SPDX-License-Identifier: GPL-2.0 + +======================== +Linux Color Pipeline API +======================== + +What problem are we solving? +============================ + +We would like to support pre-, and post-blending complex color +transformations in display controller hardware in order to allow for +HW-supported HDR use-cases, as well as to provide support to +color-managed applications, such as video or image editors. + +It is possible to support an HDR output on HW supporting the Colorspace +and HDR Metadata drm_connector properties, but that requires the +compositor or application to render and compose the content into one +final buffer intended for display. Doing so is costly. + +Most modern display HW offers various 1D LUTs, 3D LUTs, matrices, and other +operations to support color transformations. These operations are often +implemented in fixed-function HW and therefore much more power efficient than +performing similar operations via shaders or CPU. + +We would like to make use of this HW functionality to support complex color +transformations with no, or minimal CPU or shader load. + + +How are other OSes solving this problem? +======================================== + +The most widely supported use-cases regard HDR content, whether video or +gaming. + +Most OSes will specify the source content format (color gamut, encoding transfer +function, and other metadata, such as max and average light levels) to a driver. +Drivers will then program their fixed-function HW accordingly to map from a +source content buffer's space to a display's space. + +When fixed-function HW is not available the compositor will assemble a shader to +ask the GPU to perform the transformation from the source content format to the +display's format. + +A compositor's mapping function and a driver's mapping function are usually +entirely separate concepts. On OSes where a HW vendor has no insight into +closed-source compositor code such a vendor will tune their color management +code to visually match the compositor's. On other OSes, where both mapping +functions are open to an implementer they will ensure both mappings match. + +This results in mapping algorithm lock-in, meaning that no-one alone can +experiment with or introduce new mapping algorithms and achieve +consistent results regardless of which implementation path is taken. + +Why is Linux different? +======================= + +Unlike other OSes, where there is one compositor for one or more drivers, on +Linux we have a many-to-many relationship. Many compositors; many drivers. +In addition each compositor vendor or community has their own view of how +color management should be done. This is what makes Linux so beautiful. + +This means that a HW vendor can now no longer tune their driver to one +compositor, as tuning it to one could make it look fairly different from +another compositor's color mapping. + +We need a better solution. + + +Descriptive API +=============== + +An API that describes the source and destination colorspaces is a descriptive +API. It describes the input and output color spaces but does not describe +how precisely they should be mapped. Such a mapping includes many minute +design decision that can greatly affect the look of the final result. + +It is not feasible to describe such mapping with enough detail to ensure the +same result from each implementation. In fact, these mappings are a very active +research area. + + +Prescriptive API +================ + +A prescriptive API describes not the source and destination colorspaces. It +instead prescribes a recipe for how to manipulate pixel values to arrive at the +desired outcome. + +This recipe is generally an ordered list of straight-forward operations, +with clear mathematical definitions, such as 1D LUTs, 3D LUTs, matrices, +or other operations that can be described in a precise manner. + + +The Color Pipeline API +====================== + +HW color management pipelines can significantly differ between HW +vendors in terms of availability, ordering, and capabilities of HW +blocks. This makes a common