I will present and discuss below topics in Kernel Recipes, LPC, and Open Source Summit Europe in following weeks. In Kernel Recipes 26 next week, I will present how DAMON can be turned into Data Access Monitoring-based System Operation Engine. The title of the talk is “DAMOS: The Smart Cruise Control for RAM”. In Linux Plumbers 26 in the week of 2026-10-05, I will have two sessions. In the Device and Specific Purpose Memory Management Micro-conference (Monday), I will present and discuss the DAMON extension project for memory tiering and general NUMA memory management....

I will present and discuss below three topics in Linux Storage/File System/Memory Management/BPF (LSFMMBPF) 2026. DAMON Updates: Tiering, Pagel Level Monitoring and DAMON-X Allowing NUMA hinting faults or alternatives to DAMON Data Access-aware Transparent Hugepages Detailed schedules and links to details of each topic can be found from this Google doc.

As today is the first day of 2026, I checked my open source commits statistics using my simple and buggy scripts. Similar statistics for 2024 is available at another post. Note that the script may have bugs, and numbers don’t tell everything. TL; DR In short, I made 2nd and 1st biggest changes to Linux kernel memory management subsystem among the 321 people, in terms of lines of changes (6,661 / 73,685 lines) and commits (199 / 1,870 commits)....

In the coming second week of December, I will have one and three talks at at Open Source Summit (OSSummit) Japan and Linux Plumbers (LPC), respectively. In the Refereed track of LPC, I will introduce new DAMON features for page level and fleet wide data access monitoring. In the “Linux System Monitoring and Observability” micro conference of LPC, I will share history and limitations on DAMON’s output visualization formats and discuss how we can improve....

I got a Macbook Pro. I was wondering if I can do kernel development on it since I recently learned that modern small computers are fast enough to be used for frequent kernel builds. I also heard a few of my previous colleague kernel developers use their Macbook for kernel builds. Unfortunately I cannot install Linux kernel on the laptop at the moment, though. I hence created a Debian13 VM on it using UTM and ran the kernel compile benchmark....
