💅 amdgpu_atif_handler(9)

okay so bestie, welcome to the Kernel API Manual page for amdgpu_atif_handler — yes that's the whole name, no notes, it's giving very-long-function-name energy and honestly? iconic. ✨

---

🎀 NAME 🎀

amdgpu_atif_handler — handle ATIF notify requests

(this function literally handles ATIF notify requests, that's the whole vibe, no cap)

---

🦋 SYNOPSIS 🦋

int amdgpu_atif_handler (struct amdgpu_device *adev , struct
       acpi_bus_event *event );

like, it takes two things and gives you back an int. that's it. that's the function. 🫶

---

🌸 ARGUMENTS 🌸

• adev — an amdgpu_device pointer 💖 (the GPU's whole little identity card)
• event — the atif sbios request struct ✨ (this is the thing being checked, bestie)

---

🔥 DESCRIPTION 🔥

So what does it actually do? It checks the acpi event, and if that event matches an atif event, it handles it. That's it. That's the whole job. Lowkey a vibe check on the event, and only the ones that pass the vibe check get handled. 💅

not me describing a kernel function like it's a group chat gatekeeper, but here we are 🧚

---

⭐ RETURN ⭐

NOTIFY_BAD or NOTIFY_DONE, depending on the event. 🎀

so basically it comes back with a little verdict — good or bad — and you will be hearing about it. periodt. 💀
