_PCI_MSIX_TABLE_CONFIG_INTERFACE structure

Description

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.

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.
