Re: [PATCH v3 4/4] iommufd: Extend IOMMU_GET_HW_INFO to report PASID capability

PASID usage requires PASID support in both device and IOMMU. Since the iommu drivers always enable the PASID capability for the device if it is supported, so it is reasonable to extend the IOMMU_GET_HW_INFO to report the PASID capability to userspace.
