STRUCT OCS_HCU_DEV(9)

💖 NAME 💖

okay so bestie, welcome to the struct ocs_hcu_dev(9) entry in the Kernel API Manual ✨ — this is literally the OCS HCU device context struct, and she’s here to hold all the device-context info. periodt 💅

✨ SYNOPSIS ✨

struct ocs_hcu_dev {
    struct list_head list;
    struct device *dev;
    void __iomem *io_base;
    struct crypto_engine *engine;
    int irq;
    struct completion irq_done;
    bool irq_err;
};

it’s giving “one struct, all the device details,” and honestly? iconic 🎀

🎀 Members 🎀

• list — list of device contexts. the whole lineup, bestie 💖
• dev — OCS HCU device. main character energy fr fr 👑
• io_base — base address of OCS HCU registers. where the register magic lives ✨
• engine — crypto engine for the device. slay 🦋
• irq — IRQ number. the number itself, no cap 💅
• irq_done — completion for IRQ. waiting room vibes 😭
• irq_err — flag indicating an IRQ error has happened. bestie, if this is set, something went sideways 💀
