🎀 Constants 🎀

okay so here's the whole cast of characters, one by one, no skips, no cuts 💅

• NBFT_DESC_HEADER — the Header: literally an ACPI structure header but with some extra NBFT-specific info sprinkled on top. it's giving ✨foundation✨
• NBFT_DESC_CONTROL — the Control Descriptor: this one tells you where the host, HFI, SSNS, security, and discovery descriptors are all hanging out. it's the group chat admin of the whole thing 🫶
• NBFT_DESC_HOST — the Host Descriptor: just host information. that's it, that's the vibe 🌱
• NBFT_DESC_HFI — the HFI Descriptor: an indexable table of HFI Descriptors, one for every single fabric interface on the host. one per interface, no favoritism 🔥
• NBFT_DESC_SSNS — the Subsystem Namespace Descriptor</Subsystem>: an indexable table of SSNS Descriptors. we love an indexable table, periodt 👑
• NBFT_DESC_SECURITY — the Security Descriptor: an indexable table of Security descriptors. keeping it safe, keeping it locked 🔒 (metaphorically, obviously)
• NBFT_DESC_DISCOVERY — the Discovery Descriptor: an indexable table of Discovery Descriptors. finders keepers 🦋
• NBFT_DESC_HFI_TRINFO — the HFI Transport Descriptor: this one gets pointed at by an HFI Descriptor, and it corresponds to a specific transport for a single HFI. so like, one HFI, one transport, main character energy 💜
• NBFT_DESC_RESERVED_8 — Reserved. nothing to see here bestie, move along 🙈
• NBFT_DESC_SSNS_EXT_INFO — the SSNS Extended Info Descriptor: an SSNS Descriptor points at this one if required. only when necessary, it's not doing overtime for free 😭

fr fr, that's the whole enum — all ten of them, and that's on Figure 5 💀✨

and that's a wrap, bestie 🎀 this page came from the libnvme(2) API Manual, dated July 2026, and it lives under the libnvme(2) name — enum nbft_desc_type, signature slay, ~~no cap~~ actually cap, it's fully accurate 💖🫶
