class BusDeviceInterface
Defined at line 23 of file ../../src/devices/bus/drivers/pci/bus_device_interface.h
This interface allows for bridges/devices to communicate with the top level
Bus object to add and remove themselves from the device list of their
particular bus instance, obtain their BTIs, and make MSI allocations. This
becomes more important as multiple bus instances with differing segment
groups become a reality.
