c++ - vkCreateGraphicsPipelines 上的读取访问冲突

Question

我正在 vulkan 中(暂时)制作一个简单的渲染器，目前我正在让它变得非常简单。我在 vkCreateGraphicsPipelines() 中遇到异常，可能是什么问题，我该如何解决。

我试过寻找任何尚未初始化的东西，但到目前为止什么都没有。我已经检查了调用堆栈，但没有得到任何结果，因为在调用管道的创建函数时抛出了异常。我也在谷歌上搜索过，但没有找到任何帮助。我正在关注 vulkan-tutorial 网站，只是将它抽象到不同的类中，多次检查教程。一切正常，直到我进入 vkCreateGraphicsPipelines 函数。

VkPipelineShaderStageCreateInfo shaderStages[] = { p_Model->shader.vertShaderStageInfo, p_Model->shader.fragShaderStageInfo };

VkPipelineVertexInputStateCreateInfo vertexInputInfo = {};
vertexInputInfo.sType = VK_STRUCTURE_TYPE_PIPELINE_VERTEX_INPUT_STATE_CREATE_INFO;

vertexInputInfo.vertexBindingDescriptionCount       = 1;
vertexInputInfo.vertexAttributeDescriptionCount     = static_cast<uint32_t>(p_Model->mesh.vao.getAttributeDescriptions().size());
vertexInputInfo.pVertexBindingDescriptions          = &p_Model->mesh.vao.getBindingDescription();
vertexInputInfo.pVertexAttributeDescriptions        = p_Model->mesh.vao.getAttributeDescriptions().data();

//Set info for graphics pipeline creation
VkPipelineInputAssemblyStateCreateInfo  inputAssembly           = getInputAssemblyInfo();
VkViewport                              viewport                = getViewport();
VkRect2D                                scissor                 = getScissor();
VkPipelineViewportStateCreateInfo       viewportState           = getViewportStateInfo(viewport, scissor);
VkPipelineRasterizationStateCreateInfo  rasterizer              = getRasterizerInfo();
VkPipelineMultisampleStateCreateInfo    multiSampling           = getMultiSamplingInfo();
VkPipelineColorBlendAttachmentState     colorBlendAttachment    = getColorBlendAttachmentState();
VkPipelineColorBlendStateCreateInfo     colorBlending           = getColorBlendStateInfo(colorBlendAttachment);
VkPipelineDynamicStateCreateInfo        dynamicState            = getDynamicStateInfo();
VkPipelineLayoutCreateInfo              pipelineLayoutInfo      = getPipelineLayoutInfo();

//Filling pipeline info 
VkGraphicsPipelineCreateInfo pipelineInfo = {};
pipelineInfo.sType                  = VK_STRUCTURE_TYPE_GRAPHICS_PIPELINE_CREATE_INFO;
pipelineInfo.stageCount             = 2;
pipelineInfo.pStages                = shaderStages;
pipelineInfo.pVertexInputState      = &vertexInputInfo;
pipelineInfo.pInputAssemblyState    = &inputAssembly;
pipelineInfo.pViewportState         = &viewportState;
pipelineInfo.pRasterizationState    = &rasterizer;
pipelineInfo.pMultisampleState      = &multiSampling;
pipelineInfo.pDepthStencilState     = nullptr;
pipelineInfo.pColorBlendState       = &colorBlending;
pipelineInfo.pDynamicState          = &dynamicState;
pipelineInfo.layout                 = pipelineLayout;
pipelineInfo.renderPass             = renderPass;
pipelineInfo.subpass                = 0;
pipelineInfo.basePipelineHandle     = VK_NULL_HANDLE;
pipelineInfo.basePipelineIndex      = -1;

if (vkCreatePipelineLayout(m_Context->device, &pipelineLayoutInfo, nullptr, &pipelineLayout) != VK_SUCCESS)
    Utils::Logger::logMSG("Failed to create pipeline layout\n", "Rendering", Utils::Category::Error);

if (vkCreateGraphicsPipelines(m_Context->device, VK_NULL_HANDLE, 1, &pipelineInfo, nullptr, &graphicsPipeline) != VK_SUCCESS)
    Utils::Logger::logMSG("Failed to create graphics pipeline\n", "Rendering", Utils::Category::Error);

着色器代码

std::vector<char> VulkanShader::readFile(const std::string& filename)
{
    std::ifstream file(filename, std::ios::ate | std::ios::binary);

    if (!file.is_open())
        throw std::runtime_error("failed to open file");

    size_t fileSize = (size_t)file.tellg();
    std::vector<char> buffer(fileSize);

    file.seekg(0);
    file.read(buffer.data(), fileSize);

    file.close();

    return buffer;
}

void VulkanShader::setShader(std::string p_VertexShader, std::string p_FragmentShader)
{
    auto vertShaderCode = readFile(p_VertexShader);
    auto fragShaderCode = readFile(p_FragmentShader);

    vertShaderModule = createShaderModule(vertShaderCode);
    fragShaderModule = createShaderModule(fragShaderCode);

    vertShaderStageInfo = {};
    vertShaderStageInfo.sType = VK_STRUCTURE_TYPE_PIPELINE_SHADER_STAGE_CREATE_INFO;
    vertShaderStageInfo.stage = VK_SHADER_STAGE_VERTEX_BIT;

    vertShaderStageInfo.module = vertShaderModule;
    vertShaderStageInfo.pName = "main";

    fragShaderStageInfo = {};
    fragShaderStageInfo.sType = VK_STRUCTURE_TYPE_PIPELINE_SHADER_STAGE_CREATE_INFO;
    fragShaderStageInfo.stage = VK_SHADER_STAGE_FRAGMENT_BIT;

    fragShaderStageInfo.module = fragShaderModule;
    fragShaderStageInfo.pName = "main";
}

VkShaderModule VulkanShader::createShaderModule(const std::vector<char>& p_Code)
{
    VkShaderModuleCreateInfo createInfo = {};
    createInfo.sType = VK_STRUCTURE_TYPE_SHADER_MODULE_CREATE_INFO;
    createInfo.codeSize = p_Code.size();
    createInfo.pCode = reinterpret_cast<const uint32_t*>(p_Code.data());

    VkShaderModule shaderModule;
    if (vkCreateShaderModule(vkContextSingleton::getInstance().device, &createInfo, nullptr, &shaderModule) != VK_SUCCESS)
        Utils::Logger::logMSG("Failed to create shader module\n", "Shader", Utils::Category::Error);

    return shaderModule;
}

这是错误信息

Exception thrown at 0x00007FFC0171261B (amdvlk64.dll) in vulkan.exe: 
0xC0000005: Access violation reading location 0xFFFFFFFFFFFFFFFF.

控制台的输出(没有真正格式化，我只是想让事情先行)

感谢您的帮助。

评论帮助我意识到我的验证层不起作用。我自己认为他们做到了。忘记在实例创建中启用验证层。
