[Qemu-devel] Re: [PATCH 5/5] virtio-console: Throttle virtio-serial-bus if we can't consume any more guest data

  Hi,

+/* Callback function when the timer expires */
+static void unthrottle_port(VirtConsole *vcon)
+{

Why a timer?

qemu_set_fd_handler(fd, NULL, write_callback, opaque) ?

cheers,
  Gerd
