+    DispatchFunction      - Pointer to dispatch function to be invoked for
+                            this SMI source
+    DispatchContext       - Pointer to the dispatch function's context.

+                            function which Software SMI input value the
+                            dispatch function should be invoked for.
+    DispatchHandle        - Handle of dispatch function, for when interfacing
+                            with the parent Sx state SMM driver.
+
+  Returns:
+    EFI_SUCCESS           - The dispatch function has been successfully
+                            registered and the SMI source has been enabled.
+    EFI_DEVICE_ERROR      - The SW driver was unable to enable the SMI source.
+    EFI_OUT_OF_RESOURCES  - Not enough memory (system or SMM) to manage this
+                            child.
+    EFI_INVALID_PARAMETER - DispatchContext is invalid. The SW SMI input value
+                            is not within valid range.
