STRUCT IWL_LARI_CONFIG_CHANGE_CMD(9)

💖 NAME 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this page is all about struct iwl_lari_config_change_cmd, and its whole job is: change LARI configuration. that's it, that's the vibe 🎀

✨ SYNOPSIS ✨

no cap, here's the literal struct, exactly as it lives:

struct iwl_lari_config_change_cmd {
    __le32 config_bitmap;
    __le32 oem_uhb_allow_bitmap;
    __le32 oem_11ax_allow_bitmap;
    __le32 oem_unii4_allow_bitmap;
    __le32 chan_state_active_bitmap;
    __le32 force_disable_channels_bitmap;
    __le32 edt_bitmap;
    __le32 oem_320mhz_allow_bitmap;
    __le32 oem_11be_allow_bitmap;
    __le32 oem_11bn_allow_bitmap;
    __le32 oem_unii9_enable;
    struct iwl_bios_config_hdr bios_hdr;
    __le32 oem_uhb_allow_extension_bitmap;
    struct iwl_bios_config_hdr bios_wcpe_hdr;
    __le32 wcpe_bitmap;
    struct iwl_bios_config_hdr bios_wbem_hdr;
    __le32 reserved[10];
    __le32 oem_supported_dsm_bitmap;
};

🦋 MEMBERS 🦋

okay this is the part where we meet the whole cast, main character energy only 💅

• config_bitmap — the bitmap of the config commands. every single bit triggers a different predefined FW config operation 👑
• oem_uhb_allow_bitmap — bitmap of UHB enabled MCC sets 🫶
• oem_11ax_allow_bitmap — bitmap of 11ax allowed MCCs. there are two bits per country: one of them says whether to override, and the other one says the value to use. two-for-one deal, we love that for us ✨
• oem_unii4_allow_bitmap — bitmap of unii4 allowed MCCs. same energy: two bits per country, one says whether to override, the other says allow/disallow unii4 channels 🌸
• chan_state_active_bitmap — bitmap to enable different bands per country or region. each bit = a country or region, plus a band to activate, all according to the BIOS definitions. bit 0 - 6: supported 🌈
• force_disable_channels_bitmap — bitmap of disabled bands/channels. each bit represents a set of channels in a specific band that should be disabled. yes this one is literally the "nope, off" list 🙈
• edt_bitmap — bitmap of the energy detection threshold table. it disables/enables the EDT optimization method for different band 💀
• oem_320mhz_allow_bitmap — 320Mhz bandwidth enablement bitmap per MCC. bit0: enable 320Mhz in Japan 🇯🇵 · bit1: enable 320Mhz in South Korea 🇰🇷 · bit 2 - 31: reserved 🔥
• oem_11be_allow_bitmap — bitmap of 11be allowed MCCs. no need to mask out the unsupported bits (iykyk). bit0: enable 11be in China(CB/CN) · bit1: enable 11be in South Korea · bit 2 - 31: reserved ⭐
• oem_11bn_allow_bitmap — bitmap of 11bn allowed MCCs. the firmware expects to get the data from the BIOS 👀
• oem_unii9_enable — UNII-9 enablement as read from the BIOS 💜
• bios_hdr — bios config header 🎀
• oem_uhb_allow_extension_bitmap — DSM Function 4 data, as an extension of the UHB enabled MCC sets 🧚
• bios_wcpe_hdr — puncturing config header 🍓
• wcpe_bitmap — bitmap of puncturing enablement per MCC 💫
• bios_wbem_hdr — 320 MHz per-MCC WBEM config header 🌸
• reserved — reserved. it's giving "nothing to see here" 🫥
• oem_supported_dsm_bitmap — DSM function 0 bitmap, describing the supported DSM function indices 👑

okay that's the whole page bestie, you ate that. go read your BIOS bitmaps responsibly 🫶

and for the cute sign-off: this lil beauty comes from the kernel source at ./drivers/net/wireless/intel/i..., dated October 2026, and it's living its best life as struct iwl_...g_change_cmd(9) in the Kernel API Manual 💖✨🎀