definition of color management blocks and +their ordering nigh impossible. Instead we are defining an API that +allows user space to discover the HW capabilities in a generic manner, +agnostic of specific drivers and hardware. + + +drm_colorop Object +================== + +To support the definition of color pipelines we define the DRM core +object type drm_colorop. Individual drm_colorop objects will be chained +via the NEXT property of a drm_colorop to constitute a color pipeline. +Each drm_colorop object is unique, i.e., even if multiple color +pipelines have the same operation they won't share the same drm_colorop +object to describe that operation. + +Note that drivers are not expected to map drm_colorop objects statically +to specific HW blocks. The mapping of drm_colorop objects is entirely a +driver-internal detail and can be as dynamic or static as a driver needs +it to be. See more in the Driver Implementation Guide section below. + +Each drm_colorop has three core properties: + +TYPE: An enumeration property, definint the type of transformation, such as +* enumerated curve +* custom (uniform) 1D LUT +* 3x3 matrix +* 3x4 matrix +* 3D LUT +* etc. + +Depending on the type of transformation other properties will describe +more details. + +BYPASS: A boolean property that can be used to easily put a block into +bypass mode. The BYPASS property is not mandatory for a colorop, as long +as the entire pipeline can get bypassed by setting the COLOR_PIPELINE on +a plane to '0'. + +NEXT: The ID of the next drm_colorop in a color pipeline, or 0 if this +drm_colorop is the last in the chain. + +An example of a drm_colorop object might look like one of these:: + + /* 1D enumerated curve */ + Color operation 42 + ├─ "TYPE": immutable enum {1D enumerated curve, 1D LUT, 3x3 matrix, 3x4 matrix, 3D LUT, etc.} = 1D enumerated curve + ├─ "BYPASS": bool {true, false} + ├─ "CURVE_1D_TYPE": enum {sRGB EOTF, sRGB inverse EOTF, PQ EOTF, PQ inverse EOTF, …} + └─ "NEXT": immutable color operation ID = 43 + + /* custom 4k entry 1D LUT */ + Color operation 52 + ├─ "TYPE": immutable enum {1D enumerated curve, 1D LUT, 3x3 matrix, 3x4 matrix, 3D LUT, etc.} = 1D LUT + ├─ "BYPASS": bool {true, false} + ├─ "SIZE": immutable range = 4096 + ├─ "DATA": blob + └─ "NEXT": immutable color operation ID = 0 + + /* 17^3 3D LUT */ + Color operation 72 + ├─ "TYPE": immutable enum {1D enumerated curve, 1D LUT, 3x3 matrix, 3x4 matrix, 3D LUT, etc.} = 3D LUT + ├─ "BYPASS": bool {true, false} + ├─ "3DLUT_MODES": read-only blob of supported 3DLUT modes + ├─ "3DLUT_MODE_INDEX": index of selected 3DLUT mode + ├─ "DATA": blob + └─ "NEXT": immutable color operation ID = 73 + +drm_colorop extensibility +------------------------- + +Unlike existing DRM core objects, like &drm_plane, drm_colorop is not +extensible. This simplifies implementations and keeps all functionality +for managing &drm_colorop objects in the DRM core. + +If there is a need one may introduce a simple &drm_colorop_funcs +function table in the future, for example to support an IN_FORMATS +property on a &drm_colorop. + +If a driver requires the ability to create a driver-specific colorop +object they will need to add &drm_colorop func table support with +support for the usual functions, like destroy, atomic_duplicate_state, +and atomic_destroy_state. + + +COLOR_PIPELINE Plane Property +============================= + +Color Pipelines are created by a driver and advertised via a new +COLOR_PIPELINE enum property on each plane. Values of the property +always include object id 0, which is the default and means all color +processing is disabled. Additional values will be the object IDs of the +first drm_colorop in a pipeline. A driver can create and advertise none, +one, or more possible color pipelines. A DRM client will select a color +pipeline by setting the COLOR PIPELINE to the respective value. + +NOTE: Many DRM clients will set enumeration properties via the string +value, often hard-coding it. Since this enumeration is generated based +on the colorop object IDs it is important to perform the Color Pipeline +Discovery, described below, instead of hard-coding color pipeline +assignment. Drivers might generate the enum strings dynamically. +Hard-coded strings might only work for specific drivers on a specific +pieces of HW. Color Pipeline Discovery can work universally, as long as +drivers implement the required color operations. + +The COLOR_PIPELINE property is only exposed when the +DRM_CLIENT_CAP_PLANE_COLOR_PIPELINE is set. Drivers shall ignore any +existing pre-blend color operations when this cap is set, such as +COLOR_RANGE and COLOR_ENCODING. If drivers want to support COLOR_RANGE +or COLOR_ENCODING functionality when the color pipeline client cap is +set, they are expected to expose colorops in the pipeline to allow for +the appropriate color transformation. + +Setting of the COLOR_PIPELINE plane property or drm_colorop properties +is only allowed for userspace that sets this client cap. + +An example of a COLOR_PIPELINE property on a plane might look like this:: + + Plane 10 + ├─ "TYPE": immutable enum {Overlay, Primary, Cursor} = Primary + ├─ … + └─ "COLOR_PIPELINE": enum {0, 42, 52} = 0 + + +Color Pipeline Discovery +======================== + +A DRM client wanting color management on a drm_plane will: + +1. Get the COLOR_PIPELINE property of the plane +2. iterate all COLOR_PIPELINE enum values +3. for each enum value walk the color pipeline (via the NEXT pointers) + and see if the available color operations are suitable for the + desired color management operations + +If userspace encounters an unknown or unsuitable color operation during +discovery it does not need to reject the entire color pipeline outright, +as long as the unknown or unsuitable colorop has a "BYPASS" property. +Drivers will ensure that a bypassed block does not have any effect. + +An example of chained properties to define an AMD pre-blending color +pipeline might look like this:: + + Plane 10 + ├─ "TYPE" (immutable) = Primary + └─ "COLOR_PIPELINE": enum {0, 44} = 0 + + Color operation 44 + ├─ "TYPE" (immutable) = 1D enumerated curve + ├─ "BYPASS": bool + ├─ "CURVE_1D_TYPE": enum {sRGB EOTF, PQ EOTF} = sRGB EOTF + └─ "NEXT" (immutable) = 45 + + Color operation 45 + ├─ "TYPE" (immutable) = 3x4 Matrix + ├─ "BYPASS": bool + ├─ "DATA": blob + └─ "NEXT" (immutable) = 46 + + Color operation 46 + ├─ "TYPE" (immutable) = 1D enumerated curve + ├─ "BYPASS": bool + ├─ "CURVE_1D_TYPE": enum {sRGB Inverse EOTF, PQ Inverse EOTF} = sRGB EOTF + └─ "NEXT" (immutable) = 47 + + Color operation 47 + ├─ "TYPE" (immutable) = 1D LUT + ├─ "SIZE": immutable range = 4096 + ├─ "DATA": blob + └─ "NEXT" (immutable) = 48 + + Color operation 48 + ├─ "TYPE" (immutable) = 3D LUT + ├─ "3DLUT_MODE_INDEX": 0 + ├─ "DATA": blob + └─ "NEXT" (immutable) = 49 + + Color operation 49 + ├─ "TYPE" (immutable) = 1D enumerated curve + ├─ "BYPASS": bool + ├─ "CURVE_1D_TYPE": enum {sRGB EOTF, PQ EOTF} = sRGB EOTF + └─ "NEXT" (immutable) = 0 + + +Color Pipeline Programming +========================== + +Once a DRM client has found a suitable pipeline it will: + +1. Set the COLOR_PIPELINE enum value to the one pointing at the first + drm_colorop object of the desired pipeline +2. Set the properties for all drm_colorop objects in the pipeline to the + desired values, setting BYPASS to true for unused drm_colorop blocks, + and false for enabled drm_colorop blocks +3.

As noted above the +colorops can map to HW directly but don't need to do so. Here are some +suggestions on how to think about creating your color pipelines: + +- Try to expose pipelines that use already defined colorops, even if + your hardware pipeline is split differently. This allows existing + userspace to immediately take advantage of the hardware. + +- Additionally, try to expose your actual hardware blocks as colorops. + Define new colorop types where you believe it can offer significant + benefits if userspace learns to program them. + +- Avoid defining new colorops for compound operations with very narrow + scope. If you have a hardware block for a special operation that + cannot be split further, you can expose that as a new colorop