[Qemu-devel] [PATCH 0/5] for spice post load char device hook

[Alon Levy]

This reworks my former patch (http://patchwork.ozlabs.org/patch/227678/ - sorry
Hans, can't find the version you posted) per Gerd's suggestion. Specifically it
adds a new qemu_chr_fe_post_load api that is called by the front end and
implemented by the backend. virtio-console implements it, adding it's own hook
which is called by virtio-serial-bus upon post_load from the timer, so that
qemu_chr_fe_post_load is called when the vm is already in the running state.
This makes the spice-qemu-char usage very simple by not requiring yet another
timer.

Alon Levy (5):
  char: add a post_load callback
  merge to char.h
  virtio-serial: add a post_load callback implemented by port
  virtio-console: implement post_load to call to qemu_chr_fe_post_load
  spice-qemu-char: register interface on post load
