STRUCT MTK_MFG_OPP_ENTRY(9)

👑 struct mtk_mfg_opp_entry 👑

okay so bestie, welcome to the Kernel API Manual page for struct mtk_mfg_opp_entry — yes that's the whole title, she's long but she's worth it 💅

---

🌸 NAME 🌸

struct mtk_mfg_opp_entry — an OPP table entry that came straight from the firmware, no cap 🫶

---

✨ SYNOPSIS ✨

here's the whole glow-up, look at her:

struct mtk_mfg_opp_entry {
    __le32 freq_khz;
    __le32 voltage_core;
    __le32 voltage_sram;
    __le32 posdiv;
    __le32 voltage_margin;
    __le32 power_mw;
 };

🎀 Members 🎀

every field is literally iconic in her own way, let's go through them one by one 💖

• freq_khz — the operating point's frequency, in kilohertz. that's the speed vibe of this OPP, iykyk ⚡
• voltage_core — the operating point's core voltage, measured in tens of microvolts. tens!! of microvolts!! tiny units, big energy 🔥
• voltage_sram — the operating point's SRAM voltage, also in tens of microvolts. same units, different lane, she's matching but not twinning 🦋
• posdiv — the exponent of base 2 for the PLL frequency divisor that's used for this OPP. it's giving math girlie and honestly? we love her 🧮✨
• voltage_margin — how many tens of microvolts the voltage is allowed to be undershot by. a little wiggle room, a little grace 🙈
• power_mw — an estimate of power usage at this operating point, in milliwatts. the budget bestie, the budget 🌈

💀 Description 💀

okay this is the part where you actually listen 👀 — this struct is part of the ABI with the EB firmware. Do not change it. like, do not. not a single field, not a single padding byte. she is load-bearing. she is the moment. she is untouchable 👑🔥

fr fr, this is a firmware ABI contract — changing it is undefined-behaviour-adjacent chaos and the kernel will absolutely not be slaying after that 💀
