Installation Guide¶
You'll need to install perf in your system. perf uses CPU performance counters( Performance Monitoring Counters or PMCs).
1) Install Required Packages like libelf-dev libdw-dev binutils-dev
libaudit-dev by using the following command
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
2) Download the Source code for perf-tools v6.3 using the following command
git clone https://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools-next.git/
3) Install perf. perf command is available in packages linux-tools-common, linux-intel-iotg-tools-common, etc. Hence, install any of these.
4) Run make command to build the project
- 4.1) It may show an error since the config file is not set and has to be changed. Run the following command.
make xconfig
- 4.2) 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
```
- 4.3) Check if qt5 has been installed properly using *qmake --version*
- 4.4) 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
- 4.4) Now, Finally run *make xconfig* and it will work properly.
5) Go to the root directory of the kernel and run perf test. You will see tests
passing, skipping, or failing.
