No display on builds somwhere from 6.9 [nixos]

I am trying to install nixos on a pinetab2 (8/128) but cant get the latest image to boot. ("official" release from github.com/nabam/ nixos-rockchip)

also when i build the kernel 6.9.3 from kernel.org with the danctnix.patch, the os boots with a black screen.

i reported the issue "downstream" at nabam, but i guess, since i cant build it with the patch, the problem lies upstream.

the last booting build from nabam is 6.6 and i built a booting image with that older nabam commit and 6.8

bootlogs are in the downstream issue (fails during rockchipdrm stuff):
nabam/nixos-rockchip#23

Works fine for me on Buildroot and Arch.

ok.. i guess i have to apply some Kernel Compilation flags then.
sorry, its quite the first time i have to use custom kernels and i want to make a configuration for automatically updating my kernel with this source.
i somehow got a working 6.8 kernels with nabams config which includes automatically set modules from nixos for sd card installations.

i guess the guys at the "official" nixos pinetab repo have more of a clue.

my understanding was that i apply the patch on a clean kernel and clean distro and everything works out of the box (like on my laptop), but i guess i have to find the right compilation parameters, since i made all modules that i found related available in the initramdisk, but it still didnt show anything.

bit hard to find out since the compilation is quite complicated if made external or slow if local...
