nvme_set_property(2)

💖 nvme_set_property — a libnvme API manual moment 💖

okay bestie, welcome to the group chat. this is the nvme_set_property(2) page from the libnvme API manual, and yes we're gonna read it together, no skipping 💅

---

✨ NAME ✨

nvme_set_property — bestie, this is how you set a controller property. that's it. that's the whole vibe. 🎀

---

✨ SYNOPSIS ✨

int nvme_set_property (struct nvme_set_property_args *args );

periodt. one function, one argument, immaculate energy. ✨

---

✨ ARGUMENTS ✨

• args — this is a struct nvme_set_property_args argument structure 🫶 like literally it's the args struct, she's carrying the whole operation on her back, main character energy fr fr.

---

✨ DESCRIPTION ✨

okay so listen up because this part actually matters 🔥

This is an NVMe-over-Fabrics specific command, and ngl it is not applicable to PCIe. so if you're on PCIe bestie, this is not your moment, step aside 🙈

And the way these properties align to the PCI MMIO controller registers? iconic. literally matching, one-to-one, slay. 💜

---

✨ RETURN ✨

So what do you get back? Let's talk:

• the nvme command status — but only if a response was received (peep enum nvme_status_field for the deets 👀)
• or -1 with errno set — for every other situation

basically: response came through, you get status. no response, you get -1 and errno is telling the whole story 😭

---

lowkey a reminder that -1 is not a vibe, it's an error, so check that errno before you spiral 🫶
