📰 AI Helped Uncover A "50-80x Improvement" For Linux's IO_uring
Linux block maintainer and IO_uring lead developer Jens Axboe recently was debugging some slowdowns in the AHCI/SCSI code with IO_uring usage. When turning to Claude AI to help in sorting through the issue, patches were devised that can deliver up to a "literally yield a 50-80x improvement on the io_uring side for idle systems." The code is on its way to the Linux kernel...

SUSE may be for sale, again
据路透社报道,私募股权公司 EQT 正考虑出售其持有的开源企业软件公司 SUSE。目前 EQT 已聘请投资银行 Arma Partners 接触潜在买家,但相关讨论尚处早期阶段,交易能否达成尚不确定。
SUSE 近年来几经易手:2018 年被 EQT 收购,2021 年在法兰克福证券交易所上市,随后又在 2023 年 8 月被 EQT 再次私有化。

WhisperTux
Simple #voice#dictation application for #Linux. Uses whisper.cpp for offline speech-to-text transcription. No fancy GPUs are required although whisper.cpp is capable of using them if available. Once your speech is transcribed, it is sent to a ydotool daemon that will write the text into the focused application.
Features
Local speech-to-text processing via whisper.cpp (no cloud dependencies)
No expensive hardware required (works well on a plain x86 laptop with AVX instructions)
Global keyboard shortcuts for system-wide operation
Automatic text injection into focused applications
Configurable whisper models and shortcuts

[$] Development tools: Sashiko, b4 review, and API specification
Linux 内核项目在开发工具方面采取了独特的方法,避免使用许多不适合其社区规模和协作方式的常用开发系统。也可以说,内核项目过去在工具上的投入不足,有时似乎倾向于用更困难的方式做事。然而,最近为内核开发工具投入的努力有所增加,并取得了一些有趣的成果。该领域的最新进展包括 Sashiko 代码审查系统、集成到 b4 工具中的补丁审查管理器,以及一个用于规范和验证内核 API 的新框架尝试。

📰 The Intel Lunar Lake CPU Performance Gains On Linux Over The Past Year
Recently I ran benchmarks looking at the Xe2 graphics performance gains on Intel Lunar Lake over the past year with what's shipped by Ubuntu and comparing against our original tests of the Lenovo ThinkPad X1 Carbon Gen 13 Aura Edition. With those Lunar Lake iGPU benchmarks out of the way, here is a look at how the Lunar Lake CPU performance has evolved on Linux since April 2025.

[$] BPF comes to io_uring at last
Linux 内核的异步 I/O 接口 io_uring 通过两个共享环形缓冲区与用户空间通信:提交队列用于发送请求,完成队列则存放结果。尽管共享内存减少了大量开销,但内核仍需切换至用户空间以处理完成事件并提交后续工作,这仍会产生开销。
Pavel Begunkov 提交的补丁集旨在最小化这一开销。它允许开发者使用 BPF 程序扩展 io_uring 的事件循环,使程序能直接响应完成事件并提交后续工作项,无需切换至用户空间。该补丁集已开发很长时间,现已被内核社区接受。
这一改进将进一步提升 io_uring 的高性能 I/O 处理能力。
