💖 libnvme(9) — the API Manual, but make it make sense 💖

Okay so bestie, we're in the libnvme(9) part of the API manual and today's main character is honestly kind of niche but so valid: the Persistent Event Header Additional Information — Port Identifier Type enum. It's giving "deep lore" but I promise it ate. Let's go 🫶

---

✨ NAME ✨

enum nvme_pel_ehai_pit — Persistent Event Header Additional Information — Port Identifier Type. Yes, that's the whole name, and yes, it's a mouthful. Ngl it's iconic for that. 💅

---

🌸 SYNOPSIS 🌸

enum nvme_pel_ehai_pit {
    NVME_PEL_EHAI_PIT_NOT_REPORTED ,
    NVME_PEL_EHAI_PIT_NSS_PORT ,
    NVME_PEL_EHAI_PIT_NMI_PORT ,
    NVME_PEL_EHAI_PIT_NOT_ASSOCIATED

};

That's the whole squad right there — four constants, no cap, and none of them are getting left out. 🎀

⭐ Constants ⭐

Okay literally one by one, because every single one matters:

• NVME_PEL_EHAI_PIT_NOT_REPORTED — PIT not reported and PELPID does not apply. So like… nobody reported anything, and PELPID? Doesn't even apply. It's giving "don't ask me, I'm not involved" energy. 🙈
• NVME_PEL_EHAI_PIT_NSS_PORT — NVM subsystem port. Cute, straightforward, it's the NVM subsystem port. Slay. ✨
• NVME_PEL_EHAI_PIT_NMI_PORT — NVMe-MI port. Same vibe, different port, and yes they're two different things, bestie, don't mix them up. 🦋
• NVME_PEL_EHAI_PIT_NOT_ASSOCIATED — Event not associated with any port and PELPID does not apply. So the event is just… floating. Unattached. Free spirit. And again PELPID does not apply — that's right, again. 💀

Lowkey the vibe check here is: some ports report, some events just don't belong to a port at all, and sometimes PELPID is simply not part of the conversation. Know the difference, iykyk. 🌈

Alright bestie, that's the whole page — you now know enum nvme_pel_ehai_pit better than most people know themselves. 💜

Sign-off cuteness: send-off from the October 2026 edition of this page, brought to you by enum nvme_pel_ehai_pit and stamped libnvme(9) at the bottom — periodt. 🎀🌸🫶
