Quartz64 | CONFIG_CAN_GS_USB is not set

[clee]

Required Information

• DietPi version | 8.12.1-master
• Distro version | bullseye
• Kernel version | Linux quartz64 6.1.0-rc1 #1 SMP PREEMPT Wed Nov 9 01:08:14 UTC 2022 aarch64 GNU/Linux
• SBC model | Pine64 Quartz64B (aarch64)
• Power supply used | 5V 3A DFRobot
• SD card used | SanDisk ultra

Steps to reproduce

1. Plug in a USB CAN adapter

Expected behaviour

• The gs_usb kernel module should load
• I should see a can0 network device when I run ip link list

Actual behaviour

• There is no gs_usb kernel module, and zgrep GS_USB /proc/config.gz reports # CONFIG_CAN_GS_USB is not set

hmm we don't do any kernel development. Probably an upstream issue? What do you think @MichaIng

[clee]

I think this is more of a kernel configuration issue; the module exists, it's just not being built/included here.

Another limitations of Peter Geis' Quartz64 kernel. WireGuard and some BPF related modules, required for container engines, are missing as well. Since he does not react to related merge requests, I guess we either need to compile the kernel ourselves, or use e.g. Debian's. Armbian does not (yet) support it.

FYI: #6151

The new set of images has this module available: https://dietpi.com/downloads/images/testing/
I'm still testing those before moving to stable downloads, but so far all works pretty good.

The kernel itself can be upgraded as well with the matching firmware package from here: https://dietpi.com/downloads/binaries/

Will ship this upgrade with next DietPi update, after some more testing and probably little enhancements to the kernel config.
