wiphy_apply...m_regulatory(9)

📦 version 7.3.1, in nixpkgs unstable

✨ NAME ✨

okay so real quick: wiphy_apply_custom_regulatory — apply a custom driver regulatory domain 💅

Welcome to the wiphy_apply...m_regulatory(9) page from the Kernel API Manual, bestie 🫶 this is part 1 and we're getting into it.

🌸 SYNOPSIS 🌸

void wiphy_apply_custom_regulatory (struct wiphy *wiphy , const struct
       ieee80211_regdomain *regd );

🎀 ARGUMENTS 🎀

  • wiphy — the wireless device we want to process the regulatory domain on, no cap 📶
  • regd — the custom regulatory domain to use for this wiphy, periodt ✨

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ Drivers can sometimes have custom regulatory domains which do not apply to a specific country. Drivers can use this to apply such custom regulatory domains. iconic, honestly 👑

This routine must be called prior to wiphy registration — like, before the wiphy gets registered, bestie 👑 don't skip that step.

The custom regulatory domain will be trusted completely and as such previous default channel settings will be disregarded. So yeah, it's the main character here and the old channel settings are getting ignored fr fr 💅

If no rule is found for a channel on the regulatory domain the channel will be disabled 😭 so no rule = channel says bye.

Drivers using this for a wiphy should also set the wiphy flag REGULATORY_CUSTOM_REG or cfg80211 will set it for the wiphy that called this helper. iykyk ⭐

⚠️ must be called prior to wiphy registration — that part is lowkey non-negotiable 🫶

and that's the whole reference list, bestie — 64 links deep and not one skipped 🫶 this little encyclopedia lives in ./include/net, dated October 2026, and that's the wrap on the page. go read some kernel source, ilysm 💖✨🎀
