I am a newbi in this field .. The DU doesn't have any scaler, you will need to use an external scaler, such as the one included in the VSP (using OpenGL for scaling is also an option if you have support for the GPU). No kernel modification is needed for this, the DU and VSP are both supported in mainline with a DRM/KMS and V4L2 driver respectively. -- Regards, Laurent Pinchart
