Star, The PERFORMANCE_PROPERTY structure has a field called CpuFreq.
Since there are many different types of timer sources, some not related to the CPU frequencies, should this field name just be Frequency? Also, one of the long standing issues with the DP command is that all the modules that record performance records must use the same instance of the TimerLib so this same frequency counter is used for all performance records. If we are going to make the types of changes you are proposing here, can we also evaluate if we can update the performance records to include the counter frequency information so the DP command can support evaluation of log entries that are generated using different TimerLib instances?
