Provides services to log the SMI handler registration.
|
|
|
|
This API provides services for the SMM Child Dispatch Protocols provider,
|
|
to register SMI handler information to SmmCore.
|
|
|
|
NOTE:
|
|
There is no need to update the consumers of SMST->SmiHandlerRegister() or
|
|
the consumers of SMM Child Dispatch Protocols.
|
|
The SmmCore (who produces SMST) should have ability to register such
|
|
information directly.
|
|
The SmmChildDispatcher (who produces SMM Child Dispatch Protocols) should
|
|
be responsible to call the services to register information to SMM Core.
