💖 smu7_set_max_fan_rpm_output(9) 💖

okay bestie, welcome to the Kernel API Manual — this one's a lil function that literally just tells the fan how hard it's allowed to go. Setting a max operating fan output RPM, no cap. 🌀

---

✨ NAME ✨

smu7_set_max_fan_rpm_output — sets the maximum target operating fan output RPM. that's it, that's the whole vibe. your fan will not exceed this. periodt. 🔥

---

🎀 SYNOPSIS 🎀

int smu7_set_max_fan_rpm_output (struct pp_hwmgr *hwmgr , uint16_t us_max_fan_rpm );

---

🦋 ARGUMENTS 🦋

• hwmgr — the address of the powerplay hardware manager. like, hand me the hwmgr and i'll know which GPU we're talking about 💅
• us_max_fan_rpm — max operating fan RPM value. the ceiling. the limit. the "girl, not louder than this" number 🌸

---

🌈 RETURN 🌈

the response that came from the SMC. literally whatever the SMC says back — that's what you get. 👑

and that's the whole page, mwah 💋 — brought to you by the source ./drivers/gpu/drm/amd/pm/power..., dated October 2026, and yeah we're still calling it smu7_set_max_fan_rpm_output(9) at the bottom because consistency is iconic. ✨🎀
