The edge kernel is a mainline kernel, hence many features of the RK3588 won’t work. However, you can just test it and report back what works and what not. I would love to switch to mainline kernel ASAP.
collabora is as well an experimental mix of mainline Linux with added hardware support by Collabora. Some more things will work, but it heavily changes, hence things may break with any update. By Collabora, these sources are aimed for upstreaming, for developers and testers, not for productive usage: Rockchip RK3588 upstream enablement efforts · GitLab
However, of course feel free to test it.
What I am actually aiming for is switching to the vendor branch, which is not in Armbian’s APT repositories yet. It is based on Rockchip kernel source (like legacy), but their recent Linux 6.1 sources, which were build up from scratch, while the 5.10 sources were only rebased since a long time, with a lot of crap accumulated, as well as Android and Linux intermixed. I’ll generate builds today, so you can test them.
EDIT: Build in progress: Armbian · MichaIng/DietPi@7da2b57 · GitHub
Can be found here once done: Index of /downloads/binaries/testing
I also started builds with vendor-boogie-panthor branch. This is the vendor branch, but with a new GPU driver developed by someone from Collabora: Release the panthor!
I guess this is part of the collabora branch already, hence this branch is between vendor and collabora.
