Athena OS

Kernel

Athena OS offers several kernels that could be set after the installation.

By default, Athena OS adopts the LTS Kernel because it is one of the officially supported kernels and it is characterized to be stable and to have low-latency computing.

The list of available kernels the user can be installed is the following:

  • Linux Kernel: Vanilla Linux kernel and modules, with a few patches applied
  • Linux LTS Kernel: Long-term support (LTS) Linux kernel and modules
  • Linux Hardened Kernel: A security-focused Linux kernel applying a set of hardening patches to mitigate kernel and userspace exploits
  • Linux Realtime Kernel: All of the kernel is preempted, with the exception of a few very small regions of code (‘raw_spinlock critical regions’)
  • Linux Realtime LTS Kernel: Long-term support (LTS) Linux realtime kernel and modules
  • Linux Zen Kernel: Result of a collaborative effort of kernel hackers to provide the best Linux kernel possible for everyday systems
  • Linux Liquorix Kernel: Kernel replacement built using Debian-targeted configuration and the Zen kernel sources. Designed for desktop, multimedia, and gaming workloads
  • Linux XanMod Kernel: Aiming to take full advantage in high-performance workstations, gaming desktops, media centers and others and built to provide a more rock-solid, responsive and smooth desktop experience

In Athena Arch, they can be installed by pacman.

In Athena Nix, they can be set by editing /etc/nixos/modules/hardware/kernel/default.nix. Use Nix Search to get the correct name of the kernel package name to implement.
