💅 smu7_get_mc_microcode_version(9) 💅

okay so bestie, we're in the Kernel API Manual today and the main character of this page is smu7_get_mc_microcode_version — say that five times fast, i literally dare you 🫶. She's a lil function that goes and finds the MC microcode version and then stores it in the HwMgr struct. Like, she's the friend who screenshots the important stuff and saves it to the group chat so nobody has to go looking for it again. iconic behavior, no notes. ✨

✨ NAME ✨

smu7_get_mc_microcode_version — finds the MC microcode version and stores it in the HwMgr struct 💖

---

🌸 SYNOPSIS 🌸

int smu7_get_mc_microcode_version (struct pp_hwmgr *hwmgr );

that's it. that's the whole vibe check. one arg, and a return type of int sitting there looking pretty. 🎀

🦋 ARGUMENTS 🦋

• hwmgr — literally just the address of the powerplay hardware manager. that's her. that's the whole entry. hand her over and you're good 👑

---

⭐ RETURN ⭐

always 0. yeah. always. not "usually", not "most of the time" — always. she does not miss, she does not fail, she does not give you a weird number to decode. just 0, every single time, like a text back from your bestie at 3am. 💀💖
