STRUCT IWL_MCC_UPDATE_RESP_V3(9)

🦋 NAME 🦋

ok so bestie, welcome to struct iwl_mcc_update_resp_v3 — yes that's the whole name, it's a whole mouthful, i know 😭 — from the Kernel API Manual. this is literally the response to MCC_UPDATE_CMD, and it's carrying the new channel control profile map (if it changed, which, vibes) plus the new MCC (that's mobile country code for the uninitiated 🫶). and plot twist: the new MCC might not even be the one you asked for in MCC_UPDATE_CMD. it's giving "i heard you but i did my own thing" energy, no cap.

✨ SYNOPSIS ✨

ok here's the whole shape of her, exactly as she is, don't touch:

struct iwl_mcc_update_resp_v3 {
    __le32 status;
    __le16 mcc;
    u8 cap;
    u8 source_id;
    __le16 time;
    __le16 geo_info;
    __le32 n_channels;
    __le32 channels[];
};

🎀 Members 🎀

• status — the status field, lowkey the main character of "did this work or not". see enum iwl_mcc_update_status.
• mcc — the new applied MCC. the fresh one. the upgrade. 💅
• cap — the capabilities for all channels which matches the MCC.
• source_id — where the MCC came from, see iwl_mcc_source.
• time — time elapsed from the MCC test start, and yes it's in units of 30 seconds, so do the math before you @ me 🙈
• geo_info — geographic specific profile information, see enum iwl_geo_information.
• n_channels — number of channels in channels_data.
• channels — the channel control data map, DWORD for each channel. and here's the catch bestie: only the first 16bits are used. only. the first. 16. bits. the rest is just... there. decorative. 💀

like i said. she ate and left no crumbs 👑

ngl bestie, the time unit thing (30 seconds!!) and the "only first 16bits" thing are the two spots where people get humbled. read them twice. i'm not being dramatic, i'm being accurate. 💜

🌸 ok that's the whole page, mwah 💖 — this lil gem lives over in ./drivers/net/wireless/intel/i..., dated October 2026, and it's part of the Kernel API Manual as struct iwl_...date_resp_v3(9). go forth and configure your channels, you gorgeous nerd 🧚‍♀️✨
