main(9)

✨ main(9) ✨

okay so bestie, buckle up — this one's from the Kernel API Manual (yep, that's the manual name, we're fancy now 💅). It's page main(9) and it's literally the glow-up story of how an SPU saves its whole vibe before things get real. 🦋

---

🌸 NAME 🌸

• main — the entry point for SPU-side context save. literally where the saving starts, no cap 💖

---

🎀 SYNOPSIS 🎀

int main

(no parentheses, no args, just vibes — that's exactly how it's written, i don't make the rules 🫶)

---

✨ DESCRIPTION ✨

so this code lowkey deviates from the documented sequence, and honestly? it's giving main character energy. here's exactly how it goes down:

1. The EA for LSCSA is passed from PPE in the signal notification channels. 📨 (yes, through the signal notification channels — that's the whole bit, periodt)
2. All 128 registers are saved by crt0.o. all of them. every single one. not 127, not "most" — 128. 🔥👑

no cap, that's the entire description. short, iconic, ate. 💅

and that's the page bestie!! 🍓 the source/version strut is ./arch/powerpc/platforms/cell/... and it's dated October 2026, tagged with main(9) at the end — so you always know exactly which little slay this is 💜🧚⭐
