libnvme(2)

💖 NAME 💖

enum nvme_nvm_id_ns_elbaf — bestie, this field literally indicates the extended LBA format ✨

Ok so we're in the libnvme API manual, which is the whole vibe of this page. This is your girl's guide to one tiny enum and the mask constants that live inside it. No cap, it's short but it matters.

---

🌸 SYNOPSIS 🌸

enum nvme_nvm_id_ns_elbaf {
    NVME_NVM_ELBAF_STS_MASK ,
    NVME_NVM_ELBAF_PIF_MASK ,
    NVME_NVM_ELBAF_QPIF_MASK

};

Like… three constants. That's the whole cast. Main character energy, honestly. 🫶

✨ Constants ✨

• NVME_NVM_ELBAF_STS_MASK — this is the mask you use to grab the storage tag size, and that size is what tells you how big the variable-sized storage tag / reference tag fields are gonna be. 💅
• NVME_NVM_ELBAF_PIF_MASK — the mask that gets you the protection information format for the extended LBA format. Protection info? Iconic. Protective. We love her. 🎀
• NVME_NVM_ELBAF_QPIF_MASK — and this one is the mask that gets you the Qualified Protection Information Format. Yes, qualified. She has credentials. 👑

ngl bestie, masks are just bit math doing its little thing — but these three are the only ones on this page, so that's the whole tea 🍓
