gpu: nova-core: add initial driver stubAdd the initial nova-core driver stub.nova-core is intended to serve as a common base for nova-drm (thecorresponding DRM driver) and the vGPU manager VFIO driver, serving as ahard- 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 anddoing so using the Rust programming language, is documented in detailthrough a previous post on the mailing list [1], an LWN article [2] and atalk from LPC '24.In order to avoid the chicken and egg problem to require a user toupstream Rust abstractions, but at the same time require the Rustabstractions to implement the driver, nova-core kicks off as a driverstub and is subsequently developed upstream.Link: https://lore.kernel.org/dri-devel/Zfsj0_tb-0-tNrJy@cassiopeiae/T/#u [1]Link: https://lwn.net/Articles/990736/ [2]Link: https://youtu.be/3Igmx28B3BQ?si=sBdSEer4tAPKGpOs [3]Reviewed-by: Alexandre Courbot Link: https://lore.kernel.org/r/20250306222336.23482-5-dakr@kernel.orgSigned-off-by: Danilo Krummrich List of files: /linux-6.15/drivers/gpu/nova-core/Makefile
