libnvme(9)

💅 libnvme(9) — the API manual, bestie edition

okay so picture this: you're deep in libnvme and you hit this one enum. It's the enum nvme_personality_mrstt, and it's literally the "how hard do I have to hit this thing to make it start over" list. MRSTT = Minimum Required Reset Type, i.e. the ✨personality properties✨ of a thing and the least amount of reset it needs to get its life together. Slay.

🎀 NAME

enum nvme_personality_mrstt — Personality Properties - Minimum Required Reset Type (MRSTT). That's it, that's the whole vibe: each value tells you the smallest reset that'll actually do the job. No cap.

🌸 SYNOPSIS

enum nvme_personality_mrstt {
    NVME_PERSONALITY_MRSTT_NONE ,
    NVME_PERSONALITY_MRSTT_CTRL_RESET ,
    NVME_PERSONALITY_MRSTT_LIMITED_CTRL_RESET ,
    NVME_PERSONALITY_MRSTT_NVM_SUBSYSTEM_RESET ,
    NVME_PERSONALITY_MRSTT_POWER_CYCLE

};

✨ Constants

bestie, here's the whole lineup, from "chill, do nothing" all the way to "unplug it from the wall". Ranked, obvs. 👑

• NVME_PERSONALITY_MRSTT_NONE — No reset required 💤 like, none. Zero. Nothing to do, go touch grass.
• NVME_PERSONALITY_MRSTT_CTRL_RESET — Controller Level Reset required 🌪 the controller needs a lil shake-up, that's the minimum.
• NVME_PERSONALITY_MRSTT_LIMITED_CTRL_RESET — Controller Level Reset other than one initiated by a Controller Reset required 🙈 yes that's the actual wording, and yes it's giving "reset, but not that kind of reset". Note the Limited in the name — it's a specific flavour of Controller Level Reset, iykyk.
• NVME_PERSONALITY_MRSTT_NVM_SUBSYSTEM_RESET — NVM Subsystem Reset required 🌀 bigger guns now, we're resetting the whole NVM subsystem, main character energy.
• NVME_PERSONALITY_MRSTT_POWER_CYCLE — Main power cycle required 💀 the final boss. Cut the main power and bring it back. Iconic, dramatic, and honestly a little scary.

fr fr: don't mix these up — the whole point is the minimum. If you go harder than the value says you needed, that's on you, bestie. 🙈
