Well just keep it. As I said please don't change anything here. Dropping DRM_AUTH from the driver IOCTLs was sufficient to work around the problems at hand far as I know. And stopping those two at least prevents userspace to abuse this even more. On the other hand I haven't seen any NAK on dropping DRM_AUTH from them. Christian. Third route that I see is doing driver_name == "amdgpu" || driver_name == "radeon" in core. If you have alternative solution I'm all ears. -Emil
