@sj now moves on to another area, memory management: how to handle more data with less memory with DAMOS.

#kr2026

The season for conferences is back. I will travel for three weeks, starting from tomorrow. During the trip, I will give four talks in three conferences.

Next week, I will be in Paris for Kernel Recipes. I will have a talk [1] introducing DAMOS. After the conference, I will head to Prague for LPC and OSSummit Europe.

After enjoying Prague for a week, I will have two talks in LPC. One [2] for updates of DAMON work for memory tiering and general NUMA management at Special Purpose Memory Management Micro-Conference, Monday. And another one [3] for the beyond-page table accessed bit DAMON extension community collaboration project at DAMON (Nano) Conference, Tuesday.

Finally, I will share [4] how DAMON could be effectively used in Open Source Summit Europe, Wednesday.

Looking forward to meeting people in Paris and Prague. If you find me, please feel free to come and shake my hand in person!

Today I found Sashiko [1] now has a "login" button.

Five years ago today, DAMON was merged [1] into the mainline. It was grateful years. I learned things much more than I expected in the five years. Hopefully DAMON gave some fun and wins to people. I'm looking forward to the next five years.

Deliveries are on the track. We start the milestone 2 of DAMON extension beyond the page table accessed bit for AMD IBS-like h/w features and per-CPUs-like detailed monitoring. Milestone 1 is considered to be delivered on time. Milestone 2 will take time, but seems still doable by the planned timeline.

Linux 7.3-rc1 is released. Hence DAMON newsletter [1] for the cycle is also published.

TL; DR:

Just after breaking the record of DAMON history in the last cycle, this cycle
again broke the record. It was the busiest cycle of DAMON history. 20 authors
made 161 commits and 2283 lines of changes for DAMON on the Linux mainline. A
new data attributes monitoring feature, a few optimizations for DAMON users,
and quite a lot of refactoring are delivered. New DAMON usages and development
projects are shared. The first DAMON (nano) Conference is scheduled.

Jason Angelov developed an interesting project, "Cold Pages DAMON Pager". It utilizes DAMON to find cold pages and than compress those.

Some talks just write themselves, @KernelRecipes is going to be fun this year!

(not that it's not fun every year, but you get the idea...)

The complete schedule of the first DAMON (nano) Conference is now available [1] at the web page. Looking forward to meet you all in Prague!

RE: https://social.kernel.org/objects/bcd257a9-c3c5-4e75-bda7-a06d6681aefd

Ten years. That's how long it's been since Jonathan Corbet last gave his famous Kernel Report at Kernel Recipes (https://archives.kernel-recipes.org/document/the-kernel-report/) and two years since the talk appeared on the schedule at all.

He'll be opening the conference with it.

In Jonathan's own words, the session covers "what is happening in the kernel community and where it might go."

Not registered yet? Hurry! Only a handful of seats left, especially for the full three days.

The schedule: https://kernel-recipes.org/en/2026/schedule/

LPC 2026 is sold out! If you haven't secured your ticket yet, please refer to our latest blog post for information about the wait list.

We buried my father today. He will be missed, but he was 94 years old and had a good run, holding his bit of sky for many decades. And how many can say that?

An extended obituary may be found here:

Today I learned yet another approach to use AI and a maintainer to compare something that they don't understand against their own solution. Creative, and disappointing to be honest. Sigh.

We will have the first DAMON (nano) Conference at LPC'26. The call for proposals [1] is just published. Looking forward to your submission and meet in Prague!

Meet the 2026 Kernel Recipes mascot.

Curious, optimistic, and very much in tune with the world around it.

This year, our little penguin is thinking beyond code. From sustainability to responsible tech, it reflects values that have always been close to the open source community.

With the devastating wildfires affecting France this summer, it also reminds us that technology doesn't exist in a vacuum. The challenges we face are shared—and so is the responsibility to build a better future.

I will present how to use DAMON in a right way with known wrong usages at Open Source Summit Europe in Prague. If DAMON disappointed you before, this will hopefully help you better understanding it.

@KernelRecipes I'm honored this year again, to have a session [1] at Kernel Recipes. Last year I introduced [2] how we can monitor data accesses. This year I will introduce how you can make kernel to self-drive the information for saving memory.

Registrations for Kernel Recipes 2026 are OPEN! Join us September 21-23 for three days of deep-dive kernel talks, great conversations with fellow kernel folks, and way too much coffee

This year's godfather: @corbet, who's put incredible work into shaping this year's agenda. Huge thanks, Jon.
