-config DRM_RADEON_UMS
- bool "Enable userspace modesetting on radeon (DEPRECATED)"
- depends on DRM_RADEON
- help
- Choose this option if you still need userspace modesetting.
-
- Userspace modesetting is deprecated for quite some time now, so
- enable this only if you have ancient versions of the DDX drivers.
