Yes, DxeSmmPerformance should could be enhanced to support dump PEI/DXE/SMM
performance data altogether.
Thanks,

Hi
I do not think it is good design.
Can we have one library instance to dump PEI/DXE/SMM performance data
altogether?
If so, it will make developer easy to view all perf data in one place.
Thank you

It depends on which PerformanceLib the DP application linked. For example, if
DxePerfrmanceLib(MdeModulePkg\Library\DxePerformanceLib) got linked, it will
try to dump PEI and DXE performance data; and if
DxeSmmPerfrmanceLib(MdeModulePkg\Library\DxeSmmPerformanceLib) got linked, then
SMM performance data expected.
Thanks,
Star

Thanks for the update. Whether current DP application provide timing of all
drivers? Or we need separate application to measure SMM drivers since DP
application is tied to PerformanceLib.

You need to use PiSmmCoreSmmServicesTableLib SmmServicesTableLib instance.

SmmCorePerformaceLib is using SmmServicesTableLib which cannot be used in
SMM_CORE modules(SVN#10183) and leads to build error. SmmCorePerformaceLib
needs to access SmmAllocatePool, SmmInstallProtocolInterface and
SmiHandlerRegister without gSmst - either integrate SmmCorePerformaceLib as
part of PiSmmCore or mark those functions as extern.
