Hi Eric, Is there any reason why you are not supporting SMMUv3 driver? Qualcomm hardware doesn't not support SMMUv2 hardware, please add support for SMMUv3 in next patch set. I've ported ' RFC,v3,09/10] iommu/arm-smmu: Implement reserved region get/put callbacks' to SMMUv3 driver and tested

[RFC v3 00/10] KVM PCIe/MSI passthrough on ARM/ARM64 and IOVA reserved regions

Following LPC discussions, we now report reserved regions through iommu-group sysfs reserved_regions attribute file. Reserved regions are populated through the IOMMU get_resv_region callback (former get_dm_regions), now implemented by amd-iommu, intel-iommu and arm-smmu. The intel-iommu reports
