C Specification

To determine the memory requirements for a compute pipeline’s metadata, call:

// Provided by VK_NV_device_generated_commands_compute
void vkGetPipelineIndirectMemoryRequirementsNV(
    VkDevice                                    device,
    const VkComputePipelineCreateInfo*          pCreateInfo,
    VkMemoryRequirements2*                      pMemoryRequirements);

Parameters

  • device is the logical device that owns the buffer.

  • pCreateInfo is a VkComputePipelineCreateInfo structure specifying the creation parameters of the compute pipeline whose memory requirements are being queried.

  • pMemoryRequirements is a pointer to a VkMemoryRequirements2 structure in which the requested pipeline’s memory requirements are returned.

Description

If pCreateInfo->pNext chain includes a pointer to a VkComputePipelineIndirectBufferInfoNV structure, then the contents of that structure are ignored.

Valid Usage
Valid Usage (Implicit)

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

  • VUID-vkGetPipelineIndirectMemoryRequirementsNV-pCreateInfo-parameter
    pCreateInfo must be a valid pointer to a valid VkComputePipelineCreateInfo structure

  • VUID-vkGetPipelineIndirectMemoryRequirementsNV-pMemoryRequirements-parameter
    pMemoryRequirements must be a valid pointer to a VkMemoryRequirements2 structure
