jhb 2008-09-10 18:06:08 UTC FreeBSD src repository Modified files: sys/amd64/pci pci_cfgreg.c sys/i386/pci pci_cfgreg.c Log: SVN rev 182910 on 2008-09-10 18:06:08Z by jhb Some K8 chipsets don't expose all of the PCI devices on bus 0 via PCIe memory-mapped config access. Add a workaround for these systems by checking the first function of each slot on bus 0 using both the memory-mapped config access and the older type 1 I/O port config access. If we find a slot that is only visible via the type 1 I/O port config access, we flag that slot. Future PCI config transactions to flagged slots on bus 0 use type 1 I/O port config access rather than memory mapped config access.
