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.

VkPhysicalDeviceShaderClockFeaturesKHR - Structure describing features supported by VK_KHR_shader_clock

Members

This structure describes the following features:

Description

If the PhysicalDeviceShaderClockFeaturesKHR structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. PhysicalDeviceShaderClockFeaturesKHR can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.
