-  This interface conveys performance information out of the Security (SEC) phase into PEI.
-
-  This service is published by the SEC phase. The SEC phase handoff has an optional
-  EFI_PEI_PPI_DESCRIPTOR list as its final argument when control is passed from SEC into the
-  PEI Foundation. As such, if the platform supports collecting performance data in SEC,
-  this information is encapsulated into the data structure abstracted by this service.
-  This information is collected for the boot-strap processor (BSP) on IA-32.
-
-  @param[in]  PeiServices  The pointer to the PEI Services Table.
-  @param[in]  This         The pointer to this instance of the PEI_SEC_PERFORMANCE_PPI.
-  @param[out] Performance  The pointer to performance data collected in SEC phase.
-
-  @retval EFI_SUCCESS      The performance data was successfully returned.
