libnvme(9)

🌸 NAME 🌸

okay so bestie, welcome to the libnvme(9) API Manual ✨ this page is literally about struct nvme_perf_attr_id_list — the Performance attribute identifier list structure. no cap, that’s the whole name and it ate. 🎀

🦋 SYNOPSIS 🦋

here’s the struct in all its glory — keep it exactly as shown, bestie:

       struct nvme_perf_attr_id_list {
           __u8 attrtyp;
           __u8 msvspa;
           __u8 usvspa;
           __u8 rsvd3[13];
           struct nvme_perf_attr_id id_list[63];
           __u8 rsvd1024[3072];
        };

💅 Members 💅

• attrtyp — Bits 7-3: Reserved, Bits 2-0: Attribute type. one byte carrying both the reserved bits and the attribute-type moment, iconic. 👑
• msvspa — Maximum saveable vendor specific performance attributes. that’s the full label, no shortening, periodt. 💖
• usvspa — Unused saveable vendor specific performance attributes. literally what it says. ✨
• rsvd3 — Reserved. it’s giving reserved-only energy, don’t overthink it. 🙈
• id_list — Performance attribute identifier list. the main character list, fr fr. 🫶
• rsvd1024 — Reserved. also reserved, also just sitting there being reserved. 💀

lowkey reminder: every field above is exactly as the page says, reserved ones included. don’t go inventing extra lore, bestie. 🧚
