Description
LIQUORIX KERNEL
※ Upstream GitHub repo
Liquorix is a distro kernel replacement built using the best configuration and kernel sources for desktop, multimedia, and gaming workloads.
Major Features
- Zen Interactive Tuning: Tunes the kernel for responsiveness at the cost of throughput and power usage.
--- Virtual Memory Subsystem ---------------------------
Mem dirty before bg writeback..: 10 % -> 20 %
Mem dirty before sync writeback: 20 % -> 50 %
--- Block Layer ----------------------------------------
Default MQ scheduler......: mq-deadline -> bfq
--- CPU Scheduler (CFS) --------------------------------
Scheduling latency.............: 6 -> 3 ms
Minimal granularity............: 0.75 -> 0.3 ms
Wakeup granularity.............: 1 -> 0.5 ms
CPU migration cost.............: 0.5 -> 0.25 ms
Bandwidth slice size...........: 5 -> 3 ms
--- CPU Scheduler (MuQSS) ------------------------------
Scheduling interval............: 6 -> 4 ms
ISO task max realtime use......: 70 % -> 25 %
- MuQSS Process Scheduler: Fair process scheduler for gaming, multimedia, and real-time loads.
- High Resolution Scheduling: High resolution timeouts and 1000Hz tick rate for precise low jitter task scheduling.
- Preemptible tree-based hierarchical RCU: RCU implementation for real-time systems.
- Hard Kernel Preemption: Most aggresive kernel preemption before requiring real-time patches. Guarantees responsive system under high intensity mixed workload scenarios.
- Budget Fair Queue: Proper disk scheduler optimized for desktop usage, high throughput / low latency.
- TCP BBR2 Congestion Control: Fast congestion control, maximizes throughput, guaranteeing higher speeds than Cubic.
- WineSync/NTSync module available: Fast, kernel-backed syncing support driver module for Wine for faster performance. (Copr exclusive)
- Distribution Kernel Drop-in Replacement: Proper distribution style configuration supporting broadest selection of hardware. Paravirtualization options enabled to reduce overhead under virtualization.
- Minimal Debugging: Minimum number of debug options enabled to increase kernel throughput.
- Binary Builds For Fedora® and Enterprise Linux*: Binary builds are produced on Copr for EPEL 8, CentOS 8 and 9 Stream, and Fedora® Linux 33, 34, 35, and Rawhide
*) Liquorix kernel is NOT based on RHCK and thus may break bug-for-bug compatibility with RHEL (for instance, kmod
packages from ELRepo will NOT work, and akmod
packages from RPMFusion may not be compatible with the kernel-devel
of Liquorix kernel). You should not run this software on a machine that requires compatibility with RHEL.
to support the previous package maintainer (donations to upstream can be given here)
Installation Instructions
Fedora® Linux, EPEL 8-compatible distros, and CentOS 9 Stream:
sudo dnf copr enable jplie/kernel-lqx
sudo dnf in kernel-lqx
Also kernel-lqx-devel and kernel-lqx-headers required if planning to build kernel modules (e.g. nvidia proprietary driver)
sudo dnf in kernel-lqx-devel kernel-lqx-headers
Optionally, you may sign the kernel image and modules for secure boot. Follow the instructions here
