Framework SMM Status Code Protocol on PI SMM Status Code Protocol Thunk.
|
||
|
|
|
||
|
|
This thunk driver locates PI SMM Status Code Protocol in the SMM protocol database and
|
||
|
|
installs it in the UEFI protocol database.
|
||
|
|
|
||
|
|
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.
