ps3_chip_mask(9)

💅 ps3_chip_mask — kernel API manual energy ✨

okay so bestie, this is a page from the Kernel API Manual, and it's about ps3_chip_mask 🎀 — one little function that does one little job, and honestly? she ate.

---

🌸 NAME 🌸

ps3_chip_mask — sets an interrupt mask bit in ps3_bmp 🦋

---

✨ SYNOPSIS ✨

void ps3_chip_mask (struct irq_data *d );

that's it. that's the whole signature. void in, void out, no return value, no drama 💅

---

🫶 ARGUMENTS 🫶

• d — literally marked "-- undescribed --" in the original 😭 so like… nobody wrote down what it is. it's the struct irq_data * parameter, and past that, the docs are giving mystery. we don't know, she doesn't know, the manpage sure doesn't know 🙈

ngl the source material just says -- undescribed -- here, so I'm not gonna sit here and make something up. accuracy queen behavior only 👑

---

🔥 DESCRIPTION 🔥

so what does she actually do? two things, and they're both important:

1. Sets ps3_bmp.mask 🌈
2. Calls lv1_did_update_interrupt_mask ⭐

that's the whole vibe. mask bit set, then the update function gets called to actually go tell the hypervisor about it. main character energy, minimal dialogue, gets straight to the point fr fr 💜
