STRUCT MCB_BUS(9)

💅 struct mcb_bus(9) — like, the whole entire vibe

okay so bestie, welcome to struct mcb_bus, straight out of the Kernel API Manual (struct mcb_bus(9), if you're keeping receipts 📝). It's MEN Chameleon Bus and it's lowkey iconic. Let's get into it 🎀

---

✨ NAME ✨

struct mcb_bus — MEN Chameleon Bus. that's it, that's the whole name, she's concise and she ate 💅

---

🌸 SYNOPSIS 🌸

here's the queen herself, character for character, no notes:

struct mcb_bus {
    struct device dev;
    struct device *carrier;
    int bus_nr;
    u8 revision;
    char model;
    u8 minor;
    char name[CHAMELEON_FILENAME_LEN + 1];
    int (*get_irq)(struct mcb_device *dev);
 };

🦋 Members 🦋

• dev — the bus device. yes bestie, it's a struct device, she's just living her life in there 🫶
• carrier — a pointer to the carrier device (it's a struct device *, so like, handle with care ✨)
• bus_nr — the mcb bus number, an int, in case you were wondering which bus. it's this one 💀
• revision — the FPGA's revision number, a u8 — the FPGA said "this is my era" 👑
• model — the FPGA's model number, a char — main character energy fr fr
• get_irq — the callback to get the IRQ number. signature is int (*get_irq)(struct mcb_device *dev), so it takes a struct mcb_device * and hands you back an int, slay 🌈

ngl bestie, minor is right there in the struct — u8 minor; — but the Members list doesn't say a single word about her. mysterious. we simply don't know. 🙈 (i'm not gonna make something up, that's not the move.)
