💅 libnvme(9) — API Manual

okay bestie, buckle up — this is a page straight out of the libnvme API manual, and it's all about one very specific little enum. yes it's niche. yes it's iconic. let's go 🫶

✨ NAME ✨

enum nvme_lm_migration_recv_fields — the field layout for the Migration Receive command, served fresh with all the shift amounts and masks you could ever want 🎀

🌸 SYNOPSIS 🌸

enum nvme_lm_migration_recv_fields {
    NVME_LM_MIGRATION_RECV_MOS_SHIFT ,
    NVME_LM_MIGRATION_RECV_MOS_MASK ,
    NVME_LM_MIGRATION_RECV_SEL_SHIFT ,
    NVME_LM_MIGRATION_RECV_SEL_MASK ,
    NVME_LM_SEL_GET_CONTROLLER_STATE ,
    NVME_LM_MIGRATION_RECV_UIDX_SHIFT ,
    NVME_LM_MIGRATION_RECV_UIDX_MASK ,
    NVME_LM_GET_CONTROLLER_STATE_CSVI_SHIFT ,
    NVME_LM_GET_CONTROLLER_STATE_CSVI_MASK ,
    NVME_LM_GET_CONTROLLER_STATE_CSUIDXP_SHIFT ,
    NVME_LM_GET_CONTROLLER_STATE_CSUIDXP_MASK ,
    NVME_LM_GET_CONTROLLER_STATE_CSUUIDI_SHIFT ,
    NVME_LM_GET_CONTROLLER_STATE_CSUUIDI_MASK ,
    NVME_LM_GET_CONTROLLER_STATE_CNTLID_SHIFT ,
    NVME_LM_GET_CONTROLLER_STATE_CNTLID_MASK ,
    NVME_LM_GET_CONTROLLER_STATE_CSUP

};

like, that's the whole squad 💜 (yes there's a blank line before the closing brace in the original and we are respecting it, no cap)

👑 Constants 👑

okay so each of these is a constant in the enum, and here's the lowdown on every single one — no skipping, we don't do that here 💅

• NVME_LM_MIGRATION_RECV_MOS_SHIFT — the shift amount you use to set the Management Specific Operation (MOS) field ✨
• NVME_LM_MIGRATION_RECV_MOS_MASK — the mask for setting the MOS field 🎯
• NVME_LM_MIGRATION_RECV_SEL_SHIFT — the shift amount you use to set the Select (SEL) field 🌟
• NVME_LM_MIGRATION_RECV_SEL_MASK — the mask for setting the SEL field 🩷
• NVME_LM_SEL_GET_CONTROLLER_STATE — the Get Controller State select option, literally the main character of this enum 👑
• NVME_LM_MIGRATION_RECV_UIDX_SHIFT — the shift you use to set the UUID Index (UIDX) 🦋
• NVME_LM_MIGRATION_RECV_UIDX_MASK — the mask for setting UIDX 🌈
• NVME_LM_GET_CONTROLLER_STATE_CSVI_SHIFT — the shift amount for setting the Controller State Version Index (CSVI), measured relative to MOS ⭐
• NVME_LM_GET_CONTROLLER_STATE_CSVI_MASK — the mask for setting CSVI relative to MOS 🔥
• NVME_LM_GET_CONTROLLER_STATE_CSUIDXP_SHIFT — the shift amount for setting the Controller State UUID Index Parameter (CSUIDXP) 🧚
• NVME_LM_GET_CONTROLLER_STATE_CSUIDXP_MASK — the mask for setting CSUIDXP 💖
• NVME_LM_GET_CONTROLLER_STATE_CSUUIDI_SHIFT — the shift amount for setting the Controller State UUID Index (CSUUIDI) 🍓
• NVME_LM_GET_CONTROLLER_STATE_CSUUIDI_MASK — the mask for setting CSUUIDI 🌸
• NVME_LM_GET_CONTROLLER_STATE_CNTLID_SHIFT — the shift amount for setting the Controller ID (CNTLID) 💫
• NVME_LM_GET_CONTROLLER_STATE_CNTLID_MASK — the mask for setting CNTLID 🙈
• NVME_LM_GET_CONTROLLER_STATE_CSUP — Controller Suspended, short and sweet, we stan 😭

ngl bestie, these acronyms are a lot — MOS, SEL, UIDX, CSVI, CSUIDXP, CSUUIDI, CNTLID, CSUP — but you got this, fr fr 💀💪

and that's the whole page, you ate that 🫶 this little gem came from the libnvme API manual, dated October 2026, and it's filed under libnvme(9) — the enum nvme_lm_migration_recv_fields says bye and ily 💜✨
