C Specification

The VkDeviceQueueCreateInfo structure is defined as:

// Provided by VK_VERSION_1_0
typedef struct VkDeviceQueueCreateInfo {
    VkStructureType             sType;
    const void*                 pNext;
    VkDeviceQueueCreateFlags    flags;
    uint32_t                    queueFamilyIndex;
    uint32_t                    queueCount;
    const float*                pQueuePriorities;
} VkDeviceQueueCreateInfo;

Members

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • flags is a bitmask indicating behavior of the queues.

  • queueFamilyIndex is an unsigned integer indicating the index of the queue family in which to create the queues on this device. This index corresponds to the index of an element of the pQueueFamilyProperties array that was returned by vkGetPhysicalDeviceQueueFamilyProperties.

  • queueCount is an unsigned integer specifying the number of queues to create in the queue family indicated by queueFamilyIndex, and with the behavior specified by flags.

  • pQueuePriorities is a pointer to an array of queueCount normalized floating-point values, specifying priorities of work that will be submitted to each created queue. See Queue Priority for more information.

Description

Some queue families support functionality which requires a device feature or extension to be enabled, as indicated by the VkQueueFamilyProperties::queueFlags member. Applications may create such queues and submit queue submission commands to them without enabling the corresponding feature or extension, but must not utilize the specific functionality that they did not enable.

For example, sparse memory management operations can be performed on queues from queue families exposing the VK_QUEUE_SPARSE_BINDING_BIT bit, provided the sparseBinding feature is enabled. If a queue family supports both the VK_QUEUE_SPARSE_BINDING_BIT and VK_QUEUE_TRANSFER_BIT bits, applications may create a queue from this family and issue transfer operations without enabling the sparseBinding feature.

Valid Usage
Valid Usage (Implicit)

  • VUID-VkDeviceQueueCreateInfo-sType-sType
    sType must be VK_STRUCTURE_TYPE_DEVICE_QUEUE_CREATE_INFO

  • VUID-VkDeviceQueueCreateInfo-pNext-pNext
    Each pNext member of any structure (including this one) in the pNext chain must be either NULL or a pointer to a valid instance of VkDeviceQueueGlobalPriorityCreateInfo or VkDeviceQueueShaderCoreControlCreateInfoARM

  • VUID-VkDeviceQueueCreateInfo-sType-unique
    The sType value of each structure in the pNext chain must be unique

  • VUID-VkDeviceQueueCreateInfo-flags-parameter
    flags must be a valid combination of VkDeviceQueueCreateFlagBits values

  • VUID-VkDeviceQueueCreateInfo-pQueuePriorities-parameter
    pQueuePriorities must be a valid pointer to an array of queueCount float values

  • VUID-VkDeviceQueueCreateInfo-queueCount-arraylength
    queueCount must be greater than 0
