[Qemu-devel] [PATCH v14 09/10] sysbus: add irq_routing_notifier |
Date: |
Wed, 29 Apr 2015 15:52:06 +0100 |
Add a new connect_irq_notifier notifier in the SysBusDeviceClass. This
notifier, if populated, is called after sysbus_connect_irq.
This mechanism is used to setup VFIO signaling once VFIO platform
devices get attached to their platform bus, on a machine init done
notifier.
Signed-off-by: Eric Auger <address@hidden>

v2 -> v3:
- rename irq_routing_notifier into connect_irq_notifier
v1 -> v2:
- duly put the notifier in the class and not in the device
