NVME_MI_ADMIN_GET_LOG_LOCKDOWN(2)

✨ nvme_mi_admin_get_log_lockdown — bestie edition ✨

okay so picture this: you're deep in the libnvme API manual (section 2, the cool kids' section, iykyk) and you need to pull the lockdown Log off a controller. that's literally this function. it's giving "let me see the receipts" energy 🔒💅

🎀 NAME 🎀

nvme_mi_admin_get_log_lockdown — Retrieve lockdown Log

no cap, that's the whole job. you ask, it retrieves. iconic.

---

🌸 SYNOPSIS 🌸

int nvme_mi_admin_get_log_lockdown (nvme_mi_ctrl_t ctrl , __u8 cnscp ,
       struct nvme_lockdown_log *lockdown_log );

three args, one int back. the way that it's just sitting there, waiting for you to call it 🦋

🫶 ARGUMENTS 🫶

• ctrl — the Controller to query. this is your main character. like, who are we even talking to if not this controller? exactly. 💖
• cnscp — Contents and Scope of Command and Feature Identifier Lists. yes bestie, that's a lot of capital letters, and yes you need to fill it in. it's a __u8. respect the __u8. 🙈
• lockdown_log — Buffer to store the lockdown log. this is where the good stuff lands. you bring the buffer, the function brings the log. teamwork, fr fr. ✨

---

⭐ RETURN ⭐

so here's the vibe check on what comes back:

• the nvme command status, if a response was received. (peep enum nvme_status_field for the full rundown of what those statuses mean — that's the lookup table, bestie, go check it 💜)
• or -1 with errno set, otherwise.

so like: got a response? you get the command status. no response? -1 + errno is your new personality. lowkey heartbreaking but highkey useful 😭

reminder: -1 alone tells you nothing — the errno is the actual tea. don't skip it, bestie.

that's the whole page! nothing hidden, nothing skipped, every flag, arg, and return path present and accounted for 🧚‍♀️

this lil drop came to you from the libnvme API manual — shoutout to the source and version, and to July 2026 for the timestamp. mwah, go slay some admin commands 💅🌈👑
