β¨ regulatory_set_wiphy_regd_sync(9) β¨
okay so this is from the Kernel API Manual, bestie β like, the actual kernel docs, and this one is about setting the regulatory domain for self-managed drivers. it's giving "I handle my own regdom, thanks" energy π
πΈ NAME πΈ
regulatory_set_wiphy_regd_sync β set regdom for self-managed drivers
π SYNOPSIS π
int regulatory_set_wiphy_regd_sync (struct wiphy *wiphy , struct
ieee80211_regdomain *rd );
π¦ ARGUMENTS π¦
wiphyβ the wireless device we want to process the regulatory domain on. like, this is the actual wifi thing we're doing the regdom glow-up for π«Άrdβ the regulatory domain information to use for this wiphy. this is the β¨contentβ¨ of the glow-up.
π DESCRIPTION π
okay so listen: this function requires the RTNL and the wiphy mutex to be held π β no cap, that's a hard requirement, not a suggestion. with those locked down, it applies the new regdomain synchronously to this wiphy. so it's not like "fire and forget", it's "we do it right now, together, bestie" π
for more details see regulatory_set_wiphy_regd. (that's the async-ish sibling, iykyk β go read that one if you want the full lore π)
β RETURN β
0 on success. π
and if it doesn't slay, you get -EINVAL or -EPERM π β those are the two possible failure codes, fr fr.
more parts coming, bestie, don't go anywhere π§
π SEE ALSO π
okay bestie, this is the part where the manpage goes βand here is everyone else in the group chat.β π
itβs a whole extended cinematic universe of (9) pages, and yes, every single one is invited to the function. no skips, no cuts, weβre doing the full roll call:
