libnvme(9)

💖 libnvme(9) 💖

okay so bestie, we need to talk about libnvme(9) — it's the API manual for libnvme, and today we're doing a deep dive on this one enum, and honestly? it's giving "I contain multitudes" and I'm obsessed.

✨ NAME ✨

enum nvme_mi_mi_opcode — the operation code for supported NVMe-MI commands, periodt 💅

🦋 SYNOPSIS 🦋

enum nvme_mi_mi_opcode {
    nvme_mi_mi_opcode_mi_data_read ,
    nvme_mi_mi_opcode_subsys_health_status_poll ,
    nvme_mi_mi_opcode_ctrl_health_status_poll ,
    nvme_mi_mi_opcode_configuration_set ,
    nvme_mi_mi_opcode_configuration_get ,
    nvme_mi_mi_opcode_vpd_read ,
    nvme_mi_mi_opcode_vpd_write ,
    nvme_mi_mi_opcode_reset ,
    nvme_mi_mi_opcode_ses_recv ,
    nvme_mi_mi_opcode_ses_send ,
    nvme_mi_mi_opcode_meb_read ,
    nvme_mi_mi_opcode_meb_write ,
    nvme_mi_mi_opcode_shutdown ,
    nvme_mi_mi_opcode_pda_read ,
    nvme_mi_mi_opcode_pda_write ,
    nvme_mi_mi_opcode_pda_write_zeroes

};

like, look at that list. sixteen whole opcodes. main character energy from top to bottom, no cap. 🎀

🌸 Constants 🌸

each one of these is a literal vibe, so let's go through them one by one, bestie:

• nvme_mi_mi_opcode_mi_data_read — Read NVMe-MI Data Structure. it literally reads the NVMe-MI data structure, slay.
• nvme_mi_mi_opcode_subsys_health_status_poll — Subsystem Health Status Poll. checking on the subsystem's health, like a good friend should 🫶
• nvme_mi_mi_opcode_ctrl_health_status_poll — Controller Health Status Poll. same energy but for the controller, iconic.
• nvme_mi_mi_opcode_configuration_set — MI Configuration Set. setting the MI configuration, we love a decisive moment ✨
• nvme_mi_mi_opcode_configuration_get — MI Configuration Get. getting the MI configuration, the sequel we deserved.
• nvme_mi_mi_opcode_vpd_read — VPD Read. reading that VPD, periodt.
• nvme_mi_mi_opcode_vpd_write — VPD Write. writing that VPD, the way that it just works 💅
• nvme_mi_mi_opcode_reset — Reset. it resets. dramatic? maybe. necessary? absolutely. 🔥
• nvme_mi_mi_opcode_ses_recv — SES Receive. receiving SES, iykyk.
• nvme_mi_mi_opcode_ses_send — SES Send. sending SES, the other half of the duo 🌈
• nvme_mi_mi_opcode_meb_read — Management Endpoint Buffer Read. reading from the Management Endpoint Buffer, no notes.
• nvme_mi_mi_opcode_meb_write — Management Endpoint Buffer Write. writing to the Management Endpoint Buffer, ate and left no crumbs 🍓
• nvme_mi_mi_opcode_shutdown — Shutdown. it shuts it down. literally the main character of endings 💀
• nvme_mi_mi_opcode_pda_read — NVMe-MI PDA Read. reading the NVMe-MI PDA, lowkey essential.
• nvme_mi_mi_opcode_pda_write — NVMe-MI PDA Write. writing the NVMe-MI PDA, highkey essential too.
• nvme_mi_mi_opcode_pda_write_zeroes — NVMe-MI PDA Write Zeroes. writing zeroes to the NVMe-MI PDA, and honestly? zeroes have never been so iconic 🌟

okay that's the whole enum, bestie, every single opcode accounted for, nothing skipped, we ate 🍽️💖

so like, that's the page!! this was enum nvme_mi_mi_opcode from the libnvme(9) API Manual, dated October 2026 — go off, you're gonna do amazing with these opcodes, ily, bye 🧚✨🎀
