Bug#1074441: linux-image-amd64: Please enable several CONFIG_ options required for IPU6/MIPI cameras

[Marten van Kerkwijk <mhvk@astro.utoronto.ca>]

Hi,

It would indeed be nice if the options for IPU6 support were enabled.
I tried compiling a new kernel using linux-source-6.10.  Starting with
/boot/config-6.10.3-amd64, I used make menuconfig to search for the
relevant configuration names and then set those to module.  Turned out
one needs to set just four:

CONFIG_VIDEO_OV2740=m
CONFIG_USB_LJCA=m
CONFIG_INTEL_MEI_VSC_HW=m
CONFIG_INTEL_MEI_VSC=m

The other ones listed above get set automatically.

On my lenovo x1 yoga gen 8, things are not quite stable: e.g., I have to
remove and reload the ov2740 module after boot for the camera to be
recognized.  The same is true when I use the fedora kernel provided at
https://copr.fedorainfracloud.org/coprs/jwrdegoede/ipu6-softisp/
Unlike with that kernel, though, I cannot yet use the camera in any way
with the new 6.10 one I built.

All the best,

Marten
