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:

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

Members

  • sType is the type of this structure.

  • pNext is NULL or a pointer to an extension-specific structure.

  • stageCount is the number of entries in the pStages array.

  • pStages is an array of size stageCount structures of type VkPipelineShaderStageCreateInfo describing the set of the shader stages to be included in this shader group.

  • pVertexInputState is a pointer to an instance of the VkPipelineVertexInputStateCreateInfo structure.

  • pTessellationState is a pointer to an instance of the 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
  • For stageCount, the same restrictions as in VkGraphicsPipelineCreateInfo::stageCount apply.

  • For pStages, the same restrictions as in VkGraphicsPipelineCreateInfo::pStages apply.

  • For pVertexInputState, the same restrictions as in VkGraphicsPipelineCreateInfo::pVertexInputState apply.

  • For pTessellationState, the same restrictions as in VkGraphicsPipelineCreateInfo::pTessellationState apply.

Valid Usage (Implicit)
  • sType must be VK_STRUCTURE_TYPE_GRAPHICS_SHADER_GROUP_CREATE_INFO_NV

  • pNext must be NULL

  • pStages must be a valid pointer to an array of stageCount valid VkPipelineShaderStageCreateInfo structures

  • stageCount must be greater than 0
