STRUCT PD_CHUNKED_EXT_MESSAGE_DATA(9)

🌸 struct pd_chunked_ext_message_data(9) 🌸

okay so this is a page from the Kernel API Manual, and bestie, we're about to learn exactly what a PD chunked extended message looks like when it's out there on the wire 💅 — like, its literal raw wire form, no glow-up, no filter. it's giving "struct reveal" and honestly? iconic.

---

✨ NAME ✨

struct pd_chunked_ext_message_data — the PD chunked extended message data as seen on wire 🦋

---

🎀 SYNOPSIS 🎀

struct pd_chunked_ext_message_data {
    __le16 header;
    u8 data[PD_EXT_MAX_CHUNK_DATA];
 };

that's it. that's the whole struct. two members and a dream 🫶

---

💖 Members 💖

• header — the PD extended message header ✨ (it's a __le16, so little-endian, no cap)
• data — the PD extended message data 🌈 (an array of u8, sized PD_EXT_MAX_CHUNK_DATA — the max, the limit, the moment)

---

👑 SEE ALSO 👑

• the kernel file ./include/linux/usb/pd.h — go read it, iykyk 📖
• struct pd_message(9)
• struct sink_caps_ext_msg(9)
• BSDO(9)

---

ngl, the whole vibe here is "the chunked ext message on the wire" — that's the entire lore, and we're obsessed 💀

okay bestie that's the whole page, no crumbs left 🌸 — it lives in ./include/linux/usb, dated October 2026, and it's literally titled struct pd_ch...message_data(9) because the header line got its own little abbreviated moment. slay, periodt 💜 🎀 ⭐
