💅 libnvme(9) — the API Manual, bestie edition

okay so real talk, this is a page from libnvme(9), aka the API Manual, and it's about one very specific little enum. she's small but she's important — she's the one holding all the bit-shifty secrets of the extended LBA format. 🎀

✨ NAME ✨

enum nvme_nvm_id_ns_elbaf — this field indicates the extended LBA format

like. that's her whole job. she indicates the extended LBA format. iconic behavior honestly 💅

---

🌸 SYNOPSIS 🌸

enum nvme_nvm_id_ns_elbaf {
    NVME_NVM_ELBAF_STS_SHIFT ,
    NVME_NVM_ELBAF_STS_MASK ,
    NVME_NVM_ELBAF_PIF_SHIFT ,
    NVME_NVM_ELBAF_PIF_MASK ,
    NVME_NVM_ELBAF_QPIF_SHIFT ,
    NVME_NVM_ELBAF_QPIF_MASK

};

six constants, zero drama, all in a row. she's giving "organized queen" energy fr fr 👑

🦋 Constants 🦋

now the main character moment — let's meet the whole squad, one by one:

• NVME_NVM_ELBAF_STS_SHIFT — the shift you use to get the storage tag size. she slides those bits right into place ✨
• NVME_NVM_ELBAF_STS_MASK — the mask that gets you the storage tag size, which is what you use to figure out the variable-sized storage tag/reference tag fields. lowkey the most useful one here ngl 🫶
• NVME_NVM_ELBAF_PIF_SHIFT — the shift for getting the protection information format. shifting = caring 💖
• NVME_NVM_ELBAF_PIF_MASK — the mask that gets you the protection information format for the extended LBA format. yes, specifically for the extended one. read the label bestie 🔥
• NVME_NVM_ELBAF_QPIF_SHIFT — the shift for getting the Qualified Protection Information Format. capital Q, capital P, capital I, capital F — she's not like the other shifts 💅
• NVME_NVM_ELBAF_QPIF_MASK — the mask that gets you the Qualified Protection Information Format. same deal, but masked. periodt 🌈

ngl the whole page is basically "here's a shift, here's a mask, repeat three times" and honestly? that's the vibe. use the shift, then the mask, and the field is yours 🧚

and that's the tea, bestie 🍓 — this was libnvme(9), the API Manual, dated October 2026, closing out the enum nvme_nvm_id_ns_elbaf page. go shift some bits, you're gonna slay 💜✨
