vkGetPhysicalDeviceQueueFamilyDataGraphPropertiesARM(3)

Name

vkGetPhysicalDeviceQueueFamilyDataGraphPropertiesARM - Query the data processing engines and the operations they support for a given queue family of a physical device

C Specification

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

// Provided by VK_ARM_data_graph
VkResult vkGetPhysicalDeviceQueueFamilyDataGraphPropertiesARM(
    VkPhysicalDevice                            physicalDevice,
    uint32_t                                    queueFamilyIndex,
    uint32_t*                                   pQueueFamilyDataGraphPropertyCount,
    VkQueueFamilyDataGraphPropertiesARM*        pQueueFamilyDataGraphProperties);

Parameters

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.

Description

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.

Valid Usage (Implicit)

VUID-vkGetPhysicalDeviceQueueFamilyDataGraphPropertiesARM-physicalDevice-parameter
physicalDevice must be a valid VkPhysicalDevice handle
VUID-vkGetPhysicalDeviceQueueFamilyDataGraphPropertiesARM-pQueueFamilyDataGraphPropertyCount-parameter
pQueueFamilyDataGraphPropertyCount must be a valid pointer to a uint32_t value
VUID-vkGetPhysicalDeviceQueueFamilyDataGraphPropertiesARM-pQueueFamilyDataGraphProperties-parameter
If the value referenced by pQueueFamilyDataGraphPropertyCount is not 0, and pQueueFamilyDataGraphProperties is not NULL, pQueueFamilyDataGraphProperties must be a valid pointer to an array of pQueueFamilyDataGraphPropertyCount VkQueueFamilyDataGraphPropertiesARM structures

Return Codes

Success

Failure
