Installation Guide¶

You'll need to install perf in your system. perf uses CPU performance counters (Performance Monitoring Counters or PMCs).

Install Required Packages like libelf-dev libdw-dev binutils-dev libaudit-dev by using the following command

sh sudo apt-get install build-essential libelf-dev libdw-dev binutils-dev \ libaudit-dev libtraceevent-dev systemtap-sdt-dev libunwind-dev libslang2-dev libperl-dev libzstd-dev libbabeltrace-ctf-dev flex bison
Download the latest perf-tools Source code using the following command

sh git clone https://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools-next.git/
Install perf. perf command is available in packages linux-tools-common, linux-intel-iotg-tools-common, etc. Hence, install any of these.
Run make command to build the project
1. It may show an error since the config file is not set and has to be changed. Run the following command.
  
  sh make xconfig
2. We will also need to install qt5 for this. Install it using sudo apt-get install qtbase5-dev OR sudo apt install qt5* and set the path using
  
  sh export PKG_CONFIG_PATH=/usr/lib/x86_64-linux-gnu/pkgconfig:/usr/share/pkgconfig
3. Check if qt5 has been installed properly using qmake --version
4. You might need to set kernel.perf_event_paranoid = -1 because the perf record command may fail due to restricted access to performance monitoring features on your system.
  
  sh sudo sysctl -w kernel.perf_event_paranoid=-1
  
  Note: this should not be done in production environment
5. Now, Finally run make xconfig and it will work properly.
Go to the root directory of the kernel and run perf test. You will see tests passing, skipping, or failing.
