Dear @Peter\_Pertril, May I know what you want to measure in an application? Is nsight is not sufficient for your usecase? ---

I want to use perf top/list or related method to monitor my application hotpoint or bottleneck. Then we do more optimized as needed. In other words, we want to do more application performance analyses with the help of perf tools. ---

Dear @Peter_Pertrili, It seems the apt packages are not available for target. Could you check building from source on target? have you checked it? ---
