intel_dpll_enable(9)

💅 intel_dpll_enable(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes, that Kernel API Manual, the one with all the i915 display lore. this page is about intel_dpll_enable, and honestly? it's a short one, and we're gonna slay it together. 🎀

---

✨ NAME ✨

intel_dpll_enable — enable a CRTC's DPLL. that's it. that's the whole job. girlboss behavior, no notes. 💖

---

🌸 SYNOPSIS 🌸

void intel_dpll_enable (const struct intel_crtc_state *crtc_state );

it returns void, so like… don't go looking for a return value, she gives you nothing back. just vibes and, presumably, an enabled DPLL. 💀

---

🦋 ARGUMENTS 🦋

• crtc_state — a const struct intel_crtc_state *, and lowkey the whole point: it's the CRTC, and its state, which has a DPLL. so the CRTC comes with its own DPLL attached, like a bestie who brings her own iced coffee. 🧊✨

---

💜 DESCRIPTION 💜

Enable DPLL used by crtc. that's the entire description, and honestly? iconic. no fluff, no filler, she said what she said. the DPLL that the CRTC is using gets enabled. periodt. 👑

ngl, this is a function we're describing, so like — the "enable" is literally in the name. main character energy from the very first line. 💅
