STRUCT SEC_QUEUE(9)

💖 NAME 💖

struct sec_queue — literally all the tea about a HW queue 🫖✨

🌸 SYNOPSIS 🌸

ok bestie, here's the whole struct, no cap, character for character:

struct sec_queue {
    struct sec_dev_info *dev_info;
    int task_irq;
    char name[SEC_NAME_SIZE];
    struct sec_queue_ring_cmd ring_cmd;
    struct sec_queue_ring_cq ring_cq;
    struct sec_queue_ring_db ring_db;
    void __iomem *regs;
    u32 queue_id;
    bool in_use;
    int expected;
    unsigned long unprocessed[BITS_TO_LONGS( SEC_QUEUE_LEN)];
    typeof(struct sec_request_el *) *softqueue;
    bool havesoftqueue;
    spinlock_t queuelock;
    void *shadow[SEC_QUEUE_LEN];
 };

🎀 MEMBERS 🎀

okay so here's the vibe check on every member the page actually spills about 👇

• dev_info — the parent SEC device this queue belongs to. it's giving "who's your mom" energy 💅
• task_irq — the completion interrupt for the queue ⚡
• name — a human-readable queue description, and it's also used as the irq name. dual-purpose icon 👑
• regs — the iomapped device registers 🗺️
• queue_id — the index of the queue, used for naming and resource selection 🔢
• in_use — a flag that says whether the queue is in use. yes bestie, it's a flag that flags 🚩
• expected — the next expected element to finish, assuming we were in order. optimistic much 😭
• softqueue — a software queue used when chaining requirements prevent direct use of the hardware queues 🧚
• havesoftqueue — a flag to say we have a queue — because we may need one for the current mode 🦋
• queuelock — protects the soft queue from concurrent changes, so we avoid some potential loss of data races 🔒 (spinlock doing spinlock things, we stan)
• shadow — pointers back to the shadow copy of the hardware ring element, needed because we can't store any context reference in the bd element 🙈
