In this function do you see iommu_domain getting allocated or initialized?
As per the name of function arm_smmu iommu_domain_init.
Where is init of iommu_domain in this function?

+static int arm_smmu_iommu_domain_init(struct domain *d)
+{
+       struct arm_smmu_xen_domain *xen_domain;
+
+       xen_domain = xzalloc(struct arm_smmu_xen_domain);
+       if (!xen_domain)
+               return -ENOMEM;
+
+       spin_lock_init(&xen_domain->lock);
+       INIT_LIST_HEAD(&xen_domain->contexts);
+
+       dom_iommu(d)->arch.priv = xen_domain;
+
+       return 0;
+}
