I meant can the following 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...
