get_level(9)

💅 get_level(9) — the kernel API manual, but make it cute

okay bestie so this is a page from the Kernel API Manual and it's literally about finding the level for a particular frequency. no cap, that's the whole vibe. it's giving "small function, big responsibility" energy and honestly? we love that for it. 🎀

✨ NAME ✨

get_level — find the level for a particular frequency 🌸

like, the whole point of this icon is that it maps a frequency to a level. periodt. 🔥

---

🦋 SYNOPSIS 🦋

unsigned long get_level (struct cpufreq_cooling_device *cpufreq_cdev ,
unsigned int freq );

that's it. that's the whole signature. copy it exactly, don't @ me. 💅

---

💖 ARGUMENTS 💖

• cpufreq_cdev — the cpufreq_cdev for which the property is required. like, this is the device we're asking about, bestie. it has to be that one. 👑
• freq — the frequency. yep. the actual frequency. the thing we're getting the level for. no notes. 🫶

---

⭐ RETURN ⭐

the level corresponding to the frequency. that's the answer, that's the tea, that's the whole point. 💅✨

quick vibe check: the source line points at ./drivers/thermal, and honestly that's where the magic happens. 🧚
