Interactions and External Dependencies

• This extension requires SPV_NV_shader_sm_builtins.
• This extension provides API support for GL_NV_shader_sm_builtins

Contributors

• Jeff Bolz, NVIDIA
• Eric Werness, NVIDIA

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 PhysicalDeviceFeatures2, DeviceCreateInfo:

  • PhysicalDeviceShaderSMBuiltinsFeaturesNV

• Extending PhysicalDeviceProperties2:

  • PhysicalDeviceShaderSMBuiltinsPropertiesNV

New Enum Constants

• NV_SHADER_SM_BUILTINS_EXTENSION_NAME

• NV_SHADER_SM_BUILTINS_SPEC_VERSION

• Extending StructureType:

  • STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_SM_BUILTINS_FEATURES_NV
  • STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_SM_BUILTINS_PROPERTIES_NV

New or Modified Built-In Variables

• WarpsPerSMNV

• SMCountNV
• WarpIDNV
• SMIDNV

New SPIR-V Capabilities

• ShaderSMBuiltinsNV

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

Version History

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.

Valid Usage (Implicit)

Constructors

PhysicalDeviceShaderSMBuiltinsPropertiesNV

Fields

• shaderSMCount :: Word32

  shaderSMCount is the number of SMs on the device.

• shaderWarpsPerSM :: Word32

  shaderWarpsPerSM is the maximum number of simultaneously executing warps on an SM.

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. PhysicalDeviceShaderSMBuiltinsFeaturesNV can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.
