STRUCT BRCMF_CFG80211_WOWL(9)

🌸 struct brcmf_cfg80211_wowl(9) — Kernel API Manual, bestie edition 🌸

okay so this is a page straight outta the Kernel API Manual, and it's about struct brcmf_cfg80211_wowl — which is literally just the lil info-holder for "wowl" stuff. wowl = wake-on-wireless-lan energy, and this struct is the group chat where all that info gets passed around 🫶

✨ NAME ✨

struct brcmf_cfg80211_wowl — wowl related information. that's it, that's the whole vibe 💅

---

🎀 SYNOPSIS 🎀

here's the struct in all its glory, copy-pasted exactly because we do NOT mess with source code in this house:

struct brcmf_cfg80211_wowl {
    bool active;
    u32 pre_pmmode;
    struct cfg80211_wowlan_nd_match *nd;
    struct cfg80211_wowlan_nd_info *nd_info;
    wait_queue_head_t nd_data_wait;
    bool nd_data_completed;
    bool nd_enabled;
 };

---

💖 Members 💖

every field, none skipped, let's go:

• active — gets set when you suspend, and cleared when you resume. so it's basically the "am i asleep rn" bool, main character of the suspend/resume arc 😴
• pre_pmmode — the firmware PM mode it was rockin' right when it entered suspend. a u32, no cap.
• nd — net dectect data. (yes "dectect", that's how the original spells it, don't come for me 😭) it's a struct cfg80211_wowlan_nd_match *.
• nd_info — helper struct to pass to cfg80211. a struct cfg80211_wowlan_nd_info *, doing the little handoff 🫱
• nd_data_wait — wait queue to sync net detect data. type is wait_queue_head_t, and it is literally there to keep things in sync, iconic behavior.
• nd_data_completed — completion for net detect data. a bool, keeping track of whether the net detect data is done-done ✅
• nd_enabled — net detect enabled. another bool, the on/off switch of the whole net-detect situation.
