💖 libnvme(2) — bestie edition 💖

okay so this is a page from the libnvme API manual, and we're talking about enum nvme_cmic. yes it's a mouthful, yes it's important, stay with me 🫶

---

🌸 NAME 🌸

enum nvme_cmic — this field is literally the controller's multi-path I/O and NS sharing capabilities. that's the whole vibe. it tells you what your controller can do when multiple paths / multiple namespaces are in the mix ✨

---

🎀 SYNOPSIS 🎀

here's the whole enum, no crumbs left behind:

enum nvme_cmic {
    NVME_CMIC_MULTI_PORT_SHIFT ,
    NVME_CMIC_MULTI_CTRL_SHIFT ,
    NVME_CMIC_MULTI_SRIOV_SHIFT ,
    NVME_CMIC_MULTI_ANA_SHIFT ,
    NVME_CMIC_MULTI_RSVD_SHIFT ,
    NVME_CMIC_MULTI_PORT_MASK ,
    NVME_CMIC_MULTI_CTRL_MASK ,
    NVME_CMIC_MULTI_SRIOV_MASK ,
    NVME_CMIC_MULTI_ANA_MASK ,
    NVME_CMIC_MULTI_RSVD_MASK

};

💅 Constants 💅

so we've got two flavours here, bestie: shift amounts and masks. shifts slide the bits over, masks grab 'em out. iconic duo, fr fr.

• NVME_CMIC_MULTI_PORT_SHIFT — shift amount to get the NVM subsystem port 🚪
• NVME_CMIC_MULTI_CTRL_SHIFT — shift amount to get the controllers 🎛️
• NVME_CMIC_MULTI_SRIOV_SHIFT — shift amount to get the SR-IOV virtual function 🌈
• NVME_CMIC_MULTI_ANA_SHIFT — shift amount to get the asymmetric namespace access reporting 👀
• NVME_CMIC_MULTI_RSVD_SHIFT — shift amount to get the reserved 💀
• NVME_CMIC_MULTI_PORT_MASK — mask to get the NVM subsystem port 🚪
• NVME_CMIC_MULTI_CTRL_MASK — mask to get the controllers 🎛️
• NVME_CMIC_MULTI_SRIOV_MASK — mask to get the SR-IOV virtual function 🌈
• NVME_CMIC_MULTI_ANA_MASK — mask to get the asymmetric namespace access reporting 👀
• NVME_CMIC_MULTI_RSVD_MASK — mask to get the reserved 💀

not me listing all ten of these like a playlist. anyway. shifts to move, masks to grab. that's the whole assignment 💖
