  This interface conveys performance information out of the Security (SEC) phase into PEI.\r

  This service is published by the SEC phase. The SEC phase handoff has an optional\r
  EFI_PEI_PPI_DESCRIPTOR list as its final argument when control is passed from SEC into the\r
  PEI Foundation. As such, if the platform supports collecting performance data in SEC,\r
  this information is encapsulated into the data structure abstracted by this service.\r
  This information is collected for the boot-strap processor (BSP) on IA-32.\r
