Can not use a Camera module 3 on custom kernel, Gentoo, of course.

Dmesg diff between Raspberry Pi OS and Gentoo is:

Does somebody know what I am missing from kernel config ?

Thank you!

What kernel are you using? Are you using the Raspberry Pi kernel sources at https://github.com/raspberrypi/linux.git ? The default for RPi 5 would be "make bcm2835_defconfig" in that tree. I personally use the config for the RPi 4 ("make bcm2709_defconfig") and use the same kernel on both RPi 4 and 5. I started with the RPi 4 config and modified it to add more features I wanted in my Gentoo install on RPi 4/5. Make sure you get the device trees (overlays directory) and the bcm2712-rpi-5-b.dtb in /boot.

Sorry, I haven't had time in the last days for this project.
Tested with boot folder, /lib/modules and firmware from Raspberry Pi OS, but there were errors:

Code: Select all

platform rp1_firmware: deferred probe pending: (reason unknown)
platform 1f00178000.pio: deferred probe pending: rp1-pio: failed to find RP1 firmware driver

Yes, the kernel is compiled from official Raspberry Pi Kernel sources. Will pursue your suggestion and start from a scratch config.
Thank you!

Have compiled kernel with bcm2712_defconfig and video devices are there:

No cameras available!

Still, no camera. Right now, the dmesg output between Gentoo and Raspberry Pi OS are, except timing, the same.
What else could be ?

You have

dtoverlay=imx708

in your config? It's worth checking the overlay exists too...

Tested with every variant: camera_auto_detect=1, dtoverlay=imx708 and nothing regarding camera in config.txt.

camera_auto_detect=1 is the default, so you have to you have to pair dtoverlay=imx708 with camera_auto_detect=0.
This is quite odd as cam3 is like over 2 years old, have you pulled any older pre-built kernels to check for a regression?

maybe not detection is the issue.

Thank you very much for your support. Will post camera-bug-report on github, finger crossed.

I wonder could it be permission issue?

Have you try to use strace on the command "libcamera-hello --list-cameras"

Code: Select all

strace -ff -o /tmp/libcamera-hello libcamera-hello --list-cameras

The idea here is to see if the libcamera-hello want to access something but because permission not allow therefor it just show nothing.

strace output is in /tmp/libcamera-hello.*

The issue was lack of pisp support on libcamera. I also compile for a Raspberry Pi 4, still in service, so I didn't think that this could be another "gpiod case". Support for Pi5 was missing.
Here is the issue on rpicam-apps, github.

Except libpisp, the ebuilds are (updated) from zugaina.org,
