💖 libnvme(9) — the API Manual, bestie edition 💖

okay so this one's from the libnvme API Manual and it's literally just one struct, but she's iconic so we're gonna give her the full main-character treatment ✨

---

🌸 NAME 🌸

struct nvme_persistent_event_entry — Persistent Event 🎀

like, she's an entry. she's persistent. she's an event. the name ate and left no crumbs 💅

---

✨ SYNOPSIS ✨

here's the whole vibe, copied exactly so you can trust me fr fr:

struct nvme_persistent_event_entry {
    __u8 etype;
    __u8 etype_rev;
    __u8 ehl;
    __u8 ehai;
    __le16 cntlid;
    __le64 ets;
    __le16 pelpid;
    __u8 rsvd16[4];
    __le16 vsil;
    __le16 el;
 };

no cap, that's the entire struct. she's giving organized, she's giving field-annotated, she's giving "I know my types" 🦋

okay bestie, field by field, let's get into it 👑

• etype — Event Type 🌈 — the actual what kind of event is this of it all.
• etype_rev — Event Type Revision — the version tag for that event type, iykyk.
• ehl — Event Header Length — how long the header is, in case you were wondering.
• ehai — Event Header Additional Info — the extra info that lives up in the header ✨
• cntlid — Controller Identifier — which controller this is, her little ID badge 💳
• ets — Event Timestamp — when it happened. time is a construct but timestamps are real ⏰
• pelpid — Port Identifier — the port's ID, periodt 🎀
• rsvd16 — Reserved — respectfully reserved, do not touch, she's saving that seat 🙈
• vsil — Vendor Specific Information Length — how much vendor-specific info there is, measured in length obviously 💅
• el — Event Length — and finally, the length of the event itself. full circle, we love a closer 🔥

lowkey important: rsvd16 is Reserved — so like, leave her alone, don't be writing your little values in there 😭

okay that's the whole page, no filler, every field accounted for, nothing skipped 💜

sign-off time 🧚: this little beauty is the struct nvme_persistent_event_entry page from the libnvme API Manual, dated October 2026 — so yeah, she's fresh, she's timestamped, she's slaying into the future ⭐💖

now go forth and parse those persistent events, bestie. you got this 🌈👑
