The problem is not caused by mono kernel. Just because AMDGPU driver was developed in mono style. i.e. they include the code of all generations in one driver. In monolithic kernel, the developer can develop drivers with “micro” style. e.g. Intel’s GPU driver doesn’t use mono style, they created a new driver when they changed GPU hardware architecture.

Monolithic kernel is a concept about address space. If all parts of a kernel are running in the same address space, this is a monolithic kernel, otherwise it’s a micro kernel.

This problem is about how to split parts, but not how to place parts in memory.

In my opinion, that’s because X11 lacks proper abstract for many things like screenshot, screencast, color managerment and etc, so the applications have to use many X11 implementation details to implement these features. It leads to high-coupling code with X11 so move their code to wayland and ensuring it works correctly and is consistent with the old behavior is difficult.
