| 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. | |
