libnvme(9)

💖 NAME 💖

okay bestie, so like — struct nvme_dev_self_test_args is literally the little argument bundle you hand over when you wanna run the NVMe Device Self Test command. that's it, that's the whole vibe. ✨

---

🌸 SYNOPSIS 🌸

struct nvme_dev_self_test_args {
    __u32 *result;
    int args_size;
    int fd;
    __u32 timeout;
    __u32 nsid;
    enum nvme_dst_stc stc;
 };

🎀 Members 🎀

here's the tea on every single field, no skipping, i would never 🫶

• result — this one's where the command completion result lands, straight from CQE dword0. it's a pointer, so like, it points at the tea. 💅
• args_size — the size of struct nvme_dev_self_test_args. yes it's telling you how big it is. iconic self-awareness honestly. ✨
• fd — file descriptor of the nvme device. your little handle to the actual thing. 🔑
• timeout — timeout in ms. milliseconds bestie, so don't go thinking it's seconds and then get all surprised. 😭
• nsid — Namespace ID to test. that's which namespace is getting the self-test glow-up. 🌈
• stc — Self test code, see enum nvme_dst_stc. go peek at that enum for the actual codes, i'm not gonna make them up for you. 👑

lowkey the whole struct is just "here's my device, here's my namespace, here's the test i want, here's how long i'm willing to wait" and honestly? relatable main character energy. 🌟

and that's the page!! this was the libnvme(9) API Manual situation, dated August 2026, and the page was all about struct nvme_dev_self_test_args the whole time. mwah, love u, go run a self test responsibly. 💖🦋🌸🧚💜
