STRUCT IWL_FW_DBG_DEST_TLV_V1(9)

💅 struct iwl_fw_dbg_dest_tlv_v1 — NAME

okay so bestie, this is a Kernel API Manual page (yes we're reading the manual, we're thriving) and it's all about struct iwl_fw_dbg_dest_tlv_v1 — the struct that configures the destination of the debug data. that's it. that's the whole vibe. it's giving "where does the debug data GO" 🎀

---

✨ SYNOPSIS ✨

here's the literal shape of it, no cap, copy it exactly:

struct iwl_fw_dbg_dest_tlv_v1 {
    u8 version;
    u8 monitor_mode;
    u8 size_power;
    u8 reserved;
    __le32 base_reg;
    __le32 end_reg;
    __le32 write_ptr_reg;
    __le32 wrap_count;
    u8 base_shift;
    u8 end_shift;
    struct iwl_fw_dbg_reg_op reg_ops[];
};

look at her. iconic. 🌸

okay field-by-field, i got you:

• version — the version of the TLV. currently 0. (not me being version zero, lowkey a mood 😭)
• monitor_mode — this one's an enum iwl_fw_dbg_monitor_mode. yep. that's the whole description. i don't make the rules 💀
• size_power — the buffer size is gonna be 2^(size_power + 11). so yeah, do the math, it's a power-of-two situation, main character exponent energy ✨
• reserved — reserved. that's literally it. it's reserved. leave her alone. 🙈
• base_reg — addr of the base addr register (PRPH). keep an eye on that PRPH, it comes back twice 👑
• end_reg — addr of the end addr register (PRPH). twins with base_reg, matching outfits.
• write_ptr_reg — the addr of the reg of the write pointer.
• wrap_count — the addr of the reg of the wrap_count. yes the field and the reg have the same name, we stan consistency 💅
• base_shift — shift right of the base addr reg.
• end_shift — shift right of the end addr reg. (see? twins. told you.)
• reg_ops — array of registers operations. it's a flexible-array-member situation, reg_ops[], so she's open-ended, she's expansive, she's got range 🦋

🌈 Description

This parses IWL_UCODE_TLV_FW_DBG_DEST. short and sweet. that's genuinely the whole description. ate and left no crumbs. ⭐

like, that's twenty-four references. unhinged. obsessed. 🔥

and that's the whole page, bestie 🫶 this one came from ./drivers/net/wireless/intel/i... and it's dated October 2026, so yeah, slay from the future, see u next manual 💜
