[Qemu-devel] [PATCH 3/3] S390: Don't compile in virtio-pci
As soon as virtio-pci.c gets compiled and used on S390 the internal qdev magic gets confused and tries to give us PCI devices instead of S390 virtio devices. Since we don't have PCI on S390, we can safely not compile virtio-pci at all. In order to do this I added a new config option "CONFIG_VIRTIO_PCI" that I enabled for every platform except S390. Thanks to this the change should be a complete nop for every other platform.

We don't even do MMIO :-). In that case you should also rip out all PCI cards.

There are some real devices with PCI (JavaStations) though.
