libnvme(2)

πŸ’– NAME πŸ’–

struct nvme_id_directives β€” the Identify Directive Return Parameters Data Structure, bestie!! it's the lil' blob of memory that holds the answer to "hey, what directives do you support, and which ones are turned ON right now?" πŸŽ€

this is a libnvme(2) API Manual page, so pull up a chair, sip ur iced coffee, and let's get into it 🧚


✨ SYNOPSIS ✨

struct nvme_id_directives {
    __u8 supported[32];
    __u8 enabled[32];
    __u8 rsvd64[4032];
 };

no cap, that's the whole shape of it πŸ‘‘


🌸 Members 🌸

  • supported β€” the bit that tells u whether the Identify directive is supported at all. if it's not supported, like… don't even bother, babes πŸ’…
  • enabled β€” the bit that says the Identify directive is Enabled. supported β‰  enabled, they're two different queens and u need both 😌
  • rsvd64 β€” Reserved. do NOT touch her. she is reserved for a reason, she's not ur business, hands off πŸ™ˆ

ok that's genuinely it, it's a tiny struct, but the way it holds 32 bytes of supported and 32 bytes of enabled and then 4032 bytes of pure reserved silence?? it's giving minimalism ✨

that was the whole struct nvme_id_directives moment, and it absolutely ate πŸ’– this page lives in the API Manual for libnvme(2), and it was all written down back in July 2026 β€” so go forth, check ur directives, and slay πŸ¦‹πŸ’…πŸŒŸ
