Hello, I found that qlge is broken on PPC, and it got broken after commit 06a1cbafb253c4c60d6a54a994887f5fbceabcc0. It happens because dev->pcie is not set on PPC, because the function set_pcie_port_type(), who sets dev->pcie, is not being called on PPC PCI code.You mean dev->is_pcie? Why isn't pci_scan_device calling pci_setup_device for you? That should do the proper PCIe init depending on the device, along with extracting other device info...
Cc'ing Ben for PPC. Ben, should PPC use pci_scan_device when probing its root busses? Sounds like it just uses pci_device_add for each one it finds instead? If you don't actually need scanning (though what about hotplug?) we can move the call to device_add instead... -- Jesse Barnes, Intel Open Source Technology Center
