Recent changes in s390x made pci support dependant on the zpci cpu feature, which is not provided on all models (and not on by default). This means we cannot instatiate pci devices on a standard qemu invocation for s390x. Moreover, the zpci instructions are not even wired up for tcg yet, so actually doing anything with those pci devices is bound to fail on tcg.
For 040, 051, 139, and 182, this can be fixed by switching to virtio-ccw from virtio-pci on s390x. 051 also needs a bit of post-processing on the output. For 067, it is easier to switch to virtio aliases, which will pick virtio-ccw on s390x and virtio-pci elsewhere. It also exercises the aliasing path. v1->v2: - avoid adding new reference output by adding post-processing to 051 and switching to aliases for 067 Cornelia Huck (3): iotests: use -ccw on s390x for 040, 139, and 182 iotests: use -ccw on s390x for 051 iotests: use virtio aliases for 067 tests/qemu-iotests/040 | 6 +++++- tests/qemu-iotests/051 | 12 +++++++++++- tests/qemu-iotests/051.out | 2 +- tests/qemu-iotests/051.pc.out | 2 +- tests/qemu-iotests/067 | 3 ++- tests/qemu-iotests/067.out | 2 +- tests/qemu-iotests/139 | 12 ++++++++++-- tests/qemu-iotests/182 | 13 +++++++++++-- 8 files changed, 42 insertions(+), 10 deletions(-) -- 2.13.5
