💖 libnvme(9) — API Manual 💖

okay bestie, so this is a page straight out of the libnvme API manual (section 9, we're fancy like that ✨), and it's literally just one struct. One. Gorgeous. Little. Struct. It's giving "small but mighty" and honestly? Obsessed. 🫶

✨ NAME ✨

struct nvme_fdp_event — the FDP Event struct, no cap 💅

🌸 SYNOPSIS 🌸

here's the whole vibe, character for character, don't touch a thing:

struct nvme_fdp_event {
    __u8 type;
    __u8 flags;
    __le16 pid;
    struct nvme_timestamp ts;
    __le32 nsid;
    __u8 type_specific[16];
    __le16 rgid;
    __u8 ruhid;
    __u8 rsvd35[5];
    __u8 vs[24];
 };

look at her. eleven fields. every single one accounted for. slay 🔥

🎀 Members 🎀

this is the part where we go field by field, and yes, we're doing all of them, because skipping members is not the move 🙈

• type — the Event Type (it's an enum nvme_fdp_event_type, iykyk) 👑
• flags — the Event Flags (this one's an enum nvme_fdp_event_flags, periodt) ⭐
• pid — the Placement Identifier, cute and __le16-sized 💖
• ts — the Timestamp, and it's a struct nvme_timestamp so you know it's keeping track of time fr fr 🕰️
• nsid — the Namespace Identifier — say hi to your namespace bestie 🌈
• type_specific — the Event Type Specific Information, __u8 type_specific[16], sixteen whole bytes of "it depends, bestie" energy 🦋
• rgid — the Reclaim Group Identifier 🌸
• ruhid — the Reclaim Unit Handle Identifier, one single __u8, tiny icon 💅
• rsvd35 — Reserved. __u8 rsvd35[5]. it's reserved, we don't touch it, we just respect it 🙈
• vs — Vendor Specific, __u8 vs[24] — the "your vendor, your rules" corner of the struct 🧚

lowkey reminder: the reserved field is reserved and the vendor specific field is vendor specific. that's the whole assignment. don't be out here repurposing things, bestie 😭

and that's the page!! every field, every type, every array size, all present and accounted for 💜 this was struct nvme_fdp_event in the libnvme API Manual, section 9, dated October 2026 — mwah, go forth and parse those FDP events, main character energy only 👑✨
