# VkPhysicalDeviceTimelineSemaphoreFeatures(3) Manual Page

## Name

VkPhysicalDeviceTimelineSemaphoreFeatures - Structure describing timeline semaphore features that can be supported by an implementation

## C Specification

The `VkPhysicalDeviceTimelineSemaphoreFeatures` structure is defined as:

    typedef struct VkPhysicalDeviceTimelineSemaphoreFeatures {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           timelineSemaphore;
    } VkPhysicalDeviceTimelineSemaphoreFeatures;

or the equivalent

    typedef VkPhysicalDeviceTimelineSemaphoreFeatures VkPhysicalDeviceTimelineSemaphoreFeaturesKHR;

## Members

The members of the `VkPhysicalDeviceTimelineSemaphoreFeatures` structure describe the following features:

## Description

- `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 VkPhysicalDeviceFeatures2, it is filled with values indicating whether each feature is supported. `VkPhysicalDeviceTimelineSemaphoreFeatures` can also be included in the `pNext` chain of VkDeviceCreateInfo to enable features.

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_TIMELINE_SEMAPHORE_FEATURES`
