Hi, here's the qemu patch that implements the new adapter indicators ccw in virtio-ccw and injects adapter interrupts for the devices enabled for it.

Hi, here's the current implementation of virtio-ccw adapter interrupts in qemu. Code is unchanged, only rebased against current master.

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

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
