The protocol is published immediately after signaling of the + End of DXE Event. PI modules that need to lock or protect their resources + in anticipation of the invocation of 3rd party extensible modules should + register for notification on installation of this protocol and effect the + appropriate protections in their notification handlers. For example, PI + platform code may choose to use notification handler to lock SMM by invoking + EFI_SMM_ACCESS2_PROTOCOL.Lock() function. + + Copyright (c) 2009 - 2017, Intel Corporation.
