MITIGABLE_DEVICE_INTERFACE structure (pcivirt.h)

  • Article

Stores function pointers to callback functions implemented by the physical function (PF) driver for the mitigable device interface.

Syntax

typedef struct _MITIGABLE_DEVICE_INTERFACE {
  USHORT                         Size;
  USHORT                         Version;
  PVOID                          Context;
  PINTERFACE_REFERENCE           InterfaceReference;
  PINTERFACE_REFERENCE           InterfaceDereference;
  PREAD_WRITE_MITIGATED_REGISTER ReadWriteMitigatedRegister;
} MITIGABLE_DEVICE_INTERFACE, MITIGABLE_DEVICE_INTERFACE;

Version

Version of this structure

Context

Driver-defined context passed by the driver.

InterfaceReference

Pointer to a routine that increments the number of references to this interface. For more information about this routine, see InterfaceReference.

InterfaceDereference

Pointer to a routine that decrements the number of references to this interface. For more information about this routine, see InterfaceDereference.

ReadWriteMitigatedRegister

Pointer to the driver's implementation of the READ_WRITE_MITIGATED_REGISTER callback function.

Remarks

This callback function is implemented by the physical function (PF) driver. This function reads and writes mitigated address spaces, in the form required by GUID_MITIGABLE_DEVICE_INTERFACE.

The PF driver registers its implementation by setting the ReadVfConfig member of the SRIOV_DEVICE_INTERFACE_STANDARD, configuring a WDF_QUERY_INTERFACE_CONFIG structure, and calling WdfDeviceAddQueryInterface.
