libnvme(2)

💖 NAME 💖

ok so bestie, this is enum nvme_pmrebs — it's giving persistent memory region elasticity buffer size energy ✨ like literally that's the whole vibe of this enum, that's what it is.

🌸 SYNOPSIS 🌸

enum nvme_pmrebs {
    NVME_PMREBS_PMRSZU_SHIFT ,
    NVME_PMREBS_RBB_SHIFT ,
    NVME_PMREBS_PMRWBZ_SHIFT ,
    NVME_PMREBS_PMRSZU_MASK ,
    NVME_PMREBS_RBB_MASK ,
    NVME_PMREBS_PMRWBZ_MASK ,
    NVME_PMREBS_PMRSZU_B ,
    NVME_PMREBS_PMRSZU_1K ,
    NVME_PMREBS_PMRSZU_1M ,
    NVME_PMREBS_PMRSZU_1G

};

like. look at her. ten constants, all of them important, none of them skippable 👑

✨ Constants ✨

okay so these are the constants, and bestie I'm not skipping a single one, we're going all the way down the list fr fr 💅

• NVME_PMREBS_PMRSZU_SHIFT — this is the shift amount you use to get the PMR elasticity buffer size units 🎀
• NVME_PMREBS_RBB_SHIFT — the shift amount that gets you the read bypass behavior 🦋
• NVME_PMREBS_PMRWBZ_SHIFT — shift amount to get the PMR elasticity buffer size base, slay 💖
• NVME_PMREBS_PMRSZU_MASK — the mask that gets you the PMR elasticity buffer size units ✨
• NVME_PMREBS_RBB_MASK — the mask that gets you the read bypass behavior 🌈
• NVME_PMREBS_PMRWBZ_MASK — the mask to get the PMR elasticity buffer size base, periodt 💫
• NVME_PMREBS_PMRSZU_B — Bytes 🍓
• NVME_PMREBS_PMRSZU_1K — 1 KiB 🧚
• NVME_PMREBS_PMRSZU_1M — 1 MiB 🌸
• NVME_PMREBS_PMRSZU_1G — 1 GiB 👑

lowkey a whole unit ladder in one enum. bytes, kibibytes, mebibytes, gibibytes — the PMR elasticity buffer size units really said "we contain multitudes" 😭💜

and that's the whole page bestie, no cap, every single constant accounted for 🫶 this was enum nvme_pmrebs from the libnvme API Manual — page libnvme(2), dated July 2026, and yes the footer literally just repeats libnvme(2) again because she's iconic like that 💅✨
