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.
