The Linux kernel development cycle is embracing AI-assisted patches, with Linus Torvalds noting AI input is entering the process in a healthier way by aiming for AI patches to arrive in the regular merge window rather than late in stabilization.

The broader patch pipeline now features more AI-assisted contributions while human review remains essential; patches derived from AI are often rewritten before they are merged.

Linux 7.4 marks the first major rollout of AI-assisted kernel development, including code optimization and performance improvements that accelerate development cycles, with Torvalds cited using these tools.

Security and reliability updates address AMD Zen 6 speculative execution mitigations, improved EDAC memory error detection/correction, and strengthened NTFS3 driver security.

There is a substantial backlog of unfixed CVEs in stable branches, illustrated by data on Linux kernel branches and distributions like Debian 13 and Ubuntu 26.04, underscoring the gap between latest fixes and stable releases.

Beyond AI, the merge includes improvements across drivers, filesystems, networking, Rust, BPF, memory management, performance tools, selftests, and Raspberry Pi 10-inch monitor support.

Hardware and performance highlights include AMD PerfOpt for Radeon GPUs aimed at AI/LLM workloads, finalized Ryzen Zen 6 support, default HDMI 2.1 for AMDGPU, basic Apple M4 enablement, Google Tensor G5 and Pixel 10 support, Snapdragon X2 PC work, Intel IPU8 for Nova Lake laptops, and faster kernel build times.

Apple M4 silicon gains basic kernel enablement enabling support for Google Tensor G5 and Pixel 10, with Qualcomm Snapdragon X2 PC platform tweaks and IPU8 support for Intel Nova Lake laptops.

A large portion of Linux 7.4-rc1 changes centers on hardware support and performance, notably AMD GPU work, Ryzen Zen 6, Radeon PerfOpt for AI workloads, and default HDMI 2.1 support for AMDGPU.

Context from earlier releases shows a growing commit count from Linux 6.14 through 7.3, culminating in a notably large 7.3 with 16,267 commits.

Legacy cleanup removes the BFS file system and RTL8723BS Wi‑Fi driver to streamline the kernel and signal modernization.

The initiative invites open-source projects and distributions to backport security fixes, with Trail of Bits’ Patch the Planet program providing a path for help.
