STRUCT IWL_MVM_ACS_SURVEY_CHANNEL(9)

💅 struct iwl_mvm_acs_survey_channel(9) — the Kernel API Manual glow-up

okay so you're reading the Kernel API Manual, section 9, and the page is literally called struct iwl_mvm_acs_survey_channel(9). yes bestie the title got chopped in the header, that's just how it's giving — but the whole name is struct iwl_mvm_acs_survey_channel and we're about to know her intimately 🫶

✨ NAME ✨

struct iwl_mvm_acs_survey_channel — per-channel survey information. that's it. that's the whole vibe. one channel's whole little diary of stats 📓

🦋 SYNOPSIS 🦋

struct iwl_mvm_acs_survey_channel {
    u32 time;
    u32 time_busy;
    u32 time_tx;
    u32 time_rx;
    s8 noise;
 };

look at her. five fields. flawless. no notes 💅 (and yes, keep the indentation exactly like that, we don't editorialize other people's source, that's rude)

🎀 Members 🎀

okay let's meet the cast, they're all main characters in their own way:

• time — time in ms the radio was on the channel. the "how long were we even here" field ⏱️
• time_busy — time in ms the channel was sensed busy. the "it was loud and crowded in here" field 😤
• time_tx — time in ms spent transmitting data. the "i was yapping" field 📡
• time_rx — time in ms spent receiving data. the "i was listening, for once" field 👂
• noise — channel noise in dBm. the actual noise level, not the drama level 🌫️

🌸 Description 🌸

Stripped down version of struct survey_info. that's the entire official description and honestly? she's minimal, she's efficient, she's not carrying extra baggage. a lightweight icon 💖

not me pointing out that the channels are all measured in ms for time, time_busy, time_tx, and time_rx, while noise is in dBm — don't mix up your units bestie, that's how you end up in a group chat argument 🔥

so you wanna go down the rabbit hole? say less, here's the whole extended universe:

and that's the whole page, no cap ✨ this came from the source path ./drivers/net/wireless/intel/i... (they truncated it in the footer, which, rude, but okay) and it's dated October 2026, footer title being struct iwl_...rvey_channel(9) — iconic of them to abbreviate. mwah, go forth and survey your channels responsibly 💜🎀
