[RFC PATCH v2] qemu: Adapter interrupts for virtio-ccw.
Hi,
here's the current implementation of virtio-ccw adapter interrupts in qemu.
Code is unchanged, only rebased against current master.

[PATCH RFC] s390/virtio-ccw: Adapter interrupt support.
Handle the new CCW_CMD_SET_IND_ADAPTER command enabling adapter interrupts
on guest request. When active, host->guest notifications will be handled
via global_indicator -> queue indicators instead of queue indicators +
subchannel I/O interrupt. Indicators for virtqueues may be present at an
offset.

[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 00/11] qemu: towards virtio-1 host support
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.

[PATCH RFC v6 00/20] qemu: towards virtio-1 host support
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

[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

[PATCH RFC 0/2] KVM: s390: virtio-ccw adapter interrupts.
Hi,
here's the guest driver support for adapter interrupts in virtio-ccw.
We use one summary indicator per page of indicators. For each device,
we try to find a space in an indicator where all of its virtqueues fit.
Locking probably needs some more love, but it seems to work fine so far.
