libnvme(2)

💖 NAME 💖

enum nvme_ctrl_metadata_type — Controller Metadata Element Types 🎀 (it's from the API Manual, bestie, and it lives in section 2 of the libnvme docs, so you know it's the real deal)

✨ SYNOPSIS ✨

okay so here's the whole enum, and yes we're gonna list every single one of them, no skips:

enum nvme_ctrl_metadata_type {
    NVME_CTRL_METADATA_OS_CTRL_NAME ,
    NVME_CTRL_METADATA_OS_DRIVER_NAME ,
    NVME_CTRL_METADATA_OS_DRIVER_VER ,
    NVME_CTRL_METADATA_PRE_BOOT_CTRL_NAME ,
    NVME_CTRL_METADATA_PRE_BOOT_DRIVER_NAME ,
    NVME_CTRL_METADATA_PRE_BOOT_DRIVER_VER ,
    NVME_CTRL_METADATA_SYS_PROC_MODEL ,
    NVME_CTRL_METADATA_CHIPSET_DRV_NAME ,

🦋 Constants 🦋

every member of this enum, one by one, with what it actually means 💅

• NVME_CTRL_METADATA_OS_CTRL_NAME — the name of the controller as the operating system sees it ✨
• NVME_CTRL_METADATA_OS_DRIVER_NAME — the driver's name, but in the operating system this time 🫶
• NVME_CTRL_METADATA_OS_DRIVER_VER — the driver's version, operating-system flavored 🍓
• NVME_CTRL_METADATA_PRE_BOOT_CTRL_NAME — the controller's name in the pre-boot environment 👀 yes, they get their own namespace
• NVME_CTRL_METADATA_PRE_BOOT_DRIVER_NAME — the driver's name in the pre-boot environment 🌸
• NVME_CTRL_METADATA_PRE_BOOT_DRIVER_VER — the driver's version in the pre-boot environment 💜
• NVME_CTRL_METADATA_SYS_PROC_MODEL — the model of the processor 😭 the literal CPU, iconic
• NVME_CTRL_METADATA_CHIPSET_DRV_NAME — chipset driver name 🔥
• NVME_CTRL_METADATA_CHIPSET_DRV_VERSION — chipset driver version 🔥
• NVME_CTRL_METADATA_OS_NAME_AND_BUILD — the operating system's name and build, together, as one 💫
• NVME_CTRL_METADATA_SYS_PROD_NAME — system product name ⭐
• NVME_CTRL_METADATA_FIRMWARE_VERSION — the host firmware version — e.g UEFI — like yes bestie, that firmware 🧚
• NVME_CTRL_METADATA_OS_DRIVER_FILENAME — the operating system driver's filename 🎀
• NVME_CTRL_METADATA_DISPLAY_DRV_NAME — display driver name 🌈
• NVME_CTRL_METADATA_DISPLAY_DRV_VERSION — display driver version 🌈
• NVME_CTRL_METADATA_HOST_DET_FAIL_REC — failure record 💀 (that's the whole description, she's mysterious, we respect it)

quick vibe check: these don't have hidden defaults or secret side effects hiding in this page — they're just enum members, one per metadata element. What you see is what you get, fr fr.
