Testing

The tests will be performed with the camera hardware by another team so these are not available in Ghaf side. The software side tests include installation of v4l-tools to check the video devices of corresponding cameras.

1. Execute lsmod |grep avt_csi2 to see
   avt_csi2 106496 0
   and lsmod |grep tc358743 to see
   tc358743 49152 1
2. Check if /dev/video0 (Toshiba) and /dev/video1 (Alvium) and /dev/media0 video4linux interface devices exist with
   ls -la /dev/video0 /dev/video1 /dev/media0
3. install v4l-tools with
   nix-shell -p v4l-utils
4. Execute `v4l-ctl --list-devices' in the nix-shell to see the below result.

NVIDIA Tegra Video Input Device (platformtegra-camrtc-ca):
               /dev/media0
ALVIUM 1800 C-158m 9-3c (platformtegra-capture-vi:0):
               /dev/video1
tc358743 10-000f (platformtegra-capture-vi:2):
               /dev/video0

5. Execute below commands to get more detailed information about resolution colorspace and formats:

v4l2-ctl -d /dev/video0 --list-formats-ext
v4l2-ctl -d /dev/video0 --list-ctrls-menus
v4l2-ctl --device /dev/video0 --stream-mmap
v4l2-ctl -d /dev/video1 --list-formats-ext
v4l2-ctl -d /dev/video1 --list-ctrls-menus
v4l2-ctl --device /dev/video1 --stream-mmap

And the --stream-mmap will show the data input from the capture device.

6. install vlc with
   nix-shell -p vlc

A new issue is detected as my camera modules are built with 6.1.28 build your own kernel version of nvidia instead of the 5.10 of jetpack-nixos. I'll try to figure out where it overrides my settings.

Funny things happen in checks side. I've built this PR with AGX and NX both aarch64 and cross compile X86_64 and had no error while the checks report error.
