libnvme(2)

✨ NAME ✨

bestie… it's enum nvme_lm_migration_send_fields — the Migration Send command fields 💅 this is part of the libnvme API manual, and we're going through every single one of these little constants like it's a group chat catch-up 🫶

🦋 SYNOPSIS 🦋

ok so here's the whole enum, laid out exactly as it lives:

enum nvme_lm_migration_send_fields {

    NVME_LM_MIGRATION_SEND_MOS_MASK ,
    NVME_LM_MIGRATION_SEND_SEL_SHIFT ,
    NVME_LM_MIGRATION_SEND_SEL_MASK ,
    NVME_LM_SEL_SUSPEND ,
    NVME_LM_SEL_RESUME ,
    NVME_LM_SEL_SET_CONTROLLER_STATE ,
    NVME_LM_MIGRATION_SEND_UIDX_SHIFT ,

    NVME_LM_STYPE_SUSPEND_NOTIFICATION ,
    NVME_LM_STYPE_SUSPEND ,
    NVME_LM_SUSPEND_CNTLID_SHIFT ,
    NVME_LM_SUSPEND_CNTLID_MASK ,
    NVME_LM_RESUME_CNTLID_SHIFT ,
    NVME_LM_RESUME_CNTLID_MASK ,
    NVME_LM_SEQIND_SHIFT ,
    NVME_LM_SEQIND_MASK ,

};

thirty constants. no skips. we're eating the whole plate 🍓

💖 Constants 💖

one bullet per icon, no cap:

• NVME_LM_MIGRATION_SEND_MOS_SHIFT — the shift you use to set the Management Operation Specific (MOS) field, periodt 🌸
• NVME_LM_MIGRATION_SEND_MOS_MASK — the mask for setting that MOS field 💫
• NVME_LM_MIGRATION_SEND_SEL_SHIFT — how far you shift to set the Select (SEL) field 👑
• NVME_LM_MIGRATION_SEND_SEL_MASK — the mask for setting SEL 🎀
• NVME_LM_SEL_SUSPEND — Migration Send - Suspend 😴 literally what it says
• NVME_LM_SEL_RESUME — Migration Send - Resume 🌈 back at it again
• NVME_LM_SEL_SET_CONTROLLER_STATE — Migration Send - Set Controller State 🧚 your main character moment for controller state
• NVME_LM_MIGRATION_SEND_UIDX_SHIFT — shift to set the UUID Index (UIDX) 🔥
• NVME_LM_MIGRATION_SEND_UIDX_MASK — mask to set UIDX ✨
• NVME_LM_DUDMQ — Delete User Data Migration Queue 🗑️ bye bestie
• NVME_LM_STYPE_SHIFT — the shift amount for setting Suspend Type (STYPE) 💜
• NVME_LM_STYPE_MASK — mask to set STYPE 🎀
• NVME_LM_STYPE_SUSPEND_NOTIFICATION — Suspend Notification: the specified controller is going to be suspended in the future with a subsequent Migration Send command 🔮 it's giving "heads up, not yet"
• NVME_LM_STYPE_SUSPEND — Suspend: suspend the controller 😭 that's the whole thing
• NVME_LM_SUSPEND_CNTLID_SHIFT — shift amount to set Controller ID (CNTLID) when SEL is Suspend 👀
• NVME_LM_SUSPEND_CNTLID_MASK — mask to set CNTLID with SEL Suspend 🫶
• NVME_LM_RESUME_CNTLID_SHIFT — shift amount to set Controller ID (CNTLID) when SEL is Resume ✨
• NVME_LM_RESUME_CNTLID_MASK — mask to set CNTLID when SEL is Resume 🌟
• NVME_LM_SEQIND_SHIFT — shift amount to set the Sequence Indicator (SEQIND) field, relative to MOS 💅
• NVME_LM_SEQIND_MASK — mask to set the SEQIND field relative to MOS 🎀
• NVME_LM_SEQIND_NOT_FIRST_NOT_LAST — this command is not the first or last of a sequence of two or more Migration Send commands with this management operation, used to transfer the controller state from host to controller 🥪 the middle child fr fr
• NVME_LM_SEQIND_FIRST — this command is the first of a sequence of two or more Migration Send commands 👑
• NVME_LM_SEQIND_LAST — this command is the last command of a sequence of two or more Migration Send commands 🏁
• NVME_LM_SEQIND_ENTIRE — this Migration Send command is the only command and contains the entire controller state for this management operation 🌈 the whole vibe in one packet
• NVME_LM_SET_CONTROLLER_STATE_CSUUIDI_SHIFT — shift amount to set the Controller State UUID Index (CSUUIDI) 💖
• NVME_LM_SET_CONTROLLER_STATE_CSUUIDI_MASK — mask to set CSUUIDI ✨
• NVME_LM_SET_CONTROLLER_STATE_CSVI_SHIFT — shift amount to set the Controller State Version Index (CSVI) 🦋
• NVME_LM_SET_CONTROLLER_STATE_CSVI_MASK — mask to set CSVI 💜
• NVME_LM_SET_CONTROLLER_STATE_CNTLID_SHIFT — shift amount to set Controller ID (CNTLID) when SEL is Set Controller State 🌸
• NVME_LM_SET_CONTROLLER_STATE_CNTLID_MASK — mask to set CNTLID when SEL is Set Controller State 🫶

ok real talk bestie: these are all just shift amounts and masks for wrangling the Migration Send command's fields. nothing dangerous in here, just bit-fiddling 💅
