Add the initial nova-core driver stub. nova-core is intended to serve as a common base for nova-drm (the corresponding DRM driver) and the vGPU manager VFIO driver, serving as a hard- and firmware abstraction layer for GSP-based NVIDIA GPUs. The Nova project, including nova-core and nova-drm, in the long term, is intended to serve as the successor of Nouveau for all GSP-based GPUs. The motivation for both, starting a successor project for Nouveau and doing so using the Rust programming language, is documented in detail through a previous post on the mailing list [1], an LWN article [2] and a talk from LPC '24. In order to avoid the chicken and egg problem to require a user to upstream Rust abstractions, but at the same time require the Rust abstractions to implement the driver, nova-core kicks off as a driver stub and is subsequently developed upstream.
