[PATCH v6 17/18] vfio/type1: Check MSI remapping at irq domain level

2017-01-05 Thread Eric Auger
In case the IOMMU translates MSI transactions (typical case on ARM), we check MSI remapping capability at IRQ domain level. Otherwise it is checked at IOMMU level. At this stage the arm-smmu-(v3) still advertise the IOMMU_CAP_INTR_REMAP capability at IOMMU level. This will be removed in subsequent
