💖 libnvme(9) — struct nvme_secondary_ctrl 💖

okay so bestie, this one's from the libnvme API Manual and it's literally just a vibe check on one tiny little struct. no chaos, no flags, no fifty options — just a cute lil' bundle of fields that describes a Secondary Controller Entry ✨ (yes queen, an actual entry in the controller table, we love to see it).

---

🌸 NAME 🌸

struct nvme_secondary_ctrl — the Secondary Controller Entry struct, aka the little data blob that tells you everything about one secondary controller 🎀

---

🦋 SYNOPSIS 🦋

here's the whole thing, character for character, no cap:

struct nvme_secondary_ctrl {
    __le16 scid;
    __le16 pcid;
    __u8 scs;
    __u8 rsvd5[3];
    __le16 vfn;
    __le16 nvq;
    __le16 nvi;
    __u8 rsvd14[18];
 };

look at her. so organized. so little-endian. so __le16-pilled 💅

👑 Members 👑

every field, in order, no skipping, because we do NOT skip the reserved ones (they're reserved, not irrelevant, there's a difference and it's giving nuance 🧚):

• scid — the Secondary Controller Identifier. like, which secondary controller are we even talking about bestie 💁‍♀️
• pcid — the Primary Controller Identifier. the one holding the aux cord, the main character of this relationship 🫶
• scs — the Secondary Controller State. the mood. the status. the current era of this controller 🌈
• rsvd5 — Reserved. don't touch. not yours. it said reserved for a reason 🙈
• vfn — the Virtual Function Number. yes we're doing virtualization today, welcome to the function-verse 💜
• nvq — the Number of VQ Flexible Resources Assigned. how many flexible VQ resources got handed out 🍓
• nvi — the Number of VI Flexible Resources Assigned. and how many flexible VI resources got handed out ✨
• rsvd14 — Reserved. again. still not yours. hands off 🎀

lowkey the reserved fields are the quiet kids in the group chat — they're sitting there taking up space and the spec says leave them alone, so we leave them alone 😭

⭐ that's the whole page ⭐

no SEE ALSO, no exit statuses, no environment variables — she's a short one and honestly? iconic for that. sometimes a manpage is just a struct and a dream 🔥

and that's the tea, bestie — this page came from the libnvme API Manual, and it was dated October 2026, so go forth and read your controller entries with confidence 💅🦋💖
