C Specification

To create a CUDA module, call:

// Provided by VK_NV_cuda_kernel_launch
VkResult vkCreateCudaModuleNV(
    VkDevice                                    device,
    const VkCudaModuleCreateInfoNV*             pCreateInfo,
    const VkAllocationCallbacks*                pAllocator,
    VkCudaModuleNV*                             pModule);

Parameters

  • device is the logical device that creates the shader module.

  • pCreateInfo is a pointer to a VkCudaModuleCreateInfoNV structure.

  • pAllocator controls host memory allocation as described in the Memory Allocation chapter.

  • pModule is a pointer to a VkCudaModuleNV handle in which the resulting CUDA module object is returned.

Description

Once a CUDA module has been created, the application may create the function entry point, which must refer to one function in the module.

Valid Usage (Implicit)

  • VUID-vkCreateCudaModuleNV-device-parameter
    device must be a valid VkDevice handle

  • VUID-vkCreateCudaModuleNV-pCreateInfo-parameter
    pCreateInfo must be a valid pointer to a valid VkCudaModuleCreateInfoNV structure

  • VUID-vkCreateCudaModuleNV-pAllocator-parameter
    If pAllocator is not NULL, pAllocator must be a valid pointer to a valid VkAllocationCallbacks structure

  • VUID-vkCreateCudaModuleNV-pModule-parameter
    pModule must be a valid pointer to a VkCudaModuleNV handle

Return Codes
On success, this command returns

  • VK_SUCCESS

On failure, this command returns

  • VK_ERROR_INITIALIZATION_FAILED

  • VK_ERROR_OUT_OF_HOST_MEMORY
