Supporting interop with any device is always possible. It depends on which drivers we need to interoperate with and update them. We've already found the path forward for amdgpu. We just need to find out how many other drivers need to be updated and evaluate the cost/benefit aspect.

That could only be a problem for A+I Laptops.
Since I think you mentioned you'd only be enabling this on newer chipsets, won't it be a problem for A+A where one A is a generation behind the other?
I'm not really liking where this is going btw, seems like a ill thought out concept, if AMD is really going down the road of designing hw that is currently Linux incompatible, you are going to have to accept a big part of the burden in bringing this support in to more than just amd drivers for upcoming generations of gpu.
