*	UefiCpuPkg/SmmCpu: Add PcdSmmApPerfLogEnable control AP perf-logging	Ray Ni	2023-06-21	1	-1/+10
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	When a platform has lots of CPU cores/threads, perf-logging on every AP produces lots of records. When this multiplies with number of SMIs during post, the records are even more. So, this patch adds a new PCD PcdSmmApPerfLogEnable (default TRUE) to allow platform to turn off perf-logging on APs.

*	UefiCpuPkg/CpuSmm: Add perf-logging for MP procedures	Ray Ni	2023-06-21	1	-0/+90
	MP procedures are those procedures that run in every CPU thread. The EDKII perf infra is not MP safe so it doesn't support to be called from those MP procedures. The patch adds SMM MP perf-logging support in SmmMpPerf.c. The following procedures are perf-logged: * SmmInitHandler * SmmCpuFeaturesRendezvousEntry * PlatformValidSmi * SmmCpuFeaturesRendezvousExit Signed-off-by: Ray Ni <ray.ni@intel.com> Cc: Eric Dong <eric.dong@intel.com> Cc: Rahul Kumar <rahul1.kumar@intel.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: Jiaxin Wu <jiaxin.wu@intel.com> Reviewed-by: Jiaxin Wu <jiaxin.wu@intel.com> Reviewed-by: Eric Dong <eric.dong@intel.com>
