## Name

VkGraphicsShaderGroupCreateInfoNV - Structure specifying override parameters for each shader group

Loading… please wait.

## C Specification

The `VkGraphicsShaderGroupCreateInfoNV` structure provides the state overrides for each shader group. Each shader group behaves like a pipeline that was created from its state as well as the remaining parent’s state. It is defined as:

    // Provided by VK_NV_device_generated_commands
    typedef struct VkGraphicsShaderGroupCreateInfoNV {
        VkStructureType                                 sType;
        const void*                                     pNext;
        uint32_t                                        stageCount;
        const VkPipelineShaderStageCreateInfo*          pStages;
        const VkPipelineVertexInputStateCreateInfo*     pVertexInputState;
        const VkPipelineTessellationStateCreateInfo*    pTessellationState;
    } VkGraphicsShaderGroupCreateInfoNV;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `stageCount` is the number of entries in the `pStages` array.

- `pStages` is a pointer to an array VkPipelineShaderStageCreateInfo structures specifying the set of the shader stages to be included in this shader group.

- `pVertexInputState` is a pointer to a VkPipelineVertexInputStateCreateInfo structure.

- `pTessellationState` is a pointer to a VkPipelineTessellationStateCreateInfo structure, and is ignored if the shader group does not include a tessellation control shader stage and tessellation evaluation shader stage.

## Description

Valid Usage

- VUID-VkGraphicsShaderGroupCreateInfoNV-stageCount-02888
  For `stageCount`, the same restrictions as in VkGraphicsPipelineCreateInfo::`stageCount` apply

- VUID-VkGraphicsShaderGroupCreateInfoNV-pStages-02889
  For `pStages`, the same restrictions as in VkGraphicsPipelineCreateInfo::`pStages` apply

- VUID-VkGraphicsShaderGroupCreateInfoNV-pVertexInputState-02890
  For `pVertexInputState`, the same restrictions as in VkGraphicsPipelineCreateInfo::`pVertexInputState` apply

- VUID-VkGraphicsShaderGroupCreateInfoNV-pTessellationState-02891
  For `pTessellationState`, the same restrictions as in VkGraphicsPipelineCreateInfo::`pTessellationState` apply

Valid Usage (Implicit)

- VUID-VkGraphicsShaderGroupCreateInfoNV-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_GRAPHICS_SHADER_GROUP_CREATE_INFO_NV`

- VUID-VkGraphicsShaderGroupCreateInfoNV-pNext-pNext
  `pNext` must be `NULL`

- VUID-VkGraphicsShaderGroupCreateInfoNV-pStages-parameter
  `pStages` must be a valid pointer to an array of `stageCount` valid VkPipelineShaderStageCreateInfo structures

- VUID-VkGraphicsShaderGroupCreateInfoNV-stageCount-arraylength
  `stageCount` must be greater than `0`
