💅 libnvme(9) — okay bestie, let's talk struct tcg_l0_datastore

So this is a page straight out of the libnvme API Manual (yes, the libnvme(9) one, section 9, we're fancy like that ✨) and it's all about one very specific little struct. Buckle up, it's giving "niche but iconic" 🎀

---

🌸 NAME 🌸

struct tcg_l0_datastore — the Additional DataStore Tables feature, and its feature code is 0x0202 in case anyone asks (they will, bestie, write it down 🖊️)

---

✨ SYNOPSIS ✨

Here's the whole vibe, character for character, no notes:

struct tcg_l0_datastore {
    __be16 rsvd0;
    __be16 max_tables;
    __be32 max_table_size;
    __be32 table_alignment;
 };

Not me obsessing over those __be types — that's big-endian energy and we respect it 🫶

---

👑 Members 👑

• rsvd0 — reserved. It's just sitting there, minding its own business, holding space for the future 💜
• max_tables — the maximum number of DataStore tables. That's the ceiling, periodt.
• max_table_size — the maximum total size of DataStore tables. Total, as in all of them together, don't get it twisted 😭
• table_alignment — the DataStore table size alignment. Everything's gotta line up pretty, like a well-organized grid 🌈

🦋 Description 🦋

This is the TCG Opal SSC Feature Set: Additional DataStore Tables 1.00, and the good stuff lives in section 4.2.1 — go read it, iykyk 📖✨

Fr fr though: this is a spec-mirroring struct, so treat those field names and sizes as load-bearing. Don't go renaming anything, the vibes are load-bearing too 💀

---

And that's the whole page, bestie — every field, every byte, every reserved little corner of it. You ate that 🍓

🌸 sign-off time 🌸 — this was struct tcg_l0_datastore, from the libnvme(9) API Manual, dated October 2026. Go forth and slay your DataStore tables 👑💖
