PCI_MSIX_TABLE_CONFIG_INTERFACE structure (wdm.h)
The PCI_MSIX_TABLE_CONFIG_INTERFACE structure enables device drivers to modify their MSI-X interrupt settings. This structure describes the GUID_MSIX_TABLE_CONFIG_INTERFACE interface.
Syntax
typedef struct _PCI_MSIX_TABLE_CONFIG_INTERFACE {
USHORT Size;
USHORT Version;
PVOID Context;
PINTERFACE_REFERENCE InterfaceReference;
PINTERFACE_DEREFERENCE InterfaceDereference;
PPCI_MSIX_SET_ENTRY SetTableEntry;
PPCI_MSIX_MASKUNMASK_ENTRY MaskTableEntry;
PPCI_MSIX_MASKUNMASK_ENTRY UnmaskTableEntry;
PPCI_MSIX_GET_ENTRY GetTableEntry;
PPCI_MSIX_GET_TABLE_SIZE GetTableSize;
} PCI_MSIX_TABLE_CONFIG_INTERFACE, *PPCI_MSIX_TABLE_CONFIG_INTERFACE;
Members
Size
The size, in bytes, of this structure.
Version
The driver-defined interface version.
Context
A pointer to interface-specific context information.
InterfaceReference
A pointer to an InterfaceReference routine that increments the interface's reference count.
InterfaceDereference
A pointer to an InterfaceDereference routine that decrements the interface's reference count.
SetTableEntry
A pointer to the interface's SetTableEntry routine.
MaskTableEntry
A pointer to the interface's MaskTableEntry routine.
UnmaskTableEntry
A pointer to the interface's UnmaskTableEntry routine.
GetTableEntry
Reserved for future use.
GetTableSize
Reserved for future use.
Remarks
A driver obtains a pointer to the PCI_MSIX_TABLE_CONFIG_INTERFACE structure by sending an IRP_MN_QUERY_INTERFACE IRP to its bus driver with InterfaceType set to GUID_MSIX_TABLE_CONFIG_INTERFACE.
