okay so bestie, welcome to libnvme, section 9 of the manual, and today's main character is a lil struct called nvme_lockdown_cfi_desc. it's giving "small but mighty" ✨ she's the Command and Feature Identifier Descriptor, and honestly? icon behavior.

🎀 NAME

struct nvme_lockdown_cfi_desc — Command and Feature Identifier Descriptor

like… that's her whole job. that's the assignment and she ate 💅

---

✨ SYNOPSIS

struct nvme_lockdown_cfi_desc {
    __u8 cfi;
    __u8 cfia;
 };

two tiny __u8 fields. that's it. no cap, she's lowkey minimal and I'm obsessed 🫶

🌸 Members

⭐ cfi

Command and Feature Identifier: its contents depend on the Contents Selected (CS) and Scope Selected (SS) fields of struct nvme_lockdown_log_enhanced.cfia.

so yeah — what cfi actually means is not fixed, it's contextual, iykyk. she reads the room (specifically, those CS and SS fields) before she tells you anything. main character energy fr fr 💖

⭐ cfia

Command and Feature Identifier Attributes — see enum nvme_lockdown_cfi_desc_cfia for the details 👑

that's your pointer to the enum, bestie. go look at enum nvme_lockdown_cfi_desc_cfia if you wanna know what attributes live in there. I'm not gonna invent them, that's not the vibe 🙈

and that's the whole page, bestie! short and sweet like a little strawberry 🍓 this one shipped in the October 2026 release, and it's living its best life in libnvme(9) — mwah, slay, periodt 💋✨
