[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. Signed-off-by: Cornelia Huck <cornelia.huck at de.ibm.com> --- hw/s390x/css.c |

[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. I've been able to start guests both with and without the

[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.
