Maybe I'm misunderstanding what you mean, but what I'm hearing you say is "modify src/mesa so that every single classic driver will have to be churned significantly or stop working", which sounds much worse than options 1 or 2, because the main problem with classic is that i965 is the only classic driver that's really being maintained. > I don't like forking src/mesa/main/* because really 99% of it is just > a GL frontend implementation, most bugs in it will be in a fork and > vice-versa, I'd rather refine the abstraction between mesa and > backends if possible to reduce the overheads. > > I'm probably not convinced that any benefit is worth accepting 1 or 2 > above, but hey I've been persuaded before to do crazy things. > > Dave. > _______________________________________________ > mesa-dev mailing list > mesa-dev@lists.freedesktop.org > https://lists.freedesktop.org/mailman/listinfo/mesa-dev
