[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
bits

[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
