Ah, right. test/emulate.pl reads virtio-pci feature to decide what Virt I/O
transport to use. Maybe the MMU incompatibility is fixed now with your
recent DMA rework or maybe we still have 1:1 mapping assumptions in the
virtio code itself. If you could give it a quick test with CONFIG_MMU=n
and see if it works, that would be great. Something like this should do it:
/usr/bin/qemu-system-mips64el -M malta -cpu 5KEf -m 256M \
-bios barebox-qemu-malta.img.swapped -serial mon:stdio -trace file=/dev/null \
-drive if=none,file=/src/barebox-rockchip/somealigned.img,format=raw,id=hd0 \
-device virtio-blk-pci,disable-legacy=on,disable-modern=off,drive=hd0
(Above was generated by ./test/emulate.pl $config -n --blk=somealigned.img)
You should see a /dev/virtioblk* device if everything is enabled and working.
