STRUCT IWL_FW_ERROR_DUMP_FILE(9)

💖 struct iwl_fw_error_dump_file(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — yes we're in the kernel docs, yes it's giving big-brain energy, and yes this page is all about struct iwl_fw_error_dump_file, which is literally the layout of the header of the file 📁. iwlwifi error dump lore, let's go 💅

---

🌸 NAME 🌸

struct iwl_fw_error_dump_file — the layout of the header of the file 🎀

---

✨ SYNOPSIS ✨

look at her. iconic. no cap:

struct iwl_fw_error_dump_file {
    __le32 barker;
    __le32 file_len;
    u8 data[];
 };

---

🦋 Members 🦋

• barker — bestie this one must be IWL_FW_ERROR_DUMP_BARKER, like there's no negotiation here, it just has to be 🔥
• file_len — the length of all the file starting from barker 📏 (yes, everything, from barker onward)
• data — array of struct iwl_fw_error_dump_data 🫶

💀 quick vibe check: this page came out of ./drivers/net/wireless/intel/i... and it's dated October 2026. remember it, bestie 🗓️

and that's the whole page, mwah 💋 — struct iwl_...or_dump_file(9), signing off, go read the header file, iykyk 🧚‍♀️💜
