 #  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.
