This is mostly for readability of the code. Let's make it clear which callers can create an implicit monitor when the chardev is muxed. This will also enforce a safer behaviour, as we don't really support creating monitor anywhere/anytime at the moment. Add an assert() to make sure the programmer explicitely wanted that behaviour. There are documented cases, such as: -serial/-parallel/-virtioconsole and to less extent -debugcon. Less obvious and questionable ones are -gdb, SLIRP -guestfwd and Xen console. Add a FIXME note for those, but keep the support for now. Other qemu_chr_new() callers either have a fixed parameter/filename string or do not need it, such as -qtest: * qtest.c: qtest_init() Afaik, only used by tests/libqtest.c, without mux. I don't think we support it outside of qemu testing: drop support for implicit mux monitor (qemu_chr_new() call: no implicit mux now). * hw/ All with literal @filename argument that doesn't enable mux monitor. * tests/ All with @filename argument that doesn't enable mux monitor. On a related note, the list of monitor creation places: - the chardev creators listed above: all from command line (except perhaps Xen console?) - -gdb & hmp gdbserver will create a "GDB monitor command" chardev that is wired to an HMP monitor. - -mon command line option From this short study, I would like to think that a monitor may only be created in the main thread today, though I remain skeptical :) Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Markus Armbruster <armbru@redhat.com>
