I'm back now.
Trying to reproduce this with mainline kernel (arm64 defconfig) and the
following command line:
qemu-system-aarch64 \
-M virt,nvdimm=on,gic-version=3 -m 4g,maxmem=8G,slots=8 -cpu max -smp 4 \
-bios /usr/share/qemu-efi-aarch64/QEMU_EFI.fd \
-nographic -no-reboot \
-kernel Image \
-initrd rootfs.cpio.bz2 \
-device pcie-root-port,port=0,id=root_port13,chassis=0,slot=2 \
-device x3130-upstream,id=sw1,bus=root_port13,multifunction=on \
-device e1000,bus=root_port13,addr=0.1 \
-device xio3130-downstream,id=fun1,bus=sw1,chassis=0,slot=3 \
-device e1000,bus=fun1
But the resulting PCIe topology is pretty flat:
# lspci
00:00.0 Host bridge: Red Hat, Inc. QEMU PCIe Host bridge
00:01.0 Ethernet controller: Red Hat, Inc. Virtio network device
I wonder what I'm missing here? Do I need to enable additional drivers
to get the topology to resemble yours?
