Right now, Mir is able to run on top of the free graphics driver stack, leveraging GBM, DRM and KMS to integrate with existing graphics hardware.

Right now, Mir does not run on desktop hardware that requires closed source drivers. However, we are in contact with GPU vendors and are working closely together with them to support Mir and to distill a reusable and unified EGL-centric driver model that further eases display server development in general and keeps cross-platform use-cases in mind.
