💖 libnvme(9) — enum nvme_id_ctrl_cmic 💖

okay bestie, so this is a page from the libnvme API Manual (that's the libnvme(9) situation, iykyk) and it's all about one little enum that tells you what a controller and its NVM subsystem are capable of — specifically the multipath IO + namespace sharing vibes. it's giving "capability flags, but make it a struct" and honestly? iconic. ✨

🌸 NAME 🌸

enum nvme_id_ctrl_cmic — the Controller Multipath IO and Namespace Sharing Capabilities of the controller and NVM subsystem. 💅

like, it's the receipts for what the controller can actually do. no cap.

🦋 SYNOPSIS 🦋

enum nvme_id_ctrl_cmic {
    NVME_CTRL_CMIC_MULTI_PORT ,
    NVME_CTRL_CMIC_MULTI_CTRL ,
    NVME_CTRL_CMIC_MULTI_SRIOV ,
    NVME_CTRL_CMIC_MULTI_ANA_REPORTING

};

literally just four constants, bestie. copy it exactly, don't get creative with it 🫶

🎀 Constants 🎀

okay so here's the whole crew, one by one:

  • NVME_CTRL_CMIC_MULTI_PORT — if this one's set, then the NVM subsystem may contain more than one NVM subsystem port. if it's not set, the NVM subsystem contains only a single NVM subsystem port. one port energy vs. multiverse energy, that's the whole bit. ⭐
  • NVME_CTRL_CMIC_MULTI_CTRL — if set, the NVM subsystem may contain two or more controllers; otherwise the NVM subsystem contains only a single controller. and like, an NVM subsystem that contains multiple controllers may be used by multiple hosts, or may provide multiple paths for a single host. so it's either solo main character or a whole ensemble cast 👑
  • NVME_CTRL_CMIC_MULTI_SRIOV — if set, then the controller is associated with an SR-IOV Virtual Function. otherwise it's associated with a PCI Function or a Fabrics connection. that's the tea 🍓
  • NVME_CTRL_CMIC_MULTI_ANA_REPORTING — if set, then the NVM subsystem supports Asymmetric Namespace Access Reporting. she's reporting for duty, literally 💀
🧚 little vibe check: every one of these is "if set / otherwise" — so don't go assuming anything about a controller until you've actually looked at which bits are set. fr fr.

💜 sign-off 💜

that's the whole page, bestie — no missing details, no skipped constants, we ate and left no crumbs 🌈

this gem dropped in October 2026, it's the enum nvme_id_ctrl_cmic page from the libnvme(9) manual — so go forth, read your capability bits, and stay slay ✨💖
