wiphy_new_nm(9)

📦 version 7.3.1, in nixpkgs unstable

💫 wiphy_new_nm — like, the Kernel API Manual (section 9) page, bestie ✨

Okay so picture this: you're deep in the Kernel API Manual, section 9, and you hit wiphy_new_nm. Iconic name, honestly. Let me break it down for you 🫶

🌸 NAME 🌸

wiphy_new_nm — create a new wiphy for use with cfg80211

Like, that's the whole job. It makes a wiphy. For cfg80211. Slay 💅

✨ SYNOPSIS ✨

struct wiphy * wiphy_new_nm (const struct cfg80211_ops *ops , int
       sizeof_priv , const char *requested_name );

Three things in, one struct wiphy * out. That's the whole vibe check 🔥

🎀 ARGUMENTS 🎀

  • ops — the configuration operations for this device. Basically the whole personality of your device, handed over as a struct 👑
  • sizeof_priv — the size of the private area to allocate. Yes bestie, you're telling it how much room your own little private stash needs 📦
  • requested_name — you can request a particular name here. NULL is a valid value, and it means use the default phyd naming. So like, no name = default name, no drama 🙈

💜 DESCRIPTION 💜

Create a new wiphy and associate the given operations with it. sizeof_priv bytes are allocated for private use. That's it, that's the whole thing — new wiphy, ops attached, and a private area sized exactly the way you asked for it 🧚

⭐ RETURN ⭐

A pointer to the new wiphy. Fr fr, this pointer must be assigned to each netdev's ieee80211_ptr for proper operation — like, don't just leave it sitting there, that's not the move 😭

Bestie warning: if you don't wire that pointer into each netdev's ieee80211_ptr, proper operation is not happening. Not optional, ngl 💀

✨ SEE ALSO ✨

okay bestie, buckle up 💖 because this is the part where the page just... lists everyone this function knows. like a group chat with 358 members and honestly? every single one of them is relevant. no cap. i'm keeping them all, in order, exactly as written — because leaving one out would be a crime 💅

🎀 the first three, the holy trinity of "go read the intro"

🌸 all the band / rate / cap stuff (the "what can this radio even do" crew)

🦋 Actions and configuration — the whole main-character arc of doing stuff

like genuinely this is the longest clique in the group chat and they're all iconic in their own way ✨

💀 the wiphy lifecycle and all its little work helpers (yes, all of them, i counted)

🧚 Utility functions — the little helpers that lowkey carry everything

🍓 Data path helpers — the ones doing the actual carrying of the packets

👑 Regulatory enforcement infrastructure + the internal regdb bits

💜 the big pile of cfg80211_* notify / report / done functions

⭐ RFkill, vendor commands, test mode — the special-interest besties

🔥 the rest of the saga — connect, roam, mgmt tx/rx, stats, and every notifier

ngl this is the long tail and it goes hard fr fr 😭

and yeah that's the entire friend list 💖 like, all 358 of them, nobody got left on read. the page keeps going tho — more to come, so don't go anywhere 🦋

...and here's the rest of the guest list 💖 ngl it's giving phonebook, but every single one of these has its own page and they're all ride-or-die for the same subsystem, so go say hi:

okay that's the whole thing, bestie — you made it to the end, I'm so proud 😭💜 this page lives in ./include/net, it's dated October 2026, and the page itself is wiphy_new_nm(9). go forth and build something iconic with it ✨🎀
