ENUM DRM_OUTPUT_COLOR_FORMAT(9)

✨ NAME ✨

okay bestie, we're diving into enum drm_output_color_format from the Kernel API Manual — it's literally the Output Color Format enum, and it's the main character of connector color vibes 💖

🌈 SYNOPSIS 🌈

enum drm_output_color_format {
    DRM_OUTPUT_COLOR_FORMAT_RGB444 ,
    DRM_OUTPUT_COLOR_FORMAT_YCBCR444 ,
    DRM_OUTPUT_COLOR_FORMAT_YCBCR422 ,
    DRM_OUTPUT_COLOR_FORMAT_YCBCR420 ,
    DRM_OUTPUT_COLOR_FORMAT_COUNT

};

🎀 Constants 🎀

• DRM_OUTPUT_COLOR_FORMAT_RGB444 — RGB output format. Classic, iconic, the RGB queen 👑
• DRM_OUTPUT_COLOR_FORMAT_YCBCR444 — YCbCr 4:4:4 output format (ie. not subsampled). Full chroma, no skimping, every pixel gets its moment ✨
• DRM_OUTPUT_COLOR_FORMAT_YCBCR422 — YCbCr 4:2:2 output format (ie. with horizontal subsampling). Horizontal subsampling said “we can share” 💅
• DRM_OUTPUT_COLOR_FORMAT_YCBCR420 — YCbCr 4:2:0 output format (ie. with horizontal and vertical subsampling). Both directions are sharing, it’s giving budget-friendly but make it work 🦋
• DRM_OUTPUT_COLOR_FORMAT_COUNT — Number of valid output color format values in this enum. The count, the limit, the final boss of this list 💀

💜 Description 💜

okay so this enum is literally a consolidated color format list supported by connectors. The way that it’s only ever really been used for HDMI and DP so far, so it’s not exhaustive and can be extended to represent other formats in the future. No cap — it’s a living list, bestie 🧚
