Steven Barrett has released Liquorix Linux Kernel 7.2-5, the third incremental update in just over thirty-six hours, which enhances the Project-C scheduler optimizations to reduce Linux wake latency. The update aims to keep coupled tasks on SMT sibling threads and prioritize placing synchronized wakeups on the waker's core, benefiting Linux gamers and audio producers. The new patches focus on maintaining L2 cache locality by preventing the disruption of task pairs during load redistribution and optimizing the handling of thread wakeups. While the Liquorix kernel caters primarily to AMD64 users and aims for improved interactivity, it may not be suitable for everyone, particularly those with heavy compute tasks
Liquorix Linux Kernel 7.2-5 Shipped: Project-C SMT Optimizations Cut Microseconds Off Linux Wake Latency
Steven Barrett shipped Liquorix Linux Kernel 7.2-5 today, the third incremental update in under thirty-six hours. The release focuses on Project-C scheduler optimizations that keep coupled tasks on SMT sibling threads and prioritize placing sync wakees on the waker's core before looking at idle CPUs. It's a niche but highly relevant update for Linux gamers and audio producers chasing lower wake latency, though the project remains AMD64-only and lacks official support for ARM hardware.
