libnvme(9)

🦋 NAME 🦋

okay so bestie, welcome to libnvme (yes, that's libnvme(9), the API manual, we're in section 9, hold my iced coffee) 💖

struct nvme_cdp_change_event — the CDP Change Event Data Format, and it's specifically Event Type 0Fh ✨

🌈 SYNOPSIS 🌈

like, here's the whole vibe, literally character for character:

struct nvme_cdp_change_event {
    __u8 ps;
    __u8 perid;
    __u8 rsvd2[10];
    __u8 ped[];
};

look at her. iconic. no notes. 👑

🎀 Members 🎀

okay so let's meet the cast, one by one, main character energy only:

• ps — Personality Status 💅 (yes, the field is literally called personality status, we love a self-aware struct). for the deets, go see enum nvme_cdp_change_event_ps 🫶
• perid — the Personality Identifier of the personality whose settings a Set Features command requested to change 🔥 and fr fr, check enum nvme_personality_identifier for the full list, iykyk
• rsvd2 — Reserved 🙈 (aka not me, don't touch, nothing to see here, it's reserved, periodt)
• ped — Personality Event Data: the data buffer of the Set Features command corresponding to perid, if any ⭐ (the "if any" is doing a lot of heavy lifting here, so don't assume it's always there bestie)

💀 quick vibe check: rsvd2 is reserved, so leave it alone — the spec said what it said, no cap.

and that's the whole page, slay 🌸 — this little cutie came out of libnvme API Manual, dated October 2026, all about struct nvme_cdp_change_event 💖 bye bestie, go read your structs 🧚‍♀️✨
