STRUCT XSDFEC_DEV(9)

🌸 struct xsdfec_dev(9) 🌸

okay bestie, welcome to the kernel API manual — this one's struct xsdfec_dev(9), and yes it's a whole driver data for SDFEC situation. buckle up 🎀

---

✨ NAME ✨

struct xsdfec_dev — the driver data for SDFEC, literally the glow-up container that holds everything the driver needs 🫶

---

✨ SYNOPSIS ✨

struct xsdfec_dev {
    struct miscdevice miscdev;
    struct xsdfec_clks clks;
    wait_queue_head_t waitq;
    struct xsdfec_config config;
    char dev_name[DEV_NAME_LEN];
    unsigned long flags;
    void __iomem *regs;
    struct device *dev;
    enum xsdfec_state state;
    spinlock_t error_data_lock;
    int dev_id;
    u32 isr_err_count;
    u32 cecc_count;
    u32 uecc_count;
    int irq;
    bool state_updated;
    bool stats_updated;
    bool intr_enabled;
 };

no cap, that's the whole struct, copied exactly, don't come for me 💅

✨ Members ✨

bestie this is the member-by-member breakdown, the main character roster of the struct 👑

• miscdev — the misc device handle. iconic little handle.
• clks — the clocks that the SDFEC driver manages. yes, it's clockin' ⏰
• waitq — the driver wait queue. it waits, we love that for it.
• config — the configuration of the SDFEC device. the settings, the vibes.
• dev_name — the device name. yes it has a name, be respectful ✨
• flags — spinlock flags. they're flags, they're spinning, they're locking.
• regs — the device physical base address. the physical address, fr fr.
• dev — a pointer to the device struct. pointer queen 🫶
• state — the state of the SDFEC device. current mood: stateful.
• error_data_lock — the error counter and states spinlock. literally guarding the error counters and states, not me being protective 😭
• dev_id — the device ID. identity ✨
• isr_err_count — the count of ISR errors. counting them, unfortunately.
• cecc_count — the count of Correctable ECC errors (SBE). correctable! we fix those 💖
• uecc_count — the count of Uncorrectable ECC errors (MBE). uncorrectable 💀 not great, not terrible — okay it's kinda terrible.
• irq — the IRQ number. interrupt me, bestie.
• state_updated — indicates the state was updated by the interrupt handler. the interrupt handler did that 🙈
• stats_updated — indicates the stats were updated by the interrupt handler. stats! updated! by the interrupt handler!
• intr_enabled — indicates IRQ is enabled. it's enabled, it's giving enabled energy.

✨ Description ✨

so basically: this structure contains the necessary state for the SDFEC driver to operate. that's it, that's the thesis statement — every field up there exists so the driver can actually function 🦋

okay that's the whole page, you ate that 🍓 this gem lives over in ./drivers/misc and the source/version + date on the original footer said October 2026 — so shoutout to October 2026 and the ./drivers/misc crew, mwah 💜 periodt.
