STRUCT QCE_DEVICE(9)

💖 NAME 💖

okay so welcome to the Kernel API Manual bestie, this page is struct qce_device(9) — the crypto engine device structure. that's it, that's the vibe. it's the big ol' struct that holds a QCE crypto engine together 🎀

✨ SYNOPSIS ✨

here's the whole struct, laid out exactly like this, no notes:

struct qce_device {
    struct crypto_queue queue;
    struct mutex lock;
    struct work_struct done_work;
    struct crypto_async_request *req;
    int result;
    void __iomem *base;
    struct device *dev;
    struct clk *core, *iface, *bus;
    struct icc_path *mem_path;
    struct qce_dma_data dma;
    int burst_size;
    unsigned int pipe_pair_id;
    int (*async_req_enqueue)(struct qce_device *qce, struct crypto_async_request *req);
    void (*async_req_done)(struct qce_device *qce, int ret);
 };

like… look at her. main character struct energy fr fr 👑

🌸 MEMBERS 🌸

• queue — the crypto request queue. the little lineup where requests wait their turn 🧚
• lock — the lock protects queue and req. yes both. it's giving bodyguard 💅
• done_work — workqueue context. that's where the finishing-up happens ✨
• req — current active request. the one actually on stage rn 🎤
• result — result of current transform. the vibe check report card 📋
• base — virtual IO base. the address-y home base 🏠
• dev — pointer to device structure. hi device bestie 🫶
• core — core device clock ⏰
• iface — interface clock ⏰
• bus — bus clock ⏰ (three clocks, three emoji, we love a trio)
• dma — pointer to dma data 📦
• burst_size — the crypto burst size 🔥
• pipe_pair_id — which pipe pair id the device using 🚰
• async_req_enqueue — invoked by every algorithm to enqueue a request 📥
• async_req_done — invoked by every algorithm to finish its request 📤

not me noticing mem_path is sitting up there in the struct but the Members list lowkey doesn't spell it out 😭🙈 it's in the struct, it's an struct icc_path *mem_path;, and that's literally all this page gives us. no cap.

alright bestie that's the whole page, go forth and enqueue responsibly 🦋💜

this has been struct qce_device(9) from the Kernel API Manual, straight outta ./drivers/crypto/qce, dated October 2026 — periodt. 🌈⭐
