Hi, all We'd like to add PCI-to-PCI Bridge for qemu(kvm) for x86/x86_64 box. I read the code, and find the following hardware calls the function pci_bridge_initfn(): 1. apb 2. ioh3420 3. xio3130 ioh3420 and xio3130 is for PCIe, and apb is for sparc box. I do not find any PCI-to-PCI bridge for x86/x86_64 box. Is there some projects we can join ? If not, we'll start
There is one in hw/dec_pci.c. This isn't compiled by default, but that is just a configuration issue. I had some IRQ routing issues with that one though.
There is also http://patchwork.ozlabs.org/patch/103058/ which works fine after fixing the double irq_num. Michael wants implement hotplug support before merging it though.
cheers, Gerd
