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....
A few weeks ago I heard modern normal computers can build kernel faster than I expected. My 10 years old personal laptop (Thinkpad X1) used to build a kernel per a couple of hours. The last time I built kernel on the laptop was about 8 years ago. Since then, I was always using only workstation or server level machines for building kernels. So I wanted to know how good modern normal desktop-level machines are, by myself....
