Replace duplicated code in all transports with a single wrapper in virtio.c. The only functional change is in virtio_mmio.c: if a buggy device sends us an interrupt before driver is set, we previously returned IRQ_NONE, now we return IRQ_HANDLED. As this must not happen in practice, this does not look like a big deal. See also commit 3fff0179e33cd7d0a688dab65700c46ad089e934 virtio-pci: do not

Michael, here's one fix for the virtio-ccw driver. Patch is against master, as your git branches on mst/vhost.git seem to be quite old. Is there some branch I can base my own branch on, or do you prefer to take patches directly anyway?

Hi, next version of the guest exploitation of virtio-ccw adapter interrupts. Changes from the last version: - adapt to latest kvm-next - changed housekeeping for indicator locations: we now use cacheline-sized and aligned areas - minor tweaks Cornelia Huck (2): KVM: s390: virtio-ccw: Handle command rejects. KVM: s390: virtio-ccw adapter interrupt support. arch/s390/include/asm/irq.h

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.

Enhanced virtualization protection technology may require the use of bounce buffers for I/O. While support for this was built into the virtio core, virtio-ccw wasn't changed accordingly. Some background on technology (not part of this series) and the terminology used. * Protected Virtualization (PV): Protected Virtualization guarantees, that non-shared memory of a guest that operates in PV
