💖 NAME 💖

struct nvme_mi_vpd_mra — it's giving NVMe MultiRecord Area, bestie 💅

---

✨ SYNOPSIS ✨

okay so here's the whole vibe, literally every field, no skips:

struct nvme_mi_vpd_mra {
    __u8 nmravn;
    __u8 ff;
    __u8 rsvd7[6];
    __u8 i18vpwr;
    __u8 m18vpwr;
    __u8 i33vpwr;
    __u8 m33vpwr;
    __u8 rsvd17;
    __u8 m33vapsr;
    __u8 i5vapsr;
    __u8 m5vapsr;
    __u8 i12vapsr;
    __u8 m12vapsr;
    __u8 mtl;
    __u8 tnvmcap[16];
    __u8 rsvd37[27];
 };

like… she's structured. she's organized. she ate 🍓

🦋 Members 🦋

time for the roll call, every single one, periodt 👑

• nmravn — the NVMe MultiRecord Area Version Number. lowkey the "which version are we even on" field, iconic.
• ff — the Form Factor. what shape is she? this tells u 🌈
• rsvd7 — Reserved. not for u, bestie, hands off 🙈
• i18vpwr — the Initial 1.8 V Power Supply Requirements. the starting 1.8 V energy 💜
• m18vpwr — the Maximum 1.8 V Power Supply Requirements. the maxed-out 1.8 V energy 🔥
• i33vpwr — the Initial 3.3 V Power Supply Requirements. 3.3 V but make it fresh ✨
• m33vpwr — the Maximum 3.3 V Power Supply Requirements. 3.3 V but make it peak 💅
• rsvd17 — Reserved. again. not urs. moving on 🎀
• m33vapsr — the Maximum 3.3 Vi aux Power Supply Requirements. yes the "aux" is doing a lot of work here and yes she's still that girl ⭐
• i5vapsr — the Initial 5 V Power Supply Requirements. the 5 V origin story 🌸
• m5vapsr — the Maximum 5 V Power Supply Requirements. the 5 V final boss 👑
• i12vapsr — the Initial 12 V Power Supply Requirements. twelve whole volts, starting out 🦋
• m12vapsr — the Maximum 12 V Power Supply Requirements. twelve whole volts at full send 😭
• mtl — the Maximum Thermal Load. how much heat she can handle before it's giving meltdown, fr fr 🔥
• tnvmcap — the Total NVM Capacity. the capacity!! the whole thing!! 💖 (she's a __u8 tnvmcap[16];, sixteen bytes of pure capacity lore)
• rsvd37 — Reserved. last one. still not for u. that's just how it is 🫶

no cap bestie, those three rsvd fields are Reserved — like, actually reserved in the spec. don't be the main character who writes into them 🙈
