Hello, The current libpci branch uses the pciutils library (/usr/lib/libpci*.so*) to discover the hierarchy of PCI bridges/devices. pciutils works on many platforms, including windows (even if I never actually tried it). Unfortunately, there is no official support for MacOSX. I tried libpciaccess (used by X) which offers almost the same abilities but it doesn't seem to work on MacOSX either. Does anybody have any idea what we could use on MacOSX?
