C Specification

The generation of commands on the device requires a preprocess buffer. To retrieve the memory size and alignment requirements of a particular execution state call:

// Provided by VK_NV_device_generated_commands
void vkGetGeneratedCommandsMemoryRequirementsNV(
    VkDevice                                    device,
    const VkGeneratedCommandsMemoryRequirementsInfoNV* pInfo,
    VkMemoryRequirements2*                      pMemoryRequirements);


  • device is the logical device that owns the buffer.

  • pInfo is a pointer to an instance of the VkGeneratedCommandsMemoryRequirementsInfoNV structure containing parameters required for the memory requirements query.

  • pMemoryRequirements points to an instance of the VkMemoryRequirements2 structure in which the memory requirements of the buffer object are returned.


Valid Usage
Valid Usage (Implicit)
  • VUID-vkGetGeneratedCommandsMemoryRequirementsNV-device-parameter
    device must be a valid VkDevice handle

  • VUID-vkGetGeneratedCommandsMemoryRequirementsNV-pInfo-parameter
    pInfo must be a valid pointer to a valid VkGeneratedCommandsMemoryRequirementsInfoNV structure

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