--
-- == Description
--
-- This extension provides the ability to determine device-specific
-- properties on NVIDIA GPUs. It provides the number of streaming
-- multiprocessors (SMs), the maximum number of warps (subgroups) that can
-- run on an SM, and shader builtins to enable invocations to identify
-- which SM and warp a shader invocation is executing on.
--
-- This extension enables support for the SPIR-V @ShaderSMBuiltinsNV@
-- capability.
--
-- These properties and built-ins /should/ typically only be used for
-- debugging purposes.
--
-- == New Structures
--
-- -   Extending
--     'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.PhysicalDeviceFeatures2',
--     'Vulkan.Core10.Device.DeviceCreateInfo':
--
--     -   'PhysicalDeviceShaderSMBuiltinsFeaturesNV'
--
-- -   Extending
--     'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.PhysicalDeviceProperties2':
--
--     -   'PhysicalDeviceShaderSMBuiltinsPropertiesNV'
--
-- == New Enum Constants
--
-- -   'NV_SHADER_SM_BUILTINS_EXTENSION_NAME'
--
-- -   'NV_SHADER_SM_BUILTINS_SPEC_VERSION'
--
-- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_SM_BUILTINS_FEATURES_NV'
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_SM_BUILTINS_PROPERTIES_NV'

--
-- == Issues
--
-- 1.  What should we call this extension?
--
--     __RESOLVED__: @NV_shader_sm_builtins@. Other options considered
--     included:
--
--     -   @NV_shader_smid@ - but SMID is really easy to typo\/confuse as
--         SIMD.
--
--     -   @NV_shader_sm_info@ - but __Info__ is typically reserved for
--         input structures
