Hi SJ,
We discussed this earlier.
- Are there plans to make DAMON monitor/manage cgroup instead of individual pids?
Thanks, Badari

Hi all,
DAMON has merged into mainline as a data access monitoring tool that equips a best-effort overhead-accuracy tradeoff mechanism, and then extended for data access-aware system operations. I'd like to briefly introduce current state of DAMON and share/discuss about 2023 plans including below.
- Finer and easier-to-use DAMOS tuning - tuning aggressiveness based on user or kernel feed (e.g., QPS or PSI) - Merging DAMON user space tool into the mainline - Extending DAMON - Page-granularity monitoring - LRU-lists based page-granulariy monitoring - CPU-specific access monitoring - Read/Write-only access monitoring - More DAMON-based Operation Schemes - Tiered memory management - THP memory footprint reduction - NUMA balancing
I hope to hear concerns/interests about the plans for prioritizing each work items and get some suggestions of future works and collaboration with other kernel subsystems/hackers.
Thanks, SJ
