Because SMM perf-logging is migrated to non-SMRAM at ReadyToBoot by DxeCorePerformanceLib, the perf-logging after ExitBS is useless and impact the SMI latency at runtime. Hence the SmmPerformanceLib is updated to disable perf-logging after ExitBS.

# Performance library instance used in SMM phase.
|
|
#
|
|
# This library instance provides infrastructure for SMM drivers to log performance
|
|
# data. It consumes SMM PerformanceEx or Performance Protocol published by SmmCorePerformanceLib
|
|
# to log performance data. If both SMM PerformanceEx and Performance Protocol are not available,
|
|
# it does not log any performance information.
