The GUID_MSIX_TABLE_CONFIG_INTERFACE interface enables device drivers for devices that support MSI-X interrupts to modify the PCI bus hardware MSI-X interrupt table. This interface is available in Windows Vista with Service Pack 1 (SP1), Windows Server 2008, and later operating systems.
To use this interface, send an IRP_MN_QUERY_INTERFACE IRP to your bus driver with InterfaceType = GUID_MSIX_TABLE_CONFIG_INTERFACE. The bus driver supplies a pointer to a PCI_MSIX_TABLE_CONFIG_INTERFACE structure that contains pointers to the individual routines of the interface.
