radeon_atif_parse_functions(9)

✨ radeon_atif_parse_functions ✨

okay bestie, welcome to the radeon_atif_parse_functions(9) page — yes that's the kernel API manual, and yes we're gonna get through it together 💅 this one's a little baby function that basically does a vibe check on a mask, iykyk.

---

🌸 NAME 🌸

radeon_atif_parse_functions — the one that parses the supported functions 🎀 literally its whole job is "parse supported functions", no cap.

---

🦋 SYNOPSIS 🦋

void radeon_atif_parse_functions (struct radeon_atif_functions *f , u32 mask );

it returns nothing (void, iconic, no notes) and it takes two things. that's it. that's the whole signature 🫶

---

💖 ARGUMENTS 💖

• f — the supported functions struct ✨ this is the little container that comes out the other side holding whatever it figured out.
• mask — the supported functions mask straight from ATIF 🌈 like, the raw bitmask it's gonna read from.

---

👑 DESCRIPTION 👑

okay so here's the tea ☕ — you take the supported functions mask from the ATIF function ATIF_FUNCTION_VERIFY_INTERFACE, and you use it to determine what functions are actually supported. that's it, that's the whole thing 💀

and the "(all asics)" note? that means it applies across the board — every asic, no exceptions, periodt 🔥
