---

       offset , void *buf );

like. look at her. iconic signature fr 💅

🎀 ARGUMENTS 🎀

• fd — the file descriptor of your nvme device, bestie. she needs her home address. 🏠
• size — the total size of the firmware image you're transferring. the whole thing. no crumbs left behind. ✨
• xfer — the maximum size to send with each partial transfer. think of it as, like, how big each lil bite is 🍓
• offset — the starting offset to send with this firmware download. where in the image we're picking up from, iykyk. 📍
• buf — the address of the buffer containing all or part of the firmware image. all of it, or just a piece — she doesn't judge. 💜

💫 RETURN 💫

so here's the tea: you get the nvme command status if a response was received (check it against enum nvme_status_field), or -1 with errno set otherwise. no in-between, no vibes, just facts. 😭

lowkey important: -1 means she didn't get a response, and errno is the one who tells you why. don't ignore her, she's trying to help. 🫶
