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.

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.

This patchset tries to go towards implementing both virtio-1 compliant and transitional virtio drivers in Linux. Branch available at git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux virtio-1 This is based on some old patches by Rusty to handle extended feature bits and endianness conversions. Thomas implemented the new virtio-ccw transport revision command, and I hacked up some

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
