this archive contains kernel+initrd. I run it this way:
qemu-system-arm -append root=LABEL=debvm -nographic -machine type=virt \
-drive media=disk,format=raw,file=vmlinuz,if=virtio,snapshot=on \
-no-user-config -m 1G -kernel vmlinuz -initrd initrd.img
This is actually even more fishy.
The reproducer needs -cpu max to "work." Without -cpu max, it
fails to recognize virtio pci devices in both cases - in 8.2.0
with or without the commit in question (b8f7959f28c4f36496).
Only with -cpu max it works after reverting b8f7959f28c.
Additional kernel message in case when it doesn't work:
[ 1.372841] pci-host-generic 4010000000.pcie: \
can't claim ECAM area [mem 0x10000000-0x1fffffff]: \
address conflict with pcie@10000000 [mem 0x10000000-0x3efeffff]
which isn't generated in case everything's ok.
