STRUCT MHI_DEVICE(9)

💖 struct mhi_device(9) 💖

okay so welcome to the Kernel API Manual, bestie ✨ this is the whole entire page for struct mhi_device and like… it's the structure that represents an MHI device which binds to channels or is associated with controllers 🫶 that's the vibe, that's the whole thing, no notes.

---

🎀 NAME 🎀

struct mhi_device — the struct that reps an MHI device, the one that binds to channels or is associated with controllers. she's versatile like that 💅

---

✨ SYNOPSIS ✨

like, literally this shape, character for character, don't touch her:

struct mhi_device {
    const struct mhi_device_id *id;
    const char *name;
    struct mhi_controller *mhi_cntrl;
    struct mhi_chan *ul_chan;
    struct mhi_chan *dl_chan;
    struct device dev;
    enum mhi_device_type dev_type;
    int ul_chan_id;
    int dl_chan_id;
    u32 dev_wake;
 };

---

🦋 Members 🦋

okay now the girlies themselves, one by one, in order, no skipping 🙈

• id — pointer to the MHI device ID struct 🪪
• name — the name of the associated MHI device, her government name fr fr
• mhi_cntrl — the controller this device belongs to 👑
• ul_chan — the UL channel for the device ⬆️
• dl_chan — the DL channel for the device ⬇️
• dev — the driver model device node for the MHI device 🌱
• dev_type — the MHI device type 🏷️
• ul_chan_id — the MHI channel id for UL transfer 🔢
• dl_chan_id — the MHI channel id for DL transfer 🔢
• dev_wake — the device wakeup counter ⏰ (she's counting, she's always counting)

bestie I need you to know this was all sourced straight from ./include/linux — that's the whole directory it lives in, not a vibe I made up 💀

and that's the page!! October 2026 is when this dropped btw, so you're getting the freshest possible lore 🦋 mwah, go read mhi.h, she's iconic and she's waiting for you 💖✨🎀
