The zPCI driver needs to get specific information from the host
IOMMU.
In this patch, the IOMMU DMA start and end usable addresses are
retrieved using the VFIO_IOMMU_GET_INFO iotcl by introducing
capabilities to the vfio_iommu_type1_info structure.

Pierre Morel (2):
vfio:iommu: Use capabilities do report IOMMU informations
vfio:iommu: Get DMA information from real IOMMU
