39“DEGAMMA_LUT”BLOB0CRTCDRM property to set the degamma lookup table (LUT) mapping pixel data from the framebuffer before it is given to the transformation matrix. The data is an interpreted as an array of struct drm_color_lut elements. Hardware might choose not to use the full precision of the LUT elements nor use all the elements of the LUT (for example the hardware might choose to interpolate between LUT[0] and LUT[4]).
40“DEGAMMA_LUT_SIZE”RANGE | IMMUTABLEMin=0, Max=UINT_MAXCRTCDRM property to gives the size of the lookup table to be set on the DEGAMMA_LUT property (the size depends on the underlying hardware).
41“CTM”BLOB0CRTCDRM property to set the current transformation matrix (CTM) apply to pixel data after the lookup through the degamma LUT and before the lookup through the gamma LUT. The data is an interpreted as a struct drm_color_ctm.
42“GAMMA_LUT”BLOB0CRTCDRM property to set the gamma lookup table (LUT) mapping pixel data after to the transformation matrix to data sent to the connector. The data is an interpreted as an array of struct drm_color_lut elements. Hardware might choose not to use the full precision of the LUT elements nor use all the elements of the LUT (for example the hardware might choose to interpolate between LUT[0] and LUT[4]).
43“GAMMA_LUT_SIZE”RANGE | IMMUTABLEMin=0, Max=UINT_MAXCRTCDRM property to gives the size of the lookup table to be set on the GAMMA_LUT property (the size depends on the underlying hardware).
44i915Generic"Broadcast RGB"ENUM{ "Automatic", "Full", "Limited 16:235" }ConnectorWhen this property is set to Limited 16:235 and CTM is set, the hardware will be programmed with the result of the multiplication of CTM by the limited range matrix to ensure the pixels normaly in the range 0..1.0 are remapped to the range 16/255..235/255.
