STRUCT KNAV_QUEUE_INST(9)

✨ struct knav_queue_inst(9) ✨

okay bestie, welcome to the struct knav_queue_inst glow-up 💅 this is a page from the Kernel API Manual and it's literally all about the properties of a qmss queue instance. no cap. let's get into it 🎀

🌸 NAME 🌸

struct knav_queue_inst — qmss queue instance properties 🦋

---

✨ SYNOPSIS ✨

struct knav_queue_inst {
    u32 *descs;
    atomic_t desc_head, desc_tail, desc_count;
    struct knav_acc_channel *acc;
    struct knav_device              *kdev;
    struct knav_range_info          *range;
    struct knav_qmgr_info           *qmgr;
    u32 id;
    int irq_num;
    int notify_needed;
    atomic_t num_notifiers;
    struct list_head                handles;
    const char                      *name;
    const char                      *irq_name;
 };

yes she's got range, she's got structures, she's got atomic_t counters — main character energy fr fr 👑

• acc — accumulator channel pointer 💫
• kdev — qmss device pointer 🫶
• range — range info 🌈
• qmgr — queue manager info 👑
• id — queue instance id ⭐
• irq_num — irq line number 🌸
• notify_needed — notifier needed based on queue type. lowkey conditional, highkey important 💀
• num_notifiers — total notifiers 🧚
• handles — list head 📋
• name — queue instance name 🎀
• irq_name — irq line name 💜

ngl bestie, that's the whole struct — every member accounted for, nothing skipped, we ate and left no crumbs 💅🙈

mwah 💖 that's a wrap! this came straight out of ./drivers/soc/ti and it's dated October 2026 — same title, same struct knav_queue_inst(9), iconic behavior only 🌟🫶
