This patch series implements some basic DRM Rust abstractions and a stub implementation of the Nova GPU driver.
Nova is intended to be developed upstream, starting out with just a stub driver to lift some initial required infrastructure upstream. A more detailed explanation can be found in [1]. This patch series is based on the "Device / Driver and PCI Rust abstractions" series [2]. The DRM bits can also be found in [3] and the Nova bits in [4].
