...> pointer dereference and panic at boot: I think that's because patch 01/14 move the fwspec access too early. In err = pci_for_each_dma_alias(to_pci_dev(dev), iort_pci_iommu_init, &info); if (!err && iort_pci_rc_supports_ats(node)) dev->iommu_fwspec->flags |= IOMMU_FWSPEC_PCI_RC_ATS; the iommu_fwspec is only valid if iort_pci_iommu_init() initialized it successfully, if err == 0. The following might fix it: diff --git a/drivers/acpi/arm64/iort.c b/drivers/acpi/arm64/iort.c index 0e981d7...

Hi, here is a patch-set to rename iommu_param to dev_iommu and establish it as a struct for generic per-device iommu-data. Also move the iommu_fwspec pointer from struct device into dev_iommu to have less iommu-related pointers in struct device. The bigger part of this patch-set moves the iommu_priv pointer from struct iommu_fwspec to dev_iommu, making is usable for iommu-drivers which do not
