drm: nova-drm: add initial driver skeleton Add the initial nova-drm driver skeleton. nova-drm is connected to nova-core through the auxiliary bus and implements the DRM parts of the nova driver stack. For now, it implements the fundamental DRM abstractions, i.e. creates a DRM device and registers it, exposing a three sample IOCTLs. DRM_IOCTL_NOVA_GETPARAM - provides the PCI bar size from the bar that maps the GPUs VRAM from nova-core DRM_IOCTL_NOVA_GEM_CREATE - creates a new dummy DRM GEM object and returns a handle DRM_IOCTL_NOVA_GEM_INFO - provides metadata for the DRM GEM object behind a given handle I implemented a small userspace test suite [1] that utilizes this interface.

rust: macros: remove `module!`'s deprecated `author` key Commit 38559da6afb2 ("rust: module: introduce `authors` key") introduced a new `authors` key to support multiple module authors, while keeping the old `author` key for backward compatibility. Now that most in-tree modules have migrated to `authors`, remove: 1. The deprecated `author` key support from the module macro 2. Legacy `author` entries from remaining modules Signed-off-by: Guilherme Giacomo Simoes <trintaeoitogc@gmail.com> Acked-by: Andreas Hindborg <a.hindborg@kernel.org> Reviewed-by: Benno Lossin <lossin@kernel.org> Acked-by: Danilo Krummrich <dakr@kernel.org> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Link: https://lore.kernel.org/r/20250609122200.179307-1-trintaeoitogc@gmail.com [ Reworded slightly. - Miguel ] Signed-off-by: Miguel Ojeda <ojeda@kernel.org> 2025-06-09 09:22:00 -03:00
