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

[Amit Shah <amit.shah@redhat.com>]

Hello people,

This iteration of the series removes the START and END flags (and
hence the header associated with each buffer). That's the major change
since the last submission.

Please review.

Obligatory disclaimer:
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.

The older virtio-console.c file is completely removed and a new
virtio-serial.c is introduced so that reviewing is easier. I can send a
later patch to rename virtio-serial.c back to virtio-console.c.

Amit Shah (8):
  virtio: Remove duplicate macro definition for max. virtqueues, bump
    up the max
  virtio-console: qdev conversion, new virtio-serial-bus
  virtio-serial-bus: Maintain guest and host port open/close state
  virtio-serial-bus: Add a port 'name' property for port discovery in
    guests
  virtio-serial-bus: Add support for buffering guest output, throttling
    guests
  virtio-serial-bus: Add ability to hot-unplug ports
  virtio-serial: Add a 'virtserialport' device for generic serial port
    support
  Move virtio-serial to Makefile.objs
