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

New Enum Constants

New or Modified Built-In Variables

New SPIR-V Capabilities

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

VkPhysicalDeviceShaderSMBuiltinsPropertiesNV - Structure describing shader SM Builtins properties supported by an implementation

Description

If the PhysicalDeviceShaderSMBuiltinsPropertiesNV structure is included in the pNext chain of the PhysicalDeviceProperties2 structure passed to getPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

VkPhysicalDeviceShaderSMBuiltinsFeaturesNV - Structure describing the shader SM Builtins features that can be supported by an implementation

Members

This structure describes the following feature:

Description

If the PhysicalDeviceShaderSMBuiltinsFeaturesNV 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 PhysicalDeviceShaderSMBuiltinsFeaturesNV, 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.
