[Qemu-devel] [PULL 0/7] serial device hotplug patch series.

[Gerd Hoffmann <kraxel@redhat.com>]

  Hi,

This patch series tackles serial device hotplug.

The first four patches have been on the list before, they implement
pci-serial devices featuring a hot-pluggable 16550 uart and got some
minor tweaks only.

The next two patches update the usb-serial device.  It will only show up
in the guest when the chardev is open.  You'll see the difference with
socket chardevs:  If you open the chardev (by connecting to the socket)
the device will show up in the guest, on close (disconnect) it will
disappear.

Final patch adds chardev hotplug to the mix, which makes the other
patches alot more useful.  It is the missing bit needed to really
hotplug serial devices:

   (qemu) chardev_add pciserial file /root/hotchardev.log
   (qemu) device_add pci-serial,chardev=pciserial,id=pciserial

And the reverse:

   (qemu) device_del pciserial
   (qemu) chardev_del pciserial

please review & pull,
  Gerd
