STRUCT IPU6_FW_ISYS_FRAME_BUFF_SET_ABI(9)

💅 struct ipu6_fw_isys_frame_buff_set_abi(9) — from the Kernel API Manual, bestie

okay so picture this: you're deep in the Kernel API Manual and you bump into struct ipu6_fw_isys_frame_buff_set_abi, which is literally the ISYS frame buffer set (request). it's giving "one request, all the pins, all the irqs, all the vibes" ✨

🌸 NAME

struct ipu6_fw_isys_frame_buff_set_abi — the ISYS frame buffer set (aka the request, bestie) 🎀

---

✨ SYNOPSIS

struct ipu6_fw_isys_frame_buff_set_abi {
    struct ipu6_fw_isys_output_pin_payload_abi
output_pins[IPU6_MAX_OPINS];
    u8 send_irq_sof;
    u8 send_irq_eof;
    u8 send_irq_capture_ack;
    u8 send_irq_capture_done;
    u8 send_resp_sof;
    u8 send_resp_eof;
    u8 send_resp_capture_ack;
    u8 send_resp_capture_done;
    u8 reserved[8];
 };

like, that's the whole struct. she's iconic, she's organized, she has a reserved[8] because she's mysterious 🙈

🦋 Members (the whole cast, no skips)

• output_pins — output pin addresses. literally where the pins live, periodt 💅
• send_irq_sof — send irq on frame sof response
  • if '1' it will override the send_resp_sof and send the response 🔥
  • if '0' the send_resp_sof will determine whether to send the response 👑
• send_irq_eof — send irq on frame eof response
  • if '1' it will override the send_resp_eof and send the response 🔥
  • if '0' the send_resp_eof will determine whether to send the response 👑
• send_irq_capture_ack — send irq on capture ack ⭐
• send_irq_capture_done — send irq on capture done ⭐
• send_resp_sof — send response for frame sof detected, used only when send_irq_sof is '0' 🌸
• send_resp_eof — send response for frame eof detected, used only when send_irq_eof is '0' 🌸
• send_resp_capture_ack — send response for capture ack event
• send_resp_capture_done — send response for capture done event
• reserved — a reserved field 🫶 (she's reserved, respect her privacy ngl)

bestie lowkey pay attention to the priority thing: the send_irq_* flags are the main characters here. when they're '1' they override their send_resp_* besties, and when they're '0' the send_resp_* fields get to decide. iykyk 💖
