STRUCT MCB_DEVICE(9)

💅 struct mcb_device(9) — the Kernel API Manual, bestie edition 🫶

okay so listen. we are in the Kernel API Manual today and the main character is struct mcb_device — the MEN Chameleon Bus device. yes that's the whole vibe. no cap, this is the struct you're gonna want to know by heart ✨

---

📛 NAME 📛

struct mcb_device — it's the MEN Chameleon Bus device, fr fr. that's it. that's the name. iconic of it honestly 💅

---

✨ SYNOPSIS ✨

here's the whole thing, character for character, don't come for me about the spacing:

struct mcb_device {
    struct device dev;
    struct mcb_bus *bus;
    struct mcb_driver *driver;
    u16 id;
    int inst;
    int group;
    int var;
    int bar;
    int rev;
    struct resource irq;
    struct resource mem;
    struct device *dma_dev;
 };

look at her. chef's kiss. twelve fields and every single one eating 🔥

🎀 Members 🎀

okay bestie, let's go field by field, no skipping, i would never:

• dev — the device in kernel representation. this is the kernel's own glow-up version of the device 💖
• bus — the mcb bus this device is plugged to. where it lives, basically 🏠
• driver — the associated mcb_driver. the device's plus-one, its ride-or-die 🫶
• id — the mcb device id. its little name tag 🏷️
• inst — the instance in the Chameleon table. yes, in the Chameleon table 👑
• group — the group in the Chameleon table. same table, different column, we love structure ✨
• var — the variant in the Chameleon table. three flavors of Chameleon-table-core now 😭
• bar — the BAR in Chameleon table. a BAR! in the table! 🍓
• rev — the revision in Chameleon table. it's giving version history 🦋
• irq — the IRQ resource. struct resource irq energy ⚡

👀 tiny side note from your girl: the Members rundown stops at irq, but the struct itself also carries struct resource mem; and struct device *dma_dev;. those two show up in the synopsis and just… don't get a Members blurb here. i'm not gonna make stuff up about them — i'm just saying. iykyk 🙈
