Ben,
The DM6467 VPIF lacks the OSD peripheral present in the VPSS of other Davinci
devices; in particular it has no color
space conversion hardware. This being said there is no way to effectively
display RGB frame buffers, theoretically
you could write a RGB->YCbCr conversion routine and frame buffer driver in
software but this would have significant
overhead, in any case only video (YCbCr) through V4L2 is supported for DM6467
as things are today (I know of no plans
for FB on DM6467).
I'd say the video driver does not care whether it shows a video frame or an X11 screen, the only issue is that
converting RGB to YUV will lose 1/2 of the color resolution, so the X11 will not look very nice.
