## Name

VkPhysicalDeviceShaderClockFeaturesKHR - Structure describing features supported by VK_KHR_shader_clock

Loading… please wait.

## C Specification

The VkPhysicalDeviceShaderClockFeaturesKHR structure is defined as:

    // Provided by VK_KHR_shader_clock
    typedef struct VkPhysicalDeviceShaderClockFeaturesKHR {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           shaderSubgroupClock;
        VkBool32           shaderDeviceClock;
    } VkPhysicalDeviceShaderClockFeaturesKHR;

## Members

This structure describes the following features:

## Description

- `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. `VkPhysicalDeviceShaderClockFeaturesKHR` can also be used in the `pNext` chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceShaderClockFeaturesKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_CLOCK_FEATURES_KHR`
