libnvme(2)

💖 libnvme — the API manual, bestie edition 💖

okay so we're deep in libnvme(2) territory rn, and today's main character is a lil enum that's all about telling you which parts of a diagnostic report actually mean something. no cap. let's get into it 🦋

---

✨ NAME ✨

enum nvme_st_valid_diag_info — Valid Diagnostic Information

like… it's the vibe check for your diagnostic info fields. each one's either "yeah this is valid" or "nah bestie, ignore it" 💅

---

🌸 SYNOPSIS 🌸

enum nvme_st_valid_diag_info {
    NVME_ST_VALID_DIAG_INFO_NSID ,
    NVME_ST_VALID_DIAG_INFO_FLBA ,
    NVME_ST_VALID_DIAG_INFO_SCT ,
    NVME_ST_VALID_DIAG_INFO_SC

};

look at her. four little constants, all serving. peak minimalist queen behavior 👑

🎀 Constants 🎀

• NVME_ST_VALID_DIAG_INFO_NSID — NSID Valid: if this one's set, then the contents of the Namespace Identifier field are valid. fr fr, that field is legit, no notes 💖
• NVME_ST_VALID_DIAG_INFO_FLBA — FLBA Valid: if this one's set, then the contents of the Failing LBA field are valid. so if you see it, that Failing LBA is giving real information, periodt 🔥
• NVME_ST_VALID_DIAG_INFO_SCT — SCT Valid: if this one's set, then the contents of the Status Code Type field are valid. yup yup, Status Code Type is trustworthy when this flag shows up ✨
• NVME_ST_VALID_DIAG_INFO_SC — SC Valid: if this one's set, then the contents of the Status Code field are valid. status code said "I'm real" and honestly? we believe her 🫶

---

lowkey the whole point: every one of these is a "if set, then valid" situation. if it's not set, that field is not valid. don't be out here reading invalid fields and calling it data, bestie 😭

---

and that's the whole enum!! four constants, four little "yes this field is valid" green flags 💚
