STRUCT IPU6_FW_SEND_QUEUE_TOKEN(9)

✨ struct ipu6_fw_send_queue_token(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 — this one's called struct ipu6_fw_send_queue_token, and it's literally the ISYS send queue token. that's the whole vibe. it's a struct, it's small, it's iconic, and we're gonna get into it 🎀

---

🌸 NAME 🌸

struct ipu6_fw_send_queue_token — ISYS send queue token ✨ that's it, that's the name, no notes 💜

---

🦋 SYNOPSIS 🦋

here's the whole struct, copy-paste it exactly bestie, do NOT freestyle on me:

struct ipu6_fw_send_queue_token {
    u64 buf_handle;
    u32 payload;
    u16 send_type;
    u16 stream_id;
 };

that's four fields, all different widths, all doing their little thing 🫶

---

👑 Members 👑

okay so these are the members, and ngl the docs are kinda minimal on this one, but we're keeping every single one:

• buf_handle — buffer handle 🎀 that's what it is, that's what it does
• payload — payload ✨ yes bestie, the payload
• send_type — send_type 💫 the send type, as advertised
• stream_id — stream_id 🦋 and the stream id

no extra lore in the original, so no extra lore from me — i'm not out here inventing behaviour, that's not the vibe 🙈

💖 SEE ALSO 💖

bestie there are SO many cross-refs, like the whole friend group showed up to the group chat 😭

the kernel file this lives in is ./drivers/media/pci/intel/ipu6/ipu6-fw-isys.h, and then the structs:

• struct ipu6_fw_isys_output_pin_payload_abi(9)
• struct ipu6_fw_isys_output_pin_info_abi(9)
• struct ipu6_fw_isys_input_pin_info_abi(9)
• struct ipu6_fw_isys_cropping_abi(9)
• struct ipu6_fw_isys_stream_cfg_data_abi(9)
• struct ipu6_fw_isys_frame_buff_set_abi(9)
• struct ipu6_fw_isys_error_info_abi(9)
• struct ipu6_fw_isys_resp_info_abi(9)
• struct ipu6_fw_isys_proxy_error_info_abi(9)
• struct ipu6_fw_proxy_write_queue_token(9)
• struct ipu6_fw_resp_queue_token(9)
• struct ipu6_fw_proxy_resp_queue_token(9)
• struct ipu6_fw_proxy_send_queue_token(9)

that's the whole squad, all thirteen of them, no cap 🔥

warning bestie: the original page gives zero behaviour details beyond the field names — so if you need to know what actually happens at runtime, go read the header, don't come for me 😭

and that's the page!! 🧚💜 this gem came from the kernel source at ./drivers/media/pci/intel/ipu6, October 2026, and it's filed under struct ipu6..._queue_token(9) — slay, bye bestie 💅✨🍓
