Supported Architectures

• zen
• zen2
• zen3
• tigerlake
• skylake
• haswell
• alderlake

About Liquorix

• Zen Interactive Tuning: Tunes the kernel for responsiveness at the cost of throughput and power usage.
• PDS Process Scheduler: Fair process scheduler for gaming, multimedia, and real-time loads.
• High Resolution Scheduling: 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 BBR2 Congestion Control: Fast congestion control, maximizes throughput, guaranteeing higher speeds than Cubic.
• Compressed Swap: Swap storage is compressed with LZ4 using zswap
• Multigenerational LRU: Alternative LRU algorithm that performs better under high memory pressure and uptimes
• 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.

In addition:

• WineSync: Winesync is yet another reimplementation of the NT synchronization primitives for Wine. Uses the Xanmod patch.
