STRUCT ISSEI_HECI_HW(9)

🌸 struct issei_heci_hw(9) — Kernel API Manual 🌸

okay so bestie, welcome to struct issei_heci_hw(9) 💅 this is the Kernel API Manual page for the issei heci hw specific data situation. no cap, it’s a whole little struct and we’re gonna go through every single member together 🫶

✨ NAME ✨

struct issei_heci_hw — issei heci hw specific data 🎀

✨ SYNOPSIS ✨

struct issei_heci_hw {
    const struct hw_heci_cfg *cfg;
    void __iomem *mem_addr;
    int irq;
    spinlock_t access_lock;
    u8 hbuf_depth;
};

🎀 Members 🎀

• cfg — per device generation config and ops. it’s giving “config + ops for this device generation” energy ✨
• mem_addr — io memory address, literally the address in io memory 🌸
• irq — device irq number 🔥
• access_lock — spinlock to protect hw access. yes ma’am, hardware access safety vibes 💅
• hbuf_depth — depth of hardware host/write buffer in slots. that’s the buffer depth, measured in slots 🦋
