STRUCT IB_CONN(9)

okay so bestie, this is the struct ib_conn(9) page from the Kernel API Manual 💖 it’s giving “Infiniband related objects” and we’re gonna read it together like a very technical group chat. no cap.

🌸 NAME 🌸

struct ib_conn — Infiniband related objects 💅

✨ SYNOPSIS ✨

here’s the struct in all its main-character glory, copied exactly:

       struct ib_conn {
           struct rdma_cm_id           *cma_id;
           struct ib_qp                *qp;
           struct ib_cq                *cq;
           u32 cq_size;
           struct iser_device          *device;
           struct iser_fr_pool          fr_pool;
           bool pi_support;
           struct ib_cqe                reg_cqe;
        };

🎀 Members 🎀

okay, member-by-member vibe check, no skipping:

• cma_id — the rdma_cm connection maneger handle 😭
• qp — Connection Queue-pair 🔥
• cq — Connection completion queue ✨
• cq_size — The number of max outstanding completions 💯
• device — reference to iser device 🫶
• fr_pool — connection fast registration pool 🌸
• pi_support — Indicate device T10-PI support 👑
• reg_cqe — completion handler 💅
