[Qemu-devel] [RFC PATCH 0/8] virtio-console: Move to qdev, multiple devices, generic ports

[Amit Shah]

Hello,

This series splits up the patches by functionality. Note, however,
that patches 2-6 introduce some functionality that's advertised to the
guest as having to work all at once or not at all. Also, the savevm
version is bumped only once but save/restore state is added in each of
the patches. They are split only for easier reviewability.

There are a few differences from yesterday's posting: comments from
Markus have been addressed and also some issues that were pending have
been resolved.

There's still a couple of fixmes:
- The vl.c bits aren't right yet (need to accomodate s390).
- Locking isn't perfect, a few extra locks are needed, but it doesn't
  matter as long as qemu doesn't run it all separately (I've tested
  with the kvm tree with -smp 2 as well and it runs fine).
