pdc_model_info(9)

💅 pdc_model_info(9) — like, the Kernel API Manual page you actually wanna read ✨

okay so welcome to the <pink>Kernel API Manual</pink> entry for pdc_model_info, bestie — this is the little firmware call that spills all the tea about your processor's model info 🫖👑

---

🌸 NAME 🌸

pdc_model_info — returns model information about the processor, no cap 💖

---

✨ SYNOPSIS ✨

int pdc_model_info (struct pdc_model *model );

that's it, that's the whole vibe check 🦋

---

🎀 ARGUMENTS 🎀

• model — the return buffer, aka the cute little spot where all the info gets dropped off 🎁 this is where you get your answers back, so don't forget to hand it over, mwah 💋

ngl this page is short but it's giving "small but mighty" 💀 don't sleep on it

okay bestie that's the whole page 🌈 this cutie came from the <purple>./arch/parisc/kernel</purple> source, dated <pink>October 2026</pink> — slay, go read some more man pages, ily, bye 🎀🫶💜
