This is a userspace-visible change, but I guess it's unavoidable. Will anything break? Also, I dislike this approach of duplicating the firmware device tree path in sysfs. Are GX/ibmebus devices guaranteed to be children of the same node in the OF device tree? If so, their unit addresses will be unique, and therefore suitable values for bus_id. I believe this is what the powerpc vio bus code does. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
