DXE SMM Ready To Lock protocol introduced in the PI 1.2 specification.
|
|
|
|
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.
