✨ intel_dmc_suspend(9) ✨

okay so this is a page straight out of the Kernel API Manual, bestie — buckle up 🎀

💅 NAME

intel_dmc_suspend — get the DMC firmware all cute and prepped before the system goes to sleep 😴✨

---

🌸 SYNOPSIS

void intel_dmc_suspend(struct intel_display *display);

---

🦋 ARGUMENTS

• display — the display instance, aka your main character for this function 🫶

---

🔥 DESCRIPTION

So here's the vibe: you're about to enter system suspend 😴 and before that happens, the DMC firmware needs to be prepared. That's literally the whole job 💅

What does "prepared" mean here? Two things, and they're both important:

• flushing pending work items — anything still queued up gets flushed out 🚿
• releasing any resources acquired during init — whatever got grabbed back at init time gets let go 🙈

That's it. That's the function. It handles its business so the suspend goes smoothly ✨ periodt.
