STRUCT ISCSI_CID_QUEUE(9)

💅 struct iscsi_cid_queue — the Kernel API Manual glow-up

okay bestie, so this is struct iscsi_cid_queue(9) from the Kernel API Manual, and it's basically the per-adapter bookkeeping situation for iSCSI CIDs. lowkey iconic. let's get into it 🎀

---

✨ NAME ✨

struct iscsi_cid_queue — the per adapter iscsi cid queue. that's it, that's the whole vibe 🦋

---

✨ SYNOPSIS ✨

here's the whole struct, copied exactly, no cap:

struct iscsi_cid_queue {
    void *cid_que_base;
    u32 *cid_que;
    u32 cid_q_prod_idx;
    u32 cid_q_cons_idx;
    u32 cid_q_max_idx;
    u32 cid_free_cnt;
    struct qedi_conn **conn_cid_tbl;
 };

---

🌸 Members 🌸

these are the fields, and yes every single one matters 💖

• cid_que_base — the queue base memory. it's a void *, so it's giving mysterious main character energy ✨
• cid_que — the queue memory pointer, a u32 *. this is the actual pointer-pointer situation, iykyk
• cid_q_prod_idx — the produce index 👑
• cid_q_cons_idx — the consumer index 🫶
• cid_q_max_idx — the max index. it's used to detect the wrap around condition 🌈 (yes bestie, wrap-around detection is real and it's doing the most)
• cid_free_cnt — the queue size 🍓
• conn_cid_tbl — the iscsi cid to conn structure mapping table. it's a struct qedi_conn **, so like, a table of pointers to pointers to conns. table-ception fr fr 💅

💜 Description 💜

Per adapter iSCSI CID Queue. that's the whole description and honestly? slay. short, sweet, to the point. 💀

⭐ SEE ALSO ⭐

• the kernel file ./drivers/scsi/qedi/qedi.h — go read it bestie, it's right there 🔥

ngl this page is a little brief, but that's just how the kernel docs roll sometimes. no invented lore, no extra claims — we keep it exactly as the source says. 🙈

and that's the page!! brought to you by ./drivers/scsi/qedi, October 2026 edition, from the Kernel API Manual. drink some water, hydrate, and go map some cids to conns 🧚 💜✨
