[RFC PATCH 0/8] [RFC] DRM Rust abstractions and Nova

[Danilo Krummrich]

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].
