gpu: nova: fix rust-analyzer generation

2026-07-03T21:27:39+00:00

The rust-analyzer generator script recognizes a crate when its corresponding `.o` appears in the Rust source file's immediate `Makefile` or `Kbuild` file. Commit ca524e273c43 ("gpu: build nova-core and nova-drm from drivers/gpu/Makefile") moves the build rules for `nova-core` and `nova-drm` into `drivers/gpu/Makefile`, which results in the generator script ignoring these crates. Fix this by naming the crates' module as a comment in their respective `Makefile`; this is enough for the script to pick them up and restore `rust-analyzer` functionality on them.

gpu: build nova-core and nova-drm from drivers/gpu/Makefile

2026-06-29T09:28:38+00:00

A dependency between nova-core and nova-drm is about to be introduced, which requires nova-core to be built first. As this is not easily doable from separate directories, move both build targets to the first common parent, `drivers/gpu/Makefile`.

gpu: nova: Use module names consistently

2026-05-09T21:51:49+00:00

Update nova/Makefile and nova-core/Makefile so that nova-drm.ko and nova-core.ko are produced, matching the module names set in patch 1. Update drm::DriverInfo with the correct driver name and vendor description. Fix Kconfig help text for both drivers and the debugfs directory name in nova-core to match the new module names.

gpu: nova-core: add initial driver stub

2025-03-09T18:24:27+00:00

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.
