Struct ColorPipeline 

pub struct ColorPipeline {
    pub has_degamma_lut: bool,
    pub has_ctm: bool,
    pub has_hdr_mult: bool,
    pub degamma_lut_size: u32,
}

Per-plane color pipeline support (pre-blend CMS).

When all three are present the plane can apply per-layer EOTF inversion, gamut conversion, and an SDR-luminance multiplier before the kernel blends in linear light — the only correct way to mix HDR and SDR layers on one CRTC. Hardware without them (RDNA2, vkms, older i915) leaves them false and the scene falls back to the CRTC pipeline or to pre-composition.

Fields

has_degamma_lut: bool

PLANE_DEGAMMA_LUT is present.

has_ctm: bool

PLANE_CTM is present.

has_hdr_mult: bool

PLANE_HDR_MULT is present — a 16.16 fixed-point scalar applied to post-degamma linear values, used to lift SDR luminance into an HDR blend space.

degamma_lut_size: u32

How many drm_color_lut entries PLANE_DEGAMMA_LUT expects. Zero when the property is absent.
