STRUCT LOADER_XFER_QUERY(9)

💅 struct loader_xfer_query(9) — the Kernel API Manual page you didn't know you needed

okay so picture this: you're deep in the Kernel API Manual (yes, that's the manual, we're fancy here) and you land on this little cutie. It's struct loader_xfer_query, and it's the ISHTP firmware loader transfer query packet. That's it. That's the whole vibe. 🎀

Bestie, it's literally just a struct. Two fields. Tiny. Iconic. Let's get into it.

---

✨ SYNOPSIS ✨

here's the whole thing, no cap, copy it exactly:

struct loader_xfer_query {
    __le32 header;
    __le32 image_size;
};

that's the entire serve. two __le32s and a dream. 🦋

🌸 Members 🌸

time for the vibe check on each field, one by one:

• header — the header of the message. that's it, that's the job. it's a header. of the message. 🫶
• image_size — the size of the image. the way it just tells you how big the image is... lowkey doing the most by doing the least. ✨

both of them are __le32, in case you missed it — little-endian 32-bit, periodt.

💜 SEE ALSO 💜

okay so there's a whole friend group and you will be meeting them. first up, the source file they all live in:

• Kernel file ./drivers/hid/intel-ish-hid/ishtp/loader.h

and then the extended squad, in order, no one gets left out (iykyk):

• union loader_msg_header(9)
• struct loader_version(9)
• struct loader_capability(9)
• struct loader_xfer_query_ack(9)
• struct loader_xfer_fragment(9)
• struct loader_xfer_fragment_ack(9)
• struct fragment_dscrpt(9)
• struct loader_xfer_dma_fragment(9)
• struct loader_start(9)
• struct loader_start_ack(9)
• struct ish_firmware_variant(9)
• ishtp_loader_work(9)
• struct ish_global_manifest(9)

fr fr go read them, they're all main character energy in their own way. 🔥

ngl this page is short but she ate. two fields, one file path, thirteen (13) SEE ALSO entries, and absolutely zero notes, bugs, or exit statuses — so don't come for me, there was nothing else to tell you. 💀

and that's the whole page, bestie! 🧚 sign-off time: this one lives over in ./drivers/hid/intel-ish-hid/ishtp, dated October 2026. mwah 💅⭐
