💅 intel_cdclk_uninit_hw(9) — from the Kernel API Manual, bestie ✨

Okay so real talk, this is a page about <pink>intel_cdclk_uninit_hw</pink> from the Kernel API Manual, and it is short — like, shockingly short — but every crumb of it matters, so let's go 🫶

---

✨ NAME ✨

intel_cdclk_uninit_hw — basically uninitialize CDCLK hardware 💫 that's the whole vibe check, no cap.

---

🦋 SYNOPSIS 🦋

void intel_cdclk_uninit_hw (struct intel_display *display );

That's it. That's the signature. She's clean, she's void, she takes exactly one thing. Periodt 💅

---

🎀 ARGUMENTS 🎀

• display — the display instance 🖥️ like, the actual display we're talking about here. That's the one. That's the whole parameter list, bestie — she's low-maintenance.

---

🌸 DESCRIPTION 🌸

So what does she do? She uninitializes CDCLK. Iconic behaviour, honestly 👑

This is done only during the display core uninitialization sequence. Only then. Not whenever you feel like it, not "just to be safe" — during the display core uninit sequence. That's the moment. That's her moment. 🦋

Okay this is where the page really eats — the whole friend group shows up:

Like, intel_cdclk_init_hw(9) is literally her sister function — one initializes, one uninitializes — and the rest are the cousins at the function family reunion 🧚💜 Every single one of them made the list, and every single one is worth a read. Go off, cross-references 📚

---

quick lil heads up: nothing here is a warning, nothing here is deprecated — she's just a small function in a big display core world. Handle her during the uninit sequence and you're golden 🫶
