C Specification

The VkPhysicalDeviceTimelineSemaphoreFeatures structure is defined as:

// Provided by VK_VERSION_1_2
typedef struct VkPhysicalDeviceTimelineSemaphoreFeatures {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           timelineSemaphore;
} VkPhysicalDeviceTimelineSemaphoreFeatures;

or the equivalent

// Provided by VK_KHR_timeline_semaphore
typedef VkPhysicalDeviceTimelineSemaphoreFeatures VkPhysicalDeviceTimelineSemaphoreFeaturesKHR;


This structure describes the following feature:


  • sType is the type of this structure.

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

  • timelineSemaphore indicates whether semaphores created with a VkSemaphoreType of VK_SEMAPHORE_TYPE_TIMELINE are supported.

If the VkPhysicalDeviceTimelineSemaphoreFeatures 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. VkPhysicalDeviceTimelineSemaphoreFeatures can also be used in the pNext chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)
  • VUID-VkPhysicalDeviceTimelineSemaphoreFeatures-sType-sType
