[Qemu-devel] [PATCH v3 0/9] serial device hotplug patch series. |
Date: |

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 three patches cleanup chardev a bit and 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 file,id=pciserial,path=/root/hotchardev.log
(qemu) device_add pci-serial,id=pciserial,chardev=pciserial
And the reverse:
(qemu) device_del pciserial
(qemu) chardev_del pciserial
New in v2:
- added two chardev cleanup patches.
- switched chardev_{add,del} commands to netdev_{add,del} style.
cheers,
Gerd
