Thanks for your replay. I have registered now. This patch addresses the issue for PCIe devices that have multiple PFs within the same IOMMU group, a situation arising from the absence of ACS support. If we want to use these PFs in vDPA, we have to know if the group has been bound to a container by other PF upon each probe.
