STRUCT VKMS_PLANE_STATE(9)

✨ struct vkms_plane_state(9) ✨

okay bestie, welcome to the struct vkms_plane_state(9) page — it lives in the Kernel API Manual and it's literally the driver-specific plane state, no cap. 🎀

💖 NAME 💖

struct vkms_plane_state — Driver specific plane state 🦋

🌸 SYNOPSIS 🌸

struct vkms_plane_state {
    struct drm_shadow_plane_state base;
    struct vkms_frame_info *frame_info;
    pixel_read_line_t pixel_read_line;
    struct conversion_matrix conversion_matrix;
 };

👑 Members 👑

• base — the base plane state, it's giving foundation, it's giving roots 💅
• frame_info — all the data you need for composing computation ✨
• pixel_read_line — a function that reads a pixel line in this plane. lowkey important: whoever creates a struct vkms_plane_state must make sure this pointer is valid — like fr fr, don't leave it vibing in the void 😭
• conversion_matrix — the matrix used for yuv formats to convert to rgb 🌀 (yes bestie, the math is mathing)
