/**
After e492dc5a267e "pci: Eliminate pci_find_primary_bus()" we don't have an easy mean to retrieve the primary bus of a machine. This will be needed by virtio-iommu-device which is bound to be dynamically instantiated in at least ARM virt and Q35 machines. Adding a get_primary_pci_bus() callback allows to retrieve the PCIBus the iommu is connected to. Signed-off-by: Eric Auger <eric.auger@redhat.com> --- This is a temporary solution until we decide whether the virtio-iommu-device should be instantiable through a -device command line or through a machine command line, as already suggested by Peter (for vsmmuv3 though). --- include/hw/boards.h | 3 +++ 1 file changed, 3 insertions(+)
