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
