smu_wbrf_support_check(9)

✨ smu_wbrf_support_check(9) ✨

okay so bestie, welcome to the Kernel API Manual 🎀 — this one's a lil function from the AMD power-management girlies and it's honestly so straightforward you're gonna slay it 💅

---

🌸 NAME 🌸

smu_wbrf_support_check — the vibe check for wbrf support, no cap 🔍

---

🦋 SYNOPSIS 🦋

void smu_wbrf_support_check (struct smu_context *smu );

literally one argument, one job, and it returns nothing (void girlies stay unbothered 💀). Look at her signature verbatim, don't touch:

void smu_wbrf_support_check (struct smu_context *smu );

---

💖 ARGUMENTS 💖

• smu — an smu_context pointer 🫶 that's it, that's the whole parameter. Just hand her the context struct and let her cook.

---

⭐ DESCRIPTION ⭐

So what does she do? She verifies the ACPI interface to check whether wbrf is supported ✅. That's the entire plot, bestie — a support check, a little "do we have wbrf yes or no" moment. Nothing extra, nothing sneaky, she's not out here changing state or doing side quests 🙈.
