Oracle's response to my request has been less than preferable. I have decided to do this myself over the next year or two, but will need a lot of mentoring.

I currently have the following conceptions about this project:

1. The first order of business will be to establish a skeleton driver that uses the softpipe for everything.
2. TGSI instructions will be translated to OpenGL 2.1 and sent through VirtualBox's existing Chromium pipeline, theoretically requiring no changes to VirtualBox itself.

But for initial questions:

1. Does a DRM driver need to be implemented?

I appreciate any help I can get.
