DXE SMM Ready To Lock protocol as defined in the PI 1.2 specification.
DXE SMM Ready To Lock protocol introduced in the PI 1.2 specification.
This UEFI protocol indicates that SMM is about to be locked.
This protocol is a mandatory protocol published by a DXE driver prior to invoking the
EFI_SMM_ACCESS2_PROTOCOL.Lock() function to lock SMM.
According to PI 1.4a specification, this UEFI protocol indicates that
resources and services that should not be used by the third party code
are about to be locked.
This protocol is a mandatory protocol published by PI platform code.
This protocol in tandem with the End of DXE Event facilitates transition
of the platform from the environment where all of the components are
under the authority of the platform manufacturer to the environment where
third party extensible modules such as UEFI drivers and UEFI applications
are executed. 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.
