vkGetPhysicalDeviceQueueFamilyDataGraphPropertiesARM

To query the data graph processing engines and operations they support for a specific queue family of a physical device, call:

VkResult vkGetPhysicalDeviceQueueFamilyDataGraphPropertiesARM(
    VkPhysicalDevice                     physicalDevice,
    uint32_t                             queueFamilyIndex,
    uint32_t*                            pQueueFamilyDataGraphPropertyCount,
    VkQueueFamilyDataGraphPropertiesARM* pQueueFamilyDataGraphProperties);

pub fn get_physical_device_queue_family_data_graph_properties_arm(
    physical_device: vk::PhysicalDevice,
    queue_family_index: u32,
    p_queue_family_data_graph_property_count: *mut u32,
    p_queue_family_data_graph_properties: *mut vk::QueueFamilyDataGraphPropertiesARM,
) -> vk::Result;

• physicalDevice is the physical device to query.
• queueFamilyIndex is the index of the queue family being queried.
• pQueueFamilyDataGraphPropertyCount is a pointer to an integer related to the number of properties available or queried.
• pQueueFamilyDataGraphProperties is either NULL or a pointer to an array of VkQueueFamilyDataGraphPropertiesARM structures.

If pQueueFamilyDataGraphProperties is NULL, then the number of properties available is returned in pQueueFamilyDataGraphPropertyCount. Otherwise, pQueueFamilyDataGraphPropertyCount must point to a variable set by the application to the number of elements in the pQueueFamilyDataGraphProperties array, and on return the variable is overwritten with the number of structures actually written to pQueueFamilyDataGraphProperties. If pQueueFamilyDataGraphPropertyCount is less than the number of properties available, at most pQueueFamilyDataGraphPropertyCount structures will be written, and VK_INCOMPLETE will be returned instead of VK_SUCCESS, to indicate that not all the available properties were returned.

If the dataGraphModel feature is supported, the implementation must return at least one property with engine type VK_PHYSICAL_DEVICE_DATA_GRAPH_PROCESSING_ENGINE_TYPE_NEURAL_QCOM or VK_PHYSICAL_DEVICE_DATA_GRAPH_PROCESSING_ENGINE_TYPE_COMPUTE_QCOM.
