1. DRM userspace work.  Need a DRM enabled xf86 driver for X.org. 
• http://cgit.freedesktop.org/xorg/driver/xf86-video-armsoc/
• Expect some related work like that done by ARM as described here: http://lists.x.org/archives/xorg-devel/2012-May/031250.html
• There also might be some changes needed in libdrm to add support for the HiKey platform.

xf86-video-modesetting should be enough, that used DRM/KMS for modesetting and will optionally use GL to accelerate 2d operations. 

Thanks  for your feedback.
Actually, this is my first time to do X11 integration work. I'm not sure if we need to write some code on xf86 driver for X.org. I'll find out that if xf86-video-modesetting is enough.
It seems you have experience on X11. Can i ask you some questions if i encounter some on X11.
Thanks very much.
