STRUCT MPI3MR_INTR_INFO(9)

💖 struct mpi3mr_intr_info — Interrupt cookie information 💖

okay so bestie, welcome to the struct mpi3mr_intr_info(9) page from the Kernel API Manual ✨ this is the little bundle of joy that holds an interrupt cookie — like, the whole ID badge your IRQ shows at the door of the driver 🎀

---

🌸 NAME 🌸

struct mpi3mr_intr_info — Interrupt cookie information 🍪

---

✨ SYNOPSIS ✨

struct mpi3mr_intr_info {
    struct mpi3mr_ioc *mrioc;
    int os_irq;
    u16 msix_index;
    struct op_reply_qinfo *op_reply_q;
    char name[MPI3MR_NAME_LENGTH];
 };

---

🦋 Members 🦋

• mrioc — the adapter instance reference 💜 like, which controller this whole situation belongs to, yk?
• os_irq — the irq number 🔥 the actual number the OS handed over, no cap
• msix_index — the MSIx index ⭐ your fave little index into the MSIx table
• op_reply_q — the associated operational reply queue 🧚 the reply queue that's literally in this irq's group chat
• name — dev name for the irq claiming device 🎀 a char array, size MPI3MR_NAME_LENGTH, so the claiming device can introduce itself properly 💅

ngl this one's a short read, but it's giving essential 💀 you literally cannot run the driver without knowing which reply queue belongs to which irq, so yeah — read it, bestie 🙈
