Performance Library 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.
