    qxl: add a connector property to denote hotplug should rescan modes. · 4695b039

    So GNOME userspace has an issue with when it rescans for modes on hotplug
    events, if the monitor has no EDID it assumes that nothing has changed on
    EDID as with real hw we'd never have new modes without a new EDID, and they
    kind off rely on the behaviour now, however with virtual GPUs we would
    like to rescan the modes and get a new preferred mode on hotplug events
    to handle dynamic guest resizing (where you resize the host window and the
    guest resizes with it).
    
    This is a simple property we can make userspace watch for to trigger new
    behaviour based on it, and can be used to replaced EDID hacks in virtual
    drivers.
