++/* Pre-defined Transfer Functions (TF)
++ *
++ * AMD driver supports pre-defined mathematical functions for transferring
++ * between encoded values and optical/linear space. Depending on HW color caps,
++ * ROMs and curves built by the AMD color module support these transforms.
++ *
++ * The driver-specific color implementation exposes properties for pre-blending
++ * degamma TF, shaper TF (before 3D LUT), and blend(dpp.ogam) TF and
++ * post-blending regamma (mpc.ogam) TF. However, only pre-blending degamma
++ * supports ROM curves. AMD color module uses pre-defined coefficients to build
++ * curves for the other blocks. What can be done by each color block is
++ * described by struct dpp_color_capsand struct mpc_color_caps.
++ *
++ * AMD driver-specific color API exposes the following pre-defined transfer
++ * functions:
++ *
++ * - Linear/Unity: linear/identity relationship between pixel value and
++ *   luminance value;
++ * - Gamma 2.2, Gamma 2.4, Gamma 2.6: pure gamma functions;
++ * - sRGB: 2.4 gamma with small initial linear section as standardized by IEC
++ *   61966-2-1:1999;
++ * - BT.709 (BT.1886): 2.4 gamma with differences in the dark end of the scale.
++ *   Used in HD-TV and standardized by ITU-R BT.1886;
++ * - PQ (Perceptual Quantizer): used for HDR display, allows luminance range
++ *   capability of 0 to 10,000 nits; standardized by SMPTE ST 2084.
++ *
++ * In the driver-specific API, color block names attached to TF properties
++ * suggest the intention regarding non-linear encoding pixel's luminance
++ * values. As some newer encodings don't use gamma curve, we make encoding and
++ * decoding explicit by defining an enum list of transfer functions supported
++ * in terms of EOTF and inverse EOTF, where:
++ *
++ * - EOTF (electro-optical transfer function): is the transfer function to go
++ *   from the encoded value to an optical (linear) value. De-gamma functions
++ *   traditionally do this.
++ * - Inverse EOTF (simply the inverse of the EOTF): is usually intended to go
++ *   from an optical/linear space (which might have been used for blending)
++ *   back to the encoded values. Gamma functions traditionally do this.
