# VkPhysicalDeviceDataGraphModelFeaturesQCOM(3) Manual Page

## Name

VkPhysicalDeviceDataGraphModelFeaturesQCOM - Structure describing features to control data graph model

## C Specification

The `VkPhysicalDeviceDataGraphModelFeaturesQCOM` structure is defined as:

    // Provided by VK_QCOM_data_graph_model
    typedef struct VkPhysicalDeviceDataGraphModelFeaturesQCOM {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           dataGraphModel;
    } VkPhysicalDeviceDataGraphModelFeaturesQCOM;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `dataGraphModel` specifies whether the functionality defined by this extension is available, and guarantees that the implementation supports a data graph queue family with at least one of the following engine types:

  - VK_PHYSICAL_DEVICE_DATA_GRAPH_PROCESSING_ENGINE_TYPE_NEURAL_QCOM

  - VK_PHYSICAL_DEVICE_DATA_GRAPH_PROCESSING_ENGINE_TYPE_COMPUTE_QCOM

## Description

If the `VkPhysicalDeviceDataGraphModelFeaturesQCOM` structure is included in the `pNext` chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a VkDevice with any features described by `VkPhysicalDeviceDataGraphModelFeaturesQCOM`, it must add an instance of the structure, with the desired feature members set to VK_TRUE, to the `pNext` chain of VkDeviceCreateInfo when creating the VkDevice.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceDataGraphModelFeaturesQCOM-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_DATA_GRAPH_MODEL_FEATURES_QCOM

Structure Chaining

Extends the structures

  - VkDeviceCreateInfo

  - VkPhysicalDeviceFeatures2
