STRUCT MDP_CONFIG(9)

💅 struct mdp_config(9)

okay so bestie, welcome to the Kernel API Manual, section 9 — yes, the big-kid kernel section 🎀. This page is all about struct mdp_config, and it's literally the struct that holds the configuration for your source/destination image. Think of it as the little info card your image walks around with so the hardware knows where it lives, how big it is, and what its vibe (color format) is. 🦋

✨ SYNOPSIS ✨

struct mdp_config {
    int32_t x;
    int32_t y;
    int32_t w;
    int32_t h;
    int32_t w_stride;
    int32_t h_stride;
    int32_t crop_x;
    int32_t crop_y;
    int32_t crop_w;
    int32_t crop_h;
    int32_t format;
 };

that's the whole struct, no cap 💯 — every field is an int32_t, and yes there's a tiny extra space before that closing brace, we keep it exactly as-is because we don't do the original dirty like that 🙈.

🌸 Members (the whole cast, main character energy each one) 🌸

• x — left. that's the horizontal starting point, bestie 📍
• y — top. the vertical starting point, hugging the ceiling 🫶
• w — width. how wide we're going horizontally ✨
• h — height. how tall we're going vertically 📏
• w_stride — bytes in horizontal. the horizontal byte stride, slay 💅
• h_stride — bytes in vertical. the vertical byte stride, also slay 💅
• crop_x — cropped left. left edge of the crop window ✂️
• crop_y — cropped top. top edge of the crop window ✂️
• crop_w — cropped width. how wide the crop is 🎀
• crop_h — cropped height. how tall the crop is 🎀
• format — color format. the color format, aka the ~aesthetic~ of your pixels 🌈

ngl each one of these is just one int32_t, so the struct is basically a cute little lineup of eleven signed 32-bit integers. lowkey iconic 💀

okay that's the whole page, you ate that 💖. this little beauty comes to you from ./drivers/media/platform/media... and it's dated October 2026 — so like, remember the source and the date, mwah, bye bestie! 🫶✨🎀
