STRUCT DC_VALIDATION_STREAM(9)

🌸 NAME 🌸

okay so bestie, this page is all about struct dc_validation_stream(9) from the Kernel API Manual. It is the per-stream surface/stream association for validation — that's the whole assignment, no cap. 💖

✨ SYNOPSIS ✨

Here's the exact shape, bestie:

struct dc_validation_stream {
    struct dc_stream_state *stream;
    struct dc_plane_state *plane_states[MAX_SURFACES];
    uint8_t plane_count;
};

🎀 Members 🎀

• stream — stream state properties ✨
• plane_states — surface state 🦋
• plane_count — total of active planes, periodt 💯
