STRUCT MIPI_DSI_PACKET(9)

💅 struct mipi_dsi_packet 💅

okay so bestie, welcome to the Kernel API Manual ✨ and today's main character is struct mipi_dsi_packet — it literally represents a MIPI DSI packet in protocol format, no cap 🎀

---

✨ NAME ✨

struct mipi_dsi_packet — the struct that represents a MIPI DSI packet in protocol format 🦋

---

🌸 SYNOPSIS 🌸

struct mipi_dsi_packet {
    size_t size;
    u8 header[4];
    size_t payload_length;
    const u8 *payload;
 };

like, that's the whole vibe. four fields, all iconic, all doing their job 💅

---

👑 Members 👑

• size — the size of the packet, in bytes. that's it, that's the field 🫶
• header — the four bytes that make up the header 💖 and if you're wondering what's in those four lil bytes: it's the Data ID, the Word Count or Packet Data, and the ECC. the whole squad in one array 🔥
• payload_length — literally just the number of bytes in the payload ✨
• payload — a pointer to a buffer containing the payload, if any 🌈 note the "if any" bestie, sometimes there's no payload and that's valid 💀
