💅 smu7_patch_ppt_v1_with_vdd_leakage 💅

ok so this is a page from the Kernel API Manual, bestie — yes, the actual kernel API manual, we're in the big leagues now 🎀 and today's main character is smu7_patch_ppt_v1_with_vdd_leakage. say it with me: patch. ppt. v1. with. vdd. leakage. iconic, no notes. 🌸

✨ NAME ✨

smu7_patch_ppt_v1_with_vdd_leakage — changes the virtual leakage voltage to the actual value. that's it, that's the whole job, and she does it flawlessly 🫶

---

🦋 SYNOPSIS 🦋

void smu7_patch_ppt_v1_with_vdd_leakage (struct pp_hwmgr *hwmgr ,
       uint16_t *voltage , struct smu7_leakage_voltage *leakage_table );

like, literally the whole signature. returns void because she gives nothing back, she just does the thing 💅

---

💖 ARGUMENTS 💖

okay so here's who's showing up to the group chat:

• hwmgr — the address of the powerplay hardware manager. this is the mom friend of the operation, she holds everything together 🔥
• voltage — pointer to the changing voltage. yes bestie, a pointer, she's mutable, she's evolving ✨
• leakage_table — pointer to the leakage table. no cap, this is where the tea lives 🍓

ngl this page is short and sweet and that's the vibe — no hidden traps, no scary warnings, just a little voltage patch doing her little voltage patch things. periodt. 💜

okay that's the whole page bestie, we ate and left no crumbs 🧚 source lives over at ./drivers/gpu/drm/amd/pm/power... and the date stamp says October 2026 — so screenshot this before it time-travels on us 😭 mwah, stay slay, run man responsibly 💀✨
