C Specification

To query shader clock support, call vkGetPhysicalDeviceFeatures2 with a VkPhysicalDeviceShaderClockFeaturesKHR structure included in the pNext chain of its pFeatures parameter.

The VkPhysicalDeviceShaderClockFeaturesKHR structure is defined as:

typedef struct VkPhysicalDeviceShaderClockFeaturesKHR {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           shaderSubgroupClock;
    VkBool32           shaderDeviceClock;
} VkPhysicalDeviceShaderClockFeaturesKHR;

Members

  • sType is the type of this structure.

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

  • shaderSubgroupClock indicates whether shaders can support Subgroup scoped clock reads.

  • shaderDeviceClock indicates whether shaders can support Device scoped clock reads.

Description

If the VkPhysicalDeviceShaderClockFeaturesKHR structure is included in the pNext chain of VkPhysicalDeviceFeatures2, it is filled with values indicating whether each feature is supported. VkPhysicalDeviceShaderClockFeaturesKHR can also be used in pNext chain of VkDeviceCreateInfo to enable the features.

Valid Usage (Implicit)
  • sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_CLOCK_FEATURES_KHR
