STRUCT LEAPRAID_ADAPTER_INIT_REQ(9)

💖 struct leapraid_adapter_init_req — Adapter initialization request 💖

okay bestie, welcome to the Kernel API Manual page for struct leapraid_adapter_init_req — yeah, the header shortens her to struct leapr...ter_init_req(9), but we know her full government name 💅. This is the adapter initialization request struct: packed with fields, giving kernel-core, main-character energy. Let's unpack the whole fit ✨

✨ NAME ✨

struct leapraid_adapter_init_req — Adapter initialization request

🌸 SYNOPSIS 🌸

struct leapraid_adapter_init_req {
    u8 who_init;
    u8 r1;
    u8 chain_offset;
    u8 func;
    u8 r2[3];
    u8 msg_flg;
    __le32 driver_ver;
    __le16 msg_ver;
    __le16 header_ver;
    __le32 host_buf_addr;
    u8 r4[2];
    u8 host_buf_size;
    u8 host_msix_vectors;
    u8 r6[2];
    __le16 req_frame_size;
    __le16 rep_desc_qd;
    __le16 rep_msg_qd;
    __le32 sense_buffer_add_high;
    __le32 rep_msg_dma_high;
    __le64 task_desc_base_addr;
    __le64 rep_desc_q_arr_addr;
    __le64 rep_msg_addr_dma;
    __le64 time_stamp;
};

tiny heads-up: driver_ver is right there in the struct above, but the original Members list doesn't give it its own separate blurb — we're not inventing one, bestie 🙈

🫶 Members 🫶

• who_init — Initiator of the initialization. the one who kicks it all off, basically ✨
• r1 — Reserved. literally reserved, no cap 💅
• chain_offset — Chain offset.
• func — Function code.
• r2 — Reserved. again: reserved, bestie 🫶
• msg_flg — Message flags.
• msg_ver — Message version.
• header_ver — Header version.
• host_buf_addr — Host buffer address (non adapter-ref).
• r4 — Reserved. the reserved girlies stay reserved 🎀
• host_buf_size — Host buffer size (non adapter-ref).
• host_msix_vectors — Number of host MSI-X vectors.
• r6 — Reserved. yes, another one — reserved 💀
• req_frame_size — Request frame size.
• rep_desc_qd — Reply descriptor queue depth.
• rep_msg_qd — Reply message queue depth.
• sense_buffer_add_high — High 32-bit of sense buffer address.
• rep_msg_dma_high — High 32-bit of reply message DMA address.
• task_desc_base_addr — Base address of task descriptors.
• rep_desc_q_arr_addr — Address of reply descriptor queue array.
• rep_msg_addr_dma — Reply message DMA address.
• time_stamp — Timestamp. iconic, honestly ⭐
