[Qemu-devel] [PATCH v2 0/9] chardevice hotswap
Posted by Anton Nefedov 6 years, 10 months ago
This serie is a v2 of the February submit
http://lists.nongnu.org/archive/html/qemu-devel/2017-02/msg01989.html

The interface is changed as requested and the changes are slightly reworked
and split into separate patches.

========

The patchset adds support of the character device change without
a frontend device removal.
Yet isa-serial and virtio-serial frontends are supported.

The feature can be helpful for e.g. Windows debug allowing to
establish connection to a live VM from VM with WinDbg.

Anton Nefedov (9):
  char: move QemuOpts->ChardevBackend translation to a separate func
  char: add backend hotswap handler
  char: chardevice hotswap
  hmp: add hmp analogue for qmp-chardev-change
  char: forbid direct chardevice access for hotswap devices
  virtio-console: chardev hotswap support
  serial: move TIOCM update to a separate function
  serial: chardev hotswap support
  char: avoid chardevice direct access
