smu7_enable_...e_controller(9)

👑 NAME ✨

smu7_enable_smc_voltage_controller — okay bestie, this one is literally just "enable voltage control" 💅 that's the whole vibe, that's the whole function, and honestly? iconic.

(this page lives in the Kernel API Manual, section 9, in case you were wondering 🫶)

---

🌸 SYNOPSIS 🌸

int smu7_enable_smc_voltage_controller (struct pp_hwmgr *hwmgr );

Yep. One argument. One int coming back at you. Not me being obsessed with a function signature that fits in a single breath 😭✨

---

🦋 ARGUMENTS 🦋

• hwmgr — the address of the powerplay hardware manager. like, the actual pointer, bestie, not a copy, not a vibe, the address 💖 that's the whole thing you're handing over.

---

🎀 RETURN 🎀

always PP_Result_OK

no cap. always. it does not miss, it does not fail, it does not have a bad day — PP_Result_OK every single time 🔥 so like, don't go writing error-handling fanfic about this one, she's not giving that 🌈
