[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.

[RFC PATCH v2 0/2] KVM: s390: virtio-ccw adapter interrupts.
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

[PATCH 0/1] virtio/s390: one fix
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?
