I'm getting an error message when trying to talk to some custom hardware: dx83xx 0001:43:00.0: device not available because of BAR 0 [0xa1000000-0xa1ffffff] collisions I see in setup-res.c that this message comes out when there is no parent for a device resource..../... It mostly happens in arch/powerpc/kernel/pci-common.c and the generic setup-res.c Try #define DEBUG at the top (before the #includes) of pci-common.c and pci_32.c (remove the exiting #undef in the last one) and send us the full dmesg log, along with the output of cat /proc/iomem
Have you set any specific flags ? IE. Modified the value of ppc_pci_flags from what the 4xx code sets originally ? It does look to me like some of your device BARs have been setup already by the firmware in a way that conflict with the way you configure your ranges, and the kernel doesn't appear to detect nor try to remap that which would happen if you have the "probe only" flag set. IE. On your c0000000 bus, you have memory at 90000000 CPU space mapped to 80000000 PCI space. However, when probing, the kernel finds: pci 0001:41:00.0: reg 10 32bit mmio: [0x90000000-0x9001ffff] IE. A BAR was already set with a value of 90000000 PCI-side which is out of the bounds you have for your bus. Maybe you really want to configure that second bus to have CPU 90000000 mapped to 90000000 PCI-side ? (IE. a 1:1 mapping). That would be something to fix in your "ranges" property. Cheers, Ben.

Cheers, Ben.Thanks for the help! PCIe 0 has an FPGA connected - it is behaving as expected. PCIe 1 has the PLX PCIe switch followed by a pair of ASICs - they are the ones generating the error.
