STRUCT IWL_FW_INI_FIFO_HDR(9)

💖 struct iwl_fw_ini_fifo_hdr(9) — the Kernel API Manual, but make it make sense 💖

okay bestie, so this is a page straight outta the Kernel API Manual and it's about struct iwl_fw_ini_fifo_hdr — literally just the little fifo range header. tiny struct, big responsibilities. let's get into it 🫶

---

🌸 NAME 🌸

struct iwl_fw_ini_fifo_hdr — the fifo range header, periodt. that's the whole vibe ✨

---

🦋 SYNOPSIS 🦋

struct iwl_fw_ini_fifo_hdr {
    __le32 fifo_num;
    __le32 num_of_registers;
};

look at her. two fields. no notes. 💅

---

🎀 Members 🎀

• fifo_num — the fifo number, duh. but here's the tea bestie: in the case of umac rx fifo, you gotta set BIT(31) to distinguish between lmac and umac rx fifos 👑 like it's literally the main character bit, don't forget it or the whole vibe check fails 😭
• num_of_registers — the num of registers to dump, and each one is dword size. dword size each. say it with me. dword. size. each. 🍓

✨ SEE ALSO ✨

okay so she runs with a whole squad, and every single one of them is getting their shoutout because we do not leave anyone out of the group chat 💜

ngl bestie, if you're poking at fifo dumps and you skip the BIT(31) thing, you're gonna have a bad time 😭 the lmac/umac distinction is not optional, it's giving load-bearing.

and that's the page!! this iconic little header came to you courtesy of the kernel file ./drivers/net/wireless/intel/i... and the date October 2026 — mwah, stan, bye 💅💖🌈
