STRUCT IWL_FW_INI_ERROR_DUMP_DATA(9)

🦋 struct iwl_fw_ini_error_dump_data(9) — a Kernel API Manual moment 🦋

okay so bestie, welcome to the Kernel API Manual, this one's coming at you straight out of the Intel iwlwifi firmware error-dump files and it's lowkey iconic. sit down, hydrate, let's get into it 💅

---

✨ NAME ✨

struct iwl_fw_ini_error_dump_data — literally just the data for one type, that's the whole vibe 🎀

---

🌸 SYNOPSIS 🌸

here's the struct itself, no cap, copy it exactly:

struct iwl_fw_ini_error_dump_data {
    u8 type;
    u8 sub_type;
    u8 sub_type_ver;
    u8 reserved;
    __le32 len;
    __u8 data[];
};

like… look at her. she's struct-shaped. she's got a flexible array member at the end. main character energy fr fr 💖

💅 Members 💅

• type — this one's an enum iwl_fw_ini_region_type, iykyk 🧚
• sub_type — the sub type id bestie, it's giving specification ✨
• sub_type_ver — the sub type version, yes there's a version, we love a versioned girl 🎀
• reserved — not in use 🙈 she's just sitting there taking up space, we respect her anyway
• len — the length starting from data, so it counts from where the data kicks in, not from the top of the struct 💀 important detail, don't forget it
• data — the data itself. yes. that's it. the data. 🍓

ngl that's the whole page. tiny page, huge energy. go dump those errors responsibly 💜

and that's the tea bestie — this icon came from ./drivers/net/wireless/intel/i..., dated October 2026, and she answers to struct iwl_...or_dump_data(9) 🦋✨ bye pookie, slay your kernel debugging 🌈
