Subject: [PATCH v1 0/2] Get DMA information from real IOMMU

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
