amdgpu_atif_parse_functions(9)

💅 amdgpu_atif_parse_functions — like, the kernel API manual, bestie ✨

okay so this is the amdgpu_atif_parse_functions(9) page from the Kernel API Manual, and honestly it's short but it's important, so let's get into it 🎀

---

✨ NAME ✨

amdgpu_atif_parse_functions — parses the supported functions, periodt 💅

---

🌸 SYNOPSIS 🌸

void amdgpu_atif_parse_functions (struct amdgpu_atif_functions *f , u32
mask );

like, that's the whole signature. no return value, it's a void, she just does her thing 🦋

---

🫶 ARGUMENTS 🫶

• f — the supported functions struct, aka the lil container where all the "yep, supported" info gets stashed 💖
• mask — the supported functions mask, straight from ATIF 👑

---

🔥 DESCRIPTION 🔥

okay so the actual vibe: this function takes the supported functions mask that came out of the ATIF function ATIF_FUNCTION_VERIFY_INTERFACE and uses it to figure out which functions are actually supported — and yes, that's for all asics, no cap, every single one 🌈

it's giving "decode the mask, tell me what we can do" energy. iconic behavior honestly ⭐

fr fr that's the whole page — short, sweet, and lowkey doing a lot of heavy lifting in the amdgpu ACPI world 💀✨

and that's a wrap, bestie 🧚 from ./drivers/gpu/drm/amd/amdgpu, dated October 2026 — mwah, drink some water, and may your masks always be parsed correctly 🍓💖
