The AST2600/ASPEED driver treats root bus 0x80 specially: only two device addresses are usable on the root bus, addr 0 (ASPEED host bridge) and addr 8. To attach endpoints without code changes, the test places a QEMU PCIe root port at 0x80:08.0 and hangs e1000e behind it so the endpoint enumerates on bus 0x81. The test appends: -device pcie-root-port,id=3Droot_port0,slot=3D1,addr=3D8,bus=3Dpcie.0 -device e1000e,netdev=3Dnet0,bus=3Droot_port0 -netdev user,id=3Dnet0 It then verifies enumeration with lspci: 0001:80:00.0 Host bridge: ASPEED Technology, Inc. AST1150 PCI-to-PCI Bridge 0001:80:08.0 PCI bridge: Red Hat, Inc. QEMU PCIe Root port 0001:81:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network Connection This is a temporary solution that allows attaching multiple PCIe devices while the ASPEED drivers does not support placing endpoints directly on bus numbers 0x80.
