+ * 2. AMD driver private color management on &drm_plane and &drm_crtc
+ * 3. AMD plane color pipeline
+ *
+ * The CRTC properties are the original color management. When they were
+ * implemented per-plane color management was not a thing yet. Because
+ * of that we could get away with plumbing the DEGAMMA and CTM
+ * properties to pre-blending HW functions. This is incompatible with
+ * per-plane color management, such as via the AMD private properties or
+ * the new drm_plane color pipeline. The only compatible CRTC property
+ * with per-plane color management is the GAMMA property as it is
+ * applied post-blending.
+ *
+ * The AMD driver private color management properties are only exposed
+ * when the kernel is built explicitly with -DAMD_PRIVATE_COLOR. They
+ * are temporary building blocks on the path to full-fledged &drm_plane
+ * and &drm_crtc color pipelines and lay the driver's groundwork for the
+ * color pipelines.
+ *
+ * The AMD plane color pipeline describes AMD's &drm_colorops via the
+ * &drm_plane's COLOR_PIPELINE property.

+ * AMD Private Color Management on drm_plane
+ * -----------------------------------------
+ *
+ * The AMD private color management properties on a &drm_plane are:
*
- * The pipe blending also happens after these blocks so we don't actually
- * support any CRTC props with correct blending with multiple planes - but we
- * can still support CRTC color management properties in DM in most single
- * plane cases correctly with clever management of the DC interface in DM.
+ * - AMD_PLANE_DEGAMMA_LUT
+ * - AMD_PLANE_DEGAMMA_LUT_SIZE
+ * - AMD_PLANE_DEGAMMA_TF
+ * - AMD_PLANE_HDR_MULT

+ * - AMD_PLANE_LUT3D
+ * - AMD_PLANE_LUT3D_SIZE

- * As per DRM documentation, blocks should be in hardware bypass when their

+ *
+ * AMD plane color pipeline
+ * ------------------------
+ *
+ * The AMD &drm_plane color pipeline is advertised for DCN generations
+ * 3.0 and newer. It exposes these elements in this order:
+ *
+ * 1. 1D curve colorop
+ * 2. Multiplier
+ * 3. 3x4 CTM
+ * 4. 1D curve colorop
+ * 5. 1D LUT
+ * 6. 3D LUT
+ * 7. 1D curve colorop
+ * 8. 1D LUT
+ *
+ * The multiplier (#2) is a simple multiplier that is applied to all
+ * channels.
+ *
+ * The 3x4 CTM (#3) is a simple 3x4 matrix.
+ *
+ * #1, and #7 are non-linear to linear curves. #4 is a linear to
+ * non-linear curve. They support sRGB, PQ, and BT.709/BT.2020 EOTFs or
+ * their inverse.
+ *
+ * The 1D LUTs (#5 and #8) are plain 4096 entry LUTs.
+ *
+ * The 3DLUT (#6) is a tetrahedrally interpolated 17 cube LUT.
*
- * Plane DGM Bypass -> Plane CTM Bypass -> Plane RGM Bypass -> ...

+ * Extracts all software state variables that are used to program hardware register

+ *
+ * The function traverses the DC context and extracts values from:
+ * - Stream configurations (timing, format, DSC settings)
+ * - Plane states (surface format, rotation, scaling, cursor)
+ * - Pipe contexts (resource allocation, blending, viewport)
+ * - Clock manager (display clocks, DPP clocks, pixel clocks)
+ * - Resource context (DET buffer allocation, ODM configuration)
+ *
+ * This is essential for underflow debugging as it captures the exact software
+ * state that determines how registers are programmed, allowing analysis of
+ * whether underflow is caused by incorrect register programming or timing issues.
+ *
+ * Return: true if state was successfully captured, false on error

+/**
+ * DOC: overview
+ *
+ * When userspace signals the &DRM_CLIENT_CAP_PLANE_COLOR_PIPELINE it
+ * should use the COLOR_PIPELINE plane property and associated colorops
+ * for any color operation on the &drm_plane. Setting of all old color
+ * properties, such as COLOR_ENCODING and COLOR_RANGE, will be rejected
+ * and the values of the properties will be ignored.
+ *
+ * Colorops are only advertised and valid for atomic drivers and atomic
+ * userspace that signals the &DRM_CLIENT_CAP_PLANE_COLOR_PIPELINE
+ * client cap.
+ *
+ * A colorop represents a single color operation. Colorops are chained
+ * via the NEXT property and make up color pipelines. Color pipelines
+ * are advertised and selected via the COLOR_PIPELINE &drm_plane
+ * property.
+ *
+ * A colorop will be of a certain type, advertised by the read-only TYPE
+ * property. Each type of colorop will advertise a different set of
+ * properties and is programmed in a different manner. Types can be
+ * enumerated 1D curves, 1D LUTs, 3D LUTs, matrices, etc. See the
+ * &drm_colorop_type documentation for information on each type.
+ *
+ * If a colorop advertises the BYPASS property it can be bypassed.
+ *
+ * Information about colorop and color pipeline design decisions can be
+ * found at rfc/color_pipeline.rst, but note that this document will
+ * grow stale over time.
