Current DAMON_RECALIM is not compatible with the NUMA memory system. To proactively reclaim memory, DAMON_RECLAIM kernel thread(kdamond) has to wake up before kswapd does reclaim memory. However, the current watermark for proactive reclamation is based on entire system free memory. So, though the one memory node is fully used, kdamond is not waked up.
These patches clarify watermarks of DAMOS and enable monitoring per NUMA node proactive reclamation on DAMON_RECLAIM.
Jonghyeon Kim (3): mm/damon: Rebase damos watermarks for NUMA systems mm/damon/core: Add damon_start_one() mm/damon/reclaim: Add per NUMA node proactive reclamation by DAMON_RECLAIM.
