| | | | | | | | | | | | | | | | | | | | | | | | support machines having multiple independently numbered PCI domains and don't support reenumeration without ambiguity amongst the devices as seen by the OS and represented by PCI location strings. 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 <sys/pciio.h> potentially need to be recompiled.

| | | | | | | | | | | | | | | | | | | | cardbus_cis.c to this file, some code was not merged and thus resource list entries were invalid. They didn't have a resources attached to them. However, the problem was masked for some time later, because newer resources list entries were added to the head of the list, and resource_list_find() always returned the first matching resource list entry. Usually the underlying driver allocated a valid resource and added it to the head of the list, and invalid one wasn't used. In rev. 1.174 of subr_bus.c the sorting of resource list entries was reversed demasking the problem in cardbus_alloc_resources().

| | | | | | | | | | | | | | | | | yet I only changed one of them. So when we loaded drivers, we'd fail to allocate resources correct. This pointed out that we were doing the wrong thing when we failed to attach a child. We released all the resources and almost deleted the child. Instead, we should keep the resources allocated so when/if a driver is loaded, we can go w/o having to allocate them. We use pci_cfg_save/restore to restore the BARs with these resources. This seems to fix the problems that we were seeing that I thought might have magically gone away in the last revision of cardbus.c (but really didn't). Noticed by: avatar (nicely done!)
