, which could be used as a template - and adapted to your specific sensor I think:

You might want to have a deeper look into the CameraHAL repo.
(usually starting from this repo using this branch: "https://github.com/intel/icamerasrc/tree/icamerasrc_slim_api", pointing to "https://github.com/intel/ipu6-camera-hal/tree/iotg_ipu6")

[ChocolateLoverRaj]

I have a HI556 camera, which I see here: https://github.com/intel/ipu6-camera-hal/tree/iotg_ipu6/config/linux/ipu6ep.

[brmarkus]

Do you see some of the example pipelines under "https://github.com/intel/icamerasrc/tree/icamerasrc_slim_api#pipeline-examples" working?
Can you try to give your camera device-name via the attribute device-name according to the available camera-HAL example config-files (camera/sensor-config files)?

[ChocolateLoverRaj]

I tried all of the example pipelines and all of them result in an error. I don't know how to set the device-name attribute and I don't see any examples.

[brmarkus]

Under "https://github.com/intel/icamerasrc/tree/icamerasrc_slim_api#pipeline-examples" you can see example pipelines, where you can specify the device-name (in case the camera/sensor is not detected properly or is too exotic), e.g.:

Depending on the config files (you might want to look into the sample XML-config files for settings, parameters, naming, etc.), e.g.:

https://github.com/intel/ipu6-camera-hal/blob/iotg_ipu6/config/linux/ipu6ep/sensors/ov13b10-wf.xml

But there could easily HW-specifics depending on your camera, sensor, how it is connected (USB? Mipi-CSI?), virtual-ports being used, firmware flashed, etc.

[ChocolateLoverRaj]

The camera is a built-in webcam for Google Chromebook Redrix. It is connected with i2c I think because it is /sys/bus/i2c/devices/i2c-INT3537:00

[ChocolateLoverRaj]

also is this the right GitHub repo to create an issue?

[andaag]

I've run into this issue - but only after upgrading to kernel 6.5, in 6.4 it was working fine.

[brmarkus]

Do you use an USB based camera? Are certain kernel options (like CONFIG_MEDIA_USB_SUPPORT=y, CONFIG_USB_VIDEO_CLASS=y, CONFIG_USB_G_WEBCAM=y and CONFIG_MEDIA_CAMERA_SUPPORT=y) still enabled?

Do you use an IPU based camera? How have you installed the IPU drivers (e.g. IPU6)? Also e.g. libdrm-dev is required - see the section "https://github.com/intel/icamerasrc/tree/icamerasrc_slim_api#build-instructions" - so you might need to re-build/re-install IPU (ipu6, hal, bin) and icamerasrc again after upgrading the kernel.

[andaag]

I use a Dell XPS 9320 and the fedora rpmfusion testing packages. I have all these packages installed, and akmod should be recompiling the ipu6 driver when needed. I haven't rebuilt the rpm's for hal/bin/icamerasrc again though after kernel change, not sure how that'd be feasible to do with rpm's either? For that I guess we'd need to convert those to akmod or something like it aswell.

I do have the kernel module loaded:

Do you have documented how you got it working with the previous kernel, do you have records about which versions of IPU-module, IPU bin and hal and icamerasrc you had installed? Was it just working, or did you create and add a camera-sensor specific config file (like this issue is about)?

Would it be possible to downgrade the kernel again?

The dev-team would anyway need logs to analyze further to see if upgrading the kernel did update dependencies as well which introduced changes looking like a regression?

Just got a fix for this in another issue I'm also watching. After applying this intel/ipu6-drivers#22 (comment) fix manually everything works again!
