ENUM IWL_REG_CAPA_FLAGS_V1(9)

✨ enum iwl_reg_capa_flags_v1(9) ✨

okay so this is a page from the Kernel API Manual — yes, the Kernel API Manual, bestie, we're literally in the big leagues now 💅 — and it's all about enum iwl_reg_capa_flags_v1, which is not a vibe, it's a whole enum. Let's get into it 🫶

💖 NAME 💖

enum iwl_reg_capa_flags_v1 — the global flags that get applied to the whole regulatory domain. like, the entire thing, no exceptions, no "just this one channel" shenanigans. periodt 🌍

🌈 SYNOPSIS 🌈

enum iwl_reg_capa_flags_v1 {
    REG_CAPA_V1_BF_CCD_LOW_BAND ,
    REG_CAPA_V1_BF_CCD_HIGH_BAND ,
    REG_CAPA_V1_160MHZ_ALLOWED ,
    REG_CAPA_V1_80MHZ_ALLOWED ,
    REG_CAPA_V1_MCS_8_ALLOWED ,
    REG_CAPA_V1_MCS_9_ALLOWED ,
    REG_CAPA_V1_40MHZ_FORBIDDEN ,
    REG_CAPA_V1_DC_HIGH_ENABLED ,
    REG_CAPA_V1_11AX_DISABLED

};

look at her. nine constants. iconic. 👑

🎀 Constants 🎀

okay bestie, here's the full lineup, each one gets its own moment ⭐

• REG_CAPA_V1_BF_CCD_LOW_BAND — Beam-forming or Cyclic Delay Diversity in the 2.4Ghz band is allowed. both options, allowed, slay 📶
• REG_CAPA_V1_BF_CCD_HIGH_BAND — Beam-forming or Cyclic Delay Diversity in the 5Ghz band is allowed. same deal, higher band, still allowed 🔥
• REG_CAPA_V1_160MHZ_ALLOWED — an 11ac channel with a width of 160Mhz is allowed for this regulatory domain — but heads up, it's valid only in 5Ghz 👀
• REG_CAPA_V1_80MHZ_ALLOWED — an 11ac channel with a width of 80Mhz is allowed for this regulatory domain — also valid only in 5Ghz, no cap 🦋
• REG_CAPA_V1_MCS_8_ALLOWED — 11ac with MCS 8 is allowed. that's it, that's the flag 💜
• REG_CAPA_V1_MCS_9_ALLOWED — 11ac with MCS 9 is allowed. one better, still allowed, we love consistency 🌸
• REG_CAPA_V1_40MHZ_FORBIDDEN — an 11n channel with a width of 40Mhz is forbidden for this regulatory domain — and yep, valid only in 5Ghz. forbidden is forbidden, don't test it 🙈
• REG_CAPA_V1_DC_HIGH_ENABLED — DC HIGH allowed. short, sweet, enabled 💫
• REG_CAPA_V1_11AX_DISABLED — 11ax is forbidden for this regulatory domain. nope. not today. not in this domain 💀

the kernel file lives at ./drivers/net/wireless/intel/iwlwifi/iwl-nvm-parse.c — go read the source, iykyk 📖

and if you wanna meet the rest of the family, say hi to enum iwl_reg_capa_flags_v2(9), enum iwl_reg_capa_flags_v5(9), and enum iwl_reg_capa_flags_v6(9). it's a whole squad 🫶

ngl bestie, if you're poking at regulatory domain flags, take the forbidden ones seriously — REG_CAPA_V1_40MHZ_FORBIDDEN and REG_CAPA_V1_11AX_DISABLED mean forbidden and forbidden, no wiggle room 💅

and that's the whole page! 🎀 source is ./drivers/net/wireless/intel/i... and it's dated October 2026, which — yeah — is giving time traveler energy ⏰💖 bye bestie, go configure responsibly 🦋
