Vulkan 验证层不断在 VkQueuePresentKHR() 上抛出图像布局错误

Question

明显的菜鸟警告。 从昨天开始学习Vulkan，正如标题所说，我一直在提交时出现上述错误。 我已经检查了教程中的代码，但找不到任何明显的错误。 这是我的 RenderPass 创建代码：

VkAttachmentDescription colorAttachmentDescription = {};
    colorAttachmentDescription.format = this->surfaceFormat.format;
    colorAttachmentDescription.samples = VK_SAMPLE_COUNT_1_BIT;
    colorAttachmentDescription.storeOp = VK_ATTACHMENT_STORE_OP_STORE;
    colorAttachmentDescription.loadOp = VK_ATTACHMENT_LOAD_OP_CLEAR;
    colorAttachmentDescription.stencilLoadOp = VK_ATTACHMENT_LOAD_OP_DONT_CARE;
    colorAttachmentDescription.stencilStoreOp = VK_ATTACHMENT_STORE_OP_DONT_CARE;
    colorAttachmentDescription.initialLayout = VK_IMAGE_LAYOUT_UNDEFINED;
    colorAttachmentDescription.finalLayout = VK_IMAGE_LAYOUT_PRESENT_SRC_KHR;


    VkAttachmentReference attachmentReference = {};
    attachmentReference.attachment = 0;
    attachmentReference.layout = VK_IMAGE_LAYOUT_COLOR_ATTACHMENT_OPTIMAL;


    VkSubpassDescription subpassDescription = {};
    subpassDescription.colorAttachmentCount = 1;
    subpassDescription.pColorAttachments = &attachmentReference;
    subpassDescription.pipelineBindPoint = VK_PIPELINE_BIND_POINT_GRAPHICS;


    VkSubpassDependency subpassDependency = {};
    subpassDependency.srcSubpass = VK_SUBPASS_EXTERNAL;
    subpassDependency.dstSubpass = 0;
    subpassDependency.srcAccessMask = 0;
    subpassDependency.srcStageMask = VK_PIPELINE_STAGE_COLOR_ATTACHMENT_OUTPUT_BIT;
    subpassDependency.dstStageMask = VK_PIPELINE_STAGE_COLOR_ATTACHMENT_OUTPUT_BIT;
    subpassDependency.dstAccessMask = VK_ACCESS_COLOR_ATTACHMENT_READ_BIT | VK_ACCESS_COLOR_ATTACHMENT_WRITE_BIT;


    VkRenderPassCreateInfo renderPassCreateInfo = {};
    renderPassCreateInfo.sType = VK_STRUCTURE_TYPE_RENDER_PASS_CREATE_INFO;
    renderPassCreateInfo.attachmentCount = 1;
    renderPassCreateInfo.pAttachments = &colorAttachmentDescription;
    renderPassCreateInfo.subpassCount = 1;
    renderPassCreateInfo.pSubpasses = &subpassDescription;
    renderPassCreateInfo.dependencyCount = 1;
    renderPassCreateInfo.pDependencies = &subpassDependency;


    vkCreateRenderPass(logicalDevice, &renderPassCreateInfo, nullptr, &renderPass);

哦，我什至尝试将 initialLayout 更改为VK_IMAGE_LAYOUT_PRESENT_SRC_KHR ，但仍然出现错误。 这是我得到的验证层错误。

VALIDATION LAYER : Images passed to present must be in layout VK_IMAGE_LAYOUT_PRESENT_SRC_KHR or VK_IMAGE_LAYOUT_SHARED_PRESENT_KHR but is in VK_IMAGE_LAYOUT_UNDEFINED. The Vulkan spec states: Each element of pImageIndices must be the index of a presentable image acquired from the swapchain specified by the corresponding element of the pSwapchains array, and the presented image subresource must be in the VK_IMAGE_LAYOUT_PRESENT_SRC_KHR layout at the time the operation is executed on a VkDevice (https://www.khronos.org/registry/vulkan/specs/1.1-extensions/html/vkspec.html#VUID-VkPresentInfoKHR-pImageIndices-01296)

问题在于您发布的代码中省略了渲染过程的创建。

仔细检查VkRenderPassCreateInfo中的VkAttachmentDescription条目。

还要检查attachmentCount是否不为零。
