Again to clarify, I'm not so much interesting in sharing code here - I
know it'll be nigh to impossible by having looked through nouveau already
and quickly glossed through your stuff. I see the value is just in having
a minimal set of common idioms that we can use to build cool stuff like
resource management.

Think of gem, which is actually about next to nothing. There's a the flink
stuff and a common close ioctl and recently also a dummy create unusable
for anythine else than boot spalsh screens. Plus the shmem backing store
which seems to be not so much in favour with embedded chips, i.e doesn't
really count. Ridiculous compared to all the other stuff required to draw
triangles on a gpu, but good enough to make things like dri2 and wayland
possible.

Cheers, daniel
