The whole discussion is mostly about the DC related code in the amdgpu driver and its interaction with core DRM/kernel code, i.e. mostly about code under drivers/gpu/drm/. It doesn't affect anything outside of that, certainly not how things are divided up between kernel and userspace. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
