Thanks, but how does Linux kernel ensures that it can talk to all framebuffer devices out there? Does it come with a generic implementation that all GPU vendors support?

There indeed is a standardized interface provided via EFI: https://docs.kernel.org/fb/efifb.html https://docs.kernel.org/fb/efifb.html
