STRUCT IWL_TOF_RESPONDER_CONFIG_CMD_V9(9)

💖 struct iwl_tof_responder_config_cmd_v9(9) — Kernel API Manual 💖

okay bestie, buckle up, because we're digging into the struct iwl_tof_responder_config_cmd_v9 from the Kernel API Manual. yes, the whole manual. no, it's not that deep, but also it kind of is. this is the ToF AP mode struct — and the manpage literally says "(for debug)", so like… it's giving "we made this for testing and now it lives here forever" energy 🫶

✨ NAME ✨

struct iwl_tof_responder_config_cmd_v9 — ToF AP mode (for debug). that's it, that's the name, periodt 💅

---

🌸 SYNOPSIS 🌸

here's the whole vibe, character for character, don't touch anything:

struct iwl_tof_responder_config_cmd_v9 {
    __le32 cmd_valid_fields;
    __le32 responder_cfg_flags;
    u8 format_bw;
    u8 bss_color;
    u8 channel_num;
    u8 ctrl_ch_position;
    u8 sta_id;
    u8 reserved1;
    __le16 toa_offset;
    __le16 common_calib;
    __le16 specific_calib;
    u8 bssid[ETH_ALEN];
    u8 r2i_ndp_params;
    u8 i2r_ndp_params;
    __le16 min_time_between_msr;
    __le16 max_time_between_msr;
 };

like, look at that little guy. so many fields. so many u8s. we love a compact struct 🦋

🎀 Members 🎀

okay so now the main character energy: every single member, explained, no skips, no "you get the idea" 💀

• cmd_valid_fields — an iwl_tof_responder_cmd_valid_field moment. that's the type, that's the whole note, slay.
• responder_cfg_flags — iwl_tof_responder_cfg_flags. flags for the responder config, iykyk.
• format_bw — enum iwl_location_format_bw. the format/bandwidth situation ✨
• bss_color — the current AP bss_color. (yes it's a real field name, we're not kidding.)
• channel_num — the current AP Channel. hi channel, love your work 💖
• ctrl_ch_position — the coding of the control channel position relative to the center frequency. see iwl_mvm_get_ctrl_pos. it's giving "please consult the other function" energy.
• sta_id — index of the AP STA when in AP mode. very "you know who you are" of it.
• reserved1 — reserved. that's literally it. it's reserved. leave it alone 🙈
• toa_offset — Artificial addition [pSec] for the ToA — to be used for debug purposes, simulating station movement by adding various values to this field. ngl this is the fun one: you're faking movement by sprinkling numbers into a field 😭 iconic debug behaviour.
• common_calib — XVT: common calibration value.
• specific_calib — XVT: specific calibration value. (yes, they're a matching set, we Stan a duo 🎀)
• bssid — Current AP BSSID. u8 bssid[ETH_ALEN], of course.
• r2i_ndp_params — parameters for R2I NDP.
  • bits 0 - 2: max number of LTF repetitions
  • bits 3 - 5: max number of spatial streams (supported values are < 2)
  • bits 6 - 7: max number of total LTFs

see enum ieee80211_range_params_max_total_ltf. heads up: supported values for spatial streams are < 2, so don't go wild.

• i2r_ndp_params — parameters for I2R NDP.
  • bits 0 - 2: max number of LTF repetitions
  • bits 3 - 5: max number of spatial streams
  • bits 6 - 7: max number of total LTFs

see enum ieee80211_range_params_max_total_ltf. note this one does not repeat the < 2 note — keeping it exactly as written, bestie, no edits 💅

• min_time_between_msr — for non trigger based NDP ranging, minimum time between measurements in milliseconds. lowkey the responsible one of the pair.
• max_time_between_msr — for non trigger based NDP ranging, maximum time between measurements in milliseconds. the chaotic counterpart 🔥
