vkCmdBindPipelineShaderGroupNV(3)

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 VK_QUEUE_COMPUTE_BIT, or VK_QUEUE_GRAPHICS_BIT operations
VUID-vkCmdBindPipelineShaderGroupNV-videocoding
This command must only be called outside of a video coding scope
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
