Hi, following are the qemu parts for supporting virtual channel I/O and the new virtio-ccw transport. Patch 1 pulls in the new interface definitions. Patch 2 contains the ground work for supporting virtual subchannels (kvm only). Patch 3 implements the new virtio-ccw transport. Patch 4 makes virtual subchannels available for !kvm as well. Note that this patch is completely untested; it basically contains my initial channel subsystem code before I moved most of it into the kernel. Patch 5 is a hack needed to make virtio-ccw work with the alias stuff for now. The correct solution is to rework the virtio layering as has been proposed for virtio-mmio (see http://comments.gmane.org/gmane.comp.emulators.qemu/148224). The patches still have some TODOs in them (but nothing major), and likely some things need to be done differently. I hope, however, that the architectural part is fine.
