MGLRU’s Next Step Is Frequency-Aware Memory Reclaim

A new Linux memory-management RFC proposes frequency-guided promotion for Multi-Gen LRU, aiming to distinguish repeatedly accessed folios before reclaim. The early results are promising, but infrastructure teams should treat it as a benchmark target—not a production feature—until the design stabilizes.

Linux 7.2 Turns DAMON Into a Control Loop for DRAM/CXL Memory

Linux 7.2 expands DAMON from access-pattern observation toward feedback-driven memory placement. New goal metrics, deterministic controls, and data-attribute sampling give infrastructure teams better building blocks for managing DRAM and CXL tiers—but production policy still requires workload-specific validation.

AI Is Making Attacks Faster — But Linux Still Slows Them Down

The cybersecurity landscape has undergone a fundamental transformation as artificial intelligence capabilities become increasingly accessible to both defenders and attackers. While AI-powered automation tools enable threat actors to launch more sophisticated attacks at unprecedented scale and speed,
