inttf-kernel - Clear Linux kernel for Fedora 36 users
Table of Contents
This is a project I’ve been working on lately. Build Clear Linux kernel for Fedora users. All Clear Linux patches and almost full kernel config are working currently. Only minor changes to get modprobe, hostname, fbdev, etc. working on Fedora. This is currently still at testing stage and not recommend on any production environment(s). Also remember backup all important data!
I have run several tests mainly using Phoronix Test Suite to see if there is any speed difference between original Fedora kernel and Clear Linux kernel on Fedora. And yes, there are differences. Of course hardware support might be more limited than original Fedora kernel and SELINUX is disabled totally. All tests have been performed SELINUX disabled to see real speed difference. I will publish later comparison video.
If you are looking Intel optimized kernel for Fedora Desktop PC or laptop, then this might be for you.
Check video version of guide, howto install inttf-kernel on Fedora:
Support inttf:
It’s also good to note that I have also another Fedora 36 kernel build, which only disable simpledrm and re-enable fbdev to help NVIDIA users. It’s easy to recognise from file names (Fedora 6xx and Clear Linux 7xx):
inttf – Clear Linux kernels | inttf – Fedora kernels |
---|---|
kernel-5.17.6-703.inttf.fc36.x86_64.rpm | kernel-5.17.6-601.inttf.fc36.x86_64.rpm |
kernel-5.17.9-705.inttf.fc36.x86_64.rpm | kernel-5.17.8-602.inttf.fc36.x86_64.rpm |
Download inttf kernel src.rpm(s).
Howto Install⌗
1. Change root user⌗
su -
## OR ##
sudo -i
2. Disable kernel updates from [fedora] and [updates] repos⌗
Edit /etc/yum.repos.d/fedora.repo file. Add exclude=kernel*
[fedora]
name=Fedora $releasever - $basearch
...
exclude=kernel*
Edit /etc/yum.repos.d/fedora-updates.repo file. Add exclude=kernel*
[updates]
name=Fedora $releasever - $basearch
...
exclude=kernel*
3. Allow some extra kernels to be installed⌗
Edit /etc/dnf/dnf.conf file. Change installonly_limit=x, example:
[main]
gpgcheck=1
installonly_limit=8
...
4. Disable SELinux⌗
You can enable this later, if you want it back.
4.1 Edit /etc/default/grub⌗
Append ‘selinux=0’ to end of ‘GRUB_CMDLINE_LINUX=”…”‘. Example:
GRUB_CMDLINE_LINUX="rhgb quiet rd.driver.blacklist=nouveau nvidia-drm.modeset=1 selinux=0"
4.2 Update grub2 conf⌗
grub2-mkconfig -o /boot/grub2/grub.cfg
5. Enable inttf kernel repo⌗
wget -O /etc/yum.repos.d/inttf-kernel.repo https://rpms.if-not-true-then-false.com/inttf-kernel.repo
Note: if you have inttf.repo active, this is different repo and should work normally together, but if needed you can also disable inttf.repo (kernel updates).
6. Install inttf-kernel packages⌗
Normally dnf update works
dnf update

Is this ok [y/N]
Sometimes you might have newer kernel installed already, because this follows Clear Linux kernel release cycle. If you can’t see 7xx inttf kernel on installing section, then try following command (yes, it’s a one-liner):
dnf install --skip-broken $(for i in $(dnf repoquery --installed kernel\* --qf '%{name}'); do echo $i-$(dnf --quiet --disablerepo=* --enablerepo=inttf-kernel repoquery --queryformat '%{version}-%{release}' kernel |tail -1); done)
7. Reboot⌗
reboot
Latest installed kernel should be selected automatically. You can always boot using another kernel or reinstall needed kernel(s).
8. Problems?⌗
If you have any problems, then drop a comment here or Youtube.
