Steven Barrett has released a new Liquorix Linux kernel update based on the Linux Kernel 6.7.10 for Debian and Ubuntu.

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    ->   2    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 for precise low jitter task scheduling. Threaded IRQs and RCU to reduce jitter caused by periodic tick at 250hz.
• 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

The Liquorix kernel can be installed by way of meta-packages. This will guarantee that the latest kernel is installed on every upgrade.

64-bit:

sudo apt-get install linux-image-liquorix-amd64 linux-headers-liquorix-amd64

New in 6.7-14

  * merge 6.7.10
  * add optimizations from Project-C v6.8-r1
  * update version to 6.7.10-1
