Generally speaking, if the path from root port to the PCIe device
is ACS enabled, the iommu will create a single iommu group for this
PCIe device. If all PCIe devices on the path are ACS enabled the
The PCIe ACS capability will affect the layout of iommu groups.
Generally speaking, if the path from root port to the PCIe device
is ACS enabled, the iommu will create a single iommu group for this
PCIe device. If all PCIe devices on the path are ACS enabled then
Linux can determine this path is AC
