STRUCT IWL_FW_DBG(9)

🎀 struct iwl_fw_dbg(9) 🎀

okay so bestie, welcome to the Kernel API Manual — yes that's the manual name, and yes we're about to read a struct definition together like it's the group chat gossip of the day. this one is struct iwl_fw_dbg, and it's literally the debug data holder. let's get into it 💅

---

✨ NAME ✨

struct iwl_fw_dbg — debug data. that's it, that's the vibe. it's the struct that keeps all your debug info together, and honestly? iconic 🫶

---

🌸 SYNOPSIS 🌸

here's the whole thing, character for character, because we do not mess with the code:

struct iwl_fw_dbg {
    struct iwl_fw_dbg_dest_tlv_v1 *dest_tlv;
    u8 n_dest_reg;
    struct iwl_fw_dbg_conf_tlv *conf_tlv[FW_DBG_CONF_MAX];
    struct iwl_fw_dbg_trigger_tlv *trigger_tlv[FW_DBG_TRIGGER_MAX];
    size_t trigger_tlv_len[FW_DBG_TRIGGER_MAX];
    struct iwl_fw_dbg_mem_seg_tlv *mem_tlv;
    size_t n_mem_tlv;
    u32 dump_mask;
 };

like, look at all those fields. main character struct energy fr fr 👑

💖 Members 💖

okay now the fun part — every single member, explained, no skips, no summaries, we do not leave anyone out of the group chat:

• dest_tlv — points to the debug destination TLV (typically SRAM or DRAM). so it's telling you where the debug stuff is headed — sram or dram, depending. lowkey important ngl 🦋
• n_dest_reg — the num of reg_ops in dest_tlv. just keeping count, that's all. 💫
• conf_tlv — array of pointers to configuration HCMDs. an array, bestie. plural. 💅
• trigger_tlv — array of pointers to triggers TLVs. more arrays, more pointers, we stay unbothered. 🔥
• trigger_tlv_len — lengths of the dbg_trigger_tlv entries. it's giving "size matters" but in a struct way 🙈
• mem_tlv — Runtime addresses to dump. runtime addresses, specifically. 🍓
• n_mem_tlv — number of runtime addresses. yes, paired with mem_tlv above, they're a matching set, cute. 🎀
• dump_mask — bitmask of dump regions. it's a mask, it masks, we respect it. 🌈

and that's the whole page, no cap. this one came from ./drivers/net/wireless/intel/i... (yes it's truncated in the source, i'm not about to invent the rest, i would never 😭) and it's dated October 2026. slay, go forth and debug, you're literally so smart 💖✨🌟
