STRUCT CHANNEL_DETECTOR(9)

💖 struct channel_detector(9) 💖

okay bestie, welcome to struct channel_detector(9) from the Kernel API Manual — yes we're reading kernel docs together, this is our bonding era 🫶

---

🌸 NAME 🌸

struct channel_detector — literally the detector elements for a DFS channel. that's the whole vibe. 💅

---

✨ SYNOPSIS ✨

struct channel_detector {
    struct list_head head;
    u16 freq;
    struct pri_detector *detectors[];
};

look at her. iconic. she's a struct with a flexible array member and she knows it 👑

🎀 Members 🎀

• head — a list_head. that's it, that's the member. it's the list plumbing keeping everything linked up 🦋
• freq — the frequency for this channel detector, in MHz. numbers bestie, we love a unit 📻
• detectors — array of dynamically created detector elements for this freq. dynamic. created at runtime. main character energy fr fr ✨

---

💜 Description 💜

so here's the lore 🍓: channel detectors are required to provide multi-channel DFS detection — like, for example, to support off-channel scanning. iykyk.

and a pattern detector has a list of channels that radar pulses have been reported for in the past. that's the whole deal, no cap 💀
