💖 libnvme — struct nbft_hfi 💖

okay bestie, welcome to the libnvme API manual, section 2 — yes, the whole thing. sit down, grab a boba 🧋, because today's main character is a lil struct called nbft_hfi, and she is literally the Host Fabric Interface (HFI) Descriptor, straight out of Figure 11. 👑

---

✨ NAME ✨

struct nbft_hfi — the Host Fabric Interface (HFI) Descriptor (Figure 11). no cap, that's the whole name. iconic of her. 💅

---

🌸 SYNOPSIS 🌸

struct nbft_hfi {
    __u8 structure_id;
    __u8 index;
    __u8 flags;
    __u8 trtype;
    __u8 reserved1[12];
    struct nbft_heap_obj trinfo_obj;
    __u8 reserved2[10];
 };

look at that layout. the way she's just sitting there, all packed and little 🥺. beautiful. perfect. no notes.

🎀 Members 🎀

bestie this is the part where we go field by field, because every single one of them matters, fr fr. 🔥

• structure_id — the Structure ID. this field shall be set to 3h (i.e., Host Fabric Interface Descriptor; #NBFT_DESC_HFI). it's giving "hi, i'm the HFI descriptor, no need to guess." 👋
• index — the HFI Descriptor Index. this one tells you the number of this HFI Descriptor inside the Host Fabric Interface Descriptor List. like a seat number but make it fabric. 🔢
• flags — the HFI Descriptor Flags. for the deets, go look at enum nbft_hfi_flags. go on, she's waiting. 🚩
• trtype — the HFI Transport Type. check enum nbft_trtype for the full tea. 🚚
• reserved1 — Reserved. that's it. that's the whole personality. do not perceive her. 🙈
• trinfo_obj — the HFI Transport Info Descriptor Heap Object Reference</half>... I mean HFI Transport Info Descriptor Heap Object Reference 💖. if this field is set to a non-zero value, then this field indicates the location and size of a heap object containing a HFI Transport Info. zero = she said nothing. non-zero = she's pointing you at a whole heap object. slay. 📍
• reserved2 — Reserved. again. ten whole bytes of minding her own business. respect. ✨

ngl, the reserved fields are lowkey the most chill members in this entire struct. they're just there. existing. living their truth. 🦋
