💖 NAME 💖

struct nvme_fw_download_args — bestie, this is the lil' bundle of arguments you hand over to the NVMe Firmware Download command. that's it, that's the whole job 🫶

This page lives in the libnvme API manual, so if you're the kind of girl who reads kernel-adjacent docs for fun (me, hi, i'm the problem) — welcome home 🌸

✨ SYNOPSIS ✨

okay so here's the whole struct, and like, look at her. gorgeous. no notes 💅

    void *data;
    int args_size;
    int fd;
    __u32 timeout;

    __u32 data_len;
 };

🎀 Members 🎀

every field, one by one, no skipping, we don't do that here 🦋

• result — the command completion result that comes back from CQE dword0. she's the receipts, periodt 📋
• data — the userspace address of the firmware data. like, where the actual bytes are chilling 🍓
• args_size — the size of struct nvme_fw_download_args. yes it's the struct describing its own size, it's giving self-aware icon behavior 💫
• fd — the file descriptor of the nvme device. your lil' golden ticket into the device 🎫
• timeout — timeout in ms. how long you're willing to wait before you're like... girl 😭
• offset — offset in the firmware data. where in the blob we're starting, iykyk 📍
• data_len — length of data in this command, in bytes. how much of the firmware data this particular command is carrying 🔥

ngl bestie, these fields are exactly what the kernel expects — so don't get creative with them, just fill 'em in and let the firmware download do her thing 💖

mwah — that's the whole page, you ate it, no crumbs. this one came straight from the API Manual, filed under struct nvme_fw_download_args in the libnvme(9) collection, and it's dated August 2026. go forth and download that firmware, you absolute main character 👑🌈✨
