VkPhysicalDeviceShaderClockFeaturesKHR

The VkPhysicalDeviceShaderClockFeaturesKHR structure is defined as:

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

This structure describes the following features:

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• shaderSubgroupClock indicates whether shaders can perform Subgroup scoped clock reads.
• shaderDeviceClock indicates whether shaders can perform Device scoped clock reads.

If the VkPhysicalDeviceShaderClockFeaturesKHR 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. If the application wishes to use a VkDevice with any features described by VkPhysicalDeviceShaderClockFeaturesKHR, it must add an instance of the structure, with the desired feature members set to VK_TRUE, to the pNext chain of VkDeviceCreateInfo when creating the VkDevice.
