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

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

Hello,

This series addresses some comments from last time:
- locking is removed
- send/receive struct elements in endian-safe way
- appropriate device is created based on machine being used
  (virtio-serial-pci vs virtio-serial-s390).

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 'virtserialport' device for generic serial port
    support
  Move virtio-serial and virtio-serial-bus to Makefile.hw
