[PATCH RFC v6 11/20] s390x/virtio-ccw: support virtio-1 set_vq format
Support the new CCW_CMD_SET_VQ format for virtio-1 devices.
While we're at it, refactor the code a bit and enforce big endian
fields (which had always been required, even for legacy).

[PATCH RFC v2 00/12] qemu: towards virtio-1 host support
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

[PATCH RFC v3 00/12] qemu: towards virtio-1 host support
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

[PATCH RFC v4 00/16] qemu: towards virtio-1 host support
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

I've mainly focused on:

- virtio-ccw new/changed commands

[PATCH RFC v5 00/19] qemu: towards virtio-1 host support
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

from MemoryListener->region_[add,del]() -> vhost_set_memory() into
final MemoryListener->commit() -> vhost_commit() callback.
