The Liquorix Linux Kernel has been updated to version 7.1-21, featuring fixes for the PDS scheduler that improve task management. This release is part of the broader Project-C overhaul, which has been focused on optimizing various scheduling and performance aspects since mid-2026. The kernel is tailored specifically for AMD64 architectures and has seen enhancements in security measures, including the default use of AppArmor and the integration of two CVEs. Users can install the new kernel easily with a one-liner script, but it is primarily designed for those needing low-latency performance for gaming or audio tasks
Liquorix Linux Kernel 7.1-21 Released With PDS Scheduler Fixes and Ongoing Project-C Overhaul
Steven Barrett's Liquorix Kernel just landed at 7.1-21, shipping two targeted patches that cap and properly drain the PDS scheduler's boost credit to stop unfair task hoarding. The release sits alongside a massive, ongoing Project-C rewrite that's been optimizing cache alignment, SMT awareness, and lock contention since mid-2026. It's an aggressive daily release cycle for a strictly AMD64-only package, but the work keeps the custom scheduler sharp for gaming and low-latency audio workloads. Security also got a facelift with AppArmor as default, Landlock enabled, and two CVEs backported into the mix.
