Hi,
here's a set of patches for virtio-core and virtio-ccw, fixing a common
code issue and finally enabling virtio-1 for ccw devices.
The first issue was noted by Jason: We need to care about changed
ring sizes. We also want to support different ring sizes in ccw for
virtio-1 devices (existing code did not propagate changes to core).
The final patch enabling virtio-1 support also introduces a new property
that allows to specify a maximum revision. I don't see a need to fence
off legacy; the maximum revision approach instead allows us to easily
introduce new revisions and still cap at a revision for compat machines.
Cornelia Huck (4):
virtio: ring sizes vs. reset
virtio-ccw: support ring size changes
virtio-ccw: feature bits > 31 handling
virtio-ccw: enable virtio-1
