...wing things happen? 1) some vDPA device driver probe the hardware and call vdpa_request_irq() in its PCI probe function. 2) vDPA device is probed by vhost-vDPA Then irq bypass can't work since we when vdpa_unsetup_irq() is called, there's no driver bound. Or is there a requirement that vdap_request/free_irq() must be called somewhere (e.g in the set_status bus operations)? If yes, we need document those requirements. Thanks
