Next version of virtio-1 patches for qemu. Only change from v2 is splitting out the vring accessors into a separate header file - should hopefully fix the build issues. Cornelia Huck (9): virtio: cull virtio_bus_set_vdev_features virtio: support more feature bits s390x/virtio-ccw: fix check for WRITE_FEAT virtio: introduce legacy virtio devices virtio: allow virtio-1 queue layout

Yet another version of the virtio-1 support patches. This one has seen some (very) light testing with the virtio-1 guest support patches currently on vhost-next. Changes from v3: - Add support for FEATURES_OK. We refuse to set features after the driver has set this in the status field, and we allow to fail setting the status if the features are inconsistent. - Add missing virtio-1 changes

Another iteration of virtio-1 patches for qemu, as always available on git://github.com/cohuck/qemu virtio-1 This one seems to work together with the current vhost-next patches (well, I can ping :) Changes from v4: - add helpers for feature bit manipulation and checking - use 64 bit feature bits instead of 32 bit arrays - infrastructure to allow devices to offer different sets of feature bits

And yet another iteration of virtio-1 support in qemu, tested with the latest virtio kernel patches. Find it at git://github.com/cohuck/qemu virtio-1 Changes from v5: - fixed stupid bug in "virtio: support more feature bits": we need to define a proper prop backend for 64 bit wide handling... - don't negotiate revision 1 unless VERSION_1 is offered - use 64 bit wide features
