Linux kernel 7.2 released with cache-aware scheduling and AI-assisted fixes
Key points
- Linux kernel 7.2 released by Linus Torvalds.
- Introduces Cache Aware Scheduling to optimize CPU cache usage.
- Includes fixes for AI-discovered security vulnerabilities.
- Improvements benefit complex CPU-cache layouts and storage-intensive workloads.
Linux Kernel 7.2 Release
Linus Torvalds announced the release of Linux kernel 7.2. This release incorporates several updates, including a significant change to scheduling and numerous fixes, many of which were identified through the use of AI tools.
Cache-Aware Scheduling
A key addition in kernel 7.2 is Cache Aware Scheduling. This new program aggregates tasks sharing data to the same LLC cache domain, which reduces cache bouncing and cache misses. The previous scheduler balanced load across CPU cores without considering shared memory, leading to inefficiencies as threads on different cores would repeatedly fetch the same data. This update aims to improve data access efficiency, particularly for systems with complex CPU-cache layouts, newer graphics and mobile hardware, and storage-intensive workloads.
Users will likely see these features in fall Linux distributions, such as Ubuntu 26.10.
AI in Development and Fixes
The kernel 7.2 release also includes many fixes attributed to AI tools. These AI-assisted changes are primarily patches for security vulnerabilities discovered by AI, rather than new features written by AI. Torvalds noted that while AI tools are useful for identifying bugs, the process of handling AI-detected bugs should be streamlined to avoid unnecessary work.
