Linux 7.1 Kernel Development Accelerates #
The Linux 7.1 merge window brought substantial changes this week, headlined by aggressive code cleanup and preparation for next-generation hardware.
Major Code Removal: Linus Torvalds merged a significant cleanup removing 138,000 lines of obsolete code, including:
- The entire old ISDN (Integrated Services Digital Network) subsystem
- PCMCIA-era network drivers with no active upstream users
- Legacy input hardware drivers, including decades-old bus mouse support
- Baikal CPU support
This cleanup was notably driven by an influx of AI/LLM-generated bug reports targeting dated code that lacks active maintainers or users—a novel dynamic in kernel development.

- Intel QAT (QuickAssist Technology) Zstd offload support for hardware-accelerated compression
- HDMI 2.1 Fixed Rate Link (FRL) support added to the open-source Nouveau driver for NVIDIA GPUs—a feature notably AMD has struggled to implement due to HDMI Forum restrictions
Performance Improvements:
- HRTIMER (High-Resolution Timer) subsystem overhaul reducing overhead of frequently-armed timers and improving scheduler responsiveness
- Scheduler improvements including proportional newidle balance code benefiting workloads like easyWave and FIO benchmarks
- IO_uring enhancements including custom event loop logic, expanded IOPOLL capabilities, and zero-copy receive updates
- Memory management updates including RAID fixes and T10 PI data integrity improvements
Desktop Environment Progress:
- KDE Plasma 6.7 development brings per-screen virtual desktop support after 20+ years of community requests, Wayland session management protocol support, and improved multi-GPU System Monitor display
