I don't think the in/out stuff should be moved into drm since I'm fairly sure that these functions are used on platforms without drm support. libpciaccess might be a more appropriate place, although in/out are really legacy ISA interfaces and therefore could be needed on machines that don't have a PCI bus. That said, the way in/out are used in the xserver and associated (PCI) drivers is really bogus. Their usage should be replaced by a mechanism similar to how memory mapped io is handled. PCI drivers should really use pci_device_map_range() to "map" io space just like mmio space such that they can work on architectures that have multiple PCI domains. _______________________________________________ xorg-devel mailing list xorg-devel@lists.x.org http://lists.x.org/mailman/listinfo/xorg-devel
