When do the tests for the WB Performance Profiler , it reports that there are samples are dropped when target is booted up with many activated CPUs, for example above around 32 cores.
Run the "profiledemo_linux.out" example and view it with the "Performance Profiler" tree. It doesn't showed up if the target is booted up with more than 32 activated CPUs (the example target has total of 64 CPUs) and WB indicates there are a lot of sample got dropped.
When the "profiledemo_linux.out" shows up with 32 activated CPUs, there is no sample dropped.
