  31          There was a version of the nouveau DDX that relied on legacy
  32          ctx ioctls not erroring out. But that was back in time a long
  33          ways, so offer a way to disable it now. For uapi compat with
  34          old nouveau ddx this should be on by default, but modern distros
  35          should consider turning it off.
