STRUCT IWL_FW_ERROR_DUMP_DATA(9)

💅 struct iwl_fw_error_dump_data — data for one type

okay so this is a page from the Kernel API Manual and it's literally all about one tiny little struct, bestie. it's giving "small but mighty" energy. let's get into it ✨

🎀 SYNOPSIS

struct iwl_fw_error_dump_data {
    __le32 type;
    __le32 len;
    __u8 data[];
};

yes that's the whole thing. three fields. she's compact, she's iconic, she's the blueprint 💅

✨ Members

• type — this one's an enum iwl_fw_error_dump_type, so it's telling you what kind of data we're looking at here. the vibe check of the struct, if you will 🦋
• len — the length, and listen, it's the length starting from data. so like, data is where the counting begins, not the whole struct. important detail, don't forget it 🫶
• data — and this is just... the data itself. no cap. the actual goods. __u8 data[] — a flexible little array carrying the payload 🌸
