STRUCT IWL_MEI_NVM(9)

👑 struct iwl_mei_nvm(9) — the Kernel API Manual, bestie edition ✨

okay so real talk, this page lives in the Kernel API Manual, section 9, and it's literally all about struct iwl_mei_nvm — the lil' container we use to pass the NVM over from CSME. it's giving "important messenger" energy and honestly? we're obsessed 🫶

💖 NAME

struct iwl_mei_nvm — the struct used to pass the NVM from CSME. that's it, that's the whole vibe. ✨

---

🦋 SYNOPSIS

struct iwl_mei_nvm {
    u8 hw_addr[ETH_ALEN];
    u8 n_hw_addrs;
    u8 reserved;
    u32 radio_cfg;
    u32 caps;
    u32 nvm_version;
    u32 channels[110];
 };

no cap, that's the whole shape of it. every field counts, every field slays in its own way 💅

---

🌸 MEMBERS

• hw_addr — the MAC address. iconic. the main character of the address world 👑
• n_hw_addrs — how many MAC addresses we're working with. literally just the count, ngl 🎀
• reserved — for alignment. it's not doing much but it's there for a reason and we respect it 🙈
• radio_cfg — the radio configuration. the settings, the setup, the whole situation ⭐
• caps — see enum iwl_mei_nvm_caps. the capabilities live over there, iykyk 🔥
• nvm_version — the version of the NVM. gotta know what generation we're on 💜
• channels — the data for each channel. all of it. and yes, there are 110 of them — she's thorough, she's committed, she ate 🌈

---

💫 DESCRIPTION

so if you ever add a field to this struct, it must correspond to the SAP structure. that's the rule, periodt. no freelancing, no "i'll just sneak one in" — it has to match ✨

fr fr, that constraint is not a suggestion, bestie — new field means you sync it up with the SAP structure. 💀
