amdgpu_atif_...fy_interface(9)

💅 amdgpu_atif_verify_interface(9) — like, the Kernel API Manual bestie ✨

okay so real talk, this is from the Kernel API Manual, and it's the glow-up page for amdgpu_atif_verify_interface. grab a strawberry drink 🍓 and let's get into it.

🌸 NAME 🌸

amdgpu_atif_verify_interface — verify ATIF, no cap

---

✨ SYNOPSIS ✨

noinline_for_stack int amdgpu_atif_verify_interface (struct amdgpu_atif *atif );

---

🎀 ARGUMENTS 🎀

• atif — the amdgpu atif struct. yeah. that's the whole vibe, she's just the struct 💅

---

💖 DESCRIPTION 💖

so what does she actually do. bestie. she executes the ATIF_FUNCTION_VERIFY_INTERFACE ATIF function — like, literally calls it — which initializes ATIF and figures out which features are actually supported (and yes, this is on all asics, every single one, no exceptions 🫶).

returns 0 on success, error on failure. that's it. that's the whole arc. 😭
