Official port linux-cachyos-bore and linux-cachyos-lts for Fedora Meet CachyOS team! linux-cachyos and linux-cachyos-lts use 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 Announcement (05.05.2024): The Lenovo Legion patchset has been removed from the LTS kernel from version 6.6.30 and will also be removed from the 6.8 kernel in the 6.8.10 release. The reason is, that some users have reported issues with it. There's a chance, we will add them again, if the issues get fixed from upstream. 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 remove the protected package with sudo rpm -e --nodeps --allmatches protected package name update the system and then reboot GCC-compiled kernels The kernels in this repository are compiled with GCC. We have a seperate repo with Clang-compiled LTO kernels, which can be found here. The Clang-compiled kernels give better performance, but may have issues with some kernel modules. Features AMD PSTATE Preferred Core and enabled as default Latest BTRFS and XFS improvements & fixes. Latest & improved ZSTD 1.5.5 patch-set. UserKSM daemon from pf. Improved BFQ Scheduler. Back-ported patches from linux-next. BBRv3 tcp_congestion_control. Scheduler patches from linux-next/tip. General improved sysctl settings and upstream scheduler fixes. OpenRGB and ACS Override support. HDR Patches for AMD GPU's and gamescope. Default support for Steam Deck. GitHub copr-linux-cachyos. 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 default kernel. Otherwise you will end up with a non-functioning operating system! If it detects only x86_64_v2, you can use the LTS kernel. 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.
