VkPipelineCacheHeaderVersionDataGraphQCOM - Structure describing the layout of the pipeline cache header for data graphs

Description

The application should verify that the header info is compatible with the DataGraphProcessingEngineCreateInfoARM passed during pipeline creation. Implementations may return PIPELINE_COMPILE_REQUIRED_EXT from createDataGraphPipelinesARM if the cache is not compatible.

This cache type is built using offline compilation, therefore Vulkan does not define engine compatibility. The application should refer to the offline compiler used to create the cache for guidance on compatibility.

Unlike most structures declared by the Vulkan API, all fields of this structure are written with the least significant byte first, regardless of host byte-order.

The C language specification does not define the packing of structure members. This layout assumes tight structure member packing, with members laid out in the order listed in the structure, and the intended size of the structure is 28 bytes. If a compiler produces code that diverges from that pattern, applications must employ another method to set values at the correct offsets.

Valid Usage

• The dataGraphModel feature must be enabled

• headerSize must be 28

• headerVersion must be PIPELINE_CACHE_HEADER_VERSION_DATA_GRAPH_QCOM

• headerSize must not exceed the size of the pipeline cache

Valid Usage (Implicit)

• headerVersion must be a valid PipelineCacheHeaderVersion value

• cacheType must be a valid DataGraphModelCacheTypeQCOM value

VkDataGraphPipelineBuiltinModelCreateInfoQCOM - Structure specifying a built-in model for the newly created data graph pipeline

Description

The pipelineCache is ignored for the creation of this pipeline.

Applications can specify arguments to the built-in operation named in pOperation with DataGraphPipelineCompilerControlCreateInfoARM.

Applications should verify that the pVendorOptions, layout, and other state included with this pipeline creation are compatible with the pOperation. Implementations may fail if any state is not compatible and return PIPELINE_COMPILE_REQUIRED.

Built-in models are defined by the provider of the model, therefore Vulkan does not define model compatibility. The application should refer to the provider of the built-in model for guidance on compatibility.

Valid Usage

• All members of pOperation must be identical to a QueueFamilyDataGraphPropertiesARM::operation retrieved from getPhysicalDeviceQueueFamilyDataGraphPropertiesARM with the physicalDevice that was used to create device and paired in the retrieved results with a QueueFamilyDataGraphPropertiesARM::engine identical to an element of DataGraphProcessingEngineCreateInfoARM::pProcessingEngines provided in the pNext chain

Valid Usage (Implicit)

• sType must be STRUCTURE_TYPE_DATA_GRAPH_PIPELINE_BUILTIN_MODEL_CREATE_INFO_QCOM

• pOperation must be a valid pointer to a valid PhysicalDeviceDataGraphOperationSupportARM structure

VkPhysicalDeviceDataGraphModelFeaturesQCOM - Structure describing features to control data graph model

Description

If the PhysicalDeviceDataGraphModelFeaturesQCOM structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a Device with any features described by PhysicalDeviceDataGraphModelFeaturesQCOM, it must add an instance of the structure, with the desired feature members set to TRUE, to the pNext chain of DeviceCreateInfo when creating the Device.
