STRUCT IONIC_FW_DOWNLOAD_CMD(9)

hey bestie 💖 welcome to the Kernel API Manual page for struct ionic_fw_download_cmd(9) — the one and only firmware download command. she’s small, she’s specific, and she’s literally the main character of this header. 👑

💖 NAME 💖

struct ionic_fw_download_cmd — Firmware download command. periodt. That’s the name, that’s the assignment, and we are not doing nickname energy on a kernel struct. ✨

✨ SYNOPSIS ✨

okay so the actual shape is giving exactly this, and we are keeping it character-for-character because kernel code does not want your creative writing era:

struct ionic_fw_download_cmd {
    u8 opcode;
    u8 rsvd[3];
    __le32 offset;
    __le64 addr;
    __le32 length;
};

🎀 Members 🎀

vibe check on the members, one by one:

• opcode — it’s the opcode. the original literally just says opcode again, and honestly? iconic. 🫶
• rsvd — reserved byte(s). hands off, bestie, it’s reserved. 🙈
• offset — offset of the firmware buffer within the full image. 🎯
• addr — dma address of the firmware buffer. 💅
• length — number of valid bytes in the firmware buffer. 🔥
