Merge tag 'drm-next-2025-12-03' of https://gitlab.freedesktop.org/drm/kernel
Pull drm updates from Dave Airlie: "There was a rather late merge of a new color pipeline feature, that some userspace projects are blocked on, and has seen a lot of work in amdgpu. This should have seen some time in -next. There is additional support for this for Intel, that if it arrives in the next day or two I'll pass it on in another pull request and you can decide if you want to take it. Highlights: - Arm Ethos NPU accelerator driver - new DRM color pipeline support - amdgpu will now run discrete SI/CIK cards instead of radeon, which enables vulkan support in userspace - msm gets gen8 gpu support -

+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. The switch between HW
+fixed-function blocks and shaders/CPU must be seamless with no visible
+difference when fallback to shaders/CPU is neceesary at any time.
+
+
+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, defining 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}
+ ├─ "SIZE": immutable range = 17
+ ├─ "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
+ ├─ "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. Perform (TEST_ONLY or not) atomic commit with all the other KMS
+ states it wishes to change
+
+To configure the pipeline for an HDR10 PQ plane and blending in linear
+space, a compositor might perform an atomic commit with the following
+property values::
+
+ Plane 10
+ └─ "COLOR_PIPELINE" = 42
+
+ Color operation 42
+ └─ "BYPASS" = true
+
+ Color operation 44
+ └─ "BYPASS" = true
+
+ Color operation 45
+ └─ "BYPASS" = true
+
+ Color operation 46
+ └─ "BYPASS" = true
+
+ Color operation 47
+ ├─ "DATA" = Gamut mapping + tone mapping + night mode
+ └─ "BYPASS" = false
+
+ Color operation 48
+ ├─ "CURVE_1D_TYPE" = PQ EOTF
+ └─ "BYPASS" = false
+
+
+Driver Implementer's Guide
+==========================
+
+What does this all mean for driver implementations? 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.

+Implement a new DUMB_CREATE2 ioctl
+----------------------------------
+
+The current DUMB_CREATE ioctl is not well defined. Instead of a pixel and
+framebuffer format, it only accepts a color mode of vague semantics. Assuming
+a linear framebuffer, the color mode gives an idea of the supported pixel
+format. But userspace effectively has to guess the correct values. It really
+only works reliably with framebuffers in XRGB8888. Userspace has begun to
+workaround these limitations by computing arbitrary format's buffer sizes and
+calculating their sizes in terms of XRGB8888 pixels.
+
+One possible solution is a new ioctl DUMB_CREATE2. It should accept a DRM
+format and a format modifier to resolve the color mode's ambiguity. As
+framebuffers can be multi-planar, the new ioctl has to return the buffer size,
+pitch and GEM handle for each individual color plane.
+
+In the first step, the new ioctl can be limited to the current features of
+the existing DUMB_CREATE. Individual drivers can then be extended to support
+multi-planar formats. Rockchip might require this and would be a good candidate.
+
+It might also be helpful to userspace to query information about the size of
+a potential buffer, if allocated. Userspace would supply geometry and format;
+the kernel would return minimal allocation sizes and scanline pitch. There is
+interest to allocate that memory from another device and provide it to the
+DRM driver (say via dma-buf).
+
+Another requested feature is the ability to allocate a buffer by size, without
+format. Accelators use this for their buffer allocation and it could likely be
+generalized.
+
+In addition to the kernel implementation, there must be user-space support
+for the new ioctl. There's code in Mesa that might be able to use the new
+call.

+Start by mounting configfs and loading VKMS::
+
+ sudo mount -t configfs none /config
+ sudo modprobe vkms
+
+Once VKMS is loaded, ``/config/vkms`` is created automatically. Each directory
+under ``/config/vkms`` represents a VKMS instance, create a new one::
+
+ sudo mkdir /config/vkms/my-vkms
+
+By default, the instance is disabled::
+
+ cat /config/vkms/my-vkms/enabled
+ 0
+
+And directories are created for each configurable item of the display pipeline::
+
+ tree /config/vkms/my-vkms
+ ├── connectors
+ ├── crtcs
+ ├── enabled
+ ├── encoders
+ └── planes
+
+To add items to the display pipeline, create one or more directories under the
+available paths.
+
+Start by creating one or more planes::
+
+ sudo mkdir /config/vkms/my-vkms/planes/plane0
+
+Planes have 1 configurable attribute:
+
+- type: Plane type: 0 overlay, 1 primary, 2 cursor (same values as those
+ exposed by the "type" property of a plane)
+
+Continue by creating one or more CRTCs::
+
+ sudo mkdir /config/vkms/my-vkms/crtcs/crtc0
+
+CRTCs have 1 configurable attribute:
+
+- writeback: Enable or disable writeback connector support by writing 1 or 0
+
+Next, create one or more encoders::
+
+ sudo mkdir /config/vkms/my-vkms/encoders/encoder0
+
+Last but not least, create one or more connectors::
+
+ sudo mkdir /config/vkms/my-vkms/connectors/connector0
+
+Connectors have 1 configurable attribute:
+
+- status: Connection status: 1 connected, 2 disconnected, 3 unknown (same values
+ as those exposed by the "status" property of a connector)

-- Configure planes/crtcs/connectors (we'd need some code to have more than 1 of
- them first).
-
- Change output configuration: Plug/unplug screens, change EDID, allow changing
the refresh rate.
-The currently proposed solution is to expose vkms configuration through
-configfs. All existing module options should be supported through configfs
-too.

+
+Naming Convention
+=================
+
+``dma-buf`` heaps name should meet a number of constraints:
+
+- The name must be stable, and must not change from one version to the other.
+ Userspace identifies heaps by their name, so if the names ever change, we
+ would be likely to introduce regressions.
+
+- The name must describe the memory region the heap will allocate from, and
+ must uniquely identify it in a given platform. Since userspace applications
+ use the heap name as the discriminant, it must be able to tell which heap it
+ wants to use reliably if there's multiple heaps.
+
+- The name must not mention implementation details, such as the allocator. The
+ heap driver will change over time, and implementation details when it was
+ introduced might not be relevant in the future.
+
+- The name should describe properties of the buffers that would be allocated.
+ Doing so will make heap identification easier for userspace. Such properties
+ are:
+
+ - ``contiguous`` for physically contiguous buffers;
+
+ - ``protected`` for encrypted buffers not accessible the OS;
+
+- The name may describe intended usage. Doing so will make heap identification
+ easier for userspace applications and users.
+
+For example, assuming a platform with a reserved memory region located
+at the RAM address 0x42000000, intended to allocate video framebuffers,
+physically contiguous, and backed by the CMA kernel allocator, good
+names would be ``memory@42000000-contiguous`` or ``video@42000000``, but
+``cma-video`` wouldn't.
