Merge tag 'drm-next-2025-05-28' of https://gitlab.freedesktop.org/drm/kernelPull drm updates from Dave Airlie: "As part of building up nova-core/nova-drm pieces we've brought in some rust abstractions through this tree, aux bus being the main one, with devres changes also in the driver-core tree. Along with the drm core abstractions and enough nova-core/nova-drm to use them. This is still all stub work under construction, to build the nova driver upstream. The other big NVIDIA related one is nouveau adds support for Hopper/Blackwell GPUs, this required a new GSP firmware update to 570.144, and a bunch of rework in order to support multiple fw interfaces. There is also the introduction of an asahi uapi header file as a precursor to getting the real driver in later, but to unblock userspace mesa packages while the driver is trapped behind rust enablement. Otherwise it's the usual mixture of stuff all over, amdgpu, i915/xe, and msm being the main ones, and some changes to vsprintf. new drivers: - bring in the asahi uapi header standalone - nova-drm: stub driver rust dependencies (for nova-core): -
