ENUM DRM_COLOR_LUT_TESTS(9)

💅 enum drm_color_lut_tests (9)

okay so bestie, welcome to the Kernel API Manual ✨ — this one's from ./include/drm and it's all about the hw-specific LUT tests you can perform. yes, LUT. lookup table. we're doing color science today, periodt 🎀

🌸 NAME 🌸

enum drm_color_lut_tests — the hw-specific LUT tests to perform 🧚

🦋 SYNOPSIS 🦋

enum drm_color_lut_tests {
    DRM_COLOR_LUT_EQUAL_CHANNELS ,
    DRM_COLOR_LUT_NON_DECREASING

};

✨ Constants ✨

• DRM_COLOR_LUT_EQUAL_CHANNELS — this one checks whether the entries of a LUT all have equal values for the red, green, and blue channels 💖 it's literally intended for hardware that only accepts a single value per LUT entry and just assumes that value applies to all three color components. one value, all the vibes, iykyk 🫶
• DRM_COLOR_LUT_NON_DECREASING — this one checks whether the entries of a LUT are always flat or increasing (never decreasing, bestie, never 💀). monotonic queen behavior only 👑

💜 Description 💜

so the drm_color_lut_check function takes a bitmask of the values listed here to determine which tests to apply to a userspace-provided LUT 🌈 bitmask in, vibe check out, no cap.
