I made a typo on the mail address for linux-mm@, on the original mail. So
forwarding to linux-mm@ as a reply-to-all. Sorry for making noise.

Hello all,
I'm posting my Kernel Summit topic suggestion below. I will also submit it to
the LPC site.
DAMON[1,2] is a Linux kernel subsystem that provides efficient data access
monitoring and access-aware system operations (DAMON-based Operation Schemes,
a.k.a DAMOS). From multiple use cases of it including multiple years of real
world products' usage, it is proven to be useful for improving memory
efficiency.
Like many other Linux kernel projects, DAMON is developed by the community. We
proactively present the status and discuss future plans of DAMON with the
community. As a major part of the effort, we had a DAMON session every year at
Kernel Summit[3-7]. Those sessions have been one of the most essential and
effectful fuels of the project.
This session will continue the sharing and discussion at the kernel summit of
2024. We will share what feedback we received, what patches have been
developed or are under development, what requests are still in the planning
stage, and what the plans are. With that, hopefully we will have discussions
that will be helpful for improving and prioritizing the plans and specific
tasks, and finding new requirements.
Specific sub-topics would include, but are not limited to:
- Fine-grained DAMOS control
- Automated tuning of DAMOS
- Tiered-memory management
- Access/Contiguity-aware Memory Auto-scaling
- Write-only monitoring and live migration
Based on the progress until the summit, some items can be added or dropped.
