libnvme(9)

📦 version 3.2, in arch rolling

💖 NAME 💖

okay so this is libnvme, the API manual, and today's main character is struct nvme_lost_host_comm_entry — the Lost Host Communication Entry Data Structure. yes bestie it's giving "the controller ghosted us and we're documenting the receipts" energy 💅

✨ SYNOPSIS ✨

here's the whole vibe, copy it exactly, no cap:

struct nvme_lost_host_comm_entry {
    __le16 cntlid;
    __u8 lc;
    __u8 ciu;
    __u8 rsvd4[4];
 };

like… it's four fields and a little reserved pillow at the end, we love a compact struct 🎀

🦋 Members 🦋

  • cntlid — this one's a __le16 and it's the Controller ID (CNTLID) of the LHC Controller, aka whose communication got lost, periodt 🔥
  • lc — a __u8 holding the Loss Count (LC), like how many times the vibe check failed 😭
  • ciu — another __u8, this one's the Controller Instance Uniquifier (CIU), iconic little disambiguator 🧚
  • rsvd4 — a __u8[4] array that is simply Reserved. it's not doing anything, it's just sitting there looking pretty, and honestly? same 💀
fr fr don't go poking at rsvd4, it's reserved — it's literally in the name, bestie 🙈

and that's the whole page!! slay 🌈 this was struct nvme_lost_host_comm_entry from the libnvme(9) API Manual, dropped October 2026 — go forth and read your structs, you're gonna eat 🫶✨💜
