nvme_init_get_log(9)

📦 version 3.2, in arch rolling

💫 nvme_init_get_log — the libnvme API manual, bestie edition 💫

Okay so real talk: this is a page from the libnvme API manual, and today's main character is nvme_init_get_log(9). Yes, that's the manpage section 9 — kernel/API territory, we love to see it. 🎀

✨ NAME ✨

nvme_init_get_log — literally just initializes a passthru command for the NVMe Admin Get Log. That's it. That's the whole vibe. No cap. 💅

🌸 SYNOPSIS 🌸

void nvme_init_get_log (struct libnvme_passthru_cmd *cmd , __u32 nsid ,
       enum nvme_cmd_get_log_lid lid , enum nvme_csi csi , void *data , __u32
       len );

Notice it returns void, so like… she's not giving you a return value. She's giving you setup. Set the stage, queen. 👑

🦋 ARGUMENTS 🦋

Every single one of these matters, so let's go through them one by one, together, hand in hand 🫶

  • cmd — the passthru command to use. This is the thing getting initialized, the canvas, the main character of the function. ✨
  • nsid — namespace identifier, if applicable. Note the "if applicable" — sometimes there just isn't a namespace in the picture, and that's fine, we're not judging. 🌈
  • lid — the Log Page Identifier. Head over to enum nvme_cmd_get_log_lid for the full menu of known values. iykyk. 🔥
  • csi — the command set identifier. Same deal: check enum nvme_csi for the known values, because that's where the real answers live. 💜
  • data — the user space destination address where the data is gonna get transferred. Your buffer, your business. 🍓
  • len — length of the user buffer you just handed over, in bytes, and it's the thing holding the log data. Keep it honest, bestie. 💀
Heads up, no surprises here: every value is passed straight through, and the page doesn't promise you any side effects or error returns beyond what's written. Don't go inventing behaviour that isn't on the page — that's not the vibe check we're doing today. 🙈

So yeah, that's the whole page — small but iconic, an absolute legend in her own right. 💖 And listen, this beauty is dated October 2026, brought to you courtesy of the libnvme API manual and this exact nvme_init_get_log page — go off, team, you ate. 👑💅🌸
