There is no Hurd PCI driver (yet). The only PCI code being used is a temporary glue into GNU Mach. Yes, an interface between that and userspace should be designed, etc. But since it's a temporary glue, it's not really worth doing it right now. Still people would like to already try Xorg. > It just seems lazy to add a direct to hw code again in userspace when > clearly the kernel should be able for it, Depends on the kernel. A kernel could very well not deal with PCI at all and let userspace agree on using a "PCI server", that could for instance use libpciaccess. > not that I really mind, I'm just hoping other OSes don't get this > lazy, which marking this code as generic x86 might make them. I understand your concern. I still believe it is more helpful to provide this in the interim than to let yet another barrier from Xorg support for exotic kernels.
