smu_wbrf_init(9)

💖 NAME 💖

<pink>smu_wbrf_init(9)</pink> is the Kernel API Manual page for init driver wbrf support. That's the whole name, bestie — short, sweet, and lowkey iconic. 💅

---

✨ SYNOPSIS ✨

Here's the exact call, no edits, no cap:

int smu_wbrf_init (struct smu_context *smu );

---

🫶 ARGUMENTS 🫶

• smu — the smu_context pointer. Hand it over, bestie; this is the context the function is working with. 🫶

---

🌸 DESCRIPTION 🌸

Okay so the vibe check: <pink>smu_wbrf_init()</pink> verifies the AMD ACPI interfaces and registers with the wbrf notifier chain if the wbrf feature is supported. That's the slay — she's checking the AMD ACPI interfaces first, then linking up with the wbrf notifier chain only when that feature is supported. 💖

It returns 0 on success. On failure, it returns an error — so don't ignore the return value, bestie, that's your sign to check what happened. 😭
