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. If the application wishes to use a
Device with any features described by
PhysicalDeviceShaderClockFeaturesKHR, it must add an instance of the
structure, with the desired feature members set to
TRUE, to the pNext chain of
DeviceCreateInfo when creating the
Device.
