[$] Sub-schedulers for sched_ext 可扩展调度类（sched_ext）允许安装由 BPF 程序构建的自定义 CPU 调度器。它被合并到 6.12 内核版本中，使内核摆脱了此前“一个调度器适应所有场景”的模式；现在任何系统都可以拥有针对其工作负载优化的专属调度器。然而，在单个机器内部，目前仍然是“一个调度器适应所有场景”：整个系统只能加载一个调度器。Tejun Heo 提出的 sched_ext 子调度器补丁系列旨在改变这一状况，允许在单个系统上运行多个 CPU 调度器。 原文链接：https://lwn.net/Articles/1056014/ #Linux#内核#调度器#BPF#sched_ext #AIGC Read more

📰 Linux MAINTAINERS Cleaning For Recently Departed Intel Devs, Altera Drivers Oprhaned The layoffs and restructuring at Intel in 2025 caused unfortunate hits to their Linux/open-source engineering including various driver maintainers leaving and even their CPU temperature driver being orphaned for lack of maintainers. Sent out today were a number of additional updates to the MAINTAINERS file for the Linux kernel to reflect other Intel departures in recent months. 🔗 Source: https://www.phoronix.com/news/Linux-MAINTAINERS-Intel-March #linux#opensource#intel#kernel

📰 IBM Updates Linux Patches For Introducing ARM64 KVM Virtualization On s390 At the start of April was the peculiar announcement of IBM collaborating with Arm on "dual architecture" hardware. The initial fruits of that collaboration at least are Linux kernel patches for enabling ARM64 virtualization acceleration on IBM Z servers. As we approach the end of the month, IBM has now posted a second iteration of those patches for enabling AArch64 software to run on IBM s390 via the Kernel-based Virtual Machine (KVM)... 🔗 Source: https://www.phoronix.com/news/ARM64-On-s390-IBM-Z-v2 #arm#kernel#linux
