STRUCT UACCE_DEVICE(9)

💅 struct uacce_device(9) — kernel API manual, bestie edition 🎀

okay so bestie, we're in the struct uacce_device(9) page, from the Kernel API Manual — yes, that one, the header already told you, but I'm saying it again because context is everything ✨

---

🌸 NAME 🌸

struct uacce_device — literally the struct, that's it, that's the name. no description in the original, so no cap, we're not inventing one 🙈

---

✨ SYNOPSIS ✨

here's the whole thing, every field, character for character, do not touch it:

struct uacce_device {
    const char *algs;
    const char *api_ver;
    const struct uacce_ops *ops;
    unsigned long qf_pg_num[UACCE_MAX_REGION];
    struct device *parent;
    bool is_vf;
    u32 flags;
    u32 dev_id;
    struct cdev *cdev;
    struct device dev;
    struct mutex mutex;
    void *priv;
    struct list_head queues;
 };

🫶 Members 🫶

every single member, no skipping, we don't do that here 💖

• algs — supported algorithms. the whole point, honestly 👑
• api_ver — api version. gotta know which era of the API you're living in 🦋
• ops — pointer to the struct uacce_ops. the function table, the main character energy 🔥
• qf_pg_num — page numbers of the queue file regions. it's an array, [UACCE_MAX_REGION] sized, don't forget 🌸
• parent — pointer to the parent device. every device has a parent, deep 💜
• is_vf — whether virtual function. bool, so yes or no, that's the vibe check 💅
• flags — uacce attributes. u32, bitflags-ish, you know the drill ⭐
• dev_id — id of the uacce device. u32, the whole identity 🌈
• cdev — cdev of the uacce. char device representation, iconic 🎀
• dev — dev of the uacce. the actual struct device sitting right there inside 🧚
• mutex — protects uacce operation. yes, it protects the operation, so respect the lock, no sketchy unlocked nonsense 😭
• priv — private pointer of the uacce. void *, driver's little secret 🤫
• queues — list of queues. struct list_head, it's giving linked list 🍓

quick vibe check bestie: this page lives at ./include/linux, and the manual date on it is October 2026 — yes, October 2026, that's what it says, not my problem 🙈

so that's the whole page! source path ./include/linux, October 2026 date, and the manual is struct uacce_device(9) — slay, you read the whole thing, ate and left no crumbs 👑✨🫶
