Merge tag 'drm-next-2023-08-30' of git://anongit.freedesktop.org/drm/drm
Pull drm updates from Dave Airlie: "The drm core grew a new generic gpu virtual address manager, and new execution locking helpers. These are used by nouveau now to provide uAPI support for the userspace Vulkan driver. AMD had a bunch of new IP core support, loads of refactoring around fbdev, but mostly just the usual amount of stuff across the board. core: - fix gfp flags in drmm_kmalloc gpuva: - add new generic GPU VA manager (for nouveau initially) syncobj: -
