Description
CURRENTLY TESTING
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.
- 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: Binary builds are produced on Copr for Fedora 32, 33, 34, and Rawhide
Installation Instructions
Fedora:
sudo dnf copr enable rmnscnce/kernel-lqx
sudo dnf in kernel-lqx # Also kernel-lqx-devel and kernel-lqx-headers if needed
