ps3_enable_pm(9)

💅 NAME 💅

ps3_enable_pm — bestie, this is the one that turns on the entire performance monitoring unit. Like, the whole thing. All of it. Periodt. 👑

---

✨ SYNOPSIS ✨

void ps3_enable_pm (u32 cpu );

That's it. That's the whole call. Short and iconic. 🎀

🫶 ARGUMENTS 🫶

• cpu — okay so, tragic lore: the docs literally just say -- undescribed --. No cap, that's the entire description in the source. So we're not gonna sit here and invent lore for it — it's a u32 cpu and the manpage is staying mysterious about it. iykyk 🙈

---

🌸 DESCRIPTION 🌸

Okay so here's the vibe: when we enable the LPM, all pending writes to counters get committed. That's the whole tea. 🍓

Like — the moment the LPM gets switched on, anything that was still floating around waiting to hit the counters? It lands. Committed. Done. Slay. ✨
