libnvme(9)

💅 NAME 💅

okay so bestie, welcome to enum nvme_cmd_format_pi — it's literally the Format NVM - Protection Information enum, and yes it lives in the libnvme(9) API manual, we're fancy now 🎀

✨ SYNOPSIS ✨

enum nvme_cmd_format_pi {
    NVME_FORMAT_PI_DISABLE ,
    NVME_FORMAT_PI_TYPE1 ,
    NVME_FORMAT_PI_TYPE2 ,
    NVME_FORMAT_PI_TYPE3

};

that's the whole vibe, no cap 🫶

🌸 Constants 🌸

these are the four constants and honestly there are exactly four, so let's give each one its moment 👑

• NVME_FORMAT_PI_DISABLE — protection information is not enabled. it's giving "we're just raw-dogging the data, no PI today" 🙈
• NVME_FORMAT_PI_TYPE1 — protection information is enabled, and it's Type 1. slay 💅
• NVME_FORMAT_PI_TYPE2 — protection information is enabled, Type 2 this time. iconic, different flavor 🦋
• NVME_FORMAT_PI_TYPE3 — protection information is enabled, Type 3, the last one, main character energy fr fr ⭐

ngl bestie, the descriptions above are the entire story — the manpage does not elaborate on what Type 1 vs Type 2 vs Type 3 actually do, so don't come for me, i'm just the messenger 😭 iykyk, go read the NVMe spec for the deep lore 📚
