💖 libnvme(2) — API Manual 💖

okay bestie, welcome to the libnvme manual, page 2 💅 this one's a little enum and she's honestly so underrated. it's giving "tiny but mighty."

---

✨ NAME ✨

enum nvme_pmrswtp — this field indicates the persistent memory region sustained write throughput 🦋

like, literally. that's her whole job. she tells you how fast your persistent memory region can sustain writes, no cap.

---

🌸 SYNOPSIS 🌸

enum nvme_pmrswtp {
    NVME_PMRSWTP_PMRSWTU_SHIFT ,
    NVME_PMRSWTP_PMRSWTV_SHIFT ,
    NVME_PMRSWTP_PMRSWTU_MASK ,
    NVME_PMRSWTP_PMRSWTV_MASK ,
    NVME_PMRSWTP_PMRSWTU_BPS ,
    NVME_PMRSWTP_PMRSWTU_KBPS ,
    NVME_PMRSWTP_PMRSWTU_MBPS ,
    NVME_PMRSWTP_PMRSWTU_GBPS

};

look at her. eight constants, all lined up, minding their business 🎀

👑 Constants 👑

so these are the actual members, and each one is doing a specific lil thing. let's go one by one, bestie, no skipping:

• NVME_PMRSWTP_PMRSWTU_SHIFT — the shift amount to get the PMR sustained write throughput units. it shifts, you get units. iconic behaviour 💅
• NVME_PMRSWTP_PMRSWTV_SHIFT — the shift amount to get the PMR sustained write throughput value itself. the actual throughput. the moment ✨
• NVME_PMRSWTP_PMRSWTU_MASK — a mask to get the PMR sustained write throughput units. masking, but make it purposeful 🫶
• NVME_PMRSWTP_PMRSWTV_MASK — a mask to get the PMR sustained write throughput value. yes, they're a matched set, they're a package deal 😭
• NVME_PMRSWTP_PMRSWTU_BPS — bytes per second 🍓
• NVME_PMRSWTP_PMRSWTU_KBPS — 1 KiB / s 🌈
• NVME_PMRSWTP_PMRSWTU_MBPS — 1 MiB / s 🔥
• NVME_PMRSWTP_PMRSWTU_GBPS — 1 GiB / s 👑

notice the units ladder: B → KiB → MiB → GiB. she climbs, she scales, she serves. that's main character energy fr fr 🌟

heads up bestie: NVME_PMRSWTP_PMRSWTU_KBPS, NVME_PMRSWTP_PMRSWTU_MBPS and NVME_PMRSWTP_PMRSWTU_GBPS are all 1-something per second — one KiB, one MiB, one GiB. don't read them as "kilo/mega/giga" free-floating, they're the binary-flavoured ones 💖

and that's the whole page, you ate it 🎀

this little cutie comes to you from enum nvme_pmrswtp, stamped July 2026, living under the libnvme(2) umbrella — API Manual vibes only. go forth and shift those bits, bestie. iykyk 💜🦋💅
