• IOCTL_VIDEO_VALIDATE_CHILD_STATE_CONFIGURATION, in which the video port driver queries the miniport driver to determine whether the specified state for each child device in ChildStateArray is valid.

• IOCTL_VIDEO_SET_CHILD_STATE_CONFIGURATION, in which the video port driver requests the miniport driver to make the specified state change for each child device in ChildStateArray.
