🦋 NAME

okay so bestie, welcome to enum nvme_fid_supported_effects — it's the FID Supported and Effects data structure definitions ✨ This is the libnvme(9) API manual btw, we're deep in the NVMe lore rn 💜

    NVME_FID_SUPPORTED_EFFECTS_NIC ,
    NVME_FID_SUPPORTED_EFFECTS_CCC ,
    NVME_FID_SUPPORTED_EFFECTS_UUID_SEL ,
    NVME_FID_SUPPORTED_EFFECTS_SCOPE_SHIFT ,
    NVME_FID_SUPPORTED_EFFECTS_SCOPE_MASK ,
    NVME_FID_SUPPORTED_EFFECTS_SCOPE_NS ,

    NVME_FID_SUPPORTED_EFFECTS_SCOPE_ENDGRP ,
    NVME_FID_SUPPORTED_EFFECTS_SCOPE_DOMAIN ,
    NVME_FID_SUPPORTED_EFFECTS_SCOPE_NSS ,
    NVME_FID_SUPPORTED_EFFECTS_CDQSCP ,
    NVME_FID_SUPPORTED_EFFECTS_RUHS

};

like yes, that blank line is supposed to be there, she's got main character energy 🎀

✨ Constants

bestie these are the constants and what each one is giving, no cap 👑

• NVME_FID_SUPPORTED_EFFECTS_FSUPP — FID Supported 💖
• NVME_FID_SUPPORTED_EFFECTS_UDCC — User Data Content Change
• NVME_FID_SUPPORTED_EFFECTS_NCC — Namespace Capability Change
• NVME_FID_SUPPORTED_EFFECTS_NIC — Namespace Inventory Change
• NVME_FID_SUPPORTED_EFFECTS_CCC — Controller Capability Change
• NVME_FID_SUPPORTED_EFFECTS_UUID_SEL — UUID Selection Supported 🌸
• NVME_FID_SUPPORTED_EFFECTS_SCOPE_SHIFT — FID Scope Shift
• NVME_FID_SUPPORTED_EFFECTS_SCOPE_MASK — FID Scope Mask
• NVME_FID_SUPPORTED_EFFECTS_SCOPE_NS — Namespace Scope
• NVME_FID_SUPPORTED_EFFECTS_SCOPE_CTRL — Controller Scope
• NVME_FID_SUPPORTED_EFFECTS_SCOPE_NVM_SET — NVM Set Scope
• NVME_FID_SUPPORTED_EFFECTS_SCOPE_ENDGRP — Endurance Group Scope
• NVME_FID_SUPPORTED_EFFECTS_SCOPE_DOMAIN — Domain Scope
• NVME_FID_SUPPORTED_EFFECTS_SCOPE_NSS — NVM Subsystem Scope 🦋
• NVME_FID_SUPPORTED_EFFECTS_CDQSCP — Controller Data Queue
• NVME_FID_SUPPORTED_EFFECTS_RUHS — Reclaim Unit Handle Scope: if set, then modifying the attributes of the feature may impact Reclaim Unit Handles 🔥 (like, heads up bestie, that's a real consequence, not just vibes 👀)

ngl the _RUHS one is the only constant with a whole warning attached, so if you're poking at Reclaim Unit Handles, read it twice fr fr 💀

and that's the whole page, periodt 🫶 this was libnvme(9), from the API Manual, dated October 2026 — go forth and slay your NVMe features, icon 💅🌈
