💖 intel_read_rawclk(9) — Kernel API Manual 💖

okay bestie, welcome to intel_read_rawclk(9) from the Kernel API Manual — this is the little page that tells you how to find the current RAWCLK frequency, and yes, it’s giving “one job, done slay” energy 💅✨

✨ NAME ✨

intel_read_rawclk — determine the current RAWCLK frequency 🎀

---

🦋 SYNOPSIS 🦋

u32 intel_read_rawclk (struct intel_display *display );

---

🌸 ARGUMENTS 🌸

• display — the display instance, periodt. That’s the whole vibe here 🫶

---

💜 DESCRIPTION 💜

So basically: this determines the current RAWCLK frequency. RAWCLK is a fixed frequency clock, so this only needs to be done once — literally once, bestie, no need to make it a whole recurring thing 😌✨
