yeah, it was going to be more re-work, and I'm neck deep in
gpuvm/vm_bind.. I just wanted to land this since it is a pita (and
error prone) to rebase as more gpu's get added ;-)
It isn't entirely unlike how we handle gpu gen specific options in
mesa, where we have a somewhat bigger set of options, so I wouldn't
say that this approach was worse than extending adreno_info.. just
different..
