Module iort 

IORT (IO Remapping Table) types for aarch64 PCIe topology.

Structs

Iort

IortIdMapping

IortItsGroup

ITS Group node. Followed by its_count u32 ITS identifiers.

IortMemoryAccessProperties

IortNodeHeader

IortPciRootComplex

IortRmr

RMR node header. Followed by rmr_count IortRmrDescriptor entries, then mapping_count IortIdMapping entries.

IortRmrDescriptor

RMR memory range descriptor.

IortSmmuV3

SMMUv3 node per IORT spec DEN0049E §E.4.

Constants

IORT_NODE_TYPE_RMR

IORT_NODE_TYPE_SMMUV3

IORT_PCI_ROOT_COMPLEX_REVISION

IORT_REVISION

IORT_RMR_ACCESS_PRIVILEGE

RMR flags: access privilege hint. When set, the OS may map the region with elevated privileges (e.g., supervisor mode).

IORT_RMR_REMAP_PERMITTED

RMR flags: remap permitted. When clear, the region MUST be identity- mapped (IOVA == physical address).

IORT_RMR_REVISION

IORT_SMMUV3_FLAG_COHACC

SMMUv3 node flags.

IORT_SMMUV3_FLAG_DEVICEID_VALID

device_id_mapping_index is valid (IORT rev E.e / node rev 5+).

IORT_SMMUV3_MODEL_GENERIC

SMMUv3 model: generic SMMU-v3.

IORT_SMMUV3_REVISION
