STRUCT IWL_FW_ERROR_DUMP_MODE(9)

💖 struct iwl_fw_error_dump_mode — error dump mode for callback 💖

okay so bestie, we're in the Kernel API Manual today (yes, the kernel, we're doing this 💅) and the star of the show is literally called struct iwl_fw_error_dump_mode. it's the error dump mode for a callback, and it's honestly giving tiny-but-load-bearing. two fields. that's it. but those two fields are doing so much, iykyk.

it lives in ./drivers/net/wireless/intel/iwlwifi/iwl-op-mode.h if you wanna go look at it with your own eyes 👀

✨ SYNOPSIS ✨

struct iwl_fw_error_dump_mode {
    enum iwl_fw_error_type type;
    enum iwl_fw_error_context context;
 };

two members. that's the whole struct. no cap. 🎀

🦋 Members 🦋

• type — the reason for the dump, like, why are we even doing this. its type is enum iwl_fw_error_type and it's per that enum, so go read the enum for the full menu of reasons 🌸
• context — the context for the dump, and heads up: it may also indicate that this call needs to be skipped 👀. and here's the part that's not a vibe, it's a rule — this MUST be checked before and after acquiring any locks in the op-mode! both. before and after. not one, not the other, both. fr fr, don't skip the second check, that's the whole point 🔥

bestie the all-caps MUST is not me being dramatic, it's the manpage being dramatic. check context before the locks, check it after the locks, every single time. periodt 💀

that's the whole page, bestie, short and iconic 👑 it's from the Kernel API Manual, and this little cutie is dated October 2026 — so yes, we're reading the future, slay ⭐ bye!! 💜✨
