# VkSubpassShadingPipelineCreateInfoHUAWEI(3) Manual Page

## Name

VkSubpassShadingPipelineCreateInfoHUAWEI - Structure specifying parameters of a newly created subpass shading pipeline

Loading… please wait.

## C Specification

A subpass shading pipeline is a compute pipeline which must be called only in a subpass of a render pass with work dimensions specified by render area size. The subpass shading pipeline shader is a compute shader allowed to access input attachments specified in the calling subpass. To create a subpass shading pipeline, call vkCreateComputePipelines with VkSubpassShadingPipelineCreateInfoHUAWEI in the `pNext` chain of VkComputePipelineCreateInfo.

The `VkSubpassShadingPipelineCreateInfoHUAWEI` structure is defined as:

    // Provided by VK_HUAWEI_subpass_shading
    typedef struct VkSubpassShadingPipelineCreateInfoHUAWEI {
        VkStructureType    sType;
        void*              pNext;
        VkRenderPass       renderPass;
        uint32_t           subpass;
    } VkSubpassShadingPipelineCreateInfoHUAWEI;

## Members

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

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

- `renderPass` is a handle to a render pass object describing the environment in which the pipeline will be used. The pipeline must only be used with a render pass instance compatible with the one provided. See Render Pass Compatibility for more information.

- `subpass` is the index of the subpass in the render pass where this pipeline will be used.

## Description

Valid Usage

- VUID-VkSubpassShadingPipelineCreateInfoHUAWEI-subpass-04946
  `subpass` must be created with `VK_PIPELINE_BIND_POINT_SUBPASS_SHADING_HUAWEI` bind point

Valid Usage (Implicit)

- VUID-VkSubpassShadingPipelineCreateInfoHUAWEI-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_SUBPASS_SHADING_PIPELINE_CREATE_INFO_HUAWEI`

- VUID-VkSubpassShadingPipelineCreateInfoHUAWEI-renderPass-parameter
  `renderPass` must be a valid VkRenderPass handle
