DMA_IOMMU_INTERFACE_V1 structure (wdm.h)

  • Article

A structure containing the set of IOMMU Version 1 (V1) functions.

Syntax

typedef struct _DMA_IOMMU_INTERFACE_V1 {
  PIOMMU_DOMAIN_CREATE              CreateDomain;
  PIOMMU_DOMAIN_DELETE              DeleteDomain;
  PIOMMU_DOMAIN_ATTACH_DEVICE       AttachDevice;
  PIOMMU_DOMAIN_DETACH_DEVICE       DetachDevice;
  PIOMMU_FLUSH_DOMAIN               FlushDomain;
  PIOMMU_FLUSH_DOMAIN_VA_LIST       FlushDomainByVaList;
  PIOMMU_QUERY_INPUT_MAPPINGS       QueryInputMappings;
  PIOMMU_MAP_LOGICAL_RANGE          MapLogicalRange;
  PIOMMU_UNMAP_LOGICAL_RANGE        UnmapLogicalRange;
  PIOMMU_MAP_IDENTITY_RANGE         MapIdentityRange;
  PIOMMU_UNMAP_IDENTITY_RANGE       UnmapIdentityRange;
  PIOMMU_SET_DEVICE_FAULT_REPORTING SetDeviceFaultReporting;
  PIOMMU_DOMAIN_CONFIGURE           ConfigureDomain;
} DMA_IOMMU_INTERFACE_V1, *PDMA_IOMMU_INTERFACE_V1;

Members

CreateDomain

A pointer to the IOMMU_DOMAIN_CREATE function that creates a DMA remapping device domain.

DeleteDomain

A pointer to the IOMMU_DOMAIN_DELETE function that deletes a device domain.

AttachDevice

A pointer to the IOMMU_DOMAIN_ATTACH_DEVICE function that attaches a device to a domain.

DetachDevice

A pointer to the IOMMU_DOMAIN_ATTACH_DEVICE function that detaches a device from a domain.

FlushDomain

A pointer to the IOMMU_FLUSH_DOMAIN function that flushes the TLB for all entries which match this domain.

FlushDomainByVaList

A pointer to the IOMMU_FLUSH_DOMAIN_VA_LIST function that flushes the TLB for all entries that match the specified domain's ASID and one of the addresses in the provided list.

QueryInputMappings

A pointer to the IOMMU_QUERY_INPUT_MAPPINGS function that attempts to find input mapping IDs which are valid for the given device and populate the provided buffer with those IDs.

MapLogicalRange

A pointer to the IOMMU_MAP_LOGICAL_RANGE function that maps a range of pages into the address space of the specified domain.

UnmapLogicalRange

A pointer to the IOMMU_UNMAP_LOGICAL_RANGE function that unmaps a range of pages.

MapIdentityRange

A pointer to the IOMMU_MAP_IDENTITY_RANGE function that creates an identity mapping for the provided MDL in the specified domain.

UnmapIdentityRange

A pointer to the IOMMU_UNMAP_IDENTITY_RANGE function that deletes an identity mapping.

SetDeviceFaultReporting

A pointer to the IOMMU_SET_DEVICE_FAULT_REPORTING function that sets the device fault reporting state to device already attached to a domain.

ConfigureDomain

A pointer to the IOMMU_DOMAIN_CONFIGURE function that configures a domain for use.

Remarks

These function pointers are the same as those provided by the deprecated DMA_IOMMU_INTERFACE structure. For V1 functions, use the DMA_IOMMU_INTERFACE_EX structure over the deprecated one.
