    Description

      https://doc.qt.io/qtcreator/creator-cpu-usage-analyzer.html

      I would like to have as a note or just clarification in some sections

      To performance analyzer correct work needed:

      1. To allow perf events in kernel 
        echo -e "kernel.perf_event_paranoid=-1\nkernel.kptr_restrict=0" | sudo tee /etc/sysctl.d/10-perf.conf
      2. need to be installed for Debian(Ubuntu):
        sudo apt-get install linux-tools-$(uname r) linux-cloud-tools$(uname -r)
      3.  ./Qt/Tools/QtCreator/libexec/qtcreator/perfparser should be presented
      4.  Some info can be found in the application output even if the performance analyzer shows pop-up errors.
