STRUCT PS3_MMIO_REGION(9)

💅 struct ps3_mmio_region(9) — the kernel API manual, bestie edition 🎀

okay so you're in the kernel API manual (Kernel API Manual, section 9) and we're talking about struct ps3_mmio_region. buckle up, this one's short but it's literally the whole vibe for mmio on PS3, no cap ✨

---

🌸 NAME 🌸

struct ps3_mmio_region — a per device mmio state variables structure 💖

like, it's the lil bundle of state that lives per device so the mmio situation stays tracked. that's the whole job. iconic.

---

✨ SYNOPSIS ✨

struct ps3_mmio_region {
    struct ps3_system_bus_device *dev;
    const struct ps3_mmio_region_ops *mmio_ops;
    unsigned long bus_addr;
    unsigned long len;
    enum ps3_mmio_page_size page_size;
    unsigned long lpar_addr;
 };

there she is 👑 six fields, zero drama. dev is your struct ps3_system_bus_device *, mmio_ops is a const struct ps3_mmio_region_ops * (the ops, but make it const 💅), then bus_addr and len as unsigned long, a page_size that's an enum ps3_mmio_page_size, and finally lpar_addr as another unsigned long. chef's kiss.

🌈 Members 🌈

this is the members rundown section — the actual fields are the ones sitting pretty up in the struct above in SYNOPSIS, so peek there for the full lineup 🫶

---

💜 Description 💜

Current systems can be supported with a single region per device.

that's it. that's the description. one region per device and you're chilling — the current systems don't need more than that, fr fr. lowkey the most chill sentence in the whole manual.

okay and for the sign-off 🎀 this page comes from ./arch/powerpc/include/asm and it's dated October 2026, and the footer title is struct ps3_mmio_region(9) — so like, that's where it lives and when it was stamped. periodt. 💖✨🌸
