STRUCT PECI_DEVICE_ID(9)

💖 struct peci_device_id(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ today we're looking at struct peci_device_id — literally the little data blob PECI uses to match devices 🎀 it's smol, it's cute, it's giving "two fields and a dream" energy, and you're gonna understand it in like thirty seconds fr fr 💅

---

🌸 NAME 🌸

struct peci_device_id — PECI device data to match 🦋

like, the actual data that a PECI device gets matched against, no cap ✨

---

✨ SYNOPSIS ✨

struct peci_device_id {
    const void *data;
    u32 x86_vfm;
 };

that's the whole thing, bestie — two members, zero drama, main character energy 👑

---

🎀 Members 🎀

• data — a pointer to driver private data specific to the device 🫶 like, whatever extra secret info the driver wants to stash, this is where it lives (it's const void *, so don't go messing with it 💅)
• x86_vfm — the device vendor-family-model 🌈 this is a u32 holding the vendor/family/model triple — yes it's one field, yes it's packing all three, and yes it ate, we love a compact king 👑

bestie heads up: this page lives in ./drivers/peci, and it's dated October 2026 — yes, from the future 💀 the whole thing is part of the Kernel API Manual (that's the manual name, folded in near the top like I promised 💖), and it's signed off as struct peci_device_id(9) at the bottom. slay, that's the whole page, periodt 🌸🦋💜
