Hi Dave, Sima, this is the weekly PR for drm-misc-next. It has quite a number of highlights: * There is the new device wedge event, which allows drivers to report unresponsive hardware to user space via a uevent. Drivers for AMD and Intel HW already use the functionality. * The i2c subdirectory has been removed after all code has been moved elsewhere. * Atomic helpers now support asyncronous pageflips on arbitrary planes. Amdgpu already supports this. And of course there's the usual amount of fixes, cleanups and small additions. Best regards Thomas drm-misc-next-2025-02-20: drm-misc-next for v6.15: UAPI Changes: device-wedged events: - Let's drivers notify userspace of hung-up devices via uevent Cross-subsystem Changes:
