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]. Changes in v2: ============== - split up the DRM device / driver abstractions in three separate commits - separate `struct drm_device` abstraction in a separte source file more cleanly - switch `struct drm_driver` and `struct file_operations` to 'static const' allocations - implement `Registration::new_foreign_owned` (using `Devres`), such that we don't need to keep the `Registration` alive on the Rust side, but automatically revoke it on device unbind - add missing DRM driver features (Rob) - use `module_pci_driver!` macro in Nova - use a const sized `pci::Bar` in Nova - increase the total amount of Documentation, rephrase some safety comments and commit messages for less ambiguity - fix compilation issues with some documentation example [1] https://lore.kernel.org/dri-devel/Zfsj0_tb-0-tNrJy@cassiopeiae/T/#u [2] Reply to this mail titled "Device / Driver and PCI Rust abstractions".
