Hi,
here's the latest version of my patchset introducing virtio-ccw.
This has been reworked with the changed kernel interface: qemu
will now handle all channel I/O requests (except the I/O interrupt
related ones that are handled in-kernel in the kvm case). This
avoids duplicating code in qemu and in kvm.
There are some misc fixes as well (mainly related to virtio-ccw).
Use of mutexes has hopefully been exorcised for now.
Unfortuately, patch 2 is now rather large - but I couldn't think
of a good way to split it up.
I still know of various things that need looking into (memory
accesses, for one), but I'd like some feedback about the new
interface first.
Cornelia Huck (3):
Update linux headers.
s390: Virtual channel subsystem support.
s390: Add new channel I/O based virtio transport.
