💅 amdgpu_atcs_verify_interface(9) — Kernel API Manual

Okay so bestie, welcome to the page for amdgpu_atcs_verify_interface(9) — yeah, the header up top abbreviates it as amdgpu_atcs_...fy_interface(9) because apparently even manpage headers get tired sometimes 💀. It's a Kernel API Manual joint, and it's all about verifying ATCS. Let's get into it. ✨

---

🎀 NAME 🎀

amdgpu_atcs_verify_interface — verify ATCS, that's literally the whole thing 🫶

---

✨ SYNOPSIS ✨

noinline_for_stack int amdgpu_atcs_verify_interface(struct amdgpu_atcs *atcs);

---

🌸 ARGUMENTS 🌸

• atcs — the amdgpu atcs struct 🧚 that's it, that's the argument

---

🦋 DESCRIPTION 🦋

Okay so what this bad boy does: it runs the ATCS_FUNCTION_VERIFY_INTERFACE ATCS function to initialize ATCS and figure out which features are supported — and yes, that's on all asics, no exceptions, we love a universal icon 👑

Then it returns 0 on success, or an error on failure. Periodt. That's the whole personality.

ngl it's giving "small function, big responsibility" — if the verify doesn't go through, you're getting an error back, not a vibe check 💅
