    monitor: new parameter "x-oob" · be933ffc
    Peter Xu authored
    Add new parameter to optionally enable Out-Of-Band for a QMP server.
    
    An example command line:
    
      ./qemu-system-x86_64 -chardev stdio,id=char0 \
                           -mon chardev=char0,mode=control,x-oob=on
    
    By default, Out-Of-Band is off.
    
    It is not allowed if either MUX or non-QMP is detected, since
    Out-Of-Band is currently only for QMP, and non-MUX chardev backends.
    
    Note that the client STILL has to request 'oob' during qmp_capabilities;
    in part because the x-oob command line option may disappear in the
    future if we decide the capabilities negotiation is sufficient.
