intel_cdclk_init_hw(9)

okay bestie, welcome to the intel_cdclk_init_hw(9) page from the Kernel API Manual ✨ this one is short but iconic, fr fr.

🌸 NAME 🌸

intel_cdclk_init_hw — initialize CDCLK hardware 🎀

🦋 SYNOPSIS 🦋

void intel_cdclk_init_hw (struct intel_display *display );

🎀 ARGUMENTS 🎀

• display — the display instance, periodt. That's the main character being passed in.

🔥 DESCRIPTION 🔥

So this function initializes CDCLK, bestie. The main quest is initializing display->cdclk.hw and sanitizing the state of the hardware if needed. It's generally done only during the display core initialization sequence — after that, the DMC takes care of turning CDCLK off/on as needed. slay 💅
