Hi, here's the next version of my virtio-1 qemu patchset. Using virtio-1 virtio-blk and virtio-net devices with a guest kernel built from <1416829787-14252-1-git-send-email-mst at redhat.com> still seems to work for the virtio-ccw transport. Changes from v1: - rebased against current master - don't advertise VERSION_1 for all devices, make devices switch it on individually

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

This patchset aims to get us some way to implement virtio-1 compliant and transitional devices in qemu. Branch available at git://github.com/cohuck/qemu virtio-1 I've mainly focused on: - endianness handling - extended feature bits - virtio-ccw new/changed commands Thanks go to Thomas for some preliminary work in this area. I've been able to start guests both with and without the

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
