You can either enable it in your .config directly, or add "select DRM_TTM_HELPER" in the out-of-tree module. IMO convenience for out-of-tree modules is not really a consideration, because adding new user selectable kconfig options is an inconvenience for in-tree users. BR, Jani. -- Jani Nikula, Intel
