NVME_INIT_GET_LOG_CREATE_TELEMETRY_HOST_MCDA-LIBNVME3(2)

👑 nvme_init_get_log_create_telemetry_host_mcda — the libnvme API manual, but make it make sense 💅

okay so bestie, welcome to the libnvme API manual 🎀 — yes, that's the whole vibe, we're in library-land now, and this particular page is about one very specific little function that sets up a telemetry log command for you. No cap, it's niche, but it's iconic niche. Let's go ✨

✨ NAME ✨

nvme_init_get_log_create_telemetry_host_mcda — Initialize passthru command for Create Telemetry Host-Initiated 🦋

Like, say the whole name out loud once, it's giving "I have a lot of siblings and my parents ran out of ideas" 😭 but it does exactly what it says on the tin.

---

🌸 SYNOPSIS 🌸

void nvme_init_get_log_create_telemetry_host_mcda (struct
libnvme_passthru_cmd *cmd , enum nvme_telemetry_da mcda , struct
nvme_telemetry_log *log );

Three arguments in, and nothing comes back out (void, she's a doer not a returner 💁‍♀️). Main character energy fr fr.

---

💖 ARGUMENTS 💖

• cmd — the passthru command you want to use 🫶 like, hand her the buffer, she'll fill it in.
• mcda — Maximum Created Data Area 😌 yes that's the real name, it's an enum nvme_telemetry_da, very official, very demure.
• log — the userspace address of the log payload 📦 that's where the good stuff lands.

---

⭐ DESCRIPTION ⭐

So what does she actually do? She initializes the passthru command buffer for the Get Log command 🎀 — and she's very specific about it:

• the LID value is NVME_LOG_LID_TELEMETRY_HOST 🔥
• the LSP value is NVME_LOG_TELEM_HOST_LSP_CREATE 💅

That's the whole bit. She sets those up in your ${cmd} buffer and then hands the mic back to you. periodt. 👑

ngl, this one's a builder, not a caller — she preps the command, you still have to actually send it. Don't be out here expecting her to do the ioctl for you, bestie 😭
