amdgpu_atcs_parse_functions(9)

💅 amdgpu_atcs_parse_functions — from the Kernel API Manual, bestie ✨

Okay so real talk, this is a page straight out of the amdgpu_atcs_parse_functions(9) corner of the kernel docs, and honestly? It's short, it's sweet, it slays. Let me break it down for you 🫶

---

🌸 NAME 🌸

amdgpu_atcs_parse_functions — the girl whose whole job is parsing supported functions 💁‍♀️

---

✨ SYNOPSIS ✨

void amdgpu_atcs_parse_functions (struct amdgpu_atcs_functions *f , u32
mask );

Literally that's it. Void return, two args, no drama. Iconic behavior tbh 💅

---

🎀 ARGUMENTS 🎀

• f — the supported functions struct, aka the little container where all the supported-function info gets parked 🚗✨
• mask — the supported functions mask, and no cap, it comes straight from ATCS 👑

---

🦋 DESCRIPTION 🦋

So here's the vibe: you take that supported functions mask from the ATCS function ATCS_FUNCTION_VERIFY_INTERFACE, and you use it to figure out which functions are actually supported. That's the whole thing. That's the assignment. And yes bestie, this applies to all asics — every single one, no exceptions, we love an inclusive king 🌈👑

Bestie this one's tiny but it matters — it's the little parser that tells the rest of the ACPI crew what ATCS can actually do 🔥

And that's the whole page, periodt 🎀 This gem lives out of ./drivers/gpu/drm/amd/amdgpu, dated October 2026, and honestly? Obsessed. Mwah 💋💖
