STRUCT PDS_CORE_FW_DOWNLOAD_CMD(9)

💖 struct pds_core_fw_download_cmd(9) — like, the Firmware Download Command ✨

okay so bestie, welcome to the Kernel API Manual 🎀 and today's main character is struct pds_core_fw_download_cmd — literally the firmware download command, no cap. she's giving "here's where the firmware bytes go" energy and honestly? we're obsessed 💅

---

🌸 NAME 🌸

struct pds_core_fw_download_cmd — the Firmware download command 💖 (yes that's the whole name, she's a struct, she contains multitudes)

---

✨ SYNOPSIS ✨

okay so here's the whole glow-up, copied exactly because we do not fumble the code 🔥

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

look at her. five fields. immaculate vibes. let's get into it 🫶

---

🦋 Members 🦋

• opcode — the opcode, bestie. that's it, that's the field 💜 she tells everyone what kind of command this is.
• rsvd — Word boundary padding 🌸 literally just there to keep things lined up all pretty. filler queen, but a necessary filler queen.
• offset — the offset of the firmware buffer within the full image ⭐ so like, where this chunk sits in the big picture. iykyk.
• addr — the DMA address of the firmware buffer 💫 the actual address, direct memory access style.
• length — the number of valid bytes in the firmware buffer ✨ how much of this buffer is actually, you know, real. the rest is giving decoration.

fr fr, don't sleep on rsvd — it's padding and it matters, it keeps the word boundaries correct. respect her 🎀

that's the whole page bestie, you ate that 💅

🧚 cute little sign-off: this came from ./include/linux/pds, dated October 2026, and it's all about struct pds_...download_cmd(9) — go forth and download that firmware, queen 👑💖
