intel_wakeref_get(9)

💖 intel_wakeref_get(9) 💖

okay so bestie, welcome to the Kernel API Manual — this one's all about intel_wakeref_get, and honestly? it's giving "hold my spot, i'm gonna go touch the hardware" energy ✨

---

🌸 NAME 🌸

intel_wakeref_get — acquire the wakeref 💅

---

🦋 SYNOPSIS 🦋

int intel_wakeref_get (struct intel_wakeref *wf );

---

🎀 ARGUMENTS 🎀

• wf — the wakeref, bestie. that's the one. 🫶

---

✨ DESCRIPTION ✨

So like, what this does is acquire a hold on the wakeref. Simple enough, right? But here's the iconic part 👑

The first user to do so is the main character — they will acquire the runtime pm wakeref, and then call the intel_wakeref_ops->get underneath the wakeref mutex. periodt. 🔥

⚠️ Heads up, because this part actually matters: intel_wakeref_ops->get is allowed to fail. If it does, the runtime-pm wakeref gets released and the acquisition is unwound, and an error is reported. So yeah — not me assuming it always works 😭 it does not.

---

💀 RETURN 💀

• 0 — slay 💅 the wakeref was acquired successfully
• a negative error code — otherwise. it said no. 🙈
