From: Thomas Huth <th...@redhat.com> For the s390x target, it's possible to build the QEMU binary without CONFIG_VIRTIO_PCI and only have the virtio-mem device via the ccw transport. In that case, QEMU currently fails to link correctly:
/usr/bin/ld: libqemu-s390x-softmmu.a.p/hw_s390x_s390-virtio-ccw.c.o: in function `s390_machine_device_pre_plug': ../hw/s390x/s390-virtio-ccw.c:579:(.text+0x1e96): undefined reference to `virtio_md_pci_pre_plug' /usr/bin/ld: libqemu-s390x-softmmu.a.p/hw_s390x_s390-virtio-ccw.c.o: in function `s390_machine_device_plug': ../hw/s390x/s390-virtio-ccw.c:608:(.text+0x21a4): undefined reference to `virtio_md_pci_plug' /usr/bin/ld: libqemu-s390x-softmmu.a.p/hw_s390x_s390-virtio-ccw.c.o: in function `s390_machine_device_unplug_request': ../hw/s390x/s390-virtio-ccw.c:622:(.text+0x2334): undefined reference to `virtio_md_pci_unplug_request' /usr/bin/ld: libqemu-s390x-softmmu.a.p/hw_s390x_s390-virtio-ccw.c.o: in function `s390_machine_device_unplug': ../hw/s390x/s390-virtio-ccw.c:633:(.text+0x2436): undefined reference to `virtio_md_pci_unplug' clang: error: linker command failed with exit code 1 (use -v to see invocation) We also need to include the stubs when CONFIG_VIRTIO_PCI is missing.
