Below you can find a patch with a proposed solution. Our frambuffer driver source code is provided separately, but right now it requires "cfb_fillrect", "cfb_copyarea" and "cfb_imageblit" to be provided by the kernel. Our current kernel fork (based on 3.4) hardcodes FB_CFB_FILLRECT, FB_CFB_COPYAREA and FB_CFB_IMAGEBLIT to yes. Since we are in the process of migrating to 4.x and upstreaming changes along the way, we would like to know if the patch below is the way to go with it or if you have suggestions to improve it.
