intel_dpll_get_freq(9)

💖 intel_dpll_get_freq(9) 💖

okay bestie, welcome to the Kernel API Manual ✨ this page is about one lil function with big main-character energy: intel_dpll_get_freq. it's giving “calculate the DPLL's output frequency,” and honestly? slay. 💅

---

🌸 NAME 🌸

intel_dpll_get_freq — calculate the DPLL's output frequency 🎀

---

✨ SYNOPSIS ✨

int intel_dpll_get_freq (struct intel_display *display , const struct intel_dpll *pll , const struct intel_dpll_hw_state *dpll_hw_state );

that's the whole signature, no cap. 📜

---

🎀 ARGUMENTS 🎀

• display — the intel_display device, aka the display situation we're working with 🖥️
• pll — the DPLL you want to calculate the output frequency for 👑
• dpll_hw_state — the DPLL state you're using to calculate that output frequency 🧚

---

🦋 DESCRIPTION 🦋

so basically: return the output frequency corresponding to pll's passed-in dpll_hw_state. that's it, that's the vibe check ✅

you hand it the pll and the dpll_hw_state, and it gives you back the matching output frequency. lowkey iconic, highkey useful. 💖
