Probably diverged too much already, and on top the big part is the command
submission, and that's entirely driver/hw specific. But etnaviv is a plain
gem driver which uses per-bo locking, and there's all the ttm drivers with
similar designs, so there's plenty of templates. But it's not just
copypasta for sure.
