💅 libnvme(9) — struct nvme_mi_port_pcie, bestie 💅

okay so this is a page from the API Manual for libnvme, and honestly? it's a little struct that's about to tell you everything you ever wanted to know about PCIe Port Specific Data. no cap, that's the whole vibe. it lives in the libnvme(9) section of the manual, and it's giving "small but mighty." 🦋

✨ NAME ✨

struct nvme_mi_port_pcie — PCIe Port Specific Data

like, this is the struct for PCIe port stuff. main character energy fr fr. 👑

---

🎀 SYNOPSIS 🎀

struct nvme_mi_port_pcie {
    __u8 mps;
    __u8 sls;
    __u8 cls;
    __u8 mlw;
    __u8 nlw;
    __u8 pn;
    __u8 rsvd14[18];
 };

look at her. seven fields, all __u8, one of them a whole array of 18 reserved bytes being iconic and mysterious. we love a struct with structure. 💖

🌸 Members 🌸

here's the breakdown, one by one, no skipping, i promise:

• mps — PCIe Maximum Payload Size. literally the biggest payload she'll carry. 💅
• sls — PCIe Supported Link Speeds Vector. all the link speeds she's down for — it's a whole vector, she's versatile. ✨
• cls — PCIe Current Link Speed. what she's running at right now, bestie. not what she's capable of, what she's doing. 🔥
• mlw — PCIe Maximum Link Width. the widest she can go. dream big. 🌈
• nlw — PCIe Negotiated Link Width. the width everyone actually agreed on. teamwork makes the dream work, or whatever. 🫶
• pn — PCIe Port Number. her number. her ID. her whole identity honestly. 🎀
• rsvd14 — Reserved. not for you. don't touch. this is her space. 🙈

okay real talk: rsvd14 is Reserved, so please don't go writing your little experiments in there. it's reserved for a reason and the reason is not you. 💀

⭐ the cute sign-off ⭐

and that's the page, bestie!! this slice of the libnvme API Manual is dated October 2026, and the whole thing is filed under struct nvme_mi_port_pcie in section libnvme(9). go forth and PCIe responsibly. mwah. 💜🧚‍♀️
