[Qemu-devel] [PATCH 00/10] migration: s390x css migration |
Date: |

This patch set has a dual purpose: introduce proper migration for the
channel subsystem (css) and convert the migration of ccw devices to
vmstate. The state of the css was only partially migrated by the
virtio-ccw devices (was the only device type until recent), which was
good enough for a while.
Since the new vmstate infrastructure is used also for handling the
migration stream for legacy machines some bits are a bit convoluted:
that is, if you see something convoluted there is a good chance the
reason why is compatibility.
Halil Pasic (10):
s390x: add helper get_machine_class
s390x: add css_migration_enabled to machine class
s390x/css: add vmstate entities for css
s390x/css: add vmstate macro for CcwDevice
virtio-ccw: add vmstate entities for VirtioCcwDevice
virtio-ccw: use vmstate way for config migration
s390x/css: remove unused subch_dev_(load|save)
s390x/css: add ORB to SubchDev
s390x/css: turn on channel subsystem migration
s390x/css: use SubchDev.orb
