> Add a tracepoint for DAMOS_QUOTA_NODE_ELIGIBLE_MEM_BP quota goal > evaluation. The tracepoint fires once per quota-score computation when > the goal metric is DAMOS_QUOTA_NODE_ELIGIBLE_MEM_BP, exposing > context_idx, scheme_idx, nid, target_value, and current_value. > current_value is reported as the quota tuning sees it, after the goal's > complement setting is applied. > > The DAMOS_QUOTA_NODE_ELIGIBLE_MEM_BP metric expresses node memory > occupancy as basis points of eligible bytes. This information is not > exposed through any existing external interface (perf stat, /proc, or > sysfs), so the tracepoint is the only way for userspace to observe the > target and current eligible-memory basis point values at quota-scoring > time. > > Link: > https://lore.kernel.org/linux-mm/[email protected]/ > Signed-off-by: Ravi Jonnalagadda <[email protected]>
