-I have also heard some general comments that regardless of the relationship
between GBM and the new allocator mechanisms, it might be time to move GBM
out of Mesa so it can be developed as a stand-alone project. I'd be
interested what others think about that, as it would be something worth
coordinating with any other new development based on or inside of GBM.
Having a GBM frontend is one thing I've been pondering as well.
Regardless of exact solution wrt the new allocator, having a clear
frontend/backend separation for GBM will be beneficial.
I'll be giving it a stab these days.
I'm not sure what you mean by that. It currently has something that looks
like separation but it's a joke. Unless we have a real reason to have
anything other than a dri_interface back-end, I'd rather we just stop
pretending and drop the extra layer of function pointer indirection entirely.
Gah! I didn't read Rob's email before writing this. It looks like there
is a use-case for this. I'm still a bit skeptical about whether or not we
really want to extend what we have our if it would be better to start over
and just require that the new thing also support the current GBM ABI.

Disclaimer: Mostly thinking out loud, so please take the following
with grain of salt.
On the details wrt the new allocator project, I think that having a
new lean library would be a good idea.
One could borrow ideas from GBM, but by default no connection between
the two should be required.
That might lead to having a the initial hurdle of porting a bit
harder, but it will allow for more efficient driver implementation.
