Sorry for confusing, it was delayed for other reasons internal.

I am not familiar about the DRM, and I'd like to know if the DRM driver will be
support, should I also develop the libdrm too ? Or just coding in kernel level ?
Is there any Document about how to have /dev/fbX device to use ?

If possible, I'd like this could be accept for this time. And I will add the DRM
Version later(for developing and testing will take a long time).

Thanks very much,
