📝 Fedora - koji kernel regression testing
📅 | ⏰ 4 minutes
I will show how to get latest kernel from Koji for testing purpose. For your infomation, Koji build packages take times to appear on updates-testing repository.
The faster way to get latest kernel the is manually download from Koji. As example here, on this blog post I will show how I will load kernel kernel-5.10.4-200 to my Fedora 33 Workstation.
Firstly check the latest success build kernel here
For example, I will use this build

How to install latest kernel from koji?
To grab all the rpms, I will use this command:

It will download almost 12 files (162mb) to my current directory

Nice, now let prepare the test using tool that provided
$ sudo dnf install gcc git python3-fedora make libtirpc libtirpc-devel policycoreutils-python-utils
$ git clone https://pagure.io/kernel-tests.git
$ sudo semanage boolean -m --on selinuxuser_execheap #Allow testsuite to make their heap memory executable
$ cd kernel-tests
$ cp config.example .config
$ vi .config # add your FAS username
Are you ready? Let execute the test
$ sudo ./runtests.sh
$ sudo ./runtests.sh -t performance
After you done, revert SELINUX heap memory executable permission
$ sudo semanage boolean -m --off selinuxuser_execheap
How to revert changes?
reboot your workstation and choose previous kernel from grub menu.

You can reboot to check but at this point the kernel we install from koji are already removed from our system succesfully.
