ENUM IWL_FW_ERROR_TYPE(9)

💅 enum iwl_fw_error_type 💅

okay so this is a page from the Kernel API Manual (enum iwl_fw_error_type(9)) and it's literally all about telling you why your wifi firmware threw a tantrum. every possible reason, enumerated, no cap. let's get into it 🫶

---

✨ NAME ✨

enum iwl_fw_error_type — FW error types/sources 🌸

like, the whole taxonomy of "what went wrong bestie" for the firmware. iconic honestly.

---

🦋 SYNOPSIS 🦋

enum iwl_fw_error_type {
    IWL_ERR_TYPE_IRQ ,
    IWL_ERR_TYPE_NMI_FORCED ,
    IWL_ERR_TYPE_RESET_HS_TIMEOUT ,
    IWL_ERR_TYPE_CMD_QUEUE_FULL ,
    IWL_ERR_TYPE_TOP_RESET_BY_BT ,
    IWL_ERR_TYPE_TOP_FATAL_ERROR ,
    IWL_ERR_TYPE_TOP_RESET_FAILED ,
    IWL_ERR_TYPE_DEBUGFS

};

look at her. eight little constants, all lined up, all ready to snitch on your device 💀

🎀 Constants 🎀

• IWL_ERR_TYPE_IRQ — the "normal" FW error, coming at you through an IRQ 💖 (yes, "normal" is in quotes in the original too — the vibes are immaculate, the error is not)
• IWL_ERR_TYPE_NMI_FORCED — the driver straight up forced an NMI. not the hardware's idea, not a coincidence, the driver did that on purpose 🔥
• IWL_ERR_TYPE_RESET_HS_TIMEOUT — the reset handshake timed out 😭 and here's the important part: any debug collection has to happen synchronously, because the device is going to be shut down. like, collect your receipts now bestie, the door is closing 🚪💨
• IWL_ERR_TYPE_CMD_QUEUE_FULL — command queue was full. too many girlies in the queue, literally 🙈
• IWL_ERR_TYPE_TOP_RESET_BY_<wbr>BT — a TOP reset that was initiated by BT 🦋
• IWL_ERR_TYPE_TOP_FATAL_ERROR — TOP fatal error 💀 that's it, that's the description, and honestly? it ate. fatal is fatal.
• IWL_ERR_TYPE_TOP_RESET_FAILED — the TOP reset failed. a reset that reset nothing. embarrassing for everyone involved 😭
• IWL_ERR_TYPE_DEBUGFS — an error/reset indication coming from debugfs ⭐

👑 SEE ALSO 👑

go read these next, bestie, they're the supporting cast and they all understood the assignment:

• Kernel file ./drivers/net/wireless/intel/iwlwifi/iwl-op-mode.h
• Operational mode - what is it ?(9)
• Life cycle of the Operational mode(9)
• enum iwl_fw_error_context(9)
• struct iwl_fw_error_dump_mode(9)
• struct iwl_op_mode_ops(9)
• struct iwl_op_mode(9)

---

quick reminder that IWL_ERR_TYPE_RESET_HS_TIMEOUT is the dramatic one — debug collection must happen synchronously because the device is getting shut down. no time for a lil coffee break, fr fr 💅
