Description

XanMod Kernel

Upstream GitHub

XanMod is a general-purpose Linux kernel distribution with custom settings and new features. Built to provide a stable, responsive and smooth desktop experience.

The real-time version is recommended for critical runtime applications such as Linux gaming eSports, streaming, live productions and ultra-low latency enthusiasts.

Supports all recent 64-bit versions of Fedora® Linux.

※ Note: The current proprietary NVIDIA, VirtualBox, VMware Workstation / Player or some other dkms modules builds may not be fully compatible with RT kernels.
