libnvme(9)

🌸 NAME 🌸

bestie, this is the libnvme API manual (like, the actual libnvme(9) page, hi 👋), and today's main character is enum nvme_mi_port_sdformat — the 2-Wire Port Specific Data - Supported Data Format field, aka SDFORMAT. it's giving "small enum, big responsibilities" fr fr 💅

✨ SYNOPSIS ✨

okay so here's the whole thing, verbatim, no cap:

enum nvme_mi_port_sdformat {
    NVME_MI_PORT_SDFORMAT_BYTE_LEVEL ,
    NVME_MI_PORT_SDFORMAT_512B ,
    NVME_MI_PORT_SDFORMAT_4KIB

};

like yes, there's a space before each comma, and yes there's a blank line before the closing brace — that's just how it is, we don't question the source, we respect the source 🫶

🎀 Constants 🎀

three constants, three vibes, all of them about the NVMe-MI Persistent Data Area. let's get into it 👑

• NVME_MI_PORT_SDFORMAT_BYTE_LEVEL — this one means Byte Level data format of the NVMe-MI Persistent Data Area is supported. byte. level. the smallest unit. the micro-influencer of data formats 🦋
• NVME_MI_PORT_SDFORMAT_512B — this means 512B data format of the NVMe-MI Persistent Data Area is supported. five hundred and twelve bytes of pure, unbothered storage energy 💖
• NVME_MI_PORT_SDFORMAT_4KIB — and this one means 4KiB data format of the NVMe-MI Persistent Data Area is supported. four kibibytes. the main character size. iconic, honestly 🌈

reminder bestie: these are just supported formats — the enum tells you what the Persistent Data Area supports, it doesn't pick one for you. iykyk 😌

and that's the page!! slay 💜 this whole thing is from the libnvme(9) API Manual — October 2026, covering enum nvme_mi_port_sdformat, so if you ever need to cite it, that's the source and the date, periodt ✨🎀
