Hi,
This version merges the changes requested during the v7 review, remarks from
ppc64 dump support review (yes, we talked about virtio there) and the work on
virtio subsections migration. Also two new patches have been added:
- patch #1 is a preliminary fix for virtio-serial posted by Alexander Graf
- patch #9 prepares the work on the virtio_is_big_endian() helper
The most significant changes are:
- introduction of a new CPU method for virtio
- endianness is taken from CPU that resets the device
- fastpath virtio memory accessors for fixed endian targets
- VMState based virtio subsections (compatibility friendly)
You'll find more detailed changelog in each patch.
Please comment and hopefully apply.
Thanks !
