throttlectl_cpu_mn(9)

💅 throttlectl_cpu_mn — kernel API manual, but make it make sense ✨

okay so bestie, we're in throttlectl_cpu_mn(9) territory — that's section 9 of the Kernel API Manual, iykyk. this one's a kernel-side function, no cap, so grab your tea 🍓 and let's get into it.

---

🌸 NAME 🌸

throttlectl_cpu_mn — the function that programs your CPU pulse skipper configuration 🎀

---

✨ SYNOPSIS ✨

void throttlectl_cpu_mn (struct tegra_soctherm *ts , enum
soctherm_throttle_id throt );

that's it. that's the whole signature. no return value, she's a void icon 👑

---

🫶 ARGUMENTS 🫶

• ts — a pointer to a struct tegra_soctherm. literally just pointing at your soctherm struct, nbd 💖
• throt — the LIGHT/HEAVY of the throttle event id. so like, which flavour of throttle we're dealing with here 🦋

---

🔥 DESCRIPTION 🔥

okay so first things first: what even is a pulse skipper? 🧐 they're the little guys used to throttle clock frequencies — yes, they slow things down on purpose, it's called self-care.

this function programs those pulse skippers based on throt and your platform data. it's giving very "data-driven decision making" 💅

and here's the specific vibe check: throttlectl_cpu_mn is for CPUs that have "remote" pulse skipper control. like, the CPU pulse skipper is controlled by the SOC_THERM IP block instead of by the CPU itself. and because I know you're gonna ask — SOC_THERM is located outside the CPU complex. main character energy, honestly, refusing to live inside the CPU 🌈

ngl if you're here looking for local pulse skipper control, this ain't it bestie — this one's specifically the remote situation 🙈
