At the moment, the EFI_DXE_SMM_READY_TO_LOCK_PROTOCOL is only installed if S3 is enabled -- at the end of SaveS3BootScript(). While a runtime OS is never booted with SMM unlocked (because the SMM IPL locks down SMM as a last resort: > SMM IPL! DXE SMM Ready To Lock Protocol not installed before Ready To > Boot signal > SmmInstallProtocolInterface: [EfiSmmReadyToLockProtocol] 0 > Patch page table start ... > Patch page table done! > SMM IPL locked SMRAM window ), we shouldn't allow UEFI drivers and applications either to mess with SMM just because S3 is disabled. So install EFI_DXE_SMM_READY_TO_LOCK_PROTOCOL in PlatformBdsInit() unconditionally.
