ps3_chip_unmask(9)

💅 ps3_chip_unmask — like, the kernel API manual, section 9, bestie ✨

Okay so we're deep in the Kernel API Manual today and this little icon is ps3_chip_unmask(9) — yes, section nine, the fancy kernel-functions one 🎀

---

🌸 NAME 🌸

ps3_chip_unmask — clears an interrupt mask bit in ps3_bmp. That's it. That's the whole vibe check. 💫

---

✨ SYNOPSIS ✨

void ps3_chip_unmask (struct irq_data *d );

Returns literally nothing (void, she's mysterious like that 🙈) and takes exactly one thing.

---

🦋 ARGUMENTS 🦋

• d — so the docs say "-- undescribed --"... which is giving "the group project slide that just says TODO" 😭 ngl the manual is leaving us on read here. It's a struct irq_data * pointer, that part we do know, but the description? Not me having nothing to work with. The official page just does not describe it. Periodt. 💀

---

🔥 DESCRIPTION 🔥

So what does she actually do? Two things, and honestly she ate:

• Clears ps3_bmp.mask 💫
• Calls lv1_did_update_interrupt_mask 🎀

Lowkey iconic that it's only two steps. Main character energy. No cap, that's the entire description. 👑

Heads up bestie: the argument d is officially marked as undescribed in the original page, so don't come for me — I'm not inventing lore that isn't there 🙈

And that's the whole page! 💖 This cutie dropped from ./arch/powerpc/platforms/ps3 back in October 2026 — a whole moment in time, slay 🫶⭐
