C Specification

For pipelines that were created with the support of multiple shader groups (see Graphics Pipeline Shader Groups), the regular vkCmdBindPipeline command will bind Shader Group 0. To explicitly bind a shader group use:

// Provided by VK_NV_device_generated_commands
void vkCmdBindPipelineShaderGroupNV(
    VkCommandBuffer                             commandBuffer,
    VkPipelineBindPoint                         pipelineBindPoint,
    VkPipeline                                  pipeline,
    uint32_t                                    groupIndex);

Parameters

  • commandBuffer is the command buffer that the pipeline will be bound to.

  • pipelineBindPoint is a VkPipelineBindPoint value specifying the bind point to which the pipeline will be bound.

  • pipeline is the pipeline to be bound.

  • groupIndex is the shader group to be bound.

Description

Valid Usage
  • VUID-vkCmdBindPipelineShaderGroupNV-groupIndex-02893
    groupIndex must be 0 or less than the effective VkGraphicsPipelineShaderGroupsCreateInfoNV::groupCount including the referenced pipelines

  • VUID-vkCmdBindPipelineShaderGroupNV-pipelineBindPoint-02894
    The pipelineBindPoint must be VK_PIPELINE_BIND_POINT_GRAPHICS

  • VUID-vkCmdBindPipelineShaderGroupNV-groupIndex-02895
    The same restrictions as vkCmdBindPipeline apply as if the bound pipeline was created only with the Shader Group from the groupIndex information

  • VUID-vkCmdBindPipelineShaderGroupNV-deviceGeneratedCommands-02896
    The VkPhysicalDeviceDeviceGeneratedCommandsFeaturesNV::deviceGeneratedCommands feature must be enabled

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

  • VUID-vkCmdBindPipelineShaderGroupNV-pipelineBindPoint-parameter
    pipelineBindPoint must be a valid VkPipelineBindPoint value

  • VUID-vkCmdBindPipelineShaderGroupNV-pipeline-parameter
    pipeline must be a valid VkPipeline handle

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

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

  • VUID-vkCmdBindPipelineShaderGroupNV-commonparent
    Both of commandBuffer, and pipeline must have been created, allocated, or retrieved from the same VkDevice

Host Synchronization
  • Host access to commandBuffer must be externally synchronized

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