NVME_GET_LOG_MEDIA_UNIT_STAT(2)

💖 nvme_get_log_media_unit_stat — let's get that Media Unit Status bestie 💖

okay so real talk, this one is from the libnvme API manual and it is exactly what it sounds like: you're reaching into your NVMe device and asking it to spill the tea on its Media Unit Status. no cap. it's giving "tell me everything, I'm nosy" energy and honestly? iconic. 🎀

✨ NAME ✨

nvme_get_log_media_unit_stat — Retrieve Media Unit Status 🦋

like yes, that is literally the whole job. it goes and gets the media unit status log. she's focused. she knows her assignment. periodt. 💅

---

🌸 SYNOPSIS 🌸

int nvme_get_log_media_unit_stat (int fd , __u16 domid , struct
nvme_media_unit_stat_log *mus );

three little args and a whole lot of power. copy it exactly, don't freestyle it, I am begging you. 🙈

---

💜 ARGUMENTS 💜

• fd — the file descriptor of your nvme device. this is your lil VIP pass, your backstage wristband, the thing that says "yes I am allowed to talk to this drive." no fd, no vibes. 🔑
• domid — Domain Identifier selection, if supported. note that "if supported" bestie, because not every device is gonna have domains to pick from. if yours isn't into it, don't push. 💀
• mus — User address to store the Media Unit statistics log. this is the lil basket you hand over so the kernel has somewhere to drop the log. you gotta bring your own memory, she's not providing one. 🧚

---

🔥 RETURN 🔥

so here's what you get back:

• The nvme command status if a response was received (see enum nvme_status_field) 👑
• or -1 with errno set otherwise 😭

that's it. that's the whole deal. response came back? you get a status, go look it up in enum nvme_status_field. no response? -1, and errno is standing right there holding the explanation. check errno, always, fr fr. ⭐

---

lowkey reminder: enum nvme_status_field is where the actual meaning lives, so don't just stare at the number and guess. go read the enum. iykyk. 💖

and that's the page babes 🌈 — every detail intact, every vibe immaculate. this little gem comes to you from the libnvme API manual, dated July 2026. go get that media unit status, you main character. 🫶✨
