--
-- == 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
-- 'Vulkan.Core10.Handles.Device'.
--
-- When using GLSL source-based shading languages, the
-- @clockRealtime*EXT@() timing functions map to the @OpReadClockKHR@
-- instruction with a scope of 'Vulkan.Core10.Handles.Device', and the
-- @clock*ARB@() timing functions map to the @OpReadClockKHR@ instruction
-- with a scope of @Subgroup@.
--
-- == New Structures
--
-- -   Extending
--     'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.PhysicalDeviceFeatures2',
--     'Vulkan.Core10.Device.DeviceCreateInfo':
--
--     -   'PhysicalDeviceShaderClockFeaturesKHR'
--
-- == New Enum Constants
--
-- -   'KHR_SHADER_CLOCK_EXTENSION_NAME'
--
-- -   'KHR_SHADER_CLOCK_SPEC_VERSION'
--
-- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_CLOCK_FEATURES_KHR'
