IOMMU_DEVICE_CREATION_CONFIGURATION structure (wdm.h)
IOMMU_DEVICE_CREATION_CONFIGURATION describes a configuration or list of configurations to be used as part of creation and initialization of an IOMMU_DMA_DEVICE.
Syntax
typedef struct _IOMMU_DEVICE_CREATION_CONFIGURATION {
LIST_ENTRY NextConfiguration;
IOMMU_DEVICE_CREATION_CONFIGURATION_TYPE ConfigType;
union {
IOMMU_DEVICE_CREATION_CONFIGURATION_ACPI Acpi;
PVOID DeviceId;
IOMMU_DEVICE_CREATION_CONFIGURATION_PASID Pasid;
};
} IOMMU_DEVICE_CREATION_CONFIGURATION, *PIOMMU_DEVICE_CREATION_CONFIGURATION;
Members
NextConfiguration
Optional list to provide additional configurations.
ConfigType
An enum describing which configuration is represented. See IOMMU_DEVICE_CREATION_CONFIGURATION_TYPE.
Acpi
If (ConfigType == IommuDeviceCreationConfigTypeAcpi), provides the input parameters necessary for device creation. See IOMMU_DEVICE_CREATION_CONFIGURATION_ACPI
DeviceId
Defines the PVOID member DeviceId.
Pasid
Defines the IOMMU_DEVICE_CREATION_CONFIGURATION_PASID member Pasid.
Remarks
If the device is an ACPI device on an ARM64 system, then an IOMMU_DEVICE_CREATION_CONFIGURATION structure must be provided during device creation, ConfigType = IommuDeviceCreationConfigTypeAcpi, and ACPI-specific parameters must be provided through IOMMU_DEVICE_CREATION_CONFIGURATION_ACPI in the Acpi field.
