Description
Official port linux-cachyos-bore and linux-cachyos-bore-eevdf for Fedora
linux-cachyos-bore-eevdf 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-bore uses as default the BORE scheduler
- BORE - (Burst-Oriented Response Enhancer) CPU Scheduler by firelzrd (BORE)
Announcement (20.08.2023): Due to the large amount of work on the LTO kernel, its further development will be discontinued. Instead, we provide a kernel with a BORE + CFS and BORE + EEVDF scheduler. Please make appropriate changes to the system in order to receive updates. Sorry for the difficulties.

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.
