VkGraphicsShaderGroupCreateInfoNV(3)

Name

VkGraphicsShaderGroupCreateInfoNV - Structure specifying override parameters for each shader group

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
