damon_nr_accesses_mvsum(9)

🌸 damon_nr_accesses_mvsum 🌸

okay bestie, welcome to the damon_nr_accesses_mvsum(9) page — this is a kernel API manual situation, and it's literally about access frequency scores, so buckle up 💅

---

✨ NAME ✨

damon_nr_accesses_mvsum — returns the moving sum access frequency score 🎀

---

🦋 SYNOPSIS 🦋

unsigned int damon_nr_accesses_mvsum (struct damon_region *r , struct
damon_ctx *ctx );

like, that's the whole signature, no cap ✨

---

🎀 ARGUMENTS 🎀

• r — the region you want the access frequency of 💖 this is the main character here
• ctx — the DAMON context that r belongs to 🫶

---

👑 DESCRIPTION 👑

okay so here's the vibe: this function tells you for how many sampling iterations in the last aggregation interval — that's damon_attrs->aggr_interval — the region was found to be accessed 🌸

so basically you can read that value as the relative access frequency score of the region (r). iconic 💅

now the important part, don't skip this: the value is calculated as a pseudo moving sum, which means it is not an exact value 😭 it's just a best-effort reasonable estimation. so like, treat it as a really good guess, not gospel, yk?

ngl this is the kind of thing where precision girlies need to chill — it's an estimation and it says so fr fr

---

⭐ RETURN ⭐

the pseudo moving sum access frequency score 🔥 that's it, that's the return value, go off
