# VkPhysicalDeviceShaderSMBuiltinsPropertiesNV(3) Manual Page

## Name

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

## C Specification

The `VkPhysicalDeviceShaderSMBuiltinsPropertiesNV` structure is defined as:

    typedef struct VkPhysicalDeviceShaderSMBuiltinsPropertiesNV {
        VkStructureType    sType;
        void*              pNext;
        uint32_t           shaderSMCount;
        uint32_t           shaderWarpsPerSM;
    } VkPhysicalDeviceShaderSMBuiltinsPropertiesNV;

## Members

The members of the `VkPhysicalDeviceShaderSMBuiltinsPropertiesNV` structure describe the following implementation-dependent limits:

## Description

- `sType` is the type of this structure.

- `pNext` is `NULL` or a pointer to an extension-specific structure.

- `shaderSMCount` is the number of SMs on the device.

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

If the `VkPhysicalDeviceShaderSMBuiltinsPropertiesNV` structure is included in the `pNext` chain of VkPhysicalDeviceProperties2, it is filled with the implementation-dependent limits.

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_SM_BUILTINS_PROPERTIES_NV`
