C Specification

Commands can be preprocessed prior execution using the following command:

// Provided by VK_NV_device_generated_commands
void vkCmdPreprocessGeneratedCommandsNV(
    VkCommandBuffer                             commandBuffer,
    const VkGeneratedCommandsInfoNV*            pGeneratedCommandsInfo);


  • commandBuffer is the command buffer which does the preprocessing.

  • pGeneratedCommandsInfo is a pointer to an instance of the VkGeneratedCommandsInfoNV structure containing parameters affecting the preprocessing step.


Valid Usage
  • VUID-vkCmdPreprocessGeneratedCommandsNV-commandBuffer-02974
    commandBuffer must not be a protected command buffer

  • VUID-vkCmdPreprocessGeneratedCommandsNV-pGeneratedCommandsInfo-02927
    pGeneratedCommandsInfo`s indirectCommandsLayout must have been created with the VK_INDIRECT_COMMANDS_LAYOUT_USAGE_EXPLICIT_PREPROCESS_BIT_NV bit set

  • VUID-vkCmdPreprocessGeneratedCommandsNV-deviceGeneratedCommands-02928
    The VkPhysicalDeviceDeviceGeneratedCommandsFeaturesNV::deviceGeneratedCommands feature must be enabled

Valid Usage (Implicit)
  • VUID-vkCmdPreprocessGeneratedCommandsNV-commandBuffer-parameter
    commandBuffer must be a valid VkCommandBuffer handle

  • VUID-vkCmdPreprocessGeneratedCommandsNV-pGeneratedCommandsInfo-parameter
    pGeneratedCommandsInfo must be a valid pointer to a valid VkGeneratedCommandsInfoNV structure

  • VUID-vkCmdPreprocessGeneratedCommandsNV-commandBuffer-recording
    commandBuffer must be in the recording state

  • VUID-vkCmdPreprocessGeneratedCommandsNV-commandBuffer-cmdpool
    The VkCommandPool that commandBuffer was allocated from must support graphics, or compute operations

  • VUID-vkCmdPreprocessGeneratedCommandsNV-renderpass
    This command must only be called outside of a render pass instance

Host Synchronization
  • Host access to commandBuffer must be externally synchronized

  • Host access to the VkCommandPool that commandBuffer was allocated from must be externally synchronized
