✨ NAME ✨

smu7_get_memory_type — the whole entire job is finding out if memory is GDDR5. that's it. that's the function. no cap 🫶

🌸 SYNOPSIS 🌸

int smu7_get_memory_type (struct pp_hwmgr *hwmgr );

like, yes, it returns an int. and yes, it takes exactly one thing. we love a low-maintenance queen 👑

🦋 ARGUMENTS 🦋

• hwmgr — the address of the powerplay hardware manager. that's the whole argument. just the one. she doesn't need anything else, honestly 💅

---

⭐ RETURN ⭐

always 0. always. no drama, no edge cases, no "well actually it depends" — she said 0 and she meant 0. main character energy fr fr 😭🔥
