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 & IOCTLs +=========================== + +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. + +Just like other DRM objects the drm_colorop objects are discovered via +IOCTLs: + +DRM_IOCTL_MODE_GETCOLOROPRESOURCES: This IOCTL is used to retrieve the +number of all drm_colorop objects. + +DRM_IOCTL_MODE_GETCOLOROP: This IOCTL is used to read one drm_colorop. +It includes the ID for the colorop object, as well as the plane_id of +the associated plane. All other values should be registered as +properties. + +Each drm_colorop has three core properties: + +TYPE: 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. While setting other properties might fail atomic check, +setting the BYPASS property to true should never fail. 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} + ├─ "LUT_1D_SIZE": immutable range = 4096 + ├─ "LUT_1D": 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} + ├─ "LUT_3D_SIZE": immutable range = 17 + ├─ "LUT_3D": blob + └─ "NEXT": immutable color operation ID = 73 + + +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 '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. + +The COLOR_PIPELINE property is only exposed when the +DRM_CLIENT_CAP_PLANE_COLOR_PIPELINE is set. Drivers are expected to +reject setting any existing pre-blend color operations when this cap is +set, such as COLOR_RANGE or 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. + +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 +3. iterate all COLOR_PIPELINE enum values +4. 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 + +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 + ├─ "MATRIX_3_4": 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 + ├─ "LUT_1D_SIZE": immutable range = 4096 + ├─ "LUT_1D_DATA": blob + └─ "NEXT" (immutable) = 48 + + Color operation 48 + ├─ "TYPE" (immutable) = 3D LUT + ├─ "LUT_3D_SIZE" (immutable) = 17 + ├─ "LUT_3D_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.

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 +disabled 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/drivers/gpu/drm/Makefile b/drivers/gpu/drm/Makefile index 104b42df2e95..4b14dcbb6117 100644 --- a/drivers/gpu/drm/Makefile +++ b/drivers/gpu/drm/Makefile @@ -16,6 +16,7 @@ drm-y := \ drm_client.o \ drm_client_modeset.o \ drm_color_mgmt.o \ + drm_colorop.o \ drm_connector.o \ drm_crtc.o \ drm_displayid.o \ diff --git a/drivers/gpu/drm/drm_atomic.c b/drivers/gpu/drm/drm_atomic.c index a91737adf8e7..ad8483972f56 100644 --- a/drivers/gpu/drm/drm_atomic.c +++ b/drivers/gpu/drm/drm_atomic.c @@ -42,6 +42,7 @@ #include <drm/drm_mode.h> #include <drm/drm_print.h> #include <drm/drm_writeback.h> +#include <drm/drm_colorop.h> #include "drm_crtc_internal.h" #include "drm_internal.h" @@ -108,6 +109,7 @@ void drm_atomic_state_default_release(struct drm_atomic_state *state) kfree(state->connectors); kfree(state->crtcs); kfree(state->planes); + kfree(state->colorops); kfree(state->private_objs); } EXPORT_SYMBOL(drm_atomic_state_default_release); @@ -139,6 +141,10 @@ drm_atomic_state_init(struct drm_device *dev, struct drm_atomic_state *state) sizeof(*state->planes), GFP_KERNEL); if (!state->planes) goto fail; + state->colorops = kcalloc(dev->mode_config.num_colorop, + sizeof(*state->colorops), GFP_KERNEL); + if (!state->colorops) + goto fail; /* * Because drm_atomic_state can be committed asynchronously we need our @@ -250,6 +256,20 @@ void drm_atomic_state_default_clear(struct drm_atomic_state *state) state->planes[i].new_state = NULL; } + for (i = 0; i < config->num_colorop; i++) { + struct drm_colorop *colorop = state->colorops[i].ptr; + + if (!colorop) + continue; + + drm_colorop_atomic_destroy_state(colorop, + state->colorops[i].state); + state->colorops[i].ptr = NULL; + state->colorops[i].state = NULL; + state->colorops[i].old_state = NULL; + state->colorops[i].new_state = NULL; + } + for (i = 0; i < state->num_private_objs; i++) { struct drm_private_obj *obj = state->private_objs[i].ptr; @@ -571,6 +591,56 @@ drm_atomic_get_plane_state(struct drm_atomic_state *state, } EXPORT_SYMBOL(drm_atomic_get_plane_state); + +/** + * drm_atomic_get_colorop_state - get colorop state + * @state: global atomic state object + * @colorop: colorop to get state object for + * + * This function returns the colorop state for the given colorop, allocating it + * if needed.
