| 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. |
