I've seen that you dropped this patch: https://patchwork.kernel.org/patch/10445393/

Is that patch correct or incorrect? In case it is incorrect, do you have an idea how should fbdefio be used properly on KMS drivers?

I suppose I was wondering what use fbdefio really has, modern code should be using KMS interface and the KMS dirty handling should be able to cover those cases.

I don't really like the maintainability decrease moving to in-driver page handling causes vs using shmem.

I think tinydrm has the same problem of shmem+fbdefio, could be worth it to chat with Noralf. Adding him. -Daniel
