2 | DXE SMM Ready To Lock protocol introduced in the PI 1.2 specification.\r |
| 3 | \r | |
| 4 | According to PI 1.4a specification, this UEFI protocol indicates that\r | |
| 5 | resources and services that should not be used by the third party code\r | |
| 6 | are about to be locked.\r | |
| 7 | This protocol is a mandatory protocol published by PI platform code.\r | |
| 8 | This protocol in tandem with the End of DXE Event facilitates transition\r | |
| 9 | of the platform from the environment where all of the components are\r | |
| 10 | under the authority of the platform manufacturer to the environment where\r | |
| 11 | third party extensible modules such as UEFI drivers and UEFI applications\r | |
| 12 | are executed. The protocol is published immediately after signaling of the\r | |
| 13 | End of DXE Event. PI modules that need to lock or protect their resources\r | |
| 14 | in anticipation of the invocation of 3rd party extensible modules should\r | |
| 15 | register for notification on installation of this protocol and effect the\r | |
| 16 | appropriate protections in their notification handlers. For example, PI\r | |
| 17 | platform code may choose to use notification handler to lock SMM by invoking\r | |
| 18 | EFI_SMM_ACCESS2_PROTOCOL.Lock() function.\r | |
