libnvme(9)

💖 NAME 💖

okay bestie, welcome to the libnvme(9) manual page ✨ this one is all about struct nvme_perf_characteristics, aka the Performance attribute structure — she's giving performance-attribute realness and we're gonna walk through every single member, no skips, no cap 💅

🦋 SYNOPSIS 🦋

here's the exact shape of it, literally:

struct nvme_perf_characteristics {
    union {
      struct nvme_std_perf_attr std_perf[0];
      struct nvme_perf_attr_id_list id_list[0];
      struct nvme_vs_perf_attr vs_perf[0];
      __u8 attr_buf[4096];
    };
 };

look at that anonymous union doing main character energy 😭💖

🌸 Members 🌸

• {unnamed_union} — anonymous 👻 that's literally the description, bestie, and we respect her privacy 🫶
• std_perf — Standard performance attribute ✨
• id_list — Performance attribute identifier list 🧾
• vs_perf — Vendor specific performance attribute 🛠️
• attr_buf — Attribute buffer 🧺

vibe check: every member above is exactly as the page says — std_perf is the standard performance attribute, id_list is the performance attribute identifier list, vs_perf is the vendor specific performance attribute, and attr_buf is the attribute buffer. periodt 💅

and that's the whole page, bestie 🎀 this little libnvme(9) moment was dated October 2026, starring struct nvme_perf_characteristics — slay, iconic, bye 💖🦋✨
