This is what I'm seeing too. The additional ioctl that directfb is calling
are missing in the mv kernel. Mayber they have a patch that did not get into
the sources for directfb. I'm currently using directfb-1.1.1
I have it working via the fbdev. I can display to a rgb16 osd0 in 720x480
(fb0) mode.
We also use vid0 in rgb24 1280x720 (fb1) for our gui app (non-directfb).
however the format that the davinci stores rgb24 is like big endian, however
it is a little endian arm. I can get rgb24 to work too, but the colors are
wrong dues to the rgb ordering.
I will need to get vid0 1280x720 working in eitehr rgb24 or yuv422. osd0 has
an internal buffer problem in the osd0 window that TI is aware of in the
davinci which cause video tearing. so osd0 is not acceptable.
