On !386 you additionally need to update to xorg-server-1.4_1,1. Regarding common ports affected by the introduction of support for PCI domains these two ports should be it. Other consumers of potentially also need to be recompiled and adjusted, f.e. sjog needs to be recompiled but should need no changes. Generally, if a port uses pc_bus it also needs to deal with pc_domain now. Marius marius 2007-09-30 11:05:18 UTC FreeBSD src repository Modified files: .

This includes introducing a function pci_find_dbsf(9) which works like pci_find_bsf(9) but additionally takes a domain number argument and limiting pci_find_bsf(9) to only search devices in domain 0 (the only domain in single-domain systems). Bge(4) and ofw_pcibus(4) are changed to use pci_find_dbsf(9) instead of pci_find_bsf(9) in order to no longer report false positives when searching for siblings and dupe devices in the same domain respectively. Along with this change the sole host-PCI bridge driver converted to actually make use of PCI domain support is uninorth(4), the others continue to use domain 0 only for now and need to be converted as appropriate later on. Note that this means that the format of the location strings as used by pciconf(8) has been changed and that consumers of potentially need to be recompiled.
