[Qemu-devel] [PATCH 00/41] virtio: port to vmstate

[Juan Quintela <quintela@redhat.com>]

Hi

this patch series run on top of my previous vmstate cleanups and fixes.
It ports virtio* and msix at the same time (msix and virtio-pci are too entangled
to do it separately).  It contains:

- Use DO_UPCAST instead of local function for doing the casts
- virtio: add a type field (pci and syborg by now).
- strange pci bindings for virtio are gone (i.e. config and queues are handled
  explicitely for pci, the ones that used them).
- virtio-net: make vlans to use uint8_t instead of uint32_t array, that
  makes it work through big_endian/low endian migrations.  This needs testing
  from people that use the feature.
- virtio-blk: It has no hope for migration between 32/64bits hosts or
  big-endian/little-endian.  It sends a structure with memcpy that contains:
  - target_phys_addr_t (32 or 64 bits depending on host/guest)
  - void *             (again it depends on host)
  - size_t             (it depends on host again)
  I didn't changed it, but we should.
- virtio-blk: change the list of requests to QLIST.  I also needed a
  QLIST_COPY_HEAD to not have to break the abstraction, created it.

Later, Juan.
