Re: AMD To Release GPU Specifications Without NDA!
It looks promising but it's not there yet.
Even just full 2D specs to implement the base including multihead, TV, XV would be a step forward.
I wouldn't bet on "free time". So far a lot of Xorg gruntwork has been payed for by a variety of companies. This is a big issue and people are willing to steamroller into it, including monetary contributions.
