Liquorix kernel 7.2-14 ships Project-C scheduler tweak for loaded systems
When every core is busy, it now tells coupled threads to take turns.
Steven Barrett has released Liquorix Linux Kernel 7.2-14. The headline change is small, really just one line of code, but it targets one of the most annoying cases in scheduling: a fully loaded multithreaded system where no core has spare cycles to give.
The release was tagged October 1, 2026, based on upstream Linux 7.2.8. Liquorix isn't something you install by accident. It's a patched kernel built on top of the Zen kernel, layered with its own configuration and performance patches, then packaged as a drop-in "distribution kernel" for Debian, Ubuntu, and Arch Linux. Most distros ship a general-purpose kernel tuned to serve everyone well enough. Liquorix wants to serve you particularly well if you game, do audio or video production, or just notice your desktop feeling jittery under load.
The "take turns" tweak
Let me explain the vocabulary plainly. In Liquorix's alternative scheduler, a waker is the thread that wakes another thread up, and the wakee is the one getting roused. These two often need to run close together, because the wakee is frequently doing exactly the work the waker has been waiting for.
Here's the problem. If you pin both tasks onto the same physical core, specifically onto a hyperthreaded pair called an SMT sibling, they end up time-sharing one core. Both can starve each other of execution. That's the opposite of keeping them coupled, which is the entire point of Project-C.
The obvious fix is to spread the two tasks across separate physical cores. That's ideal. It's also impossible when every core is already occupied. That's the case 7.2-14 addresses.
The scheduler now coordinates the pair so they alternate across available cores instead of grinding against each other on a single slot. Same idea, different words from the changelog: "Let a stacked wake pair take turns when no CPU is idle."
The end result should be lower latency and smoother frame times under heavy, fully loaded workloads, which is exactly what the target audience cares about. It's arguably competing with what you'd get from simply disabling hyperthreading, but without forcing you to give up cores outright.
As usual, Liquorix is installable via the one-line curl-to-bash script:
curl -s 'https://liquorix.net/install-liquorix.sh' | sudo bash
