Modern GPUs are extraordinarily complex HW and to write a decent driver will take appropriate effort. I understand that open source "infected" people (like me) prefer having the detailed HW documentation but we shouldn't refuse the vendor's efforts to provide good driver to us. I haven't understood much of Mr. Zander's questions but I am pretty sure some readers did and probably have been talking to him off-list. I also tend to believe that his requests for features were based on good understanding of FreeBSD kernel internals (better that mine and probably also yours) and if we add the features or help him effectively use what's there everyone will benefit. > Maybe not for the latest GPUs but I'm sure a lot people would be happy > if they could use not-so-new NVidia hardware on FreeBSD/amd64.

How about the proprietary > nforce4 chipset? They well may have reasons not to disclose everything. There is probably lot of their market success hidden in the full specs. I bet that Mr. Zanders can't answer the question (and definitely can't decide to give the specs) anyway. And - again - it will probably take a couple of very skilled programmers' years' time to write good driver from scratch. > > Cheers.
