STRUCT IWL_FW_INI_TRIGGER_TLV(9)

💅 NAME 💅

struct iwl_fw_ini_trigger_tlv — the trigger TLV, bestie ✨

okay so this is straight out of the Kernel API Manual, and it's giving "small struct, huge responsibility" energy. no cap, this little guy is the thing that decides what gets collected when it goes off. let's get into it 🎀

---

🌸 SYNOPSIS 🌸

struct iwl_fw_ini_trigger_tlv {
    struct iwl_fw_ini_header hdr;
    __le32 time_point;
    __le32 trigger_reason;
    __le32 apply_policy;
    __le32 dump_delay;
    __le32 occurrences;
    __le32 reserved;
    __le32 ignore_consec;
    __le32 reset_fw;
    __le32 multi_dut;
    __le64 regions_mask;
    __le32 data[];
};

like… the layout ate, honestly 💅 every field is exactly where it needs to be.

🦋 Members 🦋

• hdr — the debug header, aka the lil intro before the main character speaks 👑
• time_point — the time point. literally one of enum iwl_fw_ini_time_point, no improvising ✨
• trigger_reason — the trigger reason, iykyk 🫶
• apply_policy — uses enum iwl_fw_ini_trigger_apply_policy 🎀
• dump_delay — delay from trigger fire to dump, in usec. yes the unit matters, don't @ me 💀
• occurrences — max trigger fire occurrences allowed. it's giving "know your limits" 🙈
• reserved — unused. it's just sitting there, vibing 🦋
• ignore_consec — ignore consecutive triggers, in usec ⭐
• reset_fw — if non zero, will reset and reload the FW 😭 so like… mind the gap bestie
• multi_dut — initiate debug dump data on several DUTs 🔥
• regions_mask — mask of regions to collect 🌈
• data — trigger data 💖

---

✨ Description ✨

so a trigger that, upon firing, determines what regions to collect. that's it, that's the whole vibe — it fires, and then it's like "okay bestie, these regions, go" 💅 periodt.
