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

support, should I also develop the libdrm too ? Or just coding in kernel
level ?
For simple drm drivers (this looks like it would be a simple one), I
don't think there's any need for libdrm support. The generic DRM
interfaces should be enough, so just kernel level coding needed.
That's to say, if I am using the X11 server without any code in usrspace,
If the DRM driver will support /dev/fbX, it could work correctly ?
Yes. DRM offers helper code to add /dev/fbX with not too many lines. You
can look at the docs and drm_fb_helper.c.
And X11 should work fine on top of that, using the X11 fbdev support.
