C Specification

The XrGraphicsBindingVulkanKHR structure is defined as:

typedef struct XrGraphicsBindingVulkanKHR {
    XrStructureType             type;
    const void* XR_MAY_ALIAS    next;
    VkInstance                  instance;
    VkPhysicalDevice            physicalDevice;
    VkDevice                    device;
    uint32_t                    queueFamilyIndex;
    uint32_t                    queueIndex;
} XrGraphicsBindingVulkanKHR;

Members

Member Descriptions

  • type is the XrStructureType of this structure.

  • next is NULL or a pointer to an extension-specific structure.

  • instance is a valid Vulkan VkInstance.

  • physicalDevice is a valid Vulkan VkPhysicalDevice.

  • device is a valid Vulkan VkDevice.

  • queueFamilyIndex is a valid queue family index on device.

  • queueIndex is a valid queue index on device to be used for synchronization.

Description

When creating a Vulkan-backed XrSession, the application will provide a pointer to an XrGraphicsBindingVulkanKHR in the next chain of the XrSessionCreateInfo.

Valid Usage
Valid Usage (Implicit)

  • The [XR_KHR_vulkan_enable] extension must be enabled prior to using XrGraphicsBindingVulkanKHR

  • next must be NULL

  • instance must be a valid VkInstance value

  • physicalDevice must be a valid VkPhysicalDevice value

  • device must be a valid VkDevice value

  • queueFamilyIndex must be a valid uint32_t value

  • queueIndex must be a valid uint32_t value
