From ba110db8e1bc206c13fd7d985e79b033f53bfdea Mon Sep 17 00:00:00 2001 From: Joel Fernandes Date: Fri, 6 Feb 2026 08:52:38 +1000 Subject: gpu: Move DRM buddy allocator one level up (part two) Move the DRM buddy allocator one level up so that it can be used by GPU drivers (example, nova-core) that have usecases other than DRM (such as VFIO vGPU support). Modify the API, structures and Kconfigs to use "gpu_buddy" terminology. Adapt the drivers and tests to use the new API. The commit cannot be split due to bisectability, however no functional change is intended. Verified by running K-UNIT tests and build tested various configurations. Signed-off-by: Joel Fernandes Reviewed-by: Dave Airlie [airlied: I've split this into two so git can find copies easier. I've also just nuked drm_random library, that stuff needs to be done elsewhere and only the buddy tests seem to be using it].
