- PI SMM Status Code Protocol on Framework SMM Status Code Protocol Thunk.
-
- This thunk driver produces PI SMM Status Code Protocol and SMM Report Status Code Handler Protocol.
- And it registers a status code handler within itself to route status codes into Framework SMM Status
- Code Protocol.
-
- Note that Framework SMM Status Code Protocol and PI SMM Status Code Protocol have identical protocol
- GUID and interface structure, but they are in different handle databases.
