STRUCT IWL_FW_DBG_TRIGGER_TLV(9)

🌸 struct iwl_fw_dbg_trigger_tlv(9) — the Kernel API Manual, bestie edition 🌸

okay so like, this is the manpage you'd get from the kernel API manual for struct iwl_fw_dbg_trigger_tlv(9), and honestly? it's giving "one little struct doing a LOT of heavy lifting" ✨ read on, i promise it's cute.

---

💖 NAME 💖

struct iwl_fw_dbg_trigger_tlv — a TLV that describes the trigger 🎀 (yes that's literally it, that's the whole vibe)

---

✨ SYNOPSIS ✨

struct iwl_fw_dbg_trigger_tlv {
    __le32 id;
    __le32 vif_type;
    __le32 stop_conf_ids;
    __le32 stop_delay;
    u8 mode;
    u8 start_conf_id;
    __le16 occurrences;
    __le16 trig_dis_ms;
    u8 flags;
    u8 reserved[5];
    u8 data[];
 };

like, look at her. she's structured. she's aligned. she's iconic 💅

🫶 Members 🫶

• id — an enum iwl_fw_dbg_trigger. it's the ID, it says who she is, main character energy fr.
• vif_type — an enum iwl_fw_dbg_trigger_vif_type. yep, that's the vif type 🦋
• stop_conf_ids — a bitmap of configurations this trigger relates to. and here's the important part, bestie: if the mode is IWL_FW_DBG_TRIGGER_STOP, then if the bit corresponding to the currently running configuration is set, the data should be collected. so like, the bit has to be set for the config that's actually running, or nothing gets collected. no cap 👑
• stop_delay — how many milliseconds to wait before collecting the data after the STOP trigger fires. it's the "gimme a sec" field 😭
• mode — an enum iwl_fw_dbg_trigger_mode — can be stop / start of both.
• start_conf_id — if mode is IWL_FW_DBG_TRIGGER_START, this defines what configuration should be applied when the triggers kicks in. so when the trigger kicks in, this is the config that gets applied 🌸
• occurrences — number of occurrences. and listen, 0 means the trigger will never fire. like ever. zero. nothing. 💀 important.
• trig_dis_ms — the time, in milliseconds, after an occurrence of this trigger in which another occurrence should be ignored. it's the cooldown, she's resting 💅
• flags — an enum iwl_fw_dbg_trigger_flags. flags!! 🎀
• reserved — reserved (for alignment). she's there for the padding, and we respect her for it 🫶
• data — trigger data. the payload, the moment, the reason we're all here ⭐

ok that's the whole page, not a single detail dropped, we ate and left no crumbs 🍓

and finally, the cute lil sign-off: this one comes from ./drivers/net/wireless/intel/i... and it's dated October 2026, and the page itself is struct iwl_..._trigger_tlv(9) 🧚💜 love that for us, bye bestie! 💖
