STRUCT IPU6_FW_ISYS_STREAM_CFG_DATA_ABI(9)

💅 struct ipu6_fw_isys_stream_cfg_data_abi(9) — Kernel API Manual, but make it make sense ✨

okay bestie, gather round 🫶 this is a page straight out of the Kernel API Manual and it's literally about struct ipu6_fw_isys_stream_cfg_data_abi — the ISYS stream configuration data. yes, also known as the ISYS stream configuration data structure. two names, one iconic little struct 👑

🌸 NAME 🌸

struct ipu6_fw_isys_stream_cfg_data_abi — ISYS stream configuration data 🎀

like… the ISYS stream configuration data structure, periodt. that's the whole vibe check.

---

✨ SYNOPSIS ✨

no cap, here's exactly what it looks like:

struct ipu6_fw_isys_stream_cfg_data_abi {
    struct ipu6_fw_isys_cropping_abi crop;
    struct ipu6_fw_isys_input_pin_info_abi input_pins[IPU6_MAX_IPINS];
    struct ipu6_fw_isys_output_pin_info_abi output_pins[IPU6_MAX_OPINS];
    u32 compfmt;
    u8 nof_input_pins;
    u8 nof_output_pins;
    u8 send_irq_sof_discarded;
    u8 send_irq_eof_discarded;
    u8 send_resp_sof_discarded;
    u8 send_resp_eof_discarded;
    u8 src;
    u8 vc;
    u8 isl_use;
    u8 sensor_type;
    u8 reserved;
    u8 reserved2;
 };

that's her. that's the whole cast 💜

🦋 Members 🦋

• crop — this one is for extended use, and ngl it's not used in FW currently. she's sitting there looking pretty for future plans 🎀
• input_pins — the input pin descriptors, aka the receipts for what's coming in.
• output_pins — the output pin descriptors, aka where the good stuff goes out 💅
• compfmt — the de-compression setting for User Defined Data. yes bestie, compression but make it de.
• nof_input_pins — number of input pins. literally just the count 🔢
• nof_output_pins — number of output pins. same energy, output edition.
• send_irq_sof_discarded — send irq on discarded frame sof response 👀 and this one has rules:
  • if '1' it will override the send_resp_sof_discarded and send the response 🔥
  • if '0' the send_resp_sof_discarded will determine whether to send the response
• send_irq_eof_discarded — send irq on discarded frame eof response, the eof sibling of the above:
  • if '1' it will override the send_resp_eof_discarded and send the response 🔥
  • if '0' the send_resp_eof_discarded will determine whether to send the response
• send_resp_sof_discarded — send response for discarded frame sof detected. important: used only when send_irq_sof_discarded is '0' — she's the backup plan 🫶
• send_resp_eof_discarded — send response for discarded frame eof detected. again, used only when send_irq_eof_discarded is '0' 🫶
• src — Stream source index, e.g. MIPI_generator_0, CSI2-rx_1. main character identifier energy ✨
• vc — MIPI Virtual Channel (up to 4 virtual per physical channel). four whole virtual channels per physical one, like hello?? 🌈
• isl_use — indicates whether the stream requires ISL and how. it's giving conditional queen.
• sensor_type — type of connected sensor, tobii or others, and the default is 0 💖
• reserved — a reserved field. she's reserved, that's the whole job 🙈
• reserved2 — a reserved field too. the sequel, equally reserved 💀

okay that's the whole page bestie, go read the header file, iykyk 🔥

and that's a wrap on the cute little sign-off 💖 this came from ./drivers/media/pci/intel/ipu6, dated October 2026, and the page itself is struct ipu6...cfg_data_abi(9). slay, bye 🎀✨
