amd_wbrf_register_notifier(9)

💖 amd_wbrf_register_notifier 💖

okay bestie, welcome to the Kernel API Manual entry for amd_wbrf_register_notifier — yes that's a whole mouthful, no I will not be shortening it, it's iconic as is ✨

---

🌸 NAME 🌸

amd_wbrf_register_notifier — the function you call to register for notifications of frequency band update. that's literally the whole vibe: you sign up, you get pinged when the frequency band changes. slay 🎀

---

✨ SYNOPSIS ✨

int amd_wbrf_register_notifier (struct notifier_block *nb );

that's it. one argument. one int coming back at you. clean, minimal, main character energy 💅

---

🦋 ARGUMENTS 🦋

• nb — your driver's notifier block. like, the lil mailbox where the notifications get dropped off, y'know? you hand it over and the kernel knows where to find you 📬

---

💜 DESCRIPTION 💜

okay so here's the tea: if you're a consumer, you gotta register yourself through this API. that's the move. that's how you get in the group chat 💬

and once you're registered? you get notified on the frequency band updates from other producers. yes, other producers — you're not the one making the updates, you're the one receiving them. the way that works is genuinely so satisfying tbh. you're subscribed. you're in the loop. periodt 🔥

---

🔥 RETURN 🔥

• 0 — registering a consumer driver successfully. we love a clean zero. that's a W 🏆
• negative error code — failure 😭 something went wrong, it's giving "not today". the return value will be negative and you should absolutely check it, ngl.
