Description

This extension advertises the SPIR-V ShaderClockKHR capability for Vulkan, which allows a shader to query a real-time or monotonically incrementing counter at the subgroup level or across the device level. The two valid SPIR-V scopes for OpReadClockKHR are Subgroup and Device.

When using GLSL source-based shading languages, the clockRealtime*EXT() timing functions map to the OpReadClockKHR instruction with a scope of Device, and the clock*ARB() timing functions map to the OpReadClockKHR instruction with a scope of Subgroup.

Synopsis

Documentation

data PhysicalDeviceShaderClockFeaturesKHR Source #

VkPhysicalDeviceShaderClockFeaturesKHR - Structure describing features supported by VK_KHR_shader_clock

Description

If the PhysicalDeviceShaderClockFeaturesKHR structure is included in the pNext chain of PhysicalDeviceFeatures2, it is filled with values indicating whether each feature is supported. PhysicalDeviceShaderClockFeaturesKHR can also be included in the pNext chain of DeviceCreateInfo to enable the features.
