Sorry for making noise. ================================= >8 ======================================== 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.
