The VFIO platform device gets connected to the platform bus
on a machine init done notifier. Only at that point irqfd can be
setup. An irq connect notifier would be helpful to do that job.
Instead of adding a new callback at sysbus or qdev level, this
series proposes to use the property check() callback (credit to
Paolo).
- the callback is passed to qdev_init_gpio_out_named
- sysbus class now holds a irq_set_hook method usable as check
callback
- sysbus_init_irq initializes the callback to the class method
- object_set_link_property is modified so that
* the target object is populated before the check
* check takes an Object ** enabling to access the object
container.
Then The VFIO platform device would override the irq_set_hook
method in a separate patch.
Please let me know if those modifications are acceptable. Else
I will follow Peter's proposal.
Best Regards
Eric

qdev: pass the check callback to qdev_init_gpio_out_named
qdev: check callback takes Object **target as third argument
sysbus: add irq_set_hook
