But there's a small problem. Today getfd commands are closely tied to the
Monitor. In Anthony's development tree, the getfd commands are tied to the
new QMP server's session support.

Asking you to integrate the new QMP server only to have the getfd command
returning a simple integer would be too much, but at the same time I think
you'll have to at least to break it from the monitor. This means moving its
data structure away from the Monitor object and probably reworking the
internal API used to get fds (ie. monitor_get_fd()).

Shouldn't be hard, but you should be careful not to break external users.

Just to verify, are you talking about moving the "fds" off the Monitor
struct?  -->  QLIST_HEAD(,mon_fd_t) fds;


Was this already moved away from the Monitor struct in Anthony's
development tree?  If not do you have a recommendation on where to move it?

Yes, iirc it moved inside the new QMP server session support in Anthony's tree.

I think this would make more sense to me if I took a look at the getfd
code in Anthony's development tree.  Is this the correct tree?  I had
some issues cloning it.  https://github.com/aliguori/qemu-next.git

The 'development' tree I'm referring to is the old glib branch in

Hmm, it looks like fds is still on the Monitor struct in that branch. I'll do some more searching later unless you have anything else you can point me to.
