libnvme(2)

💖 NAME 💖

enum nvme_id_ctrl_mec — bestie, this is the lil enum that holds the flags telling you what the Management Endpoint inside the Controller can actually do ✨. It's literally the type of the &struct nvme_id_ctrl.mec field, so when you see that member in the big identify-controller struct, this is what's living in it. 🎀

---

✨ SYNOPSIS ✨

enum nvme_id_ctrl_mec {
    NVME_CTRL_MEC_SMBUSME ,
    NVME_CTRL_MEC_PCIEME

};

okay so it's giving two constants, that's the whole vibe 👑

---

🌸 Constants 🌸

• NVME_CTRL_MEC_SMBUSME — if this bit is set, then the NVM Subsystem contains a Management Endpoint on an SMBus/I2C port 🔌. yes bestie, a whole management endpoint, just chillin on the SMBus/I2C side.
• NVME_CTRL_MEC_PCIEME — if this bit is set, then the NVM Subsystem contains a Management Endpoint on a PCIe port 🦋. same energy, different bus.

ngl the whole game here is just "is the ME bit set, and on which port" — no cap, that's the entire enum 💅

so yeah, that's the page 🫶 this one came out under the libnvme manual, section 2, and the version we're looking at is dated July 2026 — love that for us, slay, go read some identify controller data 💖✨🎀
