STRUCT IWL_FW_INI_REGION_FIFOS(9)

💖 struct iwl_fw_ini_region_fifos 💖

okay bestie, quick vibe check — this is a page from the Kernel API Manual, and we're about to get into struct iwl_fw_ini_region_fifos, no cap. It's a little struct, it's giving "small but mighty," and it's literally the blueprint for reading Tx/Rx fifos. let's go 🎀

---

✨ NAME ✨

struct iwl_fw_ini_region_fifos — the configuration situation that tells the kernel how to read Tx/Rx fifos. that's it, that's the whole name, slay 💅

---

🌸 SYNOPSIS 🌸

struct iwl_fw_ini_region_fifos {
    __le32 fid[2];
    __le32 hdr_only;
    __le32 offset;
 };

look at her. three members, all __le32, all iconic. 👑

---

🦋 Members 🦋

• fid — the fifos ids array, fr fr. it's __le32 fid[2], and it's used to determine what fifos to collect. think of it as the "which ones, bestie?" field 🫶
• hdr_only — if this is non zero, you collect only the registers. that's the whole rule, no cap. zero = go off, non-zero = headers only, periodt 💀
• offset — the offset that gets added to the registers addresses. so like, the little nudge to your addresses. iconic behavior, honestly ✨

🧚 SEE ALSO 🧚

okay so this struct does NOT exist in a vacuum, and the kernel file that holds all the lore is:

Kernel file ./drivers/net/wireless/intel/iwlwifi/fw/api/dbg-tlv.h

and then the whole friend group, alphabetically-ish, in the order the page gives them:

• struct iwl_fw_ini_hcmd(9)
• struct iwl_fw_ini_header(9)
• struct iwl_fw_ini_addr_size(9)
• struct iwl_fw_ini_region_dev_addr_range(9)
• struct iwl_fw_ini_region_dev_addr(9)
• struct iwl_fw_ini_region_err_table(9)
• struct iwl_fw_ini_region_special_device_memory(9)
• struct iwl_fw_ini_region_internal_buffer(9)
• struct iwl_fw_ini_region_tlv(9)
• struct iwl_fw_ini_debug_info_tlv(9)
• struct iwl_fw_ini_allocation_tlv(9)

• struct iwl_fw_ini_hcmd_tlv(9)
• struct iwl_fw_ini_addr_val(9)
• struct iwl_fw_ini_conf_set_tlv(9)
• enum iwl_fw_ini_config_set_type(9)

• enum iwl_fw_ini_trigger_reset_fw_policy(9)
• enum iwl_fw_ini_dump_policy(9)
• enum iwl_fw_ini_dump_type(9)

that's the entire squad. go read them, iyk yk 😭💜

ngl bestie, if you're touching fid[2], hdr_only or offset without reading the structs around them, that's not main character energy — that's chaos energy. read the SEE ALSO. do it for me. 🙈
