Project ID: 103910

Description

Official port linux-cachyos-bore and linux-cachyos-bore-eevdf for Fedora

CachyOS

Meet CachyOS team!

linux-cachyos uses as default the BORE-EEVDF scheduler

  • BORE - (Burst-Oriented Response Enhancer) CPU Scheduler by firelzrd (BORE)
  • EEVDF - (Earliest Eligiable Virtual Deadline) First EEVDF is a replacement for the CFS Scheduler from Peter Zijlstra

linux-cachyos-lts uses as default the BORE scheduler

  • BORE - (Burst-Oriented Response Enhancer) CPU Scheduler by firelzrd (BORE)

Announcement (02.11.2023): Due to EEVDF scheduler getting into the upstream kernel we are renaming kernel-cachyos-bore-eevdf to kernel-cachyos and dropping cfs based kernel.

DNF may give you this error when updating: Problem: The operation would result in removing the following protected packages: kernel-cachyos-bore-eevdf-core, to get around this just remove the protected package with sudo rpm -e --nodeps --allmatches protected package name update the system and then reboot

Checking for the cpu support

Check support by the following the command

/lib64/ld-linux-x86-64.so.2 --help | grep "(supported, searched)"

If it does not detect x86_64_v3 support do not install the kernel. Otherwise you will end up with a non-functioning operating system!

SElinux and cachyos kernel

sudo setsebool -P domain_kernel_load_modules on

If you are using SElinux. Enable the above policy to load kernel modules.

Installation Instructions

FEDORA WORKSTATION

sudo dnf copr enable bieszczaders/kernel-cachyos

sudo dnf install kernel-cachyos

OR for realtime kernel

sudo dnf install kernel-cachyos-bore-rt

OR for LTS kernel

sudo dnf install kernel-cachyos-lts

LTS kernel works with x86_64v2 cpu's and legacy nvidia drivers

FEDORA SILVERBLUE

Do not use on Fedora Silverblue 39 installation will fail

cd /etc/yum.repos.d/

sudo wget https://copr.fedorainfracloud.org/coprs/bieszczaders/kernel-cachyos/repo/fedora-$(rpm -E %fedora)/bieszczaders-kernel-cachyos-fedora-$(rpm -E %fedora).repo

sudo rpm-ostree override remove kernel kernel-core kernel-modules kernel-modules-core kernel-modules-extra --install kernel-cachyos

sudo systemctl reboot

OR for realtime kernel

sudo rpm-ostree override remove kernel kernel-core kernel-modules kernel-modules-core kernel-modules-extra --install kernel-cachyos-rt

sudo systemctl reboot

OR for LTS kernel

sudo rpm-ostree override remove kernel kernel-core kernel-modules kernel-modules-core kernel-modules-extra --install kernel-cachyos-lts

sudo systemctl reboot

LTS kernel works with x86_64v2 cpu's and legacy nvidia drivers

OPTIONAL (HIGHLY RECOMMENDED) FOR BETTER PERFORMANCE

Install UKSMD.
