Description

If you prefer immutable systems you can use Bazzite which shares many kernel patches

If you are interested in a more complete out of the box experience, I recommend trying out Nobara

kernel-blu

What is this?

kernel-blu is a custom fedora kernel based Fedora's always ready kernel It aims to support more hardware, improve existing functionality and give end-users access to cutting-edge features.

Its based on the old kernel-fsync kernel.

What does it contain?

kernel-blu contains quite a few additions:

• amdgpu radeon patch
• amdgpu HDR support
• Bore CPU Scheduler
• i915 async page flipping fixes
• i915 real-time capabiltiies
• uinput overrides
• amd pstate improvements
• BBR3
• miscellaneous additions
  • usb interrupt interval override
  • Fixing DualShock bluetooth poll rate to 1ms

[patch] used to be included, why was it removed?

patches are added based on recommendations from contributors and users but often they are for specific hardware that I do not have to test. If a patch becomes too cubersome to maintain it may be removed until its made clear that there are people relying on it, feel free to open an issue on [Github]https://github.com/Jan200101/kernel-blu) if this is the case.

Can you add more patches?

I'm always open to patch recommendations, feel free to open an issue on the [Github repo]https://github.com/Jan200101/kernel-blu). I am but a single person, so I don't always have the necessary means to test or verify some patches, let alone make judgement calls if some patches are sane to include so in general only things that are optional or bring no major downside are included.

Can you port it to other distros?

kernel-blu is based on the Always Ready Kernel, it should be possible to use the kernel tree when building your distros kernel. If you want to port the additions to a different kernel a helpful repo with patches is provided here.

Here is a non comprehensive list of patches that used to be included but were removed and why:

• linux-surface: Not updated for 6.14, will be readded at a later date
• asus-linux: unmaintainable
• steam deck: multiple different patches, unclear which to pick
• acs-override: enables sandbox escapes through IOMMU

Made possible thanks to:

• Fedora Project
• Nobara Project
• Bazzite
• CachyOS
• Frogging Family
• every patch author
• and everyone who helped along the way

Installation Instructions

Fedora

dnf copr enable sentry/kernel-blu

dnf update --refresh

If you don't want any official Fedora kernels and only use this blu one
edit /etc/yum.repos.d/fedora-updates.repo and add

exclude=kernel*

to the bottom of the [updates] section

Fedora Silverblue

⚠️⚠️⚠️ Support for Silverblue and its flavors is minimal. If these instructions stop working you may need to figure out how to do this yourself ⚠️⚠️⚠️

Silverblue has no official support for copr, so some manual work is involved, its recommended to use Bazzite instead

sudo wget https://copr.fedorainfracloud.org/coprs/sentry/kernel-blu/repo/fedora-<version>/sentry-kernel-blu-fedora-<version>.repo -O /etc/yum.repos.d/kernel-fsync.repo

sudo rpm-ostree override replace --experimental --freeze --from repo='copr:copr.fedorainfracloud.org:sentry:kernel-fsync' kernel kernel-core kernel-modules kernel-modules-core kernel-modules-extra
