💖 NAME 💖

Hey bestie, welcome to the libnvme(9) API Manual 💅. This page is all about struct nvme_mi_read_port_info — the Port Information Data Structure. That’s the whole vibe: port info, struct edition. ✨

🦋 SYNOPSIS 🦋

Here’s the struct in all its main-character glory:

       struct nvme_mi_read_port_info {
           __u8 portt;
           __u8 prtcap;
           __le16 mmctptus;
           __le32 meb;
           union {
             struct nvme_mi_port_pcie pcie;
             struct nvme_mi_port_smb smb;
           };
        };

🎀 Members 🎀

• portt — Port Type. Literally telling you the type of the port, no cap.
• prtcap — Port Capabilities, so peek at enum nvme_mi_port_prtcap for the details. iykyk 👀
• mmctptus — Maximum MCTP Transmission Unit Size. Big name, big responsibility.
• meb — Management Endpoint Buffer Size. It’s giving buffer size, management endpoint style.
• {unnamed_union} — anonymous. Yes bestie, this union is unnamed — mysterious, lowkey iconic, and just there.
• pcie — PCIe Port Specific Data. All the PCIe-specific data lives right here.
• smb — SMBus Port Specific Data. And the SMBus-specific data is right here too.

Bye bestie 🫶 — sign-off from October 2026, struct nvme_mi_read_port_info, libnvme(9) API Manual. Periodt. 💋
