libnvme(2)

💖 NAME 💖

okay so bestie, gather round — this is struct nvme_mi_read_nvm_ss_info, aka the NVM Subsystem Information Data Structure from the libnvme API manual. she's the little glow-up data blob that tells you how many ports your NVM subsystem has and which NVMe-MI version it's serving. iconic behavior tbh 🎀

---

✨ SYNOPSIS ✨

here's the whole fit, no notes, exactly as she ships:

struct nvme_mi_read_nvm_ss_info {
    __u8 nump;
    __u8 mjr;
    __u8 mnr;
    __u8 rsvd3[29];
 };

look at her. four fields. one of them is literally just 29 bytes of vibes and silence. we love a reserved queen 🫶

🌸 Members 🌸

• nump — Number of Ports. literally just how many ports this NVM subsystem has. count 'em 💅
• mjr — NVMe-MI Major Version Number. the big-number part of the NVMe-MI version. main character digit fr.
• mnr — NVMe-MI Minor Version Number. the lil' follow-up digit. she's serving backup dancer energy, but she matters ✨
• rsvd3 — Reserved. twenty-nine bytes of do not touch. no cap, just leave her alone. reserved means reserved, bestie 🙈

not me pointing at rsvd3 and being like "that's just padding" — it's Reserved, capital R, and the spec said what it said. do not go poking around in there, it's giving undefined behavior 💀
