Liquorix Kernel

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 aggressive 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 BBR Congestion Control: Fast congestion control, maximizes throughput, guaranteeing higher speeds than Cubic.
  • Binary Builds For Popular Debian Distros: Binary builds are produced for Debian Stable, Testing, and Unstable. Ubuntu builds are available on the Liquorix PPA same day within hours of Debian releases going up.
  • 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.
Install

Debian Prerequisites:

curl 'https://liquorix.net/add-liquorix-repo.sh' | sudo bash

Ubuntu Prerequisites:

sudo add-apt-repository ppa:damentz/liquorix && sudo apt-get update
