I am currently trying to extract the performance events information from the sabrelite i.mx6q ( )


I have successfully integrated the gator daemon - driver after kernel compiling in order to enable the recording data on the ds5 streamline analyzer (Streamline Performance Analyzer – DS-5 Development Studio – ARM Developer ).


The ARM energy probe is connected. on the DS-5 GUI after a test record, I can see the percentage of the CPU activity, the clock frequency/cycles and also othe informations (please see the attached figure). But the problem that is there are any information from the available events related to the cores-events or to the cache-events. all the values of these events are zero knowing that the cores execute applications during the records.


I would like to know what is the problem.
