An extended version of the INTERFACE structure that allows device drivers to invoke the callback functions that perform device domain operations.
[!CAUTION]
DMA_IOMMU_INTERFACEhas been deprecated in Windows 10, version 2103 and has been replaced by DMA_IOMMU_INTERFACE_EX.
VersionThe driver-defined interface version.
CreateDomainA pointer to the IOMMU_DOMAIN_CREATE callback function that creates a DMA remapping device domain.
DeleteDomainA pointer to the IOMMU_DOMAIN_DELETE callback function that deletes a device domain.
AttachDeviceA pointer to the IOMMU_DOMAIN_ATTACH_DEVICE callback function that attaches a device to a domain.
DetachDeviceA pointer to the IOMMU_DOMAIN_DETACH_DEVICE callback function that detaches a device from a domain.
ConfigureDomainA pointer to the IOMMU_DOMAIN_CONFIGURE callback function that configures a domain for use.
FlushDomainA pointer to the IOMMU_FLUSH_DOMAIN callback function that flushes the TLB for all entries which match this domain.
FlushDomainByVaListA pointer to the IOMMU_FLUSH_DOMAIN_VA_LIST callback function that flushes the TLB for all entries that match the specified domain's ASID and one of the addresses in the provided list.
QueryInputMappingsA pointer to the IOMMU_QUERY_INPUT_MAPPINGS callback function that attempts to find input mapping IDs which are valid for the given device and populate the provided buffer with those IDs.
MapLogicalRangeA pointer to the IOMMU_MAP_LOGICAL_RANGE callback function that maps a range of pages into the address space of the specified domain.
UnmapLogicalRangeA pointer to the IOMMU_UNMAP_LOGICAL_RANGE callback function that unmaps a range of pages.
MapIdentityRangeA pointer to the IOMMU_MAP_IDENTITY_RANGE callback function that creates an identity mapping for the provided MDL in the specified domain.
UnmapIdentityRangeA pointer to the IOMMU_UNMAP_IDENTITY_RANGE callback function that deletes an identity mapping.
SetDeviceFaultReportingA pointer to the IOMMU_SET_DEVICE_FAULT_REPORTING callback function that sets the device fault reporting state to device already attached to a domain.
