💅 smu7_patch_p..._vdd_leakage 💅

okay so real talk, this page lives in the Kernel API Manual — the fancy manual name is smu7_patch_p..._vdd_leakage(9) and yes the title got truncated by the man page formatter, we don't talk about it 🫶

✨ NAME ✨

smu7_patch_ppt_v0_with_vdd_leakage — bestie, this one goes and changes your virtual leakage voltage over to the actual value. that's the whole vibe.

---

🌸 SYNOPSIS 🌸

void smu7_patch_ppt_v0_with_vdd_leakage (struct pp_hwmgr *hwmgr ,
uint32_t *voltage , struct smu7_leakage_voltage *leakage_table );

no return value, it's a void girlie — she does the thing and dips 💨

---

🎀 ARGUMENTS 🎀

• hwmgr — the address of the powerplay hardware manager. literally the main character of this whole operation 👑
• voltage — pointer to changing voltage. note the pointer bestie, we're editing in place, not returning a cute little copy 🙈
• leakage_table — pointer to leakage table. this is where the actual values come from, iykyk 🍓

okay that's the whole page, go patch some leakage voltage, slay 💅✨

sign-off besties: this beauty comes from ./drivers/gpu/drm/amd/pm/power... (yes, also truncated, the man page is going through something) and it's dated October 2026 — see u then 🧚💖
