STRUCT IWL_NVM_GET_INFO_REGULATORY(9)

💜 struct iwl_nvm_get_info_regulatory(9) — the Kernel API Manual, but make it make sense ✨

okay so bestie, welcome to the Kernel API Manual 🎀 and lemme tell you, today's main character is this little struct right here. it's giving "regulatory information" and honestly? she's kinda iconic. let's get into it 💅

---

🌸 NAME 🌸

struct iwl_nvm_get_info_regulatory — regulatory information, periodt. that's her whole job. 🦋

---

✨ SYNOPSIS ✨

here's the glow-up, verbatim, no cap:

struct iwl_nvm_get_info_regulatory {
    __le32 lar_enabled;
    __le32 n_channels;
    __le32 channel_profile[IWL_NUM_CHANNELS_V3];
 };

three fields, all __le32, and one of them is a whole array sized by IWL_NUM_CHANNELS_V3. she said "I contain multitudes" 😭💖

• lar_enabled — this one's the vibe check for LAR: it's LAR enabled. literally what it says on the tin, slay. ⭐
• n_channels — the number of valid channels in the array. so like, not every slot is invited to the party, okay? only n_channels of them are fr fr. 🔥
• channel_profile — the regulatory data of this channel. this is the actual tea ☕ — every valid channel's regulatory info lives right here in this array. 👑

ngl bestie, this page comes straight out of the kernel source tree at ./drivers/net/wireless/intel/i... — the October 2026 edition, and the footer's still repping struct iwl_n...o_regulatory(9) loud and proud. mwah, go read the source, ily 🧚💜