type. + However, try to not define colorops for "use cases", especially if + they require you to combine multiple hardware blocks. + +- Design new colorops as prescriptive, not descriptive; by the + mathematical formula, not by the assumed input and output. + +A defined colorop type must be deterministic. The exact behavior of the +colorop must be documented entirely, whether via a mathematical formula +or some other description. Its operation can depend only on its +properties and input and nothing else, allowed error tolerance +notwithstanding. + + +Driver Forward/Backward Compatibility +===================================== + +As this is uAPI drivers can't regress color pipelines that have been +introduced for a given HW generation. New HW generations are free to +abandon color pipelines advertised for previous generations. +Nevertheless, it can be beneficial to carry support for existing color +pipelines forward as those will likely already have support in DRM +clients. + +Introducing new colorops to a pipeline is fine, as long as they can be +bypassed or are purely informational. DRM clients implementing support +for the pipeline can always skip unknown properties as long as they can +be confident that doing so will not cause unexpected results. + +If a new colorop doesn't fall into one of the above categories +(bypassable or informational) the modified pipeline would be unusable +for user space. In this case a new pipeline should be defined. + + +References +========== + +1. https://lore.kernel.org/dri-devel/QMers3awXvNCQlyhWdTtsPwkp5ie9bze_hD5nAccFW7a_RXlWjYB7MoUW_8CKLT2bSQwIXVi5H6VULYIxCdgvryZoAoJnC5lZgyK1QWn488=@emersion.fr/ \ No newline at end of file diff --git a/Documentation/gpu/rfc/index.rst b/Documentation/gpu/rfc/index.rst index 476719771eef..d3726adeca6a 100644 --- a/Documentation/gpu/rfc/index.rst +++ b/Documentation/gpu/rfc/index.rst @@ -31,3 +31,6 @@ host such documentation: .. toctree:: i915_vm_bind.rst + +.. toctree:: + color_pipeline.rst \ No newline at end of file diff --git a/drivers/gpu/drm/Makefile b/drivers/gpu/drm/Makefile index 4cd054188faf..d7741a85a542 100644 --- a/drivers/gpu/drm/Makefile +++ b/drivers/gpu/drm/Makefile @@ -41,6 +41,7 @@ drm-y := \ drm_bridge.o \ drm_cache.o \ drm_color_mgmt.o \ + drm_colorop.o \ drm_connector.o \ drm_crtc.o \ drm_displayid.o \ diff --git a/drivers/gpu/drm/amd/display/amdgpu_dm/Makefile b/drivers/gpu/drm/amd/display/amdgpu_dm/Makefile index ab2a97e354da..46158d67ab12 100644 --- a/drivers/gpu/drm/amd/display/amdgpu_dm/Makefile +++ b/drivers/gpu/drm/amd/display/amdgpu_dm/Makefile @@ -38,7 +38,8 @@ AMDGPUDM = \ amdgpu_dm_pp_smu.o \ amdgpu_dm_psr.o \ amdgpu_dm_replay.o \ - amdgpu_dm_wb.o + amdgpu_dm_wb.o \ + amdgpu_dm_colorop.o ifdef CONFIG_DRM_AMD_DC_FP AMDGPUDM += dc_fpu.o diff --git a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c index d9d7a07953e4..e700a74d565d 100644 --- a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c +++ b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c @@ -5656,6 +5656,10 @@ fill_plane_color_attributes(const struct drm_plane_state *plane_state, *color_space = COLOR_SPACE_SRGB; + /* Ignore properties when DRM_CLIENT_CAP_PLANE_COLOR_PIPELINE is set */ + if (plane_state->state && plane_state->state->plane_color_pipeline) + return 0; + /* DRM color properties only affect non-RGB formats. */ if (format < SURFACE_PIXEL_FORMAT_VIDEO_BEGIN) return 0; diff --git a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_color.c b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_color.c index ebabfe3a512f..56fb0870a2fc 100644 --- a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_color.c +++ b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_color.c @@ -25,6 +25,7 @@ #include "amdgpu.h" #include "amdgpu_mode.h" #include "amdgpu_dm.h" +#include "amdgpu_dm_colorop.h" #include "dc.h" #include "modules/color/color_gamma.h" #include "basics/conversion.h" @@ -32,6 +33,32 @@ /** * DOC: overview * + * We have three types of color management in the AMD display driver. + * 1. the legacy &drm_crtc DEGAMMA, CTM, and GAMMA properties + * 2.
