Re: [Patch 1/2] MdeModulePkg PeiCore: Reset PeimNeedingDispatch when its security violation

["Zeng, Star" <star.zeng@intel.com>]

Reviewed-by: Star Zeng <star.zeng@intel.com> to this change.

How about to also move the code blocks below into the "if (Status != EFI_SECURITY_VIOLATION) {" to follow PI Spec?

                PERF_START (PeimFileHandle, "PEIM", NULL, 0);
                REPORT_STATUS_CODE_WITH_EXTENDED_DATA (
                  EFI_PROGRESS_CODE,
                  (EFI_SOFTWARE_PEI_CORE | EFI_SW_PC_INIT_BEGIN),
                  (VOID *)(&PeimFileHandle),
                  sizeof (PeimFileHandle)
                  );

                REPORT_STATUS_CODE_WITH_EXTENDED_DATA (
                  EFI_PROGRESS_CODE,
                  (EFI_SOFTWARE_PEI_CORE | EFI_SW_PC_INIT_END),
                  (VOID *)(&PeimFileHandle),
                  sizeof (PeimFileHandle)
                  );
                PERF_END (PeimFileHandle, "PEIM", NULL, 0);

PI Spec:
EFI_SW_PC_INIT_BEGIN
Initializing software module by using StartImage() or an equivalent PEI service.


Thanks,

When PEIM is security violation, its matched extraction ppi may not be installed. So, its PeimNeedingDispatch will still reset to TRUE.
